Abstract

This research aims to design and implement a smart farming monitoring system that is appropriate for the local conditions of North Aceh to optimize the production of leading vegetables and facilitate sustainable agricultural transformation. In line with the national agenda toward the digitalization of the agricultural sector, this research is part of a concrete effort to encourage the adoption of smart farming technology at the local level. North Aceh Regency has great horticultural potential, but it is not yet optimal due to the minimal application of technology. This research supports the development of agriculture based on local potential. The study also promotes a participatory and educative approach to increase farmers' digital literacy and reduce the technology gap between conventional and modern technology-adopting farmers. The Smart Farming monitoring system was successfully implemented using soil moisture, air temperature, soil pH, and light intensity sensors integrated into a web-based dashboard and mobile application. The implementation of this system was able to increase vegetable productivity by 18–22%, especially for mustard greens, chili, and tomatoes, compared to conventional methods. The system also contributed to the efficient use of resources, shown by a 25% savings in irrigation water and a 15% reduction in the use of chemical fertilizers. The farmer response was quite positive, although there are still challenges related to digital literacy among some older farmers. Overall, the implementation of Smart Farming in North Aceh Regency had a real impact on increasing productivity and cost efficiency while supporting sustainable agriculture in line with the SDGs.

Abstract

The rapid proliferation of online gambling in Aceh, despite the formal implementation of Qanun Jinayah as the legal framework for Islamic law, has posed a significant challenge to law enforcement and community governance. One of the most pressing issues is the absence of a secure, anonymous, and accessible reporting mechanism for citizens to report online gambling activities. This study addresses that gap by developing and evaluating a web-based reporting system named SIPELRA (Sistem Pelaporan Rakyat Aceh/Aceh People’s Reporting System). Employing a Research and Development (R&D) approach, the research was conducted through four stages: needs analysis, system design, implementation, and testing. The system was built using the Laravel framework and MySQL database, with strong emphasis on responsive design and data security to ensure user anonymity. Needs analysis revealed that community members prioritize simplicity, anonymity, and reliability in reporting mechanisms. System design was modeled using UML tools, including use case and activity diagrams, while the interface was developed with a minimalistic and culturally contextual design. Testing consisted of blackbox testing to validate functionality and a user satisfaction survey administered to 30 respondents. Results indicated that all core features operated successfully without major errors, and user satisfaction achieved an average score of 4.5 (90%), with data security receiving the highest rating (92%). Case analysis in North Aceh demonstrated diverse gambling practices, including slot-based games and chip trading, with mobile devices as the dominant medium. The findings confirm that SIPELRA is both technically feasible and socially acceptable, offering a strategic innovation for enhancing community participation and strengthening the enforcement of Qanun Jinayah in Aceh

Abstract

The transition towards Industry 6.0 demands the evolution of intelligent manufacturing systems beyond automation and digitalization towards integrated, human-centric, and resilient innovation ecosystems. The assessment of ecosystem readiness in the face of such complexity is essentially a multi-criteria decision problem with conflicting objectives and structural risk constraints. This study proposes a non-compensatory multi-criteria decision support system using the ELECTRE method to evaluate the readiness of Smart Manufacturing Innovation Ecosystems in Indonesia. Seven industry 6.0-oriented criteria are considered, including technology infrastructure readiness, digital connectivity, human capital capability, sustainability, governance, cybersecurity, and investment costs. The structured decision matrix is normalized, weighted, and processed using concordance-discordance analysis to obtain an outranking dominance relationship between the decision alternatives. The results show that ecosystem readiness varies, with regions with balanced digital, governance, and cybersecurity readiness exhibiting structural dominance, while regions with lower digital readiness but lower investment costs are vetoed due to non-compensatory decision rules. Sensitivity analysis shows that the ranking of decision alternatives remains robust with moderate weight/threshold changes. The ELECTRE-based non-compensatory decision approach is more appropriate than compensatory approaches in evaluating strategic industrial constraints pertinent to the industry 6.0 transition. The study’s contribution is the operationalization of industry 6.0 principles within a decision support system framework, providing policy-relevant prioritization results pertinent to the smart manufacturing development strategy in Indonesia.

Abstract

Exchange rate fluctuations are a major source of risk in international transactions. This study evaluates the effectiveness of currency options as hedging instruments using Value at Risk (VaR) and Sharpe Ratio, and assesses risk model accuracy through backtesting using the Kupiec and Christoffersen tests. Monthly closing prices of USD/IDR and MYR/IDR from January 2022 to January 2025 were obtained from Investing.com. Option pricing was calculated using the Garman–Kohlhagen model, while VaR estimation employed variance–covariance and historical methods. The results show that model accuracy varies across methods and currencies. The effectiveness of options as hedging instruments depends on model parameters, option type, and historical data characteristics.

Abstract

This study aims to cluster the provinces in Indonesia based on their level of potential disaster impact, which consists of hazard area, exposed population, physical losses, economic losses, and environmental damage, using the K-Means clustering algorithm and to evaluate the performance of the resulting model. The optimal number of clusters was determined using the Silhouette Coefficient and the Elbow Method with the Within-Cluster Sum of Squares (WSS) approach. The performance evaluation of the K-Means clustering was conducted using the Davies–Bouldin Index (DBI). Based on the selection of the optimal number of clusters, the Silhouette Coefficient produced the highest value at K=3, with a score of 0.699. Similarly, the Elbow Method showed a significant decrease in the mean WSS at K=3, indicating that three clusters were optimal. The performance evaluation using DBI for K=3 resulted in a score of 0.30. According to the principle of DBI evaluation, the closer the DBI value is to zero (without being negative), the better the clustering quality. Therefore, it can be concluded that the K-Means clustering algorithm successfully produced a very good clustering structure in grouping Indonesian provinces based on their potential disaster impact.

Abstract

This study aims to predict firm value using financial indicators, economic profit, and intangible capital through machine learning approaches. The independent variables include precautionary cash, leverage, asset utilization, short-term liquidity ratio, economic profit, and intangible capital, while firm value is measured using Price-to-Book Value (PBV). This research employs several machine learning models, including Linear Regression, Decision Tree, Random Forest, Gradient Boosting, Neural Network, and Support Vector Machine. Model performance is evaluated using Mean Squared Error (MSE), Root Mean Square Error (RMSE), Mean Absolute Error (MAE), Mean Absolute Percentage Error (MAPE), and the coefficient of determination (R²). The results show that the Random Forest model provides the best predictive performance, explaining approximately 90% of the variation in firm value. Asset utilization emerges as the most influential variable, followed by short-term liquidity ratio and economic profit. Meanwhile, leverage and precautionary cash show relatively smaller contributions to firm value prediction. These findings indicate that firm value is primarily influenced by operational efficiency, liquidity performance, and value creation capability. The study demonstrates that machine learning methods provide a comprehensive and effective approach to predicting firm value using financial and value-based performance indicators.

Abstract

Makassar City has a varied monsoon rainfall pattern, so rainfall prediction is an important challenge in disaster mitigation and resource management. Data mining techniques such as classification with the Classification and Regression Trees (CART) algorithm can be used to classify rainfall and analyze historical data, but the risk of overfitting high-dimensional data requires dimension reduction such as Principal Component Analysis (PCA). To improve accuracy, the Output Statistics Model (MOS) approach that combines numerical data and observations is also used. The results of dimension reduction using the Principal Component Analysis (PCA) method showed that of the initial seven variables, only three main components (, , and ) were retained because they had eigenvalues greater than 1 and were able to explain the data variance significantly. The decision tree model that was formed resulted in an accuracy rate of 72.34% in training data. Where the model can classify most of the training data into the correct rainfall category. In the data testing, the model was able to achieve an accuracy level of 71.43%, which shows that the model has good generalization ability to new data and does not experience overfitting.

Abstract

Rapid urbanization requires accurate predictive models to support sustainable regional planning. This study proposes a Random Forest–based machine learning framework to predict regional growth and urban expansion using key indicators, including GDP growth, population density, infrastructure index, and night-time light intensity. The model demonstrates strong performance, achieving high accuracy (91%), R² of 0.94, and low RMSE (0.32), indicating robust predictive capability. Results show that infrastructure index, night-time light intensity, and population density are the most influential factors driving urban expansion, while GDP growth plays a secondary role. The model effectively captures non-linear relationships and produces predictions closely aligned with actual values across regions. The findings highlight the importance of spatial and infrastructural variables in shaping urban growth patterns. Methodologically, this study contributes a reproducible and interpretable framework, while practically offering insights for urban planning and policy formulation. The approach supports data-driven decision-making and promotes more efficient resource allocation. Future research should explore integration with remote sensing data, hybrid machine learning models, and spatio-temporal analysis to enhance predictive performance.
