Abstract

Electricity project implemented by PT. PLN (Persero) UIP JBTB is a construction project of the High Voltage Transmission Network and High Voltage Cable Channel 150 kV Bangkalan. The construction will certainly stretch across various terrains that have various levels of risk in the construction process. In addition, the construction project of the High Voltage Transmission Network and High Voltage Cable Channel 150 kV is a very complex project so that each stage has different obstacles so that it has the potential to have high risks in its implementation. The risk management will be based on SNI 8615:2018 ISO 31000:2018 regarding Risk Management – Guidelines and SNI IEC/ISO 31010:2016 Risk Management – Risk Assessment Techniques. The risk management process begins with determining the scope, context and risk criteria and then proceeds with the risk assessment process which includes identification, analysis, risk evaluation and risk treatment. This research was conducted to identify the risks that arise in the High Voltage Transmission Network and High Voltage Cable Channel 150 kV Bangkalan transmission development project and formulate the most effective response for each extreme, very high and high risk category of the project. The risk analysis of the Transmission Network project was carried out using a qualitative method to obtain a risk category. At risk that have extreme, very high, and high categories are risks that cannot be tolerated and a quantitative analysis will be carried out using the Expected Monetary Value method as measured data. Furthermore, with the Decision Tree Analysis diagram, several alternative risk treatment branches will be obtained which will then be analyzed using the multiplication of the response success value with the cost impact value in order to obtain the most effective treatment option. The results of the risk treatment will be categorized into risk mitigation, transferring risk, and accepting risk and the result of residual risk will be known through testing the effectiveness of handling risk treatment. The highest risk in this study is the risk of less than optimal contractor performance which causes project completion to be late with risk treatment by means of the good/services provider process being selected through an auction process which is included in the list of selected providers. The recording the risk register is also carried out as a database in risk analysis research on the construction project of the 150 kV Bangkalan high voltage transmission network.

Abstract

PT XYZ merupakan perusahaan BUMN terkemuka di bidang konstruksi dan investasi, yang dalam beberapa tahun terakhir semakin banyak mengerjakan proyek-proyek dengan sistem rancang bangun khususnya di Divisi Gedung. Meskipun sistem ini diakui memiliki keunggulan dalam efisiensi waktu dan biaya dibandingkan sistem tradisional, implementasinya pada proyek-proyek PT XYZ tidak sepenuhnya menghasilkan kinerja biaya yang optimal. Berdasarkan data internal perusahaan, dari 21 proyek rancang bangun yang dilaksanakan pada tahun 2015–2023, sebanyak 43% mengalami pembengkakan biaya melebihi rencana awal. Dan trend dalam tiga tahun terakhir mengalami kenaikan jumlah proyek yang mengalami cost overrun. Berdasarkan hasil studi terhadap penelitian-penelitian sebelumnya, telah banyak dilakukan analisis faktor kinerja biaya proyek. Namun penelitian lebih lanjut penting untuk dilakukan analisis faktor kinerja biaya terhadap proyek rancang bangun khususnya dari sudut pandang kontraktor. Penelitian ini bertujuan untuk menganalisis faktor-faktor yang memengaruhi kinerja biaya proyek rancang bangun pada Divisi Gedung PT XYZ dan indikator-indikator pembentuknya. Penelitian dilakukan dengan metode kuantitatif menggunakan pendekatan Structural Equation Modeling Partial Least Squares (SEM-PLS) untuk menguji hubungan antar variabel laten yang ditentukan berdasarkan studi literatur dan hasil wawancara pakar. Data dikumpulkan dari 50 responden yang terdiri dari Project Manager, Site Engineer Manager, Site Commercial Manager, Site Operational Manager dan CARM yang memiliki pengalaman menangani proyek-proyek rancang bangun di PT XYZ. Hasil penelitian menunjukkan bahwa faktor financial dan contractor site management secara signifikan memengaruhi kinerja biaya proyek. Dan faktor contract secara tidak langsung memengaruhi kinerja biaya melalui mediasi faktor financial. Selain itu terdapat 4 indikator dominan pembentuk variabel dengan indikator perubahan lingkup kontrak pada faktor contract, indikator kontrol keuangan proyek yang buruk pada faktor financial, indikator komunikasi antar personil kurang baik pada faktor contractor site management dan indikator keterlambatan pengiriman material dan alat pada faktor resources. Temuan ini memberikan kontribusi penting dalam memahami struktur pengaruh antar faktor yang berperan dalam kinerja biaya proyek rancang bangun.

Abstract

The Indonesian oil and gas (O&G) industry, a strategic sector with vast offshore reserves, faces significant challenges due to the high failure rate of offshore construction projects. This profusion of offshore reserves has led to a rise in offshore O&G construction projects. However, the global failure rate of O&G offshore construction projects is alarming, with numerous projects experiencing delays, budget overruns, and quality issues that hinder the achievement of production targets.  Scope creep, a common phenomenon leading to delays, cost overruns, and quality issues, is a major contributor to these failures. To address this critical problem, this study aims to develop and validate measurement indicators for the causative factors of scope creep in Indonesian offshore O&G construction projects. A quantitative research approach was employed, combining literature review, pilot survey, and a main survey involving 104 practitioners in the industry. Data analysis using SmartPLS 3.0 confirmed the validity, reliability, and outer loading value of measurement indicators. Key findings reveal that risk consequences and awareness are crucial indicators of the risk factor, communication frequency is a key indicator for the communication factor, task overlap and knowledge diversity are identified as key indicators of complexity, construction method changes are a key contributor to the change factor, and accurate identification and structuring of decomposed project tasks are critical indicators for achieving desirable quality in Work Breakdown Structure development. These findings provide valuable insights for industry professionals to mitigate scope creep and improve the success of offshore O&G construction projects in Indonesia. Key words: Scope creep, Project Management, Project Scope Management, Offshore Construction Projects, Oil and Gas.

Abstract

The relocation of Indonesia's capital city from Jakarta to IKN (Capital City of the Archipelago) in Penajam Paser Utara is a monumental project covering an area of 2,876 hectares, which involves massive infrastructure development. To ensure the success of IKN development and development based on the principles in Law Number 3 of 2022 including equality, technological balance, resilience, sustainable development, livability, connectivity, and smart cities. BIM-GIS integration technology was key in managing the complexity of this project. With BIM-GIS integration, it supports digital transformation for more efficient and complete decision-making, including spatial variabels. This thesis aims to analyze the factors that influence the implementation of BIM-GIS integration technology in the early stages of IKN project development. Exploratory factor analysis methods are used to identify supporting factors that facilitate the successful implementation of BIM-GIS integration, as well as inhibiting factors that may hinder it. Questionnaires are used as a data collection tool from stakeholder respondents in IKN projects. Questionnaire data was analyzed using Exploratory Factor Analysis (EFA). The research results showed that there were 16 supporting factors with 4 component groups and 16 inhibiting factors with 6 component groups. Based on these results, strategic steps are proposed to contribute to the development of science and play a role in the successful relocation of Indonesia's capital city.

Abstract

Upstream oil and gas construction projects in South Sumatra face significant challenges related to execution delays due to geographic, technical, and social complexities. This study aims to analyze the factors causing Project Delays and formulate context-specific mitigation strategies. The method employed is Partial Least Squares - Structural Equation Modeling (PLS-SEM), involving 186 respondents consisting of project owners and industry practitioners. The results indicate that the Material variable has the most significant direct impact on Project Delays, followed by the Planning and Design variable. The Contractor factor acts as a mediator for the influence of the Labor, Financial and Economic, and External variables. Dominant delay-causing indicators include material shortages, inadequate site investigation, design mismatches, inaccurate price negotiations, and low safety awareness. The results of the Focus Group Discussion (FGD) support the quantitative findings by highlighting the importance of field data-based design validation, comprehensive site investigations, and the enhancement of local contractor capacity. The Focus Group Discussion also revealed that material unpreparedness and social conflicts arising from limited legal awareness and moral responsibility within local communities have further contributed to project delays. Based on these findings, the recommended strategies include conducting comprehensive site investigations based on subsurface, geotechnical, and social data, involving contractors from the early stages, implementing projects through digital approaches, and managing social risks through Corporate Social Responsibility (CSR) strategies and stakeholder engagement. This study offers practical contributions to improving the efficiency of upstream oil and gas projects, particularly in high-complexity regions such as South Sumatra.
