THE PROCESSING OF HOUSEHOLD WASTE INTO VARIOUS TYPES OF LOCAL MICRO ORGANISMS (LMO) LIQUID FERTILIZERS IN PUDAK VILLAGE, KUMPEH ULU DISTRICT, MUARO JAMBI REGENCY. Household waste such as leftover rice and vegetables can be used as a major component in producing Local Micro Organism (LMO). Local Micro Organism has many advantages, including being used as liquid organic fertilizer, as a decomposer in compost processing, as well as being used as bio-pesticides. The purpose of this community service project was to help the people, particularly farmers, in Pudak Village in producing LMO liquid fertilizer by providing them with relevant knowledge and technology. The technology was developed by utilizing of leftover rice and vegetables which are normally treated as unwanted household wastes. This LMO liquid fertilizer is very much needed by farmers to increase their farm output since it was proven to be able to improve plant growth and development, which in turn increase farm production eventually. In addition, this liquid fertilizer can also be sold and resulting in additional income for farmer household, and village community in general. Finally, as is stated in the objective, this community service program has produced output in the form of LMO liquid fertilizer, which then can be applied on farmers’ field.
Mercury is a harmful element that commonly accumulates in the environment through anthropogenic activities such as gold mining. This study aimed to examine the use of palm oil fuel ash (POFA) as an agricultural waste to remove mercury in gold mining wastewater. The technology applied in this study was adsorption and precipitation. POFA was first washed until neutral then mixed with gold mining effluent with time variation of 30, 60, 90 minutes. Next, precipitate it for 30 minutes. The adsorbent dose used in this study was 250 mg with 1 litre effluent. The maximum adsorption efficiency observed in this study was 96.77%. The utilization of POFA as an adsorbent reduced mercury levels in wastewater below the allowed released mercury level to the environment (0.0025 mg Hg/L). Results indicate that reducing mercury from gold mining wastewater by utilizing POFA was simple, effective, and low-cost to be implemented.

Arsenic is toxic element, accumulate in the environment as main contaminant in aqueous waste stream. This study aimed to analyze the capability of raw palm oil fuel ash (pofa) as a potential adsorbent to remove arsenic contamination in the wastewater of mining effluent. Technology applied in this study was adsorption followed by precipitation. The maximum arsenic removal percentage of 100 % and a maximum adsorption capacity up to 0.224 mg/g was discovered.The results indicate that the method for arsenic removal from wastewater using raw pofa was effective, simple and lowcost to apply.
CLEAN WATER PRODUCTION IN RIZQULLAH ISLAMIC BOARDING SCHOOL JAMBI. Pondok Pesantren is an Islamic boarding school where students are learning about Islam as well as science and technologies. Adequate and good quality of facilities and infrastructures are needed to support good teaching and learning process. One of such facilities is clean and healthy water which is important to students and teachers in the Pondok Pesantren. Bad quality of water, either for washing or drinking, will affect students’ concentration in studying. Therefore, our community service project was aimed at improving the quality of water at Ma’had Rizqullah by installing a clean water system using multilevel filtration method. The water to be processed was ground water collected from bore wells in Pondok area. By this technology, the requirement of clean water in Ma’had Rizqullah can be met, al can also supply water needs for community around the Pondok. The product of this technology was clean water that can be used for daily activities by students and teachers living in Pondok and surrounding people.
