Abstract

Rainfall data is crucial in water resources management, particularly associated with its quantity, quality, and spatial and temporal availability in a basin. This study aims to assess the feasibility of Global Precipitation Measurement (GPM) satellite rainfall data to represent rainfall in the Wampu basin. The observed and the GPM rainfall data were collected for 2001 – 2022. Rainfall data from observations and satellites are classified into seven rainfall depth classes with an interval of 10 mm for each class. The GPM was calibrated by determining each class’s correction factor (CF). Calibration is carried out by adjusting the CF value until the difference between the probability of occurrence of satellite and observation data for 2001 – 2017 shows a minimum value. The accuracy of the yielded CF was then validated by evaluating the estimated rainfall from the GPM with the observed rainfall for 2018 – 2022. The results show that the CF of GPM varies from 0.9 – 1.012 for rainfall intervals 0 – 10 mm, 10 – 20 mm, 20 – 40 mm, 40 – 50 mm, 50 – 100 mm, 100 – 110 mm, and >110 mm, respectively. Then, the validation results show an “Excellent” level of accuracy between the corrected GPM and the observed data.

Abstract

Central Sediment Sump is the largest sedimentation pond in the gold mine of PT. Bumi Suksesindo. Central Sediment Sump accommodates sediment from region Central Waste Dump (CWD), Pit E, and Pit B West. There is an increases in ore production began in 2018 makes the mining rate up to 8,1 million tons/year. This result increased sediment rates that are accommodated by Central Sediment Sump. The evaluation in this study is based on the amount of dredged sediment volume during 2018 with the volume of sediment that has been accommodated in the Central Sediment Sump. The volume of sediment that came from erosion in the Central Sediment Sump catchment area will be accommodated in the Central Sediment Sump. Dredged sediment volume depends on the bucket size excavators, excavator cycle times, and excavator work times. Excavator work time concern with the time needed to move the sediment volume that is already determined. The results evaluation of dredging sediment will describe sufficient whether or not sediment dredging in 2018 to dredge the sediment accommodated in Central Sediment Sump. Based on the results of this study the volume of sediment accommodates in Central Sediment Sump is 2.004.551,730 m3. Dredged sediment volume during 2018 is 11.755,310 m3. Therefore dredging sediment in 2018 insufficient to dredge all the sediment accommodates in Central Sediment Sump. Central Sediment Sump merupakan kolam pengendapan sedimen terbesar di Penambangan Emas  PT. Bumi Suksesindo. Central Sediment Sump menampung sedimen dari kawasan Central Waste Dump (CWD), Pit E, dan Pit B West. Adanya peningkatan produksi bijih mulai tahun 2018 menjadikan laju penambangan hingga 8,1 juta ton/tahun. Peningkatan ini mengakibatkan meningkatnya laju sedimen yang ditampung Central Sediment Sump. Evaluasi yang dilakukan pada studi ini berdasarkan pada jumlah volume sedimen terkeruk  selama tahun 2018 terhadap volume sedimen yang tertangkap di Central Sediment Sump. Volume sedimen yang berasal dari hasil erosi di daerah tangkapan air Central Sediment Sump akan tertangkap di Central Sediment Sump. Volume sedimen terkeruk tergantung pada ukuran bucket excavator, waktu siklus excavator, dan waktu kerja excavator. Waktu kerja excavator menggambarkan waktu yang diperlukan untuk memindahkan volume sedimen yang sudah ditentukan. Hasil evaluasi pengerukan sedimen akan menggambarkan cukup atau tidaknya pengerukan sedimen tahun 2018 untuk mengeruk sedimen yang tertangkap di Central Sediment Sump. Berdasarkan hasil studi ini diperoleh volume sedimen yang tertangkap di Central Sediment Sump sebesar 2.004.551,730 m3. Volume sedimen terkeruk selama tahun 2018 sebesar 11.755,310 m3. Sehingga pengerukan sedimen tahun 2018 tidak mencukupi untuk mengeruk seluruh volume sedimen yang tertangkap di Central Sediment Sump.

Abstract

In the simulation using HEC-RAS 5.0.7 the part to be simulated is the condition of the Malahayu Dam which collapsed due to 7 conditions causing inundation in the downstream area of the Malahayu Dam. Obtained from 7 conditions of dam collapse, the overtopping collapse scenario is the most extreme collapse scenario with an inundation area of 143.54 km2 with a maximum flood inundation height of 19.943 m. The purpose of this dam collapse simulation is to get the most extreme inundation so that in the next process of the inundation, the calculation of economic losses will be carried out with the help of the InaSAFE application. Losses resulting from the Malahayu Dam collapse scenario cover 53 villages from 6 sub-districts so that the evacuation victims reached 22400 people. With this amount, it can be determined that the Malahayu Dam is a dam with a hazard level 4, which is very high. The estimated losses incurred as a result of this collapse reached Rp. 515,521,114,788. The purpose of this study is to determine the level of danger of a dam, to know the characteristics of the flood, and to know the losses caused by flooding due to dam collapse.

Abstract

The Prijetan Dam was the first dam built in Indonesia in 1910 – 1916 by the dutch east indies government. This dam was built on the Prijetan River which is located in Sumbergempol Village, Kedungpring District, Lamongan Regency, East Jawa Province. Considering the age of the Prijetan Dam which is more than 100 years old, further analysis are needed on the impact of the dangers that can be caused by the break of the Prijetan Dam. Dams break is the collapse of part or all of the main dam causing the dam to be unable to function again. Dam breaks mostly occur due to overtopping or piping. From the simulation of the dam break of the Prijetan Dam using the Zhong Xing HY21 software, it was found that the largest floods occurred in the bottom piping scenario with the condition of the floodwater level reservoir. The area of the floods reached 26,607 km2 with a maximum flood depth of 6,880 m. The floodsspread to 38 villages located downstream of the Prijetan Dam with an estimated 11.412 people at risk Bendungan Prijetan merupakan bendungan pertama yang dibangun di Indonesia pada sekitar tahun 1910 - 1916 oleh pemerintahan Hindia Belanda. Bendungan ini berdiri diatas Sungai Prijetan yang terletak di Desa Sumbergempol, Kecamatan Kedungpring, Kabupaten Lamongan, Provinsi Jawa Timur. Mengingat usia Bendungan Prijetan yang lebih dari 100 tahun, maka diperlukan analisa lebih lanjut mengenai dampak bahaya yang dapat ditimbulkan oleh kegagal Bendungan Prijetan. Kegagalan bendungan yang dimaksud ialah runtuhnya sebagian atau seluruh tubuh bendungan yang menyebabkan bendungan tersebut tidak dapat berfungsi kembali. Kegagalan atau keruntuhan bendungan paling banyak terjadi akibat overtopping ataupun piping. Dari hasil simulasi keruntuhan Bendungan Prijetan menggunakan software Zhong Xing HY21, didapatkan banjir terbesar terjadi pada skenario piping bawah dengan kondisi tampungan waduk muka air banjir (MAB). Luas genangan banjir yang terjadi mencapai 26,607 km2 dengan kedalaman maksimum 6,880 m. Genangan banjir menyebar ke 38 desa yang berada di bagian hilir Bendungan Prijetan dengan perkiraan 11.412 penduduk terkena risiko.
