Abstract

Public-rented flats, which are intended for low-income society, have characteristics which are different from other type of public housing. Based on past literatures, there are 9 characteristics which are public-housing/residential unit’s specifications, supporting facilities, public facilities, surrounding facilities, social environment, household character, location, owner, and funding which are associated with the residents’ satisfaction towards public housing. Other than the issue of public-rented flats’ characteristics, some researches have also suggested changing the institutional and financial scheme of management unit of public-rented flats (MUPRF), especially the ones in DKI Jakarta Province. Therefore this initial research is conducted to identify the characteristic variables of public-rented flats that affect the choice of changing the institutional and financial scheme for the MUPRF. This research is a qualitative research using triangulation analysis based on 3 sources of data which are past literatures, regulations and interviews. According to the triangulation analysis the characteristics that affects the choice of changing the institutional and financial scheme for the MUPRF are public facilities, surrounding facilities, household character, and funding.

Abstract

Subsea gas pipeline projects are experiencing significant technical and managerial challenges across Engineering, Procurement, and Construction (EPC) phases. To address the challenges, effective risk management in the early project phases is essential to mitigating cascading failures that cause significant schedule delay and cost overrun. Therefore, this study aimed to apply the Fuzzy Bayesian Belief Networks (FBBNs) method to model risk assessment during EPC phases. The findings showed that FBBNs made it possible for a new way to evaluate risks, find interdependencies, and guess what would happen next, which created a strong framework for reducing risk. Based on probabilistic analysis as supported by expert elicitation, risks from the early phase of engineering and procurement showed high probabilities of occurrence, including Incompetent Personnel, Project Mismanagement, Unsupportive Stakeholder, Corruption, and Design Inaccuracies. A significant impact was also observed on Construction Rework, Material Quantity Increase, Construction Delay, and Cost Overrun. The results showed the importance of addressing systemic issues early in the EPC project lifecycle, emphasizing personnel competency, design accuracy, strategic and project management planning, procurement management, stakeholder management, and constructability preparation to reduce vulnerabilities. This integrated method aimed to enhance accuracy predictions by determining causal risk probability relationships in high-risk offshore environments of EPC subsea gas pipeline projects. Doi: 10.28991/CEJ-2025-011-03-013 Full Text: PDF

Abstract

The strategic program of the Republic of Indonesia's Government is stated in the National Medium-Term Development Plan (RPJMN) for 2020 – 2024.One of its targetisconstruction of eighteen (18) multipurpose dams. Pasir Kopo Dam is included in the RPJMN target and its expected to provide raw water supply, irrigation water, and increase the potential for electrical energy through Micro-Hydro Power Plant (PLTMH). However, the dam construction requires a huge project costs which can't be handled solely by State Budget (APBN). There is funding gap in State Budget for financing the dam construction, so another financing alternative is needed. Public Private Partnership (PPP)is an alternative financing scheme for dam construction. PPP is influenced by economic feasibility analysis and identification of influential project risks. The selection of an investment-worthy PPP Scheme in the Pasir Kopo Dam Development Project is expected to be mutually beneficial for all parties involved in the cooperation.

Abstract

This study investigates physical issues and proposed improvement solutions in the development of the business district in Kertajati Aerocity. A mixed-method approach was aplied, combining qualitative descriptive statistics with the quantitative Analytical Hierarchy Process (AHP). The findings reveal two key physical issues contributing to the investment weakness in the Kertajati Aerocity Business District: accessibility and public facilities. Among these, issues related to public facilities were identified as having a higher priority (eigenvalue 0.595) compared to accessibility issues (eigenvalue 0.405). The public facilities problem specifically refers to the absence of entertainment facilities in the business district. Meanwhile, the accessibility issue pertains to limited road network provision. Proposed solutions to address the lack of entertainment facilities include the construction of entertainment infrastructure and partnerships or collaborations with investors. For the accessibility issue, suggested improvements involve building new road networks, prioritizing road development, and fostering collaborative investment schemes.

Abstract

The construction of toll roads is a key government program aimed at enhancing public productivity and accelerating national economic growth. To ensure that toll road construction meets the desired quality, time, and cost objectives, the involvement of competent supervision consultants is essential. However, suboptimal performance of these consultants often leads to less-than-ideal project outcomes. This study aimed to analyse the performance evaluation indicators of supervision consultants and incorporate them into a comprehensive performance assessment rubric for supervision consultants in toll road construction projects. The research methodology combined literature review, questionnaire surveys, and expert interviews for data collection. Then, each indication is ranked and weighted using the Rank Order Centroid (ROC) and Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) approaches. The results showed that respondents and experts identified 18 important indicators grouped into three categories soft skills, technical skills, and project supervision which can be used in a validated performance assessment rubric for evaluating supervision consultants in toll road construction projects.

Abstract

Building projects with private ownerss have high level of payment issues (late payment, underpayment, or non-payment). The purpose of this study is to develop a risk-based contract management strategy to avoid late payment from private ownerss to contractors. The research data consisted of literature reviews, questionnaires, and qualitative risk data analyses. The risk analyses identified 10 highest risks as the dominant risk factors from 37 risk variables. The risk response to dominant risk variables was used as a strategy for developing a contract management system. Risks affecting late payment were largely due to contractual clause and contracting clients with less financial capacity due to lack of analysis in the pre-contract phase.

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.”
