Abstract

This study aims to design an Anaerobic Up Flow Filter system processing tool. This tool is used to analyze the liquid waste of tofu industry which is used to determine differences in levels of BOD, COD, and SS before and after processing. This tool is also used to determine the effect of variations in processing debit and processing capability of the Anaerobic Up Flow Filter system on decreasing levels of BOD, COD, and SS according to applicable quality standards. The collection of tofu wastewater used the method for a moment in dry season. Verification of processing results is carried out at Environmental Engineering Laboratory of IST AKPRIND Yogyakarta. BOD levels after processing on all filter media were still above the quality standard threshold according to DIY Governor Decree No. 281 / KPTS / 1998. While the levels of COD and SS in activated charcoal filter media are still above the quality standard threshold according to DIY Governor Decree No. 281 / KPTS / 1998. The design of this tool produced a significant difference, namely the effect of discharge variation on Anaerobic Up Flow Filter processing are BOD 90.13%, COD 95.81% and SS 88.53%. The filtered sand and gravel media results result in meeting the quality standards, but for filter media the activated charcoal has not met quality standards.

Abstract

The south coast of Java area which is known as barrend land and has no economic value for agricultural land, this area has big potential for aquaculture like shrimp farm, and from 2001 pilot project shrimp farm expanded to two districts in Central Java namely Kebumen Districts and Purworejo Districts (Dwi, 2017). Based on data from Kebumen Regional Agency for Integrated Licensing Services Investment Board, in 2016 there were 300 shrimp farms scattered in several sub-districts and villages (http://www.kebumenekspres.com/2016/).As one of the activities in the coastal mainland, pond fishery management are often lack of attention about natural resources capabilities with preservation of ecosystems and environment (Yustiningsih, 1996, dalam Libriyanto, 2008). Feeding rate used in shrimp ponds generate organic waste that can pollute the aquatic system (Hongsheng et al, 2008 dalam Fahrur et al, 2016).According to the Decree of the Minister of Maritime Affairs and Fisheries No: Kep. 28/MEN/2004 about general instruction shrimp cultivation in ponds, some parameters that require management BOD, NH3 dan PO4. The planned processing alternatives in this pre-designed consist of Sequencing Batch Reactor, anaerobic biofilter,basin of water collectors that functions as well chlorination tub and mud dryer tub. The test results of characteristics of shrimp pond wastewater parameters BOD5 : 152,87 mg/L, NH3 : 25,25 mg/L , PO4-3 : 1,0578 mg/L with processing capacity 325 m3/day requires land area 232,41 m2 and Calculation of the cost budget plan based on the price of the work unit (HSPK) Kebumen Region 2016 generate a total cost of Rp. 328.951.329,-
