Abstract

Poverty tends to occur in developing countries, including Indonesia. Poverty is a complex problem and requires a comprehensive approach in efforts to eradicate it. Handling poverty must be carried out appropriately and cover various aspects of people's lives. The negative impacts of poverty not only affect people's welfare, but also hinder economic development in the long term. Poverty has a negative effect on the economy and social welfare. To determine the prediction of poverty levels, one approach that can be taken is a time series model (time series). In this research, method Autoregressive Integrated Moving Average (ARIMA) is used for analysis and forecasting poverty levels. So that it can provide insight into poverty behavior and take appropriate steps both in controlling and alleviating poverty. ARIMA is a time series forecasting method that is suitable for forecasting various variables quickly, simply, cheaply and accurately. The research results show that the poverty rate for the next three years (2024-2026) is 14.17%, 13.93% and 13.72%, respectively. The ARIMA model is proven to be able to provide fairly accurate predictions and follow actual trends, making it useful for forecasting. The ARIMA(1,1,1) model can be used as a reference for future forecasting. The process of forecasting poverty levels does not only focus on predicting statistical figures, but also includes an in-depth analysis of the factors that cause poverty and the economic dynamics that influence it. This allows the government to develop policies that are more effective and responsive to social and economic changes occurring in society.

Abstract

Abstract The issue of stunting among children in Gampong Alue Pineung Timue is caused by inadequate nutrition intake over a prolonged period. This problem is of serious concern due to its impact on children's growth and development. The aim of this paper is to implement a stunting prevention policy with a public value approach as its foundation. The methods include workshops and educational mentoring for the community, particularly for stunting cadres in Gampong Alue Pineung Timue. These activities aim to enhance community understanding of factors contributing to stunting, such as political economy, health, sanitation, and environment. The results of this policy implementation demonstrate strong commitment from the Government of Gampong Alue Pineung Timue through Presidential Regulation No. 72 of 2021, encompassing various nutrition and health interventions. In conclusion, addressing stunting requires collective commitment and sustainable policy implementation from multiple stakeholders. Thus, the community in Gampong Alue Pineung Timue is expected to experience improved welfare and optimal child development through integrated and sustainable stunting prevention efforts. The implications of this research underscore the need for synergy between government and community in tackling stunting. Through comprehensive approaches like nutritional education, access to clean water, and adequate sanitation, it is expected to significantly reduce stunting prevalence in Gampong Alue Pineung Timue. Globally, these efforts also contribute to achieving global nutrition targets aimed at reducing the number of stunted children.

Abstract

The trend of refugee arrivals in Indonesia has become a pressing issue due to global conflicts, wars, and human rights violations. Accurate forecasting of these arrivals is crucial for effective planning and resource allocation by governmental and humanitarian organizations. This study aims to forecast refugee arrivals in Indonesia using exponential smoothing models, providing reliable predictions to support evidence-based decision-making and strategic policy planning. The dataset used in this research was obtained from the official UNHCR Indonesia repository, covering the period from April 2020 to July 2023. An exponential smoothing framework was employed, incorporating both single-parameter and two-parameter (Holt’s) models. The smoothing constants were optimized at α = 1.00 and β = 0.1237509, representing the level (Ft) and trend (Lt) components, respectively. A quantitative evaluation using key error metrics showed that both single-parameter and two-parameter (Holt’s) models captured data patterns accurately. The two-parameter model outperformed the single-parameter model (MAPE = 0.66, MAE = 84.57, RMSE = 132.63) and projected arrivals of 12.005, 11.913, and 11.821 for the next three periods. These results indicate that Holt’s model effectively represents the temporal dynamics of refugee inflows and provides a data-driven framework to support evidence-based refugee management and strategic policy planning in Indonesia.

Abstract

Course scheduling in higher education institutions is a complex combinatorial optimization problem involving numerous constraints such as lecturer availability, room capacity, time slots, and course distribution across semesters. Manual scheduling practices often result in conflicts, inefficient resource utilization, and prolonged preparation time. This study proposes a hybrid course scheduling system that integrates a genetic algorithm (GA) and constraint programming using the CP-SAT solver from OR-Tools. The GA is employed in the first phase to generate optimal course sections based on student enrollment, lecturer workload, and capacity constraints. The best solution produced by the GA is then refined using CP-SAT to generate a conflict-free timetable that satisfies all hard constraints, including lecturer, room, and time conflicts, while also optimizing selected soft constraints. The proposed system is implemented as a web-based application deployed on Microsoft Azure, enabling scalability and accessibility. Experimental results using real academic data demonstrate that the hybrid approach successfully produces feasible schedules with zero conflicts and significantly reduces scheduling time compared to manual methods. The results confirm that the integration of GA and CP-SAT provides an effective and flexible solution for university course scheduling problems.

Abstract

This study aims to develop a graduation prediction system for the MBKM Program using the Fuzzy mamdani method. The system is designed to process various academic criteria such as GPA, internship experience, and other supporting documents to provide an accurate projection of graduation probability. The implementation was carried out using data from 61 students of the Informatics Engineering Department at Universitas Malikussaleh. The Fuzzy mamdani method was applied through stages of fuzzification, rule formation, fuzzy inference, and defuzzification to produce the final prediction. The test results show that this method is effective in handling uncertainty and provides a high prediction accuracy, where 67% of students were predicted to graduate, and 33% were not. This system can be used by academic staff to evaluate student performance and provide more precise guidance, as well as to help students plan their studies to achieve graduation in the MBKM Program.
