Abstract

This study investigates the effect of a combination of manure and mycorrhiza on the quality and storability of tomatoes from the perspective of organic farmers in Lembang, utilizing a quantitative analysis with 140 samples. Data were collected using a Likert scale (1-5), and the analysis was performed using Structural Equation Modeling-Partial Least Squares (SEM-PLS). The results show that manure positively impacts fruit quality and storability, with a stronger effect on storability. Mycorrhiza had a more significant effect on fruit quality and also positively influenced storability. The study found that mycorrhiza is the more dominant factor in improving fruit quality, while manure plays a more significant role in enhancing storability. The findings provide important insights for organic farming practices in Lembang, suggesting that a combination of manure and mycorrhiza can effectively enhance both the quality and shelf life of tomatoes.

Abstract

This study explores the impact of the DSN-MUI Fatwa on cryptocurrency on the investment interest of Muslims in Indonesia. Using a qualitative approach with five informants, the research examines their awareness, perceptions, and decision-making processes concerning cryptocurrency investments. The findings reveal that the Fatwa significantly influences investment decisions, primarily by emphasizing ethical concerns related to gharar (uncertainty) and riba (usury). While many investors adhere strictly to the Fatwa's guidance, others seek Sharia-compliant alternatives to participate in the cryptocurrency market. The study identifies key factors such as trust, perceived risks, and opportunities, highlighting a cautious yet growing interest in ethically aligned financial instruments. These findings provide valuable insights for Islamic financial institutions and regulators aiming to address the evolving needs of Muslim investors.

Abstract

This study investigates the effect of service adjustments and interactive tour guides on foreign tourists’ willingness to pay at Bali tourist destinations. The research adopts a quantitative approach using a sample of 150 foreign tourists selected through purposive sampling. Data were collected via structured questionnaires measured with a five-point Likert scale and analyzed using SPSS version 25. Statistical techniques included descriptive analysis, validity and reliability tests, classical assumption tests, and multiple linear regression analysis. The findings reveal that both service adjustments and interactive tour guides have significant and positive effects on foreign tourists’ willingness to pay. The regression model shows that these two variables collectively explain 62.1% of the variation in tourists’ willingness to pay. Service adjustments—such as cultural sensitivity, language flexibility, and personalized itineraries—enhance perceived value, while interactive guides contribute to emotional engagement and trust, thereby increasing payment intention. The study provides theoretical contributions by integrating service quality theory, customer value theory, and social exchange theory in explaining tourists’ economic behavior. Practically, it offers strategic insights for tour operators and policymakers to enhance adaptive and interactive service quality to strengthen Bali’s tourism competitiveness and sustainability.

Abstract

The aquaculture sector has come to be recognized as a key engine of both economic growth and seafood production worldwide. Shrimp farming in particular, and aquaculture in general, are major contributors to local livelihoods and food security in Sumbawa, West Nusa Tenggara, Indonesia. However, as this industry expands, it will have to contend with issues pertaining to productivity, sustainability of the environment, and the long-term viability of the fishing industry. Innovations in shrimp breeding have been implemented in the area to solve these problems. The various effects of these advances on aquaculture productivity and the long-term viability of Sumbawa's fishing enterprises are examined in this qualitative investigation. The results show how innovation, productivity, sustainability, and the particular socio-environmental setting of the area interact in a complicated way. Shrimp growth and disease resistance have increased thanks to selective breeding techniques, but genetic manipulation is still up for discussion. Sustainable feed methods are a viable way to lessen the impact on the environment. Effective disease management, together with market access and adherence to international quality standards, are critical components of a sustainable fisheries enterprise. This study promotes sustainable aquaculture methods and the long-term success of Sumbawa's fishing enterprises by offering useful insights and suggestions.
