Abstract

Continuous infrastructure development in Indonesia has become one of the factors increasing the role of the construction sector in the Indonesian economy. The construction sector's contribution to the Indonesian economy ranks sixth, at 9.88 percent of Indonesia's Gross Domestic Product (GDP) in the first quarter of 2024. The relatively high injury rate on construction projects is associated with construction workers facing ever-changing work environments, typically involving heavy machinery, working at heights, noise, and other serious hazards. To address these unique safety challenges, organizations must be able to quickly adapt to changes by effectively capturing, storing, and disseminating new strategies that prevent injuries. This can be achieved through the role of a leadership style that can exemplify the importance of occupational health and safety (HSE) management. Previous research results show that leaders who can implement leadership styles effectively and decisively enable workers to follow HSE procedures properly, thereby improving employee performance. In this research, questionnaires will be distributed to 3 contractor organizations in medium to large construction projects in Malang City. The scope of work analyzed is the leadership style. This research is a type of quantitative research. The visionary leadership style has a very high level of application, being the most dominant, followed by charismatic, transformational, and transactional leadership styles, which are applied at high levels, indicating that these leadership styles do not have a full influence.

Abstract

Industri konstruksi memegang peranan krusial dalam pembangunan, namun tak dapat dimungkiri bahwa sektor ini turut menyumbang pada krisis lingkungan global melalui emisi CO2, limbah, dan konsumsi energi. Dalam konteks ini, konstruksi modular menawarkan potensi signifikan sebagai pendekatan berkelanjutan yang mampu mengatasi isu-isu tersebut, namun penerapannya di Indonesia masih belum masif. Penelitian ini bertujuan mengidentifikasi hambatan-hambatan dalam penerapan konstruksi modular di Indonesia dengan survei kuantitatif pada tiga perusahaan di wilayah Jakarta yang memiliki pengalaman dalam proyek modular. Data yang terkumpul kemudian dianalisis secara deskriptif untuk memberikan gambaran komprehensi mengenai hambatan utama yang menghambat implementasi pendekatan ini.

Abstract

Industri konstruksi sedang mengalami tantangan terkait dampak lingkungan, produktivitas, dan efisiensi. Teknologi konstruksi modular dapat menjadi alternatif untuk mengatasi tantangan-tantangan tersebut. Namun, keberhasilannya sangat bergantung pada pemahaman dan kesiapan perusahaan dalam manajemen risiko, terutama pada tahap desain dan perencanaan. Penelitian ini mengidentifikasi faktor risiko kritis dalam desain dan perencanaan pada proyek konstruksi modular melalui survei kuantitatif terhadap perusahaan konstruksi di Jakarta yang pernah menangani proyek konstruksi modular di Indonesia. Dengan menggunakan analisis Severity Index (SI) dan matriks risiko, studi ini menemukan lima faktor risiko kritis. Risiko kritis ini mencakup isu-isu seperti perubahan desain oleh klien, kesalahan toleransi, kesenjangan informasi, serta spesifikasi dan gambar desain yang tidak lengkap. Kata kunci: Konstruksi Modular, Manajemen Risiko, Severity Index

Abstract

Traffic congestion is a critical issue in Indonesia’s rapidly urbanizing areas, particularly in regions with high vehicle density such as East Java. To address this, the construction of the Djuanda Flyover in Sidoarjo was initiated as a National Strategic Project (PSN) to alleviate bottlenecks along the Surabaya–Sidoarjo corridor. This study aims to evaluate the probability of successful schedule acceleration in the Djuanda Flyover project using the Program Evaluation and Review Technique (PERT). The research employs a mixed-methods approach, combining quantitative data from weekly and monthly progress reports and PERT-based estimations, with qualitative inputs from expert questionnaires involving 22 project stakeholders, including the owner (BBPJN Jawa-Bali), supervisory consultants, and contractors (PT Wika-Nindya KSO). The analysis focused on the critical path of the project, applying three-point estimates (optimistic, most likely, pessimistic) for activity durations. The initial duration was estimated at 102 days. After applying PERT analysis, the duration was reduced to approximately 95.32 days. With this acceleration, the probability of meeting the 98-day target completion date is 64.8%. These findings reveal a significant risk of failure to meet the targeted acceleration, suggesting the need for enhanced risk mitigation strategies and improved scheduling reliability. The study contributes to infrastructure project management literature by demonstrating how PERT can quantify schedule uncertainty in strategic national infrastructure projects. Recommendations include refining expert judgment techniques, optimizing resource allocation, and implementing real-time performance monitoring to increase schedule confidence beyond 90%. This research may serve as a reference for future accelerated infrastructure projects under similar constraints.
