The goal of this research is to study the dynamics changing of temperature, weight and volume of wastes during composting process in Cakung Slaughterhouse. The composting process was done using windrow system for 65 days. Windrow was turned mechanically using compost turning machine once a week. Composition of input wastes was calculated based on its volume and specific weight. Regularly, windrows were measured of their volume, weight and temperature. The composting shows that weight and volume reduction was exponentially done in the two of the first weeks. The temperature also exponentially increased in that time. Those indicated that the increasing of metabolisms and development of microbiology during composting process. Weight and volume reduction reached about 80 percent, and their temperature reached above 55oC during first weeks. The dynamics changing of the temperature and volume/weight reduction was the key parameter for evaluating composting process.

Indonesia’s rich supplies of corals and reef fish are endangered by destructive fishing practices. Cyanide and blast fishing are widespread throughout the archipelago even in protected areas. Indonesian reefs are also subject to various pressures from inland activities. Forestation and other land-use changes have increasedsediment discharge onto reefs, and pollution from industrial effluents, sewage, and fertilizer compounds the problem. Cumulatively, these pressures appear to have significantly degraded Indonesia’s reefs over time. Unfortunately, Indonesia has only limited monitoring. Few reefs are regularly studied, making the assessment of condition and change for the country quite difficult. Currently, most monitoringmindicates clearly that reef condition is declining. This article showed the status, biology, and monitoring-rehabilitation method of coral reef in Indonesia.

Aims of study were to compare flower structure, pollen viability and pollen tube growth rate of two Diospyros species neighborly live in Cibinong Science Centre (CSC) park, Diospyros blancoi and D. celebica, and pursue if pollen-tube growth rate shire reasons endemic distribution of D.celebica in native habitat. Floral structurewas in situ or ex situ morphologically observed. Germination test and pollen tube growth incubation were done in Sarfatti medium and digitally captured and computerize analysis. The result showed that, both species have flower part resemblance each other. D. blancoi has bigger size in almost all flower parts. D. blancoi showed much more pollen viability (41% vs 7%) and tube growth rate than D. celebica1 (66 vs 0.57 μm per minute). Average pollen-tube length of both species at about 31/2 hours incubation was significantly different each other (342.679 ± 37.067 vs 128,673 ± 49,215μm). Most observed D. blancoi female trees set high number of fruit year to year and almost observed D. celebica female trees set very low number of fruit and some time without fruit in the year. It is associated with geographical distribution difference between the two species. Very significantlydifferent in pollen-germination percentage and pollen-tube growth rate provide a tool of further study to know microenvironment for reproduction and propagation of the endemic species, D. celebica.
