Abstract

This study develops an integrated system dynamics and probabilistic Monte Carlo simulation framework to evaluate Indonesia’s Petroleum Buffer Reserve (PBR) strategy in alignment with Perpres 96/2024 and the nation’s broader energy security agenda. Monte Carlo simulation results reveal that only the scenario characterized by full import availability is capable of achieving the mandated 10.17-million-barrel reserve target, while all other scenarios consistently fail to accumulate sufficient stock under uncertainty. The probabilistic analysis further shows that this scenario yields a probability exceeding 98% of meeting or surpassing the target, in contrast to the near-zero success rates observed under restricted import conditions. Days-of-cover optimization highlights an additional strategic vulnerability: the current PBR target corresponds to only about 12 days of crude import protection. Building on the system’s dynamic behavior, this study recommends a minimum reserve target of 30 days as an immediately achievable benchmark. A 60-day reserve is identified as a feasible medium-term objective, provided that replenishment rates and storage capacity are enhanced. Achieving a 90-day reserve, consistent with international strategic stockpiling standards, would require substantial investment and diversification of supply sources. These findings underscore Indonesia’s structural dependence on imported crude oil and emphasize the need for assertive replenishment policies to strengthen national energy resilience

Abstract

An increase demand for reusable cameras among the millennial and Z-generation in Indonesia has created a significant environmental dilemma, considering the consequently increasing production of electronic waste. Although the principle of circular economy has been adapted in various electronic industry sector, its implementation in particularly the camera industry is still left to explore. This study aims to design and validate a comprehensive circular business model for reusable cameras in Indonesia that can measurably reduce electronic waste from disposable cameras while maintaining economic and environmental value creation To achieve this objective, the study applies a circular business model canvas integrated with a qualitative case study on reusable camera usage in Indonesia, a systematic literature review on circular economy practices in the electronics sector, and a product sustainability assessment using quantitative metrics. This paper concludes that the proposed circular business model for reusable cameras represents the most suitable development option because it simultaneously reduces e‑waste from disposable cameras and enhances economic and environmental value creation in Indonesia. This study also develops three hybrid business model strategies – ‘ownership plus, ‘try-before-you-buy’, and ‘community-based ownership pools’ – all of which accommodate consumer ownership preferences in Indonesia while maintaining the circular economy principles. This paper concludes by highlighting the operability of the circular business model for camera and its potential contribution to the sustainable development goals. This notwithstanding, its implementation requires multi-stakeholder collaboration, investments in digital infrastructure, capacity building, and government support on regulations.

Abstract

Objective: This study aims to develop a holistic framework for assessing the reliability of clinical laboratory equipment in vertical hospitals in Indonesia. Clinical laboratories play a strategic role in supporting National Health Insurance and in achieving the Sustainable Development Goals (SDGs) across economic, social, and environmental dimensions. Reliable maintenance systems are crucial for ensuring equipment reliability, maintainability, availability, and safety. Method: A comprehensive literature review of international journals was conducted to identify existing models and methodologies for reliability assessment. The proposed framework integrates reliability engineering, sustainability principles, and VUCA (volatility, uncertainty, complexity, ambiguity) concepts. The model consists of sub-assessment sections covering pre-analytical, analytical, and post-analytical stages, as well as equipment reliability, logistics and warehousing, and continuous equipment monitoring. Results: The framework provides a structured approach for identifying factors that influence the reliability of laboratory equipment, enabling effective assessment and problem-solving in clinical laboratories. It facilitates continuous evaluation, supports maintenance planning, and aligns with safety and quality standards. Novelty: Integrating reliability, sustainability, and VUCA concepts into a single, holistic framework for clinical laboratory equipment in Indonesian vertical hospitals. The proposed framework provides practical guidance for hospital policymakers and managers to ensure accurate testing results, optimize equipment performance, enhance patient safety, and support sustainable healthcare operations. By strengthening the reliability of diagnostic services and improving the quality and accessibility of healthcare delivery, this framework contributes to achieving SDG 3 (Good Health and Well-Being).

Abstract

Kite strings in Indonesia are crafted by local artisans who have learned from their predecessors, but the industry struggles to deliver quality products that meet customer standards. A Systematic approach to this problem could involve designing a business intelligence (BI) system to improve decision-making. Based on the main premises of the kite string industry, this paper focuses on developing a causal loop diagram (CLD) model as a first step toward designing an effective BI system for the kite string industry. The CLD model captures the relationships between core variables and brain areas, offering crucial insights into customer perceptions, production quality, and market dynamics. Based on data up to October 2023, the study uses a systematic approach to pinpoint the feedback loops enabling product quality and business performance. This framework can be used as a strategic approach to assist in decision-making, refine operational processes, and enhance overall product quality. This research provides a new perspective to the literature by combining systems thinking into BI system design under the context of traditional industries as an elaboration of findings aimed to gain a competitive advantage in Indonesian kite string business practices.

Abstract

Secure Reliable Transport (SRT) is increasingly used for IP-based live-broadcast contribution because it enables low-latency delivery, packet recovery, and encrypted transport over public networks. However, its practical value depends on measurable performance under real operating conditions and disciplined operational control. This study evaluates the implementation of SRT in live football league and volleyball broadcasts using bounded case evidence from operational records, questionnaires, and focused interviews. The analysis links event-level Quality of Service (QoS) behavior with operational deployment indicators and compares SRT-based contribution with conventional IP transport and satellite contribution. The evaluated indicators include latency, effective packet loss after recovery, service interruption events, recovery time, bitrate stability, setup time, onsite staffing, and operational expenditure. The findings show that SRT provides a practical latency-reliability trade-off relative to regular best-effort IP transport and a lower deployment-cost profile than satellite contribution under the observed conditions. Stable implementation depends on consistent parameter settings, redundancy planning, monitoring ownership, and incident escalation discipline. This study offers a reproducible, engineering-oriented case-evaluation structure for assessing SRT deployment and improving reliability and operational efficiency in IP-based live broadcasting.
