MENGGUNAKAN BATAKO LEBIH HEMAT

Salah satu bagian terpenting dalam membangun sebuah bangunan / rumah adalah dinding. Semakin majunya zaman, teknik membuat bangunan dan bahan-bahan yang di gunakan sebagi pembuat dinding rumah sangat bervariatif. Hal tersebut tidak terlepas seiring perkembangan ilmu pengetahuan dan teknologi serta semakin minimnya sumber bahan baku berupa tanah liat sebagai bahan batu bata merah. Namun di era modern saat ini sangat beraneka ragam, mulai dari hebel, bata ringan, batako, paving dll.

PEMBUATAN BATAKO PRES

Batako adalah bahan banguanan yang terbuat dari campuran pasir, semen yang dicetak atau di press padat, selain itu batako juga dapat dibuat dari bahan batu tras, kapur dan air. Batako pres dibuat dari campuran semen PC dan pasir atau abu batu. Ada yang dibuat secara manual (menggunakan tangan), ada juga yang menggunakan mesin press batako. Perbedaannya bisa dilihat pada kepadatan permukaan batakonya. Umumnya memiliki ukuran panjang 36-40 cm, tebal 8–10 cm, dan tinggi 18-20 cm. Untuk dinding seluas 1 m2, kira-kira membutuhkan:

    Batako pres = 15 buah
    Semen PC = 0,125 sak
    Pasir ayak (pasir pasang} = 0,015 m3

• Kelebihan dinding batako press:

    Kedap air sehingga sangat kecil kemungkinan terjadinya rembesan air.
    Pemasangan lebih cepat.
    Penggunaan rangka beton pengakunya lebih luas, antara 9 – 12 m2.

Setelah batako jadi, baik di buat dengan press cetak manual atau mesin press batako, hasilnya  secara fisik , batako memiliki rongga kosong di bagian dalamnya. Bagian tersebut berfungsi sebagai insulasi panas, juga sebagai insulasi suara. Dengan tujuan bisa menciptakan kondisi dalam ruangan yang menggunakan materi batako terasa relatif lebih sejuk dan nyaman.

•  Kekurangan dinding batako pres:

    Mudah terjadi retak rambut pada dinding.
    Mudah dilubangi karena terdapat lubang pada bagian sisi dalamnya

Kekurangan ini yang membuat sebagian orang kurang suka menggunakan batako sebagai material dinding rumahnya. Namun , kendala tersebut dapat diatasi dengan penggunaan penggantung yang bersifat suction-cup hooks dan strong-adhesive hooks yang berdaya rekat tinggi. Penggantung multi-adhesive ini memiliki sifat pemasangan dan pelepasan yang relatif mudah. Dari harganya yang murah di bandingkan dengan bata merah, bangunan yang dibuat dengan batako akan menghemat pengeluaran uang untuk membuat banguanan. Selanjutnya jika ada anggapan bahwa batako kurang kokoh, bisa di atasi dengan menambah campuran material dasar batako dengan ampas tebu. Ampas tebu tersebut akan memberikan hasil yang lebih kuat, ringan dan tahan lama serta tentunya harganya lebih terjangkau.

TIPS - PEMAKAIAN AC HEMAT LISTRIK

Kecenderungan penghematan energi tidak sekadar lantaran isu global warming. Lebih dari itu, penghematan energi pun juga benar-benar terhubung lewat mengoreksi perilaku, dengan begitu anda juga dapat lebih bisa menjadi satu bersama alam. Sektor rumah tangga memakan kurang lebih 10,3 persen dari keseluruhan energi di tanah air. Pemanfaatan energi terbanyak berpangkal dari pemakaian sparepart ac yang salah, ac serta kulkas. Maka apabila berniat untuk mengawali penghematan listrik, cermati sparepart ac kebutuhan kedua peranti itu, baru dari sana anda dapat merintis

pengiritan listrik.

Seberapa banyak penghematan yang dapat anda kerjakan lewat untuk mengganti konsumsi peranti listrik di tempat tinggal anda? Lihat sejumlah metode mengirit energi di rumah layaknya yang dijelaskan tim Energy Efficiency and Conservation Clearing House Indonesia (EECHI) selanjutnya ini :

1. Pendingin Ruang (AC) juga mampu untuk menghemat 130 ribu setiap bulan
Apabila Anda hendak berhemat, gantilah budaya Anda memakai AC di bawah 24 derajat C. Kecuali tubuh lebih bugar, temperatur ideal 24 -25 derajat C pun juga dapat berpeluang mengirit listrik sampai 130 ribu setiap bulan. Tiap-tiap mengurangi temperatur 1 derajat C untuk AC, untuk itu konsumsi listrik naik 6 persen. Anda pun juga dapat membersihkan dengan rutin filter, kondensor,  juga koil AC. AC kotor merupakan inefisiensi energi. Kecuali itu, Anda hendaknya menutup akses udara keluar semacam  jendela, pintu,juga bukaan lain supaya udara dingin tidak terbiar percuma.

2. Pemakaian Lampu mampu menghemat 55 ribu setiap bulan
Gantilah setiap lampu pijar menggunakan Compact Fluorescent Light (lampu hemat energi). CFL juga mampu mengirit lebih dari 50 persen biaya listrik. Kecuali itu, Anda juga dapat mematikan lampu bilamana tak dipakai. Pemeliharaan lampu (membersihkannya dari debu) pun dapat meniadakan kans penurunan daya penerangan sampai 5 persen. Guna mengirit listrik, hendaknya matikan setiap alat elektronik kala tak dipakai. Cabutlah kabel listrik dari stop kontak. Energi tetap terbiar percuma ketika kabel terus pada kondisi stand by. Penghematan paling banyak dapat ditempuh lewat menukar komputer desktop menggunakan laptop. Pengiritannya sampai-sampai menembus lima kali ketimbang komputer desktop.

3. Kulkas mampu menghemat hingga 10 ribu setiap bulan
Aturlah temperatur ideal kulkas di 2 hingga 4 derajat C. Sementara pada freezer, temperatur boleh diatur di 17 – 15 derajat C. Lebih baik Anda pun menukar kulkas yang telah lebih dari 10 thn.. Hal tersebut juga dapat memangkas biaya listrik sampai 75 persen. Sebagai pengiritan optimal, Anda dapat juga memangkas frekuensi membuka pintu kulkas lantaran 7 persen energi terbuang percuma ketika pintu terbuka kelewat kerap juga kelewat lama.

Penghematan semestinya ditempuh atas kesadaran, tidak keterpaksaan. So, pengiritan tidak mesti menurunkan kenyamanan bekerja, namun malahan dapat menambah produktivitas serta derajat kesehatan. Nah, bila mengikuti pengiritan layaknya di atas, pengiritan pemakaian listrik Anda dapat menembus sampai 2,8 juta setiap tahun! Sangat banyak yang bisa dihemat.

Finding Scandal in New York and New Jersey, but No Shame

From sea to shining sea, or at least from one side of the Hudson to the other, politicians you have barely heard of are being accused of wrongdoing. There were so many court proceedings involving public officials on Monday that it was hard to keep up.

In Newark, two underlings of Gov. Chris Christie were arraigned on charges that they were in on the truly deranged plot to block traffic leading onto the George Washington Bridge.

Ten miles away, in Lower Manhattan, Dean G. Skelos, the leader of the New York State Senate, and his son, Adam B. Skelos, were arrested by the Federal Bureau of Investigation on accusations of far more conventional political larceny, involving a job with a sewer company for the son and commissions on title insurance and bond work.

The younger man managed to receive a 150 percent pay increase from the sewer company even though, as he said on tape, he “literally knew nothing about water or, you know, any of that stuff,” according to a criminal complaint the United States attorney’s office filed.

The success of Adam Skelos, 32, was attributed by prosecutors to his father’s influence as the leader of the Senate and as a potentate among state Republicans. The indictment can also be read as one of those unfailingly sad tales of a father who cannot stop indulging a grown son. The senator himself is not alleged to have profited from the schemes, except by being relieved of the burden of underwriting Adam.

The bridge traffic caper is its own species of crazy; what distinguishes the charges against the two Skeloses is the apparent absence of a survival instinct. It is one thing not to know anything about water or that stuff. More remarkable, if true, is the fact that the sewer machinations continued even after the former New York Assembly speaker, Sheldon Silver, was charged in January with taking bribes disguised as fees.

It was by then common gossip in political and news media circles that Senator Skelos, a Republican, the counterpart in the Senate to Mr. Silver, a Democrat, in the Assembly, could be next in line for the criminal dock. “Stay tuned,” the United States attorney, Preet Bharara said, leaving not much to the imagination.

Even though the cat had been unmistakably belled, Skelos father and son continued to talk about how to advance the interests of the sewer company, though the son did begin to use a burner cellphone, the kind people pay for in cash, with no traceable contracts.

That was indeed prudent, as prosecutors had been wiretapping the cellphones of both men. But it would seem that the burner was of limited value, because by then the prosecutors had managed to secure the help of a business executive who agreed to record calls with the Skeloses. It would further seem that the business executive was more attentive to the perils of pending investigations than the politician.

Through the end of the New York State budget negotiations in March, the hopes of the younger Skelos rested on his father’s ability to devise legislation that would benefit the sewer company. That did not pan out. But Senator Skelos did boast that he had haggled with Gov. Andrew M. Cuomo, a Democrat, in a successful effort to raise a $150 million allocation for Long Island to $550 million, for what the budget called “transformative economic development projects.” It included money for the kind of work done by the sewer company.

The lawyer for Adam Skelos said he was not guilty and would win in court. Senator Skelos issued a ringing declaration that he was unequivocally innocent.

THIS was also the approach taken in New Jersey by Bill Baroni, a man of great presence and eloquence who stopped outside the federal courthouse to note that he had taken risks as a Republican by bucking his party to support paid family leave, medical marijuana and marriage equality. “I would never risk my career, my job, my reputation for something like this,” Mr. Baroni said. “I am an innocent man.”

The lawyer for his co-defendant, Bridget Anne Kelly, the former deputy chief of staff to Mr. Christie, a Republican, said that she would strongly rebut the charges.

Perhaps they had nothing to do with the lane closings. But neither Mr. Baroni nor Ms. Kelly addressed the question of why they did not return repeated calls from the mayor of Fort Lee, N.J., begging them to stop the traffic tie-ups, over three days.

That silence was a low moment. But perhaps New York hit bottom faster. Senator Skelos, the prosecutors charged, arranged to meet Long Island politicians at the wake of Wenjian Liu, a New York City police officer shot dead in December, to press for payments to the company employing his son.

Sometimes it seems as though for some people, the only thing to be ashamed of is shame itself.

Tribute for a Roller Hockey Warrior

Hockey is not exactly known as a city game, but played on roller skates, it once held sway as the sport of choice in many New York neighborhoods.

“City kids had no rinks, no ice, but they would do anything to play hockey,” said Edward Moffett, former director of the Long Island City Y.M.C.A. Roller Hockey League, in Queens, whose games were played in city playgrounds going back to the 1940s.

From the 1960s through the 1980s, the league had more than 60 teams, he said. Players included the Mullen brothers of Hell’s Kitchen and Dan Dorion of Astoria, Queens, who would later play on ice for the National Hockey League.

One street legend from the heyday of New York roller hockey was Craig Allen, who lived in the Woodside Houses projects and became one of the city’s hardest hitters and top scorers.

“Craig was a warrior, one of the best roller hockey players in the city in the ’70s,” said Dave Garmendia, 60, a retired New York police officer who grew up playing with Mr. Allen. “His teammates loved him and his opponents feared him.”

Young Craig took up hockey on the streets of Queens in the 1960s, playing pickup games between sewer covers, wearing steel-wheeled skates clamped onto school shoes and using a roll of electrical tape as the puck.

His skill and ferocity drew attention, Mr. Garmendia said, but so did his skin color. He was black, in a sport made up almost entirely by white players.

“Roller hockey was a white kid’s game, plain and simple, but Craig broke the color barrier,” Mr. Garmendia said. “We used to say Craig did more for race relations than the N.A.A.C.P.”

Mr. Allen went on to coach and referee roller hockey in New York before moving several years ago to South Carolina. But he continued to organize an annual alumni game at Dutch Kills Playground in Long Island City, the same site that held the local championship games.

The reunion this year was on Saturday, but Mr. Allen never made it. On April 26, just before boarding the bus to New York, he died of an asthma attack at age 61.

Word of his death spread rapidly among hundreds of his old hockey colleagues who resolved to continue with the event, now renamed the Craig Allen Memorial Roller Hockey Reunion.

The turnout on Saturday was the largest ever, with players pulling on their old equipment, choosing sides and taking once again to the rink of cracked blacktop with faded lines and circles. They wore no helmets, although one player wore a fedora.

Another, Vinnie Juliano, 77, of Long Island City, wore his hearing aids, along with his 50-year-old taped-up quads, or four-wheeled skates with a leather boot. Many players here never converted to in-line skates, and neither did Mr. Allen, whose photograph appeared on a poster hanging behind the players’ bench.

“I’m seeing people walking by wondering why all these rusty, grizzly old guys are here playing hockey,” one player, Tommy Dominguez, said. “We’re here for Craig, and let me tell you, these old guys still play hard.”

Everyone seemed to have a Craig Allen story, from his earliest teams at Public School 151 to the Bryant Rangers, the Woodside Wings, the Woodside Blues and more.

Mr. Allen, who became a yellow-cab driver, was always recruiting new talent. He gained the nickname Cabby for his habit of stopping at playgrounds all over the city to scout players.

Teams were organized around neighborhoods and churches, and often sponsored by local bars. Mr. Allen, for one, played for bars, including Garry Owen’s and on the Fiddler’s Green Jokers team in Inwood, Manhattan.

Play was tough and fights were frequent.

“We were basically street gangs on skates,” said Steve Rogg, 56, a mail clerk who grew up in Jackson Heights, Queens, and who on Saturday wore his Riedell Classic quads from 1972. “If another team caught up with you the night before a game, they tossed you a beating so you couldn’t play the next day.”

Mr. Garmendia said Mr. Allen’s skin color provoked many fights.

“When we’d go to some ignorant neighborhoods, a lot of players would use slurs,” Mr. Garmendia said, recalling a game in Ozone Park, Queens, where local fans parked motorcycles in a lineup next to the blacktop and taunted Mr. Allen. Mr. Garmendia said he checked a player into the motorcycles, “and the bikes went down like dominoes, which started a serious brawl.”

A group of fans at a game in Brooklyn once stuck a pole through the rink fence as Mr. Allen skated by and broke his jaw, Mr. Garmendia said, adding that carloads of reinforcements soon arrived to defend Mr. Allen.

And at another racially incited brawl, the police responded with six patrol cars and a helicopter.

Before play began on Saturday, the players gathered at center rink to honor Mr. Allen. Billy Barnwell, 59, of Woodside, recalled once how an all-white, all-star squad snubbed Mr. Allen by playing him third string. He scored seven goals in the first game and made first string immediately.

“He’d always hear racial stuff before the game, and I’d ask him, ‘How do you put up with that?’” Mr. Barnwell recalled. “Craig would say, ‘We’ll take care of it,’ and by the end of the game, he’d win guys over. They’d say, ‘This guy’s good.’”

Advertisement Politics Obama Finds a Bolder Voice on Race Issues

As he reflected on the festering wounds deepened by race and grievance that have been on painful display in America’s cities lately, President Obama on Monday found himself thinking about a young man he had just met named Malachi.

A few minutes before, in a closed-door round-table discussion at Lehman College in the Bronx, Mr. Obama had asked a group of black and Hispanic students from disadvantaged backgrounds what could be done to help them reach their goals. Several talked about counseling and guidance programs.

“Malachi, he just talked about — we should talk about love,” Mr. Obama told a crowd afterward, drifting away from his prepared remarks. “Because Malachi and I shared the fact that our dad wasn’t around and that sometimes we wondered why he wasn’t around and what had happened. But really, that’s what this comes down to is: Do we love these kids?”

Many presidents have governed during times of racial tension, but Mr. Obama is the first to see in the mirror a face that looks like those on the other side of history’s ledger. While his first term was consumed with the economy, war and health care, his second keeps coming back to the societal divide that was not bridged by his election. A president who eschewed focusing on race now seems to have found his voice again as he thinks about how to use his remaining time in office and beyond.

Obama Speaks of a ‘Sense of Unfairness’

In the aftermath of racially charged unrest in places like Baltimore, Ferguson, Mo., and New York, Mr. Obama came to the Bronx on Monday for the announcement of a new nonprofit organization that is being spun off from his White House initiative called My Brother’s Keeper. Staked by more than $80 million in commitments from corporations and other donors, the new group, My Brother’s Keeper Alliance, will in effect provide the nucleus for Mr. Obama’s post-presidency, which will begin in January 2017.

“This will remain a mission for me and for Michelle not just for the rest of my presidency but for the rest of my life,” Mr. Obama said. “And the reason is simple,” he added. Referring to some of the youths he had just met, he said: “We see ourselves in these young men. I grew up without a dad. I grew up lost sometimes and adrift, not having a sense of a clear path. The only difference between me and a lot of other young men in this neighborhood and all across the country is that I grew up in an environment that was a little more forgiving.”

Organizers said the new alliance already had financial pledges from companies like American Express, Deloitte, Discovery Communications and News Corporation. The money will be used to help companies address obstacles facing young black and Hispanic men, provide grants to programs for disadvantaged youths, and help communities aid their populations.

Joe Echevarria, a former chief executive of Deloitte, the accounting and consulting firm, will lead the alliance, and among those on its leadership team or advisory group are executives at PepsiCo, News Corporation, Sprint, BET and Prudential Group Insurance; former Secretary of State Colin L. Powell; Senator Cory Booker, Democrat of New Jersey; former Attorney General Eric H. Holder Jr.; the music star John Legend; the retired athletes Alonzo Mourning, Jerome Bettis and Shaquille O’Neal; and the mayors of Indianapolis, Sacramento and Philadelphia.

The alliance, while nominally independent of the White House, may face some of the same questions confronting former Secretary of State Hillary Rodham Clinton as she begins another presidential campaign. Some of those donating to the alliance may have interests in government action, and skeptics may wonder whether they are trying to curry favor with the president by contributing.

“The Obama administration will have no role in deciding how donations are screened and what criteria they’ll set at the alliance for donor policies, because it’s an entirely separate entity,” Josh Earnest, the White House press secretary, told reporters on Air Force One en route to New York. But he added, “I’m confident that the members of the board are well aware of the president’s commitment to transparency.”

The alliance was in the works before the disturbances last week after the death of Freddie Gray, the black man who suffered fatal injuries while in police custody in Baltimore, but it reflected the evolution of Mr. Obama’s presidency. For him, in a way, it is coming back to issues that animated him as a young community organizer and politician. It was his own struggle with race and identity, captured in his youthful memoir, “Dreams From My Father,” that stood him apart from other presidential aspirants.

But that was a side of him that he kept largely to himself through the first years of his presidency while he focused on other priorities like turning the economy around, expanding government-subsidized health care and avoiding electoral land mines en route to re-election.

After securing a second term, Mr. Obama appeared more emboldened. Just a month after his 2013 inauguration, he talked passionately about opportunity and race with a group of teenage boys in Chicago, a moment aides point to as perhaps the first time he had spoken about these issues in such a personal, powerful way as president. A few months later, he publicly lamented the death of Trayvon Martin, a black Florida teenager, saying that “could have been me 35 years ago.”

That case, along with public ruptures of anger over police shootings in Ferguson and elsewhere, have pushed the issue of race and law enforcement onto the public agenda. Aides said they imagined that with his presidency in its final stages, Mr. Obama might be thinking more about what comes next and causes he can advance as a private citizen.

That is not to say that his public discussion of these issues has been universally welcomed. Some conservatives said he had made matters worse by seeming in their view to blame police officers in some of the disputed cases.

“President Obama, when he was elected, could have been a unifying leader,” Senator Ted Cruz of Texas, a Republican candidate for president, said at a forum last week. “He has made decisions that I think have inflamed racial tensions.”

On the other side of the ideological spectrum, some liberal African-American activists have complained that Mr. Obama has not done enough to help downtrodden communities. While he is speaking out more, these critics argue, he has hardly used the power of the presidency to make the sort of radical change they say is necessary.

The line Mr. Obama has tried to straddle has been a serrated one. He condemns police brutality as he defends most officers as honorable. He condemns “criminals and thugs” who looted in Baltimore while expressing empathy with those trapped in a cycle of poverty and hopelessness.

In the Bronx on Monday, Mr. Obama bemoaned the death of Brian Moore, a plainclothes New York police officer who had died earlier in the day after being shot in the head Saturday on a Queens street. Most police officers are “good and honest and fair and care deeply about their communities,” even as they put their lives on the line, Mr. Obama said.

“Which is why in addressing the issues in Baltimore or Ferguson or New York, the point I made was that if we’re just looking at policing, we’re looking at it too narrowly,” he added. “If we ask the police to simply contain and control problems that we ourselves have been unwilling to invest and solve, that’s not fair to the communities, it’s not fair to the police.”

Moreover, if society writes off some people, he said, “that’s not the kind of country I want to live in; that’s not what America is about.”

His message to young men like Malachi Hernandez, who attends Boston Latin Academy in Massachusetts, is not to give up.

“I want you to know you matter,” he said. “You matter to us.”

Police Rethink Long Tradition on Using Force

WASHINGTON — During a training course on defending against knife attacks, a young Salt Lake City police officer asked a question: “How close can somebody get to me before I’m justified in using deadly force?”

Dennis Tueller, the instructor in that class more than three decades ago, decided to find out. In the fall of 1982, he performed a rudimentary series of tests and concluded that an armed attacker who bolted toward an officer could clear 21 feet in the time it took most officers to draw, aim and fire their weapon.

The next spring, Mr. Tueller published his findings in SWAT magazine and transformed police training in the United States. The “21-foot rule” became dogma. It has been taught in police academies around the country, accepted by courts and cited by officers to justify countless shootings, including recent episodes involving a homeless woodcarver in Seattle and a schizophrenic woman in San Francisco.

Meet Mago, Former Heavyweight

GREENWICH, Conn. — Mago is in the bedroom. You can go in.

The big man lies on a hospital bed with his bare feet scraping its bottom rail. His head is propped on a scarlet pillow, the left temple dented, the right side paralyzed. His dark hair is kept just long enough to conceal the scars.

The occasional sounds he makes are understood only by his wife, but he still has that punctuating left hand. In slow motion, the fingers curl and close. A thumbs-up greeting.

Hello, Mago.

This is Magomed Abdusalamov, 34, also known as the Russian Tyson, also known as Mago. He is a former heavyweight boxer who scored four knockouts and 14 technical knockouts in his first 18 professional fights. He preferred to stand between rounds. Sitting conveyed weakness.

But Mago lost his 19th fight, his big chance, at the packed Theater at Madison Square Garden in November 2013. His 19th decision, and his last.

Now here he is, in a small bedroom in a working-class neighborhood in Greenwich, in a modest house his family rents cheap from a devoted friend. The air-pressure machine for his mattress hums like an expectant crowd.

Today is like any other day, except for those days when he is hurried in crisis to the hospital. Every three hours during the night, his slight wife, Bakanay, 28, has risen to turn his 6-foot-3 body — 210 pounds of dead weight. It has to be done. Infections of the gaping bedsore above his tailbone have nearly killed him.

Then, with the help of a young caretaker, Baka has gotten two of their daughters off to elementary school and settled down the toddler. Yes, Mago and Baka are blessed with all girls, but they had also hoped for a son someday.

They feed Mago as they clean him; it’s easier that way. For breakfast, which comes with a side of crushed antiseizure pills, he likes oatmeal with a squirt of Hershey’s chocolate syrup. But even oatmeal must be puréed and fed to him by spoon.

He opens his mouth to indicate more, the way a baby does. But his paralysis has made everything a choking hazard. His water needs a stirring of powdered food thickener, and still he chokes — eh-eh-eh — as he tries to cough up what will not go down.

Mago used to drink only water. No alcohol. Not even soda. A sip of juice would be as far as he dared. Now even water betrays him.

With the caretaker’s help, Baka uses a washcloth and soap to clean his body and shampoo his hair. How handsome still, she has thought. Sometimes, in the night, she leaves the bedroom to watch old videos, just to hear again his voice in the fullness of life. She cries, wipes her eyes and returns, feigning happiness. Mago must never see her sad.

Photo

 

When Baka finishes, Mago is cleanshaven and fresh down to his trimmed and filed toenails. “I want him to look good,” she says.

Theirs was an arranged Muslim marriage in Makhachkala, in the Russian republic of Dagestan. He was 23, she was 18 and their future hinged on boxing. Sometimes they would shadowbox in love, her David to his Goliath. You are so strong, he would tell her.

His father once told him he could either be a bandit or an athlete, but if he chose banditry, “I will kill you.” This paternal advice, Mago later told The Ventura County Reporter, “made it a very easy decision for me.”

Mago won against mediocre competition, in Moscow and Hollywood, Fla., in Las Vegas and Johnstown, Pa. He was knocked down only once, and even then, it surprised more than hurt. He scored a technical knockout in the next round.

It all led up to this: the undercard at the Garden, Mike Perez vs. Magomed Abdusalamov, 10 rounds, on HBO. A win, he believed, would improve his chances of taking on the heavyweight champion Wladimir Klitschko, who sat in the crowd of 4,600 with his fiancée, the actress Hayden Panettiere, watching.

Wearing black-and-red trunks and a green mouth guard, Mago went to work. But in the first round, a hard forearm to his left cheek rocked him. At the bell, he returned to his corner, and this time, he sat down. “I think it’s broken,” he repeatedly said in Russian.

Maybe at that point, somebody — the referee, the ringside doctors, his handlers — should have stopped the fight, under a guiding principle: better one punch too early than one punch too late. But the bloody trade of blows continued into the seventh, eighth, ninth, a hand and orbital bone broken, his face transforming.

Meanwhile, in the family’s apartment in Miami, Baka forced herself to watch the broadcast. She could see it in his swollen eyes. Something was off.

After the final round, Perez raised his tattooed arms in victory, and Mago wandered off in a fog. He had taken 312 punches in about 40 minutes, for a purse of $40,000.

In the locker room, doctors sutured a cut above Mago’s left eye and tested his cognitive abilities. He did not do well. The ambulance that waits in expectation at every fight was not summoned by boxing officials.

Blood was pooling in Mago’s cranial cavity as he left the Garden. He vomited on the pavement while his handlers flagged a taxi to St. Luke’s-Roosevelt Hospital. There, doctors induced a coma and removed part of his skull to drain fluids and ease the swelling.

Then came the stroke.

It is lunchtime now, and the aroma of puréed beef and potatoes lingers. So do the questions.

How will Mago and Baka pay the $2 million in medical bills they owe? What if their friend can no longer offer them this home? Will they win their lawsuits against the five ringside doctors, the referee, and a New York State boxing inspector? What about Mago’s future care?

Most of all: Is this it?

A napkin rests on Mago’s chest. As another spoonful of mush approaches, he opens his mouth, half-swallows, chokes, and coughs until it clears. Eh-eh-eh. Sometimes he turns bluish, but Baka never shows fear. Always happy for Mago.

Some days he is wheeled out for physical therapy or speech therapy. Today, two massage therapists come to knead his half-limp body like a pair of skilled corner men.

Soon, Mago will doze. Then his three daughters, ages 2, 6 and 9, will descend upon him to talk of their day. Not long ago, the oldest lugged his championship belt to school for a proud show-and-tell moment. Her classmates were amazed at the weight of it.

Then, tonight, there will be more puréed food and pulverized medication, more coughing, and more tender care from his wife, before sleep comes.

Goodbye, Mago.

He half-smiles, raises his one good hand, and forms a fist.
