This study aims to analyze the effect of the price of packaged cooking oil and bulk cooking oil on the elasticity of demand as one of the staple foods in Ciawitali Market, Garut Regency. The approach used is a quantitative descriptive method with a focus on associative analysis. Data were collected through observation and interviews in the period of September and October 2025. Then processed using simple linear regression analysis and demand elasticity analysis. The results show that the demand for both types of cooking oil is strongly influenced by price. For packaged cooking oil, it shows that 81.6% of the variation is influenced by price while the rest is influenced by other factors. For bulk cooking oil, it shows that 94.1% is influenced by price with an elasticity value of -6.346, which also shows elastic properties but lower than packaged oil which has an elasticity of -22.15. These results indicate that the increase in the price of packaged and bulk oil significantly reduces the amount of demand, with the greatest effect occurring on packaged oil because consumers tend to switch to more economical bulk oil.

This study aims to analyze and compare the price responsiveness of broiler chicken meat and native chicken meat in relation to household consumption patterns in Tarogong Kidul District, Garut Regency. A quantitative approach was employed using simple linear regression analysis based on primary data obtained through observations and interviews conducted in traditional markets. The analysis examines the extent to which price changes influence the demand for both commodities. The results indicate that broiler chicken shows a very strong relationship between price and demand, reflected in an R² value of 0.963. Statistical testing further demonstrates that price has a significant effect on broiler chicken demand (0.018 < 0.05), indicating that its demand is elastic and highly sensitive to price fluctuations. In contrast, native chicken shows an R² value of 0.698 and an insignificant price effect on demand (0.164 > 0.05), suggesting inelastic demand that remains relatively stable despite price changes. These findings reveal that consumers adjust their broiler purchase quantities more quickly in response to price changes, whereas native chicken consumption is more strongly influenced by taste preferences and habitual factors. The study concludes that there is a clear difference in price sensitivity between the two types of chicken. The implications of this research include the need for government price stabilization policies for broiler chicken to maintain household affordability, as well as quality improvement and marketing strategies for native chicken producers to strengthen competitiveness amid changing consumer demand.

This study aims to analyze the influence of service quality on consumer satisfaction at Katorroan Cafe Batutumonga, North Toraja Regency. This research uses a quantitative associative method with a questionnaire as a data collection tool involving 60 respondents who are visitors to the cafe. Data analysis was carried out using descriptive analysis, validity test, reliability test, classical assumption test, simple linear regression analysis, and hypothesis testing (t-test). The results showed that the service quality at Katorroan Cafe Batutumonga was in the good category, and consumer satisfaction was in the satisfied category. However, the results of the simple linear regression test showed a negative and significant influence of service quality on consumer satisfaction with a regression coefficient of -0.404 and a significance value of 0.000. This indicates that an increase in service quality is paradoxically followed by a decrease in consumer satisfaction in the context of this study. The coefficient of determination (R²) is 0.195, meaning that service quality contributes 19.5% to consumer satisfaction, while the remaining 80.5% is influenced by other factors outside the study.

This study aims to analyze the factors influencing the income levels of pineapple farmers in Siabal-Abal V Village, Sipahutar Subdistrict, North Tapanuli Regency. The research focuses on several key variables, namely land size, production quantity, production tools, and farming experience, which are presumed to be associated with farmers’ income. A quantitative research approach was employed, using multiple linear regression analysis to examine the simultaneous and partial effects of each variable on the income of pineapple farmers. The population of this study comprised all pineapple farmers in Siabal-Abal V Village, with a sample of 65 respondents selected through a simple random sampling technique. Data were collected through interviews and structured questionnaires designed in accordance with the research objectives. The results of the data analysis indicate that, simultaneously, land size, production quantity, production tools, and farming experience have a significant effect on the income of pineapple farmers. However, the partial test results reveal that only land size has a positive and significant effect on farmers’ income. Meanwhile, production quantity, production tools, and farming experience do not show a statistically significant influence. These findings indicate that land size is the dominant factor in determining the income level of pineapple farmers in the study area. Therefore, improving access to agricultural land or optimizing the utilization of existing land is an important strategy for increasing the income of pineapple farmers in Siabal-Abal V Village.

The development of social media as a space for disseminating information has presented opportunities as well as challenges in religious learning for students. TikTok, as a digital platform that is popular among the younger generation, provides a variety of Islamic content with the theme of fiqh and morals that have the potential to affect users' religious understanding. This study aims to analyze the influence of Islamic content on TikTok with the theme of fiqh and morals on the religious knowledge of students of the PAI Study Program UIN Palopo. The research method used a quantitative approach with multiple linear regression analysis of 268 respondents selected through random sampling techniques.
