Pengaruh Komposisi Daun Gamal (Gliricidia sepium Hbr.) dan Kotoran Sapi dengan Nutrisi Pisang terhadap Rasio C/N Kompos

It has been done a research on the effect of the composition of gliricidia sepium Hbr. And cow dung with banana nutrition on the composting process on the C/N ratio. This research was conducted with the aim of knowing the effect of the composition and the length of time required for fermentation. Composting was made with a variety of cow dung : gliricidia sepium Hbr. In a ratio of 1:9, 1:1, 3:2, 7:3, 9:1, and 2:3 in % by using 25% banana nutrition and 100% water from the total weight of the manure. On this research was found that the optimal time is on 14th day with characteristic  of compost  that was produced, equal with the the Indonesia National Standar (SNI Kompos 19-7030-2004). The conclusion is the compcsition of cow dung and Gliricidia sepium leaves did not significant affect to the C/N compost ratio

UJI TOKSISITAS EKSTRAK AIR DAUN KELOR (Moringan oleifera, L) ASAL LAHAN KERING NUSA TENGGARA TIMUR

Moringa Oleifera (Moringa oleifera Lamk) found excessive growth in dry East Nusa Tenggara (NTT) province. The plant has not only been primarily consumed as food especially for its leaves but also is rich in nutrients in its fruits to roots, benefits as coagulants, vitamins, and medicines.  This research studied the toxic effect of the water extract of Moringa leaves to Artemia Salina Leach shrimp larvae according to BST method using water (room temperature) as a solvent, a preliminary study of the antibacterial and the anticancer target of study of the Morinaga. Moringa leaves were macerated for 3 x 24 hours using water, the results of phytochemical tests identified secondary metabolic content, among others, alkaloids, flavonoids, triterpenes, and tannins. The results of the BSLT test showed that the water extract (room temperature) of Moringa leaves had a toxicity level against Artemia Salina Leach as indicated by an LC50 value of 888, 34 less than 1000 ppm. It can be concluded that Moringa leaves have potential as a plant which can later be used as anti-bacterial and anti-cancer
