Kebisingan yang dikeluarkan mesin TFO sangat menganggu operator dalam melaksanakan tugasnya sehingga memicu terjadinya stres kerja. Sehingga p erlu dilakukan pengukuran mengenai kebisingan di mesin TFO dengan Enviro meter kemudian dilakukan uji korelasi Spearmen dengan software SPSS 16  untuk mengetahui hubungan kebisingan dengan stres kerja operator mesin TFO. Hasil uji korelasi spearmen menunjukkan bahwa adanya hubungan yang kuat antara kebisingan dengan stres kerja (p value = 0,042). Kemudian dilakukan upaya untuk mengurangi tingkat kebisingan sehingga akan menggurangi stres kerja bagi para pekerja. Dengan menggunakan analisis Fault Tree Analysis sumber kebisingan untuk mengetahui sumber kebisingan. Berdasarkan analisis kualitatif FTA sumber kebisingan, penyebab kebisingan : lupa memberi minyak pelumas, seal katup oli bocor, bearing tidak diganti (masa ekonomis 2 tahun),traveller tidak diganti (masa ekonomis 10 hari), dan mesin Doubling bermasalah. Berdasarkan analisis kuantitatif probabilitas munculnya stres kerja operator mesin TFO akibat kebisingan mesin TFO dari probabilitas yang diketahui 0,041. Angka ini menunjukkan sistem tersebut dalam keadaan layak digunakan. Abstract [Analysis of Noise Relationship with Work Stress on Operator Machine Part Two For One Twister (TFO) XYZ]. Issued noise is very disturbing operators TFO machine in performing their duties causing job stress. So it is necessary to measure the noise in the engine TFO with Enviro-meter then do Spearman correlation test performed with SPSS 16 software to determine the relationship of noise with work stress TFO machine operator. Spearmen correlation test results showed that a strong correlation between noise with work stress (p value = 0.042). Then efforts to reduce the noise level that will decrease stress for workers. By using Fault Tree Analysis to determine the source of the noise. Based on qualitative analysis of FTA sources of noise, the cause of the noise: forgot to give the lubricating oil,seal valve oil leak, bearing not replaced (economic life of 2 years), the traveler is not replaced (economic life of 10 days), and the machine Doubling problematic. Based on the quantitative analysis of the probability of job stress of TFO machine operator due to noise TFO machines from a known probability of 0.041. This figure shows the system is in a state fit for use.","PeriodicalId":380157,"journal":{"name":"Industrial Engineering Online Journal","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133305885","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}

Ketidakpuasan penumpang tersebut berdampak pada rendahnya angka load factor yang secara tidak langsung juga berdampak pada kondisi finansial BRT Trans Semarang. Pada penelitian ini disusun beberapa skenario kebijakan pengembangan BRT Trans Semarang dengan menggunakan pendekatan sistem dinamis untuk mengetahui fitur-fitur apa saja yang harus dikembangkan agar memberi keuntungan tidak hanya dari segi finansial tapi juga non finansial antara lain skenario pengadaan feeder, skenario penambahan armada dan skenario pengadaan feeder dan penambahan armada. Berdasarkan hasil penelitian didapatkan kebijakan terbaik adalah dengan pengadaan feeder. Dengan kebijakan ini, load factor dapat mencapai target ≥ 70% pada bulan ke-15, tidak perlu ada subsidi dari pemerintah serta presentase perpindahan pengguna kendaraan pribadi mencapai 26%. ABSTRACT Bus Rapid Transit (BRT) Trans Semarang which was originally intended to anticipate the occurrence of congestion in Semarang city experienced a lot of problems such as passenger complaints about long waiting times buses, bus facilities and shelter, as well as the driving issue. The passenger dissatisfaction adversely affects the load factor rate, which indirectly also affects on the financial condition of BRT Trans Semarang. In this study developed several scenarios Trans Semarang BRT development policies using a dynamic systems approach to determine what features should be developed in order to provide benefits not only in financial terms but also non financial such as  a supply feeder scenario, a addition fleet scenario, and a supply feeder and addition fleet scenario. Based on the results, the best policy is to supply feeder. With this policy, load factor can reach the target of ≥ 70% at month 15, there should be no subsidy from the government as well as private vehicle user switching percentage reached 26%.","PeriodicalId":380157,"journal":{"name":"Industrial Engineering Online Journal","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115366372","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}
