Abstract

Abstrak Telah dilakukan inversi terhadap data seismik PSTM 3D lapangan NAJLAA, Cekungan Jawa Barat Utara. Metode yang digunakan yaitu inversi impedansi elastik untuk mengidentifikasi pola penyebaran litologi dan fluida hidrokarbon dari reservoar batupasir di lapisan Z.2210 Formasi Cibulakan. Inversi AVO dilakukan untuk mendapatkan intercept, gradient, reflektivitas impedansi elastik, near angle stack dan far angle stack. Analisis grafik AVO dan atribut angle stack untuk mengetahui respon amplitudo terhadap offset digunakan untuk menentukan kelas anomali AVO. Dari hasil analisis sensitifitas menunjukan bahwa impedansi elastik dengan sudut 30o paling sensitif dalam pemisahan litologi batupasir dan serpih. Sehingga proses inversi impedansi elastik dengan sudut 30o terbukti paling sensitif dalam pemetaan penyebaran litologi. Selanjutnya dilakukan analisis crossplot antara log impedansi elastik sudut 30o terhadap log gamma ray untuk membedakan litologi batupasir dan crossplot antara log lambda-rho terhadap log gamma ray untuk menentukan adanya indikasi fluida hidrokarbon. Hasil analisis AVO menunjukkan bahwa respon pada lapisan Z.2210 termasuk dalam anomali AVO kelas IIp yang terletak pada twt 1794 ms sampai 1799 ms di sumur UI-10. Pemetaan inversi impedansi elastik dengan sudut 30o inline 1141 menunjukkan bahwa litologi batupasir zona target mempunyai nilai 1410 (m/s)2*gr/cc sampai 1570 (m/s)2*gr/cc dengan daerah penyebaran batupasir pada reservoar lapisan Z.2210 memiliki orientasi arah timur laut-barat daya. Kata kunci: Inversi; AVO; Impedansi Elastik Abstract An inversion has been carried out againts the seismic data of PSTM 3D at Najlaa field in the Northern West Java basin. The method used is elastic impedance to identify lithology and hidrocarbon distribution of sandstones reservoir in the layer of Cibulakan Formation, Z.2210. AVO inversion has been carried out to get intercept, gradient, elastic impedance reflectivity, near angle stack, and angle stack. The AVO graph analyzing and angle stack attribute are used to determine amplitude response of the offset used to determine AVO anomaly class. From the result of sensitivity analysis showed that elastic impedance has the most sensitivity in the separation of sandstones lithology and mudstones in the angle of 30 degree. It is approved in the mapping of lithology distribution. Further crossplot analysis has been carried out between elastic impedance log angle in 30 degree againts gamma ray log to distinguish sandstones lithology and crossplot between lambda-rho log to gamma ray log to determine the indication of hidrocarbon fluids. The result of AVO analysis showed the response in the layer Z.2210 included in IIp AVO anomaly located at twt 1794 ms to 1799 ms in UI-10 well logging. Elastic Impedance mapping 30 degree inline 1141 showed that target zone of sandstones lithology has a value of 1410 (m/s)2*gr/cc to 1570 (m/s)2*gr/cc with region spread of the sandstones distribution in reservoir layers Z.2210 which has an orientation toward Northeast-Southwest.

Abstract

The need for oil and gas has led to increased exploration to produce hydrocarbons in various basins and discover new reserves. This was also done in the Kutai basin on the eastern island of Kalimantan using a quantitative correlation between geophysical logs and rock core data and qualitative analysis by analyzing geochemical data derived from the host rock. To determine the characteristics of the hydrocarbon source rock in the three test wells, three types were analyzed, namely organic material richness, organic material type, and maturity level. For the Maau-1, Wahau-1, and Tengkawang-1 test wells, the organic material content has an excellent type to become source rock. The three wells are of medium-special hydrocarbon potential in organic material, making them very likely to produce oil and gas. As for the nature of the material content, the three wells have a mature level of the source rock, making them very potential as the  very good source rock.

Abstract

The research was conducted to determine the hydrocarbon reservoir zone in the LIM-1 well, which was analyzed using quantitative and qualitative methods to assess the reservoir type involving several log data, including gamma ray (GR), neutron (NPHI), and density (RHOB). The quantitative analysis stage is the determination of hydrocarbon content by the crossover of NPHI log data, and RHOB log data with six target zones. The quantitative analysis stage in this study uses Interactive Petrophysics (IP) software version 3.5 on well LIM-1, also with target zone 1 only. The results obtained from qualitative and quantitative analysis at well LIM-1 show that there are three types of reservoirs in the study area from several target zones according to depth, which are dominated by oil, water, and gas.

Abstract

Indonesia’s transition to renewable energy is a pivotal aspect of its strategy to achieve sustainability and reduce greenhouse gas emissions. This study evaluates the impact of green energy policies on renewable power plant investments in Indonesia through a comparative analysis of solar, wind, geothermal, and hydropower projects. Using data from 2015 to 2024, the study examines the effectiveness of feed-in tariffs, tax incentives, and renewable energy mandates in driving investments. The results show that while policies like feed-in tariffs and tax incentives have significantly boosted investment in geothermal and hydropower projects, solar and wind energy sectors face challenges such as low tariff rates and infrastructure deficits. Comparative insights from successful international cases underscore the need for policy stability, grid expansion, and technology-specific strategies. This research provides actionable recommendations to optimize Indonesia’s green energy framework, fostering a more inclusive and sustainable renewable energy sector.

Abstract

The disaster that hit Palu City recently caused changes in the quality of water consumed by the community. To find out whether it is feasible or not, we need a method to detect a water quality system that is easy to implement at an economical price to be used for daily needs. Therefore, a tool is designed to determine the quality of water that is sampled around the Tondo beach using the Fuzzy Logic method. This design was built using the Arduino module by combining four sensors, namely a pH sensor, a TDS sensor, a Turbidity sensor, and a temperature sensor. Water quality in this study was divided into three groups, namely drinking water (UM), washing water (UC), and unsuitable water (TL). The water quality benchmark value is known from combining the results of existing sensor readings, wherein sample 1, the value of water quality measured in the study is in the category not in accordance with the fuzzy value 10, in sample 2,the use of washing uses the fuzzy value of 45.68 and sample three is worth 26.4

Abstract

The Central Sulawesi region is prone to earthquakes, as evidenced by its complex geological structure. Several plates and active fault movements in the vicinity cause this situation. One of the active faults that often causes earthquakes is the Palu-Koro active fault. The city of Palu is one of the areas passing through the Palu-Koro fault. The danger of this earthquake occurrence can be ascertained and assessed using a suitable earthquake location. Within the scope of our investigation, we used a non-linear approach to predict the hypocenter site in the vicinity of the Palu-Koro fault that is active. This Method use oct-tree importance sampling algorithm to generate spatial hypocenter locations. Using the AK135 minimal seismic velocity model, we manually re-picked the arrival times of wave P-waves and S-waves arrival timings of 3,852 and 3,690, respectively, collected by 24 BMKG observation sites from January 2011 to December 2015, utilizing the minimal 1D seismic velocity model from AK135. We employed criteria to ascertain the event's location, including a minimum of four stations exhibiting a distinct beginning of P and S wave arrivals, with a magnitude of at least 3Mw and an average depth ranging from 10 to 20 km. The outcomes of seismic event location identification exhibit improved clustering with inversion, revealing a zero-centered Gaussian distribution, where more time discrepancies, both positive and negative, correspond to increased estimating mistakes. According to this research, the Palu-Koro active fault line's primary shallow seismic zone is the most prominent feature in the area and confirms the existence of active land faults that cause earthquake events by conducting a process of determining a locally updated 1D velocity model that will be used to determine a more precise relocation of the hypocenter used to interpret the subsurface model of the research area.
