Abstract

Student loyalty is an important indicator of institutional sustainability and competitiveness in higher education. One factor that influences student loyalty is the quality of academic services provided by universities. High-quality academic services can improve students’ learning experiences and increase their satisfaction, which in turn may strengthen their loyalty to the institution. This study aims to analyze the effect of academic service quality on student loyalty, with student satisfaction acting as a mediating variable. This research employs a quantitative approach using path analysis to examine both the direct and indirect relationships among the variables. Data were collected from university students through questionnaires measuring perceptions of academic service quality, student satisfaction, and student loyalty. The results show that academic service quality has a significant direct effect on student loyalty with a coefficient value of 0.327. In addition, academic service quality has a significant indirect effect on student loyalty through student satisfaction with a coefficient value of 0.241. These findings indicate that better academic service quality leads to higher student satisfaction, which subsequently enhances student loyalty toward the institution. The study emphasizes the importance of continuously improving academic service quality in order to create better learning experiences and strengthen student loyalty in higher education institutions.

Abstract

The goal of this research is to predict or identify an object's class using its available attributes through classification. The aim of this research is to use the random forest method to develop a classification model and the binary logistic regression method to discover significant determinants in cigarette consumption expenditure in Gorontalo Regency. The findings indicated that the size of the home, the number of family members, and the head of the household's educational attainment all had a considerable impact. Only the household head's educational attainment, however, consistently influences the model and satisfies the goodness of fit requirements. In contrast, the random forest model outperformed binary logistic regression in the classification analysis when classification characteristics including accuracy, precision, recall, and f1-score were assessed. Consequently, random forest was found to be the most effective classification model in this investigation.

Abstract

Mathematics is a fundamental science that plays an important role in developing students' logical, critical, and analytical thinking skills. One of the main competencies in mathematics learning is conceptual understanding, but international evaluation results and field findings show that this ability is still relatively low, especially in the subject of integer operations. This study aims to analyse students' mathematical concept comprehension skills in integer operations in Grade VII at SMP Negeri 1 Suwawa. The study used a quantitative descriptive method conducted at SMP Negeri 1 Suwawa, Bone Bolango Regency, Gorontalo, with 21 students selected through purposive sampling. The research instruments consisted of an eight-question essay test that had been validated and reliability checked, as well as semi-structured interviews. The data were analysed using descriptive analysis techniques through the calculation of mean scores, standard deviations, and percentages, then grouped into high, medium, and low categories based on four concept understanding indicators. The results showed that 67% of students were in the medium category, 19% in the high category, and 14% in the low category. The indicator of recalling concepts was the most mastered by students, while the indicators of selecting procedures and applying concepts in problem solving were the most challenging. These findings indicate that most new students have mastered procedural understanding but have not yet achieved deep conceptual understanding. Therefore, learning strategies that emphasise meaningful activities and the use of various representations are needed to improve students' understanding of mathematical concepts.

Abstract

This study aims to develop an interactive e-module on probability material for eighth-grade students of SMP Negeri 1 Tilongkabila. This research employed a Research and Development (R&D) method using the Plomp model, which includes preliminary investigation, design, product development, testing and revision, and limited implementation. The research subjects consisted of two material experts, one media expert, one mathematics teacher, and eighth-grade students. Data were collected through expert validation sheets and teacher and student response questionnaires, and analyzed using descriptive quantitative techniques.The results showed that the interactive e-module was categorized as very valid by material experts with a percentage of 98%, and valid by media experts with 81.54%. Teacher and student responses reached 89.17% and 87.78%, respectively, indicating very positive responses. Therefore, the interactive e-module on probability material is valid, practical, and suitable for use in mathematics learning for eighth-grade junior high school students..

Abstract

Penelitian ini dilakukan karena kurangnya pemanfatan teknologi yang ada disekolah sebagai media pembelajaran sehingga pembelajaran di dalam kelas sering di anggap membosankan dan kurang menarik oleh siswa serta tampulan buku pelajaran yang monoton membuat siswa menjadi kurang minat dalam proses pembelajaran. Sehingga tujuan dari penelitian ini adalah untuk menghasilkanmultimedia pembelajaran  yang menarik dan berkualitas untuk digunakan pada materi  koordinat kartesius kelas VIII SMP/MTs. Proses pengembangan multimedia pembelajaran menggunakan  model 4-D yang telah dimodifikasi.  menurut Thiagrajan,Semmel & Semmel yang terdiri dari tiga tahap pendefinisian (define), perancangan (design) dan pengembangan (develop).pengambilan data dilakukan melalui Lembar validasi, lembar kemampuan mengelola pembelajaran, lembar kaktivitas siswa, dan angket respon siswa. Siswa kelas VIII C SMP Negeri 1 Suwawa dijadikan sebagai subjek penelitian.  Hasil kelayakan media oleh ahli media diperoleh skor rata-rata 4,08, yang dikategorikan baik berdasarkan kualitas media yang ditunjukkan. Hasil kemampuan guru dalam mengelola pembelajaran skor rata-rata 3,72 termasuk dalam kategori baik.dan respon positif siswa mencapai diatas rata-rata 70%. Hal ini menunjukan bahwa multimedia pembelajaran interaktif dapat digunakan sebagai media pembelajaran yang dapat meningkatkan pemahaman peserta didik.

Abstract

This study aims to determine the factors that most influence the rate of recovery of pulmonary tuberculosis patients using the Cox Proportional Hazard model. In the case of the cure rate of pulmonary tuberculosis patients, not all independent variables meet the proportional hazard assumption, so the stratified cox regression model is used. The stratified cox regression model used is the stratified cox model with interaction and without interaction involving pulmonary tuberculosis patients in one of the Gorontalo Hospitals. The results showed that the variables of shortness of breath, previous pulmonary tuberculosis patients, and smoking habits were the most significant factors affecting the recovery rate of pulmonary tuberculosis patients.

Abstract

This research aims to enhance students' learning outcomes using the Problem-Based Learning model on the topic of Transformation. This study is a classroom action research conducted collaboratively between researchers and teachers involving 30 students in class IX of Satap Tobongon Public Junior High School in the academic year 2023/2024. The research was conducted in two cycles, each comprising three meetings. Instruments used in this study included teacher activity observation sheets, student activity observation sheets, attitude assessment sheets, skill assessment sheets, and learning outcome tests. Data collection was performed through observations and written tests. The research results indicate that the observed teacher activity, categorized as good and very good, increased from 69.44% to 86.11%. Similarly, the observed student activity, categorized as good and very good, increased from 59.38% to 84.38%. Students' learning outcomes improved in the cognitive domain from 66.67% to 86.67%, in the affective domain from 65.00% to 85.83%, and in the psychomotor domain from 67.50% to 85.00%. Thus, all assessment aspects have achieved the learning success indicators in cycle II through the use of the Problem-Based Learning model.
