"Latar Belakang: Asam tioglikolat (TGA) yang digunakan sebagai bahan baku corrosion inhibitor dapat menghasilkan H2S (hidrogen sulfida) dan memajan kesehatan pekerja. Tujuan penelitian adalah menganalisis tingkat risiko H2S dari TGA dalam produk CI beserta usulan pengendalian risiko di perusahaan. Metodologi: Chemical Health Risk Assessment (CHRA) menurut DOSH versi 2018 pada dua unit kerja terpajan di PT. X, yaitu Unit kerja 1 (area produksi) dan Unit Kerja 2 (area warehouse). Hasil: Sesuai DOSH, tingkat risiko kesehatan gas H2S termasuk hazard rating (HR) = 5. Analisis exposure rating (ER) secara kualitatif menunjukkan ER area produksi (4) lebih tinggi dari ER di area warehouse (3) karena perbedaan frequency-duration rating (FDR) antar unit kerja. Dengan menghubungkan Magnitude rating (MR) saat aktivitas membuka tutup drum CI = 4, tingkat risiko kesehatan berada pada high risk level (RR = 20 Unit Kerja 1; RR = 15 Unit Kerja 2). Kesimpulan: Risiko kesehatan akibat pajanan H2S dari CI termasuk pada high risk level menurut CHRA DOSH dan langkah utama yang perlu dilakukan adalah subsitusi untuk menurunkan level risiko. Kesesuaian langkah pengendalian teknis, administratif, dan APD sangat penting saat TGA digunakan dalam produk corrosion inhibitor.

Background: Thioglycolic acid (TGA) is used as iron ion reduction in corrosion inhibitor which can produce H2S (hydrogen sulfide) and expose to human health. The purpose of this research is to analyze the risk level of H2S exposure from CI along with the proposed risk control in the company. Methodology: Chemical Health Risk Assessment (CHRA) according to DOSH (2018) in two exposed work units in PT. X (Work Unit 1 as production area and Work Unit 2 as warehouse area). Result: According to DOSH, the hazard rating of H2S is 5. Qualitative exposure rating (ER) analysis shows the ER of the production area (4) is higher than ER in the warehouse area (3) due to the difference in frequency-duration rating (FDR). By considering the Magnitude rating (MR) during drums opening is 4, the level of health risk is at high risk level (RR Work Units 1 = 20; RR Work Units 2 = 15). Conclusion: H2S exposure from CI is at high risk level according to CHRA DOSH and the main required control is substitution to reduce the risk level. Adequacy of technical, administrative, and PPE control measures is critical when TGA is used in corrosion inhibitor."

Gas – Oil Separator merupakan salah satu peralatan utama dalam Fasilitas Pemrosesan Gas Bumi. Gas – Oil Separator merupakan suatu bejana tekan yang berfungsi untuk memisahkan fluida dari sumur migas menjadi fasa gas dan fasa cair. Peralatan ini dipasang pada Fasilitas Pemrosesan Gas Bumi sebagai peralatan pertama yang dilalui oleh fluida produksi yang mengalir dari sumur migas dan jaringan pipa pengumpul. Separator akan memisahkan fluida produksi tersebut menjadi gas, kondensat, dan air. Dengan demikian, cairan dan gas akan memenuhi ruang separator. Volume cairan dan tekanan gas harus dapat dikendalikan untuk menjamin process safety. Untuk mencegah terjadinya risiko keselamatan, komponen instrumentasi keselamatan dibutuhkan untuk dapat mengendalikan fluida di dalam sistem, sehingga risiko tersebut dapat dicegah. Dalam hal ini, salah satunya diperlukan pemilihan desain dan ukuran yang sesuai dari sebuah liquid control valve untuk menjamin process safety. Liquid control valve digunakan untuk mengendalikan ketinggian cairan di dalam separator untuk mencegah fluida dapat mencapai batas ketinggian maksimum maupun minimum cairan di separator. Untuk menghasilkan sebuah liquid control valve yang handal, diperlukan perhitungan sizing dan pemilihan tipe desain yang sesuai dengan kondisi operasional yang diinginkan. Penelitian ini menghasilkan perhitungan sizing dan pemilihan desain yang harus dipenuhi untuk mendapatkan sebuah liquid control valve yang tepat dan handal untuk dipasang pada Sistem Gas – Oil Separator."

"ABSTRAKANRI-Indoflesia Company has been facing a problem in selling natural gas to domesticindustry due to the Indonesia monetary crisis. ANRI has discovered big gas in severalcontract areas in Indonesia under Pertamina concession. In addition, ANRI mission isbecoming leadership in gas producer in next years. Therefore, a management strategy hasto be formulated in order to achieve a sustainable competitive advantage and earningsabove average during the Asia economic turmoil condition. Many customers have bought gas in US dollar contracts to ANRI but currency fluctuationhas hurt the customers earning. Furthermore, low purchasing power of people hasdrastically decreased during crisis. Some firms therefore, such as PLN, have delayed inpayment to ANRI. ANRI has worldwide reputation in upstream and downstream business, especially inIndonesia that ANRI has only focussed in upstream business. Meanwhile, economic gasreserve has been discovered in Irian Jaya, Bali and Java. In addition the ANRI has beenfacing uncertainties gas market in both domestic and overseas during the crisis. ThereforeANRI-Indonesia is interested for research study. The research method of the thesis will use two types of research sources: 1. Primary data Data were collected by survey using a questionnaire form for human resource,SPACE matrix, Internal-External matrix and QSPM. 2. Secondary data Data were gathered using internal and external data. The data, consists of general environment, industry environment, competitiveenvironment and internal analysis, is formulated with applying SWOT, SPACE, GrandStrategy and Internal External Matrices. Finally, recommendation for the ANRI strategicmanagement during crisis is divided into three, short-term, medium-term and long term.Short-term strategic management is prioritized on Market Penetration, MarketDevelopment, Backward Integration, Retrenchment, 1-lorizontal Integration andSuspended gas development. Medium-term strategic management is focused on vertical chain alliances in downstreambusiness, Divestiture, Liquidation and Forward Integration. Long-term strategic management is established on searching new fields.A research weakness of the thesis is not provided equivalence number of energy demandin domestic and overseas. Therefore gas demand in market will not exactly be knownhow much of domestic and overseas need. Future studies are suggested to research how much gas demand in domestic and overseasmarket. Then gas development can be accurately predicted in future, in addition gas pricecan be negotiated in right profit for sustainable of the business."
