Nutritional Value Composition Of Lamun Fruit Enhalus Acoroides From Samboang Beach, Bulukumba District, Sulawesi Selatan

As the main producer, seagrass leaves are the main food for several marine animals such as turtles and dugongs, while seagrass fruit which contains soft seeds can be consumed as food for humans, but it is not very popular and there is not much information regarding the nutritional content of seagrass fruit. One species of seagrass that is often found in the waters of Samboang Beach, Bulukumba Regency is the Enhalus acoroides species. This research aims to determine the proximate and essential metal content of Enhalus acoroides seagrass fruit taken from Samboang coastal waters, Bulukumba Regency, South Sulawesi. Determination of proximates, namely proteins, was carried out using the Kjeldahl method, fats using the extraction method with n-hexane solvent and essential metals, and while determination of essential metal content using the atomic absorption spectrophotometry method. The results of this research show that the water content is 87%, the ash content is 0.76%, the protein content is 1.2%, the fat content is 0.66% and the carbohydrate content is 10.38%. The essential metal test results show zinc (Zn) levels of 5.32 ppm, iron (Fe) of 7.2 ppm, and cobalt (Co) of 0.11 ppm.

Individual Incentives versus Team Performance: Lessons from a Game of Charades

In this article, we describe a modified game of Charades that was developed to facilitate a discussion on the basic principles of effective reward system design. Students are organized into small groups. Incentive schemes are then manipulated so that one player within the group strives for an individual incentive, while the rest of the team play for a group reward. Through this simple and “fun” activity, students learn firsthand what happens when individual and team interests and incentives are not aligned. This experiential learning activity also offers excellent opportunities to discuss group dynamics, communication and coordination, and the importance of maintaining a systemic view of organizational performance

COMMUNITY STRUCTURE OF MACROALGAE IN LEMUKUTAN ISLAND WATERS, WEST KALIMANTAN

Macroalgae or known as seaweed is one of the potential resources and is responsible for primary productivity in marine waters. Macroalgae plays an important role in marine ecosystems, provides food, oxygen, and habitat for several types of marine biota. Moreover, macroalgae have been reported as renewable resources in marine environment and widely used in various fields. The biodiversity and abundance of macroalgae are strongly influenced by aquatic environmental factors. Lemukutan Island is the largest inhabited island located in Bengkayang Regency, West Kalimantan and has the potential natural resources, including macroalgae. This Island can become a center for producing macroalgae that can be used to meet food needs both locally and domestically. The main objective of this study were to determine the community structure of macroalgae and the condition of the environmental physico-chemical parameters. The sampling locations were carried out in-situ at three stations and the determination of the sampling site was done by purposive random sampling method, by selecting an area based on the presence of macroalgae. The sampling of macroalgae was carried out using a quadratic transect with size of 10x10 m2 and the water quality parameters were measured using the AZ 8603 of WQC instrument. The study found 6 genera of macroalgae, such as Caulerpa, Halimeda, Padina, Turbinaria, Sargassum, and Gracillaria. Among the identified macroalgae, Phaeophyceae have the highest per cent contribution (50%), and Padina had the highest abundance (29.84 ind/m2). Lemukutan Island waters had a moderate level of diversity, high macroalgae uniformity, and dominance index in the low category. The aquaatic environmental factors influenced the abundance of macroalgae in Lemukutan Island waters.
