Abstract

MAKİNG COMPOST FERTİLİZER FROM COFFEE PEEL WASTE İN THE NAGARİ KOTO TUO COFFEE-PRODUCİNG AREA, WEST SUMATRA. Coffee husk waste in the Nagari Koto Tuo coffee producing area is not used optimally. It just became a pile of garbage in several places. The others were burned which can cause health problems in the future. One alternative to manage coffee husk waste is to fermentate it into compost. The community service for the bioconversion of coffee husk waste into fertilizer is carried out in three steps. The aim of this activity is to increase the knowledge and skills of the community in utilizing coffee skin waste. The practice of making compost was carried out in a composter using the EM-4 bioactivator. The achievement obtained from this community service was that participants were able to understand the bioconversion process of coffee skin waste into compost, which was proven by the percentage of knowledge and skills (greater than 80%).

Abstract

Sambiloto (Andrographis paniculata) is a member of the Acanthaceae family reported to synthesis various bioactive compounds and has biological activities. One of the activities is antioxidant. An alternative source of searching for antioxidant compounds from Sambiloto is its endophytic fungi. The research aims to examine the content of secondary metabolites and determine the antioxidant activity of the BJS-3 endophytic fungus associated with Sambiloto seeds. The steps of the research were inoculation, optimization, fermentation, as well as extraction using ethyl acetate to obtain crude extract (EtOAc). Crude extract of fungal BJS-3 was evaluated for their phytochemical screening and antioxidant activity. The results of the phytochemical test on the endophytic fungus BJS-3 showed positive for terpenoids and phenolic compounds. Furthermore, antioxidant actitvity of extract of fungal BJS-3 was categorized as strong antioxidant properties (IC50 = 67.58 ppm). Keywords:          Antioxidant, Andrographis paniculata, endophytic fungi   Abstrak Sambiloto (Andrographis paniculata) adalah salah satu anggota keluarga Acanthaceae yang mampu mensintesis beragam senyawa bioaktif dan memiliki aktivitas biologis. Salah satu aktivitas tersebut adalah antioksidan. Sumber alternatif pencarian metabolit sekunder dengan aktivitas antioksidan dari sambiloto adalah dengan memanfaatkan jamur endofitik. Penelitian ini bertujuan untuk menguji kandungan metabolit sekunder dan menentukan sifat antioksidan (IC50) dari jamur BJS-3 yang berasosiasi dengan biji sambiloto. Tahapan riset ini meliputi inokulasi, optimasi, fermentasi, dan ekstraksi dengan pelarut etil asetat dan diperoleh ekstrak etil asetat (EtOAc). Ekstrak EtOAc jamur BJS-3 tersebut dianalisis kandungan metabolit sekunder dan sifat antioksidannya. Hasil uji fitokimia pada jamur endofitik BJS-3 menunjukkan positif bahwa ekstrak tersebut mengandung terpenoid dan senyawa fenolik. Sementara itu, uji aktivitas antioksidan mengindikasikan bahwa ekstrak jamur BJS-3 berpotensi sebagai agen antioksidan yang tergolong kuat (IC50 = 67,58 ppm). Kata Kunci:         Antioksidan, Andrographis paniculata, jamur endofitik
