Abstract

Mangroves are plants that grow between tidal lines. Mangrove forests have very important ecological andeconomic functions, but are very vulnerable to damage if they are not wise in maintaining, conserving andmanaging them. This research was conducted in Kampung Baru Village, Penajam District, Penajam PaserUtara Regency, East Kalimantan Province. The purpose of this study was to identify the types ofmangroves and to determine the ecological conditions of mangrove forest vegetation in the mangroveecosystem of Kampung Baru Village. The method used is the Transect Line Plot method. The dataobtained were then processed by community structure analysis. The types of mangroves found in fourstations in the mangrove ecosystem of the Kampung Baru, consist of nine types of mangroves, namely:Rhizopora mucronata, Rhizopora apiculata, Ceriops decandra, Avicennia marina, Nypa, Avicennia alba,Avicennia officinalis, Avicennia rumphiana, Sonneratia alba, and from four families, namely:Rhizophoraceae, Sonneratiaceae, Canthaceace and Arecaceace. The highest density value was Rhizophoramucronata, namely 1.04 ind/m2, with a relative density of 149.8%. The highest frequency value for Rhizophora mucronata was 400. The highest value for closure was Avicennia alba (100.12 m2). Importance value index of Rhizophora mucronata (151.82%), the lowest analysis of all stations wereCeriops decandra and Nypa species and had very abundant species diversity.

Abstract

Research on dolphin populations in Solor waters is done in two stages through primary data collectionconducted in June until July 2017 and secondary data retrieval conducted in February 2018. The studyaims to know the total amount of species, species behavior, and sighting frequency of dolphins. Surveyswere conducted using a double platform boat. The survey successfully identified four dolphin speciesconsisting of Spinner dolphin (Stenella longirostris). Risso’s dolphin (Grampus griseus), Fraser’s dolphin(Lagenodelphis hosai), and Pantropical spotted dolphin (Stenella attenuata). The behavior of the dolphinsduring observation are feeding, travelling, and logging. Stenella longirostris is the most frequentlyobserved species with 632 sightings (91.33%) in June 2017 and 647 sightings (80.07%) in July 2017.

Abstract

Beras Basah Island is an object pride tourism in Bontang City. The island is located in the middle of thesea and surrounded by beautiful beaches by width about one hectare. In addition from being a beautifulisland with white sand, this island is also a water area surrounded by a lot of biodiversity such as a coralreefs, seagrass beds, and various types of fish. This study aimed to find out the Tourism Suitability Indexand area supporting effort for coastal tourism on Beras Basah Island, Bontang City, East Kalimantan. Thisresearch was conducted in March 2021. The research location was in Pulau Beras Basah city. Analysis ofthe data used Tourism Suitability Indeks based on the multiplication of weights and skors obtained fromeach parameter of Depth, Brightness, coast type, coast Width, Coastal Slope, Water Base Material,Current Speed, tracking of Hazardous Biota, Land Closure, Water Availability, and using Area SupportingEffort analysis Based on the size of the seashore area. The condition of the beach tourism suitability indexfor the four stations on Beras Basah Island is the north station 2,3, 2,5 east, 2,6 south and west station 2,5the category is very suitable even though the visual conditions in the field actually look general and aresuitable for ecotourims and tourims. The total area carrying capacity calculation results are estimated tohave a maximum capacity of 202 people/day in 5 hours/person.

Abstract

This research was conducted in April to August 2019 to determine the potential of Mangrove Ecotourism in the village Tanjung Limau, Muara Badak. The result of the suitability analysis show that the mangrove area of the Pangempang area is included in the appropriate or standard category (S2) namely 62%, which is suitable for development into ecotourism because it has a good density value and various type of mangrove and the presence of various types of biota such as birds, crabs, mollusca, fish and monkeys. Based on the type of mangrove shows that station I there are 7 type namely Brugeria gymnorhiza, Avicennia rumphiana, Avicennia officinalis, Rhizophora apiculata, Rhizophora mucronata, Rhizophora stylosa and Avicennia marina. Station II namely Brugeria gymnorhiza, Avicennia rumphiana, Avicennia officinalis, Rhizophora apiculata, Rhizophora mucronata, Rhizophora stylosa and Avicennia marina. Station III namely Brugeria gymnorhiza, Avicennia rumphiana, Avicennia officinalis, Rhizophora apiculata and Avicennia marina.

Abstract

This study aims to identify the types and management of ecotourism on Hoga Island, Kaledupa District, Wakatobi Regency. This research was conducted by observing three transects, divided into transect 1 (Hoga island gate area), transect 2 (lodging area on Hoga island) and transect 3 (tourist recreation center beach area) with shoreline survey methodology method with transect size of 5 m × 5 m. The results showed that the waste found on Hoga island belongs to the category of macro-type waste with a total of 64 and an abundance of 2.56 particles / m2 dominated by plastic by 75%. The most marine debris is found in transect 3 with an amount of 37 and a weight of 1,323 g. Meanwhile, transect 1 found 15 waste 777 g in weight and transect 2 as much as 10 waste weighing 268 g. The management of ecotourism on Hoga Island is regulated by the local government without involving the community and local village governments. The socioeconomic interests of the community are not accommodated in local government policies, so that individually local communities participate in the field of services in developing ecotourism and meeting needs. Some of the offers offered are transportation services, management of tour guide homestays, administrative managers, marketing of local products and cultural creations.

Abstract

Plankton as a basic component in the structure of life in the waters, spesifically as water producers can be used as one of the parameters in monitoring the quality of the aquatic environment. The existence of aquatic tourism activities and quantitative and qualitative plankton can be used to determine the fertility of a waters, by measuring the abundance and distribution of plankton found at each depth. The research station is divided into three sites, site A is the source of the entry and exit of sea water, site B is in the middle of the lake, and site C is located close to the freshwater spring. Based on the results of research in the waters of Danau Dua Rasa Labuan Cermin, 8 classes of plankton were obtained with 24 species, there are the Chlorophyceae, Cyanophyceae, Chrysophyceae, Dinophyceae, Mastigophora, Crustacea classes. Sarcodina and Rotatoria. The Danau Dua Rasa Labuan Cermin are included in the Mesotrophic waters group. Because the abundance value reaches 9,513 ind/L, in other words, Labuan Cermin waters have a moderate fertility level that can support the breeding and survival of aquatic organism and the continuity of a good photosynthesis process.
