Abstract

Infrastructure development in Indonesia is a national strategic program that must be achieved because it concerns the people’s livelihoods. The government is currently undertaking various efforts to attain massive-scale infrastructure development throughout the national territory. Central Papua Province is a province in eastern Indonesia that requires infrastructure development to meet the needs and rights of the community to access development and improve community welfare in various fields. The unit price of building materials for infrastructure development that is effective and efficient is crucial in Central Papua, given the limited accessibility, which results in the unit price of infrastructure development being expensive. This study aims to compile factors that influence the high unit price of infrastructure development in Central Papua based on logistics costs. Through quantitative and qualitative methods (mixed methods), this study will produce factors that are considered significant in influencing the high unit cost of infrastructure development. The quantitative method will be carried out through secondary data processing from projects completed from 2020 to 2024 to map the costs considered dominant in influencing the unit price of infrastructure development. Meanwhile, the qualitative method is carried out through in-depth interviews with experts, including government, contractors, and logistics service providers, to confirm factors considered influential in the unit cost of infrastructure development in Central Papua. The results of this study will have a direct impact on the government's efforts to determine the unit cost of infrastructure development based on factors that are considered to have a significant influence.

Abstract

Road maintenance costs play a critical role in government budgeting, as they represent a recurring expenditure required to sustain transportation infrastructure performance and traffic safety. Accurate cost prediction enables long-term efficiency by ensuring that maintenance budgets are allocated appropriately. This study aims to develop a predictive model for road maintenance cost using the Extreme Gradient Boosting (XGBoost) algorithm, optimized through iterative training to improve prediction accuracy based on deviations between predicted and actual costs. Model performance was evaluated using Root Mean Square Error (RMSE), Mean Absolute Percentage Error (MAPE), and the coefficient of determination (R²), all of which indicate a strong model fit and high predictive reliability. The model was developed using simulated and empirical data from 30 road sections with varying characteristics, incorporating key predictors such as road length, cold mix asphalt, asphalt emulsion, diesel fuel, gasoline, water consumption, working area, asphalt removal volume, and labor requirements. The results demonstrate that the proposed XGBoost-based model can effectively estimate maintenance costs and associated resource requirements. The findings provide practical insights for government agencies in planning material usage and workforce allocation for road maintenance activities.

Abstract

The high level of turnover intention has become a significant issue in human resource management as it greatly affects the sustainability of an organization. Therefore, it is necessary to understand the factors that influence employees’ intentions to leave their jobs, both from individual and organizational perspectives. This study employs a quantitative approach with a sample of 200 respondents selected using purposive sampling. Data were collected through a questionnaire using a Likert scale and analyzed using SPSS version 25, including validity, reliability, and classical assumption tests to ensure the feasibility of the model. The results show that personality traits have a positive and significant effect on turnover intention. This indicates that differences in individual characteristics influence employees’ tendencies in making decisions. In addition, performance politics also has a positive and significant effect on turnover intention, indicating that perceptions of unfairness and political practices in performance appraisal can increase employees’ intention to leave. Simultaneously, both independent variables have a significant effect on turnover intention, with a coefficient of determination of 23.4%. These findings emphasize the importance of managing employee personality traits and implementing a transparent and objective performance appraisal system to reduce turnover intention within the organization.

Abstract

Industri kreatif, khususnya sektor vendor event, menghadapi tantangan berupa ketidakpastian jadwal dan struktur kerja yang fleksibel sehingga keberhasilan organisasi sangat bergantung pada perilaku kewargaan organisasi (OCB). Penelitian ini bertujuan menganalisis pengaruh persepsi keadilan distributif dan dukungan sosial terhadap OCB pada karyawan Jitu Music Centre Sukabumi. Studi ini mengisi kekosongan studi terdahulu yang dominan berfokus pada sektor formal seperti perbankan, pendidikan, dan pemerintahan, dengan menguji hubungan kausal secara langsung dalam konteks kerja informal. Metode penelitian menggunakan pendekatan kuantitatif dengan teknik purposive sampling. Hasil penelitian menunjukkan bahwa keadilan distributif dan dukungan sosial berpengaruh signifikan terhadap OCB. Keadilan dalam pembagian tugas serta dukungan dari atasan maupun rekan kerja terbukti mendorong perilaku ekstra peran yang mendukung efektivitas organisasi. Penelitian ini memberikan kontribusi teoritis dengan memperluas kajian OCB ke sektor kreatif informal, serta kontribusi praktis bagi manajemen sumber daya manusia dalam membangun budaya kerja yang adil, suportif, dan kolaboratif untuk meningkatkan kinerja organisasi. Selain itu, penelitian ini memperkaya literatur dengan menyoroti peran OCB sebagai mekanisme adaptif dalam menghadapi ketidakpastian kerja. Implikasi hasil penelitian dapat dijadikan dasar bagi pengembangan kebijakan SDM yang lebih responsif terhadap kebutuhan sektor kreatif. Dengan demikian, studi ini tidak hanya relevan bagi akademisi, tetapi juga memberikan manfaat praktis bagi pelaku industri kreatif dalam meningkatkan daya saing organisasi.

Abstract

The creative industry, particularly the event vendor sector, faces challenges such as schedule uncertainty and flexible work structures, making organizational success highly dependent on Organizational Citizenship Behavior (OCB). This study aims to analyze the influence of distributive justice perception and social support on OCB among employees of Jitu Music Centre Sukabumi. It addresses a gap in previous studies that predominantly focused on formal sectors such as banking, education, and government, by directly examining causal relationships within the informal work context. The research employed a quantitative approach with purposive sampling techniques. Findings indicate that distributive justice and social support significantly affect OCB. Fair task distribution and support from supervisors and colleagues were proven to encourage extra-role behaviors that enhance organizational effectiveness. This study contributes theoretically by expanding OCB research into the informal creative sector and practically by providing insights for human resource management in fostering a fair, supportive, and collaborative work culture to improve organizational performance. In addition, this study enriches the literature by highlighting OCB as an adaptive mechanism in dealing with work uncertainty. The implications of the findings can serve as a foundation for developing HR policies that are more responsive to the needs of the creative sector. Thus, this research is not only relevant for academics but also offers practical benefits for creative industry practitioners in enhancing organizational competitiveness.

Abstract

Government projects have a significant impact on public welfare and economic development, particularly in developing countries such as Indonesia. Under the prevailing regulations, government project delivery systems are generally categorized into two types: Design–Bid–Build (DBB) and Design–Build (DB). Achieving and improving the performance of government projects is essential to ensure contractual compliance and to serve as a model of best practices and lessons learned. This study aims to analyze the factors influencing the performance of government projects under both DBB and DB systems through a comprehensive literature review of prior studies. By employing an exploratory qualitative approach, this research identifies key factors as the main variables that should be considered in measuring government project performance for both delivery methods. The findings can be used to develop a Government Project Performance model for DBB and DB systems by project stakeholders as well as by academics who intend to further refine and expand this model in future research.

Abstract

This study aims to determine the compressive strength and modulus of elasticity of concrete with the addition of Damdex variables to obtain the best composition. This research method is classified as quantitative research conducted at PT. Fresh Beton Indonesia Batching Plan BSD. In this study, research was conducted using two different concrete mixtures, namely 1 Pc: 2 S: 3 Gr and 1 Pc: 3 S: 2 Gr, each of which was supplemented with Damdex at concentrations of 0.0%, 0.2%, 0.4%, and 0.6%. According to the study's results, the highest compressive strength and modulus of elasticity were achieved in a concrete mixture of 1 Pc: 2 S: 3 Gr, with a variable addition of Damdex at 0.2%, resulting in a compressive strength of Fc 15.11 MPa and a modulus of elasticity of 18975.061 MPa. Meanwhile, the lowest compressive strength and modulus of elasticity results were obtained in the concrete mixture of 1 Pc: 2 S: 3 Gr with the variable addition of Damdex 0.6%, with a compressive strength of Fc 12.90 MPa and a modulus of elasticity of 17049.89 MPa. In the concrete mixture of 1 Pc: 3 S: 2 Gr, the compressive strength and modulus of elasticity were smaller compared to the concrete mixture of 1 Pc: 2 S: 3 Gr, with the highest results in the variable addition of Damdex 0.2%, with a compressive strength of Fc 9.89 MPa and a modulus of elasticity of 13846.477 MPa. Compressive strength and elastic modulus were measured at 28 days in accordance with SNI 1974:1990/2847 procedures. Among the tested mixtures, the 0.20% Damdex addition achieved the highest average compressive strength and elastic modulus. Within the tested conditions, 0.20% Damdex provided the best average performance; however, further work with larger samples and additional durability metrics is needed to confirm this trend.
