Abstract

High accident risk in construction projects indicates that OHS documentation alone is insufficient without consistent on-site implementation of safe work procedures. Objective: This study evaluates the implementation of Occupational Health and Safety (OHS) based work procedures and analyzes their impact on the performance of the Construction Safety Management System (CSMS) in the Architectural Christian Center construction project, addressing the gap between administrative and operational compliance. Methodology: An evaluative design with combined descriptive quantitative and qualitative approaches was applied. Data were collected through questionnaires administered to project personnel, field observations, and reviews of OHS-related documents. Analysis compared on-site practices with applicable regulations and the CSMS theoretical framework, supported by interpretation of questionnaire and observation results to identify implementation gaps. Findings: Normatively, OHS-based work procedures meet CSMS documentation requirements; however, operational implementation remains ineffective. Work procedures and Job Safety Analysis (JSA) are still treated primarily as administrative instruments and are not consistently integrated into daily work execution methods. Worker compliance is uneven: PPE use shows relatively better adherence than compliance with work procedures and JSA, indicating that risk control is still oriented toward individual protection rather than optimized through administrative controls and engineering-based work methods. Additionally, positioning OHS personnel within the contractor’s internal organization may reduce the independence and effectiveness of safety supervision due to pressures related to time, cost, and progress targets. Implications: Improving CSMS performance requires stronger integration of work procedures and JSA into routine execution, more consistent enforcement of procedural compliance, and strengthened supervisory authority to reduce reliance on PPE. Originality: This study explicitly links OHS work procedure implementation to CSMS performance while highlighting the contractor-internal OHS organizational structure as a structural factor affecting enforcement effectiveness, and provides actionable recommendations to embed safety within engineering-based construction execution methods.

Abstract

The construction sector is one of the largest greenhouse gas contributors in the world. The use of raw materials as building materials is the main cause of carbon emissions in the construction industry. The use of steel materials has become very popular because it can be associated with a number of qualities, including its extraordinary durability, resistance to pressure, and flexibility. This is the main cause of steel materials being used massively in construction projects. If this continues for a long time, it will result in increasingly severe global warming. Therefore, a very detailed analysis and calculation are needed regarding the relationship between steel weight, carbon content, and structural strength so that, in addition to being structurally strong, it can be efficient in weight and very minimal in the carbon value released during the work process and the life of the building. Tekla Structures software is one of the software programs that can be used for the above analysis needs, the ultimate goal of which is to reduce carbon emissions. Three (3) different cross-section sizes have been examined using structural analysis, and calculations have been made on the carbon content that can be optimized for the material: H 400.400.13.2, 350.350.10.16, and 300.300.10.15. This study has successfully determined that the column with the size H 300.300.10.15 produces a carbon mass of 629,288.00 kg. (kg CO2e). With the smallest carbon content value and the carbon presentation in the material of 66.23%, the column cross-section with the size H 300.300.10.15 is recommended for use as a column structure cross-section

Abstract

Struktur baja memiliki rasio kekuatan terhadap berat yang tinggi, waktu pelaksanaan lebih cepat, dan tingkat presisi dimensi yang baik, sehingga sesuai diterapkan pada bangunan industri seperti pabrik PT. Komatsu New Assembly di Cibitung, Bekasi. Penelitian ini bertujuan untuk memodelkan dan menganalisis perilaku struktur atas baja terhadap beban gravitasi dan beban gempa menggunakan perangkat lunak ETABS, serta mengevaluasi apakah hasil perencanaan memenuhi persyaratan kekuatan, kestabilan, dan keamanan sesuai ketentuan SNI yang berlaku. Penelitian menggunakan metode deskriptif-analitis dengan pendekatan studi kasus pada struktur atas bangunan PT. Komatsu New Assembly. Data primer berupa gambar struktur dan data sekunder berupa spesifikasi material serta ketentuan pembebanan (SNI 1729:2015, SNI 1726:2019, SNI 2847:2019, SNI 7860:2020, dan SNI 1727:2013) dikumpulkan dan digunakan untuk membangun model tiga dimensi pada ETABS. Beban mati, beban hidup, dan beban gempa statik ekivalen diinput, kemudian struktur dianalisis untuk memperoleh gaya dalam yang digunakan dalam pemeriksaan kapasitas elemen dan perencanaan sambungan. Hasil analisis ETABS menghasilkan gaya geser dasar sebesar 1.306,48 kN pada arah X dan 1.248,88 kN pada arah Y. Nilai rasio PMM maksimum diperoleh sebesar 0,862 pada balok dan 0,138 pada kolom, keduanya berada di bawah batas 1,00. Sambungan balok-kolom, kolom-kolom, dan baseplate yang direncanakan menggunakan baut M16, pelat penyambung, dan las sudut memenuhi persyaratan kekuatan, dengan nilai interaction equation sebesar 0,061 pada sambungan balok-kolom kritis.
