This paper discusses the concept of demand and supply, both from the perspective of conventional economics and Islamic economics. In conventional economics, the relationship between price and quantity of goods demanded or offered is explained through basic laws that are widely known. Several simple illustrations, such as the case of chili prices and children's clothes, are used to facilitate readers' understanding of the movement of the curve and market equilibrium. Meanwhile, in Islamic economics, the principle of demand and supply still applies, but is framed by sharia values ??that emphasize justice, ethics, and social responsibility. Consumption and production are not solely directed at profit, but also consider aspects of usefulness and sustainability. Thus, Islamic economics offers an approach that is not only rational, but also morally charged.

The aim of this research is to evaluate the influence of macroeconomic factors such as interest rates, inflation and exchange rates on the movement of Bank Rakyat Indonesia (BBRI) share prices in the period 2020 to 2024. The analysis used is a quantitative method taking a multiple linear regression approach. The data used is secondary, obtained from other sources, namely the Indonesian Stock Exchange (BEI) and Bank Indonesia (BI). The analysis was carried out using multiple linear regression using EViews 12 software. The findings from the analysis show that the three independent variables do not have a significant impact on BBRI share price fluctuations, both in simultaneous and partial analysis. From the results of the analysis, it can be concluded that there is a relationship where interest rates and exchange rates have a significant positive influence on stock prices, while inflation shows a negative impact on share prices.

Handwritten digit recognition is one of the key challenges in the field of digital image processing and artificial intelligence, with significant potential in various applications such as automatic form input systems, handwritten data correction, and attendance systems based on handwriting. This study aims to develop a web-based information system capable of automatically recognizing handwritten digits using the K-Nearest Neighbors (KNN) classification method. The system is designed through several main stages, including image preprocessing (conversion to grayscale, thresholding, and image size normalization), feature extraction using the zoning technique, and classification using the KNN algorithm. This research utilizes the MNIST dataset, which contains thousands of handwritten digit images ranging from 0 to 9. The system is developed using the Google Colab platform, supported by Python libraries such as OpenCV, NumPy, and Scikit-learn. Test results show that the system can achieve an accuracy of over 90% at certain K values, indicating that the KNN method is quite effective and efficient in recognizing handwritten digit patterns. This system is expected to be applicable for various digitization needs of handwritten numbers in education, administration, and information technology sectors

Crime generates insecurities, which limit tourism in several ways: reduced tourist destination appeal, increased perceptions of the risk of being victimized as a tourist, harm to destination image, increased transaction costs, and reduced institutional quality. This study employed a panel data approach to investigate the impact of criminal acts on tourist arrivals in 35 Central Javanese districts/cities from 2020 to 2024. Control variables included tourist attractions, accommodation, restaurants, vehicles, and the COVID-19 pandemic. Findings revealed a significant negative relationship between criminal cases and tourist visits, underscoring security's crucial role. Conversely, tourist attractions, accommodation, and restaurants positively affected arrivals. As expected, the COVID-19 pandemic negatively influenced tourism. Notably, the study found no significant impact from the prevalence of violence against children and women or the ratio of vehicles. Comparative analysis (between tourism-based and non-tourism-based regions) shows that crime consistently deters and attractions consistently promote tourism in all areas. Still, accommodation positively impacts tourism-based economies, while restaurants promote tourism in both regions. These results highlight the necessity of enhancing security measures at tourist destinations, fostering the development of sustainable attractions, and ensuring adequate supporting infrastructure to stimulate tourism sector growth in Central Java.

This study aims to analyze the readiness of farmers in Parakan Village to utilize digital platforms for marketing agricultural products. The methods used include interviews, focus group discussions (FGDs), mentoring, and the distribution of questionnaires to 30 members of the Mawar Farmer Group. Findings indicate a shift in farmers' behavior from relying on middlemen to independently marketing their products through social media. However, survey results show low levels of information access, active participation, and understanding of digital innovation. Innovation and digital literacy are key challenges, although some farmers expressed a willingness to learn. Continuous mentoring and collaboration between farmers, academics, and the government are essential to support an inclusive and sustainable digital transformation in the agricultural sector.
