Abstract

Increasing the human activity may lead to decrease utilization of river waters quality. The purpose of this study were to find out structure of macrozoobenthos community as bioindicator of waters quality in three estuaries of Ampenan district; find out the chemical and physical conditions of waters; determine the relationship of physical chemical of waters and macrozoobenthos diversity indices. The study was conducted by dividing of each estuary into 10 stations. Community structure and physical chemical waters parameters was analyzed descriptively. The relationship of physical and chemical waters quality parameters with macrozoobenthos diversity indices was analyzed by regression. The results showed that 8 species found in the estuary of Berenyok, 11 species in the estuary of Ancar and 12 species in the estuary of Jangkok. Conditions of community structure in three estuaries balanced enough up to unstable. Physical and chemistry waters quality in three estuaries are still below the quality standard except for Hg. In Berenyok and J angkok estuaries Hg values obtained in excess of standard quality. Pollution levels in the three estuaries ranging from moderate to heavily polluted. There is a linear correlation between macrozoobenthos diversity indices and DO parameter in each estuary.

Abstract

The research was done in the area of subak Tibuhbiyu, Kerambitan District, Tabanan Regency to get the rational suitable fertilizer formulation as a environmentally friendly on rice plant. To achieve these objectives, the research conducted through several activities, namely: soil survey, physical and chemistry of soil analysis, the factorial field experiment of rice plant response for fertilizer treatments, and analysis of the soil quality after harvest. Most of Subak Tibuhbiyu paddy soil was a medium soil fertility status (60%), due to the high value of the cation exchange capacity (CEC) and base saturation (KB). Provision of compost can also reduce the use of NPK fertilizers. The best formulation fertilizer are 10 tons ha-1 compost in combination with 75% of the NPK recommendation, which can provide a high grain yield, ie 7.35 tones ha-1. In general, added of NPK fertilizer, organic fertilizer, or the each other combination, not cause pollution to the soil environment, because its had a medium quality of soil after harvest.

Abstract

Floods are natural disasters that took place almost all over the world including Indonesia. Indonesia is very vulnerable to disasters because has characteristic a huge amount of rainfall throughout the year. Flood disaster is one of the disasters that often occur in Indonesia. GSMaP is one kind product of satellite precipitation has one hour temporal resolution, 0.1x0.1 degree horizontal resolution, world-wide coverage and operated by JAXA. In this study were investigate the characteristic of rainfall pattern before floods occur by processing hourly GSMaP MVK at each location large flood events occur in Indonesia on 2006-2010. The large flood events data collected from Dartmouth Flood Observatory (2006-2010) and Ministry of Public Works of the Republic of Indonesia (2006-2010). Based on the processing result, generally Indonesia has two characteristic of rainfall patterns before floods occur namely: short term rainfall period and long term rainfall period. Based on the compilation and classification of 69 locations large flood events in Indonesia, from three rainfall pattern before flood occur it obtained 42 locations or 60.87% in the category short term rainfall period, 27 locations or 39.13% in the category long term rainfall period.

Abstract

Indian Ocean, particularly on Southern part of ,Java and Bali was identified for some big pelagic fish. Among all of the big pelagic fishes, big eye tuna is the highest commercial value compare with other species There are several research which studied the relationship between the existence of tuna and environmental factor. Sea Smface Temperature (SST) was used as a main oceanographic factor to relate with big eye tuna abundance. SST data \\aS derived from Level 3 AQUA M0DIS data. In my paper, 1 use additional simple statistical method to prove that SST and big eye tuna has a good con-elation. I used polynomial regression and geographic information system method to improve correlation value of lhe data. There arc three critical value and four equation. Based on the data analysis, SST has significant value to big eye tuna abundance in Indian Ocean and has high correlation.
