The purpose of this study was to analyze the physical and mechanical properties of clay soil and to analyze value of bearing capacity soil and value of settlement consolidation of the clay after grouting. Soil improvement method in this study is grouting using portland cement and activated lime. Variations will be used are 2 points grouting combination of cement and lime (d = 1 cm) and 4 points grouting combination of cement and lime (d = 0,75 cm). Point diameters are made different so that the total surface area of the sample is same. All samples will be cured for 3 days. The results of physical test, based on AASHTO classification, the soil is in group A-7-6 (6) (clay soil) with moderate to bad condition and USCS system soil is in the CL group. The results of clay soil consolidation test without grouting, Sc = 0,243 cm. Variation 2 points combined grouting, Sc = 0,174 cm and variation 4 points combined grouting, Sc = 0,159 cm. Value bearing capacity of clay without grouting (q ult ) = 4,9053 kg/cm 2 . Variation 2 points combined grouting, the value of bearing capacity (q ult ) = 7,8070 kg/cm 2 and variations 4 points combined grouting, value of bearing capacity (q ult ) = 12,9126 kg/cm 2 . From the test results, it can be concluded that grouting increases the value of the bearing capacity and reduces the value settlement of clay soil.","PeriodicalId":403329,"journal":{"name":"Jurnal Deformasi","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122515367","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Temperature resistance (heat) is one that affects the quality of bricks. One way to increase the heat resistance (temperature) of adobe bricks is to add a mixture of its manufacture, one of which is rice husk. Rice husk has the potential to increase heat resistance because it contains silica. Rice husk waste is mostly obtained from agriculture in the community, but the use of rice husk waste in bricks is still very less.. This study aims to analyze the temperature damping on adobe bricks with a mixture of rice husks. The method used is an experimental approach that begins with a survey of rice husk waste locations and sampling of rice husks at the Pegayut rice mill. The next stage was carried out experimentally in the laboratory. The bricks used were mixed with rice husk variations of 0.1, 0.2 and 0.3 of the composition used for cement. Research has been carried out to determine the attenuation of heat in bricks by placing a heating device on one side of the bricks and then measuring the temperature and on the other side after varying the time from 0 minutes to 15 minutes with with a time span of 5 minutes each. The results of the study showed that the greatest temperature attenuation was in bricks with a mixture of 30% rice husk at 5 minutes the damping time was 75.025 o C, 10 minutes at 79.282 o C and 15 minutes at 82.275 o C. Based on the factorial analysis, the 30% rice husk mixture is the brick with the best temperature damping..","PeriodicalId":403329,"journal":{"name":"Jurnal Deformasi","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125364659","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Planning an irrigation system, the first thing that needs to be done is a hydrological analysis using the Modified Penman method including the water demand in the fields (GFR), the demand for water intake (DR), the clean water requirement in the fields (NFR) as well as the water availability factor which is calculated using FJ Mock method. The hydrological analysis of water demand in the Sumberejo irrigation area aims to determine whether the availability of water is sufficient to irrigate the Sumberejo irrigation area which covers an area of 42.37 Ha. The results of the calculation analysis, it is known that the water requirement for an area of 42.37 Ha, the water discharge in the 1st planting season is 0.16 m3/s, while the water requirement is 0.04 m3/s. the existing water discharge in the 2nd planting season is 0.05 m3/s, while the water requirement is 0.06 m3/s. The determination of the rice-paddy cropping pattern for the first planting season begins in April I and the second planting season begins in August II. Based on the results of the calculation of water needs in the second planting season has not been met.","PeriodicalId":403329,"journal":{"name":"Jurnal Deformasi","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131657307","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
