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

Paddy field ecosystem is a complex ecosystem and build a food web. Tri-trophic interaction in paddy field involves rice plants as producers, phytophagous and neutral insects as first consumers, and their natural enemies as second consumers..This study was conducted to analyze the effect of siam weed and neem cake compost on abundance arthropod in black rice. The experiment was carried out in paddy field at Jatinangor from May to November 2018. The experimental method was used a randomized Complete Block Design with five treatment as follow neem cake, siam weed compost, cow manure, synthetic fertilizer and control) and six replications. The results showed, that arthropods abundance and plant performance including plant height, tiller number and SPAD value were higher in siam weed compost and neem cake treatment if compared with other treatments. Furthermore, there were strong correlation between insect herbivore with natural enemies in siam weed treatment.
