Dalam Skripsi ini akan dibahas mengenai analisis tegangan sistem perpipaan di proyek x pada line no 0C27LBA01-14”-AD20 BR001, 0C27LBA01-14”-AA20 BR005 dan 0CSGLBA01-18”-AA20 BR001 yang mana fluida yang mengalir pada pipa mengalami fluktuasi pada pressure dan temperatur setiap harinya dan diperlukan analisis perhitungan tegangannya untuk memastikan jalur pipa yang telah terpasang dan tumpuan pipa yang diletakkan tepat pada tempatnya sehingga tegangan (stress) yang terjadi tidak melebihi limitasi besaran maksimal tegangan yang sudah diatur oleh code/standar ASME B31.1. Hasil analisa perhitungan tegangan akibat beban Sustain maksimum berada pada node 180 pada program CAESAR II sebesar 564,2 Kg/cm² dan perhitungan manual sebesar 327,3 Kg/cm² dengan deviasi perhitungan sebesar 41,99%. Untuk perhitungan tegangan akibat beban Ekspansi maksimum berada pada node 149 pada program CAESAR II sebesar 1079,3 Kg/cm² dan perhitungan manual sebesar 791,98 Kg/cm², dengan deviasi perhitungan sebesar 26,71%. Nilai beban Sustain dan beban Ekspansi dengan dua metode perhitungan tidak ada yang melebihi batas tegangan yang diizinkan code/standar ASME B31.1,dan akibat fluktuasi fluida dari segi pressure dan temperatur yang mengakibatkan pipa mengalami perubahan yang tidak menentu setiap harinya maka pada node 180 perlu dipasang support yang lebih fleksible sehingga dapat mengikuti perubahan pipa tersebut, sehingga dapat disimpulkan bahwa sistem perpipaan di proyek x tidak terjadi overstress dan aman untuk beroperasi.","PeriodicalId":441070,"journal":{"name":"Bina Teknika","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115307875","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}

One type of tool steel that is widely used by the manufacturing industry is SKD steel type 61. ST 41 steel material is a low carbon steel with a carbon content of 0.08% -0.20%. ST 41 steel is commonly used as industrial machine component, but in this ST 41 steel is not as strong as steel SKD 61. So, to improve quality to ST 41 steel. Quality improvement can be done by heat treatment process. To obtain hardness requires the heating process , holding time, cooling medium, precise hardening temperature and see the material comparison between SKD 61 steel and ST 41 steel before and after the hardening process to the nature of hardness and microstructure. Result of hardness test of SKD 61 nonheattreatment steel material has hardness value equal to 197 HV, ST 41 nonheatreatment steel material has hardness value equal to 165 HV, after hardening for temperature 900 ⁰ C has hardness value 154 HV, temperature 950 ⁰ C has hardness value 152 HV, temperature 1000 ⁰ C has 161 HV magnification value.

The problem that occurs from the gas turbine system is decreasing of electrical power. From the commissioning data, GTG 8 is capable of generating 120.2 megawatts of electrical power. In March 2017 GTG 8 was only able to generate electricity by 109.1 megawatts. There was a decrease of 9.23% of electric power capacity. Overview of thermal efficiency and heat loss needs to be done to find out improvement opportunities and recommendations. At commissioning period, thermal efficiency reaches 32.06% while from 2013 to 2017 the average thermal efficiency value reaches only 29.25%. From the data obtained rate of efficiency decreasing 2.81%. At commissioning, the resulting heat loss only reached 135.03 MW. The current operating conditions average heat loss reached 172.50 MW. There was a deviation of 37.47 MW or 21.7%. Based on calculations and data, one factor that can decrease of thermal efficiency and increase heat loss is the compression temperature. The increase in compression temperature is caused by the dust and impurities that enter into the compressor that precipitates on the compressor blades so that the compressed air temperature tends to increase. Dust and impurities can be reduced by the offline water wash method. This process can lower the compression temperature from 693.68 O F to 690.62 O F. A decline of 3.06 O F. This results in actual work of the compressor decreasing from 153.26 Btu / lb to 152.13 Btu / lb. Turbine thermal efficiency tends to increase from 29.02% to 29.43% or increase by 0.41%. After the offline water wash process, the generator generated power reaches 110.50 MW. Increases 4 MW or 3.62% compared to before the compressor is cleaned. The increase causes the system's heat loss to decrease by 5.2 MW or 2.96%.","PeriodicalId":441070,"journal":{"name":"Bina Teknika","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128916391","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}

One of the solutions for securing a motorcycle from theft is by applying intellegent security system technology. The purpose of this research was to design motorcycle security system with fingerprint sensor and determine the percentage of sytem design success. The research methods used are designing, formulating problem and studying literature. The next step are to design the system design and assemble the design. The first was a registered the fingerprint owner motorcycle in order recorded in the data system. The second was to match the fingerprint registered. The design assembly consists of power supply, arduino UNO microcontroller module, fingerprint module, LED and relay module which would be connected with the electrical system motorcycle. Next step was to install the prototype on the motorcycle that connected the relay module with the wire between switch of side buffer and the machine of motorcycle. The result of the triasl system with Thirteen the user motorcycle his fingerprints was not registered indicates system 100% seccess.
