Abstract

Kegiatan pickling merupakan proses pencucian pipa stainless steel untuk menghilangkan zat pengotor yang menempel pada pipa. Larutan pickling terbuat dari zat asam, sehingga hasil akhir dari kegiatan pickling menghasilkan limbah yang disebut water rinse. Water rinse masih bisa di buang ke badan air IPAL kawasan industri, asalkan memenuhi baku mutu. Penggunaan metode netralisasi dan presipitasi dengan menggunakan agent Ca(OH)2 sebesar 0.56 kg/hari untuk kapasitas 1 bak water rinse dengan volume 2.043 m3 mampu memberikan presentase removal Fe sebanyak 100%, Cr 100%, dan Ni 99.99%. Dimana dalam metode tersebut mengahsilkan lumpur atau sludge sebanyak 574.10 gram tiap hari yang mengandung logam berat.

Abstract

Mandangin Island is one of the islands in Sampang Regency which has an area of 1650 km 2 with a population of around 3000 people. Most of the people on this island, the majority of whom work as fishermen, generally travel around 12.2 km to Sampang City to buy daily necessities by boarding traditional wooden boats at the Tanglok Sampang port. According to information conveyed by the Head of the Sampang Regency Transportation Service, most or almost all of the passenger ships that dock at Tanglok Port are traditional wooden ships whose actual function is to transport goods, not passengers, which are quite old. The Transportation Department considers the existing ships to be less safe and comfortable and therefore require refreshing. Besides that, wood as the main material in nature is decreasing in quantity so the price is increasingly expensive. The method implemented in this community service is to carry out a fiber glass boat operational training program for traditional boat operators. With this activity, it is hoped that the continued use of fiber glass boats can begin to be used and reduce the use of wooden boats which are relatively more expensive.
