Seagrass community structure in the waters of Terkulai Island, Tanjungpinang City
No full textSeagrass ecosystem is a coastal ecosystem where seagrass grows as the dominant vegetation and can live permanently below sea level. Of course, the existence of human activities that do not care about the coastal environment has an impact on changes in seagrass communities in supporting coastal ecosystems. This study aims to determine the structure of the seagrass community in Terkulai Island Waters, Tanjungpinang City, this research was conducted in May 2023. Determination of the sampling point was carried out using the purposive sampling method with 4 stations that have seagrass distribution. Observation of seagrass was carried out using the modified line transect method where the line transect was placed at the starting point where seagrass was found until the end point was not found, the transect placement was chosen based on the longest area of the seagrass stretch and as a benchmark the transect placement was squared 50 x 50 cm then each line transect length was divided by 10% to get the squared distance between transects. The results of the study found 3 types of seagrass in the waters of Terkulai Island namely Enhalus acoroides, Thalassia hemprichii, Halophila ovalis. Seagrass Thalassia hemprichiii has the highest density when compared to other seagrass species with density values ranging from 764 to 1928 shoots/m2. If categorized, the value of seagrass cover at each station is included in the medium category. For seagrass biomass the Enhalus acoroides type is larger when compared to other seagrass species. The results of PCA (Principal Component Analysis) showed that seagrass cover was closely related to the environmental parameter characteristics of depth, brightness, salinity

Socio-economic study of the community in the Ternate Nusantara Fisheries Port (NFP) area, North Maluku Province
No full textSocio-economic studies are closely related to society, their needs, and how to fulfill them. One way society can meet its needs is by processing natural resources, such as agricultural and fishery activities. Agricultural and fishery activities that do not pay attention to conservation principles can cause land degradation, such as erosion, landslides, and extinction of natural resources. Socio-economic studies influence people's behavior in managing natural resources to meet basic needs. North Maluku Province has an area of 145,801.10 km² and is surrounded by estuary waters. The purpose of this study was to determine the socioeconomic conditions of coastal communities domiciled in the Ternate Nusantara Fisheries Port (NFP) Area, North Maluku Province. This research was conducted from January 2024 - to March 2024 at the Ternate Nusantara Fisheries Port (NFP) Ternate, North Maluku Province. The research methods used were observation, interviews, and questionnaires processed using a Likert scale. The results of this study indicate that the income of fishermen is highly dependent on weather conditions during fishing, while their expenses are related to the cost of fishing equipment and the fishermen's lifestyle. The higher the income earned, the greater the expenses. The community who do not work as fishermen, the processing industry plays a very important role as the main job that can increase income around the Ternate Nusantara Fisheries Port (NFP)

Utilization of tempe dregs for the growth of tilapia fish (Oreochromis niloticus)
No full textThe objective of this study is to determine the impact of feeding tempeh dregs at varying doses on tilapia growth and survival (Oreochromis niloticus). The study was conducted from March to May 2023 in Wataliku Village, Kabangka District, Muna Regency. The study employed a completely randomized design with four treatments that involved the administration of tempeh dregs in the diet. These were designated as follows: treatment A (control) was commercial feed; treatment B was 10% tempeh dregs; treatment C was 15% tempeh dregs; and treatment D was 20% tempeh dregs. Each treatment was replicated three times. The data were subjected to analysis of variance (ANOVA) at a confidence level of 95% (α0.05). The study results demonstrated that the highest specific growth was observed with the addition of 20% tempe dregs, with an average of 2.97% per day. This was followed by 15% tempe dregs (2.47% per day), 10% tempe dregs (2.28% per day), and commercial feed (2.00% per day). The highest absolute growth was observed in the treatment that included 20% tempe dregs, with an average of 1.04 g per individual. This was followed by the treatment that included 15% tempe dregs (0.87 g per individual), the treatment that included 10% tempe dregs (0.80 g per individual), and the treatment that included commercial feed (0.00 g per individual). It should be noted that survival was 100% in all treatments. Analysis of variance (α0.05) demonstrated that administration of tempe dregs at varying doses had a statistically significant impact on the specific and absolute growth of tilapia larvae (Oreochromis niloticus)
