Abstract

The SPALD Project is currently undergoing a survey phase to gather data on perceptions and experiences related to risks. Data analysis has been conducted using statistical methods to explore the relationship between risk identification and risk management effectiveness in the context of the SPALD project. The analysis results indicate a significant positive correlation between risk identification and risk management effectiveness, with a correlation coefficient of 0.75 (p < 0.01). Regression analysis indicates that the risk identification variable significantly predicts risk management effectiveness (F(1, 123) = 64.32, p < 0.001), with a coefficient of determination (R squared) of 0.52. These findings affirm that enhancing the risk identification process meticulously and comprehensively can enhance risk management effectiveness in the SPALD project in DKI Jakarta. Recommendations for this project include initial risk identification, the use of adaptive risk management systems, implementation of analysis-based mitigation strategies, and team awareness enhancement. These recommendations aim to enhance risk management effectiveness, achieve project objectives, and mitigate potential negative impacts.

Abstract

This study aims to analyze the impact of various performance factors on contractor performance in the implementation project, as part of the National Police's institutional transformation toward a predictive, responsive, and transparent work system. The performance factors analyzed include managerial competence, work experience, communication, and time management. Using a questionnaire and Partial Least Square (PLS) analysis, the study finds that managerial factors (P-value 0.000) and occupational safety and environment (K3L) (P-value 0.016) significantly influence contractor performance. However, legal and licensing, financial, technical, and social aspects do not show significant effects. The study suggests focusing on improving managerial training and enhancing K3L standards, while also maintaining compliance with licensing and social relationships. This research highlights the importance of management and safety training in educational settings to improve professional performance in construction projects.

Abstract

Residential area of Jatibening Housing located in Jln. Caman Raya No. 2,Jatibening Village, Pondok Gede Subdistrict, Bekasi City. The condition of drainage in the Jatibening Permai Housing is currently not as good as a whole. This is evidenced by the flooding that still occurs when the rainy season arrives. So that the evaluation and re-planning of the drainage channel must be done by analyzing the calculation of Cross Section data and rainfall data so that the drainage channel dimensions are obtained. This is so that Jatibening Permai Housing is no longer a flood-affected area due to high rainfall. The results of the study show that the reuse period used in channel planning drainage at Jatibening Permai Housing is a 2-year return period with the Type III Log Pearson Method. The planned flood discharge was analyzed by the rational method based on rainfall intensity from the maximum daily rainfall data in the 10 year period of 212.05 mm / hour. The maximum flood discharge of the Jatibening Permai residential area is 1,650 m ^ 3 / second. While planning an infiltration pond in the form of a rectangle measuring 75 m x 55 m with a depth of 5 m can accommodate a volume of rainwater of 20,625 m3.

Abstract

With the limited availability of hydrograph data, it becomes an obstacle for water building planning. This obstacle makes HSS models provide considerable benefits for water building planning. Ideally, each watershed (DAS) has a Unit Hydrograph with its own characteristics. This research was conducted with the aim of observing the hydrograph characteristics of observations in each watershed and all watersheds in the province of South Sulawesi. This study was conducted to model the Alpha equation with the influence parameters of watershed area (A), river length (L), riverbed slope (S), Form factor (FD) and time concentration (tg). With the Watershed Form Factor it has an influence on the Alpha value so it is very helpful in planning water structures. The modeling analysis used is nonlinear regression because it has different data variants based on the homogeneity test carried out. It is hoped that the resulting Alpha value can match the real conditions in the environment so that it will have an impact on a more efficient design.

Abstract

Scour on bridge piers is a major problem in hydraulic engineering, reducing structural stability and accelerating foundation failure. This phenomenon occurs due to the interaction between airflow and bridge structural elements, resulting in the formation of scour holes that potentially reduce the bearing capacity of the soil around the piers. In areas with strong currents, seasonal changes in discharge, and unstable riverbed conditions, the risk of scour is even higher. The impact of scour damage not only reduces the operational lifespan of bridges but also leads to high rehabilitation costs and increases the potential for structural failure, which can endanger user safety. This study aims to analyze various scour mitigation methods that can be applied to bridge piers, including the use of protective materials such as riprap, gabions, and geotextiles; a geotechnical engineering approach that includes soil stabilization and riverbed contour modification; and the development of pier structural designs that are more adaptive to variations in flow patterns. The study was conducted through an in-depth literature review of previous research, an analysis of the effectiveness of each method under various hydrodynamic conditions, and an evaluation of the cost. The results of this study are expected to produce comprehensive recommendations regarding the most effective, efficient, and environmentally friendly mitigation strategies to reduce the rate of scour. Furthermore, this study provides direction in planning bridge designs that are more resilient to changes in flow and sedimentation, thereby extending the service life of the structure, reducing long-term maintenance costs, and improving user safety.

Abstract

This study analyzes the decision-making process in UMKM Gumantea, a herbal tea micro-enterprise originating from Yogyakarta and operating in Karawang. The research focuses on four managerial aspects: labor management, capital allocation, raw material decisions, and marketing strategies. A qualitative descriptive method with a single case study approach was applied through in-depth interviews, observations, and documentation. Findings reveal that decision-making is shaped by resource limitations and the central role of the owner. Labor decisions are intuitive and flexible but lack long-term efficiency. Capital decisions prioritize financial safety, resulting in gradual business growth. Raw material decisions are the most strategic, emphasizing quality differentiation through consistent sourcing from Yogyakarta. Marketing decisions rely on simple yet adaptive strategies such as the “Jumat Berkah” promotion and basic social media utilization. These findings align with Simon’s bounded rationality, Scott & Bruce’s decision-making styles, and Robbins’ decision stages. The study concludes that UMKM decisions tend to be practical, situational, and experience-driven, highlighting the need for strengthened managerial systems to enhance long-term effectiveness.

Abstract

The Centralized Domestic Wastewater Management System (SPALD-T) projects play a crucial role in improving urban sanitation but face various risks that can affect project performance. This study aims to analyze the influence of risk factors on SPALD-T project performance in DKI Jakarta. Using a quantitative approach with a cross-sectional design, data were collected through a survey of 125 members of the SPALD-T project team. The questionnaire used has undergone validity and reliability tests to ensure accurate measurement of variables. Multiple regression analysis was employed to test the relationship between risk factors and project performance. The results indicate that waste management risk has a significant and positive influence on project performance, with a regression coefficient of 0.188 and a p-value of 0.001. Meanwhile, technical risk shows a positive trend but is not statistically significant, with a regression coefficient of 0.104 and a p-value of 0.078. These findings emphasize the importance of a comprehensive risk management approach, especially in waste management aspects, to improve SPALD-T project performance. This research contributes to the development of more effective risk mitigation strategies in the context of sanitation infrastructure projects in Indonesia and highlights the need for further research on the interaction between various types of risks in influencing project performance.
