Abstract

Indonesia is a country that is very vulnerable to natural disasters, especially earthquakes, because of its position in the Pacific Ring of Fire region. Bantul Regency, Yogyakarta, is one of the earthquake-prone areas that requires disaster-resistant infrastructure, including disaster logistics warehouses as emergency logistics storage and distribution centers. This study aims to analyze the upper structure of the disaster logistics warehouse of BPBD Bantul Regency to be more optimal and earthquake-resistant using SAP2000 software. The secondary data used is technical data ranging from soil type, earthquake zone, dead load, live load, and earthquake load, which are analyzed according to SNI 1726:2019 and SNI 1729:2020 standards. The results showed that the steel profiles used were IWF 350x175x11x7 for the rafter, IWF 200x150x9x6 for front and rear regels, IWF 250x125x9x6 for side regels, and HB 300x300x18x10 for columns. It was found that the regel was unstable due to the failure to withstand lateral loads, but overall, the upper structure of the warehouse worked optimally according to the results of the check design and steel stress check.

Abstract

Indonesia is a disaster-prone country, one of which is landslides, which often occur in hilly areas with high rainfall. The impact damages the environment and infrastructure, especially buildings. For effective mitigation, a risk identification system based on artificial intelligence technology is needed. This study applies Genetic Algorithm Neural Network (GANN) in identifying buildings in landslide-prone areas. GANN was chosen for its ability to optimize network weights globally through selection, crossover, and mutation mechanisms, thus avoiding suboptimal local solutions. The dataset consists of 169 data with 12 structural features of the building. The model was configured with genetic parameters such as the number of generations 500, population size of 50, mutation rate of 10%, and the Stochastic Universal Sampling selection method. To Evaluate the performance of model created from dataset, we employed accuracy, precision, recall, and F1-score. The results showed an accuracy of 81% and an average F1-score of 0.82, with the best performance in the "Unsafe" class (recall 0.84). Although it still needs improvement, GANN has proven to have the potential as a decision support tool in data-driven landslide risk mitigation.

Abstract

Landslides are the biggest threat in the Kalirejo area. The dynamics of land movements in the mountains often cause cracks and potentially collapse. Landslides due to land fractures caused building damage. This study aimed to analyze the condition of a simple building on the influence of land fracture. The method used was conducting a field survey of existing buildings in the Kalirejo area. The data of the surveys were the percentage of building damage and building categorization. From the results of the analysis, the percentages of buildings in the safe category were 78 buildings or 54.17%, the buildings of the unsafe category were 51 buildings or 35.42%, and buildings with the unsafe category were 15 buildings out of 144 surveyed building with the percentage of 10.42%. Based on the results of the analysis using the Rapid Visual Screening (RVS) method, 15 buildings with unsafe conditions need to be relocated because they do not use the minimum structure required for simple buildings while the 51 buildings with unsafe conditions, repairs must be made to the structure according to the minimum requirements of simple buildings

Abstract

Kurangnya pemahaman sistematis mengenai faktor-faktor utama yang memengaruhi desain Temporary Modular Shelter (TMS) dalam berbagai konteks kebencanaan menjadi tantangan dalam pengembangan hunian darurat yang efektif. Penelitian ini bertujuan untuk mengidentifikasi karakteristik desain TMS yang paling sering dibahas dalam literatur ilmiah internasional. Metode yang digunakan adalah systematic literature review terhadap 120 artikel yang diperoleh dari ScienceDirect, SpringerLink, dan Google Scholar. Artikel yang memenuhi kriteria inklusi dianalisis menggunakan perangkat lunak NVivo 12 melalui pendekatan thematic coding untuk mengevaluasi tema dan indikator yang paling dominan. Hasil penelitian menunjukkan bahwa kemudahan akses ke lokasi bencana (188), tingkat keterampilan tenaga kerja (178), dan logistik material (175) merupakan tiga tema dengan frekuensi tertinggi. Sebaliknya, dimensi bangunan hanya muncul sebanyak 120 kali. Temuan ini menegaskan bahwa aspek sumber daya manusia dan logistik lebih krusial dibandingkan spesifikasi teknis bangunan dalam konteks perancangan TMS. Penelitian ini berkontribusi terhadap pengembangan desain hunian darurat yang lebih adaptif, efisien, dan berbasis bukti dalam bidang teknik sipil dan perencanaan tanggap bencana.

Abstract

Floods are a frequent natural disaster in Indonesia. Heavy rainfall and poor watershed management make the Cokroyasan River Basin (DAS), Bayan District, Purworejo Regency, especially susceptible. The purpose of this study is to analyze the flood inundation area and calculate the peak discharge in the Cokroyasan Watershed using satellite rainfall data and the Digital Elevation Model (DEM). The study calculates the highest water flow during floods using the Nakayasu Synthetic Unit Hydrograph (HSS) method and examines the water flow with HEC-RAS and ArcGIS to create maps showing areas that could flood. The results showed that, using the Log Pearson Type III distribution, the design rainfall for a 25-year return period with a flow coefficient of 0.288 was 117.6711 mm. The maximum flood discharge, as determined by the Nakayasu HSS, was 1684.028 m³/second. Hydraulic analysis was able to map the region of floods based on land cover, covering 16,200 km² in total. 4,961 km² were covered the low flood depth category (0–1 m), 3,175 km² the medium inundation (1–3 m), and 8,061 km² the high inundation (>3 m). The results of the simulation might lead to a more effective approach for managing and reducing the danger of flooding.

Abstract

The Mukti Jaya Waste Management Group faced irregularities in eco enzyme production, resulting in low product quality and inefficiency. This community engagement aimed to enhance the group's technical and managerial capacity through the implementation of Standard Operating Procedures (SOPs). The methods included initial observation, participatory SOP development, hands-on technical training, and implementation mentoring. Results showed an increase in production volume from 12 to 20 liters per batch, a 40% improvement in time efficiency, and a rise in active member participation from 44.4% to 84.4%. Understanding of standardized procedures also improved from a score of 2.7 to 4.4. Evaluations using questionnaires and field observations confirmed enhanced technical and organizational capabilities. Additional impacts included the adoption of production and financial recording systems, the development of a collective work culture, and increased environmental awareness. SOPs proved to be not only a technical guide but also a community empowerment tool promoting efficiency, self-reliance, and sustainability in organic waste management.

Abstract

The priority classification of road maintenance is an important issue in regional infrastructure management. This study developed a classification model based on Artificial Neural Network (ANN) to determine the priority of district road maintenance automatically based on actual condition data. The data covered 141 road sections, reduced from 15 to 9 main variables using Principal Component Analysis (PCA), and normalized with the Min-Max Scaler. The ANN model consists of 10 input neurons, 30 hidden neurons, and 5 priority class outputs. The data is divided in a 55-15-35 ratio for training, validation, and testing. The model produces 92% accuracy, 91.7% accuracy, 90.4% recall, and 90.9% F1-score. These findings demonstrate the reliability of ANN in multi-class classifications to support more efficient road maintenance decision-making. The novelty lies in the integration of actual field data, multi-criteria classification, and the application of ANN in the context of complex and underexplored district roads in the literature.

Abstract

The construction sector is one of the largest consumers of material resources, with reinforcement bars (rebar) contributing significantly to project costs. However, standard cutting practices often generate leftover steel, typically regarded as waste, despite its potential for reuse. This study aims to evaluate the efficiency of reusing rebar waste in the structural components columns, beams, and slabs of a two-story boarding house project in Bantul, Indonesia. A quantitative case study method was applied, analyzing planned versus actual steel usage, and calculating the waste percentage compared to the 5% standard from Indonesia’s AHSP. Field data, including drawings, BoQ, and technical reports, were used to measure actual rebar waste and its financial impact. Results show actual waste levels of 2.17% for columns, 2.55% for beams, and 1.21% for slabs significantly lower than the 5% benchmark. This translates into a cost saving of Rp11,393,643.78 for a medium-scale project. These findings confirm that precise planning and reuse of steel offcuts can minimize waste and promote sustainable construction practices. It is recommended that future projects adopt material reuse strategies and integrate digital tools such as BIM to enhance real-time material tracking and cutting optimization.
