Abstract

Drainage is one aspect that is meaningful in supporting the infrastructure of an area or region. This study aims to determine the existing condition of the channel and plan the dimensions of the drainage channel that can accommodate flood discharge. This research was carried out in several stages. The first stage, data collection in the form of secondary data, then in the second stage, data analysis is carried out, namely hydrological analysis and hydraulics analysis and the third stage is carried out planning channel dimensions with a trapezoidal cross section. From the results of the analysis and calculations, it was found that the flood discharge of the left segment channel was Qr5 th = 4.3359 - 25.6183 m3 / sec and Qr10 th = 4.9244 - 29.0951 m3 / sec and the flood discharge of the right segment channel Qr5 th = 3.9575 - 9.4389 m3 / sec and Qr10 th = 4.4946 - 10.7199 m3 / sec. In the dimensions of the drainage channel, the left segment has 7 channel segments with a cross-sectional width of the channel (B) = 3.50 m - 5.00 m and a channel depth (H) = 1.30 m - 2.80 m, while the right channel segment has 6 channel segments with a cross-sectional width of the channel (B) = 4.00 m - 5.00 m and channel depth (H) = 1.50 m - 3.00 m. Abstrak Drainase merupakan salah satu aspek yang berarti dalam mendukung infrastruktur suatu wilayah ataupun kawasan.

Abstract

Purwosekar village does not have an effective clean water distribution system. Sumber Jenon is located about 3.1km from Purwosekar village, precisely in Gunungronggo village, Tajinan sub-district. Sumber Jenon has potential for continuous water availability throughout the year, from the measurement of instantaneous discharge in getting potential from Sumber Jenon water of 481 liters/det. Tajinan sub-district consists of 12 villages, one of which is Purwosekar village. In 2024 Purwosekar village has a population of 4,786 people, while the projection of 2030 is 5,414 people. The clean water demand taken is 80 l/person/day in accordance with the minimum service standard for rural water. The water demand of the population in Purwosekar Village in 2024 amounted to 6.38 l/dt, in 2030 it amounted to 7.22 l/dt. Pipe network planning is based on water demand in 2030 using epanet 2.0 software. Clean water distribution in Purwosekar Village requires 6,978 meters of pipe, with pipe diameters varying from 2 inches (60mm) to 6 inches (165mm). The pipe used is PVC pipe with a pipe roughness coefficient of Hazen William 120. The length of pipe required for a diameter of 6 inches (165mm) is 1452m, diameter 5 inches (144 mm) 1867m, diameter 4 inches (140mm) 1345m, diameter 3 inches (89 mm) 1281m and diameter 2 inches (60mm) 1033m.

Abstract

Sampit River is part of the Mentaya catchment area, located in the East Kotawaringin Regency, Central Kalimantan, Indonesia. Sampit River is generally used as a water supply for domestic, industrial, and livestock needs. The Mentaya River water balance shows that for the year 2030 projection, the Sampit River is expected to experience a deficit, specifically during the first period of the month of October. This research was conducted using the SSP 1 2.6 climate change scenario. In this scenario, it is estimated that rainfall will change from +2.282 to +1.020% and increase in temperature ranging from 0.441-0.793 oC within the period 2021-2030 to 2041-2050. The calculation of 90% dependable flow shows climate change impacts the period of the year 2030 to 2050 when compared to the existing dependable flow. Likewise, the 95% dependable flow for river maintenance, also increases. The research concludes that the water balance endures climate change impact and the calculated deficit remains the same for the first period of the month of October. The results of the water balance show that until 2050 climate change had not impeded negative effects but cautionary efforts must be taken as there an increasing deficits for the years 2040 and 2050.

Abstract

Daerah Irigasi (DI) Saddang berada di Kabupaten Pinrang Propinsi Sulawesi Selatan dengan luas areal 61.198 Ha, yang mendapatkan air dari Bendung Benteng memiliki debit rata-rata 319 m3/dt dan debit Andalan yang berfluktuasi antara 39,8 – 328,1 m3/dt. DI Sadang memiliki Pola Tata Tanam (PTT) eksisting Padi-Padi Palawija dengan awal tanam yang berbeda-beda pada setiap primer/sekundernya. Hasil perhitungan neraca air dengan PTT eksisting tanpa memperhitungkan debit pemeliharaan didapatkan areal yang terairi seluas 48.958 Ha di MT1 61.198 Ha di MT2 dan 61.198 ha di MT3 atau areal terairi 61.198 Ha dengan intensitas tanam 280%. Guna mengoptimalkan air yang ada maka dibuat PTT rencana, dengan mengeser awal musim tanam pada berbagai variasi. Dari hasil perhitungan dengan PTT rencana Padi-Padi-Palawija didapat bahwa  air yang ada masih cukup untuk mengairi areal seluas 61.198 dengan intensitas tanam 300%. Kelebihan air yang ada, jika di manfaatkan untuk penambahan areal, didapat tambahan areal yang bisa terairi seluas 47.016 Ha dengan intensitas tanam 300%. Jadi secara perhitungan total, didapat areal terairi seluas 108.214 Ha dengan intensitas tanam 300%. Perhitungan ini juga tanpa mempertimbangkan debit pemeliharaan. Sesuai dengan peraturan yang ada, debit pemeliharaan tetap harus dialokasikan untuk kelestarian sungai. Perhitungan debit pemeliharaan dengan menggunakan metode Tennant, didapatkan debit pemeliharaan Bendung benteng adalah 31,9 m3/dt. Dari hasil analisa neraca air dengan memperhitungkan debit pemeliharaan didapatkan areal yang terairi dengan pola tanam Padi-Padi-Palawija adalah seluas 61.198 Ha di MT1 61.198 Ha di MT2 dan 16.523 ha di MT3 atau areal terairi 61.198 Ha dengan intensitas tanam 227 %. Terjadi penurunan intensitas tanam sebesar 53 % di banding pola tata eksisting.ABSTRACTThe Saddang Irrigation Area is located in Pinrang Regency, South Sulawesi Province with an area of 61,198 ha, which gets water from the Benteng Barrage, which has an average discharge of 319 m3/s and a fluctuating dependable flow between 39.8 - 328.1 m3/s Saddang Irrigation Area has an existing crop pattern of Paddy Paddy Palawija with different planting starts for each primary/secondary. The results of the calculation of the water balance with the existing cropping pattern without considering maintenance flow as an obligation that must be fulfilled, have a result it can irrigate 48.958 ha in Planting Season 1, 61.198 ha in planting season 2, and 61.198 ha in planting season 3, or irrigated 61.198 ha with 280% crop intensity. To optimize the available water, a planned crop pattern was created, by shifting the beginning of the planting season to various variations. From the results of calculations with the cropping pattern of the Paddy-Paddy-Palawija, it was found that the available water was still sufficient to irrigate an area of 61.198 ha with 300% crop intensity. If the excess water is used for additional areas, an additional area that can be irrigated is 47.016 ha with 300% crop intensity. So in the total calculation, the irrigated area is 108,214 ha with 300% crop intensity. This calculation is also without considering maintenance flow as an obligation that must be fulfilled. Under existing regulations, the maintenance flow must be allocated for river conservation. Calculation of the maintenance flow using the Tennant method, it is found that the maintenance discharge of the Benteng Barrage is 31.9 m3/s. From the results of the water balance analysis with maintenance flow as an obligation that must be fulfilled, from the calculation results obtained that the irrigated area with the Paddy-Paddy-Palawija cropping pattern, was 61.198 ha in planting season 1, 61.198 ha in planting season 2, and 16.523 ha in planting season 3, or 61.198 ha with 227% crop intensity. There was a 53 % decrease compared to the existing crop intensity.
