Abstract

Indonesia, situated on tectonic plate boundaries, is highly susceptible to earthquakes that cause significant damage to infrastructure and housing, particularly impacting low-income communities (LIC). This study evaluates the feasibility of providing Earthquake-Resistant Construction Houses (ERCH) through a Public-Private Partnership (PPP) scheme. Using qualitative and quantitative methods, the research examines technical, financial, and economic aspects of the PPP scheme, focusing on earthquake-resistant technologies and the involvement of government and business entities. Findings indicate that the PPP scheme effectively addresses challenges such as limited government budgets and land availability while promoting the construction of 10,000 special housing units for disaster-prone areas under Indonesia’s 2020–2024 Infrastructure Development Framework. Financial analysis shows a 25% Internal Rate of Return (IRR), a payback period of four years, and sustainable viability through private-sector participation and government guarantees. This study highlights the potential of PPP schemes to enhance disaster resilience, optimize resources, and provide sustainable housing solutions for vulnerable communities.

Abstract

Penelitian ini bertujuan untuk mengidentifikasi tingkat kematangan pengadaan berbasis keberlanjutan di PT United Tractors Tbk serta merumuskan strategi peningkatan yang tepat guna mendukung kinerja proses pengadaan barang dan jasa. Dalam penelitian ini digunakan pendekatan Sustainable Procurement Maturity Model (SPMM) sebagai kerangka untuk mengukur kematangan organisasi pengadaan dalam aspek keberlanjutan yang mencakup dimensi tata kelola, kapabilitas sumber daya manusia, proses, kepatuhan, serta kolaborasi dengan pemangku kepentingan. Pengumpulan data dilakukan melalui penyebaran kuesioner kepada pihak internal perusahaan yang terlibat secara langsung maupun tidak langsung dalam proses pengadaan. Analisis deskriptif kuantitatif digunakan untuk menggambarkan kondisi aktual tingkat kematangan pengadaan. Selanjutnya, analisis gap dilakukan untuk mengidentifikasi kesenjangan antara kondisi eksisting dengan kondisi ideal. Berdasarkan hasil tersebut, disusun strategi peningkatan menggunakan pendekatan benchmark best practices yang bertujuan untuk mendorong pengadaan yang lebih berkelanjutan dan selaras dengan target kinerja perusahaan. Hasil penelitian menunjukkan bahwa sebagian besar dimensi pengadaan berada pada level performing dan enabling, namun masih terdapat gap signifikan pada aspek kolaborasi dengan pemasok dan penguatan kebijakan internal. Oleh karena itu, strategi peningkatan difokuskan pada penguatan sistem tata kelola, pelatihan berkelanjutan, serta integrasi aspek keberlanjutan dalam evaluasi kinerja vendor.

Abstract

Indonesia’s transportation development in the next 5 years is projected to be accelerated to cope with the deficit and gap that had been built up over the last two decades. A study conducted by Bappenas and JICA for the National Mid-Term Development Plan (RPJMN) 2015-2019 projected the magnitude of investment needed for the transport sector in sums up to IDR 2,500 trillion or around IDR 500 trillion per year. The state budget (APBN) had been and will always be insufficient to finance the total needs for transport investment. The innovative financing in transport development becomes very urgent given the tight fiscal allocation of Indonesia’s state budget, which is not adequate in financing infrastructure development. Indonesia needs to be innovative to find other sources of funds to finance transportation development. There are two streams: (1) to create a financing scheme based on the state budget, such as a Performance-Based Annuity Scheme (PBAS), infrastructure bonds, and shariah-based bonds (Sukuk) and (2) to create a non-state budget financing scheme to utiize domestic funds that are available domestically. The aim of this paper is to explore the possibility of Shariah-Compliant financing as a financing option for Indonesia’s infrastructure development. The methodology consists of estimating the infrastructure funding requirement in Indonesia, an understanding of Shariah-Compliant instruments in the global context, and lessons learned from other countries who who have applied Shariah-Compliant instruments for their infrastructure projects.

Abstract

One of the primary goals listed in the Sustainable Development Goals (SDGs) is to “Achieve universal and equitable access to safe and affordable drinking water for all,” as stated in SDG 6.1. To obtain this goal, the Government of Indonesia has developed the 2020-2024 National Medium-Term Development Plan (RPJMN), which has set specific targets including achieving 100% access to decent drinking water, 15% access to safe drinking water, and establishing 10 million house connections. The Ministry of National Development Planning has established a goal of achieving 45% access to safe drinking water by 2030 as part of the SDGs. However, as per the World Health Organization (WHO), Indonesia is projected to attain a 30% level of access to safe drinking water by 2022, which falls short of the objective set for 2030. Therefore, this study aims to identify the stakeholders involved in achieving safe drinking water goals and the factors that affect the achievement of access to safe drinking water. The methods employed include interviews to identify and map stakeholders, Geometric Mean (GM) analysis to assess the level of influence and interest of stakeholders, and Interpretative Structural Modelling (ISM) to determine the influence level of each factor. The findings reveal that seven agencies are involved as stakeholders. The primary stakeholders in the "Manage Closely" quadrant include the Ministry of National Development Planning, the Ministry of Public Works and Housing, and the Local Government. Additionally, 23 factors were found to have an impact on the provision of safe drinking water. The ISM analysis indicated that the most influential factors were “Restrictions on authority related to regional autonomy and power sharing between institutions/ministries,” “The number of stakeholders involved,” and “Regulations and policies related to the procurement of safe drinking water supply.”

Abstract

Joint Operation (JO) construction companies in Indonesia face persistent challenges in technology transfer, including misalignment between advanced technologies and organizational capacities. Knowledge management has been proposed as a strategic solution, but its implementation remains underdeveloped. This study develops a framework to enhance technology transfer in JO construction projects through improved knowledge management practices. Utilizing a mixed-methods approach, the research combines a literature review with an analytical hierarchy process, fuzzy set theory, and a simple additive weighting method, supported by data from selected respondents involved in the Jakarta Mass Rapid Transit (MRT) project (CP201). Key findings identify knowledge acquisition, utilization, and sharing as critical processes, with sub-criteria such as clarity of roles and responsibilities and external collaboration emerging as pivotal. The SECI (Socialization, Externalization, Combination, and Internalization) model is applied to guide the development of actionable strategies for effective knowledge management. This study contributes a tailored framework for Indonesian JO construction companies, bridging gaps in technology transfer and advancing organizational capabilities. Practical recommendations are provided to improve knowledge integration and foster sustainable growth in infrastructure projects.

Abstract

Fiber optic network development is a strategic priority for expanding equitable internet access and supporting socio economic growth. Despite its importance, fiber optic projects often face implementation challenges that create stakeholder conflicts and expose projects to risks that may hinder success. Because fiber optic communication systems are widely used from local to international levels, their implementation demands not only technological readiness but also capable human resources. In this context, project managers are central to project outcomes, and selecting the right manager becomes essential, although the competencies required may differ across organizations and projects. Based on the literature, project managers’ hard competencies, soft competencies, and work experience are considered important factors related to project success. Work experience is also often viewed as a factor that can strengthen employee competencies. Accordingly, this study examines the effects of project managers’ hard and soft competencies on the success of fiber optic projects in Indonesia and tests whether work experience moderates these relationships.This study uses a quantitative survey approach and analyzes the data with Partial Least Squares. The findings show that work experience does not significantly affect the success of fiber optic projects in Indonesia and does not moderate the influence of either hard or soft competencies on project success. In contrast, hard competencies have a positive and significant effect on project success, while soft competencies show a positive but not significant effect. These results indicate that technical competence remains the most decisive factor in the success of fiber optic projects.

Abstract

The construction of toll roads requires supervision consultants capable of ensuring project quality, time, and cost performance, yet a structured and measurable assessment framework is lacking. This study develops a comprehensive performance assessment rubric for toll road supervision consultants using quantitative methods, including a literature review, a survey of 50 respondents, validation by six experts, and an application test by 12 evaluators. Data were analyzed using validity and reliability tests, Mann–Whitney U, AHP, TOPSIS, and ROC methods. The results identified 18 valid and reliable indicators grouped into three dimensions soft skills, technical skills, and project supervision. The most critical indicators were QA/QC (C=0.810), periodic reporting (0.782), and work volume management (0.711). Final dimension weights were 40% for technical skills, 30% for soft skills, and 30% for project supervision. Application of the rubric indicated consultants’ performance remained in the “Average” category, highlighting areas for measurable improvement in supervision practice.

Abstract

Vertical housing construction projects are inherently complex due to the involvement of multiple stakeholders, dense urban environments, and strict performance requirements related to cost, schedule, and quality. In government-led housing programs, these complexities increase project exposure to various construction risks that may undermine project outcomes if not properly managed. This study investigates the occurrence of construction risks and the distribution of stakeholder responsibility in government-led vertical housing projects in Indonesia. The study is based on a structured questionnaire administered to eight purposively selected key informants with direct experience in five public vertical housing projects, namely Kemayoran Athletes’ Vertical Housing, Pasar Rumput Vertical Housing, Vertical Housing Project in the New Capital City (IKN), Kedaung Baru Vertical Housing, and Muhammadiyah University Vertical Housing. Data were analyzed using a descriptive approach to identify dominant risk categories and stakeholder involvement patterns. The results indicate that scope-related risks, schedule delays, and cost overruns are the most frequently occurring risks, with responsibility predominantly associated with project owners, contractors, and supervisory entities. The findings also reveal that unclear role delineation and fragmented coordination contribute to the persistence of these risks across project stages. In conclusion, construction risks in vertical housing projects are closely linked to stakeholder responsibility structures and coordination practices. The study recommends strengthening risk-based coordination mechanisms and improving structured communication among key stakeholders to support more effective risk mitigation and enhance project performance in government-led vertical housing development.
