This study aims to analyze the implementation of the Think Pair Share (TPS) learning model in improving problem solving skills in fractional materials for grade V students at SD Negeri 3 Mantingan. The background of this research is the low ability of students to solve fractional problems, mainly due to procedural misconceptions and lack of opportunities to discuss and construct understanding collaboratively. The method used is the Kemmis and McTaggart model Class Action Research (PTK), which consists of four stages: planning, action, observation, and reflection. The research was conducted in one cycle, involving 28 students as subjects. Data collection was carried out through evaluation tests (pre-cycle and cycle I) as well as observation of student learning activities. The results of the study showed a significant increase in problem solving ability. The average score of students increased from 36.43 in the pre-cycle to 93.21 in the first cycle, with a t-test of 25.18 and a p< value of 0.001, indicating a high significance. Learning completeness increased from 0% to 100%. The TPS model has been proven to be able to overcome misconceptions, especially through the peer scaffolding process in the "pair" stage, which helps students in identifying variables and choosing the right calculation operations. In addition, there was an increase in students' collaborative skills in terms of expressing opinions and asking questions, with an achievement range between 68% to 75%. The main obstacles faced in the implementation of polling stations are the management of discussion time and class noise. However, this was successfully overcome through the use of timers and Student Worksheets (LKPD) equipped with scaffolding questions. It can be concluded that the TPS model is an innovative and effective approach in improving mathematical problem solving skills contextually, in line with the principles of the Independent Curriculum.

Tempoyak is a traditional Indonesian fermented food made from the flesh of durian (Durio zibethinus Murr.), which undergoes spontaneous fermentation driven by indigenous microorganisms. The fermentation process generally occurs under anaerobic conditions and is primarily dominated by lactic acid bacteria (LAB), including species such as Lactobacillus, Leuconostoc, and Pediococcus. These bacteria play a crucial role in modifying the physicochemical properties of the product, including a significant reduction in pH, an increase in the concentration of organic acids, and the formation of volatile compounds responsible for tempoyak’s distinctive aroma and overall flavor complexity. In addition to enhancing its unique sensory profile, the fermentation process also extends the shelf life and introduces probiotic potential to the final product. This study aims to observe and analyze the microbiological and chemical aspects of tempoyak fermentation and to evaluate its potential as a local functional food with health-promoting properties. Laboratory tests and microbial analyses confirmed that the fermentation process not only retains essential nutrients but also promotes the growth of beneficial bacteria, provided the production conditions are hygienically maintained at all stages. The study emphasizes the importance of controlled fermentation techniques to ensure product safety and consistent quality. Furthermore, the findings reveal that tempoyak could serve as a promising probiotic-rich food that supports digestive health, contributing to the diversification of traditional Indonesian fermented foods. With its appealing flavor, cultural value, growing consumer interest, and potential health benefits, tempoyak holds significant promise for future development and commercialization, particularly in the field of functional food innovation rooted in indigenous culinary practices.

This study was conducted with the aim of evaluating the extent to which sand quality influences consumer purchasing decisions in the sand mining area located in Kalicilik Hamlet, Candirejo Village, Blitar Regency. The background of this research is based on the fact that in the construction and development sector, the quality of building materials is a very crucial factor. Sand, as one of the main components in construction, plays a vital role in determining the final outcome of a construction project. Therefore, the quality of the sand used is a primary consideration for consumers in choosing a location or sand seller. This study applies a quantitative approach using a survey method as a data collection technique. Respondents in this study consisted of 74 consumers who actively make purchases at the sand mining location. Data were obtained through the distribution of questionnaires containing questions related to consumer perceptions of sand quality and their decisions in making purchases. The collected data were then analyzed using simple linear regression analysis techniques run with the help of SPSS software. The results of the analysis indicate a highly significant relationship between sand quality and consumer purchasing decisions. This is demonstrated by the coefficient of determination (R²) of 0.540, meaning that 54% of the variation in consumer purchasing decisions can be explained by sand quality. Furthermore, the significance value of 0.000 strengthens this finding, indicating that the relationship is not a coincidence. Therefore, this study concludes that the better the quality of sand offered by the mining company, the higher the likelihood of consumers deciding to purchase. The implication of these results is that businesses in the sand mining sector need to pay special attention to the quality of the products they offer.

This study aims to analyze the efficiency and effectiveness of the use of mandatory spending in the management of regional expenditure in the education sector in 35 districts/cities in Central Java Province for the 2019–2022 fiscal year. Mandatory spending is an obligation to allocate at least 20% of the APBD for education, as regulated in national regulations. Efficiency is measured by the Data Envelope Analysis (DEA) method using an output-oriented approach and Variable Return to Scale (VRS) assumptions, where an area is said to be efficient if its efficiency score = 1. Meanwhile, effectiveness is assessed based on the comparison of output and outcomes, and is said to be effective when it reaches a percentage of 90–100%. The results show that there is a disparity between regions. Only Klaten Regency and Semarang City have shown perfect efficiency for four consecutive years. However, none of the areas achieved perfect effectiveness throughout the study period. The COVID-19 pandemic has also affected the dynamics of education budget realization, which has an impact on achieving efficiency and effectiveness. These findings provide strategic implications for local governments in developing education budget policies that are more optimal and oriented towards improving the quality of human resources.
 

Based on data from the Central Statistics Agency (BPS) from 2021 to 2023, the crime rate in Indonesia increased by 345,510 cases. This increase indicates social problems, particularly in the economic sector. Factors such as high unemployment, high poverty rates, and low minimum wages are the main causes driving crime. When people's basic needs are not met, the potential for deviant behavior to meet their living needs tends to increase. This study aims to analyze the influence of unemployment, poverty, and the Provincial Minimum Wage (UMP) on crime rates in Indonesia, both partially and simultaneously. The study uses a quantitative approach with secondary data sources obtained from official BPS publications. The data used is panel data, namely a combination of time series (time span) and cross-section (across regions/provinces) data for the period 2021–2023. Data analysis was performed using a panel data regression model with a Fixed Effect Model (FEM) approach after undergoing the Hausman Test. The results show that partially, the three variables—unemployment, poverty, and the UMP—have a significant influence on crime rates. Simultaneous testing also showed that collectively, these three variables significantly influence the crime rate. Furthermore, the coefficient of determination (R²) test result of 93.5% indicates that unemployment, poverty, and the minimum wage (UMP) variables are able to explain most of the variation in crime rates in Indonesia during the study period, while the remaining 6.5% is influenced by other variables not included in the model. This finding emphasizes the importance of improving the economic conditions of the community through job creation, poverty alleviation, and minimum wage adjustments as preventative measures to reduce crime rates in Indonesia.

This study aims to analyze the influence of Product Quality, Price, Sales Promotion, and Advertising on consumer purchasing decisions on the Bukalapak online store platform. This study used a quantitative approach with descriptive methods, aiming to illustrate the relationships between variables based on empirical data. Primary data were obtained by distributing questionnaires to 120 respondents who were active Bukalapak users in the West Medan District. The data analysis technique used was multiple linear regression with the aid of SPSS software to determine the effect of each independent variable on the dependent variable. The analysis results indicate that, partially, the variables Product Quality, Sales Promotion, and Advertising have a positive and significant influence on purchasing decisions. This means that the higher the product quality, the more effective the promotion, and the more attractive the advertisement, the greater the likelihood of consumers making a purchase. Conversely, the variable Price showed a negative and significant influence, indicating that inappropriate pricing can reduce purchase intention. Simultaneously, all four variables have a significant influence on purchasing decisions. The Adjusted R Square value of 70.4% indicates that this research model is able to explain 70.4% of the variation in purchasing decisions, while the dependent variable is influenced by factors outside the model. This study recommends that Bukalapak continue to improve product quality, develop competitive pricing strategies, strengthen promotions, and create creative advertising. Further research is recommended to consider additional variables such as product reviews, brand image, and service quality to enrich the analysis.
