Tesis ini membahas mengenai penilaian risiko kesehatan berdasarkan task analysis padaaktivitas well services industri pengeboran minyak bumi di PT X Tahun 2019. Penelitianini adalah penelitian semikuantitatif dengan desain deskriptif berdasarkan HRA modelPT Pertamina (2018) berdasarkan factor tingkat pajanan dan tingkat. Langkah awal yangdilakukan adalah dengan mengidentifikasi aktivitas well services berdasarkan task yangada pada SOP dan JSA, walkthrough survey dan menilai risiko. Berdasarkan penilaianrisiko kesehatan didapatkan tingkat risiko tinggi (high) untuk bahaya bising terhadap SEGfloorman, driller, derrickman, dan mechanic dan bahaya ergonomi terhadap SEGfloorman, driller, derrickman, dan operator dozer. PT AB dan PT CD perlu melakukanpengendalian tambahan terhadap bahaya bising dan bahaya ergonomi antara lain:Hearing Loss Prevention Program (HLPP), audit terhadap SOP & peralatan, melakukanpengukuran dosis personal bahaya bising, pembatasan jam kerja, pengukuran audiometri,melakukan supervisi dilapangan terhadap pengunaan earplug, pengunaan double earplug& earmuff, melakukan sosialisasi bahaya bising secara konsisten, menyediakan perancah(scafolding) pada aktivitas nipple up & nipple down horse head, melakukan pelatihanposisi tubuh yang ergonomi serta menambahkan Ergonomic Postur Assessment sebagaisalah satu item dalam pemeriksaan kesehatan berkala. Bahaya gas H2S terhadap SEGfloorman, driller dan derrickman dan bahaya gas CO terhadap SEG mechanicmendapatkan tingkat risiko medium, sehingga perlu dilakukan pemantauan implementasipengendalian yang sudah ada serta pengendalian tambahan secara konsisten. Selanjutnyabahaya getaran mendapatkan tingkat risiko low terhadap SEG mechanic dan bahaya gasO2 terhadap SEG floorman, driller, derrickman, mechanic dan operator Dozermendapatkan tingkat risiko very low, oleh karena itu PT AB dan PT CD melalui HESdepartemen perlu melakukan monitoring secara berkala dan konsisten terhadapimpelementasi pengendalian yang sudah ada. Selain itu hasil penelitian ini jugamenyarankan bahwa identifikasi potensi bahaya lainnya seperti pencahayan, radiasigamma, heat stress, welding fume, bahaya biologi dan bahaya psikososial pada pekerjaanwell services berdasarkan task analysis.

This thesis discusses the health risk assessment based on task analysis on the well services

activities of the petroleum drilling industry at PT X 2019. This research is a

semiquantitative study with a descriptive design based on the HRA model of PT

Pertamina (2018) bases factor exposure level and hazard level. The first step is to identify

performed the task well services based on SOP and JSA, walkthrough survey and risk

assessment. Based on the health risk assessment, there is a high risk level for noise

hazards to similar exposure group (SEG) floorman, driller, derrickman, and mechanic

and ergonomic hazards to floorman, driller, derrickman, and dozer operators. PT AB

and PT CD need to conduct additional controls for noise hazards and ergonomic hazards,

including: Hearing Loss Prevention Program, auditing SOPs & equipment, measuring

personal dose of noise hazards, limiting working hours, audiometric measurements,

conducting field supervision of the use of earplugs, using double earplugs and earmuffs,

disseminating noise hazards consistently, providing scaffolding for Nipple Up and Nipple

Down Horse Head activities, conducting ergonomic body position training, and adding

Ergonomic Posture Assessment as an item in periodic health checks. The hazard of H2S

gas to the SEG floorman, driller and derrickman and the danger of CO gas to the SEG

mechanic has a medium level of risk, it is necessary to monitor the implementation of

existing controls as well as additional controls consistently. Furthermore, the vibration

hazard gets a low risk level for the SEG mechanic and the danger of O2 gas against the

SEG floorman, driller, derrickman, mechanic and Dozer operators get a very low risk

level, therefore PT AB and PT CD through the HES department need to monitor regularly

and consistently the implementation of existing controls. In addition, the results of this

study also suggest that the identification of other potential hazards such as lighting,

gamma radiation, heat stress, welding fume, biological hazards and psychosocial

hazards in well-service work based on task analysis
