Abstract

Limbah cair mengandung berbagai jenis senyawa kimia berbahaya yang dapat menyebabkan pencemaran lingkungan seperti logam berat Zn, Pb, Cu, Cr, Cd, Co,Fe, Mn, Ni, Hg, dan As. Oleh sebab itu perlu dilakukan pengolahan limbah terlebih dahulu sebelum dibuang ke badan air. Pengolahan limbah cair yang dapat dilakukan yaitu dengan metode biosorpsi, karena lebih efisien dan ekonomis. Tujuan dari kajian ini yaitu untuk mengetahui pemanfaatan daun teh sebagai biosorben untuk menyerap logam berat dalam air limbah. Dalam penelitian ini digunakan metode biosorpsi menggunakan biosorben ampas daun teh tanpa perlakuan, serta teraktivasi dan termodifikasi zat kimia. Hasil dari kajian ini didapatkan biosorben ampas daun teh tanpa perlakuan mampu menyerap logam berat Zn, Pb, Cu, dan Cr dengan efisiensi penyerapan 59,46 – 99,7 %, biosorben ampas daun teh teraktivasi dan termodifikasi zat kimia mampu menyerap logam berat Zn, Cd, Co, Pb, Cu, Fe, Mn, Ni, Cr, Hg, dan As dengan efisiensi penyerapan 68,68 – 100%

Abstract

Salah satu industri yang perlu mendapat perhatian adalah usaha industri sarung tenun. Industri ini menghasilkan limbah cair yang dihasilkan dari proses pewarnaan. Pembuangan limbah secara sembarang akan menimbulkan dampak merugikan bagi lingkungan. Oleh sebab itu perlu dilakukan pengolahan limbah terlebih dahulu. Tujuan dari penelitian ini untuk menurunkan kadar COD dan TSS pada limbah cair warna industri sarung tenun. Penelitian ini menggunakan metode adsorpsi menggunakan adsorben Zeolit teraktivasi asam sulfat. Konsentrasi Asam Sulfat yang digunakan adalah 2,5 N. Persen removal COD terendah dengan massa zeolit sebesar 1 gram dengan waktu 60 menit sebesar 30,98% dan  persen removal COD tertinggi dengan massa zeolit sebesar 5 gram dengan waktu 180 menit sebesar 59,61%. Persen removal TSS terendah dengan massa zeolit sebesar 1 gram dengan waktu 60 menit sebesar 74,16% dan persen removal TSS tertinggi dengan massa zeolit sebesar 5 gram dengan waktu 180 menit sebesar 94,05%. Kata kunci: Zeolit, Adsorpsi, Limbah industri warna sarung tenun

Abstract

Ethanol gel is a semisolid fuel made from ethanol by mixing the gelling agent.Ethanol gel has the advantage of facilitating packaging, distribution and storagebecause it does not spill and flow easily. Another advantage of ethanol gel is that itdoes not smoke during the combustion process, does not cause soot and does notproduce harmful gases. This research aims to compare the 2 best gelling agentsand study the effect of adding the gelling agent to the calorific value. The processof making ethanol gel begins by inserting a gelling agent of 4-12% w into a beakerglass. Then add 20 ml of distilled water while stirring until the solution thickens.After that, slowly put 75 grams of 95% ethanol into the beaker which alreadycontains the gelling agent solution. For the manufacture of ethanol gel with astearic acid gelling agent, heating is done first in making the solution and left for 3hours after mixing with ethanol. Based on the analysis, it was found that thehighest calorific value was 12052.7 cal / g with stearic acid gelling agent in theaddition of 12% (% w).

Abstract

Research on the manufacture of bioplastics from bran is one of the efforts todevelop the development of environmentally friendly plastics because they can bedecomposed by microorganisms. In addition, this study also seeks to reduceenvironmental pollution due to the disposal of rice mill waste. The research wasconducted by mixing rice bran with water, sulfuric acid and sorbitol in variousvariations of the ratio of sorbitol and bran 1:10; 2:10; 3:10; 4:10 and 5:10 (v:b).Furthermore, chitosan was added as a reinforcement with variations in theaddition of chitosan with bran, namely 4:10; 6:10; 8:10; 10:10 and 12:10 thenprinted and analyzed for dance strength, swelling and surface morphology. Thetest results showed the highest tensile strength value in the ratio of sorbitol andbran 5:10 and chitosan bran 10:10 with the highest tensile strength value of 64.27MPa and 25% swelling value. Surface morphology shows an uneven and hollowsurface.

Abstract

The liquid waste produced by the food coloring industry contains quite dense colors, so it needs to be processed before being discharged into the environment. The study aims to determine the effect of aloe vera coagulant doses on removal, to determine the effect of activated carbon on color removal. Liquid waste is waste or residue from an activity or business that is in liquid form and contains various kinds of materials that can pose a hazard to water if disposed of immediately. The research method consisted of making aloe vera solution followed by coagulation using aloe vera solution and adsorption of color waste using activated carbon. The results showed that the addition that produced the highest color removal in the coagulation process was 1.2% coagulant dose. The mass of activated carbon which produced the highest removal was 62.5% with a removal of 95%.
