Abstract

The electricity distribution network plays an important role in distributing electrical energy from substations to customers. At the Bandung PT. PLN (Persero) ULP Bengkalis feeder, there are still disruptions that cause blackouts and reduce service quality. This study aims to analyze the causes of disruptions using the Fault Tree Analysis (FTA) method to identify the dominant factors and root causes. The methods used include literature studies, observations, interviews, and data collection on disruptions from January 2025 to Desember 2025 This study was motivated by the limitations of previous studies, which generally used Fault Tree Analysis (FTA) only in a descriptive manner without a quantitative approach and did not consider the influence of local factors on power distribution network outages. Therefore, this study aims to develop a semi-quantitative, probability-based FTA approach and to examine the characteristics of outages in the Bengkalis region. The scientific contribution of this study lies in the integration of probabilistic analysis into FTA and the strengthening of risk-based recommendations to improve the reliability of the electrical distribution system. Animals such as birds, squirrels, or other creatures can cause disruptions by coming into contact with or bridging conductors, which can potentially cause short circuits. The high frequency of interactions between electrical networks and their surroundings, combined with a lack of monitoring and protection of the networks, makes these two factors more significant than other causes. When comparing internal and external disruptions, it is evident that external disruptions account for a larger proportion—approximately 59% of total disruptions—while internal disruptions account for about 41%. This confirms that the reliability of the distribution system in the study area is more heavily influenced by external factors than by the technical condition of the equipment itself.

Abstract

Subak is a traditional irrigation management system in Bali that integrates social, religious, and technical dimensions within agricultural practice through collective agreements among farmers. This study examines the influence of Nabdab Yeh, the water allocation mechanism employed by the Subak institution on the intake operation of Mambal Weir, which supplies irrigation water to 43 Subak units within the Tukad Ayung Irrigation Area. Quantification Analysis I was applied to assess the impact of four principal determinants, namely antecedent precipitation, ponding depth, water demand, and Paddy cultivation percentage. Each determinant was systematically categorized and converted into binary variables to formulate a predictive model. The resulting model yielded an R-total value of 0.78, indicating a strong correlation and high predictive accuracy. Partial correlation analysis revealed that antecedent precipitation (R-partial = 0.515) exerted the most dominant influence, followed by ponding depth (0.470), while water demand (0.249) and Paddy percentage (0.220) demonstrated comparatively lower significance. These findings affirm that climatic and hydrological conditions constitute the primary determinants governing intake operations, whereas agricultural cropping patterns function as an adaptive response to prevailing water availability. The developed model provides a scientific basis for adaptive irrigation management while sustaining the local ecological wisdom inherent to the Subak system.

Abstract

Lakes play an important role in supporting freshwater resources, ecosystems, and socio-cultural activities. However, increasing sedimentation has become a major environmental issue that can affect lake morphology and ecological functions. This study aims to analyze sediment accumulation in Lake Tamblingan and interpret its implications using the Tri Hita Karana framework. Bathymetric surveys were conducted using a Midas Valeport single-beam echosounder with 200 m transect spacing. The data were processed using Civil 3D and ArcGIS to generate bathymetric maps for 2023 and 2024, and sediment thickness was estimated through depth comparison. The results show that Lake Tamblingan experienced sediment accumulation reaching approximately 1,56 m, indicating a significant lake shallowing process. This condition may reduce lake storage capacity, increase turbidity, and potentially affect ecological stability as well as socio-cultural activities surrounding the lake. Integrating bathymetric analysis with the Tri Hita Karana perspective highlights the importance of holistic lake management that considers environmental, social, and spiritual dimensions.

Abstract

In every construction project implementation, what is often a source of problems and disputes is project delays where debates about who and what are the causes and also demands between the owner and the implementer. This study aims to identify the factors causing delays that have the potential to cause disputes. The method used is descriptive statistical analysis. After obtaining the factors causing delays that have the potential to cause disputes, the second stage questionnaire was distributed again to see the level of agreement of each cause of project delays that have the potential to cause disputes. The results of this study found 53 variables that were successfully identified as causes of construction project delays that have the potential to cause disputes. For the results of the factor analysis, it was found that the most dominant factor causing construction project delays that have the potential to cause disputes was the coordination, control and evaluation of work. The coordination, control and evaluation of work factors had the largest percentage variance value among the other formed factors, amounting to 49.914%.
