Bekasi, Saco-Indonesia.com - Segmen yang selama ini diam, terletak 37 km di selatan Kroya, Jawa Tengah, pada sabtu (25/1/2014) bersuara. Gejolak segmen itu menimbulkan gempa yang mengguncang wilayah hampir seluruh Jawa dengan goncangan terkuat di Kebumen.

Menurut informasi dari United States Geological Survey (USGS), gempa bermagnitud 6,1, terjadi pada pukul 12.14 WIB, pada kedalaman 89,1 km. Gempa tidak menimbulkan tsunami tapi disusul oleh 6 gempa susulan.

Terkait gempa tersebut, pakar tektonik dari Institut Teknologi Bandung (ITB), Irwan Meilano, sempat mengungkapkan adanya potensi gempa Kebumen untuk tidak hanya mengakibatkan gempa susulan, tetapi juga gempa yang terpicu (triggerred earthquake).

Irwan mengatakan, gempa yang terpicu oleh gempa Kebumen itu "bisa memiliki magnitud yang lebih besar dari gempa sebelumnya." (Baca artikel "Waspada, Gempa Kebumen Bisa Memicu Gempa Lebih Besar").

Peringatan ini mendapatkan respon beragam dalam kotak komentar di Kompas.com maupun media sosial Twitter, salah satunya adalah ketakutan dan tuduhan bahwa informasi tentang potensi gempa yang terpicu adalah upaya menakut-nakuti masyarakat.

"Jangan nakut-nakuti bos!" demikian komentar salah satu pembaca Kompas.com dengan akun bernama Juragan Minyak - kecewa Gubernur DKI abaikan sumber polusi bising di ibu kota, pada Sabtu pukul 20.19 WIB.

Sementara, di Twitter, pengguna bernama Dariel Siregar mengatakan, "Kepo!! Berita buat masyarakat resah aje." Anggi Anggarini punya kicauan hampir sama. "Jangan nakut2in donk :'(," katanya.

Haruskah Panik dan Takut?

Menanggapi komentar pembaca, Irwan memahami bahwa informasi potensi gempa memang bisa membuat publik panik. Tak sepenuhnya salah, sebab Indonesia memang memiliki historis gempa mematikan, seperti gempa Aceh tahun 2004 dan gempa Yogyakarta tahun 2006.

Namun, ia menegaskan bahwa tujuan pemberian informasi bukanlah untuk membuat panik. "Informasi potensi bencana memang harus diberikan untuk meningkatkan kewaspadaan kita," kata Irwan saat dihubungi Kompas.com, Minggu (26/1/2014).

Irwan mengungkapkan, seringkali terjadi, Indonesia menganggap rendah potensi bencana. Informasi yang diberikan kepada masyarakat tidak sesuai dengan potensi yang sebenarnya. "Agar masyarakat tenang," tuturnya.

Menurutnya, bencana-bencana yang merenggut banyak nyawa dan membuat negara merugi sebenarnya adalah akumulasi dari ketidakpedulian kita pada potensi bencana. "Kalau kita meng-underestimate potensi gempa, ini juga salah satu bentuk ignorance," ungkapnya.

Informasi potensi gempa yang sebenarnya memang bisa membuat panik dan takut. Namun, bagaimanapun tetap perlu diberikan dengan cara komunikasi yang pas sehingga tumbuh kesiapsiagaan menghadapi bencana serta perubahan sikap.

Irwan menuturkan, sejarah memang mengharuskan warga yang hidup di selatan Jawa untuk mewaspadai gempa. Aktivitas lempeng lautan terbukti telah memicu gempa dan tsunami di Banyuwangi pada tahun 1994 dan gempa dan tsunami Pangandaran tahun 2006.

Mengapa tak detail?

Akun Andri Jalu menulis dalam kotak komentar di Kompas.com, "Jelaskan dengan lebih detil tentang selang waktu gempa yang terpicu, buat orang awam yg bukan ahli, jadi tidak menimbulkan ketakutan kalo ada yg membaca artikel ini."

Mungkin memang sebuah keharusan bila pemberitahuan ancaman disertai dengan detail selang waktu gempa yang terpicu akan terjadi, wilayah mana yang kemungkinan mengalami, dan berapa besarnya. Sayangnya, detail tersebut sulit didapatkan.

Widjo Kongko, peneliti gempa dan tsunami dari Badan Pengkajian dan Penerapan Teknologi (BPPT), mengatakan bahwa gempa Kebumen terjadi di segmen yang jarang bergejolak. Dalam 4 dekade, cuma ada 10 gempa dengan magnitud lebih dari 5 yang terjadi di segmen itu.

Pada saat yang sama, patahan dan segmen penyebab gempa di selatan Jawa belum banyak terpetakan seperti di Sumatera. Karenanya, Widjo menyebut bahwa pengetahuan tentang wilayah tersebut masih gelap.

Karena belum banyak dipelajari, sulit memerkirakan wilayah yang akan terpicu aktivitasnya akibat gempa Kebumen kemarin, di samping memang sampai saat ini sulit memerkirakan waktu dan lokasi yang akan mengalami gempa.

Widjo hanya bisa memberi petunjuk lokasi yang masih umum. "Lokasi di Jawa selatan, bisa mendekati palung atau sebaliknya, ke daratan," ungkapnya. Berapa lama setelah gempa Kebumen gempa terpicu mungkin terjadi, belum bisa dikatakan.

Irwan mengungkapkan, gempa Kebumen kemarin terjadi dengan mekanisme sesar turun akibat slab pull. Slab pull secara sederhana adalah bergeraknya lempeng samudera karena adanya tarikan lempeng samudera yang berada di zona subduksi.

Menurut Irwan, gerakan turun lempeng akibat gempa Kebumen cukup curam. Ini bisa berarti bahwa bagian atas lempeng tersebut saat ini memiliki akumulasi energi dan berpotensi menimbulkan gempa yang terpicu.

"Jadi yang bisa diberikan, gempa yang terpicu ini mungkin terjadi di wilayah yang lebih dangkal," ungkapnya. Wilayah dangkal berarti berada pada kedalaman palung hingga 50 kilometer.

Gempa dangkal memang hanya akan dirasakan di wilayah yang cakupannya lebih sempit. Namun, goncangannya akan lebih terasa dampaknya jauh lebih merusak. Gempa Yogyakarta pada tahun 2006 dengan kedalaman episentrum hanya 10 km adalah salah satu gempa dangkal.

Gempa dangkal yang terjadi di lautan juga bisa berarti memiliki potensi tsunami bila gerakan sesarnya naik. Dengan goncangan lebih besar dan berpotensi tsunami, maka suatu gempa akan lebih mematikan.

Di luar konteks gempa yang terpicu, gempa Kebumen juga memberi petunjuk bahwa subduksi Jawa aktif. Selama ini, seringkali dianggap bahwa subduksi Jawa aseismik, tidak seaktif subduksi Sumatera.

Ilmuwan membagi subduksi Jawa menjadi tiga bagian, Selat Sunda hingga selatan Jawa Barat, selatan Jawa Tengah, serta selatan Jawa Timur hingga Bali. Masing-masing memang bisa memicu gempa dengan magnitud 8,5.

Apa yang harus dilakukan?

Perkembangan ilmu pengetahuan saat ini belum mampu memberikan kemampuan bagi manusia untuk meramal gempa. Pada saat yang sama, penelitian tentang beragam patahan penyebab gempa serta yang terkait masih terkendala dana. Di tengah situasi itu, apa yang harus dilakukan?

Widjo menuturkan, saat ini masyarakat bisa melakukan penyesuaian setelah mengetahui bahwa dirinya tinggal di lokasi rawan gempa. "Misalnya bangunan rumah dibuat tahan gempa," ungkap Widjo.

Sementara, Irwan mengatakan, informasi adanya ancaman seharusnya sudah cukup bagi pemerintah dan masyarakat untuk memulai perubahan.

"Warga harus lebih waspada, edukasi yang diberikan pemerintah ke masyarakat terus dilakukan, institudi pendidikan juga harus mulai membangun kesadaran tentang gempa," jelas Irwan.

Terkait adaptasi yang bisa dilakukan warga, peneliti dari Pusat Penelitian Geoteknologi LIPI, Eko Yulianto, saat ditemui Desember 2013 lalu menuturkan perlunya warga memiliki ruang aman untuk berlindung saat gempa.

Ruang aman bisa berupa ruang atau sudut mana pun di dalam rumah yang dibangun  tahan gempa. Strategi ini merupakan alternatif ketika membangun rumah tahan gempa masih sulit. Badan Nasional Penanggulangan Bencana (BNPB) perlu mengampanyekannya.

V, Karena Dari Laut Selatan Mengirim Sinyal Ancaman Gempa

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.

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.
