Abstract

The mangrove ecosystem is a productive ecosystem with economic and environmental functions. This research was conducted to determine the value of the ecological index and the economic potential of molluscs (Gastropods and Bivalvia) found in the Lembupurwo Lagoon Beach (part of Wawar River Estuary), Kebumen District, Central Java, Indonesia. First, mollusc sampling was carried out on a 10x10 meter plot. So its existence also needs to be known and studied more specifically. Then, the ecological index of the species found is calculated using the Shannon-Wiener Diversity Index, Evenness Index, Simpson Dominance Index, Margalef Species Richness Index, and individual Density of each species. In addition, for the economic potential of molluscs using secondary data from scientific journals. Analysis of the data obtained descriptively with the support of tables and pictures. The study results showed that there were 17 species of molluscs consisting of 12 species belonging to the gastropod class and five other species belonging to the bivalves. The families with the most common species are Neritidae=3, Ellobiidae=2, and Littorinidae=2. Whereas in the Bivalvia class, each family was only found one species. The total molluscs found had a density value of 3.95 ind/m2. The Diversity Index (H') of molluscs was 1.48 (moderate), Evenness Index was 0.52 (moderate), Margalef Richness Index was 1.71 (low), and Dominance Index was 0.28 (no species dominated). Then, for the economic potential of the mollusks found, the economic potential is dominated by the food sector. The species that have potential in the food sector include: Faunus ater Linnaeus 1758, Isognomon ephippium Linnaeus 1758, Pilsbryoconcha exilis I.Lea, 1838, Polymesoda expansa Mousson 1849, and Anadara antiquata Linnaeus 1758.

Abstract

This study examines female leadership in developing Islamic educational institutions at SDIT 1 Daarussalaam, North Sangatta. The background of this research is the persistent social stigma that questions women's capabilities as leaders, particularly within Islamic education settings. This study employs a descriptive qualitative approach through observation and in-depth interviews with the principal, teachers, and staff, supported by secondary data from school documents. The findings reveal that female leadership at this school is based on professional competence and traits such as gentleness, empathy, and a collaborative approach. Supporting factors for success include the use of technology and strong team cooperation. On the other hand, challenges arise from limited communication with male colleagues and difficulties in interacting with male parents. This study contributes theoretically and practically by strengthening recognition of women's roles as leaders in Islamic educational institutions. It recommends the implementation of technology-based leadership training and the enhancement of professional communication while maintaining ethical conduct.

Abstract

This study investigates the impact of QRIS adoption on revenue growth and cost efficiency of micro and small enterprises in Yogyakarta using a panel data approach. Micro and small enterprises play a critical role in regional economic development, yet many still rely on conventional cash transactions. The introduction of QRIS as a standardized digital payment system aims to enhance transaction efficiency and financial inclusion. However, empirical evidence on its measurable economic impact at the firm level remains limited. This research employs a quantitative design using balanced panel data from 162 micro and small enterprises observed over a three year period from 2022 to 2024. The study applies Fixed Effects regression and Difference in Differences estimation to identify the causal impact of QRIS adoption on annual revenue growth and operational cost efficiency. Revenue growth is measured as the percentage increase in annual sales, while cost efficiency is proxied by the ratio of operational costs to revenue. The results indicate that QRIS adoption significantly increases annual revenue growth by approximately 6 to 7 percentage points. In addition, QRIS adoption significantly reduces operational cost ratios by about 5 percentage points, reflecting improved cost efficiency. The findings remain robust after controlling for firm age, firm size, and digital literacy. Digital literacy further strengthens performance outcomes, indicating that technological capability enhances the benefits of adoption. The study concludes that QRIS adoption contributes positively to financial performance and operational efficiency of micro and small enterprises in Yogyakarta. Digital payment integration functions not only as a transaction tool but also as a strategic instrument that supports productivity, competitiveness, and sustainable business growth.

Abstract

The quality of education is largely determined by the availability and management of adequate facilities and infrastructure. This study aims to analyze the management system for educational facilities and infrastructure and its impact on improving the quality of education in Islamic schools (madrasahs). The research method used a descriptive qualitative approach, with data collection techniques through observation, in-depth interviews with madrasah principals and administrative staff, and documentation studies at junior high schools (madrasahs). Data were analyzed using descriptive analysis techniques to illustrate the management patterns implemented. The results indicate that effective management of facilities and infrastructure encompasses four main stages: needs planning based on analysis of real conditions, procurement according to quality standards and priorities, optimal utilization in the learning process, and routine maintenance to maintain functionality. Madrasahs with a structured and systematic management system show significant improvements in the quality of learning, reflected in increased student motivation, teacher teaching effectiveness, and academic achievement. The study's conclusion emphasizes that professional and sustainable management of facilities and infrastructure is a strategic investment for improving the overall quality of education.
