Abstract

Tujuan dibangun jalan layang non tol (JLNT) Kampung Melayu-Tanah Abang sebagai upaya untuk mengatasi permasalahan kemacetan lalu lintas terutama pada jalan eksisting di kawasan perkotaan yang memiliki lahan terbatas.JLNT ini diharapkan memberikan aksesibilitas bagi lalu lintas menerus (trough traffic) yang melintasi ruas jalan ini sehingga diharapkan akan mempersingkat waktu tempuh perjalanan dari Casablanca menuju Tanah Abang. Namun perlu dikaji bagaimana efektifitas pemanfaatan JLNT tersebut terhadap pemanfaatan serta perilaku lalu lintas setelah dibangunnya jalan laying non tol tersebut.Penelitian ini bertujuan untuk mengetahui karakteristik distribusi pergerakan arus lalu lintas kendaraan yang menggunakan jalan layang non tol dan jalan non JLNT berdasarkan penempatan on/off ramp jalan layang non tol Tanah Abang – Kampung Melayu, membandingkan perilaku arus lalu lintas dan mengetahui kinerja pelayanan operasional dari jalan layang non tol Tanah Abang – Kampung Melayu. Analisis kinerja pelayanan jalan dengan menggunakan metode Highway Capacity Manual untuk jalan bebas hambatan.Dari hasil analisis, pengaruh pembangunan jalan layang non tol terhadap perilaku lalu lintas sebelum adanya jalan layang untuk arus kendaraan dari Fly over Tebet menuju Cideng menunjukkan bahwa waktu tempuh kendaraan yang melalui jalan arteri (tidak melalui JLNT) menjadi lebih lama daripada setelah dibangunnya JLNT. Namun untuk waktu tempuh apabila melalui JLNT menghasilkan waktu tempuh yang lebih singkat di sepanjang ruas JLNT namun menghasilkan waktu tunda yang lama saat arus menuju off ramp. Kinerja ruas JLNT Kampung Melayu – Tanah Abang apabila ditinjau dari tingkat pelayanan (LOS) menunjukkan kategori A. Namun harus juga didukung oleh oleh kinerja ruas jalan eksisiting dimana terjadi penggabungan arus lalu lintas dari JLNT dan jalan non JLNT sehingga tidak menimbulkan kemacetan.Kata kunci : JLNT, kinerja pelayanan, lalu lintas menerus, kapasitas

Abstract

Environmental, economic, and social factors are three critical dimensions that influence sustainable construction. Nevertheless, stakeholders in the construction sector remain insufficiently cognizant of the social dimension of sustainability. This study aims to elucidate the elements associated with the social dimension of sustainability and to identify factors deemed significant by stakeholders in the construction industry. This study employed a quantitative research methodology. A questionnaire was developed based on a review of pertinent literature and formed using a Likert scale. The questionnaire was subsequently sent to stakeholders in the construction industry, and the findings were evaluated utilizing the Relative Importance Index (RII). The findings indicate that three critical variables in social sustainability pertain to internal project stakeholders: workplace safety and health, stakeholder interaction, and worker training and education. These three elements are the essential components of social sustainability. Factors related to external stakeholders, such as the community around the project site, remain a secondary concern for construction industry players today.

Abstract

Introduction: The construction industry is widely recognized as one of the sectors with significant mental health challenges. Many studies revealed that mental health problems such as depression, burnout, and sleep difficulty are more common in the construction industry compared to other industries. The causes may include high risk environment, long working hours, job insecurity, and machoism culture. On the other hand, the issue of mental health in the Indonesian construction sector is still not widely understood. Hence, this study investigates the key context-specific factors that influence the mental health of construction workers. Method: A mixed-method approach was employed, consisting of an integrative literature review (ILR) and exploratory factor analysis (EFA). The ILR identified twenty-three context-specific mental health factors, subsequently used as input in the questionnaire survey. The questionnaire consists of demographic characteristics and measurement of mental health factors using a six-point Likert scale. The survey was distributed to construction workers in Indonesia, each with a minimum of two years of work experience. The collected data were analyzed using EFA. Result: This study found five key groups of context-specific factors: workplace, work pressure, role, gender inequality, and psychosocial factors. These factors are found to be deeply interconnected, often exacerbating one another. The study underscores the complexity of mental health issues in this high-pressure, high-risk industry. The results suggest that addressing these challenges requires a multifaceted approach to better understand and alleviate the stress experienced by construction workers. Conclusion: This study presents five mental health determinants among construction workers in Indonesia. The findings can form the basis for further research and the formulation of work policies that are more responsive to local conditions.

Abstract

The execution of construction projects involves many parties, one of which is subcontractors. In general, subcontractors can be divided into three types, namely domestic subcontractors, nominated subcontractors, and named subcontractors. Many studies have been carried out regarding the first two types of subcontractors, but studies related to named subcontractors are scarce. In contrast to nominated subcontractors, named subcontractors are selected by the main contractor based on a list of subcontractor names provided by the employer. This research aims to identify the criteria in selecting named subcontractors by the main contractor. This research applies a qualitative method approach with integrative literature review and interview techniques. The results show the company's experience, financial capabilities, technical capabilities, resource factors, and offer price factors as important selection criteria. This research contributes to the body of knowledge considering that there are still few studies on named subcontractors, especially regarding its selection criteria by the main contractor.

Abstract

Many prior studies focused on construction workers' perceptions of safety compliance, but little or no research has been undertaken to investigate the relationship between construction project sacrifice and safety compliance. Construction project sacrifice – known as ‘tumbal proyek’ in the Indonesian Language is a socio-cultural phenomenon that still exists in Indonesian society. This research examines the perceptions of construction workers regarding project sacrifice and their relationship to workers’ compliance with construction safety management. A mixed-method approach was employed, which consisted of an integrative literature review and questionnaire surveys. In total, there were 102 valid survey responses, which were analysed using Structural Equation Modelling-Generalised Structured Component Analysis (SEM-GSCA). The analysis demonstrates a positive relationship between workers’ perceptions of project sacrifice and safety compliance. This study adds by offering empirical data on the phenomenon of project sacrifice and how workers' perceptions of it can influence the construction safety compliance in Indonesia. Although this is a context-specific study, the findings can serve as a reference for future research to enhance the safety climate in construction projects.
