TERAS JURNAL Vol 1, No 1 (2011): Teras Jurnal, Vol.1, No.1, Maret 2011
Publisher : UNIVERSITAS MALIKUSSALEH

Kegagalan struktur beton pada baja tulangan khususnya di lingkungan laut sering terjadi akibat korosi. Korosi pada baja berkibat rusaknya struktur beton. Kegagalan yang terjadi akibat korosi ini diawali dengan perusakan selaput pasif protektif. Pemicu pelarutan selaput pasif protektif disebabkan penetrasi ion-ion agresif dan oksigen terlarut. Produk korosi yang mungkin terbentuk FeOOCl, Fe3O4, Fe2O3, dan FeO dan berakibat desakan ekpansif terhadap selimut beton. Pencegahannya harus dilakukan saat perencanaan pembentuk struktur beton baja tulangan yang lebih matang, dan pengendalian saat struktur terpasang dilakukan dengan proteksi katodik.Kata kunci : Baja tulangan, korosi, selaput pasif, ion agresif, proteksi katodik

Varietas Mutiara 3 merupakan salah satu varietas unggul kedelai yang dihasilkan melalui teknik mutasi radiasi. Pengembangan varietas kedelai unggul nasional harus didukung oleh teknologi pemupukan seperti pemanfaatan teknologi pupuk hayati. Penggunaan pupuk hayati rhizobium perlu memperhitungkan aspek kesesuaian antara bakteri Rhizobium yang diaplikasikan dengan varietas tanaman kedelai. Penelitian ini dilakukan untuk mengetahui pengaruh kombinasi rhizobium dan mikroba pelarut fosfat terhadap tanaman kedelai varietas Mutiara 3. Seleksi isolat rhizobium dilakukan dengan melihat pola dan kecepatan tumbuh dalam media manitol ekstraks khamir, dan menguji secara invivo pada tanaman kedelai. Pengujian mikroba pelarut fosfat dilakukan dengan mengukur kelarutan P pada media cair Pikovskaya dengan metode fosfat biru molibdate. Hasil penelitian menunjukkan bahwa dari empat jenis isolat, bakteri Rhizobiumisolat R1 sesuai untuk kedelai varietas Mutiara 3, dan secara signifikan meningkatkan bobot kering tanaman sebesar 19.75% dan serapan N sebesar 25.88% dari kontrol. Mikroba pelarut fosfat FPF4 mampu meningkatkan kelarutan P paling tinggi dalam media cair Pikovskaya sebesar 51.13 kali dari kontrol. Kombinasi Rhizobium dan mikroba pelarut fosfat mampu mengurangi kebutuhan pupuk kimia sebesar 50%. Selain itu kombinasi rhizobium isolat R1 dan mikroba pelarut fosfat isolat FPF4 mampu meningkatkan bobot kering tanaman kedelai sebesar 41.67% dan serapan N sebesar 196.47% dari kontrol.

Di Desa Kedung Dalem, Pasar Kemis, Tangerang, terdapat sebuah industri rumahan yang memproduksi bagian atas sandal wanita. Saat ini proses produksinya masih menggunakan alat yang sangat sederhana, seperti palu, mata pelubang dan mata press. Para pekerja yang semuanya wanita mengeluhkan proses pelubangan dan pengepresan cukup melelahkan karena masih dikerjakan secara manual menggunakan palu. Selain itu pekerjaan dilakukan sambil duduk di lantai karena belum ada meja dan kursi kerja. Oleh karena itu, untuk meningkatkan produktivitas dan memperbaiki postur pekerja, maka pada penelitian ini akan dibuat sebuah stasiun kerja yang terdiri dari meja dan kursi kerja serta alat bantu untuk proses pelubangan dan pengepresan bagian atas sandal wanita. Untuk proses perancangan meja, kursi dan alat bantu digunakan metode quality function deployment (QFD). Setelah stasiun kerja dan alat bantu dibuat, dilakukan uji coba dan hasil produksi pelubangan dan pengepresan meningkat dari sebelumnya 84 pasang/jam menjadi 128 pasang/jam atau meningkat sebesar 52,4%. Selain itu, dengan adanya stasiun kerja dan alat bantu, diharapkan dapat mengurangi risiko cedera musculoskeletal pada pekerja, karena skor RULA(Rapid Upper Limb Assessment) dengan menggunakan stasiun kerja tersebut turun dari sebelumnya 7 menjadi 3.Kata kunci: stasiun kerja, alat bantu, produktivitas, QFD, RULA
