Abstract

This study aimed to evaluate the effectiveness of Ketapang (Terminalia catappa), Banana (Musa sp.), and Teak (Tectona grandis) leaf extracts on enhancing the coloration of Channa maru (Channa marulioides). Body coloration in ornamental fish is an important aesthetic trait that significantly influences market value and consumer preference in the ornamental aquaculture industry. The experiment was conducted using a completely randomized design (CRD) consisting of four treatments (control, Ketapang extract, Banana leaf extract, and Teak leaf extract) with three replications. Parameters observed included color intensity using the Toca Colour Finder (TCF), carotenoid content in fish tissues, survival rate, absolute growth in length and weight, and water quality. The results showed that Ketapang leaf extract significantly improved fish coloration, yielding the highest TCF scores and carotenoid content (0.32 µg/g), followed by Teak leaf extract (0.22 µg/g), Banana leaf extract (0.07 µg/g), and the control (0.06 µg/g). Leaf extracts had no significant effect on survival rate or absolute growth in length and weight. Water quality remained within the optimal range throughout the experiment and did not act as a limiting factor. In conclusion, Ketapang leaf extract is recommended as the most effective natural additive to enhance the coloration and carotenoid content of Channa maru, followed by Teak leaf extract, while Banana leaf extract showed less effectiveness.

Abstract

This study aims to analyze differences in students’ levels of religious moderation in Islamic Religious Education classes at the junior high school level in Indonesia. The study employs a comparative quantitative approach using a survey method. The sample consisted of 120 students selected through proportional random sampling. The research instrument consisted of a religious moderation questionnaire with 25 items covering four indicators: national commitment, tolerance, anti-violence, and accommodation of local culture. Analysis results showed that the average religious moderation score for students at State Junior High School 1 in Cilegon City was 82.45, while students at State Junior High School 3 in Cilegon City scored an average of 78.10. A comparison test using the Independent Samples t-test yielded a t-value of 3.214 with p = 0.002 (p < 0.05), indicating a significant difference between the two groups. These findings suggest that the level of religious moderation among students at State Junior High School 1 in Cilegon City is higher than that at State Junior High School 3 in Cilegon City. The implications and benefits of this study suggest that schools need to strengthen learning strategies based on dialogue and local culture. These results also serve as a basis for teachers and policymakers to improve religious moderation programs in a structured and sustainable manner.
