Abstract

This research aims to analyze behavior at the Bili-Bili Dam based on instrumentation data collected from the construction period to operation. The data used includes the results of measurements of horizontal deviation, changes in vertical height, and pore air pressure obtained through instruments such as sliding stakes, piezometers, and auto levels. The main focus of the research is to identify changes over time, address dam stability, and provide recommendations for mitigating the risk of structural failure. This research method involves collecting secondary data from measurement records from 1997 to 2023. Analysis was carried out using permit acceptance criteria based on ICOLD (International Commission on Large Dams) standards. The results of horizontal deviation measurements show that the largest movement occurs at the top of the dam, but is still within the design tolerance limits. Vertical measurements show the greatest elevation decrease (subsidence) in the central part of the dam, which remains in line with initial predictions based on geotechnical parameters. Meanwhile, pore water pressure measured via a piezometer shows a normal decrease in accordance with changes in reservoir water level. The research results showed that the freezing that occurred was mostly caused by consolidation of the rock fill material and hydraulic interactions between the water reservoir and the dam structure. However, several areas show anomalies that require further monitoring, especially on the left and right wings of the dam. In conclusion, the Bili-Bili Dam is still in a stable and safe condition. Recommendations include increased monitoring of area anomalies and strengthening the routine maintenance program to maintain long-term stability..

Abstract

This research aims to evaluate the level of sedimentation that occurs and its impact on the reservoir capacity. The data used includes bathymetry measurements in 2023, drift and bottom sediment discharge, as well as historical sediment inflow data. Analysis was carried out to calculate sediment volume, sedimentation rate, and changes in reservoir capacity. The research results show that the Bili-Bili Reservoir experienced a significant reduction in storage capacity from 1997 to 2023. The total sedimentation that occurred reached 50 million cubic meters, reducing the storage capacity from 375 million cubic meters to 325 million cubic meters. The actual sedimentation rate of 1.5 mm per year exceeds the initial plan. This condition means that the useful life of the reservoir, which was originally designed for 50 years, is estimated to only be able to last up to 19 years of the remaining life of the existing reservoir, which is faster than the design plan life. This impact not only reduces flood control capacity but also reduces the effectiveness of water supply. standard for society. Recommendations from this research include implementing catchment area management with conservation techniques such as reforestation and land use control, increasing the frequency of sediment dredging in reservoirs, as well as using sediment control building technology to reduce the entry of sediment material into reservoirs. The results of this research provide relevant information for sustainable planning and management of reservoirs so that their function remains optimal in the future.

Abstract

More frequent extreme rainfall can cause floods and landslides in some areas of Banten, especially in mountainous and hilly areas, The increase in air temperature in Banten tends to increase in recent decades. This can affect agricultural productivity and increase the risk of forest and land fires. Uncertain rainfall patterns can affect the agricultural sector and the availability of clean water in Banten, to overcome the impact of climate change, the Banten Provincial Government has taken several mitigation and adaptation measures, such as improving flood control infrastructure, planting mangroves in coastal areas, and implementing agricultural practices that are more resilient to climate change. The purpose of this study is to determine the model of the intensity and influence of climate variables on the intensity of rainfall due to global warming in the Cidanau watershed, Serang Regency, Banten Province. The methods used in this study are frequency analysis, probability, compatibility test and rain intensity analysis based on climate simulation. The results of this study obtained a model of the intensity of climate parameters that have the most influence on the intensity of rain for the simulation of 1 variable is air humidity (Rh) with the equation I (RH) = 166,10 X-0,666 , For the simulation, 2 variables are wind speed and air humidity (W-RH) with the equation I (W-RH) = 177,84 X-0,666 and the highest influence is the simulation of 3 variables of temperature, wind speed, and air humidity (T-W-RH) simultaneously with the equation I (T-W-RH) = 190,70 X-0,666.
