Abstract

Palm Oil Mill Effluent (POME) is a type of agro-industrial organic originating from the by-products of the processing of fresh fruit bunches (FFB) of oil palm. Palm oil waste pollution decreases environmental quality which will indirectly be harmful to the environment and human health. This research aims to treat palm oil liquid waste using electrocoagulation process, activated carbon filter, zeolite and membrane separation technology in an integrated manner. The combination of palm ash and zeolite was found to be the most effective in reducing pH, TSS, COD, BOD, and fatty oils. The electrocoagulation method best conditions are at a voltage of 15 Volts and an operating time of 90 minutes. The system of integration of the electrocoagulation process, activated carbon filters, zeolite and membrane separation technology has proven to be very effective for processing palm oil mill wastewater. The treatment results meet the quality standards based on Governor of South Sumatra Regulation No. 8 of 2012 concerning Liquid Waste Quality Standards for Industrial, Hotel, Hospital, Domestic and Coal Mining Activities and based on Government Regulation no. 22 of 2021 concerning Implementation and Management of the Environment (Annex 6 National Water Quality Standards) with average results: pH 7.02 TSS 44.6 mg/L, COD 24 mg/L, BOD 2.89 mg/L and fatty oils 1.2 mg/LKeywords: Palm Oil Mill Effluent, Electrocoagulation, Zeolite, UF Membrane, Fatty Oil

Abstract

Food provider at university is one of places that needs to implement standards of food hygiene and sanitation (FHS). This study aimed to evaluate and analyze practices of FHS based on Regulation of Health Minister No. 1098 of 2003 and best practices in six food providers at University X. This study used mixed method evaluation with sequential explanatory design through two stages. Stage I was in forms of assessment on six food providers, food handlers and laboratory examination on food and beverage samples as well as on eating utensils. Stage II was in form of focus group discussion (FGD) to deepen findings at stage I. Results of this study showed that 100% of food providers had not yet met the government’s regulation. As much as 67% of eating utensils and 83% of food were contaminated with bacteria. Based on food handler examination results, 100% of food handlers were not yet to get medical checkups and training. FGD results indicated that findings at stage I were associated with a lack of knowledge among food handlers and the absence of special unit to oversee FHS at campus. In conclusion, six food providers in the study area have not met the regulation.

Abstract

Bodyscrub merupakan produk kecantikan yang sangat bermanfaat untuk mengangkat sel-sel kulit mati. Penumpukan  limbah rumah tangga seperti kulit buah dan sayur dapat bermanfaat jika diolah menjadi eco-enzyme. Eco-enzyme sendiri merupakan produk hasil fermentasi dari limbah buah-buahan dan sayuran yang memiliki banyak manfaat.  Penelitian ini bertujuan untuk mengetahui formulasi bodyscrub yang terbaik dari variasi 80%, 50%, dan 20% eco-enzyme, 9 gram, 8 gram, 7 gram asam stearat; 0,5 gram; 1 gram; 1,5 gram ekstrak daun ketumbar, dan 1,5 gram; 2,5 gram; 3,5 gram biji apricot. Dilakukan pengujian yaitu uji pH, uji organoleptik, uji daya sebar, uji homogenitas, dan uji iritasi. Hasil pengujian pH  didapatkan hasil 6,7-7,1 dan daya sebar terbaik yaitu sampel X3 sebesar 4,275 cm. Pengujian iritasi terbukti tidak munculnya gejala eritema dan edema. Setelah uji coba didapatkan penggunaan 9 gram asam stearat menghasilkan sediaan bosyscrub yang paling kental. Pemakaian biji apricot terbaik yaitu 3,5 gram untuk 50 gram sediaan karena saat diaplikasikan bulir nya tidak terlalu kasar dan teksturnya paling baik. Kesimpulannya bahwa formula Z3 dengan 9 gram asam stearat dan 3,5 gram biji apricot memiliki formula terbaik karena teksturnya yang paling kental dan pas ketika diaplikasikan ke kulit, serta tidak membuat iritasi.
