Studi Perhitungan Potensi Cadangan Panas Bumi pada Lapangan Jailolo di Wilayah Halmahera
Get PDFAbstrakLapangan Panas Bumi Jailolo terletak di wilayah Halmahera, Maluku Utara. Lapangan panas bumi ini direncanakan untuk dikembangkan sebagai pemenuhan kebutuhan energy listrik di wilayah Indonesia Timur. Sebelum dilakukan pengembangan lapangan panas bumi maka perlu dilakukan perhitungan potensi cadangan panas bumi. Dalam perhitungan potensi cadangan panas bumi menggunakan metode volumetric dan metode monte carlo yang merujuk pada SNI No. 13-6169-1999, karena lapangan panas bumi Jailolo belum ada sumur eksplorasi dan belum adanya data produksi sumur. Parameter yang digunakan dalam perhitungan diperoleh dari data hasil kegiatan survei pendahuluan dan geotermometer berupa data ketebalan, luas serta temperatur reservoir. Sedangkan parameter lainnya yang belum diperoleh dari kegiatan survei pendahuluan didasarkan pada SNI No. 13-6482-2000. Hasil perhitungan potensi cadangan terduga panas bumi menggunakan metode volumetrik dengan luas area prospek sekitar 6 km², ketebalan reservoir sekiar 1500 m dari permukaan, dan temperatur reservoir 200 – 220 °C diperoleh sebesar 98.38 MWe, sedangkan hasil perhitungan metode monte carlo diperoleh potensi cadangan terduga sebesar P10 = 14.88 MW, P50 = 29.44 MW dan P90 = 50.26 MW. AbstrakThe Jailolo Geothermal Field is located in the Halmahera region, North Maluku. This geothermal field is planned to be developed as a fulfillment of electrical energy needs in Eastern Indonesia. Before developing a geothermal field, it is necessary to calculate the potential of geothermal reserves. In calculating the potential of geothermal reserves using the volumetric method and the monte carlo method which refers to SNI No. 13-6169-1999, because there is no exploration well in the Jailolo geothermal field and no well production data. The parameters used in the calculations are obtained from data from preliminary survey activities and geothermometers in the form of thickness, area and reservoir temperature data. Meanwhile, other parameters that have not been obtained from the preliminary survey activities are based on SNI No. 13-6482-2000. The results of the calculation of potential geothermal reserves using the volumetric method with a prospect area of about 6 km², a reservoir thickness of about 1500 m from the surface, and a reservoir temperature of 200 – 220 °C obtained 98.38 MWe, while the results of the calculation of the Monte Carlo method obtained potential reserves of estimated amounted to P10 = 14.88 MW, P50 = 29.44 MW and P90 = 50.26 M
A Review of Strategies for Managing Uncertainty in Crude Oil Prices by Indonesian Oil and Gas Companies and the Government
Get PDFThe world oil and gas market has experienced uncertainty since 2014 until now. Fluctuating supply and demand, geopolitical tensions, and shifts in energy policies cause this. In addition, at the beginning of 2020, there was a prolonged pandemic, which made oil and gas conditions even more erratic. This uncertainty significantly impacts the Indonesian state, especially the Indonesian government and oil and gas companies operating in Indonesia. Various methods have been taken to mitigate the impact of this uncertainty, both by the government and oil and gas companies. Therefore, this study aims to conduct a literature review regarding the strategies undertaken by the Indonesian government and oil and gas companies in Indonesia to address the uncertainty in world oil prices since 2018. This research was conducted using the literature method. A review of scientific articles that have been published from 2018 to 2022. The selected articles follow the research objectives and comply with the inclusion and exclusion criteria set at the outset. Results of the literature process the review obtained as many as 67 articles that discussed various strategies carried out by the government and oil and gas companies. The discussion results show three strategies carried out by oil and gas companies in Indonesia: cutting costs, implementing digitalization, and diversifying into renewable energy projects. Meanwhile, the strategy undertaken by the Indonesian government includes providing fiscal incentives, investing in infrastructure that supports the oil and gas sector, deregulating the oil and gas sector, and encouraging the use of renewable energy as an alternative energy source. These various strategies aim to increase efficiency, reduce costs, diversify energy sources, and increase competitiveness in Indonesia\u27s oil and gas sector to deal with the uncertainty of world oil prices
Kajian Potensi Panas Bumi Sebagai Renewable Energy dan Pemanfaatanya pada Daerah Prospek Panas Bumi Gunung Telomoyo Magelang
Get PDFAbstrakEnergi konvensional merupakan sumber energi utama yang masih digunakan hingga saat ini, seperti batubara dan minyak bumi. Namun, sumber energi tersebut jumlahnya semakin menipis karena tidak bisa untuk diperbarui dan memerlukan waktu yang lama dalam pembentukannya, sedangkan kebutuhan energi yang selalu meningkat. Sehingga, dibutuhkan sumber energi baru dan terbarukan yang berkelanjutan, salah satunya adalah energi panas bumi. Potensi panas bumi di Indonesia sangat tinggi, sekitar 40% atau 29.000 MW total panas bumi dunia berada di Indonesia, salah satunya di komplek Gunung Telomoyo. Penelitian bertujuan untuk mengindikasikan potensi persebaran dan karakteristik sumber energi panas bumi Telomoyo agar dapat dikembangkan lebih lanjut ke tahap eksplorasi dan eksploitasi. Metode penelitian berupa studi literatur dan survei lapangan untuk mendapatkan data sekunder dan primer. Dari penelitian ini, didapatkan hasil berupa titik persebaran manifestasi panas bumi, peta geologi, peta geomorfologi, potensi, dan karakteristik panas bumi di komplek Gunung Telomoyo. Terdapat tiga sumber manifestasi panas bumi, diantaranya yaitu berada di mata air panas Candi Dukuh, Pakis Dadu, dan Candi Umbul, dengan karakteristiknya yang didukung oleh data geokimia, geologi, dan geomorfologi. Panas bumi daerah ini berpotensi untuk substitusi energi konvensional dan juga potensial untuk eksplorasi dan eksploitasi, maka dari itu diperlukan studi lebih lanjut untuk optimalisasi sumber panas bumi di Gunung Telomoyo.Kata kunci : manifestasi, panas bumi, Telomoyo AbstrackEnergy is something that cannot be separated from human life. Over time, conventional energy such as coal and oil will be depleted because it takes a very long time to produced. To meet the increasing demand for the higher energy, new sustainable energy sources are needed. Renewable energy has a very high potential but its utilization is not optimal. One of the renewable energy sources is geothermal. Geothermal is a source of heat energy that is formed naturally below the earth\u27s surface which comes from heating rocks and water along with others elements originating from magmatism activity in the earth\u27s crust. Indonesia has the largest geothermal potential in the world because it’s located in the Indo-Australian and Eurasian subduction zones, leaving many active volcanoes and their potential. The Mount Telomoyo complex is one of the geothermal prospect areas which is indicated by the appearance of manifestations to the surface as hot springs and alteration of rocks. In the geothermal area of Mount Telomoyo, there are 3 heat sources as manifestations, including the hot springs of Candi Dukuh, Pakis Dadu, and Candi Umbul. In this study, field survey methods and literature studies were used which in the end obtained results in the form of distribution points of manifestations, geological maps, landform maps, and geothermal potential.Keywords : manifestation ,geothermal, , Telomoyo
Relaksasi Otot Progresif Untuk Menurunkan Tingkat Stres Pada Waria yang Terinfeksi HIV/AIDS
Get PDFObjective of this research is to understand the effectivity of the progressive muscle relaxation in order to decline the stress level among the HIV/AIDS infected ladymen. We propose the hypothesis that there will be a decline stress level among those HIV/AIDS ladymen just after they received the progressive muscle relaxation. Five ladymen participate in this research and their stress level are moderate untill high. Design of this research is the one group pretest-posttest. Instrument of data collection is the DASS 42 Stress Scalle. We ask participants to complete the scale just before and after receiving five times progressive muscle relaxation. This research reveals that there is a significant difference in stress level between before and after receiving five timer progressive muscle relaxation (Z = -2,032, p = .042 or p< .05). The mean scores for the stress level are 26.00 and 15.00 just before and after receiving the progressive muscle relaxation respectively. Based on that data, we come to conclusion that the progresssive muscle relaxation is effective in reducing stress level among the infected HIV/AIDS ladymen
