EVALUATION OF SUSTAINABILITY ASSESSMENT POST CHANGES IN THE MANAGEMENT OF THE NATURAL RESERVE TO THE NATURAL TOURISM PARK IN KAMOJANG AREA, WEST JAVA, INDONESIA
No full textThe area of Kamojang Nature Tourism Park, which was originally only 255 hectares, has expanded to 2,391 hectares following a changes in the Nature Reserve area. This change has raised concerns and objections from various parties, as it is considered to open opportunities for exploitation, threaten biodiversity, and potentially trigger tourism activities that may degrade the environmental quality of the areaThis study aims to analyze the sustainability status index of the Kamojang Natural Tourism Park following the status downgrade from a Nature Reserve to a Natural Tourism Park. A descriptive qualitative approach used, utilizing the Multi-dimensional Scaling model to determine sustainability status. The sustainability index status of the Natural Tourism Park of Kamojang is subdivided from each of dimensions: natural tourism management, ecological or environmental, economic, disaster, socio-culture aspects. In addition, this study identifies sensitive attributes that influence the sustainability status of the Natural Tourism Park of Kamojang, which serve as a basis for developing appropriate policies to ensure the sustainable and conserved Natural Tourism Park (NTP). The results show that the sustainability index status across all five dimensions are below 50 which derived from five dimensions (tourism management, disaster, ecology/environment, economy, socio-culture) that the status is regarded as bad and less sustainable specifically of the NTP situated in of Pasirwangi, Paseh, Pacet and Kertasari sub-districts. These finding highlights the critical need for integrated, and multidimensional interventions to address systemic vulnerabilities and promote sustainable development within rural tourism ecosystems. Therefore, a comprehensive strategy for sustainable tourism development is essential in various aspects ranging from planning, capability and land feasibility to determining the carrying capacity and mitigation as well as developing activities and tourist attractions
SUSTAINABLE WATER MANAGEMENT IN UNIVERSITIES: PERCEPTIONS, BEHAVIOURS, AND CHALLENGES
No full textUniversities are increasingly adopting the “living laboratory” model to implement and evaluate sustainability innovations. These settings enable students, staff, and stakeholders to co-create and test real-world solutions, including those related to water use. Universitas Indonesia promotes sustainability through an integrated approach encompassing policy development, academics programs, and infrastructures. Prior studies using the Theory of Planned Behavior (TPB) have demonstrated that attitudes and perceived norms significantly influence sustainable behavior. However, limited research has examined how these dynamics operate within Indonesian universities or how university-based initiatives may contribute to broader urban water management. This study addresses that gap by examining perceptions, behaviors, and challenges related to sustainability in a university, while also assessing the relevance of campus-based interventions to inform wider urban sustainability transitions. A cross-sectional, non-probability survey was conducted with 87 students and staff at the Health Sciences Cluster Building (RIK UI), Universitas Indonesia. A structured questionnaire was use to assess participants’ understanding of sustainability, perceptions of institutional performance, initiative effectiveness, course evaluations, and behavior frequency. Validity and reliability testing confirmed internal consistency. Chi-square tests were used to examine associations among variables, qualitative analysis, and multiple linear regression was used to identify behavioral predictors. Respondents identified inadequate infrastructure and ineffective communication as barriers. Despite high level of awareness, reported engagement in water-saving practices remained low. Chi-square results revealed significant associations between perception and behavior. Regression analysis revealed that sustainability understanding and perceptions of institutional performance were significant predicted of the frequency of sustainable behaviour, aligning with TPB’s attitude and subjective norm. These findings show that awareness alone is not sufficient—targeted sustainability education is needed to motivate behavior change. When embedded in university living laboratories, such education can help bridge the awareness–action gap and support scalable solutions for urban water governance

Analysis of Leak Testing Planning for Carbon Dioxide Piping Systems in the Development of Carbon Capture, Utilization, and Storage Facilities in the Bintuni Basin
No full textCarbon Capture, Utilization, and Storage (CCUS) technologies have become a key strategic response to global efforts to reduce CO2 emissions. This study presents a leak testing strategy designed for a carbon dioxide (CO₂) piping system as part of a Carbon Capture, Utilization, and Storage (CCUS) project in the Bintuni Basin, West Papua, Indonesia. This study aims to ensure the system is properly prepared before commissioning by designing a leak test plan that is both practical and technical, based on ASME B31.3, ASME PCC-2, and API STD 520 Part 1. We conducted the process, which involves identifying the system boundaries, selecting the test medium, determining the test pressure, sizing the pressure relief valves, calculating the exclusion zone, and a qualitative risk assessment. The findings highlight the importance of performing a tightness test using nitrogen gas at 90% of the pipe\u27s design pressure, especially for newly installed sections connected to existing LNG facilities. Based on technical analysis, this study provides a clear and applicable reference for field implementation of leak testing in CCUS projects
Implementation of Reliability Centered Maintenance on Crude Booster Pump
No full textCrude oil booster pump is one of the critical equipment in oil refinery operations. In aging plants that have been operating for more than 25 years, where reliability and maintenance issues on equipment often cause operational disruptions and even unplanned shutdowns. This study aims to develop a structured reliability-centered maintenance (RCM) strategy for crsude oil booster pump systems that is also in line with the principles of asset integrity management system (AIMS). This methodology follows the RCM II approach, starting with system function analysis, failure mode identification, and criticality assessment through Failure Mode, Effect, and Criticality Analysis (FMECA) to determine the Risk Priority Number (RPN) value that looks at the severity, occurrence, and detection rankings to support the priority and selection of maintenance tasks. The results of the study indicate that mechanical seal leakage and bearing wear are the most dominant failure modes, which contribute significantly to operational disruptions. Based on the RCM decision logic, the selected maintenance strategy includes condition monitoring and scheduled restoration tasks. These findings support the integration of RCM results into an asset management framework, which offers practical recommendations to improve pump reliability, reduce corrective maintenance, and support long-term plant availability goals
