"Kejadian kecelakaan di Stasiun Pengisian Bahan Bakar Umum (SPBU) merupakan kejadian yang mendominasi kecelakaan jika dilihat berdasarkan jenis kegiatan usaha niaga migas. Seiring terus naiknya statistik kecelakaan, pada tahun 2018 diterbitkan Pedoman Teknis Keselamatan SPBU. Namun setelahnya masih terjadi juga beberapa kecelakaan yang didominasi oleh faktor eksternal, sehingga perlu ada solusi untuk menekan angka kecelakaan SPBU tersebut yang sekiranya belum tertulis di Pedoman tersebut yakni tentang Penerapan Vapor Recovery Unit (VRU) pada SPBU. Berdasarkan permasalahan tersebut maka tujuan penelitian adalah untuk mengkaji dampak pemasangan VRU di SPBU, sehingga dapat memberikan masukan rekomendasi pada revisi pedoman termaksud. Penelitian yang dilakukan dengan Forum Group Discussion (FGD) dengan para pelaku usaha bidang migas dan hasil penelitian menunjukkan bahwa pemasangan VRU memberikan keuntungan secara ekonomi dengan syarat jika dipasang dalam kapasitas penyaluran besar. Pemasangan VRU telah digambarkan dalam pemasangan di Terminal yang menyajikan data keuntungan secara kuantitatif meliputi keuntungan materi, safety, kesehatan, dan lingkungan. Meskipun pemasangan VRU di SPBU dengan kapasitas penyaluran kecil maka dipastikan kurang memberikan keuntungan materi, bahkan terjadinya cost waste, namun kontribusi terhadap safety, kesehatan, dan lingkungan layak diperhitungkan. Rekomendasi untuk memasukkan kewajiban penerapan VRU pada Pedoman Keselamatan SPBU perlu ditambahkan namun dengan batasan kapasitas penyaluran dan beberapa hal tentang pemeliharaan.

Accidents at Gas Stations (SPBU) are events that dominate accidents when viewed based on the type of oil and gas trading business activities. As accident statistics continue to rise, in 2018 the Gas Station Safety Technical Guidelines were published. However, after that, there were still several accidents that were dominated by external factors, so there needed to be a solution to reduce the number of gas station accidents that had not been written in the Guidelines, namely the application of Vapor Recovery Units (VRU) at gas stations. Based on these problems, the purpose of the study was to examine the impact of installing VRUs at gas stations, so that they could provide recommendations for the revision of the guidelines. The research was conducted through a Forum Group Discussion (FGD) with oil and gas business actors and the results showed that the installation of a VRU provides economic benefits provided that it is installed in a large distribution capacity. The VRU installation has been described in the installation at the Terminal which provides quantitative profit data covering material, safety, health, and environmental benefits. Although the installation of a VRU at a gas station with a small distribution capacity will certainly not provide material benefits, even the occurrence of cost waste, but the contribution to safety, health, and the environment deserves to be taken into account. Recommendations to include the mandatory application of VRU in the Gas Station Safety Guidelines need to be added but with limitations on distribution capacity and a few things about maintenance."

"Sejak penggunaan benzena, ditemukan juga dampak kesehatan akibat pemajanan dengan bahan kimia ini. Petugas operator pada pengisian BBM adalah salah satu populasi pekerja yang memiliki tingkat resiko pajanan benzena yang tinggi, terutama melalui jalur inhalasi dalam waktu pajanan yang kontinyu. Metode yang digunakan adalah analisis risiko kesehatan lingkungan, yaitu menghitung besar risiko individu dan populasi. Pada estimasi risiko individu, seluruh karyawan belum berisiko efek nonkarsinogenik, tetapi pada pajanan 3 tahun terdapat 1 karyawan yang berisiko efek kanker dan pada pajanan lifetime seluruh karyawan berisiko efek kanker. Seluruh populasi karyawan belum berisiko efek nonkarsinogenik pada semua durasi pajanan. Populasi operator pompa BBM berisiko efek karsinogenik pada durasi pajanan lifetime. Populasi karyawan bagian administrasi belum berisiko efek karsinogenik pada semua durasi pajanan. Disarankan bekerja tidak lebih dari 3 tahun, bekerja selama maksimal 6 jam/hari atau penggunaan APD yang tepat agar terlindung dari risiko kanker.

Since the use of benzene, was also found health effects due to exposure to these chemicals. Operators in charge of fuel is one of the working population who have high levels of benzene exposure is high risk, mainly through the inhalation pathway of exposure is continuous in time. The method used is the analysis of environmental health risks, namely large calculating individual and population risk. In the individual risk estimates, the employee has not at risk noncarsinogenic effect, but at 3 years of exposure there is an employee at risk of cancer and the effects on lifetime exposure to all employees at risk of cancer effects. The entire population of non-employee has not at risk of carcinogenic effects in all the duration of exposure. The population at risk of fuel pump operators carcinogenic effect on the duration of lifetime exposure. Populations at risk yet the administrative staff of a carcinogenic effect on all the duration of exposure.

"Program untuk memanfaatkan ulang gas flare di Indonesia menjadi salah satu program konserasi energi yang utama sejak keikutsertaan Indonesia dalam kemitraan GGFR (Global Gas Flaring Reduction) dan program The Zero Routine Flaring pada tahun 2030. Dua peraturan sudah dikeluarkan oleh Pemerintah lewat Kementerian Energi dan Sumber Daya Mineral yang menekankan pada aktivitas pengurangan flaring dalam industri migas. Dengan pemanfaatan ulang gas flare menjadi utilitas bahan bakar gas akan mengurangi kerugian kilang dan juga meningkatkan kinerja dan efisiensi pabrik. Penelitian ini mengambil kasus pada kilang di Indonesia yang difokuskan pada: menentukan kapasitas desain FGRS, teknologi sistem recovery gas flare yang akan digunakan, kelayakan ekonomi, keuntungan lingkungan dan analisis dampak terhadap sistem yang ada. Metodologi untuk menentukan desain basis disajikan setelah menganalisis berbagai komposisi dan laju aliran massa gas flare yang datanya diambil harian dalam dua tahun terakhir. Dari berbagai perbandingan kasus, dipilih FGRS dengan kapasitas desain 1,200 Nm3/h yang menggunakan kompresor liquid ring tunggal di mana akan memberikan persentase recovery rate sebesar 28%. Desain ini akan memberikan hasil yang layak secara ekonomis dengan pengembalian tahunan $1.433.572 dan dengan payback period tahun. Konservasi energi ini akan mengurangi emisi sebesar 20.885 Ton CO2 setelah pemasangan FGRS pada sistem flare yang ada di kilang. Tidak ditemukan dampak yang merugikan dari hasil analisis adanya pemasangan unit FGRS terhadap unit sistem flare yang beroperasi sekarang, sehingga rencana investasi proyek ini layak dilaksanakan.

The program to recover gas flares in Indonesia has become one of the main energy conservation programs since Indonesia's participation in the GGFR (Global Gas Flaring Reduction) partnership and The Zero Routine Flaring program in year 2030. Two regulations have been issued by the Government through the Ministry of Energy and Mineral Resources that emphasize flaring reduction activities in the oil and gas industry. By recovering gas flare to become a gas fuel utility, it will reduce refinery losses and also improve plant performance and efficiency. This study takes the case of refinery in Indonesia which is focused on: determining the design capacity of the FGRS, the gas flare recovery system technology to be used, economic feasibility, environmental benefits and impact analysis on the existing system. The methodology for determining the base design is presented after analyzing various compositions and mass flow rates of flare gases whose data are taken daily in the last two years. From various comparison cases, FGRS was chosen with a design capacity of 1,200 Nm3/h which uses a single liquid ring compressor which will provide a percentage recovery rate of 28%. This design will provide economically viable returns with an annual return of $1.433.572, and with a payback period of 6 years. This energy conservation will reduce emissions by 20.885 Tons of CO2 after the installation of FGRS on the flare system at the refinery. No adverse impact was found from the analysis results of the installation of the FGRS unit on the flare system unit currently operating, so that the investment plan for this project is feasible."

"Peningkatan produksi minyak bumi di Indonesia menjadi hal mendesak mengingat target produksi 1 juta barrel perhari pada tahun 2030 di tengah penurunan produksi. Permasalahan tersebut memberikan insentif untuk menelusuri metode EOR non-konvensional, biopolymer flooding. Xanthan Gum merupakan biopolimer dengan ketahanan salting effect yang sangat baik sehingga memberikan potensi digunakan bersama air laut sebagai campuran driving fluid dalam metode injeksi kontinuous. Selain itu, HCPV injeksi meningkatkan performa pemulihan jika flooding berhasil . Maka dari itu, penelitian ini menganalisis pengaruh penggunaan air laut sebagai fluida pendorong dan HCPV injeksi terhadap displacement sweep efficiency, recovery factor, serta harga minyak dan gas untuk IRR 15% mengikuti skema bisnis gross split. Penelitian dengan permodelan reservoir sintetik sandstone heterogen, dilanjutkan dengan permodelan EOR dengan membandingkan berbagai strategi injeksi EOR biopolymer flooding terhadap waterflooding, dan analisis ekonomi cashflow mengikuti skema bisnis gross split. Peningkatan HCPV injeksi dapat meningkatkan recovery factor hingga 22.26% dan displacement sweep efficiency 21.27%. Penggunaaan air laut sebagai campuran fluida pendorong mengurangi recovery factor hingga 0.55% dan displacement sweep efficiency 0.54%. Harga minyak minimum proyek dapat mencapai 45.75$ per barrel dengan cost of EOR sebesar 4.52$ per barrel. 

Increasing Indonesian oil production is an urgent issue due fulfilling Indonesian production target of one million barrels per day in 2030 amidst production decline. This problem gives an incentive to explore non-conventional EOR method, biopolymer flooding. Xanthan gum biopolymer is resistant toward salting effect which has the potential to be used alongside brine as driving fluid mixture in a continuous injection. Moreover, HCPV injection increases oil field’s recovery rate only if the flooding succeeds. Therefore, this research’s purpose is to analyze the usage of brine as driving fluid and HCPV Injection toward partially depleted sandstone reservoir’s displacement sweep efficiency, recovery factor and oil and gas price in reaching IRR 15% following Indonesian gross split scheme. Research methodology includes modelling of synthetic partially depleted heterogenous sandstone reservoir, continued with EOR modelling comparing different biopolymer flooding injection strategy with waterflooding, and cashflow economic analysis following gross split scheme. The increase of HCPV injection could increase recovery factor up to 22.26% dan displacement sweep efficiency up to 21.27%. The usage of sea water as mixture in driving fluid could decrease recovery factor up to 0.55% and displacement sweep efficiency 0.54%. The minimum project oil price reaches 45.75$ per barrel with the cost of EOR 4.52$ per barrel."

"ABSTRAK
Studi Analisis Biaya Pengisian LPG pada Stasiun Pengisian LPG dilakukan untuk mengetahui biaya pengisian LPG 3 kg yang layak / wajar diterima oleh SPPBE / SPBE. Hal ini dikarenakan sejak dilaksanakannya program konversi minyak tanah ke LPG tahun 2007, besaran biaya pengisian LPG yang ditetapkan oleh Pertamina belum pernah mengalami perubahan yaitu sebesar Rp. 300 / Kg. Penelitian ini merinci CAPEX dan OPEX SPPBE existing PT X sebagai dasar melakukan perhitungan analisis keekonomian hingga didapatkan IRR sebesar 11,09 % dan NPV sebesar Rp 487.289.285. Dengan mengasumsikan WACC sama dengan MARR maka WACC = MARR = 17,34% dan selisih MARR dan IRR yang layak sebesar 4% didapatkan nilai IRR yang layak sebesar 21,34% dan NPV sebesar Rp. 9.431.120.721. Dengan IRR yang layak tersebut diperoleh biaya pengisian LPG yang layak / wajar sebesar Rp. 426 / Kg, apabila dibandingkan dengan biaya pengisian LPG yang ditetapkan oleh Pertamina sejak tahun 2007 hingga saat ini yaitu Rp. 300 / Kg, biaya pengisian LPG perlu dinaikkan Rp. 126 / Kg yaitu naik 42 %. Hasil analisis sensitivitas menggunakan random number generator based on monte carlo calculation bahwa perubahan kapasitas pengisian LPG berpengaruh lebih besar dari pada perubahan biaya pengisian LPG terhadap IRR yaitu sebesar 52,1% dan perubahan kapasitas pengisian LPG berpengaruh lebih besar dari pada perubahan biaya pengisian LPG terhadap NPV yaitu sebesar 52,1%. Hasil penelitian ini diharapkan dapat menjadi rekomendasi bagi Pertamina dalam penetapan biaya pengisian LPG Tabung 3 Kg dan masukan bagi Pemerintah dalam menetapkan regulasi terkait pengaturan penetapan biaya pengisian LPG

ABSTRACT
The study The Analysis of LPG Filling Fee at LPG Filling Station is conducted to find out the Filling Fee of 3 kg LPG that is acceptable by SPPBE/SPBE. This is because since the implementation of the conversion program from kerosene to LPG in 2007, the amount of LPG filling fee set by Pertamina has never changed from Rp. 300 / Kg. This study will give details of CAPEX and OPEX of SPPBE/SPBE owned by PT X as the basis of calculating the economic analyses to obtain the IRR as much as 11,09 % and the NPV as much as Rp 487.289.285. Assuming WACC is equal to MARR so WACC = MARR = 17,34 % and the difference between MARR and acceptable IRR is 4 %, it is obtained the acceptable IRR as much as 21,34 % and the NPV as much as Rp. 9.431.120.721. With the acceptable IRR, it is obtained acceptable LPG filling fee as much as Rp. 426 / Kg, when compared to the LPG filling fee set by Pertamina since 2007 until today which is Rp. 300 / Kg, LPG filling fee needs to be raised by Rp. 126 / Kg which is 42 %. The results of a sensitivity analysis using random number generator based on monte carlo calculation show that the effect of changing the capacity of LPG filling is greater than the effect of changing the LPG filling fee on IRR, which is equal to 52.1% and the effect of changing the LPG filling capacity is greater than the effect of changing the LPG filling fee on NPV which is equal to 52, 1%. The results of this study are expected to be the recommendation for Pertamina in determining the Filling Fee of 3 kg LPG and suggestion for the Government in establishing the regulations related to setting up LPG filling fee."

Tujuan dari penelitian ini adalah mengetahui jumlah vapor yang bisa dipulihkan oleh Vapor Recovery Unit (VRU), mengetahui % konsentrasi LEL vapor bahan bakar serta CO, H2S yang terdeteksi di lingkungan SPBU, dan mengetahui kelayakan ekonomi pemasangan VRU. Penelitian ini dilakukan dalam dua tahap yaitu: 1) pengukuran % konsentrasi Lower explosive limit (LEL) dari vapor dengan menggunakan gas tester di Lokasi, 2) analisis kelayakan ekonomi dengan menggunakan data yang didapat. hasil dari penelitian ini adalah tidak ditemukan adanya vapor dan emisi lainnya pada saat VRU beroperasi serta secara keekonomian VRU yang dipasang pada SPBU PT. X Karang Tengah dengan kapasitas unloading 3.000 kL per tahun memiliki NPV pada tahun ke-20 adalah Rp. 2.178.349.743, IRR 22,6%, dan payback period selama pada tahun ke-6 dan apabila dioptimalkan pada SPBU dengan kapasitas unloading 8.000 kL per tahun, maka akan mendapatkan Rp 5.345.145.184, IRR 42,8%, dan payback period pada tahun ke-3.

According to Law Number 22 of 2021 Indonesian Constitution, fuel oil (BBM) is fuel that originates and/or is processed from petroleum. Fuel sold on the market is generally petrol and diesel with various octane and cetane numbers. One of the facilities used to distribute fuel to the public is a Public Fuel Filling Station. Operational activities at gas stations have potential dangers that can cause work accidents, such as vapor from fuel which can cause fires and explosions, and then CO and H2S which can cause health problems for workers, and so on. The aim of this research is to determine the amount of vapor that can be recovered by a Vapor Recovery Unit (VRU), to determine the vapor detected in the gas station environment, and to determine the economic feasibility of installing a VRU. This research was carried out in two stages, namely: 1) measuring the concentration LEL of vapor, CO, and H2S using a gas tester at the location, 2) economic feasibility analysis using the data obtained. The results of this research are that no vapor and other emissions were found when the VRU was operating and and economically, the VRU installed at the PT gas station. X Karang Tengah with an unloading capacity of 3,000 kL per year has an NPV in the 20th year of Rp. 2.178.349.743, IRR 22,6%, and payback period during the 6th year and if optimized at gas stations with an unloading capacity of 8,000 kL per year will get IDR 5.345.145.184, IRR 42,8%, and payback period in the 3rd year."
