Abstract

The vulnerability of simple houses in earthquake-prone areas, particularly those built independently with limitations of key structural elements, demonstrates the need for a measurable and efficient partial rehabilitation approach. Although the reinforcement of earthquake-resistant buildings has been widely studied, the analysis of partial rehabilitation costs separating the calculations on each major structural element is still relatively limited. This study aims to compile an analysis of partial rehabilitation costs on column, ground beam, and ring beam elements by referring to the Unit Price Analysis and the Bantul Regency Standard Unit Price for Materials and Services in 2024. The quantitative method was applied using technical data from the results of MBKM internship activities at the Bantul Regency BPBD, which included the dimensions of structural elements, ironing details, and concrete quality. The calculation of material requirements and costs is carried out separately on each element to obtain a more measurable estimate. The results of the study showed that the cost of rehabilitating columns, ground beams, and beam rings amounted to Rp 14.676.740,54 each, Rp 14.213.412,00, and Rp 13.009.214,44. These findings confirm that differences in dimensions, element functions, and reinforcement methods have a direct effect on the amount of cost. This research contributes in the form of an approach to partial rehabilitation cost analysis that is applicable as a basis for technical decision-making in the planning of simple house reinforcement in earthquake-prone areas.

Abstract

Formwork in construction projects has a high level of risk to worker safety due to heavy material handling, equipment use, and activities at height. This study will investigate potential hazards in formwork through Job Safety Analysis (JSA) and assess the effectiveness of risk control based on the Hierarchy of Control, which includes elimination, substitution, engineering control, administrative control, and the use of personal protective equipment (PPE). Data collection was executed via on site observations, evaluation of project K3 documentation, and conversations with safety officers, supervisors, and associated workers. The results of the analysis indicated that risk control was more applied to engineering control (55.1%), administrative control (20.4%), and the use of PPE (20.4%). Meanwhile, of substitution (4.08%) and elimination (0%) are still very low. This condition shows that the control with the highest level of effectiveness has not been maximized, so the potential risk of accidents remains high. The findings emphasize the value of implementing top-level controls from the planning and design stages of the project. The use of Hierarchy of Control-based Job Safety Analysis has proven to be a systematic approach in determining risk control priorities and improving occupational safety management. Thus, the results of this study provide strategic recommendations for construction projects in minimizing accidents and building a more effective safety culture.

Abstract

Hotel building maintenance in tourism-driven regions such as the Special Region of Yogyakarta is essential for maintaining service quality and building reliability. However, conventional assessment methods often depend on subjective expert judgment, which may be time-consuming and inconsistent. This study evaluates the performance of Support Vector Machine (SVM) combined with Principal Component Analysis (PCA) to classify hotel building maintenance levels in Yogyakarta into five categories. The dataset includes 175 samples and 11 variables covering architectural, structural, mechanical, electrical, outdoor space, and housekeeping aspects, with naturally imbalanced class distribution. Data were normalized using MinMaxScaler and reduced to nine principal components, explaining 93.41% of cumulative variance. Three SVM kernels polynomial, radial basis function (RBF), and sigmoid were tested using a 70:30 training–testing split with default scikit-learn hyperparameters. The sigmoid kernel produced the best performance, achieving 90.57% accuracy, 91.32% precision, 90.57% recall, and 90.53% F1-score, outperforming RBF and polynomial kernels. Stratified 5-Fold cross-validation showed an average accuracy of 81.71% ± 9.66%. The results indicate that PCA-SVM with a sigmoid kernel is effective for automated hotel building maintenance classification.

Abstract

Penjadwalan merupakan elemen fundamental dalam manajemen konstruksi karena menentukan efektivitas pengaturan waktu dan urutan pekerjaan, terutama pada pembangunan rumah tipe 36 yang memerlukan ketelitian dalam mengelola durasi dan ketergantungan aktivitas. Penelitian ini bertujuan menganalisis dan membandingkan hasil penentuan lintasan kritis antara metode Critical Path Method (CPM) dan Precedence Diagram Method (PDM) untuk memahami perbedaan struktur ketergantungan dan implikasinya terhadap efektivitas penjadwalan proyek berskala kecil. Metode penelitian menggunakan pendekatan kuantitatif dengan rancangan deskriptif-komparatif berdasarkan data aktivitas dan durasi pekerjaan yang diperoleh dari perencanaan proyek di BPBD Kabupaten Bantul, kemudian dianalisis melalui penyusunan jaringan kerja, perhitungan maju–mundur, dan identifikasi aktivitas kritis pada kedua metode. Hasil penelitian menunjukkan bahwa CPM dan PDM menghasilkan durasi total proyek yang sama, yaitu 70 hari, namun dengan konfigurasi lintasan kritis berbeda: CPM mengidentifikasi 15 aktivitas kritis (45,45%), sedangkan PDM mengidentifikasi 26 aktivitas kritis (78,79%). Perbedaan ini menunjukkan bahwa PDM lebih sensitif terhadap hubungan paralel, sedangkan CPM lebih sesuai untuk struktur kerja linear. Penelitian merekomendasikan penggunaan PDM pada proyek yang membutuhkan ketelitian tinggi dalam pemodelan ketergantungan aktivitas dan CPM sebagai alat pemetaan awal lintasan kritis.

Abstract

Post-disaster temporary shelters in Indonesia often generate significant construction waste because of their single-use nature. This study aims to map reusable and reconfigurable concepts as the foundation of Temporary Modular Shelter (TMS) material design and to analyse their contributions to environmental sustainability. A Systematic Literature Review (SLR) following the PRISMA 2020 protocol was conducted on peer-reviewed articles and indexed proceedings published between 2015 and 2025, retrieved from Scopus, ScienceDirect, and Google Scholar. Of 412 records initially identified, 87 peer-reviewed studies met the inclusion criteria. Thematic analysis was performed using NVivo 12 with a hybrid deductive–inductive coding approach. The findings show that reusable–reconfigurable principles are operationalised through modular systems and reversible dry connections that allow shelter components to be potentially reused or adapted for permanent housing construction. Five main material components were identified: frames, wall panels, roofs, flexible elements, and flooring/base modules. The approach is reported in the reviewed literature to support construction waste reduction, circular economy practices, lower embodied carbon, and improved resource efficiency, although the magnitude of these benefits varies with material type, transport distance, and the number of reuse cycles. This study contributes an integrative sustainability-based framework linking reusable–reconfigurable principles with post-disaster TMS material systems. Remaining challenges include module standardisation, local human resource capacity, comprehensive Life Cycle Cost analysis, and socio-economic integration. The framework provides a reference for policymakers, researchers, and practitioners developing adaptive and sustainable temporary housing in disaster-prone regions.

Abstract

Rumah Sampah Ringas Trengginas is a community-based organic waste management group in Baturetno, Banguntapan, Bantul, that produces eco enzyme from kitchen waste. Before this programme, fermentation was conducted manually without measurement instruments, systematic records, or standard operating procedures, so product quality varied between batches and fermentation failure was difficult to detect early. Unlike previous community service programmes that focused on production training, this programme developed a data-driven fermentation quality standardisation model for waste management communities. The programme involved four core partner members and surrounding residents, and was carried out in five stages are socialisation and needs assessment, device design and assembly, development of the recording and notification system, on-site installation and partner training, and evaluation. The device used an ESP32 microcontroller integrated with pH, TDS, NPK, and DS18B20 temperature sensors, TLS/SSL-encrypted MQTT data transmission, an early-warning buzzer, and web- and mobile-based interfaces. Success was evaluated through three instruments sensor accuracy testing against calibrated portable meters (ten paired measurements per parameter per batch), measurement of daily monitoring time before and after the intervention, and a partner competency checklist. The main outputs were an installed IoT monitoring device, a web- and mobile-based recording system, a copyright-registered production SOP, and an industrial design application. Preliminary testing of three batches showed a mean accuracy of 95% with pH of 3.5–3.7 and temperature of 28.5–29.0 °C under normal fermentation conditions; daily monitoring time fell from 60 to 18 minutes (70% efficiency); and all core members operated the system independently. The findings indicate that the system can support community-scale fermentation standardisation, although validation on a larger number of batches is still required.  Keywords: Eco enzyme; Internet of Things; Fermentation Monitoring; Organic Waste; Quality Standardization.
