Abstract

Erosion and sedimentation on the upstream river flow area have caused various problems along the Citarum River in West Java. Many parties, both governmental and private, have and should continue to make various efforts to overcome the problem both in the form of technical and non technical control in all parts of the river basin both upstream and downstream. Sedimen control in the upstream land area is one method developed because this way directly reduces the erosion at the exact location. The physical model of green sabo technique in area is an example of a test run for erosion control in the upstream region by demonstration plot. This method uses the treatment of green sabo technique that is straw method, coco fiber net, mulch, and natural treatment. The purpose of model implementation is to measure and compare the rate of erosion of various treatments as mentioned earlier. Based on calculations in the field consisting of soil compilers, rain, and slope, it is known that the straw method is the best treatment medium in controlling erosion on the land area. The second best control is coconut (mesh) nets followed by natural treatment, and mulch method application. Based on its function to reduce the amount of surface water flow known that mulch is a method that produces a largest surface flow.

Abstract

Mega-eruption of Merapi Volcano 2010 is a large-scale explosive eruption, destroying lava dome, removing cloud columns as high as 4 kilometers and bursts of in various directions at the volcano foot. Approximately 140 millions m3 of pyroclastic material spread through the 13 major rivers that source from Merapi. Lahar flow occurred in almost every river basin located beneath the active cone of Merapi. As a result of the lahar flow, as many as 77 of the 264 units of the sabo dam in the Merapi area were damaged or washed away by the lahar flows. The sabo dam controls the flow of lahar built up across the river channel to hold, accommodate and drain some of the material or sediment in order to carry the flow and pass water downstream. This study was conducted to find the cause of sabo dam damage, and the right solution after the eruption of Merapi 2010. The method used in qualitative descriptive approach. The results of this study were to revitalize sabo dam as lahar flow controller and as a reference in reviewing the master plan of a lahar flow control system in other volcanic areas.

Abstract

Special treatment for watershed management was needed due to severe of watershed condition in most regions in Indonesia. The treatment should be directed to comprehensive changes of management paradigm for all aspects in it. Those were indicated by the increasing of disasters around the watershed, such as floods, droughts, landslides, erosion and increased of sediment transported by the river basin. The increasing of sedimentation which occurs in the river flow will disrupt the performance of existing hydraulic structure in the river. The event could be monitored by hydrological data, especially with the continuously and accurately of discharge and sediment data. In order to solve the problem, sediment data quality control model was needed. The purpose of this research is to determined suspended sediment data quality control model, in order to have continuous and quality guaranteed of sediment transport data. The scopes of this sediment data quality control were making criteria and sub, determining rank priority between criteria and sub, arranging scoring form, trial and error, finalization. The model consists of three main stages, there are measurement of discharge and taking sediment sample (QC1), drawing of sediment rating curve (QC2), and conversion of discharge data to sediment transport (QC3).

Abstract

Water resources infrastructure development requires a careful planning, one of which requires hydrological analysis. The accuracy of hydrological data is influenced by the method, operator/observer, and the performance of the measuring instrument. Up date water resources management agencies in Indonesia have conducted observations of discharges in the rivers or channels, by observing Water Level (WL) at the gauging station. WL values can be read directly or by using an automatic WL meter tools (AUTO) which have been finstalled in many gauging stations. Therefore, it is necessary to evaluate the AUTO performance that can be done through calibration in the laboratory. This paper evaluates the performance of several types of AUTO (AWLR, AWLL buoyance, and AWLL pressure) by comparing themeasurement results with the standard/reference tool i.e, using a calibrator instrument, so that the values of the measurement error and uncertainty were obtained. Both parameters were used to determine the performance of AUTO devices because they are related to the level of accuracy and precision. Based on the results, it was found that AWLR produces the best level of accuracy and precision, followed by AWLL pressure, and AWLL buoyance.

Abstract

Changes in land use of tropical peat will lead to the release of carbon (C) on the condition that initially stabilized, and resulting in land subsidence. Peatland clearance which is preceded by the construction of the canals will cause the ground water table in peatlands fell. Along with that, the subsidence occurs, which at the beginning of peatland reclamation rate of decline very fast and gradually slow down over time with reduction of organic materials that decompose or burn. Therefore, knowledge of the rate of subsidence is very important to plan drainage and optimal use of peat land in order to preserve the peat. The method or scientific approach used is the assessment directly, include: measurement of the location of groundwater levels, land subsidence at various existing condition of land in different locations, peat soil sampling and calculation with the empirical formula. The calculation of land subsidence using average data groundwater levels during the dry season, in addition to the types of land cover took into account as well. This paper presented the results of the analysis of land subsidence and the projected decline in the next 50 years peatlands in Sei Ahaz, Kapuas, Central Kalimantan and Sungai Buluh, Tanjung Jabung, Jambi and comparative results between the two locations. The implications of this study indicate that the regulation of groundwater levels will control land subsidence.

Abstract

Pile breakwater is an alternative coastal structure to prevent coastal erosion considering the economic and technical aspect. An improved design for pile breakwater is proposed here. Our goal is to develop an assessment tool in planning the implementation of pile breakwater. This tool is based on numerical model that has been verified with physical model result. The wave spectrum show that the numerical model is able to simulate the wave as same as the physical model with overestimation. It also points out that the simulation with wave period (T) = 2.5 s has more significant noise than the simulation with wave period (T) = 2 s. In general, the numerical model has high accuracy for predicting incident wave height (Hi), transmitted wave height (Ht) and transmission coefficient (KT) with error below 1 % RMSE. Xbeach is also able to simulate pile breakwater with high accuracy especially for two or three row arrangement with width gap 0.3 m. Even so, the numerical model have limitation regarding wave phase and wave through irregularity. Pile breakwater is an alternative coastal structure to prevent coastal erosion considering the economic and technical aspect.
