Abstract

Sistem perpipaan berfungsi untuk mengalirkan zat cair dari satu tempat ke tempat yang lain. Aliran terjadi karena adanya perbedaan tinggi tekanan pada kedua tempat, yang biasa terjadi karena adanya perbedaan elevasi muka air atau karena digunakannya pompa. Aliran fluida didalam pipa mengalami kehilangan energi seiring dengan panjang pipa yang dilalui, yang diakibatkan kekasaran pipa, panjang pipa, diameter pipa, dan  jenis fluida.         Tujuan dari penelitian ini adalah untuk mengetahui efek kekasaran dinding pipa terhadap kecepatan aliran dan untuk mengetahui perbedaan antara kecepatan aliran terhadap kekasaran dinding pipa jika menggunakan manometer manual dengan dengan software WaterCad V8i. Pada percobaan ini dilakukan dua percobaan, yaitu percobaan menggunakan manometer manual didalam laboratorium dengan berbagai macam variasi diameter dan jenis pipa yaitu pipa halus dan pipa kasar dengan percobaan menggunakan aplikasi WaterCad V8i. Pada percobaan pipa halus semakin besar nilai kecepatan aliran (0,792 m/s – 3,740 m/s) dalam pipa, maka nilai kehilangan energi (0,028 – 4,813)  juga akan semakin besar. Ini membuktikan bahwa kecepatan aliran berbanding lurus dengan nilai kehilangan energi. Pada percobaan pipa kasar semakin besar nilai kecepatan aliran (0,875 m/s –2,548 m/s) dalam pipa, maka nilai kehilangan energi (0,096 – 0,808)  juga akan semakin besar. Ini membuktikan bahwa kecepatan aliran berbanding lurus dengan nilai kehilangan energi. Bedanya dengan percobaan pada pipa halus adalah kecepatannya lebih besar, ini diakibarkan karena penampang bagian dalam pipa memiliki permukaan yang lebih halus dan memiliki luas penampang yang lebih kecil dibandingkan dengan pipa kasar, dan kecepatan aliran pada pipa kasar  rendah diakibatkan adanya gesekan dengan permukaan pipa yang kasar. Perbandingan menggunakan metode manual dengan menggunakan aplikasi Watercad V8i dari nilai regresi data manual dan data aplikasi (0,787 – 0,975), hasil perhitungan menggunakan aplikasi Watercad V8i; nilai kecepatan dan kehilangan energi yang diperoleh mendekati / memiliki hubungan langsung positip baik dengan nilai kecepatan dan kehilagan energi yang diperoleh dengan menggunakan metode manual.Kata Kunci: Kehilangan Energi, Jaringan Pipa, Watercad V8i Piping system serves to drain liquid from one place to another. Flow occurs due to the high difference in pressure in the second place, that usually happens because of differences in water level or by the use of pumps. Fluid flow in the pipe experience a loss of energy along the length of pipe that passed, which caused the pipe roughness, length of pipe, pipe diameter, and type of fluid.In this study, two experiments, the experiment using a manometer manually in the laboratory with a wide variety of diameters and types of pipe is smooth pipes and plumbing rough and experiments using V8i WaterCad applications.At the trial the greater smooth pipe flow velocity value (0.792 m / s - 3,740 m / s) in the pipeline, then the value of the energy loss (0.028 to 4.813) will also increase. This proves that the flow velocity is proportional to the rate of energy loss. At the trial the greater rough pipe flow velocity value (0.875 m / s -2.548 m / s) in the pipeline, then the value of the energy loss (0.096 to 0.808) will also increase. This proves that the flow velocity is proportional to the rate of energy loss. The difference with experiments on smooth pipe is greater speed, this diakibarkan because the cross section of the inner tube has a smoother surface and has a smaller cross-sectional area compared to the rough plumbing and rough pipe flow velocity at low due to friction with the rough surface of the pipe .Comparison using the manual method using Watercad V8i application of regression value of manual data and application data (0.787 to 0.975), the results of calculations using Watercad V8i application; the value of speed and energy loss obtained approaching / have a direct positive relationship both with speed and kehilagan energy value obtained using the manual method.Keywords: Loss of Energy, Pipeline, Watercad V8i

Abstract

 To optimize the planting of rice plants, groundwater is used as a source of water so that the water needs for agricultural land can be met. Groundwater, which is a source of water, is known to contribute greatly to agricultural production, especially in the dry season. The long-term goal of this research is to increase groundwater discharge using a water pump as a controller of water distribution, alternative energy in the form of solar energy is used to drive the pump engine. During this time the pump is driven by an oil-fueled engine (BBM) which produces CO2 emissions into the air. The use of non-fuel alternative energy is expected to help reduce CO2 emissions so far. The research method begins with a survey and field survey conducted by the groundwater irrigation network in the Pare-Pare district. then search along ground waterways and mark using GPS. Measuring discharge and analyzing the performance of solar water pumps. To optimize the planting of rice plants, groundwater is used as a source of water so that the water needs for agricultural land can be met.

Abstract

This study analyzes the potential and operational planning of the Tabulahan hydropower plant located at the Bonehau River, Periangan Village, Tabulahan District, Mamasa Regency, West Sulawesi. The project utilizes a water catchment area of 306 km² upstream of the dam and 324 km² downstream of the plant. The discharge analysis uses the Flow Duration Curve (FDC) method with the results showing adequate discharge availability. A reliable discharge of 22.80 m³/s was selected based on a reliability level of 85%-90%, with a design discharge of 8.97 m³/s for each turbine. For further planning analysis, the power generation discharge was set at Q50% (14.72 m³/second) and the river maintenance discharge (ecoflow) at Q95% (21.60 m³/second). With an installed power capacity of 10 MW, the Tabulahan hydropower plant is designed to optimize the potential of water resources with a sustainable approach.
