Abstract

Indonesia is the world's second-largest contributor to plastic waste, posing a significant environmental challenge due to the extremely slow decomposition of plastic materials, which can take up to 1,000 years. The accumulation of plastic waste has serious environmental consequences, including increased pollution and degradation of ecosystem quality. Therefore, raising public awareness of sustainable waste management has become increasingly important. One practical solution to this problem is the production of ecobricks, which are easy to manufacture using simple tools and readily available materials. This community engagement program aimed to enhance environmental awareness among residents of Nagari Lawang, Agam Regency, West Sumatra, by promoting ecobricks as an innovative approach to plastic waste management and encouraging environmentally responsible behavior to create a cleaner and healthier environment. In addition to reducing plastic waste, ecobricks provide economic opportunities by transforming waste into value-added products that can support community livelihoods. The program was implemented using educational lectures and hands-on demonstrations on converting plastic waste into ecobrick-based gate structures. This participatory approach enabled community members to gain both theoretical knowledge and practical skills in plastic waste recycling. The results showed that participants developed a better understanding of the importance of maintaining environmental cleanliness and public health through proper waste segregation. Furthermore, the community successfully acquired the skills to produce ecobrick products, particularly gate structures, for both household and communal use. Overall, the program contributed to improving environmental awareness, reducing plastic waste accumulation, and empowering the local community through sustainable waste management practices.

Abstract

Recirculating Aquaculture System (RAS) was chosen as an alternative for sustainable and low-impact mangrove crab cultivation. One of the main challenges in using RAS is determining the optimal feeding frequency. Inappropriate feeding can cause slow growth, increased mortality, and decreased water quality. This study aimed to analyze the effect of trash fish feeding frequency on the growth of mangrove crab (Scylla serrata) reared in RAS. The method used is an experimental method with a completely randomized design of 3 treatments and 4 replications. The research treatments tested were the frequency of feeding with FPP 01 once a day at 10 pm; FPP 02 twice a day at 10 pm and 5 pm; FPP 03 three times a day at 10 pm, 8 am and 5 pm. The parameters observed were survival, weight growth, carapace length growth, carapace width growth, specific growth rate and molting rate. The research data were analyzed using analysis of variance at a 95% significance level. The results showed that the frequency of feeding did not significantly affect the growth and survival of mud crabs in RAS. The frequency of feeding once is optimal to achieve maximum growth in mud crab cultivation using the RAS system with a survival rate of 100±0.00%, weight growth of 52.00±21.17 g, carapace length growth of 1.90±0.87 cm, carapace width growth of 1.60±0.70 cm, specific growth rate of 5.04±0.14%/day and molting rate of 67.00±0.58%.
