Abstract

Discharge regulation and measurement in the irrigation scheme are needed to improve water distribution equity and reliability which are often constrained by damaged sluice gates and discharge measuring devices. Sluice gates which are generally made of iron are often damaged because of corrosion or theft. Whereas the discharge measuring devices are often inaccurate because the required flow condition is often eligible and demolished since in the opinion of the farmers these devices are blocking the water flow. In order to solve this problem, a research was conducted to create sluice gates that can be both, a discharge regulator and measuring device. These gates are made of fiberglass/Glass Fiber Reinforced Plastic (GFRP), which is lighter and more corrosion resistant than steel. The shape of this gate is a rounded sluice gate so that it can be used as a measuring device. Tests were then conducted to determine the hydraulic characteristics of flow and discharge formulas that can be used. These tests resulted a contraction coefficient of 0,867 with error rate (Mean Absolute Percentage Error/MAPE) of 3,8% for free flow and 10,4% for submerged flow or an average of 8,71%. This indicates that this rounded sluice gate is feasible to be used as a measuring device. For operational convenience in the field, operators can be equipped with discharge charts or discharge calculators in Java programs that can be operated on a Java MIDP 2.0 cell phone.

Abstract

In This study is had analyzed thirteen watersheds on the island of Java with wide ranges from 22 km2 to 2666 km2. Watershed characteristics as indicators are the area, the length of main rivers and the shape of the watershed. The Convolution method is used to determine the observation unit hydrograph using rainfall and water level data from automatic stations. This unit hydrograph is compared with four synthetic unit hydrograph methods namely Snyder, SCS, Nakayasu and Gama-1, using the comparison parameters of hydrograph shape and also hydrograph parameters i.e. peak discharge, peak time and time base. The results showed that the method of Snyder, SCS, Nakayasu and Gama-1 have an average deviation of hydrograph shape and peak discharge Qp, consecutive 21% and 36%, 116% and 185%, 17% and 4%, 32% and 24%. Three methods, Snyder, SCS and Nakayasu show direct runoff volume equal to one mm, except the method of Gama-1, so that it has to be corrected to conform with the basic principles of unit hydrograph. Based on the result of this research, it is concluded that the Nakayasu method is more appropriate for watersheds having wide range characteristics.

Abstract

Research to estimate the potential energy generated by ocean currents was done by using two-dimensional hydrodynamic models. The breadth of the waters of Indonesia provides the advantage to tap the potential energy generated by tides, waves and ocean currents. In narrowed straits, bays or other places ocean currents can be very strong and potential for energy utilization. Studies were conducted on the potential of ocean currents in the Sunda, Bali and Sape (East Nusa Tenggara) Straits. Flow velocity potential is used to calculate the percentage of incident flow velocity greater than 1 m/ s. The simulation results indicated that maximum flow velocity occurred at full moon with a condition from ebb to tide and low tide to tide. locations showing a large enough percentage are the Sunda Strait east of Panjurit Island, Bali Strait west of Tanjung Batulicin, and Sape Strait between the islands Matagateh and Sapekah. For each location, the percentage of maximum current events during one year ranged from 40% to 70%.

Abstract

River water quality at various places in Indonesia continues to decline due to pollution by domestic, industrial, and agriculture waste. The Pollutant Index of Solo River is showing conditions from “lightly polluted” to “medium polluted”. These conditions cause the river water quality to be no longer appropriate to its designation. This study aims to assess the level of water pollution of the Solo River using the chemical-physical index. By knowing the level of water pollution, the water resources management can prioritize certain sections for improved water quality, so that it can be developed as a source of raw water for a variety of purposes. The chemical-physical index can be limited to one data measurement (grab sampling data), so its use may be another alternative to rapid determination of water pollution level (WPL). The WPL in the Solo River is “very lightly polluted” to “lightly polluted” during the rainy season, but during the dry season varies greatly. The WPL of the Solo River from upstream to downstream in the period 1995 was identified from “lightly polluted” to “critically polluted” and from, “lightly polluted” to “very heavy polluted” in the period 2002-2011. Decline in water quality had significantly increased as was observed by the rising WPL value in the upstream segment during the period 2006 to 2011.

Abstract

Soil affected by erosion will be carried by the flow of surface water into the river and would enter into the reservoir. This causes siltation of reservoirs that have done studies to estimate the amount of erosion rate in this case performed on Dawuhan Reservoir Catchment Area, Gondang Reservoir, and Nglambangan Reservoir, Bengawan Solo River Basin. One method often used in measuring the level of vulnerability to erosion is a method of USLE (Universal Soil Loss Equation). Erosion prediction with USLE method can also use GIS in its calculations. Geographic Information System (GIS) is a spatially-based technologies that are very popular today. Utilization of GIS-based spatial modeling pixels as a tool in predicting erosion can help the accuracy of the data generated, especially on lands that have a complex topography. The results of the analysis can be concluded greatest erosion rate occurred in the catchment areas of Nglambangan Reservoir with 75,327.93 tons / year with erosion rate27,18 tons/Ha/year. The rate of erosion found on the location of the second largest Gondang Reservoir with a total annual erosion rate of 7,347.77 tons / year with erosion rate 3,08 tons/Ha/year.

Abstract

Water of the Riam Kanan reservoir is used for irrigation, the supply of raw water, fishery, and hydro-powered,and transportation, etc. Domestic activities of domestic , agriculture, livestock and gold mining gold in the catchment area of Riam Kanan and acitivity fishery activities in the reservoir could be may degrade its water quality .The objective of this research is to know find out more on the pollution potential from catchment area and fishery activity, the characteristics of water quality , the trophic status and stratification of Riam Kanan reservoir. The research was conducted in May, 2009 and August, 2009. The descriptive study method applied had collected secondary data and water samples for analysed analysis. Evaluation was done based on PP no 82/2001 (Government Regulation no 82/2001) and trophic status according to the criteria stated in KepMen LH No:28/2009. Research results on pollution emission potential in the Riam Kanan Reservoir comprised: total Nitrogen 488 kg/day, and total phosphate 158 kg /day, and BOD 3,394 kg/day respectively. The conclusion of It can be concluded that water quality in the Riam Kanan reservoir suitable is in conformity with the criteria of Class 1 (PP 82/2002). The trophic status throphic was identified in the range of mesotrophic - eutrophic or medium fertile. The Stratification of Riam Kanan reservoir is oligomictic.
