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.

Golden snail (Pomacea canaliculata L.) one of a keypests in rice cultivation in Indonesia. There are three species of golden snails in Indonesia, these are P.canaliculata L., P. insularum D., and P. paludosa S. The purpose of this research was to determine the population density and distribution pattern of golden snails (P. canaliculata) at Jatinangor rice fields. The research was conducted from June 2020 to August 2020 with purposive sampling method on 24 rice fields in 12 villages, specifically Hegarmanah, Cibeusi, Cikeruh, Cipacing, Sayang, Cileles, Cilayung, Cisempur, Cintamulya, Jatimukti, Mekargalih, and Jatiroke in Jatinangor, Sumedang and golden snails identification was conducted at the laboratory. The sample was taken by using purposive sampling method. Each rice fields used as a sampling location has a size 10 m x 5 m with 2 rice fields were determined for sampling in each village. Therefore, total research location was 24 rice fields. Two lands were taken from one village with a distance of ± 1 km between the fields. This is done to get a comparison of environmental conditions. The results showed that the density of snails in the rice fields of Jatinangor was categorized rare with an average density of 3.33 individuals/m². The difference in the density of snails in each area in Jatinangor was caused by differences in the age/phase of rice plants and control techniques. Furthermore, distribution pattern of the golden snail at the rice fields of Jatinangor has a clumped pattern for all locations

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.
