High feed costs remain a major constraint in Nile tilapia (Oreochromis niloticus) aquaculture, requiring alternative feed formulations based on local ingredients with adequate nutritional quality. This study aimed to evaluate the proximate composition of fish feed formulated from snail meal, Azolla meal, and turmeric as a phytobiotic supplement. The study used an experimental method with a Completely Randomized Design consisting of three treatments and three replications. The feed formulations were P1, consisting of 55% snail meal, 25% Azolla meal, 5% turmeric, 10% corn flour, and 5% tapioca flour; P2, consisting of 39% snail meal, 39% Azolla meal, 7% turmeric, 10% corn flour, and 5% tapioca flour; and P3, consisting of 25% snail meal, 51% Azolla meal, 9% turmeric, 10% corn flour, and 5% tapioca flour. The analyzed parameters included protein, moisture, fat, ash, crude fiber, and carbohydrate contents. Data were analyzed using analysis of variance followed by the Least Significant Difference test. The results showed that feed formulation significantly affected all proximate parameters. P3 produced the highest protein content of 43.87%, fat content of 3.68%, crude fiber of 3.11%, and carbohydrate content of 7.28%, while also producing the lowest ash content of 28.46%. Moisture content ranged from 1.11% to 1.30%, indicating good feed storage stability. These findings demonstrate that the integration of snail meal, Azolla, and turmeric can improve the nutritional quality of alternative Nile tilapia feed and support locally based sustainable aquaculture feed development.

Nile tilapia (Oreochromis niloticus) culture requires an efficient and low-cost feeding strategy that can support fry growth and survival. This study aimed to analyze the effects of three types of natural feed, namely silk worms, earthworms, and snails, on absolute length growth, absolute weight growth, and survival of Nile tilapia fry. The study was conducted at the Aquaculture Laboratory, Faculty of Science and Computer Science, Universitas Muhammadiyah Gorontalo, from January 31 to March 2, 2026. An experimental method was applied using a Completely Randomized Design consisting of three treatments and three replications. A total of 45 Nile tilapia fry were reared in 9 plastic containers filled with 10 L of water, with 5 fish in each container. Growth and survival data were analyzed using ANOVA at the 5% significance level, while water quality was analyzed descriptively. The results showed that the type of natural feed had no significant effect on absolute length growth, absolute weight growth, and survival. Descriptively, silk worms produced the highest length and weight growth, with values of 2.99 cm and 6.37 g, respectively. Snails produced the highest survival rate of 86.66%. Water quality remained stable, with temperature ranging from 26.3 to 26.8°C, pH from 7.6 to 7.9, and dissolved oxygen from 5.2 to 5.6 mg/L. These findings indicate that silk worms are potential natural feed for improving growth, while snails support the survival of Nile tilapia fry.

Community service activities in traditional fish ponds on Tibi Island, Tarakan, aim to increase the productivity of fish and shrimp farming using a simple yet effective approach. The methods applied include manual pond maintenance, such as spreading molasses solution (EM-4) to improve water quality, removing pests such as snails and oysters, and routine net maintenance and water drainage. Feed management is carried out every three days to maintain the nutritional balance of fish and shrimp. Although without the use of sophisticated technology, the success of cultivation depends heavily on the experience and thoroughness of the farmers in managing the pond environment. Overall, this activity demonstrates that a simple and structured approach can support sustainable cultivation, increase productivity, and strengthen collaboration between the implementation team and the pond owners. It is hoped that this method can serve as a useful example for other traditional fish farmers in increasing aquaculture yields and supporting more efficient and environmentally friendly farming practices.

The Snail Canning Industry has the potential to impact the environment if wastewater with high organic compound content is not treated first. This study aims to analyze the performance of the Snail Canning Industry Wastewater Treatment Plant (WWTP) based on BOD, COD, and TSS parameters. The method used is descriptive, with primary data obtained through interviews and secondary data from laboratory test results. Measurements were taken at the inlet and outlet points of the WWTP, then compared with the quality standards based on the Regulation of the Minister of Environment No. 5 of 2014. The results showed that the WWTP succeeded in reducing the concentration of BOD from 201 mg/L to 6 mg/L, COD from 315 mg/L to 24 mg/L, and TSS from 25 mg/L to 6 mg/L. The reduction efficiency of each parameter was 97.01% for BOD, 92.38% for COD, and 76% for TSS. All outlet results met the established quality standards. This indicates that the wastewater treatment process at the IPAL functions effectively in reducing the levels of pollutant parameters in wastewater.

This study aims to analyze the population dynamics of rice plant pests through periodic monitoring during 8 weeks of observation. The research was conducted on 5 rice field plots using direct sampling method and yellow trap. The observation data included 23 pest species from various families such as Acrididae, Muscidae, Culicidae, Lycosidae, Pieridae, Chrysomelidae, and others. Observations showed that pest populations fluctuated during the observation period, with some species showing a downward trend such as mosquitoes (Culicidae) from an average of 19.6 individuals/map in the first observation to 14.2 individuals/map in the last observation, while some other pests such as snail carp (Pomacea canaliculata) showed significant variation. Pests that were consistently found in high numbers were mosquitoes, mealybugs (Pieris rapae), and gold snails. This periodic monitoring provides important information for integrated pest control strategies in sustainable rice cultivation.

This study explores the fatwa of Sheikh Muhammad Arsyad Al Banjari in the book Sabilal Muhtadin regarding the permissibility of eating haliling (field snails) and the prohibition of eating anak wanyi (bee larvae) with a focus on the health perspective. Sheikh Muhammad Arsyad Al Banjari stated that snails are halal food, while bee larvae are considered haram. This study uses a literature study method to analyze the legal basis and health implications of both types of food. The results of the study indicate that snails can be safely consumed if processed properly, because snails are rich in protein and nutrients, but require special attention in processing to avoid the risk of infection from parasites or bacteria. Conversely, consuming bee larvae can pose health risks such as allergic reactions and dangerous toxins, and can have a negative impact on the bee population and ecosystem. The conclusion of this study emphasizes the importance of understanding fatwas from a health and ethical perspective, as well as the need for education regarding food processing practices that are in accordance with sharia principles and modern health standards.
