Abstract

In today's society infrastructure development , especially in the field of housing and there's also a supporting infrastructure utilization and the use of paving blocks as a construction material . This is because the use of paving blocks are generally considered less expensive and easy execution. Blangket soil can be categorized as one of the kinds of soils containing lime , which is the precipitate formed by chemical processes or mechanisms in nature ( BKPM Technology of Materials 2 ; 2002) . Blangket soil has physical characteristics such as clay or loose, white or dull yellow. This soil is found in the area Grobogan . This study tried to assess the use of the material as a mixture of blangket soil making paving blocks in terms of compressive strength. This study used an experimental method in the laboratory testing of materials POLINES Civil Engineering department, where for each of the mixtures made 3 test object. The test results indicate that the material can be used as an alternative blangket soil as a mixture of block paving to reduce and replace the use of sand material . It is shown from the results of testing compressive strength of paving blocks with a mixture of soil blangket in comparison 1PC : 4Ps : 2TB has a compressive strength of 10.75 MPa , which qualified quality block paving D ( SNI 03-0691-1996 use for a garden ). For future development needs to be done further research on the use of land blangket as material for paving blocks in terms of economics.

Abstract

Test selection is very influential in determining the design parameters. The aim of this research is to study the dimensions of the triaxial test soil sample on clay soils in the Semarang area to obtain soil shear parameters that can be used as design parameters. The tests include testing the physical and mechanical properties of the soil. Mechanical testing uses a triaxial test. The UU triaxial test sample is modeled with a diameter of 3.5 cm and 3.8 cm, while the CU sample is 3.5 cm. Based on the results of soil property index testing, sieve analysis, and consistency limits, it can be concluded that the soil samples are non-organic clay with high plasticity. Based on the triaxial test UU values of c and Ï… it can be seen that the largest shear parameter occurs in the specimen with a diameter of 3.8 cm. The largest UU triaxial test c value is 0.32 kg/cm2 , meanwhile, for Ï… it has a value of 11.65 º. The specimen with a larger diameter has a greater shear stress value. This can be influenced by larger c and Ï… values. The c and c' values of the triaxial CU test results were 0.32 kg/cm2 and 0.50 kg/cm2 respectively. While the values of Ï… and Ï…' are 9.89 º and 17.35 º respectively. The Ï„ and Ï„' values obtained were 1,394 kg/cm2 and 1,405 kg/cm2 , respectively. The modulus of elasticity of soil is 1500 kN/m2 and 3200 kN/m2 respectively which is included in the type of soft clay soil with a value range of 1800 ”“ 3500 kN/m2 and is included in the CH classification with a range of 0.35”“4 MPa. The value of the elastic modulus taking into account the value of cohesion, plasticity index, and OCR is closer to the prediction of soil elastic modulus values by Das

Abstract

Pengabdian masyarakat yang berupa pendampingan pembangunan kostruksi jembatan beton bertulang sebagai akses menuju Musholla Al Barokah di wilayah RT 03 RW VII kelurahan Nyatnyono, Ungaran Barat Kabupaten Semarang. Masa Pelaksanaan selama 6(enam) bulan, daribulan Oktober 2021. Pendampingan dirasakan sangat perlu, dikarenakan pembangunanya berupa kontruksi jembatan beton bertulang, yang menghubungan dua elevasi yang berbeda. Perbedaan elevasi yang mencapai 6,5 meter dan dengan panjang jembatan hampir 35 meter serta lebar jembatan 1,5 meter. Kontribusi mitra berupa beberapa material seperti batu kali, batu bata, pasir maupun beberapa tenaga kerja. Permasalahan utama adalah tidak adanya tenaga pelaksana bangunan khususnya didalam membangun Jembatan beton bertulang baik dari sisi biaya pelaksanaan maupun supervisi. Adapun solusi yang ditawarkan berupa pendampingan didalammengkalkulasi biaya pelaksanaan maupun supervisi dalam pembangunan. Kontribusi mendasar daripengabdian adalah mendapatkan pengetahuan dan pengalaman dalam mengkalkulasi kebutuhan biaya, pelaksanaan serta supervisi dalam membangun Jembatan. Luaran berupa hasil pendampingan didalammelaksanakan pembangunan Jembatan di Wilayah Nyatnyono, Ungaran Barat, Kabupaten Semarang.

Abstract

The plumbing system must be able to anticipate pollution from outside, So damage to pipes must be minimized because if there is a leak in the pipe it will not only affect water distribution but can also cause the water to be contaminated with dirt. Research needs to be carried out regarding inspection methods and techniques for repairing leaks in pipe installations so that if the installation experiences a leak it can be repaired immediately. The method used in this research is an experimental method, namely modeling a water pipe installation that has a leak, then applying inspection techniques and repair techniques to the pipe installation. Based on water discharge measurements carried out during 1 minute of water flow in pipe installations in normal conditions with pipes experiencing leaks, there was a decrease in water discharge of 39.023 liters/minute. To find out the leak point, it is necessary to carry out a further inspection using a pipe leak listening device. The results of the inspection carried out three times with different people showed that the inspection results shifted from the leak point by a maximum of 10 mm. Based on the research results, it was found that a repair technique that can be applied to leaks in galvanized pipe installations is strengthening with pipe clamps capable of withstanding a pressure of 1.2 Mpa with an implementation cost of Rp. 277,500.00, and the welded reinforcement is able to withstand a pressure of 3.4 Mpa with an implementation cost of Rp. 463,458.00. So the inspection method of measuring flow and checking with a listening device can be applied to check leak points in pipe installations, while the most appropriate method for repairing leaks in galvanized pipe installations is to use pipe clamp reinforcement, because it obtains a compressive strength that meets the minimum pressure requirements in pipe installations. residential house and in terms of costs it is cheaper than using welding reinforcement techniques.

Abstract

Damage to the roof frame construction can have an impact on other components, for example if the roof frame sags resulting in the roof covering becoming loose resulting in a leak, the leak can impact the ceiling, causing moldy damage to the worst case, collapsing. So it is necessary to ensure that the roof frame construction is always in a reliable condition, so that it does not endanger the building occupants. The method used in this research is a case study method, a model of the damaged steel roof frame construction will be made, Then a visual inspection will be carried out until further inspection. Based on the results of a visual inspection of the truss frame construction, it was found that there was a deflection in the lower frame of 4mm, there was rust which reduced the thickness of the elbow profile by 0.51mm, and the loss of some of the bolt connections was 20bh. The results of the inspection were then carried out with a strength analysis, it was found that based on the deflection results it was still below 9.33 mm, it was still safe, based on rust damage, a strength reduction of 13.31% was obtained, while based on the loss of some of the bolted connections, a strength reduction of 23.81% was obtained. Then a direct loading test was carried out on the construction of the truss frame after it had been conditioned to experience damage, capable of withstanding a maximum point load of 249 kg, where the test results experienced a decrease in strength from the plan and were still greater than the inspection results. So it can be concluded that the method for checking the construction condition of steel truss frames for deflection, rust conditions and joints can be used as a guide because the results are close to the actual conditions. The intensity of damage that occurred in the truss frame construction was categorized as light damage, because the decrease in strength that occurred was 23.81% smaller than 35%.
