Abstract

Masyarakat Desa Embung Raja sebagian besar bekerja dalam bidang pertanian dan peternakan. Sebagian besar para petani dalam mendukung produktivitas hasil panen, masih menggunakan pupuk kimia. Kotoran ternak dan sampah organik juga masih menjadi masalah, yang sebenarnya dapat dimanfaatkan menjadi pupuk kompos. Oleh karena itu, dibutuhkan pelatihan untuk mengolah kotoran ternak menjadi pupuk kompos. Tujuan dari kegaiatan pelatihan ini untuk memberikan pengetahuan kepada dan kelompok tani serta warga di desa Embung Raja mengenai cara pembuatan pupuk kompos dari kotoran sapi. Kegiatan ini dimulai dari tahap perencanaan, survey lokasi, pengantaran surat permohonan pemater, serta tahap pelaksanaan kegiatan. Hasil dari pengabdian masyarakat ini adalah berupa sosialisasi dan praktik langsung pembuatan pupuk kompos, dan pupuk kompos yang siap digunakan oleh masyarakat dalam menanam tanaman. Diharapkan pelatihan ini dapat memecahkan permasalahan pupuk dan juga mengurangi limbah kotoran hewan ternak.

Abstract

Renggak leaves (Amomum dealbatum Roxb.) contain secondary metabolites such as flavonoids, terpenoids, and tannins, which act as antioxidants. Previous research has shown that ethanol extract of renggak leaves has moderate antioxidant activity using the DPPH method. However, research on the antioxidant activity of the extract is limited, thus further investigation at the fraction level is needed. This study aims to identify the secondary metabolite content and antioxidant activity using the ABTS method (2,2-azinobis-3-ethylbenzothiazoline-6-sulfonic acid) of the ethanol extract and ethyl acetate fraction of renggak leaves. The renggak leaf samples were extracted using maceration with 96% ethanol (1:10), followed by fractionation with water, n-hexane, and ethyl acetate using a separatory funnel (1:1). Secondary metabolite screening was conducted on the ethanol extract and ethyl acetate fraction. Antioxidant activity was measured based on the reduction in absorbance at the ABTS maximum wavelength, expressed as IC50 (inhibitory concentration 50%) values, with ascorbic acid as a comparison. The secondary metabolite screening results indicated that both the ethanol extract and ethyl acetate fraction of renggak leaves contain alkaloids, flavonoids, tannins, and steroids. The antioxidant activity of the ethanol extract was very weak with an IC50 value of 236.11 ppm, whereas the antioxidant activity of the ethyl acetate fraction was strong with an IC50 value of 86,95 ppm, compared to the antioxidant activity of ascorbic acid with an IC50 value of 10,00 ppm.

Abstract

Free radicals are unpaired electrons, making them highly reactive and unstable, with the potential to damage body cells and trigger various diseases. To prevent the adverse effects caused by free radicals, the body requires protection from antioxidant compounds. Numerous studies have confirmed that certain types of plants possess antioxidant activity, tested using the ABTS method. This review article aims to identify plant extracts with antioxidant activity based on the ABTS method. The method used was a literature study, focusing on journal searches on the Google Scholar platform using relevant keywords and concentrating on publications from the past ten years. The review results indicate that extracts from different plant parts show varying levels of antioxidant activity, ranging from very strong to moderate, supported by different IC50 values.
