Abstract

Perubahan iklim dan dinamika cuaca ekstrem menuntut ketersediaan sistem pemantauan cuaca yang akurat, berkelanjutan, dan mudah diakses. Sistem konvensional yang bergantung pada infrastruktur listrik dan operasional manual sering kali menghadapi keterbatasan di wilayah terpencil. Sebagai respons terhadap tantangan tersebut, dikembangkan alat pemantauan cuaca self-sustain berbasis Internet of Things (IoT) yang mampu menyediakan data atmosfer secara real-time melalui integrasi sensor otomatis dan sumber energi surya. Sistem menggunakan sensor DHT22, BMP280, BH1750, anemometer digital, dan rain sensor yang dihubungkan ke mikrokontroler ESP32 dan dikirim ke cloud platform (ThingSpeak dan Blynk) untuk visualisasi data daring. Pengujian dilakukan selama tujuh hari di lingkungan terbuka Kampus ITNY dengan interval pengambilan data setiap lima menit. Hasil menunjukkan akurasi pengukuran dalam batas ±5% dibandingkan data BMKG, efisiensi energi 84,7%, dan tingkat keberhasilan transmisi data 97,6%. Sistem mampu beroperasi mandiri hingga 78 jam tanpa sinar matahari, membuktikan efektivitas rancangan self-sustain berbasis energi terbarukan. Penelitian ini mendukung pengembangan sistem pemantauan cuaca yang efisien, hemat energi, dan berkelanjutan untuk mendukung mitigasi bencana dan perencanaan sumber daya berbasis data real-time.

Abstract

Indonesia sering mengalami bencana alam yang merusak infrastruktur, termasuk hunian. Korban bencana memerlukan hunian sementara yang aman dan nyaman, di mana hunian modular menjadi solusi karena fleksibel, cepat dipasang, dan dapat dioptimalkan menjadi semi permanen. Pemilihan material untuk hunian modular harus ringan, mudah didapat, dan tahan cuaca. Tujuan penelitian ini adalah untuk mengidentifikasi penggunaan material yang optimal untuk hunian modular sementara dengan menggunakan metode statistik ciri orde pertama. Data diperoleh dari 91 responden melalui pengamatan terhadap proyek hunian modular. Data tersebut dianalisis secara statistik untuk mengevaluasi rata-rata, simpangan baku, serta mengidentifikasi potensi anomali dalam penggunaan material pada struktur tiang penyangga, dinding, dan pondasi. Analisis material pada hunian modular sementara menunjukkan variasi signifikan. Material TP_BR pada tiang penyangga digunakan lebih dominan (rata-rata 2.83) dibandingkan TP_P (1.87), yang bisa menjadi anomali jika perbedaan melebihi deviasi standar. Pada dinding, AD_GG digunakan lebih sering (2.8) dibandingkan AD_PE (2.24) dan AD_S (2.45), yang juga bisa dianggap anomali jika tidak konsisten. Pada pondasi, SP_BT memiliki rata-rata 2.55, lebih tinggi dari SP_A (2.22), yang mungkin mencerminkan anomali

Abstract

The demand for fast, efficient, and adaptive emergency housing continues to increase, especially in disaster-prone areas and large-scale displacement situations. The determination of the design of Temporary Modular Shelter (TMS) so far still depends a lot on subjective considerations, so a more systematic and data-based approach is needed. This study develops and validates an Artificial Neural Network (ANN) model to identify the most suitable TMS design based on performance indicators and expert assessment. The approach was carried out through the Systematic Literature Review (SLR) stage, the determination of eight key design indicators, and assessment by 150 multidisciplinary respondents. The ANN model was built using a dense four-layer architecture with a total of 1,780 parameters and trained for 400 epochs using the TensorFlow and Keras libraries. The results showed a validation accuracy of 96% and a macro F1-score of 0,9146, indicating the stability and reliability of the model. Analysis of the contribution of features with the SHAP method revealed that the indicators of assembly methods, availability of human resources, and availability of local materials had the greatest influence on the classification results. This model has proven to be effective as a decision support system that is able to increase objectivity and efficiency in the TMS design process. Further development is suggested through integration into web-based digital platforms or mobile applications to support rapid and adaptive emergency response planning.

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

Flooding is a frequent natural disaster in Indonesia, especially in areas with low topography and high rainfall. The Telomoyo watershed in Kebumen Regency, with an area of 553.22 km², faces a high risk of flooding even though its water flow is controlled by the Sempor Reservoir. Geographical conditions, topography and high rainfall in the upstream area often cause inundation in the downstream area. This study modeled the flood potential in the Telomoyo watershed using HEC-RAS software, based on rainfall data and a Digital Elevation Model (DEM). The methodology includes hydrological analysis to determine peak discharge using the Nakayasu Synthetic Unit Hydrograph (HSS) method and hydraulic analysis to map flood-prone areas. The results showed that the combination of rainfall and topographic data resulted in accurate mapping of flood-prone areas. The peak discharge of the 25-year return period reached 986.177 m³/second, with inundation up to a depth of more than 3 meters in certain areas. Integration of satellite rainfall data from NASA's Giovanni with 2D hydraulics modelling based on HEC-RAS, which produced flood risk maps for the Telomoyo watershed with a high level of accuracy that was previously under-explored. The outcome of this research for flood management in the Telomoyo watershed is the provision of a scientific basis for more effective mitigation strategies, such as strengthening drainage infrastructure, and risk zone-based spatial planning. This information can be used as a basis for more effective flood mitigation planning and risk management in the Telomoyo watershed area.

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

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.
