Abstract

Petani pembesaran lele banyak yang mengeluh gagal dalam usahapembesaran lele. Kegagalan tersebut disebabkan oleh penggunaan pakandan kolam yang tidak efisien serta harga pakan mahal. Tujuan kegiatanpengabdian masyarakat ini memberikan wawasan tentang metode barudalam usaha pembesaran lele yang menguntungkan. Mitra pengabdiankegiatan ini yaitu kelompok pembesaran lele Sungut Emas di Boyolali danpetani-petani pembesaran lele disekitarnya. Metode pengabdiandilakukan dengan metode substitusi ipteks secara teori, praktek lapangan,dan pendampingan. Substitusi ipteks secara teori meliputi penjelasantentang pembesaran lele tebar padat dan aplikasi enzim dalam efisiensipakan. Materi praktek lapangan meliputi cara persiapan air, carapengelolaan air, cara menangani penyakit dan cara memberi pakan.Simpulan, substitusi ipteks pembesaran lele tebar padat mampumenyelesaikan masalah yang dihadapi petani pembesaran lele tebar padatsehingga keuntungan usaha meningkat.

Abstract

Terminalia bellerica is well-known for producing edible fruits with pharmacotherapeutic properties. Traditional healers use these species to treat and control diabetes mellitus, its side effects, and other illnesses. Involved in this disease's pathophysiological process, extensive research has been conducted to validate and comprehend these bioactive claims scientifically. This research aims to ascertain the bioactive metabolite contents of different solvent polarities, including ethyl acetate, hexane, distilled water, and methanol. The phenol concentration was determined using the Follin-Ciocalteu procedure to be between 23.45 and 160.41 mg GAE/g. The aluminum chloride colorimetric technique measured flavonoid concentration from 88.52 to 7.12 mg QE/g. The quantitative values of tannic acid, which spanned from 0.78 to 5.32 mg TAE/g, were determined by spectrophotometry UV-VIS. The extracts' capacity to reduce free radical damage ABTS (2, 2' azinobis (3-ethylbenzene-thiazoline-6-sulfonic-acid) and DPPH (2,2-diphenyl-1-picrylhydrazyl) was examined. The extract ethyl acetate exhibited the most significant level of antioxidant activity, with IC50 values for DPPH and ABTS of 28.17 and 22.22 g/ml, respectively. Staphylococcus aureus (23 mm) and were tested for antibacterial and antifungal activity in a methanol extract (21 mm). In vitro, antidiabetic activities were assessed using α-glucoside and α-amylase inhibition. The ethyl acetate extract has α-glucoside inhibition IC50 of 23.04 g/ml and α-amylase inhibition IC50 of 25.35 g/ml. T. bellerica seed includes secondary metabolites that show promise as lead chemicals in creating potent medications.
