Abstract

The Regional Ocean Modeling System (ROMS) was used to simulate the Indonesian Archipelago Sea current and temperature with two different vertical mixing schemes. One corresponds to the newly developed K-Profile Parameterization (KPP) scheme and the other is adapted from the stability frequency of Brunt-Vaisala Frequency mixing (BVF). It is found that, both of schemes produce reasonably realistic sea surface temperature (SST); however, the root mean square error (RMSE) values from the BVF vertical mixing were less than the KPP vertical mixing. The RMSE values from the BVF vertical mixing at northwest and southeast monsoons can be reduced down to 5.1607E-01 0C and 5.7639E-01 0C respectively. These validation results reveal that accuracy of the BVF vertical mixing is better than the KPP vertical mixing.The model results based on the BVF vertical mixing scheme show that the direction of Java Sea, Karimata and Sunda Straits surface current are strongly affected by the zonal wind system. The direction of surface current was change following the monsoonal wind system. On the other hand, the Makasar Strait surface current tend to flow southward throughout the year with annual variations in transport are related dynamically to the monsoon winds. These southward surface currents are known as Indonesian Through Flow (ITF) and it is governed by strong pressure gradient from the Pacific to the Indian Oceans. The signals of El Nino 2002 event also can be detected by the model results. It recognized that the strong Equatorial Counter Current flows to eastward to the central part of the Pacific Ocean. The Makasar Strait surface current was stronger than usual but the Karimata Strait surface current was weaker during this period.

Abstract

Timuhun irigation channel is one of the irigation water sources which is located in the District of BanjarangkanKlungkung Regency of Bali Province which is flowing from its origin at Bubuh River which flows passses three villagesof Bangbang, Nyanglan, and Timuhun villages.The objective of this study was to determine the properties of pollutant of kacang koro as well as to determine theperception of the owner/industry workers and the community at the Timuhun village produced during the washingprocess.This study was conducted from December 2007 to Januari 2008. The sample of the irigation water of Timuhunwas taken from nine locations and the sample of the waste water was taken from three locations. The index of thepollution was calculated and compared to the Governor Regulation Number 8 of 2007 while the community perception onthe waste impact of the kacang koro washing was analyzed using percentage formulae.The finding of the study shows that the pollutant properties of of the waste water have exceeded the maximumlevel of quality standard covering parameters of TSS, COD, BOD5 and ammonia. The pollution of the Timuhun irigationby the waste water from the kacang koro washing is indicated by the high property of the water quality parameter onBOD5 and COD. Based on the pollution index (PI), it was found that the water quality of Timuhun irigation reached amild pollution in all criteria of water quality of class I, class II, class III, class IV except the origin location which is stillin good condition. The perception analysis on the waste water impact showed that the community of Timuhun have a badperception, so the owner and industry workers have a good perception.
