Abstract

Sentiment analysis is the process of text data to understand the opinion contained in a sentence. The commonly used algorithm in this analysis is the Naïve Bayes Classifier. Naive Bayes Classifier (NBC) is a classification that uses statistical and probabilistic methods to group texts into several categories of sentiments such as positive and negative. The Indonesian simulator game analyzed is Angkot d Game. This algorithm is used to understand users' perceptions of the game and to identify the factors that affect user sentiment. The results show that the Naive Bayes Classifier has a high level of accuracy in classifying the sentiments of simulator game reviews. The findings of this analysis are also expected to provide insights to game developers about user preferences and complaints, allowing them to adjust features or aspects of the game to better meet user needs. This enables game developers to make significant changes to the games they develop, potentially increasing revenue in the Indonesian gaming industry and focusing more on games created by local developers. Keywords: Simulator Game, Sentiment analysis, Naive Bayes Classifier.

Abstract

Air quality is a comprehensive indicator that reflects air pollution. The air quality index is defined as a description or value of the transformation of individual parameters of interrelated air pollution, such as PM10, SO2, CO, O3, NO2 into one value or a set of values ​​so that it is easy to understand for the general public. Therefore, predictions of the Air Pollutant Standard Index in the future are needed for future policy decision making. SVR is a development of Support Vector Machine (SVM) for regression cases. The aim of this study is to predict the Air Pollutant Standard Index (ISPU) in the future using the SVR method. In the SVR method, the best kernel is used as an aid in solving non-linear problems, the Min-Max Normalization method for data normalization, division of training and testing data, selection of the best model with Grid Search Optimization. The best prediction results were obtained using a radial kernel with values with parameters ​​ε = 0.1, C = 10, and γ = 1 with the smallest error of 0.0086, with an RMSE of 0.0894. The RMSE value indicates that the model's ability to follow data patterns well. From the model on the radial kernel, the predicted results of the Air Pollution Standard Index from January 1, 2025 to July 31, 2025 were obtained which were not constant or fluctuating with an interval range of 41,14 – 58,69 and based on the Air Pollution Standard Index category, it was in the fairly good category index.

Abstract

This study performs a techno-economic analysis to assess the feasibility of developing chili sauce products incorporating fermented cassava flour as a local food ingredient. The evaluation covers both technical/technological and economic aspects. Technologically, the product exhibits favorable characteristics with a mean moisture content of 72% and pH of 4.01, supported by positive organoleptic test results. Economically, financial analysis indicates strong viability, with a Net Present Value (NPV) of IDR 40,138,730 an Internal Rate of Return (IRR) of 34.53%, a Benefit-Cost (B/C) Ratio of 2.25, and a Payback Period (PP) of 2 years and 1 months. The integrated findings from both technical and economic evaluations confirm that chili sauce formulated with fermented cassava flour is technically sound and economically feasible for commercial development. This product has significant potential to enhance added value, create new business opportunities, and support sustainable local food security. keywords: chili sauce, techno-economic, cassava

Abstract

This study aims to analyze the effectiveness of the Engineering Design Project learning model based on Ethno-ESD in actualizing sustainable environmental literacy in Chemistry Education students. The method used was a quasi-experiment with the design of the One-Shot Case Study involving 46 fifth-semester students. The environmental literacy measurement instrument which includes the aspects of Sustainability Environmental, Sustainability Social, and Sustainability Economic was validated using Aiken's V analysis. After Ethno-ESD learning was applied, the test result data was analyzed through normality, homogeneity, and one-way ANOVA tests to determine the effectiveness of the treatment. The results show that all data are distributed normally and homogeneously, thus qualifying parametric analysis. The ANOVA test produced a value of F = 20.365 with a significance of 0.000, which indicates that the Ethno-ESD learning model has a significant effect on improving students' sustainable environmental literacy. This finding confirms that the integration of local wisdom with the principles of Education for Sustainable Development is able to improve students' knowledge, attitudes, and sustainable behaviors in the context of environmental chemistry learning. The Ethno-ESD model is recommended as an innovative approach to strengthen sustainable environmental literacy in higher education.

Abstract

The quality of educational assessment plays a crucial role in measuring students’ competencies in the 21st century, particularly reading literacy as assessed through the Minimum Competency Assessment (AKM). This study aimed to analyze the content validity of an AKM reading literacy test instrument on acid–base theory and equilibrium using Aiken’s V method. The instrument was developed in accordance with the AKM framework, covering various item formats and cognitive levels, and consisted of 30 test items supported by six contextual reading passages. Content validity was evaluated through expert judgment involving nine validators, comprising five university lecturers and four senior high school chemistry teachers. The validators assessed each item based on six criteria: relevance to content, clarity of item formulation, functionality of answer options, alignment with AKM reading literacy components, appropriateness of completion time, and language accuracy. Quantitative data were analyzed using Aiken’s V formula, while qualitative feedback was used to refine the test items. The results showed that all 30 items obtained Aiken’s V values equal to or exceeding the critical value of 0.71, indicating acceptable content validity. One item demonstrated high validity, while the remaining items exhibited moderate validity. Expert feedback further contributed to improving clarity, contextual accuracy, and alignment with acid–base equilibrium concepts. Overall, the findings confirm that the developed instrument is content-valid and suitable for measuring students’ reading literacy in chemistry. Future research should focus on empirical validation to assess reliability and construct validity.

Abstract

Investment is investing capital with the aim of getting money or additional profits. When investing, you need to pay attention to risks that can cause losses for investors. One method that is widely used to measure investment risk is Value at Risk (VaR). VaR often has limitations, especially in capturing non-linear dependencies between variables, so a copula function is needed that can handle moderate to strong dependencies. One of the copulas used is the Archimedian copula with Frank subcopula. This article aims to estimate investment risk using the Value at Risk (VaR) method based on the Frank copula approach and to analyze the dependency structure between stock returns. The main steps in estimating VaR using the Frank copula are calculating the return of each stock, estimating the parameters of the Frank copula, carrying out data simulations using Frank copula parameters, calculating the VaR value using Frank copula. The data used in this research comes from shares of PT. Telkom Indonesia Tbk and shares PT. Indosat Ooredoo Hutchison Tbk. These two stocks have a positive correlation of 0.136. However, such a low correlation may still indicate for non-linear dependencies or tail dependencies that cannot be captured by linear correlations, so additional analysis, namely Frank copula, is required. The estimated Frank copula parameter value is 0.825. From the VaR estimation results, the risk obtained at a 90% confidence level is -0.0222, at a 95% confidence level it is -0.0281 and at a 99% confidence level it is -0.0383.
