Abstract

Insurance is a form of agreement between the insurer against the insured party (insurance company), where the insurer will pay a premium to the insured every month as a form of collateral for loss or damage that befalls him for certain events. Researchers took data by distributing questionnaires to respondents. Some covariate variables used in the study include: gender, vehicle age, vehicle insurance costs, vehicle use, vehicle mileage every year, and claims records in the last three years. Meanwhile, the dependent variable is frequency claim and claim severity. The researcher estimates the Generalized Linear Models (GLZ) parameters using the maximum likelihood estimation (MLE). The next step, researchers conducted a model compatibility test on the dependent variable using calculations on the Akaike Information Criteria (AIC), where the model chosen was the model with the lowest AIC value. Based on this, the researcher can determine covariate variables that affect the dependent variable and model it. The final step is the researcher calculates the probability of claim frequency, claim severity, and estimates the amount of pure premiums charged to respondents.

Abstract

Financial literacy is a crucial element in raising public awareness regarding financial management. It is closely linked to financial planning, with family financial planning being a key aspect of financial management, specifically in creating a monthly budget. According to the 2024 OJK survey, the financial literacy index for women (66.75%) is higher compared to men (64.14%). Based on these findings, the outreach team from the Mathematics Study Program at Universitas Terbuka aims to support OJK's efforts to improve family financial literacy among female parents at SDI Khazanah Kebajikan. The program implementation is divided into three phases: preparation (where the outreach team conducts a direct visit to the school), execution, and evaluation (via a partner satisfaction survey). The survey results reveal that participants were highly satisfied with the program, with a satisfaction rate of 95%. This satisfaction was attributed to various factors, including the speaker's knowledge, the perceived benefits of the program, the relevance of the topics presented by the outreach team in line with their expertise, the program's ability to address current issues, and the clarity with which the material was delivered.

Abstract

This study aims to analyze customer satisfaction at KOMIDA Cooperative Ajibarang by examining the influence of two main factors, namely loan products and service quality. The research adopts a descriptive quantitative approach utilizing the Fuzzy Mamdani inference system for data processing. Data were collected through structured questionnaires and interviews with active cooperative members as respondents. The use of fuzzy logic methods was chosen due to their ability to handle uncertainty and subjectivity in customer perceptions, thereby producing results that more accurately reflect real conditions in the field. The findings reveal that both the offered loan products and the quality of services provided play equally important roles in shaping customer satisfaction. Loan products were assessed as relevant to members’ needs, while services characterized by friendliness, efficiency, and clear communication enhanced the positive experience of members in interacting with the cooperative. Most respondents gave positive, indicating that the cooperative’s services and products have met, and in many cases closely aligned with, their expectations.

Abstract

Financial literacy training for elementary school teachers is a strategic initiative to instill basic financial management skills in students through curriculum integration. This community service program was conducted at SDN Pengasinan 1 with 26 participating teachers. The activities included material delivery, group discussions, thematic lesson plan development, and evaluation using digital pre-tests and post-tests via the Kahoot app. Pre-test results indicated a low initial understanding, with an average correct response rate of 44.29%. After the training, post-test results showed significant improvement, reaching 85.71%. Analysis revealed increased understanding in nine of ten financial literacy indicators, though a decline was observed in grasping basic concepts, suggesting the need to reinforce fundamental materials. Overall, the thematic and participatory approach proved effective in enhancing teachers’ competencies in financial literacy and demonstrates potential for replication in other elementary schools.

Abstract

This study aims to develop a mathematical model based on Integer Linear Programming (ILP) to map unmastered mathematical topics among senior high school students according to the cognitive domains of Bloom's Taxonomy, namely Knowledge (C1), Comprehension (C2), and Application (C3). The research method employed a quantitative approach, utilizing test result data from a 48-item instrument covering 16 mathematical subtopics, administered to 147 twelfth-grade students in the Natural Science program. The data were analyzed using LINDO 6.1 software to generate a profile of student mastery for each subtopic and cognitive domain. The results indicate that student mastery was generally higher in the Knowledge (C1) domain, with eight subtopics achieved, compared to the Comprehension (C2) domain with six subtopics and the Application (C3) domain with five subtopics. Out of the total 48 test items, only 19 items (39.6%) were mastered by the students, while 29 items (60.4%) were not. The Equations and Inequalities (X2) subtopic was the only material not mastered across all three domains. These findings suggest the need for learning strategies that place greater emphasis on strengthening conceptual understanding and contextual application. The application of the ILP model in this study proves effective as a diagnostic tool for identifying student weaknesses in a detailed and objective manner, thereby serving as a reference for teachers in designing targeted remedial programs. Furthermore, this model has the potential to be replicated in other schools to continuously monitor the development of student proficiency.
