Abstract

Bangunan cagar budaya merupakan bangunan yang butuh perlakuan khusus agar bangunan tersebut tidak kehilangan nilai fungsi dan aspek keselamatan konstruksinya. Seiring waktu bangunan cagar budaya mengalami perubahan fungsi, namun kerap kali perubahan fungsi pada bangunan tersebut tidak memperhatikan aspek keselamatan konstruksi. Penelitian ini bertujuan untuk mengidentifikasi karakteristik bangunan cagar budaya dari aspek keselamatan konstruksi serta pengaruh perubahan fungsi bangunan terhadap penambahan perkuatan dan perubahan nilai lahan berdasarkan NJOP (Nilai Jual Objek Pajak). Metode penelitian  deskriptif kuantitatif dari hasil observasi visual dilakukan untuk mengasses sesuai enam kategori kerusakan. Kategori kerusakan dikelompokkan menjadi tiga kondisi, yaitu baik, sedang, dan buruk. Analisis keamanan bangunan diambil berdasarkan kondisi struktur dan perkuatan pada bangunan yang dibagi menjadi tiga kondisi, aman (kategori kerusakan 0 – II dengan perkuatan), sedang (kategori kerusakan I – II tanpa perkuatan), dan rawan (kategori kerusakan III – V tanpa perkuatan). Hasil penelitian menunjukkan bahwa 81 dari 125 bangunan berubah fungsi. Dari 81 bangunan yang berubah fungsi, terdapat 23% bangunan yang diperkuat dan 77% bangunan yang tidak diperkuat. Sedangkan pada 44 bangunan yang tidak berubah fungsi, terdapat 20% bangunan yang diperkuat dan 80% bangunan yang tidak diperkuat. Jalan Kepodang merupakan daerah dengan kenaikan nilai lahan tertinggi yaitu 317% dengan 63% bangunan di jalan tersebut mengalami perubahan fungsi. Hal ini membuktikan bahwa perubahan fungsi bangunan berpengaruh terhadap kenaikan nilai lahan pada Kawasan Kota Lama Semarang

Abstract

Drought is one of the impacts of climate change, which affects agriculture's productivity and, eventually, farmers in Afghanistan. Afghanistan has a typical inland continental climate with considerable temperature and precipitation variation between seasons. A considerable part of Arabmazari's village relies on irrigation for agriculture; however, with the low precipitation, temperature rise, and surface and groundwater depletion, farmers experiences drought. The objective of the research is to explore the vulnerability and coping capacity of the farmers of Arabmazari village to drought. The research considers a non-probability purposive sampling method. The data was collected from 3 members of the Ministries through interviews and from around 30 farmers through FGD and questionnaires. The research adopts descriptive and correlational statistics to assist with the qualitative and quantitative nature of the study. The research finds that farmers are generally highly vulnerable to drought impacts. With the government's lack of facilities, financial capacity, and absence of mitigation and preparatory measures, farmers are forced to rely on their own, often ancient, methods to plan and survive drought. Some coping strategies for crops and livestock included cultivating drought-resistant crops, changing cropping patterns, practicing crop rotation, soil treatment, and providing supplementary feeds for animals. Non-farm coping strategies were selling/pledging assets, migration, seeking employment elsewhere, dropping out of school, and seeking humanitarian aid. The government intervention was only through drought relief, which was ineffective in the long run. It is recommended that the government intervention adopt more effective mitigation and preparatory measures. Moreover, a thorough research/survey is to be done to find out the responsibilities and contribution of the Water Association Committee of Chamtal district towards the farmers of Arabmazari village. Currently, a cost-effective and immediate adaption is a practical option for the farmers, such as GIS, to create a localized map of the drought-prone areas.

Abstract

The management of building asset data has experienced many problems related to accessibility and storage issues. This causes difficulties for asset managers in managing and developing buildings after the construction phase. This research aims to develop a 7D Building Information Modeling (BIM) model of buildings to facilitate access to asset data in operational and maintenance activities. Autodesk Revit was used to perform BIM modeling and was integrated with COBIe and the cloud via QR code. The Faculty of Engineering Building Diponegoro University was used as a case study. Data was collected through observation, project documents, as-built drawings, technical specifications, etc. This 7D BIM model with COBIe plug-in is expected to address gaps in asset management, improve operational efficiency, reduce the risk of damage, improve the ability to classify assets in a systematic and integrated manner, and improve collaboration between stakeholders to increase the effectiveness of asset management significantly.

Abstract

Geopolymer concrete (GPC) has emerged as a sustainable alternative to conventional concrete, offering reduced carbon emissions and enhanced mechanical properties. However, variability in compressive strength due to material composition poses challenges to its broader adoption. Traditional evaluation methods are often time-consuming and resource-intensive, necessitating the development of precise and efficient predictive tools. This study introduces the optimized least squares moment balanced machine with feature selection (OLSMBM-FS), an advanced AI-based model for accurately predicting GPC compressive strength. The model incorporates backpropagation neural networks (BPNN) for weight assignment, least squares support vector machines (LSSVM) for hyperplane optimization, and the optical microscope algorithm (OMA) for hyperparameter tuning. The study employs a systematic dataset, implementing normalization and feature selection techniques to improve the accuracy and efficiency of the model training process. The OLSMBM-FS was validated using 10-fold cross-validation and demonstrated superior performance compared to other machine learning models. It achieved the lowest RMSE (4.279), MAE (2.291), and MAPE (6.59%), alongside the highest R (0.901) and R² (0.813), confirming its robustness and predictive accuracy. These findings highlight the potential of OLSMBM-FS as a reliable tool for predicting GPC compressive strength, supporting its broader application in sustainable construction practices.
