Abstract

Digital transformation at the village level is a strategic element in promoting equitable development and improving public service delivery. However, the level of digital readiness across regions remains uneven. This study aims to classify the digital readiness of villages in West Java Province by utilizing data from Open Data Jabar (opendata.jabarprov.go.id) related to the number of digital villages, internet access, and village development strata. A Decision Tree classification algorithm was employed to categorize regions into two readiness classes: high and low. The modeling results indicate that the number of self-reliant (mandiri) villages and the percentage of villages with internet access are the most influential variables in the classification. Although internet infrastructure is available in most areas, it does not always correspond to the level of village digitalization. Districts with high internet access but a low number of self-reliant villages are still classified as having low readiness. The model achieved an accuracy of 83%, although its performance in identifying the high readiness class was limited due to class imbalance in the dataset. Spatial visualization was also used to highlight regional disparities in digital readiness. This study provides an early contribution to digital readiness mapping of villages using a machine learning approach in Indonesia.

Abstract

Pension fund management often faces challenges arising from uncertainties in actuarial variables, such as retirement age, years of service, salary levels, and interest rates. Inaccurate calculations may result in fund deficits or impose excessive contribution burdens on companies. This study aims to identify the optimal method for calculating pension funds to ensure the maximization of pension program benefits. The research employs secondary data from a limited liability company, with documentation as the primary data collection instrument. The data include employees’ dates of birth, dates of registration for work, employment commencement dates, and wage records. The analysis focuses on normal contributions, actuarial liabilities, and fund accumulation using the Accrued Benefit Cost (ABC) and Attained Age Normal (AAN) methods. The results indicate that the AAN method generates higher normal contributions than the ABC method, making it more effective in preventing pension fund deficits. Conversely, the ABC method offers a more evenly distributed cost allocation throughout participants’ working periods. The findings suggest that the differences in results between the two methods are influenced by the length of service and the salary levels of participants.

Abstract

Public health in West Java faces complex challenges, including disparities in healthcare access, malnutrition, and socio-economic inequalities across districts. These conditions require data-driven analysis to identify patterns of disparity and provide evidence-based guidance for policy intervention. This study aims to cluster districts/cities in West Java based on health and social indicators using Principal Component Analysis (PCA) for dimensionality reduction, followed by K-Means and K-Medoids algorithms for clustering. Data from 27 districts/cities during 2019–2024 were analyzed after standardization. PCA extracted two principal components explaining 61.4% of the total variance. Scree plot and silhouette results indicated three optimal clusters. Comparative analysis revealed that the average silhouette score of K-Means was 0.31, while K-Medoids achieved a higher score of 0.34, suggesting more stable and robust partitioning against outliers. In 2024, Cluster 1 consisted of regions with adequate healthcare facilities and lower prevalence of underweight children; Cluster 2 grouped regions with limited health infrastructure and higher malnutrition problems, while Cluster 3 showed intermediate conditions. Therefore, K-Medoids outperformed K-Means by producing more consistent clustering across years. These findings offer practical recommendations: Cluster 2 should be prioritized for interventions such as improving primary healthcare access and nutrition programs, Cluster 1 requires maintenance of service quality, and Cluster 3 should be targeted for gradual reinforcement.

Abstract: Creativity is one of the important skills that teachers must have today. Creativity can be defined as the human ability to generate new and valuable ideas. In addition, creativity is considered as a basic competency that needs to be possessed by students in higher education. The purpose of this study was to determine the creativity of prospective biology teachers and its relationship with students' knowledge mastery. For this purpose, a descriptive and correlational study was conducted on 13 biology pre-service students. The instrument used in this study was the Torrance creativity test based on 4 creativity indicators: fluency, flexibility, originality and elaboration. Descriptive and correlational analyses were conducted to identify students' creativity profiles and the relationship between students' creativity and their knowledge mastery. The results showed that there were three types of creativity owned by prospective biology teacher students, namely students with low (38.46%), medium (38.46%) and high (23, 07%) levels of creativity. The correlation test results show that concept mastery correlates with student creativity (r=0.3). The conclusion of this study is that prospective biology teacher students have different creativity, and there is a correlation between students' concept mastery and their creativity level so that there needs to be an effort from lecturers by designing learning strategies that can increase student creativity and concept mastery.
