Abstract

Higher education in Indonesia is experiencing rapid development in line with the demands of globalization and industrial revolution 4.0. Dynamic changes in the world of work demand new skills and continuous improvement of competencies. Massive Open Online Courses (MOOCs) are an innovative form of educational courses that can be accessed online via the internet. MOOCs offer open access to learning materials and are designed to accommodate participation from a large number of participants without physical limits on the number of participants. Education has a crucial role in creating quality human resources in the context of progress and challenges of globalization. Technical progress requires superior and competitive human resources, so appropriate and effective thinking and action is needed to overcome low learning outcomes in an effort to improve the quality of education. The research applies a quantitative analysis approach by adopting the Partial Least Square (PLS) method. The research presents recommendations for the development of MOOCs in accordance with the Technology Acceptance Model.

Abstract

The research objective is to analyze the Technology Acceptance Model (TAM) in measuring QR Code-based object-oriented programming learning multimedia in supporting vocational school students' learning on problem-based object-oriented programming (PBO) material. The TAM model variables used consist of Perceived Usefulness (PU), Perceived Ease of User (PEU), and User Acceptance of IT (UA-IT). The research respondents consisted of 35 students of SMK Negeri 1 Cimahi. The research stages consisted of familiarizing respondents with the use of multimedia, distributing TAM questionnaires, and testing the TAM model using SmartPLS software. The research results show that the average value of the user response questionnaire for QR Code-based PBO learning multimedia is 84.95% in the "Very Good" category. Based on the analysis of the relationship between TAM variables using PLS, it is known that the perceived ease of user variable has a positive influence on the acceptance of QR Code-based PBO learning multimedia, the perceived usage variable has a positive influence on the acceptance of QR Code-based PBO learning multimedia, and the variable perceived ease of use and perceived use. together they have a positive influence on the acceptance of QR Code-based PBO learning multimedia. This research is expected to provide an explanation regarding the use of TAM analysis in learning multimedia

Abstract

Vehicles have now become an essential basic need for society. Cars are one of the transportation tools that can be chosen for activities because they can accommodate more than one passenger and offer comfort while driving, eliminating concerns about bad weather during outdoor activities. When purchasing a car, consumers are faced with numerous criteria that influence the selection of the car they want, which makes it difficult for consumers to choose the right car. Several car specifications that consumers consider include the car's weight, passenger capacity, engine size, maximum power, and price. This study discusses the process of recommending the most suitable and needed cars for consumers. By using the fuzzy Tahani method, the processed car data will generate outputs in the form of recommended cars for consumers. This research is expected to assist prospective car buyers in determining the car that best matches their chosen criteria.

Abstract

Indonesia faces a high risk of earthquakes due to its location in the megathrust zone, including the M7 Sunda Strait segment, which has the potential for high-magnitude earthquakes. This study aims to model and estimate potential financial losses caused by earthquakes using the Earthquake Catastrophe Model, which consists of four main modules: hazard, inventory, vulnerability, and loss. Earthquake data obtained from the official USGS website were processed using the declustering method to extract mainshock events. The Generalized Pareto Distribution was then applied to model earthquake magnitudes, while spectral acceleration values were calculated using the attenuation function of Zhao et al. (2006). A Monte Carlo simulation was conducted to generate stochastic earthquake events and to simulate total aggregate loss (S), which was subsequently modeled using the Bernoulli-Lognormal Two-Part Model. The results indicate that, with a 95% confidence level, the estimated financial loss due to an earthquake in the M7 megathrust zone of the Sunda Strait will not exceed IDR 298 billion. These findings are expected to serve as a foundation for disaster risk mitigation planning and insurance financing schemes for local governments and the financial sector in Indonesia.

Abstract

Estimating claim reserves in an insurance company is crucial. Inaccuracy of the estimation results can affect the condition of an insurance company. Thus, the estimation results are expected to be close to the actual claims of a company. The purpose of this study is to compare the estimation of claim reserves using the Bornhuetter Ferguson and Munich Chain Ladder methods. The Bornhuetter Ferguson method utilizes internal information in the form of claim data and external information in the form of earned premium (company income derived from premiums paid by the insured). The Munich Chain Ladder method is a development of the Chain Ladder method that considers the correlation element between incurred claim data and paid claim data. In this study, both methods are applied to calculate the claim reserves of an insurance company in Malaysia. The estimation results obtained are the Bornhuetter-Ferguson method produces an estimate of claim reserves of RM2668458000 in paid data and RM3026005600 in incurred data, while the Munich Chain Ladder method produces an estimate of claim reserves of RM2938886000 in paid data and RM2134746600 in incurred data.

Abstract

This study aims to predict the population of Surabaya City in 2035 using the logistic model and to classify the livability level of each district based on population density. Secondary data were obtained from Badan Pusat Statistik (BPS) for the years 2010–2023. The population projection was conducted using logistic differential equations, while classification was carried out through agglomerative hierarchical clustering analysis using SPSS. The results indicate that districts with high population density, such as Sawahan, Bubutan, and Simokerto, fall into the low livability category. In contrast, districts like Rungkut, Sambikerep, and Gunung Anyar are categorized as highly livable due to their lower density. These findings suggest an inverse relationship between demographic pressure and livability. The classification output, visualized through maps, provides spatial insight to support urban spatial planning and policy-making. The study recommends equitable infrastructure development, population growth control, and service improvement in less livable areas to enhance the overall quality of life in Surabaya.

Abstract

This study conducted experiments using ensemble methods, hyperparameter tuning, and voting to improve software defect prediction across multiple projects using the Kamei dataset. Five machine learning models LightGBM, XGBoost, Random Forest, Extra Trees, and Gradient Boosting were applied to six projects: Bugzilla, Columba, JDT, Mozilla, Platform, and Postgres. Overall, the models demonstrated good performance when tested on datasets of projects with similar characteristics or strong relationships, such as Mozilla, JDT, and Platform, achieving accuracy and F1 scores above 80%. This indicates that defect patterns learned from one project can be effectively applied to similar projects. However, the models’ performance dropped significantly when predicting defects in the Bugzilla project from other projects, indicating notable differences in defect patterns or feature incompatibility. Differences in data distribution across projects remain a major challenge in CPDP. Therefore, domain adaptation techniques or feature transformation methods are needed to reduce inter-project differences, enabling the models to better recognize defect patterns across projects. Despite some improvements, data differences and class imbalance still limit prediction performance. Future research should address these challenges.

Abstract

This study aims to implement and measure the accuracy of the combined Analytical Hierarchy Process (AHP) and Simple Additive Weighting (SAW) methods in making decisions about providing social assistance in Purwoagung Village. This study is a type of applied research that focuses on solving real problems practically by utilizing data obtained from the village government. Data were collected through observation, interviews, questionnaires, and documentation studies to ensure the validity and completeness of the information. In its implementation, data were analyzed through the stages of data mining, criteria weighting using AHP, and alternative ranking using the SAW method. The results showed that of the six criteria used, the head of the family's occupation had the highest weight (0.453), followed by home ownership status, number of dependent children, savings ownership, cooking fuel, and type of house floor. The alternative with the highest preference value of 0.866 was determined as the main priority recipient, while the lowest alternative obtained a value of 0.325. Accuracy testing using a confusion matrix showed an accuracy level of the AHP-SAW method of 92.11%, indicating very good classification performance. These results prove that the AHP-SAW method is effective in determining the eligibility of social assistance recipients objectively, systematically, and efficiently. This study recommends further development with additional methods to improve the accuracy and use of the results of this study by the village in preparing policies for the distribution of social assistance that are more targeted, fair, and transparent. Keywords: social assistance, community, Purwoagung Village, AHP – SAW method.
