Abstract

Kadar asam lemak bebas (FFA) minyak yang tinggi dalam proses pembuatan biodiesel menyebabkan terjadinya reaksi saponifikasi yang akan berakibat pada penurunan kadar FAME (fatty acid methyl ester). Kadar FFA yang tinggi dapat diturunkan dengan mereaksikan minyak dengan metanol dengan bantuan katalis asam H2SO4 yang lebih dikenal dengan reaksi esterifikasi. Pada reaksi esterifikasi didapatkan kondisi optimal waktu reaksi 120 menit dengan temperatur reaksi suhu 60°C dengan penggunaankatalisH2SO4 sebanyak 5 ml. Pada kondisi ini kadar FFA dapat diturunkan 80% dari kadar FFA awal minyak

Abstract

The production of biodiesel from waste cooking oil as an effort to reduce environmental pollution and it’s production cost . Free fatty acid content is high on used cooking oil is required twice in the biodiesel production process, namely the process of esterification and transesterification. The success is determined by the transesterification reaction temperature, reaction time, the rotation speed of the stirrer, the catalyst, the molar ratio of methanol, a type of alcohol, FFA content material; and the moisture content of materials. In this research study ditekannkan the transesterification process, especially changes in temperature (50oC, 55oC, 60oC, 65oC, and 70 oC) and time (30,60,90, and 120 minutes) to yield the amount of biodiesel. The results of GC-MS testing on used cooking oil is known that the content of lauric acid and palmitoleic acid contained in the raw material for biodiesel used cooking oil at 0% and 4.6 Wt% Wt, and FFA content of 9.67%. Transesterification optimal temperatures between 60oC to 65oC, capable mengahsilkan biodiesel yield of> 93%. Total yield of biodiesel produced in 30 minutes transesterification reached 80%, and 60 minutes to reach 90%.

Abstract

Greenhouse gas emissions are an environmental issue that has an impact on climate change and global warming. One of the cause is the burning of rice straw after harvest in the field. The existence of majelis taklim is not only religious facilities, and it’s as a way to community empowerment. QS. As-Sad 27 and QS Al-Anbiya 16 explains that everything created by Allah SWT with all aims and benefits. Generally, rice straw is perception as a waste, but if it utilised with science and technology will be able to improve the use of value and economic value. 82,19% and 79,45% of the members of majlis taklim have perception that utilizing of rice straw can improve their income and part of the sustainable environmental management. And 94,25% of the members of majelis taklim did not utilise rice straw and burned it in the field. They did not have skills and knowledge to utilise of the rice straw. Furthermore, training and education must be conducted regularly.

Abstract

ABSTRACTWastewater from sugar industries has complex characteristics and depends on the production capacity. The main aim of this study is to determine the effectiveness of the waste water treatment processes (WWTP) of two sugar factories PG. Kediri and PG. Sidoarjo in reducing pH, BOD, COD, and TSS during year 2016 and 2017. Wastewater influents in both factories exceeded the water quality standards of Ministry of Environment Regulation Number 5 Year 2014. After treatments, water quality parameters of the effluents including pH, BOD, COD and TSS were significantly decreased. The effectiveness of the PG Kediri WWTP in reducing BOD, COD and TSS was 98.52%; 98.47% and 91.51% respectively. The effectiveness of PG Sidoarjo WWTP in reducing BOD, COD and TSS was 5-20% lower than that of PG. Kediri. Keywords: effectiveness performance, WWTP, sugar industry, wastewater  ABSTRAKLimbah cair yang dihasilkan oleh industri gula memiliki karakteristik yang kompleks dan bergantung pada kapasitas produksi. Pengolahan limbah cair dilakukan secara fisika dan biologi untuk mengurangi konsentrasi bahan pencemar yang menjadi permasalahan lingkungan. Tujuan dari penelitian ini adalah untuk mengetahui efektifitas kinerja IPAL di PG. Kediri dan PG. Sidoarjo dalam menurunkan konsentrasi pH, BOD, COD dan TSS selama tahun 2016 dan 2017. Sebelum pengolahan air limbah memiliki konsentrasi tinggi melebihi ambang batas baku mutu air limbah yang ditetapkan oleh Peraturan Menteri Lingkungan Hidup RI No. 5 Tahun 2014. Setelah dilakukan pengolahan terjadi penurunan konsentrasi pH, BOD, COD, dan TSS secara signifikan yang diukur di bagian outlet IPAL. Besarnya efektifitas kinerja IPAL di PG Kediri dalam menurunkan konsentrasi BOD, COD, dan TSS sebesar 98,52%; 98,47%; dan 91,51%. Berbeda dengan nilai efektifitas kinerja IPAL di PG Sidoarjo yang lebih rendah 5 sampai 20% dari efektifitas PG. Kediri.Kata kunci: efektifitas kinerja, industri gula, IPAL, limbah cair
