Abstract

Cascara are side material that resulting from grinding the coffee beans. Cascara can be processed into refreshing herbal tea contain high nutrition level and it has profitable economic value. Women Farmers group (KWT) Elong Tuna located in Lantan Village, North Batukliang District Central Lombok Regency are only considered that cascara is just a waste material and not utilized to lack of knowledge and information about how to processed it. This community service activity (PkM) was aim to give education and information about benefits of cascara as well as providing training on how to process cascara into herbal tea. The method used in this Community Service Program (PkM) is socialization with presentations, discussions and training on how to processing cascara into cascara herbal tea. The community members of the Women's Farmers Group (KWT) Elong Tuna feel that from this Community Service Program (PkM) they have gained knowledge in processing cascara and are motivated to produce cascara herbal tea in order to increase income for the KWT members.

Abstract

Pengendalian pertumbuhan mikroorganisme patogen merupakan salah satu prioritas utama dalam bidang pangan, kesehatan, dan lingkungan. Salah satu strategi yang semakin dikembangkan adalah pemanfaatan senyawa antimikroba alami yang berasal dari tanaman. Ekstrak daun dan buah belimbing wuluh (Averrhoa bilimbi L.) diketahui mengandung senyawa bioaktif yang berpotensi menghambat proliferasi mikroorganisme. Penelitian ini bertujuan untuk mengkaji efektivitas antimikroba dari ekstrak daun dan buah belimbing wuluh terhadap tiga jenis bakteri patogen, yaitu Staphylococcus aureus, Bacillus sp., dan Salmonella sp.. Metode yang digunakan adalah difusi agar dengan cakram kertas, di mana zona hambat yang terbentuk menjadi indikator aktivitas antibakteri. Hasil pengujian menunjukkan bahwa ekstrak daun memberikan daya hambat lebih besar dibandingkan ekstrak buah, terutama terhadap S. aureus (6,6 mm vs 3,5 mm) dan Salmonella sp. (7,3 mm vs 5 mm). Kedua jenis ekstrak menunjukkan daya hambat sedang terhadap Bacillus sp. (7,9 mm dan 6,2 mm). Perbedaan efektivitas ini kemungkinan besar dipengaruhi oleh perbedaan kandungan senyawa bioaktif seperti flavonoid, tanin, dan saponin yang lebih melimpah pada bagian daun. Meskipun aktivitas antibakterinya belum melampaui antibiotik sebagai kontrol positif, temuan ini memperkuat potensi ekstrak daun belimbing wuluh sebagai agen antimikroba alami yang dapat dikembangkan lebih lanjut sebagai alternatif senyawa sintetis.

Abstract

Shrimp anchovy paste is a traditional fermented condiment widely consumed in Asia. Regional variation in raw material selection and processing practice may affect physicochemical composition and microbial ecology, with implications for quality and safety. This study characterized the physicochemical and microbiological properties of shrimp anchovy paste produced in Sumbawa, East Lombok, and Central Lombok. Samples were analysed for proximate composition, texture, colour, amino acid profile, total plate count, lactic acid bacteria enumeration, and cell morphology. Statistical differences were evaluated by one way analysis of variance and Duncan multiple range test using SPSS version 26. Moisture content increased from Sumbawa (37.83%) to East Lombok (43.25%) and Central Lombok (46.17%). Ash content was highest in Sumbawa (28.09%) and lowest in Central Lombok (18.27%). Protein was substantially lower in East Lombok (12.96%) compared with Sumbawa (23.23%) and Central Lombok (23.05%). Fat and instrumental hardness did not differ significantly among regions. Amino acid analysis identified glutamic acid as the dominant free amino acid, most abundant in Central Lombok (25685 ppm) and Sumbawa (23560 ppm). Microbiological profiling indicated the highest total plate count in Sumbawa (2.79 log CFU/mL) and the highest lactic acid bacteria count in East Lombok (2.57 log CFU/mL). Cell morphology revealed Gram negative bacilli in Sumbawa and Gram positive bacilli in East and Central Lombok. Regional differences in raw material ratio, salt application, drying regime, and microbial succession drive variation in composition and microbiology of shrimp anchovy paste.
