Abstract

This paper presents the results of the study of one of the alternative decision support systems in determining the priority of irrigation maintenance. One of the obstacles in maintaining irrigation assets is the limited budget, hence the need for priority maintenance of irrigation. Batu City as an agricultural area, has not applied objective assessment criteria in determining the priority scale of irrigation asset maintenance to support the success of agriculture. Especially the irrigation area of Kali Brantas Sub Watershed which is the downstream area of Batu City, there are still many damaged irrigation assets infrastructure. This study aims to determine the priority of irrigation maintenance of Kali Brantas Sub Watershed Batu City. Analysis using Simple Additive Weighting method with the following stages: The assessment of each criterion directly in the field (Physical Condition, Functioning, Service Area and maintenance cost) according to Regulation of Minister of Public Works No. 13 / PRT / M / 2012, , determine the rating of each alternative match, normalization of alternative value of each criterion and ranking of normalization product with weight of importance. The result of the analysis shows that irrigation infrastructure which become the first priority in irrigation maintenance activity of Kali Brantas Sub Watershed Batu City is Genengan Dam. For second priority up to five consecutive are; Bend Beji I, Beji II, Ngukir Mranak II and Ngukir Mranak I Dam..

Abstract

The central government through the Directorate of Environmental Sanitation Development (PPLP) of the Directorate General of Human Settlements of the Ministry of Public Works and Public Housing participated in the implementation of drainage of Surabaya by providing assistance for the construction of Greges pump house. The pump house Greges as one of the pump house located in Surabaya, is one of the drainage system controllers around Bozem Morokrembangan area especially the flow of water along the Greges channel which is also an outlet for several channels. In the aid of the pump house choose to use Genset as the main power source (SDL). While the Government of Surabaya always wants the use of SDL from PLN. The purpose of this study was to analyze the use of SDL to meet the needs of the Greges Pump House by performing the cost analysis required for the Greges pump house for the use of Genset and PLN power sources, and determining the better SDL selection that would be used to meet the needs of the Greges pump house. Based on the analysis of costs, the use of generators is better than PLN in the investment cost analysis. Based on PLN operational cost analysis is better than generator. In the first year period the total cost for the use of PLN is Rp. 5.102.223.905 greater than the generator Rp. 4.789.084.970,16,, in the second year the cost of using PLN approaches the generator cost, and on the third and so the use of generator is higher than the PLN.

Abstract

Tujuan dari penelitian ini untuk memberikan analisa debit aliran pada DAS Rejoso Kabupaten Pasuruan pengaruh perubahan tata guna lahan dan curah hujan menggunakan HEC-HMS (Hydrology Engineering Center-Hydrologic Modeling System).  Penutupan lahan yang digunakan dalam analisis ini terdiri dari peta penurupan lahan kabupaten pasuruan tahun 2016 serta penutupan lahan sesuai Rencana Tata Ruang dan Wilayah (RTRW) Kabupaten Pasuruan yang diterbitkan oleh Badan Perencanaan Pembangunan Daerah (BAPPEDA) Kabupaten Pasuruan. Curah hujan masa depan diproyeksi dengan menggunakan model CSIRO dengan skenario RCP 4.5 yang di downscalling menggunakan metode bias correction. Hasil pemodelan HEC-HMS, limpasan pada penutupan lahan sesuai RTRW 2009-2029 dengan curah hujan proyeksi tahun 2029 cenderung lebih besar daripada penutupan lahan tahun 2016. Kenaikan curah hujan dengan rata-rata 17% mengakibatkan peningkatan limpasan rata-rata sebesar 4,27% pada penutupan lahan tahun 2029. Dari hasil pemodelan skenario 2 dan skenario 3 didapatkan hasil bahwa perubahan curah hujan lebih berpengaruh dibandingkan perubahan tata guna lahan terhadap hidrograf aliran DAS Rejoso.

Abstract

Floods in Kabupaten Situbondo and Bondowoso were caused by overtopping of Sampean River. This paper discusses a study on control of Sampean River by utilizing the potential upstream reservoir. The upper reservoir was used to receive part of the rain water, so that the discharge to the main river could be reduced and the stored water can be used as water resource and water conservation. The discharge through the Sampean River was much greater than the flow capacity. The results of the survey and analysis indicated that eleven locations were potential for reservoir. These locations were dam sized sites in the main river, and ten locations in the tributaries of small dam size. The Tasnan dam had a potential water storage capacity up to 3.1 million m3, whereas the small dams were of 100,000 to 500,000 m3. By analyzing the 50-year raining return period, the Tasnan dam potentially reduced the floodi as much as 99.5 m3/s. The small dams of Walidono 1, Walidono 2, and Cangkring can reduce the discharge up to 5.9, 3.9, and 2.2 m3/s, respectively. Meanwhile, the small dams of Mandiro, Selolembu, Pandak, Pakis, Gubri 1, Gubri 2, and Cabang only had very small potential capacities in reducing the flood.
