Hasil penelitian didapatkan prevalensi operator yang mengalami fatigue ringan 80,4% dan fatigue sedang sebanyak 19,6%. Variabel lama jam kerja, kondisi fisik/kesehatan, waktu tidur dan shift kerja merupakan variabel yang berhubungan dengan kejadian fatigue pada analisis bivariat sedangkan variabel yang paling berpengaruh pada kejadian fatigue adalah variabel shift kerja dimana shift kerja merupakan satu-satunya variabel yang berhubungan dengan fatigue pada analisis multivariat. Responden yang bekerja shift malam mempunyai peluang 11,046 kali dibandingkan dengan responden yang bekerja shift siang.
Kata kunci : fatigue, shift kerja, kondisi fisik/kesehatan, jam kerja, waktu tidur
Fatigue is the one problem faced by company related to occupational health and safety issues, mainly in company which applies shift work system. The porpuse of the research is to figure out of fatigue prevalence in geothermal power plant operator and risk factors related to fatigue that make its occurence. The design of this study uses cross sectional method, where the datas collect by using questionnarie of international fatigue research committee (IFRC), field observation, operational data and direct measurement. There are many factors which are associated with fatigue. But in this study, there are 11 variables that is taken. They are: age, body mass index, monotonous, working hours, sleep hours, physical/health condition, shift work, work load, lighthing, temperature and noise.
The result of study shows the prevalence of operator that is light fatigue 80,4% and medium fatigue 19,6%. The variable independent which is related to fatigue are working hours, physical/health condition, sleep hours and shift work (the result from analysis bivariate). In multivariate analysis the variable that is significant influencing of fatigue occurence is shift work with the odd ratio 11,04. It means the workers who work on night shift has opportunity to being fatigue 11,045 times compare to workers who work on day shift.
Key Word : fatigue, shift work, working hours, physical/health condition, sleep hours.
Pembangkit lislrik panas bumi berkembang pesat pada saat ini, karena merupakan salah satu sumber energi pengganti selain migas. PT XYZ dalam hal ini juga ikut berperan aktif dalam tahapan engineering, procurement, konstruksi industry energi PLTP ini. Dalam kegiatan konstruksi tersebut PT XYZ mempunyai potensi keuntungan maupun resiko kerugian terhadap kegiatan ini. Pada 5 tahun terakhir ini PT XYZ mengalami kerugian akibat kecelakaan pada tahapan commissioning, meskipun hal ini sudah diasuransikan, antara lain data kecelakaan sebagai berikut : a. Kerusakan Furnish pada saat commissioning di proyek Blue Sky Refenery pada tahun 2005 b. Bocomya Reaklor Urea pada saat commissioning di proyek Kujang I B di tahun 2005. c. Pada proyek PLTP Kamojang- 4 terjadi kerusakan pada separator dan pipe line pada tahapan kegiatan commissioning pada tahnn 2007, Dalarn hal iui resiko perusabaau unruk mendapat potensi kerugian dari kegitan commissioning ini cukup besar, jika dilihat darl pengalaman proyek-proyek sebelumnya tahapan commissioning menyumbang banyak kecelakaan yang menimbulkan potensi kerugian pada peruaahaan, meskipun dalam hal ini proteksi kesehatan dan keselamatan kerja melalui process safety management sudah dilakukan. Oleh karena itu perlu dilakukan evalusi terhadap process safety management yang digunakan sebagai proteksi terhadap hazards/bahaya-bebeya yang ada pada kegiatan commissioning ini. Secara umum tujuan penelitian ini adalah untuk mengetahui seberapa besar tingkat efektivitas proteksi K3 yang dilakukan untuk menoegah kerugian perusahaan pada tahapan kegiatan commissioning pipa sags pada pembangunan PLTP.
Geothermal power energy rapidly grow in this time because as one of energy source substitution besides oil and the reserve gas is progressively attenuate. PT XYZ in this case also contribute is active in industrial construction of this geothermal power energy. In the activity of construction, PT XYZ have loss risk and also advantage potency to this activity. At 5 the last year PT XYZ experience loss of accident effect at step commissioning, though this thing have been insured, for example accident data as follows : 1. Damage of Funish at commissioning in project of Blue Sky Refenery in 2005 th 2. Damage of area Reactor at commissioning in project ujang I B in 2005 th 3. At project of PLTP Kamojang - 4 happened damage at separator and pipe line atstep of commissioning activities in the year 2007th. Therefore require to be done by evaluation to protection system process safety management (K3) which applied as protection to Hazards on the this commissioning activity. In general purpose of research is to how know big level of protection effectiveness process safety management (K3) which done to prevent loss of company at phases of pipe sags commissioning activities at geothermal power energy development.
Based on the literature review, there is a relationship between work distress and safety climate, which affects to work accidents. This study aims to determine the relationship of the dimensions of work distress to the safety climate. A cross-sectional study was conducted on 152 employees of a gas-fired power plant company at the Prabumulih site, Palembang, and two Batam sites, in the operation and maintenance department who were randomly selected as research respondents. Respondents filled out the Nordic safety climate (NOSACQ-50) and NIOSH Generic Job Stress online questionnaire. Data were analyzed using bivariate correlation statistical tests and linear regression. Company's safety climate showed an average result of 2.73 or at a sufficient level, required improvement in the commitment of the workforce to safety and safety priorities. There were 10.53% of employees who have low levels of distress, 77.63% of employees who have moderate levels of distress, and 11.84% of employees who have high levels of distress. Bivariate analysis showed that the variables of work distress on self-assessment, future work, and social support, showed a significant relationship with safety climate. Multivariate analysis showed that the variables of work distress in conflict and role ambiguity were the most dominant variables related to the safety climate. To improve safety climate, Company should strive to reduce workplace distress through controlling conflict factors and role ambiguity.
Karyawan musiman atau kontrak merupakan permasalahan dalam penerapan sistem manajemen di perusahaan. Sifatnya yang dipekerjakan dalam waktu tertentu dan merupakan pekerja kasual merupakan hambatan dalam penerapan SMK3, hal ini dibuktikan dengan kecelakaan kerja yang terjadi di perusahaan. Tesis ini mengembangkan penelitian terhadap investigasi kecelakaan untuk mencari faktor-faktor yang menyebabkan terjadinya kecelakaan pada karyawan musiman atau kontrak. Penelitian dilakukan untuk mencari kesalahan-kesalahan aktif maupun laten sehingga tindakan yang sistemik dapat ditentukan. Penelitian ini bersifat deskriptif analitik dengan. Hasil penelitian ini menyarankan tindakan perbaikan pada elemen-elemen sistem manajemen keselamatan dan kesehatan kerja untuk mengurangi atau menghilangkan kesalahan-kesalahan baik aktif maupun laten sehingga akan memperkuat ketahanan sistem terhadap terjadinya kecelakaan.
Temporary or contract worker has an issue on implementing safety management system in the company. The type of their employment with short term/temporary basis and as casual worker become a burdain on implementing safety management system, this shown on the safety accident that happened in the company. This Thesis developed a research on the incident investigation to find the factors of accident that caused an injury to the temporary or contract worker. The research is to identify active and latent failure, so the systemic improvement action plans could be developed. The research type is in depth analysis with descriptive qualitative as a result. The result of the research propose improvement on the safety management system elements to minimize or eliminate active or latent failure and so, develop strong defense to accident to.
Hasil penelitian menunjukkan pekerja yang terpajan kebisingan >80 dBA memiliki tekanan darah dan prevalensi hipertensi yang lebih tinggi dibandingkan pekerja yang terpajan kebisingan ≤80 dBA. Pekerja yang terpajan kebisingan >80 dBA memiliki tingkat risiko terkena hipertensi lebih tinggi dengan OR = 3,19 dibandingkan dengan pekerja yang terpajan kebisingan ≤80 dBA. Tidak ada hubungan antara intensitas kebisingan dengan tekanan darah dan hipertensi. Akan tetapi terdapat kecenderungan dosis-respon antara intensitas kebisingan dengan tekanan darah sistolik, tekanan darah diastolik dan hipertensi
