Abstract

Abstract: This study explores accuracy of short term rainfall disaggregation model by modeling rainfall runoff. Storm hydrographs show rapid responses to rainfall with a short time to peak. The spatial rainfall disaggregation process used multivariate daily rainfall (MuDRain) model on 4 manual rainfall rain gauges (MRR) and 3 automatic rainfall rain gauges (ARR) used as reference the hydrographs were satisfactorily modeled using the Hydrologic Engineering Centre–Hydrologic Modeling System (HEC-HMS). Parameter calibrations were done on case 1 that rainfall runoff modeling used the rainfall data from 7 rain gauges (MRR and ARR). Model validation (case 2) used the rainfall data from 3 rain gauges (ARR). The efficiency indexes of (case 1) and (case 2) are 0.97 and 0.74, respectively. Based on these preliminary findings, it could be suggested that rainfall disaggregation would be able to serve reasonably well in regulating basic hydrological functions.Key words: rainfall, runoff, disaggregation, MuDRain

Abstract

Banjir merupakan faktor yang mengakibatkan kerusakan infrastruktur jaringan irigasi pada daerah irigasi di aliran Sungai Jompo. Kerusakan tersebut berdampak pada kurang optimalnya kinerja jaringan irigasi. Oleh karena itu, dengan terbatasnya anggaran biaya rehabilitasi maka perlu dilakukan analisis prioritas rehabilitasi jaringan irigasi. Studi ini mengambil lokasi pada Daerah Irigasi (DI) yang berada di aliran Sungai Jompo, Kabupaten Jember, Jawa Timur. Penentuan prioritas rehabilitasi jaringan irigasi dalam penelitian ini menggunakan metode Simple Additive Weighting (SAW) dengan cara menentukan bobot masing-masing kriteria rehabilitasi yang meliputi kondisi prasarana, ketersediaan air, luas areal fungsional, dan produktivitas tanam. Selanjutnya melakukan normalisasi dan perangkingan setiap alternatif dari nilai prioritas. Hasil analisis prioritas rehabilitasi jaringan irigasi menggunakan metode SAW menyatakan bahwa daerah irigasi yang menjadi prioritas utama adalah DI. Bedus. Untuk prioritas kedua hingga kesembilan secara berurutan adalah DI. Arah III, DI. Sekar, DI. Pengarengan, DI. Polo, DI. Langon Patrang, DI. Sembah Kurung, DI. Jaki, dan DI. Sembah.

Abstract

Banjir bandang di Kabupaten Jember pada pergantian tahun 2006 merupakan salah satu bencana nasional yang membawa banyak korban. Kejadian banjir bandang di Kaliputih terus berulang, untuk itu keberadaan peta zonasi banjir sangat diperlukan untuk antisipasi sebelum kejadian. Tujuan dari penelitian ini adalah untuk melakukan zonasi tingkat kerawanan banjir bandang di sub-DAS Kaliputih dengan bantuan Sistem Informasi Geografis. Metode yang digunakan dalam penelitian ini adalah metode Weights of Evidence. Lima faktor diantaranya kemiringan lereng, tata guna lahan, kerapatan jaringan sungai, jenis tanah dan Normalized Difference Vegetation Index (NDVI) digunakan untuk membuat peta zonasi. Dari yang terkuat, parameter pengkondisi kerawanan banjir adalah jenis tanah latosol coklat dan regosol abu-abu, penggunaan lahan sawah, kemiringan lereng, penggunaan lahan rumah, NDVI pada nilai rendah, dan kerapatan jaringan sungai pada nilai rendah. Hasil yang didapatkan dari analisis menunjukkan sebesar 12,25% dari total wilayah di sub-DAS Kaliputih memiliki tingkat kerawanan banjir bandang yang sangat tinggi, 14,58% tinggi, 12,81% sedang sampai tinggi, 14,89% sedang, 16,98% rendah, dan 28,49% sangat rendah dengan nilai Area Under Curve (AUC) sebesar 80,0%.

Abstract

The southern region of East Java is located on the Indo-Australian plate. The shifting of these plates allows for earthquakes that trigger tsunamis to occur. The earthquake leads to the impact of a tsunami in several areas, one of which is Puger Sub-District, Jember Regency. The main economic activity of the Puger Sub-District is the fishery; hence significant local coastal communities are vulnerable to tsunami threats. This study aims to map the tsunami risk using a Geographic Information System. The tsunami hazard map used the analysis of the tsunami inundation map from the BMKG. Vulnerability and capacity maps were prepared based on BNPB Chief Regulations. Vulnerability is evaluated based on social, physical, environmental, and economic data. Capacity considers components of the institution, early warning and risk analysis or evaluation, disaster awareness education, reduction of basic risk, and preparedness. The hazard, vulnerability, and capacity maps are classified into five classes. The tsunami risk map is then derived by overlaying the three input maps. Results showed that the villages with very high risk are Puger Kulon and Mojosari at the coastal front areas, covering an area of 13.01% of the total regional area of the Puger Sub-District.

Abstract

Pipa pesat merupakan saluran penghubung antara bak penenangdengan turbin pada rumah pembangkit. Meminimalisir kehilanganenergi pada pipa pesat sangat penting untuk mengoptimalkanbangkitan energi listrik. Tujuan penelitian ini adalah melakukanoptimasi diameter dan tebal pipa pesat untuk mencari hasil yangpaling efisien, yang dikaji dari aspek hidrolika dan biayanya.Metode pemilihan pipa pesat yang optimal dapat ditentukanberdasarkan hubungan secara empiris, antara berbagai formula daridiameter dan tebal pipa pesat yang dinilai terhadap energi yangdihasilkan serta harga pipa pesat itu sendiri. Hasil penelitianmenunjukkan bahwa besar diameter berbanding lurus dengan besarenergi yang dihasilkan dan harga pipa pesat. Berdasarkanperbandingan, didapatkan diameter optimum pipa pesat sebesar0,45 meter dengan tebal 0,0018 meter yang dihitung menggunakanformula dari Moffat, serta daya bangkitan sebesar 52,16 kW danenergi sebesar 456.914,33 kWh per tahunnya dengan harga pipaIDR 3.610.900 per meter pipa pesat.Penstock is the connecting channel between the forebay and theturbine in the power house. Minimizing the energy loss in thepenstock is very important to optimize the generation of electricalenergy. The purpose of this research is to optimize the diameterand thickness of penstock to find the most efficient results, whichare examined from the aspects of hydraulics and costs. The optimalmethod of penstock selection can be determined based on theempirical relationship between the various formulas of the diameterand thickness of the penstock as assessed by the energy producedand the price of the penstock itself. The results showed that thediameter was directly proportional to the amount of energyproduced and penstock price. Based on the comparison, theoptimum diameter of the penstock is 0,45 meters with a thicknessof 0,0018 meters which is calculated using the formula fromMoffat, as well as a generation power of 52,16 kW and energy of456.914,33 kWh yearly with the price of IDR 3.610.900 per meterpenstock pipe.

Abstract

The Sub-watershed of Sampean Hulu, located on the slopes of Mount Raung is susceptible to erosion hazards. Erosion indicators have been observed in the irrigation channels, mainly due to frequent sedimentation, which compromises the irrigation infrastructure's optimization and water distribution. To address this, erosion monitoring using the Universal Soil Loss Erosion (USLE) model, along with GIS and remote sensing techniques, is essential. It was found that the irrigation networks associated with Clangap and Tamanan rain gauges are at higher risk due to intense rainfall. Maesan and Wonosari II rain gauges cover a larger irrigation network area, highlighting the need for erosion prevention measures. The dominant soil type, Tv, with a high clay content, is highly susceptible to erosion. Flat and gently sloping slopes have a lower risk compared to steeper slopes, while very steep and steep slopes pose higher erosion risks. Paddy fields and well-managed forest plantations have lower erosion hazards, while bare land and certain agricultural practices contribute to increased erosion risks. The analysis classified the erosion hazard into five classes, with the sub-watershed being predominantly low and very low susceptible to soil erosion. Implementing conservation practices, sustainable land management, and land use regulations are crucial for erosion prevention.
