Abstract

Penerapan gaya arsitektur industrialis yang mengekspos material raw seperti dak beton marak diaplikasikan pada hunian modern. Namun, ketiadaan elemen insulasi pada atap di kawasan iklim tropis pesisir berpotensi memicu anomali termal. Penelitian ini bertujuan untuk mengevaluasi dan mengkomparasi akumulasi beban pendinginan (cooling load) pada hunian dua lantai bergaya industrialis di Kabupaten Demak. Metode komputasi kuantitatif yang digunakan merujuk pada standar utilitas mekanikal ASHRAE dengan mengaplikasikan variabel Cooling Load Temperature Difference (CLTD). Analisis komparatif dilakukan antara ruang di lantai satu (terproteksi pelat lantai) dan lantai dua (terpapar atap dak beton secara langsung). Hasil perhitungan membuktikan terjadinya lonjakan beban termal yang sangat ekstrem pada lantai dua, yakni mencapai 9.984 BTU/h, melampaui secara signifikan beban lantai satu yang hanya sebesar 5.546 BTU/h. Diskrepansi absolut dengan lonjakan mencapai 80% ini mengonfirmasi bahwa atap beton ekspos bertindak sebagai konduktor panas masif yang memaksa eskalasi utilitas mekanikal secara drastis, dari kebutuhan awal tata udara berkapasitas 3/4 PK di lantai satu menjadi 1,5 PK di lantai dua. Penelitian ini menyimpulkan bahwa estetika arsitektur industrialis di wilayah pesisir wajib diintegrasikan dengan intervensi desain pasif, seperti penggunaan solar reflective coating atau roof garden, agar selaras dengan prinsip efisiensi energi bangunan berkelanjutan.

Abstract

This study aims to analyze the composition and cost efficiency of the construction project for the rehabilitation of the Wajak Subdistrict Office in Malang Regency. Cost management is a critical aspect of construction management as it relates to the effective and efficient use of resources. The data used in this study consists of secondary data from the Cost Estimate (RAB) and Unit Price Analysis (AHSP) documents for the 2022 project, which were reanalyzed in 2024. The research method employed is quantitative descriptive analysis using a percentage-based approach to determine the distribution of construction costs by type of work. The results of the study indicate that the total construction cost amounts to Rp199,826,534 with an uneven cost distribution. Retaining wall work constitutes the largest cost component with a contribution of 58.21%, followed by ceiling and roof work at 22.99%, while other works have relatively small contributions. The analysis results indicate that the dominance of costs in formwork work is influenced by the large volume of work and the high material requirements. Therefore, construction cost control needs to be focused on the work with the largest contribution so that cost efficiency can be optimally achieved.

Abstract

This study aims to evaluate the appropriateness of the Construction Safety Management System (SMKK) cost allocation in the Ngantang Sub-District Office Renovation Project, Malang Regency, against the provisions of Minister of PUPR Regulation No. 10 of 2021. The research method used is descriptive quantitative with a desk study approach to analyze the Engineer's Estimate (EE) documents of the project valued at IDR 199.732.000.00. Risk analysis results indicate the presence of "High" to "Extreme" hazard categories, particularly the risks of workers not using personal protective equipment (PPE), being struck by materials, and work areas not separated from public activities. Although the SMKK budget allocation of IDR 1.974.715.38 has been provided, the evaluation found that several components such as Work Protective Equipment (APK), PPE specifications, and the qualifications of OHS personnel are still not in compliance with regulatory standards and the risk levels of renovation work. This study recommends budget adjustments for technical protection items and competent supervision to ensure the effectiveness of risk control in the field.
