Abstract

Dengan mengetahui kondisi permukaan tanah Kota Palembang yang relatif datar serta berawa sehingga ketika hujan dengan intensitas tinggi dan durasi lama, maka pengaliran limpasan air membutuhkan waktu cukup lama untuk menuju tempat pembuangan, terutama bila terjadi bersamaan dengan air laut pasang yang mengakibatkan aliran balik. Penanggulangan kondisi tersebut adalah dengan membangun kolam retensi. Kapasitas kolam retensi diketahui dengan analisis penelusuran banjir menggunakan Metode Kolam Retensi. Analisis hidrologi menggunakan Metode Rasional dan HSS Nakayasu. Analisis tersebut diperoleh debit runoff yang terjadi pada sub sistim DAS Kedukan. Berdasarkan hasil analisis, diketahui volume kolam retensi sebesar 72.072 m3 dengan luas kolam 2,5 ha yang terletak di wilayah administratif 5 Ulu, untuk kolam retensi di wilayah 3-4 Ulu volume kolam retensi adalah sebesar 24.156 m3 dan luas kolam 2,0 ha. Dan debit runoff untuk periode ulang 10 tahun yang dihitung dengan Metode HSS Nakayasu sebesar 1,82 m3 /detik untuk sub DAS 1 dan sub DAS 2 sebesar 0,61 m3 /detik.

Abstract

The phenomenon of development (swelling) of clay soil which causes various impacts on the construction of civil buildings, especially road construction, especially in the area of ​​South Sumatra where most of the area is swampy. One of the mixtures to improve soil quality can use lime and cement with certain levels. The research method is experimental in the laboratory. The results of the physical properties test, namely the Sieve Analysis to pass No.200, obtained a value of 82.70%, Density obtained a value of 2.523, Liquid Limit obtained a value of 76.84%, Plastic Limit obtained a value of 44.78%, Plasticity Index obtained a value of 32.06%. The results of mechanical properties testing, namely Standard Density, obtained a Yd value of 1.216 gr / cm3 at the optimum water content of 37.20%, laboratory CBR obtained a CBR value of 3.73%. The CBR test results of the original Soil Laboratory showed that the CBR value was 3.73%. The results of laboratory CBR testing with the addition of 2% lime + 2% cement obtained CBR values ​​of 16.46%. The results of laboratory CBR testing with the addition of 4% lime + 4% cement obtained CBR values ​​of 28.60%. The results of laboratory CBR testing with the addition of 6% lime + 6% cement, obtained a CBR value of 34.48%.

Abstract

The purpose of this study was to compile a technical study of planning for the construction of 3R TPS on Sabira Island, Seribu Islands Regency, DKI Jakarta Province. The research method is a quantitative method. The types of surveys carried out are polygon and rate generation. The plan for the construction of the Sabira Island 3R TPS is recommended in an available location with a land area of ±375 m2 or 15 m x 25 m. The condition of Service and Waste Management on Sabira Island has a weighting score with a total score of 14. This means that the criteria for service and waste processing locations for the construction of 3R TPS on Sabira Island are recommended in the available locations. Of the four waste processing technologies on Sabira Island that were assessed using the SWOT method, it was concluded that composting was the one that exceeded the median score for both internal and external environmental factors. The number of collecting vehicles for motorbike carts on Sabira Island is 4 trips/day (1 (one) unit of existing motorbike cart is suitable for use). The loading rate to be processed at the 3R TPS on Sabira Island is 0.542 m3/hour. The land area required for the construction of the 3R TPS on Sabira Island is 193.67 m2. The social feasibility study in the plan for the construction of the 3R TPS on Sabira Island is that the people of Sabira Island support the plan for the construction of the 3R TPS. The service period of 3R TPS according to the technical analysis above is 10 years. Facilities and infrastructure are evaluated according to the applicable SNI standards in the current planning year.
