Abstract

Pertumbuhan pesat kendaraan listrik di DKI Jakarta sebagai pusat mobilitas nasional mendorong kebutuhan akan ketersediaan infrastruktur Stasiun Pengisian Kendaraan Listrik Umum (SPKLU) yang tersebar secara strategis. Namun, pembangunan SPKLU menghadapi berbagai tantangan, seperti keterbatasan lahan, kepadatan penduduk, aksesibilitas, serta variabel spasial dan lingkungan lainnya. Tanpa pendekatan perencanaan lokasi yang tepat dan berbasis data, pembangunan SPKLU berisiko tidak optimal dan dapat menghambat transisi menuju sistem transportasi berkelanjutan. Penelitian ini bertujuan menentukan lokasi optimal SPKLU di DKI Jakarta dengan mengintegrasikan metode Analytical Hierarchy Process (AHP) dan Geographic Information System (GIS). AHP digunakan untuk menentukan bobot prioritas dari sejumlah kriteria, seperti aksesibilitas, kepadatan kendaraan listrik, ketersediaan lahan, kedekatan dengan sumber listrik PLN, dukungan kebijakan pemerintah, serta faktor lingkungan. Bobot tersebut kemudian diintegrasikan ke dalam GIS melalui pendekatan weighted overlay guna menghasilkan peta zona prioritas pembangunan SPKLU. Penelitian ini diharapkan memberikan kontribusi teoritis dalam pengembangan metode pemilihan lokasi berbasis multi-kriteria dan spasial, serta kontribusi praktis bagi pemerintah, investor, dan pemangku kepentingan dalam mendukung percepatan adopsi kendaraan listrik dan pembangunan infrastruktur yang tepat sasaran dan berkelanjutan.

Abstract

The oil and gas industry remains a strategic pillar for national energy security, yet it faces significant operational challenges as production fields mature. A critical issue is the exponential increase in produced water, which often surpasses the design limits of existing Produced Water Treatment Systems (PWTS). This research evaluates the investment feasibility of upgrading the PWTS capacity at a major gas processing facility where current water production has reached 3,110 BWPD, significantly exceeding the 2,000 BWPD design capacity. To address this, a hybrid framework was developed by integrating Technical and Economic Risk Assessments. Technical risks were quantified using Failure Mode and Effect Analysis (FMEA), involving 28 failure modes across seven primary equipment units. To mitigate the subjectivity of expert judgment, a Monte Carlo Simulation with 10,000 iterations was implemented, followed by a Risk Matrix to translate technical failures into quantifiable "Expected Costs." The Economic Risk Assessment was conducted via Cost-Benefit Analysis (CBA), incorporating these expected costs as avoided-loss benefits. The results identify an optimal upgrade capacity of 6,000 BWPD, which yields a Net Present Value (NPV) of USD 84.94 million, an Internal Rate of Return (IRR) of 80.88%, a Benefit-Cost Ratio (BCR) of 16.59, and a Payback Period (PP) of 24 months. Furthermore, sensitivity analysis underscores the project’s robustness, demonstrating resilience against operational expenditure (OPEX) hikes of up to 50%, while establishing a critical production decline tolerance of -1.5% per day. This integrated methodology provides a robust, data-driven decision-making tool for managing high-risk energy infrastructure investments.

Abstract

Religious moderation is a crucial element in maintaining social harmony in Indonesia, especially in cities with religious diversity such as Semarang. Balinese Hindu traditions play a significant role in strengthening the values of tolerance and mutual respect through various cultural and religious practices. This study analyzes how Balinese Hindu traditions, including the Melasti ceremony and the Nyepi celebration, contribute to religious moderation in Semarang. This study uses a narrative descriptive approach with the aim of understanding in depth how Balinese Hindu traditions contribute to promoting religious moderation in Semarang. The data collection method was carried out through direct observation,in-depth interview, And Documentation analysis. Observations were conducted by observing religious practices and cultural activities involving the Balinese Hindu community as well as the participation of non-Hindus in religious events. Interviews were conducted with religious leaders, community leaders, and individuals involved in interfaith activities to gain a broader perspective on social interactions and the application of religious moderation values. Documentation analysis included literature studies from academic journals, official reports, and relevant statistical data to strengthen the research findings. The results of the study indicate that interfaith interactions in the Balinese Hindu tradition can increase understanding and respect between religious communities, as well as strengthen social harmony. In addition, cultural festivals and interfaith activities play an important role in building dialogue and cooperation between communities. These findings confirm that the Balinese Hindu tradition not only functions as a cultural identity, but also as an effective means of promoting religious moderation in a multicultural environment.
