Abstract

Aceh is known for its abundant fishery resources, particularly tuna, which has an annual production of 7,903 tons. However, tuna is highly perishable, necessitating effective preservation methods to maintain its quality. Keumamah fish, a traditional Acehnese dish, is renowned for its dried texture, allowing it to be stored for extended periods and making it a common choice for various events. Objective: This study aims to identify lactic acid bacteria (LAB) present in keumamah fish that contribute to the fermentation process and serve as potential sources of natural antibiotics to inhibit the pathogenic bacteria Escherichia coli. Method: Lactic Acid Bacteria (LAB) isolation was conducted using dilution and inoculation techniques on MRS agar media supplemented with CaCO3. The results indicated that the inhibition zones of the isolated LAB were as follows: isolate IK4 showed an inhibition zone of 9.81 mm, isolate IK5 exhibited 11.3 mm, isolate IK6 had 9.4 mm, and isolate IK9 displayed 10.56 mm. Based on Gram staining and biochemical tests (temperature, pH, and salt tolerance), seven isolates were classified into three genera: Lactobacillus (IK3, IK5, and IK7), Enterococcus (IK4, IK6, and IK9), and Leuconostoc (IK8).

Abstract

The processing of coffee cherries yields unused fruit skin waste, which can be transformed into valuable vermicompost. Vermicompost, which is generated through the process of introducing earthworms such as Eisenia foetida, incorporates vital macro- and micronutrients alongside plant growth regulators. A pre-survey revealed several issues faced by partners: (1) Neglected potential of coffee pod waste area, (2) Fertilizer challenges among horticultural, chili, and shallot farmers, (3) Limited knowledge about coffee pod skin composting as organic fertilizer, and (4) Inadequate cultivation management leading to unprofitable outcomes. To address these challenges, the Community Service Team collaboratively agreed with partners to: (1) Provide counseling on utilizing Eisenia foetida-inoculated coffee waste as vermicompost organic fertilizer, (2) Enhance horticultural farmers' understanding to reduce excessive inorganic fertilizer use, (3) Pilot coffee waste vermicompost application in intercropped chili and shallot cultivation, and (4) Establish coffee waste vermicompost packaging as a farmer group business venture. The achieved outcomes include: First, partner farmer groups received counseling on vermicompost production using Eisenia foetida worm inoculation. Second, partners significantly improved their vermicompost production proficiency. Third, demonstration plots successfully showcased chili and shallot cultivation using vermicompost. Fourth, partners effectively produced vermicompost, leading to a 20% reduction in production costs. Finally, partners were inspired to actively produce and apply vermicompost in their intercropped chili and shallot cultivation, reflecting positive motivation and progress.

Abstract: The province of Aceh has a wealth of local varieties, such as Aceh's local rice, which comes in various types and plays a crucial role in human life. Therefore, it needs to be managed and utilized in a sustainable, harmonious, and balanced manner for the greatest prosperity of the people. The conservation and utilization of the Aceh Sambay Simeulue local rice germplasm have been successfully carried out through systematic field surveys, coordination with the government, and community outreach. The tested Sambay Simeulue rice has yielded 20 pure lines in the early generation. Socialization, conservation, and rice breeding activities have produced candidates for new superior varieties, which have been implemented on Simeulue Island. The new superior rice lines resulting from the selection process exhibit promising characteristics, including productivity reaching 8 tons/ha and excellent rice taste. As a result, the utilization of Sambay Simeulue superior rice has been enhanced by increasing support for the supply of superior varieties through partnerships. Additionally, efforts have been made to strengthen seed institutions for large-scale production. By optimizing seed production on a wider scale, the use of quality seeds from superior varieties, produced through community service, can be further increased.
