Abstract

ABSTRAKNata de coco adalah salah satu produk makanan yang memanfaatkan air kelapa. Produksi industri nata de coco di Indonesia masih banyak menghasilkan limbah cair yang mengandung bahan organik  yang mengakibatkan kandungan air berubah. Bertambahnya industri nata de coco baik dalam skala kecil (industri rumahan) dan skala besar (industri pabrik) menimbulkan dampak meningkatnya hasil limbah cair nata de coco. Adsorben yang dipilih antara lain krikil, serabut kelapa, zeolite, kain, dan spon. Sedangkan variasi tegangannya adalah 5, 10, 15 volt serta untuk waktunya yaitu 10, 30, 45, 60, dan 75 menit. Hasil penelitian ini diperoleh efektivitas sebesar 34,01% untuk kandungan BOD dan 14,29% untuk perubahan suhu. Kata kunci : BOD; elektrolisis; limbah cair; nata de coco; pipe filter layer; suhu ABSTRACT Nata de coco is a food product that uses coconut water. The production of the nata de coco industry in Indonesia still produces much waste containing organic material, which causes the water content to change. The increase in the nata de coco industry on a small scale (home industry) and a large scale (factory industry) impacts of the liquid waste product of nata de coco. The adsorbents selected were gravel, coconut fiber, zeolite, cloth, and sponge. While the voltage variations are 5, 10, 15 volts and the time is 10, 30, 45, 60, and 75 minutes. This study’s results have the highest rights of 34.01% for the BOD content and 14.29% for temperature changes.

Abstract

Cassava contains hydrocyanic acid (HCN) derived from the hydrolysis process cyanogenic glucoside (linamarin and lotaustralin) by endogenous enzymes that are marked in blue on cassava. Production of cassava chips contained in Donohudan, Surakarta very abundant with a turnover of 10 tons each month so that the production process produces some waste that has no economic value. Wastewater from the washing of cassava chips can be a serious problem if not treated properly. Mechanical installation of pipe filter layer may be one alternative to resolve these problems .. This technique uses a combination of natural adsorbent with terraced flowed into the pipe. The adsorbent used include gravel, sepet (coconut fiber), silica sand, zeolite. The parameters examined in this study is the analysis of the levels of COD (Chemical Oxygen Demand) and TSS (Total Solid Suspended) in the wastewater industry cassava chips. Data collection was performed by calculating the COD and TSS levels before and after processing with pipe filter layer. Based on data obtained optimum pH value accordance with the standard of food waste that is 7.89. For COD and TSS, the optimum value changes occurred on respectively of 99.5% and 99.7%. Mechanical pipe filter layer effectively handle the wastewater industry cassava chips
