PERENCANAAN BANGUNAN INSTALASI PENGOLAHAN AIR LIMBAH (IPAL) PABRIK KARET PTPN XII KEBUN GLANTANGAN MENGGUNAKAN BIOFILTER ANAEROBAEROB TERCELUP

Abstract

Abstract, The plantation rubber processing plant is located in Jember Regency and has an area of 23,271.30 m2. In the process of treating liquid waste water from the PTPN XII rubber factory, the Glantangan plantation is only carried out with several tubs that function as filters to accommodate the liquid waste that is wasted from the results of rubber processing. The resulting liquid waste contains organic matter with high levels of BOD and COD. Based on these problems, it is necessary to design a wastewater treatment plant (WWTP) so that the wastewater discharged into water bodies meets quality standards. The planning is based on the characteristics of the wastewater obtained from the results of laboratory tests and the existing conditions of the study site which aims to determineIPAL building design, Bill of Quantity (BOQ) the required and Budget Plan (RAB). The planned alternative technology is treatment with Immersed Anaerobic-Aerobic Biofilter technology. Based on the calculation of Engineering Design (ED), the results obtained are the dimensions of the Equalization Tank (4.8 m x 2.4 m x 2.5 m), Initial Precipitation Tank (2.0 m x 1.0 m x 2.5 m), Anaerobic Biofilter Bath (3.4 m x 1.7 m x 2.5 m), Aerobic Biofilter Body (3.4 m x 1.7 m x 2.5 m), Final Settlement Body (2.0 m x 1.0 m x 2.5 m). The cost required for the construction of the WWTP is Rp. 770,9000,000.00.
