One of the natural freshwater feeds that have a high nutritional content and is easy to cultivate is Daphnia magna. The availability of D. magna at any time must be supported by daily feeding. Ulva lactuca macroalgae is one of the ingredients that have the potential to be used as D. magna feed because it has good nutrition and is abundantly available on the coast. This research was conducted for 17 days at the Integrated Laboratory of Madako Tolitoli University. The aim of the study was to determine the population growth of D. magna fed U. lactuca. D. magna was reared in a 25 x 25 x 30 cm aquarium containing 5 liters of green water and a stocking density of 20 individuals/L. The treatments tried were Treatment A = Without U. lactuca Soak (0 ml/L), Treatment B = U. lactuca Soak (3 ml/L), Treatment C = U. lactuca Soak (5 ml/L). The results showed that the administration of U. lactuca 5 ml/L (804.44 ind/L) had the highest population growth compared to the treatment of 3 ml/L immersion of U. lactuca (597.78 ind/L) and without administration of immersion of U. lactuca (482.22 ind/L).

Technological applications have also been applied, such as fish feed engineering and the use of Internet of Things (IoT) technology in feeding methods. This study aims to examine the potential of Dham Pulo village as a pilot model for freshwater fishery technoparks and identify supporting factors in the development of village potential management as a technopark tourism destination in Aceh Besar District.

The estuary is affected by the coastal reclamation which led to the fester sedimentation.

The modeling approach was applied to reconstruct the alterations around the estuary. The study aimed to estimate the changes on the shoreline, current patterns, and sediment transport patterns (suspended sediment), and to describe marine resources around the estuary of Wairuhu. MIKE 3 FM was utilized to reconstruct the pattern of flow and sediment transport changes, and coordinates plottings from satellite data were used to measure the coastline. The model was validated by using the data of tide and surface flow. The results showed the alteration pattern of the shoreline around the Wairuhu estuary occurred as a result of coastal reclamation. The flow validation (mooring and model) using RMSE was 0.38 which meant there was no difference between the model and mooring. By the model, the flow pattern that passed through the APG was following the tidal pattern. The changes in the tidal platform also occurred on the sediment transport pattern that formed the total distribution pattern of SSC (suspended sediment concentration).

The level of exploitation is high, and it is suspected that there has been overfishing in several areas. Cultivation efforts need to be done to maintain the population in nature. The natural rate of gonad maturation and spawning in H. scabra broodstock is relatively slow, so efforts are needed to speed it up, among other things by administering hormones. This study aimed to stimulate (1) gonad maturation and (2) H. scabra spawning. The study used a completely randomized design (CRD) with 3 treatments and 3 replications in 2 stages using broodstock measuring 250–350 g/head.

This study used a survey method while collecting data using a purposive sampling method. Mangrove density was obtained through the line transect plot method. The sediment type test used the dry sieving method, the total organic matter (BOT) test used the loss on ignition (LOI) method, the statistical test used the multiple correlation method. All data was then analyzed in a quantitative descriptive manner. The results of the study are that the type of sediment in Tunda Island mangroves is dominated by silty sand and sand. The total organic matter contained in mangrove sediments ranges from 2.40% - 3.62% which is included in the moderate to high category.
