Chromolaena odorata (L.) is a organic material as potential compost and botanical pesticides since it compounds have the potential as a pesticides is secondary metabolite. The aim of this research was to know the effects of siam weed Chromolaena odorata compost on production of secondary metabolites in the chili. The experiment was arranged in complete randomized design consisted of four treatments (no fertilizer, cow manure, siam weed compost and inorganic fertilizers) and four replications. The research was done by comparing the chemical content of leaves analyzed by Gas Chromatography-Mass Spectrometry (GC-MS) and phytochemical test. This study was conducted from September 2010 to Februari 2011, in the green house of Departement Plant Pest & Diseases, Faculty of Agriculture. In order to the extraction and characterization of secondary metabolites was conducted at the Laboratory of Chemistry, Universitas Gadjah Mada. Overall, the results of study showed that C. odorata compost could give positive effect on production of secondary metabolites as follow terpenoid, alkaloid, steroid and flavonoid on chili

ABSTRACT A black rice cultivation study was conducted at Kampung Cinenggang, Cileles Villages, Jatinangor. This research analyzed the effect of organic fertilizer such as siam weed compost and neem cake waste to black rice growth and soil chemicals. The experiment was arranged in randomized block design consisted of five treatments and six replications as follow : neem cake waste , siam weed compost, cow manure, urea were used as the N sources by comparing with no application (control). Overall the result of the study showed that there were no significant differences among treatment in plant growth characters such as plant height and SPAD, except control. In tiller number, the effect of neem cake waste and siam weed compost were significant different if compared with other treatments. Furthermore, the effect of neem cake waste gives a positive effects to soil chemicals which in turn enhanced the growth of black rice. it is recommended that organic fertilizers (neem cake waste and siam weed compost) be utilized instead of chemical fertilizer. Keywords: black rice , neem cake waste, organic fertilizer, siam weed compost, plant growth, soil chemicals

The aquatic ecosystems in rice fields has macroorganisms such as aquatic arthropods which have an important function in the food web. The siam weed and neem cake can be utilized as organic fertilizer to support the productivity and biodiversity of the paddy field, This research aims to understand application of organic fertilizer on diversity of aquatic arthropods and black rice performance in the field ecosystem. The experiment was carried out in paddy field at Jatinangor from January to June 2020. The method used was an experimental method with a Randomized Complete Block Design consisted of five treatments (neem cake, siam weed compost, cow manure, synthetic fertilizer and control) with six replications. The result showed that the abundances of aquatic arthropods have tendency to be higher in neem cake at 1104 individuals and siam weed compost treatments at 905 individuals compared to the cow manure, NPK and control. Furthermore, the diversity index of the aquatic arthropods in all treatments were categorized as moderate with details as follow neem cake (H’=1,726), cow manure (H’=1,450); synthetic fertilizer (H’=1,458); siam weed compost (H’=1,450) and control (H’=1,502). In addition, the evenness index (E) of aquatic arthropods was higher in neem cake treatment (E=0,623) compared to other treatments. Whereas, the dominance index (C) and richness index (R) in all treatments showed no dominant species and it classified as low category. The results also showed that the siam weed compost were not significantly different with all treaments except NPK (synthetic fertilizer) in plant hight, tiller number and SPAD value.
