Abstract

Recent reports show a significant global rise in demand for ground coffee, highlighting a trend towards specialty brews. This interest has led to research on coffee's chemical properties that influence flavour. Key characteristics include proximate content, total dissolved solids (TDS), and pH levels. This study examines the chemical traits of ground Robusta and Arabica coffee from the Argopuro area, produced by Teaching Factory Coffes Processing, Politeknik Negeri Jember. This study used Robusta and Arabica coffee processed using natural, wet methods and were roasted at medium to dark levels. The analysis included key parameters: proximate analysis for total moisture and ash content (gravimetric method) and total fat content (Soxhlet method), additionally, pH measurements were taken with a pH meter, and total dissolved solids (TSS) were evaluated using a refractometer. Employing a non-factorial Completely Randomized Design (CRD), the study focused on the two coffee types: Arabica and Robusta Argopuro. Data analysis was rigorously conducted using an independent sample t-test. The findings clearly indicate that the type of coffee has a significant impact on the proximate content: water, ash and fat content and pH levels of the ground coffee, but not significant impact on TDS.

Abstract

The Margi Mulyo farmer group is one of the farmer groups in Wuluhan District, Jember Regency. The high potential for mango production in Wuluhan District is the main background for the implementation of service with the aim of increasing the capacity of human resources in cultivating mangoes to produce mangoes that can meet national and export market standards through the implementation of good agricultural practices (GAP). The main problem that occurs at the activity location is that mango cultivation is still not standardized by members of farmer groups so that the mango fruit produced does not fully meet market standards. Mangoes are only marketed in a slash system so farmers cannot get high returns on the fruit sold. So the high interest in mangoes as national fruit consumption is not accompanied by mango production according to market standards. The method used in this activity is the active participatory method, in three main activities, namely counseling, implementation, and mentoring. This activity was carried out from August to September 22024. The results of the service activity included an increase in the knowledge of members of the Margi Mulyo farmer group regarding the application of GAP, an increase in farmers' ability to apply mango flowering induction and the use of certified seeds.

Abstract

Waste remains a complex environmental issue in Indonesia. Waste is defined as the final by-product of human activities in solid or semi-solid form that is no longer utilized. In 2024, Indonesia generated approximately 35 million tons of waste, with 61.37% remaining unmanaged. The majority of this waste consists of food residues. This community service program aimed to enhance public knowledge and skills in managing food waste for the cultivation of maggot (Hermetia illucens) and its utilization as an environmentally friendly alternative feed source. The main problem faced by the community partner was the suboptimal management of household organic waste, which became the foundation for this educational program. The implementation methods included socialization, technical training on maggot cultivation, demonstration of organic waste processing as maggot media, and mentoring at the household level. The results showed a significant increase of 88% in participants’ understanding of maggot cultivation and its ecological benefits. Furthermore, participants successfully produced maggots independently for use as fish and poultry feed. This activity had a positive impact by reducing organic waste volume, lowering feed costs, and increasing environmental awareness within the community. Therefore, maggot cultivation education proved effective in supporting community-based organic waste management while simultaneously creating new economic value from previously unutilized waste.
