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.

Social and economic disparities between regions in Indonesia are still a serious problem, reflected in the high Gini Ratio and disparities in purchasing power. The Consumer Price Index (CPI) is an important indicator in measuring consumption patterns and price pressures between regions. This study aims to cluster 150 districts/cities based on consumption patterns through the CPI using the Agglomerative Hierarchical Clustering (AHC) and Spectral Clustering methods combined with Principal Component Analysis (PCA). The innovation lies in the comparison of the two clustering methods as well as the application of PCA to clarify the data structure. Evaluation with Silhouette Score and Davies-Bouldin Index showed that AHC gave the best results with four representative clusters (Silhouette: 0.76; DBI: 0.32), compared to Spectral Clustering with three clusters (Silhouette: 0.75; DBI: 0.54). Each cluster has different expenditure characteristics, useful for data-driven policy making. These results show that AHC is more effective in capturing interregional variations in consumption.

Teenagers, as the future generation of the nation, are facing significant challenges due to the rapid flow of globalization, technological advancements, and the weakening of social control and character education. This study aims to identify the factors contributing to the prevalence of promiscuity among teenagers, analyze its impact on social skills, and propose preventive and educational solutions. Using a literature review method, data were gathered from various relevant scientific sources published in the last five years. The results of the study show that promiscuity has negative effects on the physical and mental health, as well as the social relationships of teenagers, including teenage pregnancies, drug abuse, sexual deviation, and the decline of social skills. The minimal role of the family, the weakness of moral education, low self-control, and inadequate sex education are the main factors exacerbating this issue. On the other hand, the involvement of parents, religious education, and community-based approaches have proven effective in building the moral resilience of teenagers. The implications of this study highlight the importance of synergy between families, schools, and communities in instilling character values and equipping teenagers with healthy social skills to face the challenges of the era.

This article discusses alternative Islamic finance as a solution without usury in the contemporary era. The background to this research focuses on the negative impact of usury practices in the conventional financial system and increasing public awareness of the importance of ethical transactions. The aim of this research is to analyze the influence of sharia financial products on people's financial welfare and to evaluate the level of understanding and adoption of sharia financial products in society. This research uses quantitative methods with descriptive and inferential statistical approaches, which include surveys of various community groups who use sharia financial products. The research results show that Islamic financial products such as murabahah, musyarakah, and mudarabah not only encourage more ethical investments, but also increase local economic growth and support sustainable development. However, the main challenge faced is the public's low understanding of sharia principles, which hinders optimizing the potential of this sector. Financial technology (fintech) and collaboration between sharia financial institutions and the government are identified as important factors in expanding access and increasing financial inclusion. In conclusion, despite challenges such as a lack of understanding and the need for better regulation, Islamic finance has great potential to become a key pillar in a fairer and more sustainable global financial system. This research provides recommendations that more efforts should be made to improve education, transparency and collaboration to strengthen the Islamic finance sector in the future.
