Abstract

Sedimentation and turbidity are contributed significantly to decrerasing population of biotic organisms in aquatic ecosystem. Impact to faunal population in lotic environment may be expressed by pervasive change in local food chains starting from primary trophic levels. Decreasing in primary production associated with increasing a number of sediment content dan high in turbidity value and impact on negative level of production of food availability related to a number of zooplankton, insects, freshwater molusca, and then fish. Direct effect of each trophic levels is affected to mortality levels, decreasing physiologicsl function, and rejection, however decreasing food availability at the trophic level that resulted in depressing growthrate, reproduction and recruitment function. The effect of turbidity on aquaticorganisms often as inconsistent in watershed and water treatment. But in this case the different is significantly because of lack of correlation between sediment concentration (mg/liter) and measurement unit (NTU). The use of NTU as a unit measurement in change with suspended sediment (TSS) to predict the effect of aquatic biota in watershed is ambigious. At the same time, NTU measurement in different watershed is depending on the concentration of suspended sediment. To monitore the effect of turbidity in local watershed we are recommended to use the baseline data to investigate the effect of local watershed that arecorrelated betweensuspended sediment and NTU This study could be happenned through a series of monitoring of water flow based on seasonal dynamic and then by using this baseline data, we are creating a useful solution to decrease sediment input into the river water.

Abstract

Water resources should be managed integratively in the term of forestry, agriculture, social economy, conservation and civilian. Bone-Bolango Regency, in the center, eastern and western part, passed by Bone dan Bolango Rivers. The upstream area of Bone and Bolango Rivers is Nani Wartabone national conservation forest. The watershed of Bone and Bolango Rivers are located among Bone Bolango, Gorontalo, Limboto, and Gorontalo Major region in the Gorontalo Province, meanwhile in thelarger system, they have share watershed to the North Sulawesi Province.Until now the watershed of Bone-Boelango is managed by Balai Pengelolaan DAS Boen Bolango, whereas groundwater resources develepment managed by P2AT, and local stakeholders such as Dinas Kimpraswil Tingkat I Propinsi Gorontalo and Dinas Kimpraswil Pemda Tingkat II Kabupaten Bone Bolango. The analysis of the annual debit of Bone and Bolango Rivers show that the trend of the average debit ratio to theminimum debit of the same year show gradually higher than dan before because of the deforestration of Bone and Bolango Rivers in the upstream of the rivers. So we have to manage the DAS of Bone and Bolango Rivers by the ecosistem approach to improve the deterioration of the the rivers.

Abstract

Saguling reservoir is one of reservoir located in West Java Province. This reservoir primarily was planned for single purpose to generate the electricity. Water quality in this reservoir is depends on the water quality of Citarum River which have face significant change because of the increased of land use along Citarum River basin. Parameter that tends to increased as well as measured at Saguling reservoir in this study is pH, turbidity and Chlorophyll-α. These results are higher than the permissible limit (PP 82/2001). Its mean that Saguling reservoir water quality is worst, and based on chlorophyll-α contained > 10 μg/L is called as eutrophic waters

Abstract

In year 2002, 2007 and 2008 Jakarta experienced heaviest flood in early February from rain that precipitate in several days ahead. Those rainfalls take place in early morning for few consecutive days. The extreme early morning rainfall occurs due to three dominant phenomena the Madden Julian oscillation wet phase, the cold surge and a vortex in the southwest of Java. The cold surge from north compressed the air mass over the north of Jakarta Bay, picked up as much as water vapor over it and brings to the bay. Especially at night during intense land breeze, south ward movement of compressed and moist air collided frontally with the land breeze andcaused strong uplifting at the coast. The latter phenomenon created strong convection at the Jakarta metropolitan areas at early morning and caused extreme rainfall events. Those daily rainfall rate are almost and exceed the monthly rainfall values. Analises of data from satellite observation, rain gauge, wind and radar imagery prove the mechanism of extreme weather in early morning that cause heavy flood over Jakarta. The incoming of those three phenomena could be predicted in advance with quite a certainty. The MJO is a feature that has 50 days oscillation so that MJO wet phase could be predicted in advance up to 2 weeks. The cold surge that comes from Siberia has index of sudden drop of pressure in Hongkong before propagate to Southeast Asia, thus could be predicted in advance about one week ahead. Lastly the vortex development in southwest of Java could be predicted up to 1 days in advanced. Those information on the three major or dominant weather feature will be a good early warning for heavy flood of Jakarta especially in early February.

Abstract

The operational of Trisakti port , Banjarmasin, South Kalimantan is only 3 hoursperday due to sedimentation and sea lane damaged. This condition became worse inline with forest conversion in hinterland area. Selection of alternative port was carried out at seven coastal areas in Tanah Laut regency. Based on the result of multicriteria analysis, the best location for alternative port is Batakan-Tanjung Coast.

Abstract

Untuk mengetahui karakteristik suatu badan air sungai dengan lebar penampang yang cukup besar memerlukan pendekatan beberapa pengamatan dengan melakukan pengukuran secara vertikal maupun horizontal. Pengukuran vertikal adalah pengukuran secara memanjang dari sisi tepi yang satu kesisi tepi lawannya sedangkan pengukuran horizontal adalah dengan membagi kedalaman sungai. Sehubungan dengan akan dipasangnya suatu sistim pemantauan telemetri disungai Siak dimana sensor akan diletakkan pada tepi sungai dgn jarak kira-kira 20m daritepi sungai, maka untuk mendapatkan data yang mewakili telah dilakukanpengukuran secara vertical dengan interval 20 m dan pengukuran horizontal 0,5 m, 5 m, 10 m, 15 m dengan beberapa parameter yg diukur adalah temteratur, pH, kandungan Oksigen, konduktivitas, turbiditas, kecepatan aliran. Berdasarkan hasil pengukuran dan pengamatan dari beberapa parameter kuantitas dan kualitas air pada penampang badan air sungai, hanya kecepatan aliran sungai dan kandungan oksigen terlarut yang memiliki perbedaan yang signifikan. Kecepatan aliran sungai pada bagian tengah sungai dapat mencapai 10 x kecepatan aliran pada tepi sungai,terutama pada saat kondisi surut, sedangkan pada saat pasang hanya terjadi pengaliran dibagian tengah dan dibagian tepi sungai tidak terjadi pengaliran (kecepatan aliran 0). Sedangkan kandungan oksigen terlarut pada bagian tengah sungai menunjukkan nilai yang lebih besar sampai dengan 0,5 - 0,6 mg/l dibandingkan pada sisi tepi sungai. Dengan demikian penempatan alat ukur kualitas air maupun kuantitas air (terutama parameter kecepatan aliran) secara permanen yang biasanya hanya mungkin dilakukan pada bagian tepi sungai, perlu memasukkan faktor koreksi sebagai hasil final yang dapat mewakili konsidi suatu profil badan air sungai.
