Abstract

Gili Matra Aquatic Tourism Park has two conservation targets, namely biological targets and social, cultural and economic targets. Coral reef ecosystems, apart from being a conservation target, are also an attraction for tourists to visit. This research was conducted to determine the condition of the coral reef ecosystem to be used as the basis for the management of conservation areas. The research was conducted by collecting coral reef data either through surveys or secondary data from the results of previous studies. Coral reef survey using the standard Line Intercept Transect method. The survey results show that the condition of coral reefs in the utilization zone is better than the core zone. Live coral cover in the utilization zone reached 71% so it was categorized as good, while in the core zone it only reached 8% so it was categorized as bad. Coral reefs in the core zone are unable to recover even though the number of tourists has decreased during the Covid-19 pandemic. Therefore, the location of the core zone on Gili Air needs to be evaluated further so that the effectiveness of Gili Matra TWP management can be improved.  Key words: coral reefs; Gili Matra; Conservation

Abstract

Bedil Island is included in the Keramat, Bedil, and Temudong Small Island Park (TPK), which was approved by the Regent of Sumbawa. Administratively, this island is included in the Labuan Bajo Village area, Sumbawa, NTB. There is the existence of coral reef ecosystems in these waters that form a reef flat and reef slope profile, that stretches to the southwest and northeast. By its designation as a small island park, the coral reefs in Bedil Island are used as an underwater tourism object. This study aims to determine the current condition of coral reef cover in the waters around Bedil Island, especially in the eastern and southern parts of the island. Coral reefs in the north and west area are limited and there is the existence of seagrass beds. The line intercept transect method is carried out by spreading the roll meter as far as 50 meters on the east and south sides of the island with a depth of 2-3 meters. The coral lifeform that is tangent with the roll meter is then recorded and then analyzed for the average percent cover, clustering status, and coral mortality index. Coral reefs in the eastern and southern parts of Bedil Island are classified as very good/excellent because they have a percent cover value above 75%. In addition, the coral mortality index value is also relatively small which indicates that the corals are living well. Clearwater conditions and locations far from human settlements are thought to be factors that support coral survival. However, the presence of dead coral algae and rubble still indicates a threat of damage even though the value is small. Algae life on the surface of dead coral also indicates that the coral has been dead for a long time.

Abstract

Mangrove fruit processing in Jerowaru Village is still not utilized properly. Whereas mangrove fruit has great potential to be processed into various products. One form of processed mangrove fruit is to make jelly candy. Its sweet and sour taste makes this product an alternative that is much in demand by children and adults because it contains nutrients such as carbohydrates, vitamin C, phenols to anti-oxidants for the body and can have economic value for the surrounding community. One alternative is to conduct training in the manufacture of jelly candy made from raw materials of mangrove fruit. This is done as an effort to increase added value in making local food that has nutritional and economic value. The approach method applied in this service activity is an active participation method, namely by involving coastal community groups in making jelly candy. The enthusiasm of the local community to be able to take part in this activity was high, so we limited the number of participants to 25 people. The participants of the activity included the PKK women's group, youth youth groups and the Bale Mangrove Pokmaswas group. The material presented was about the process of processing mangrove fruit into jelly candy that can be used. The results of this service activity are increasing the knowledge and skills of the participants in processing Sonneratia alba mangrove fruit into jelly candy that can be consumed by all types of people. Furthermore, jelly candy can be packaged as attractively as possible to increase marketability and can be used as a characteristic of Jerowaru Village.

Abstract

Many policies, programs, and projects have been attempted to resolve waste problem in Indonesia, yet it is still one of the major environmental problems in the country. Several waste management practices exist at various levels, from the community level up to the industrial level. With increasing budget available for villages through various schemes, village-level management poses opportunities to solve waste problem in Indonesia. This empirical study uses Interpretive Structural Model (ISM) to examine variables contributed to youth-based waste management practice in Labuhan Bajo Village and the relationships among the variables. Participant observations and in-depth interviews were carried out to solicit information on important enablers for youth-based waste management. The model was developed using ten enablers. In this study, the model shows that the first driving power (at the bottom of the ISM) is facilitation, in this case, a NGO. On top of the model is the financial gain enabler. The MICMAC analysis shows that most of the enablers are in quadrant III (Linkages) category. Effective and efficient handling of the linkage enablers is necessary for youth-based waste management. This study offering enablers’ model gained from empirical study may offer fruitful insight for enhanced scholarship in waste management model at village level led by the local youth particularly in Indonesian context.
