Abstract

Penelitian ini bertujuan untuk mengkaji pengaruh konsentrasi etanol dalam proses ekstraksi daun pulutan terhadap aktivitas antibakteri, khususnya terhadap Propionibacterium acne, Staphylococcus aureus dan Staphylococcus epidermidis. Ekstraksi dilakukan dengan etanol pada konsentrasi 30%, 60%, dan 90%. Hasil penelitian memperlihatkan konsentrasi etanol berbanding lurus dengan diameter daya hambat, meskipun rendemen yang diperoleh menurun. Rendemen tertinggi diperoleh dengan etanol 30% (36,36%), diikuti oleh etanol 60% (19,27%), dan terendah dengan etanol 90% (8,48%). Uji antibakteri menunjukkan kemampuan tertinggi terhadap S. aureus dan S. epidermidis dicapai dengan ekstrak etanol 90% pada konsentrasi 500 mg/mL. Penelitian ini menegaskan bahwa konsentrasi pelarut berperan penting dalam mengekstraksi senyawa bioaktif yang efektif dalam menekan perkembangan bakteri.

Abstract

Ketidak mampuan dalam memanfaatkan sumber daya yang ada secara optimal yang menyebabkan lambatnya pergerakan ekonomi masyarakat dan terjadinya ketimpangan ekonomi dan sosial. Upaya strategis menghilangkan ketimpangan tersebut dengan membukakan akses bagi masyarakat desa melalui peningkatan pengetahuan dan keterampilan melalui program pemberdayaan dalam bentuk pelatihan. Kegiatan pengabdian ini dilakukan untuk memberikan solusi terhadap permasalahan yang terjadi di Desa Bonde sehingga lebih optimal memanfaatkan potensi desa yang dimiliki melalui pelatihan pengolahan berbasis pangan lokal. Hasil yang didapatkan dari kegiatan ini adalah meningkatnya pengetahuan dan pemahaman peserta tentang pengolahan pisang sebagai pangan lokal, meningkatnya kemampuan dan keterampilan peserta mengolah pisang menjadi bolu pisang, dan meningkatnya minat dan keinginan untuk mengolah secara mandiri dan menjual produk bolu pisang.

Abstract

Temulawak, also known as Curcuma xanthorrhiza Roxb., is a long-used medicinal plant that is frequently utilized as an ingredient in traditional medicine. At harvest, the ginger rhizome has 80–90% water content. When ginger is harvested with a high water content, its quality declines and its selling price drops. The purpose of this study is to ascertain how variations in the concentrations of sugar and water affect the color and chemical characteristics of temulawak powder.  Water content, flavonoid and tannin levels, and antioxidant activity were all tested as part of the analysis. The data was statistically calculated using the Complete Randomized Block Design, and analysis of variance (ANOVA) was carried out at a 95% confidence level. whether the actual differences in each therapy were shown by the Duncan Multiple Range Test (DMRT). The findings demonstrated that the water content, flavonoid levels, tannin levels, and antioxidant activity are all significantly impacted by the amount of water and the addition of sugar. When 100 ml of water and 100 g of sugar are mixed together, the temulawak powder's water content is 3.01%, its flavonoid content is 1.73 mg GAE/g bk, its tannin content is 10.99 mg/100g, and its antioxidant activity is 83.30% RSA.

Abstract

: This study aimed to evaluate the chemical characteristics of snack bars formulated from grain germinated rice flour combined with penja fish (Sicyopterus spp.) flour as a potential local protein rich ingredient. The experiment employed a Completely Randomized Design (CRD) with two formulations: P0 (100% germinated rice flour : 0% penja flour) and P1 (80% germinated rice flour : 20% penja flour). Chemical analyses included moisture content, ash, protein, carbohydrate, and total energy. The results showed that the addition of 20% penja flour significantly affected (p<0.05) all chemical parameters. Treatment P1 exhibited the highest values of ash (1.82%), protein (34.65%), carbohydrate (11.06%), and total energy (437.5 kcal/100 g), while reducing moisture content to 14.51%. The increase in nutritional value was attributed to the high protein content of penja fish and the nutrient contribution from germinated rice flour. These findings indicate that combining germinated rice flour and penja fish flour has strong potential for producing nutrient dense local snack bars.
