Jembatan Tol Cisomang Diupayakan Tidak Dirombak Ulang
01.08TEMPO.CO, Bandung - Anggota Komite Keselamatan Jembatan dan Terowongan Jalan Raya yang dibentuk oleh Kementerian Pekerjaan Umum dan Perumahan Rakyat, Masyhur Irsyam mengatakan, kondisi Jembatan Cisomang di ruas tol Purwakarta-Bandung-Cileunyi (Purbaleunyi) masih bisa diperbaiki. “Targetnya dilakukan perkuatan untuk memenuhi kriteria teknis seperti keadaan semula,” ujar pakar geoteknik dari Fakultas Teknik Sipil dan Lingkungan ITB itu, Ahad, 1 Januari 2017.
Menurut Masyhur, tahapnya mencakup langkah cepat untuk perbaikan atau perkuatan jembatan sementara. Adapun perbaikan atau perkuatan secara permanen, ditujukan pada fondasi maupun pilar yang mengalami pergeseran.
Sementara ini, kata Masyhur, langkah cepat penanganan antara lain, pengamatan kondisi pilar jembatan dan fondasi secara ekstra ketat, penguatan pilar, pemasangan alat-alat instrumentasi mekanika tanah seperti inclinometer dan piezometer, serta pemindaian profil tanah di sekitarnya.
“Konstruksi diatas tanah clay shale masalah utamanya biasanya adalah pergerakan tanah. Di bidang Rekayasa Geoteknik, kalau kita ketemu Clay Shale seperti ketemu penyakit kanker,” katanya. Kondisi yang serupa misalnya pada ruas jalan tol lain seperti Semarang-Bawen dan di daerah Hambalang, Bogor.
Merombak ulang jembatan, kata dia, merupakan pilihan yang dihindari karena berdampak besar pada jalur lalu lintas dan bukan pilihan yang optimal.
Rencananya, pada awal Januari ini, komite bersama Direktorat Jenderal Bina Marga, Jasa Marga dan Badan Pengelola Jalan Tol akan mengadakan pertemuan untuk membahas hasil pengamatan dan penyelidikan tanah dan beton guna mempertajam solusi perbaikan dan perkuatan.
Direktur Jembatan, Direktorat Jenderal Bina Marga, Kementerian Pekerjaan Umum dan Perumahan Rakyat, Hedy Rahadian pada Selasa lalu menyebutkan, Jembatan Cisomang di KM 100+700 mengalami pergeseran maksimum 57 sentimeter, tepatnya di pilar 2. Jembatan itu berada di wilayah Desa Tenjolaut, Kecamatan Cikalong Wetan, Kabupaten Bandung Barat.
Pergeseran itu diketahui setelah PT Jasa Marga melaporkan adanya retakan di salah satu tiang Jembatan Cisomang. Akibatnya, pengguna akses dibatasi hanya untuk golongan I atau mobil hingga bus. “Rencana perbaikan selama tiga bulan, ditargetkan bisa juga kurang untuk menaikkan sefety factor sesuai persyaratan teknis,” kata Masyhur.
Dia menepis anggapan bahwa insiden jembatan tol tersebut akibat perencanaan pembangunan dan pelaksanaan konstrukai yang kurang memadai. Semua kaidah teknis, baik dari kaidah rekayasa geoteknik maupun dari kaidah rekayasa struktur, sudah dipenuhi saat pembangunan sehingga memenuhi kriteria desain. Selain itu, menurut Masyhur, saat pelaksanaan pun sudah disupervisi oleh konsultan supervisi.

Riau Pulp and Paper Jadi Produsen Kertas Terbesar Kedua di Dunia
22.37Industry.co.id-PT Riau Andalan Pulp and Paper memastikan sebagai perusahaan kertas berskala terbesar di dunia. Hal tersebut direalisasikan setelah perseroan meresmikan pabrik ketiganya di Pangkalan Kerinci, Kabupaten Pelalawan Riau.
“Pabrik baru ini sudah mulai diujicoba dan diharakan mulai berproduksi Januari tahun depan,” kata Asisten Manajer Komunikasi PT RAPP, Rabu (16/11/2016).
Ia mengatakan, sebelumnya RAPP sudah memiliki dua pabrik kertas dengan total kapasitas produksi 3.500 ton per hari atau sekitar 850 ribu ton per tahun.
Dengan selesainya pembangunan pabrik ketiga, kapasitas produksi kertas di pabrik milik RAPP nantinya akan mencapai 1,1 juta ton per tahun. Angka ini menjadikan mereka sebagai produsen kertas terbesar kedua di dunia setelah International Paper, produsen kertas asal Amerika Serikat.
Dari pabrik yang mereka miliki saat ini, RAPP memproduksi tiga jenis kertas, yakni customer roll, cut size, dan folio. Tiga jenis kertas itu sebagian dipakai untuk memenuhi kebutuhan dalam negeri dengan mereka Paper One, dan sebagian lain diekspor ke 75 negara, antara lain Jepang, Australia, negara-negara di Asia Pasifik, dan Timur Tengah.
Budhi mengatakan, selain memproduksi kertas, RAPP juga menghasilkan pulp atau bubur kertas yang produksinya mencapai 1,2 juta ton per tahun. Angka ini menjadikan RAPP sebagai produsen pulp terbesar ke-9 di dunia. “Secara persentase, RAPP men-supply sekitar 7 persen kebutuhan pulp di dunia,” kata Budhi.
Dari produksi 1,2 juta ton pulp itu, RAPP memakai sekitar 20 persen untuk memproduksi kertas di pabrik milik mereka sendiri. Sementara sebagian besar lainnya diekspor ke lebih dari 20 negara, terutamanya ke Tiongkok.
“Ke depannya kami akan fokus di sektor hilirisasi, sehingga kemungkinan produksi pulp itu akan lebih banyak dimanfaatkan di pabrik kertas milik RAPP sendiri,” ujar Budhi Firmansyah.

GE Manfaatkan Teknologi Digital Industri Blok Migas
19.35Ia berpendapat dengan digitalisasi industri minyak dan gas, operator juga dapat mengetahui kondisi 'kesehatan' alat-alat yang dimiliki kapan pun dan di mana pun. Dia berkeinginan Indonesia Timur dapat menjadi daerah digitalisasi.
"Jadi mudah-mudahan Indonesia, Indonesia Timur bisa (menggunakan digital industri)," kata Iwan.
Dikatakannya, pada saat ini, GE lebih memilih untuk meningkatkan produktivitas sumur-sumur yang sudah ada ketimbang membuka sumur baru. Apalagi di tengah harga minyak rendah yang dapat menyebabkan perusahaan minyak mengalami kerugian.
Peningkatan produktivitas sumur minyak pun dilakukan dengan memanfaatkan industri teknologi digital. Salah satunya berupa pompa electric dengan daya analisis canggih. Dengan pompa tersebut pengangkatan minyak di sumur dilakukan secara otomatis setelah penuh.
