This study was carried out to investigate treatment of hotel wastewater using a combination of electrocoagulation and adsorption using carbosil prepared from rice husk with pyrolysis method. Electrocoagulation was applied with the aim to remove natural organic matter in the sample, using aluminim as electrodes, with the particular purpose to study the effect of potentials. The treated water was then subjected to adsorption process at different contact times and the performance of the process was evaluated in term of the reduction of the absorbance at maximum wavelength. The performance of the method was defined in term of absorbance reduction at the maximum wavelength of 226 nm, which was determined by scanning the original sample at the wavelength ranging from 200 to 700 nm. According to literature, the maximum wavelength of 226 nm is commonly assigned to benzene structure, most likely from the Alkyl Benzene Sulfonate (ABS) used in detergents. The results obtained indicate that for electrocoagulation process, the highest reduction in the absorbance was achieved using potential of 10 volt. Adsorption process was found to result in the diminish of peak at 226 nm, reflecting that the organic pollutant associated with this wavelength has been completely removed from the water. Characterization of the carbosil using SEM technique revealed that the carbosil has practically homogeneous surface morphology, supporting its ability to adsorb the pollutants from the wastewater. Keywords: adsorption, carbosil, electrocoagulation, hotel wastewater

Bioindicator of the level of destruction of tropical forests and habitats can be seen from the presence of dung beetle. Dung beetle plays an important role in regulating the function of ecosystems. The purpose of this study was to determine the effect of tree shading on the dung beetle diversity in the the Utilization Block of Wan Abdul Rachman Great Forest Park (Tahura WAR). The method used was the trap method. Traps were planted parallel to the soil, then the collected data was analyzed with diversity index (H`), evenness index (E), and abundance index (E). The results found three species of dung beetles, namely Cattarsius mollosus, Onthopagus sp, and Aphodius marginellus. Diversity index of dung beetle in the area with tree shading (H '= 1.09) was greater than without tree shading (H' = 0 ,9). The evennes index (E) and abundance index (R) of dung beetle in the area with tree shading were E = 0.99 and R = 0.66, while without tree shading were E = 0.82 and R = 0.96. Comparison of the diversity of dung beetle in the the area with tree shading and without shading was 21: 8. This means that the dung beetle could maintain a stable population under tree shading. Dung beetle prefers the area with tree shading due to its suitability for the flight activity, suitable habitat condition, and the availability of food sources. The management of Tahura WAR is expected to increase land cover so that the existing ecosystems could remain sustainable. Keywords: biodiversity, dung beetle, Tahura WAR, tree shading

Smallholder's plantations represent 44% of oil palm in Indonesia, and they were known to have agronomic performance much lower than Estate ones. So there is large room for increasing the yield with sustainable cropping system. To better understand the heterogeneity of smallholder's plantations, an agricultural diagnosis has been implemented in a specific place, Riau Province of Sumatra. This study led to well characterize the dynamics of plantation in the region and the diversity of rationalities. Among eight existing types of smallholding plots, there were only three types with yield hardly lower than those of the estate plantations. This reinforced the interest to implement diagnosis through the nutritional status of palms using data from foliar diagnosis and soil analysis. Keywords: dynamic of plantation, palm oil, smallholders, Sumatra

This study was carried out to investigate treatment of brackish water using a combination of electrocoagulation and adsorption using carbosil prepared from rice husk with pyrolysis method. Electrocoagulation was applied with the aim to remove natural organic matter in the sample, using aluminim as electrodes, with the particular purpose to study the effect of potenstials. For this purpose, electrocoagulation experiments were conducted at potential of 4, 6, and 8 volt at fixed contact time of 60 minutes. The performance of the method was defined in term of absorbance reduction at the wavelengths of 254 and 285 nm, since the absorbance at these two wave lenghts was found to correlate well with the amount of organic matter in the water samples. The treated water was then subjected to adsorption process at different contac times of 5. 10, and 15 minutes, and the performance of the process was evaluated in term of electrical conductivity reduction. The results obtained indicate that for electrocoagulation process, the higest reduction of natural organic matter content was achieved using potential of 8 volt, and adsorption porcess of 15 minutes was found to result in reduction of electrical conductivity from 15.13 mS/cm to 10.10 mS/cm. Characterization of the carbosil using SEM/EDX technique revealed that the carbosil has practically homogeneous surface and able to adsorb salt and several other elements from the brackish water. Keywords: adsorption, brackish water, carbosil, electrocoagulation
