Abstract

Abstract: This study explores the environmental impacts of layer chicken farming from an Islamic studies perspective, with particular attention to Islamic business ethics and Qur’anic interpretations related to environmental conservation. While layer farming contributes to economic and social development, it also poses notable environmental challenges. Adopting a Qur’anic interpretive framework based on Tafsir al-Mishbah by Quraish Shihab, this research focuses on the farming practices of a company named UD. Berkah Telur in Madiun. Employing a qualitative descriptive method, data were obtained through interviews and a review of relevant literature. The findings indicate that UD. Berkah endeavors to uphold the principles of Islamic business ethics, particularly regarding animal welfare and product quality. Nevertheless, challenges remain in fully integrating sustainable Islamic economic principles into all operational aspects. Despite these limitations, the enterprise demonstrates a clear commitment to social and environmental responsibility adhering Islamic teachings. As interpreted through Tafsir al-Mishbah, Islamic business ethics emphasize a vision of sustainability that extends beyond short-term profit orientation to include the preservation of the environment for future generations.

Abstract

Purpose -This study aims to address the challenges of teaching astronomy in higher education, particularly in institutions with limited observational infrastructure and urban light pollution. The purpose of this research is to investigate the effectiveness of Stellarium, a digital planetarium application, in enhancing students' conceptual understanding of astronomy concepts in Physics Education.Methodology - A quasi-experimental research design was employed, utilizing a pretest-posttest control group format. The sample consisted of 30 undergraduate students enrolled in the astronomy course, who were purposively selected and divided into an experimental group and a control group. The research procedure involved the development of Stellarium-integrated instructional materials, the implementation of teaching interventions, and the administration of pretests and post-tests to assess conceptual understanding. Additional instruments included a questionnaire to capture students' perceptions and documentation of classroom activities. Data were analyzed using paired sample t-tests, independent sample tests, and descriptive statistics.Findings - The results of the initial and final trials showed a significant increase in the experimental group's understanding of astronomical concepts. In contrast, the control group showed minimal improvement. The findings revealed a significant improvement in the experimental group's test scores, with an average gain of 16.6 points (p < 0.05). Students also expressed highly positive perceptions of Stellarium in terms of visual appeal, ease of use, learning motivation, and comprehension of celestial motion. These results suggest that Stellarium is an effective pedagogical tool for enhancing conceptual understanding of astronomy and fostering student engagement.Contribution- The study contributes to the growing body of research on simulation-based learning and offers practical insights into integrating digital technologies in science education, particularly in resource-constrained institutions. It also offers a model for adapting global digital tools to local educational contexts, thereby supporting curriculum innovation in Indonesian higher education.

Abstract

Introduction: Factors that cause high pneumonia cases, including age less than two years, population density, winter, antibiotic resistance, daycare attendance, exposure to cigarette smoke, nutritional status, and the influence of comorbidities. Methods: The research method used in this study is a quantitative study with a cross-sectional approach aimed at seeing the relationship between the effectiveness of early detection of pneumonia using an application system. The results of this study are used to develop prevention and control strategies for pneumonia that reach all levels of society, especially marginal groups and provide recommendations related to child pneumonia advocacy. Results: The results of this study are 1) People in Demak who have almost 50 percent of toddlers say the M-KIA application cannot operate or open the M-KIA application; 2) There are still many people in Demak who have toddlers who say the M-KIA application does not understand and is not clear in meeting the needs for their toddlers. Most mothers of children under five in Demak with the M-KIA application are able to detect pneumonia early; 3) The M-KIA application is less effective because parents of toddlers in Demak have not all felt the function of the M-KIA application in meeting the health needs of toddlers, especially for early detection of pneumonia. Conclusion: The obstacle faced by the community in DEmak is the lack of knowledge of using the M-KIA application so that only some understand so that they feel the use of the M-KIA application to detect pneumonia in toddlers early

Abstract

Many building materials that function as insulators to maintain indoor temperature stability during hot weather have been developed. One of them is porous ceramics applied to building walls as heat absorbers. Research related to the manufacture of porous ceramics began to emerge to find the optimal composition when applied as an insulator that can absorb heat well. In general, porous ceramics use activated carbon as a pore agent. Activated carbon can be obtained by carbonating agricultural wastes such as coconut shells, hazelnut shells, rubber fruit shells, rice husks, and cocoa shells. Research continues to develop in finding the best-activated carbon base material according to the required material characteristics. Researchers will take advantage of the abundant potential of local natural resources. The method used to make porous ceramics is to mix clay and activated carbon with a clay-carbon composition ratio of 100:0, 90:10, 80:20, 70:30, 60:40, and 50:50. The sample is made by mixing the two materials and then printed by dry pressing method with a load of 5 tons held for 10 minutes. After the sample is dried at room temperature, it is sintered at 900oC with a holding time of 3 hours. Next, the sample is characterized by determining density, porosity, and water absorption and then tested for thermal properties. After that, the surface morphology and elements in the sample are seen. The optimum composition of clay-carbon mixture is 70:30 grams.  Ceramics using activated carbon from rubber fruit shells are suitable as building construction materials as heat insulators because they can absorb heat up to 500oC.

Abstract

This study aims to analyze the influence of service rates and facilities on people's transaction decisions with service quality as a moderating variable at BRILink Agents in Pesantren Village, Kediri City. This study was motivated by the phenomenon of several BRILink agents that are close to each other and offer different service rates and facilities, thus creating competition and influencing people's decisions in choosing an agent. The research approach used is quantitative with a survey method through a questionnaire to 97 respondents who are BRILink agent users. The data analysis technique uses multiple linear regression tests to determine the direct influence and the influence moderated by service quality. The results of the study show that service rates and facilities have a positive and significant effect on transaction decisions. In addition, service quality has been proven to be able to strengthen the influence of service rates and facilities on people's decisions in making transactions. This emphasizes the importance of a combination of competitive tariff determination, provision of adequate facilities, and quality service in improving transaction decisions for BRILink agent users.
