Abstract

Muara Enim adalah salah satu Kabupaten di Sumatera Selatan. Untuk mendukung majunya pertanian di wilayah ini perlu irigasi yang baik. Lokasi di Desa Pandan Enim ini dari sumber air, oleh karena itu perlu bantuan kincir air ke saluran irigasi. Anda juga harus merencanakan dimensi untuk menampung air irigasi yang dihasilkan dari roda kincir air dan perhitungan yang sesuai.Kincir air merupakan sarana untuk merubah energi air menjadi energi mekanik yang berupa putaran poros kincir. Ada berbagai cara untuk memanfaatkan energi air salah satunya dengan menggunakan kincir air. Dalam perancangan kincir air yang ditentukan diameter luar yang dirancang berdasarkan ketinggian lokasi, jarak sisi bagian atas kincir dengan ujung saluran air, serta jarak antara sisi bawah kincir dengan saluran pembuang.Diameter dalam kincir yang dirancang mempertimbangkan volume air yang dapat ditampung oleh sudu. Kincir Air efisien dibuat dengan diameter 2 m. Perhitungan diketahui dengan kecepatan aliran air yang dihasilkan kincir air sedangkan untuk volume putaran 16 sudu yang dihasilkan sebesar 57,63 liter/det pada kecepatan aliran air 8,54 m/det dan luas area persawahan yang dialiri kincir air seluas 73,51 Ha.

Abstract

PDAM Tirta Musi Palembang is a government-owned enterprise engaged in water treatment services,where water that is not dirty is processed and converted into clean water that is ready and suitable forhuman consumption. The increase in annual population has an impact on the increasing growth in thenumber of customers who need clean water. However, the Water Treatment Plant (WTP) or WaterTreatment Plant (IPA) still does not provide full services to all city environments, one of which is at thePalembang City Form WTP. The source of WTP processing comes from the Borang River and intake 1 ilir.The customer population is projected to increase to 22,434 in 2023 based on Geometric analysis with acalculation of customer needs of 218.04 liters/second. The pump used at WTP Borang has a capacity of200 liters / second and uses 2 pumps, so WTP Borang can still meet customer needs. The amount of waterdischarge required during maximum days and peak hours is 239.84 liters / second and 327.06 liters /second respectively. With this situation, it is predicted that the community's clean water needs in 2023 canbe fulfilled by WTP Borang.

Abstract

Rice fields that rely mostly on rainwater for irrigation are known as rainfed rice fields. Only the wet season yields rice fields like this one. Because of the heavy rains throughout the rainy season, agricultural land's water supply is not a concern. But during the dry season, when the water supply is getting smaller, the requirement for water for plants becomes a complex issue. This study aims to find out whether the rainfall currently available can satisfy the water needs of rainfed rice fields in Karya Mulia Village, Sematang Borang District, Palembang City, and to optimize the water supply. The following was discovered by the study's findings: water balance of discharge of water availability and water requirement for rainfed rice fields in Karya Mulia Village, which has a land area of 58 Ha, there is a water balance value of 23.711 mm per hari, which meets the water balance requirement for one growing season of rice plantsIn order to be optimal in the second growing season, it can be planted with crops that balance the availability and water demand at 10.844 mm/day.

Abstract

Clay soil subgrades have high pore water characteristics, which is a unique problem for civil structures such as buildings and road pavements. Lime contains compounds such as the element Calcium Oxide (CaO) of 79.43%. In reaction with clay minerals or other minerals, lime forms a strong calcium silicate gel that binds to soil particles. Different types of lime mixtures used are 0%, 12%, 15%, and 18% to soil weight with 28 days of soaking for four (4) days. From the two tests that have been carried out, namely soil compaction (Standard Proctor) and UCS (Unconfined Compression Streght) Soaked and Unsoaked, the optimum values obtained in soil compaction (Standard Proctor) and UCS (Unconfined Compression Streght) Soaked and Unsoaked are in the variation of soil addition + 18%. In the soil compaction test (Standard Proctor), the dry volume weight was 1.744 gr/cm3 and the optimum moisture content value was 16.03% and in UCS (Unconfined Compression Streght) Soaked the largest Qu value was 1.116 kg/cm2, and UCS (Unconfined Compression Streght) Unsoaked the largest Qu value was 2.714 kg/cm2.

Abstract

The clay soil used in this study came from Tebing Kawat Village, Talang Ubi District, Pali Regency, South Sumatra Province. The soil sample used was disturbed soil. Soil Stabilizer was used as a mixture to increase the bearing capacity of the soil with a mixture variation of 0%, 6%, 12%, and 18% with a curing time of 0, 7, 14 days in the compaction test (standard proctor) and unconfined compressive strength (unconfined compressive test). Soil property index tests include water content (w), specific gravity (Gs), liquid limit (LL), plastic limit (PL), sieve analysis soil volume weight test mechanical tests include compaction tests (standard proctor) and unconfined compressive strength tests (unconfined compressive test). From the test results obtained the value of the original soil water content of 37.87% the value of the water content after being given a mixture of 28.71%, 19.865%, 13.66%, the specific gravity of the original soil 2.59, the specific gravity after being given a mixture of 2.62, 2.67, 2.74, the liquid limit of the original soil was obtained 48.89 after being given a mixture to 46.67, 43.49, 39.06, while the plastic limit test of the original soil 38.83 given a mixture decreased 32.72, 26.12, 17.84. The results of the sieve analysis of the percentage passing sieve No. 200 with the addition of soil stabilizer made the soil condition granural while the saturation and porosity values were 111.60% and 42.90%, meanwhile the results of the maximum dry volume weight compaction test at 14 days of curing time were 1.452 with a mixture of 18% and the optimum water content decreased by 37.53% to 27.53% with a mixture of 18%, the qu value was 1.9425 and cu was 0.97125 at a mixture of 18%.
