Tilapia, as a high-value consumption fish, is one of the main reasons why fish farmers choose it as a key aquaculture commodity whose cultivation technology continues to be developed. Flow-through water system is one of the commonly used methods in tilapia farming in Indonesia. However, this method has several drawbacks, such as the continuous use of large volumes of water. Additionally, the environmental impact is a concern, as uneaten feed and feces discharged through the pond's outlet can pose a threat to the surrounding environment. To address these issues, technological advancements in tilapia farming continue to be developed, including the implementation of Recirculating Aquaculture System (RAS) and aeration systems. The use of these two technologies aims to improve water quality, reduce excessive water usage, and minimize environmental impacts associated with tilapia aquaculture activities. This study compares the two systems—RAS and aeration—using tilapia fingerlings measuring 5–6 cm over a 20-day cultivation period. Water quality and growth data were analyzed descriptively. The results showed that ammonia levels in the RAS system reached 0.08 mg/L, which falls within the optimal range for tilapia cultivation. In contrast, the aeration system showed ammonia levels of 1.6 mg/L, which exceeds the optimal threshold. Based on these findings, it can be concluded that tilapia fingerling cultivation using the RAS system is more effective at stabilizing and reducing ammonia levels in the culture medium compared to the aeration system.

The objective of this research was to determine the decline in freshness of skipjack tuna stored at room temperature. Fish freshness testing was carried out using organoleptic tests such as eyes, gills, odor and texture of the fish, as well as counting the number of bacteria taken from the gills of skipjack tuna. Skipjack tuna was taken from 3 different markets in Mataram City. Observations on the fish were carried out twice, the first in the morning after the fish was taken from the market at 09.00 WITA and the second observation at 15.00 WITA. The results of the study showed that in the morning the skipjack tuna was in a condition of declining quality freshness, then during the day the quality of the skipjack tuna decreased further with a condition that was almost rotten. The results of observations of total bacteria also showed that in the morning the total bacteria had passed the predetermined threshold and during the day the number of bacteria increased until it could not be counted.

This study aimed to evaluate the potential of ketapang leaf extract (Terminalia catappa) as an agent to enhance the survival and growth of Botia india (Botia lohachata) larvae, as well as its effect on the bacterial profile in the rearing medium. The experiment was conducted using a Completely Randomized Design (CRD) with five different treatment doses of ketapang leaf extract, namely 0 g/L (control), 0.3 g/L, 0.6 g/L, 0.9 g/L, and 1.2 g/L, each replicated three times. The observed parameters included survival rate, growth (absolute weight and absolute length), and the total bacterial count in the rearing medium. The results showed that the administration of ketapang leaf extract had a significant effect (p<0.05) on the survival, absolute weight, and absolute length of Botia india larvae. The treatment with a dose of 0.3 g/L resulted in the highest survival rate, reaching 95%, with an average larval absolute weight of 0.132 g and an absolute length of 1.35 cm. Quantitative analysis of the bacterial count showed that the administration of ketapang leaf extract, especially at a dose of 0.3 g/L, effectively suppressed bacterial growth in the rearing medium compared to the control group. Conversely, higher doses of ketapang leaf extract (0.9 g/L and 1.2 g/L) showed a tendency towards decreased effectiveness. The conclusion of this study is that ketapang leaf extract can be utilized as a natural alternative to improve the survival, growth, and health of Botia india larvae, with an optimal dose of 0.3 g/L. The utilization of ketapang leaf extract in ornamental fish farming can reduce dependence on synthetic chemicals that have potentially harmful environmental effects.

Educational Sharing Session Activities Regarding Turtles and Hatchling Release Activities held on November 9, 2024 in the Nipah turtle conservation area, North Lombok. This activity aims to increase public awareness and understanding of the importance of turtle conservation. This activity involves local communities, academics, and conservation area managers, with speakers from turtle conservation managers who provide education about the threats faced by turtles, such as illegal hunting, pollution, and habitat loss. In addition to the educational session, this activity also includes the release of hatchlings into the sea, providing an opportunity for participants to participate directly in turtle conservation. Interactive discussions that took place during the educational session allowed participants to ask questions and share knowledge about turtle conservation. The results of this activity show that the community is increasingly aware of the importance of their role in turtle conservation, and there is a commitment to be more involved in conservation efforts. Collaboration between the community, academics, and conservation managers is the main key to achieving the goal of sustainable turtle conservation. It is hoped that this activity can be a foundation for the development of further conservation programs that involve more parties and strengthen turtle conservation efforts in the future.

Turtles are a species that faces the threat of extinction due to habitat degradation, hunting, and marine pollution. North Lombok Regency has a coastal ecosystem that is an important habitat for turtles to lay their eggs, so conservation efforts are crucial. This community service program aims to optimize the release of hatchlings by increasing community and tourist participation as an ecotourism-based conservation strategy. The methods used include conservation education, community involvement in beach patrols, and hatchling releases involving tourists with a local wisdom-based approach. The results of the activities show an increase in community and tourist awareness of the importance of turtle conservation, as evidenced by their increased involvement in nest monitoring and hatchling releases. In addition, this program contributes to local economic growth through conservation-based ecotourism, where communities are starting to get involved in tourism support services. However, there are still challenges in terms of long-term funding and regulations that need to be strengthened to maintain a balance between tourism and conservation activities. In conclusion, a hatchling release program involving communities and tourists can be an effective and sustainable conservation model. With the right strategy, such as increasing education, partnerships with various parties, and supporting regulations, this program can continue to grow and provide ecological and socio-economic benefits for the community in North Lombok Regency.
