Abstract

Student attrition presents a major challenge in higher education due to its direct impact on academic quality and institutional graduation rates. Detecting students who are likely to withdraw at an early stage is therefore essential to ensure that timely interventions can be made. This study investigates how three distinct feature selection techniques—Chi-Square, Information Gain, and ANOVA—affect the performance of Artificial Neural Networks (ANN) in classifying student outcomes. The data used in the experiment were drawn from academic and administrative records, which had been standardized through Min-Max normalization. The results demonstrate that each method contributes positively, with classification accuracies ranging from 88.71% to 91.37%. Information Gain emerged as the most effective approach, yielding the highest accuracy at 91.37% and a recall score of 97.29%, largely due to its capability to reduce entropy and isolate the most informative variables. ANOVA also performed consistently well with 90.82% accuracy, while Chi-Square was comparatively less effective, potentially due to its reliance on categorical variables that may not capture predictive nuances. These findings emphasize the strategic importance of applying robust feature selection to improve ANN-based prediction models. Ultimately, this research supports the design of data-driven systems aimed at reducing student dropout rates and strengthening academic retention strategies across higher education institutions.

Abstract

The economic problems of rural communities and the low utilization of household waste into economically valuable products remain challenges in efforts to improve community welfare. Used cooking oil waste, which is generally discarded directly, has the potential to cause environmental pollution if not managed properly. This community service activity aims to enhance the skills and economic independence of the community through training in making eternal candles in Gunungrejo Village, Kedungpring District, Lamongan Regency. The method of implementing the activities was carried out through several stages, namely preparation, socialization, practical training, evaluation, and follow-up community assistance. The training was conducted on December 24, 2024, using a hands-on method for processing used cooking oil into eternal candles that have utility and market value. The results of the activities showed an increase in the knowledge and skills of the community in utilizing household waste into creative products, as well as the emergence of motivation to develop home-based businesses centered on eternal candles. This activity has a positive impact on increasing environmental awareness, productive skills, and opportunities for sustainable economic independence of the community.
