Abstract

The high rate of work accidents in construction projects in Indonesia shows that the implementation of occupational safety is not optimal, even though it has been required by regulations. The Occupational Safety and Health Management System (SMK3) is an important instrument for creating a safe work environment, increasing productivity, and reducing the risk of accidents. This study aims to find out the overview of the implementation of SMK3, the rate of work accidents, and labor productivity in the Bawela Stadium Construction Project in Sorong City, as well as to analyze the influence between these variables directly and indirectly. The research method uses a quantitative approach with a verifiable method. The sample in this study was 100 construction workers who were selected through a simple random sampling technique. Data were collected using a Likert scale questionnaire and analyzed using the Structural Equation Modeling–Partial Least Square (SEM-PLS) method. The results showed that the implementation of SMK3 in general was in the "adequate" category (score 3.40), the rate of work accidents was in the "adequate" category (score 2.46), and labor productivity was also in the "adequate" category (score 3.39). The implementation of SMK3 has a significant negative effect on the rate of work accidents and has a significant positive effect on labor productivity. In addition, the rate of work accidents has been shown to have a negative influence on labor productivity. Indirectly, SMK3 affects productivity through reducing the rate of work accidents. These findings affirm the importance of strengthening the occupational safety system through leadership, planning, and a culture of OSH to support the success of construction projects.

Abstract

Penelitian ini bertujuan untuk menganalisis dampak pemadatan tanah menggunakan vibro roller terhadap potensi keretakan struktur bangunan yang berada di sekitar area kerja. Studi ini menggunakan pendekatan kuantitatif melalui simulasi numerik berbasis finite element menggunakan perangkat lunak Plaxis 2D untuk memodelkan penurunan dan distribusi tekanan tanah akibat getaran. Hasil simulasi menunjukkan bahwa pada jarak 0,5 meter dari bangunan terjadi penurunan sebesar 2,2 cm dengan tekanan tanah 153,2 kN/m²; pada jarak 5 meter penurunan 0,97 cm (140,6 kN/m²); jarak 10 meter 0,32 cm (137,0 kN/m²); dan jarak 15 meter 0,29 cm (135,5 kN/m²). Secara teknis, nilai penurunan pada jarak 0,5 meter masih berada di bawah batas toleransi SNI 8460:2017 sebesar 2,5 cm, namun peningkatan tekanan tanah menunjukkan potensi risiko terhadap struktur tertentu dengan kondisi fondasi sensitif. Penelitian ini berkontribusi dalam memberikan batas aman operasional pemadatan getaran di area konstruksi padat, dengan rekomendasi jarak minimal 5 meter untuk mengurangi dampak deformasi dan menjaga keselamatan struktur di sekitarnya   This study aims to analyze the impact of soil compaction using a vibro roller on the potential for cracking in building structures around the work area. This study uses a quantitative approach through finite element-based numerical simulations using Plaxis 2D software to model the settlement and distribution of soil pressure due to vibration. The simulation results show that at a distance of 0.5 meters from the building, there is a settlement of 2.2 cm with a soil pressure of 153.2 kN/m²; at a distance of 5 meters, a settlement of 0.97 cm (140.6 kN/m²); a distance of 10 meters, 0.32 cm (137.0 kN/m²); and a distance of 15 meters, 0.29 cm (135.5 kN/m²). Technically, the settlement value at a distance of 0.5 meters is still below the tolerance limit of SNI 8460:2017 of 2.5 cm, but the increase in soil pressure indicates a potential risk to certain structures with sensitive foundation conditions. This research contributes to providing a safe operational limit for vibration compaction in dense construction areas, with a recommended minimum distance of 5 meters to reduce the impact of deformation and maintain the safety of surrounding structures.

Abstract

ermasalahan kerusakan bangunan sekolah memberikan dampak luas, tidak hanya pada aspek fisik dan kenyamanan proses belajar mengajar, tetapi juga pada kebutuhan biaya rehabilitasi yang cukup besar. Penelitian ini bertujuan menganalisis pengaruh usia bangunan, perawatan gedung, dan penggunaan ruang kelas terhadap tingkat kerusakan bangunan, serta mengidentifikasi hubungan antara tingkat kerusakan dan biaya rehabilitasi pada 12 SMK Negeri dan Swasta di Kota Cirebon. Metode penelitian menggunakan pendekatan kuantitatif dengan analisis verifikatif berbantuan SPSS dan melibatkan 60 responden. Hasil penelitian menunjukkan bahwa usia bangunan dan perawatan gedung berpengaruh positif dan signifikan terhadap tingkat kerusakan ruang kelas, sedangkan penggunaan ruang kelas tidak memberikan pengaruh signifikan. Perawatan gedung menjadi variabel yang memiliki kontribusi pengaruh terbesar (35,7%), diikuti usia bangunan (34%), dan penggunaan ruang kelas (27,1%). Secara simultan, ketiga variabel tersebut terbukti berpengaruh signifikan terhadap tingkat kerusakan. Rata-rata tingkat kerusakan ruang kelas sebesar 36,55%, dengan rentang kerusakan 13,30% hingga 50,21%, dan rata-rata kebutuhan biaya rehabilitasi mencapai Rp107.385.050,22. Analisis korelasi menunjukkan hubungan sangat kuat antara tingkat kerusakan bangunan dan biaya rehabilitasi (r = 0,981), yang mengindikasikan bahwa semakin tinggi tingkat kerusakan, semakin besar biaya rehabilitasi yang diperlukan.   The problem of school building damage has a broad impact, not only on the physical aspects and comfort of the teaching and learning process, but also on the need for significant rehabilitation costs. This study aims to analyze the influence of building age, building maintenance, and classroom use on the level of building damage, as well as identify the relationship between the level of damage and rehabilitation costs in 12 public and private vocational schools in Cirebon City. The research method uses a quantitative approach with verification analysis assisted by SPSS and involving 60 respondents. The results show that building age and building maintenance have a positive and significant effect on the level of classroom damage, while classroom use does not have a significant effect. Building maintenance is the variable with the largest contribution (35.7%), followed by building age (34%), and classroom use (27.1%). Simultaneously, these three variables are proven to have a significant effect on the level of damage. The average level of classroom damage is 36.55%, with a range of damage from 13.30% to 50.21%, and the average rehabilitation cost reaches Rp107,385,050.22. Correlation analysis shows a very strong relationship between the level of building damage and rehabilitation costs (r = 0.981), which indicates that the higher the level of damage, the greater the rehabilitation costs required.

Abstract

Occupational Safety and Health (OSH) is a crucial aspect in construction projects, which are characterized by a high risk of workplace accidents. Improving OSH performance requires effective implementation of the Occupational Safety and Health Management System (OSHMS) as well as continuous control mechanisms. This study aims to analyze the effect of OSHMS implementation and control on OSH performance in construction projects. A quantitative approach was employed using a survey method by distributing questionnaires to respondents directly involved in construction project activities. The collected data were analyzed using the Partial Least Squares–Structural Equation Modeling (PLS-SEM) method. The results indicate that OSHMS implementation has a positive and significant effect on OSH performance. In addition, OSHMS control also has a positive and significant effect on OSH performance, although its influence is lower than that of OSHMS implementation. These findings suggest that the implementation and control of OSHMS are complementary aspects in improving OSH performance in construction projects.

Abstract

The implementation of Simple Healthy Instant Houses (RISHA) as a temporary or permanent housing solution after an earthquake has become a strategic choice for the Indonesian government. RISHA is designed to be built quickly, affordably, and earthquake-resistant. However, in its implementation, there are various challenges that hinder the effectiveness and efficiency of the implementation of this system. The purpose of this study is to identify and evaluate the main obstacles in the implementation of RISHA buildings in post-earthquake rehabilitation projects, including technical, social, and institutional aspects. This study uses a qualitative method with a case study approach focused on the earthquake-affected area in Cianjur Regency. The results of the study indicate that the main challenges include limited understanding of the local community and workforce regarding the RISHA modular system, the availability of materials and structural components at the disaster site, limited training time, and lack of coordination between stakeholders. In addition, the cultural and architectural preferences of the local community also affect the level of acceptance of the RISHA building model. Thus, a more comprehensive and participatory approach is needed in the implementation of RISHA in order to increase its effectiveness as a sustainable post-disaster solution.

Abstract

Construction projects in DIY have high complexity because they are located in disaster-prone areas such as earthquakes, floods, and landslides, so they require structured risk management. This research aims to analyze the influence of cost, quality, time, and accident risk identification on disaster risk management of construction projects. The research employed a quantitative approach by distributing questionnaires to 30 respondents consist of contractors, consultants, and project supervisors. Data were analyzed using statistical test multiple linear regression to examine the influence of each aspect on disaster risk management. The findings indicate that cost risk identification has a significant effect on risk management effectiveness, particularly in preventing budget overruns caused by external conditions such as material inflation and supply uncertainty. The quality aspect contributes substantially to improving construction resilience against disasters, in line with the application of quality standards based on SNI and ISO. The time aspect shows a clear influence on successful risk mitigation, as project delays increase vulnerability to disaster impacts. Meanwhile, accident risk identification is strongly related to the contractors’ readiness in implementing occupational health and safety (OHS) procedures to reduce potential human and material losses. Overall, this study emphasizes the importance of integrating risk identification into the construction project management system in the Special Region of Yogyakarta Province. The findings provide practical implications for contractors, local governments, and other stakeholders in developing adaptive, measurable, and responsive risk management strategies in disaster-prone regions

Abstract

Banjir di Kota Bima yang dipicu oleh degradasi Daerah Aliran Sungai (DAS) dan lemahnya tata kelola mitigasi mendorong perlunya strategi terpadu yang mengintegrasikan pendekatan struktural dan non-struktural. Penelitian ini bertujuan untuk merumuskan strategi manajemen konstruksi yang efektif guna memitigasi banjir di DAS Kota Bima, dengan mengidentifikasi faktor penghambat koordinasi stakeholder serta mengembangkan model evaluasi keberlanjutan. Metode penelitian menggunakan pendekatan mixed-method explanatory sequential, yang mengkombinasikan analisis kuantitatif melalui survei terhadap 65 responden dari pemerintah, kontraktor, masyarakat, dan akademisi, dengan analisis kualitatif melalui wawancara mendalam dan FGD. Data dianalisis secara statistik dengan regresi linier berganda dan secara tematik untuk data kualitatif. Hasil penelitian membuktikan bahwa strategi manajemen konstruksi, penerapan teknologi BIM/GIS, integrasi mitigasi struktural-non-struktural, dan manajemen risiko berpengaruh signifikan dan positif terhadap efektivitas mitigasi banjir (R² = 0,967–0,996). Namun, faktor ego sektoral dan disparitas informasi menjadi penghambat utama koordinasi. Simpulan penelitian menegaskan bahwa keefektifan mitigasi banjir memerlukan integrasi holistik antara aspek teknis, teknologi, dan sosial-kelembagaan melalui kerangka manajemen konstruksi yang adaptif dan kolaboratif. Implikasinya, pemerintah perlu menerapkan kebijakan yang mewajibkan penggunaan BIM, membentuk forum kolaborasi multi-stakeholder, dan merevisi peraturan tata ruang berbasis risiko perubahan iklim.

Abstract

Rapid urbanization has led to an increased demand for land, often at the expense of the environment. In response, rain gardens have emerged as a popular and sustainable solution for managing stormwater. This study focuses on evaluating how rain gardens in Kota Baru Parahyangan (KBP), Bandung, contribute to improving community satisfaction and enhancing environmental quality.Using a descriptive qualitative approach, the research gathered data through in-depth interviews, observations, and documentation. The findings reveal that rain gardens in KBP effectively manage stormwater runoff, reduce flood risks, and improve air quality. Beyond these benefits, they also enhance biodiversity, beautify the surroundings, and support efforts toward achieving carbon neutrality, the environmental impact assessment (AMDAL) data for the KBP area indicates a reduction of 1°C in the local temperature. The community has expressed high satisfaction with the presence of rain gardens, recognizing their significant environmental benefits and positive impact on quality of life. However, the study also highlights challenges, such as the need for more regular maintenance. Overall, the adoption of rain gardens in KBP is a significant step toward building a sustainable urban environment. Integrating rain gardens into urban planning is strongly recommended to improve the quality of life in cities. The study also suggests expanding this initiative to other areas and emphasizes the importance of involving the community in planning and managing rain gardens to ensure their long-term success.
