Abstract

PT Bridgestone Kalimantan Plantation (PT BSKP) merupakan agroindustri yang bergerak dalam bidang pengolahan karet berupa RSS (Ribbed Smoked Sheet), menghasilkan limbah terutama limbah sludge dari Instalasi Pengolahan Air Limbah (IPAL).Potensi limbah sludge IPAL PT BSKP sebesar 0,1 m3/hari. Penelitian ini bertujuan mengetahui karakteristik limbah sludge serta fisik-mekanik bata beton, sehingga diperoleh komposisi campuran terbaik limbah sludge IPAL PT BSKP sebagai bahan substitusi pembuatan bata beton. Penelitian pemanfaatan limbah sludge IPAL PT BSKP yang mengandung 1,58% CaCO3 dan 3,21% SiO2, dilakukan sebagai bahan substitusi pembuatan bata beton dengan memvariasikan komposisi agregat (limbah sludge : pasir). Komposisi limbah sludge terhadap pasir adalah 100 : 0, 80 : 20, 60 : 40, 40 : 60, 20 : 80, dan 0 : 100 (% volume), dengan waktu: 7, 14, 21 dan 28 hari.  Hasil penelitian menunjukkan bata beton dengan campuran 1 PC : 4 Agregat  tidak memenuhi bata beton sesuai SNI 03-0349-1989 tentang bata beton untuk pasangan dinding. Setelah dilakukan penelitian terukur dengan analisa grafik didapatkan perkiraan yang memenuhi standar SNI, dengan range komposisi antara 5% - 16% limbah sludge. Sehingga diasumsikan dapat mencapai standar kuat tekan bata beton minimal 25 kg/cm2 . Penelitian terhadap aspek lingkungan menunjukkan limbah sludge aman dimanfaatkan ditinjau dari uji TCLP dan LD50.

Abstract

This paper discusses the handling of slope sliding occured in the segment of Bambangan – Aji kuning East Borneo. The slide occurs because of unprotected slopes and soil types in the form of silt sandy. Treatment methods cantilever retaining walls was designed inorder to handle the sliding. The cost of the this method was also calculated to obtain the price.Soil investigation and topography data were collected as a secondary data. The design was commenced by preliminary design for this method. The next step was continued with the calculation of safety factor of sliding, overtuning, and bearing capacity. For cantilever, the design was included the calculation of reinforcement. Overal stability of slope was performed using Plaxis Professional 8.2. The cost analysis was performed using Bina marga 2010 method.By using the cantilever, the dimension of the pedestal are 3m wide, 0.5 m thick matsand wall and 5m high. the safety factor of overal stability for both method was higher than that of caltilever wall.. The cost of the reinforcement using cantilever Rp 489.373.268,.
