Abstract

ABSTRAKEksplorasi antimikroba berbasis tanaman sangat diperlukan saat ini sebagai upaya pengembangan penyediaan bahan baku alternative obat infeksi bakteri alami. Penelitian ini bertujuan untuk mengetahui jenis ekstrak daun tumbuhan local sarang banua (Clerodendrum fragrans Vent Willd) yang berpotensi sebagai antibakteri terhadap Salmonella enterica. Sampel daun C. Fragrans diperoleh dari desa Raya Usang, Kecamatan Dolok Masagal, Kabupaten Simalungun, Sumatera Utara. Serbuk daun C. Fragrans dimaserasi dengan pelarut bertingkat kepolarannya sehingga diperoleh ekstrak etanol (polar), etil asetat (semi-polar) dan n-heksana (non-polar). Masing-masing jenis ekstrak diuji dengan variasi konsentrasi 10%, 5%, 2,5%, dan 1,25%. Kloramfenikol digunakan sebagai kontrol positif dan DMSO sebagai kontrol negative. Metode uji antibakteri dilakukan dengan metode difusi cakram. Hasil penelitian menunjukkan bahwa aktivitas antibakteri (diameter zona hambat) terbesar terhadap Salmonella enterica secara berurutan adalah ekstrak etanol 5% (polar) sebesar 14,0 mm, ekstrak n-heksan 10% (non-polar) sebesar 11,6 mm, dan ekstrak etilasetat 10% (semi-polar) sebesar 10,5 mm. Ekstrak etanol daun C. fragrans Vent Willd  memiliki potensi antibakteri yang sangat baik terhadap Salmonella enterica. Hasil penelitian ini dapat digunakan sebagai bahan pertimbangan pemilihan jenis ekstrak pelarut dalam penyediaan daun C. fragrans sebagai bahan baku obat antibakteri alami.

Abstract

The high price of chemical fish feed is a serious problem for “Tani Manise" group partners in Sari Rejo village, Medan Polonia sub-district. The reality in the field shows that the presence of golden snail (Pomace sp) in partner locations has not been utilized properly as raw material for organic feed for gurame fish (Osphronemus gouramy). The purpose of this community partnership program (PKM) activity is to assist partners in problems solving faced with the use of the golden snail as organic feed for gurame fish which has economic value and contains good nutrition. To solve the problems faced by partners, an approach is used with planning methods, training and mentoring. The results of PKM activities show that giving organic feed made from golden snail flour can accelerate the growth of gurame fish from the previous 25.0 g / month to 33.3 g / month. There is an increase in growth of about 8.3 grams per month. The high cost of feed can be reduced to 9,000 / kg using organic feed, while the chemical based fish feed is in the range of 13,000 / kg. The implementation of PKM activities can reduce high production costs, accelerate the growth of gurame fish, and the ability of partner human resources in processing raw material for golden snail pests into organic feed containing good nutrition.
