Abstract

This service aims to help the Nyiur Melambai Farmers Group in Tomohon City in increasing the productivity of laying ducks through the application of locally made feed. The main problems faced by partners are the high price of commercial feed, low knowledge in making alternative feed, and suboptimal business management. The solutions implemented include training in processing feed from local ingredients, introduction to appropriate technology, and cage renovation. The results of this activity show an increase in feed production, a reduction in feed costs, and an increase in the capacity of partners in business management. This service contributes to increasing partner income and strengthening the sustainability of the laying duck business.

Abstract

Indonesia dikenal sebagai negara yang tinggi dengan keanekaragaman hayati flora dan fauna. Penggelompokkan tumbuhan dalam flora didasarkan pada keadaan atau sifat khusus, lingkungan, wilayah, iklim, sebagaimana flora gulma, flora tanaman dan flora asli. Gulma yakni organisme pengacau tanaman, dapat menghambat perkembangan, pertumbuhan, dan produktivitas tanaman. Tumbuhan Ageratum conyzoides L. (bandotan) yaitu gulma yang diketahui terkandung senyawa saponin, tanin dan flavonoid, yang punya banyak manfaat termasuk diantaranya antibakteri. Penelitian ini tujuannya dalam melihat inhibisi gulma daun bandotan (Ageratum conyzoides L.) terhadap pertumbuhan bakteri Staphylococcus aureus yang dijumpai melalui terdapatnya zona hambat. Penelitian ini ber jenis eksperimental laboratorium mempergunakan RAL (Rancangan Acak Lengkap) melaui lima perlakuan yaitu empat konsentrasi infusa daun bandotan dan kontrol aquadest dengan masing-masing 3 kali pengulangan untuk bakteri Staphylococcus aureus. Pengujian dilakukan pada Laboratorium Fakultas Matematika dan Ilmu Pengetahuan Alam yang dilangsungkan di bulan Juni 2023. Hasil pengujian memperlihatkan inhibisi gulma daun bandotan terhadap pertumbuhan bakteri Staphylococcus aureus dengan konsentrasi 25%, 50%, 75%, dan 100%. Infusa gulma daun bandotan konsentrasi 50% sama dengan konsentrasi 75% dan konsentrasi 100% untuk inhibisi pertumbuhan bakteri Staphylococcus aureus.

Abstract

Antibacterial is a compound used to control the growth of harmful bacteria. Mangrove plants are strongly suspected to have bioactive content, the bioactive content contained in mangrove plants is useful in the pharmaceutical field as a medicinal ingredient. Sonneratia alba root contains secondary metabolite compounds Flavanoids, tannins and alkaloids that act as antibacterials. The purpose of this study was to determine the antibacterial activity of S.alba ethanol extract against Staphylococcus aureus bacteria and Escherichia coli bacteria. Extraction method by maceration, long extraction time 3 days. The extract obtained is then evaporated solvent in the rotary evaporator then the extract results are made concentrations of 25?g, 50?g, 100?g, and 150?g. antibacterial testing using the Kirby-Bauer method. The results showed that at concentrations of 25?g, 50?g, 100?g, and 150?g Sonneratia alba mangrove roots had antibacterial activity. But those that have strong antibacterial activity in Escherichia coli bacteria are at a concentration of 50? with while in Staphylococcus aureus bacteria are at a concentration of 150?g with an inhibitory zone of 18.6mm, and in Escherichia coli bacteria with an inhibitory zone of 18,3mm.

Abstract

Salmonella typhi is the primary bacterial cause of typhoid fever, which remains a serious health concern in developing countries, including Indonesia. This study aims to evaluate the inhibitory activity of sea grape (Caulerpa racemosa) extract against Salmonella typhi. The extract was obtained through maceration and tested using the agar diffusion method with paper discs at various concentrations (100, 200, 300, and 400 µg/disc). The results showed that C. racemosa extract inhibited the growth of S. typhi with average inhibition zone diameters of 25 mm (100 µg), 27.3 mm (200 µg), 28.8 mm (300 µg), and 29.5 mm (400 µg). The negative control (distilled water) showed no antibacterial activity. Based on classification, all concentrations exhibited very strong antibacterial activity. A higher extract concentration corresponded to greater inhibitory effect. These findings suggest that C. racemosa has potential as a natural antibacterial agent against S. typhi and may be further developed for alternative typhoid treatment.

Abstract

This study aims to test the antibacterial activity of Scleria sumatrensis extract against Propionibacterium acnes, a bacteria that causes acne. Extraction was carried out using the maceration method using 96% ethanol, and the antibacterial activity test was carried out using the diffusion method using a concentration of 100–500 ?g/disc. The results showed that the extract provided moderate antibacterial activity at a concentration of 100 ?g/disc and increased to strong at a concentration of 200–500 ?g/disc. S. sumatrensis extract contains secondary metabolite compounds such as phenolics, flavonoids, alkaloids, tannins, steroids, and terpenoids that play a role in inhibiting the growth of P. acnes through various mechanisms, including cell membrane damage, inhibition of protein synthesis, and disruption of bacterial metabolism. Based on the results of the study, S. sumatrensis extract has the potential as a natural antibacterial alternative for acne treatment without significant side effects or the risk of antibiotic resistance.
