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.

Abstract

Sempan Village is one of the villages in Pemali District of Bangka Regency, Bangka Belitung Islands which do not yet have the featured products, while this village has nipah plants that are not used optimally. The nipah fruit can be further processed into a featured product of village i.e. syrup. The service program Chemistry Department is training Sempan Village society on the manufacture of syrup from nipah fruit. The method of this activity includes three stages i.e. preparation, implementation and evaluation. After this activity is carried out, the Sempan Village society have increased understanding, knowledge and motivation in utilizing nipah fruit into processed syrup products and this product is expected become one of the featured products of Sempan VillageKeywords: nipah fruit, syrup, Sempan Village

Abstract

SMKN 1 Muntok, West Bangka, offers an Industrial Chemical Engineering vocational program that focuses on processing local raw materials into products with economic value. One underutilized local resource is the essential oil of the sapu-sapu plant (Baeckea frutescens L.), which grows abundantly in post-tin mining areas and is known to exhibit antibacterial, antifungal, and anti-inflammatory activities, making it a promising raw material for aromacare products. However, students’ limited knowledge of product formulation and marketing strategies remains a major constraint to its development. This community service activity aimed to enhance students’ knowledge and skills in producing safe, innovative, and competitive aromatherapy and massage oil products based on sapu-sapu essential oil. The methods included socialization of essential oil potential, training in product formulation and packaging in accordance with applicable standards, and digital marketing assistance through social media and e-commerce platforms, involving students from Universitas Bangka Belitung as facilitators. The results showed an improvement in students’ understanding of the potential of sapu-sapu essential oil, as well as their ability to formulate, package, and promote aromacare products. The resulting products had a distinctive aroma and were well accepted based on sensory evaluation. In addition, students began to recognize the importance of digital marketing in enhancing product competitiveness. Overall, this community service activity successfully improved students’ competencies in the production and marketing of aromacare products based on local potential and demonstrated the potential to generate flagship school products that support economic strengthening and student entrepreneurship.
