Abstract

Kemiskinan merupakan salah satu masalah mendasar yang dihadapi oleh umat Islam di Indonesia. Fenomena tersebut secara tidak langsung dapat membahayakan kekokohan akidah dan keimanan seseorang. Zakat, infaq dan sadaqah sebagai instrumen dalam pengentasan kemiskinan, tidak hanya menjadi persoalan pribadi, melainkan menjadi persoalan bersama. BAZ dan LAZ yang diatur dalam UU 38 Tahun 1999 tentang Pengelolaan Zakat, harus diakui bahwa upaya untuk melegalkan syari’ah zakat dalam bentuk undang-undang di negeri ini merupakan suatu kemajuan. Maka adalah suatu tanggung jawab  moral dan sosial  bagi setiap muslim  dan pemerintah untuk merealisasikannya. Sebab dengan regulasi, tata kelola, sosialisasi serta  pengelolaan dan pendayagunaan yang amanah, professional dan didukung dengan legalitas hukum yang kuat, pada akhirnya kesejahteraan masyarakat akan terwujudProverty phenomena is familiar with muslim life in Indonesia. This phenomena  is not directly implicated to  decline on the quality of akidah and faith. Zakat, infaq , and shadaqah are the instruments of abolishing proverty, which are not only seen as personal problem, but also communal problem. There fore, it must be seen as state responsibility. Badan Amil Zakat (BAZ) and Lembaga Amil Zakat (LAZ) are Islamic social  institution that regulated with the law of zakat number 38 of 1999, have to be professional, trusteeship, and having a high integrity to increase the society welfare. These are the importance  mission of this regulation is not enough strongly to regulate and to optimalize the management of zakat in Indonesia.

Abstract

Terminalia is the second largest genus of Combretaceae family, consists of 200 species distributed in the tropics and subtropics. Many species of Terminalia are well kown in traditional medicine  in several countries of Africa and Asia. In this study, bark extracts of four species of Terminalia (T. catappa, T. citrina, T. bellirica and T. macadamii) were evaluated for their in-vitro anti-inflammatory and antioxidant activity. Determination of the anti-inflammatory activity was carried out using red blood cell membrane stabilization assay and the antioxidant activity was carried out using DPPH free radical scavenging and ferric reducing power assay. Estimation of total phenolic   content was carried out using Folin-Ciocalteu reagent, while  total flavonoid content using alumminium trichloride reagent. The results showed that extract of T. catappa has the most potent anti-inflammatory activity (IC50= 97,83±0,0100 ?g/mL) and the most powerful  antioxidant activity of DPPH free radical scavenging (IC50= 21,8900 ± 0,0264 ?g/mL) and ferric reducing power (IC50= 87,1533 ± 0,04163 ?g/ mL). The weakest anti-inflammatory activity was T. citrina extract (IC50= 159,35±0,0200 ?g/mL), whereas T. bellirica extract demonstrated the weakest antioxidant activity of  DPPH free radical scavenging (IC50= 44,4867 ± 0,0153 ?g/mL) and ferric reducing  power (IC50= 140,89±0,04 ?g/mL). The extract of T. citrina has the highest content of total phenolic (84,8167 ± 0,53407 mg GAE/g) and flavonoid (23,1200 ± 1,7149 mg RE/g) while the T. macadamii extract has the lowest content of total phenolic (24,3700 ± 0,0173 mg GAE/g) and flavonoid (13,2667 ± 0,3386 mg RE/g).

Abstract

Totally 15 isolates of endophytic fungi were obtained from leaves and young stems of a medicinal plant Albertisia papuana Becc.(Menispermaceae). The antibacterial screening of the ethyl acetate extract derived from the fungi cultures in potato dextrose broth (PDB)were performed on a non eluted Thin Layer Chromatography Bioautography assay (TLC bioautography assay). From the screening test, itwas found that the ethyl acetate extract of the fungus Xylaria sp. DAP-KRI-5 culture showed strong antibacterial activity against Staphylococcus aureus. The isolation of active metabolite based on the bioautography guided assay from ethyl acetate extract of the Xylaria sp. DAP-KRI-5, led us to identify phloroglucinol as a main antibacterial compound. The chemical structure of phloroglucinol was deduced from it spectral data, including UV-Vis, 1H and 13C-NMR, GC-MS and published data elsewhere.
