Abstract

The Zero Water Discharge (ZWD) technology is highly effective for efficient water usage, reducing or even eliminating wastewater discharge typically associated with shrimp farming. Used water from shrimp ponds can be treated and recycled, preventing any liquid waste from being released into the environment. By utilizing energy generated from solar panels (SP), this shrimp farming practice becomes more environmentally friendly and sustainable. Renewable natural resources, specifically sunlight, are harnessed to operate the system without increasing the carbon footprint. The objective of this initiative is to transfer the appropriate ZWD technology based on SP in shrimp farming to the community of Gampong Alue Naga, particularly Dayah Bustan Assofa. The implementation method began with the initial observation by the team of volunteers of the shrimp farming practices in the dayah, which often faced various challenges, such as foul-smelling pond water due to poor water quality. Additionally, high electricity costs also hindered shrimp farming in the dayah. To address these issues, ZWD technology based on SP was applied. The results of the initiative indicate that the implementation of SP-based ZWD technology in vaname shrimp farming in Banda Aceh proceeded as planned, without encountering any significant obstacles in the field. The partners were very supportive and enthusiastic, requesting that their area be designated as a mentoring village by FKP USK. Future recommendations include enhancing capacity in marketing, particularly digital marketing, which is beneficial for expanding the market reach of farmers, enabling them to sell their products to a wider consumer base at better prices.

Abstract

Nile tilapia (Oreochromis niloticus) is an important aquaculture species due to its fast growth and high economic value, with feed quality being a key factor in production efficiency. This study evaluated the effects of dietary green tea (Camellia sinensis) leaf flour on growth performance, hematological parameters, and intestinal histology of Nile tilapia. A completely randomized design was applied with six dietary treatments (02.5 g/kg feed) and three replicates each. Supplementation at 1.5 g/kg produced the best growth response, with significant improvements (P 0.05) in weight gain (7.24 0.91 g), length gain (3.61 0.21 cm), and specific growth rate (2.67 0.20%/day), while feed conversion ratio, feed efficiency, and survival did not differ among treatments. Hematological values varied but remained within normal physiological ranges. Histological analysis indicated enhanced villi morphology, suggesting improved nutrient absorption. The bioactive properties of C. sinensis highlight its potential as a functional feed additive to improve tilapia growth and health, offering practical applications for sustainable aquaculture.Keywords:TilapiaGreen tea leaf flourFish growth performanceHematological parametersFeed additive
