Abstract

Thorium is an essential element as an alternative nuclear fuel to replace uranium. Thorium is found in the mineral monazite, which is a by-product of the alluvial tin mining process. Many methods have been used to extract and separate thorium from uranium and REEs from monazite, one of which is the organic solvent extraction method. In this research, the primene JMT, which is an extractant of primary amine compounds, was used in the method. The studied parameters are feed pH, JMT primene concentration, and stirring speed. The results show that the optimum conditions for Th extraction in monazite using solvent extraction method primene JMT were obtained at pH 0.5, extractant concentration of 2%, and stirring speed of 300 rpm with Th recovery of 94.05% while U and REE were not extracted.

Abstract

In managing household waste, KSM Srimenanti Jaya has played an active role in supporting the efforts of both the community and the government. Their main services in Kelurahan Srimenanti include waste collection, provision of plant seedlings, and processing of domestic waste. However, until now, no laboratory testing has been conducted on the compost fertilizer they produce, so the quality of the product remains uncertain. Therefore, this community service program is aimed at improving the quality of compost through fertilizer standard certification for KSM Srimenanti Jaya. Based on laboratory test results, most of the compost quality parameters have met the requirements of SNI 19-7030-2004 and are deemed marketable. Nevertheless, some aspects such as pH level, presence of foreign materials, and particle size still need to be optimized. The program also includes outreach on strategies to enhance compost quality, distribution of pocket guidebooks, and the provision of large waste shredding machines. At the conclusion of the activities, an evaluation was conducted which showed that all KSM managers felt greatly assisted and understood the material presented in the program.
