Abstract

Rupat island in Riau Province has many beaches as tourist destinations. One of the beaches is Pesona Beach which is located in Teluk Rhu village, North Rupat, Riau Province. This beach has the beauty of white sand that stretches along the coast. This study was conducted in July 2021 with the aim of knowing the tourism suitability index and calculating the carrying capacity of the region to develop into a beach tourism destination. This research method used descriptive and qualitative method then the data is based on the parameters of the Tourism Suitability Index (TSI) and Regional Carrying Capacity (RCC). The final results showed that the tourism suitability index for four categories: beach recreation S2 (appropriate), swimming S2 (appropriate), fishing S1 (very suitable), and boating S1 (very suitable). The regional carrying capacity of the Pesona beach area for tourism activities can accommodate 821 people/day. If there is an excess of visitors, it will have a negative impact on the ecosystem, therefore it is necessary to pay attention to the operation of the tourist area so that it is preserved and sustainable

Abstract

This study aims to determine the secondary metabolic content of saponin contained in the active fraction of sea cucumber (Stichopus vastus) by using metabolic test reagents and thin-layer chromatography (TLC) analysis. The active fraction was given the reagent in the form of HCl 2N and strong acid then continued with analysis to determine the Rf value and lieberman-burchad reaction. The results of the metabolic reaction test showed that the active fraction contained steroidal saponin compounds characterized by the presence of a stable foam and the formation of a greenish-green color. TLC analysis produced a single stain with an Rf value of 0.9 and a bluish color reaction after being given Liberman-burchad which confirmed that the saponins contained in the active fraction of sea cucumbers were steroidal saponin.

Abstract

Tsunami that swept the Tanjung Lesung coast in 2018 caused Anak Krakatau to collapse in Sunda Strait which hit the coastal areas of Banten and Lampung. Tanjung Lesung is one of the worst areas affected. Tsunami in Tanjung Lesung has taken lives, damaged infrastructure, and caused terrible natural damage. One of the damages affecting residents' lives in the Tanjung Lesung coastal community is exposure to the marine ecosystem. The main ecosystem that has the highest productivity level is the coral reef. Coral biota is the main benthic biota of reefs that are directly affected by earthquakes and tsunamis. However, until now there has been no data on the status of coral reefs after the 2018 Sunda Strait tsunami. Therefore, researchers feel the urgency of this research is high enough to determine the condition of coral reefs after the Sunda Strait tsunami in Tanjung Lesung. There are 3 research stations for data collection before the tsunami, and we conduct research in those 3 stations again after the tsunami. Then we added 3 research stations again, so there are 6 research stations. Observation of coral reefs uses the Line Intercept Transect (LIT) method. The line transect is made by stretching a roll meter with a scale parallel to the coastline along 25 meters with three replications with an interval of about 0-5 meters between replications so the total observed transect was 75 meters. The deterioration of coral reef conditions at three research stations (1-3) proved that the tsunami waves affected the damage to coral reefs. This has an impact on the diversity of coral reef species inhabitants that have decreased. Disturbance form coral-damaged structure and composition changes of the base substrate as habitat can have an impact on reef fish and coral reef inhabitants. So that this research is expected to be a reference for policymakers in determining rehabilitation steps for areas affected by the 2018 Sunda Strait tsunami.

Abstract

Laundry detergent waste is toxic and can harm the environment and aquatic life. This study aims to find out the effect of detergent waste on the growth and mortality of gourami (Osphronemus gouramy) seeds and the threshold value of laundry detergent waste that can still be tolerated by gourami seeds. This research was carried out from December 2020 to January 2021 at the Aquaculture Environmental Quality Laboratory, Faculty of Fisheries and Marine Science (FPK) University of Riau. This research method used an experimental method using a completely randomized design (CRD) method with three tests namely the preliminary test, acute toxicity test, and sublethal test. Observation of fish behavior and morphology during the test is described descriptively. In the preliminary test, the lower and upper threshold values were 10 ml L-1 and 100 ml L-1. Then in the acute toxicity test, the value LC50-96 hour was obtained at 30.1 ml L-1 with a biological safe limit value of 0.301 ml L-1. The best treatment obtained from the sublethal test was P1 with a concentration of 0.3 ml L-1 resulting in an absolute weight gain of 1.03 g, a specific growth rate of 1.56%, and a survival rate of 83.33%. The mortality rate is influenced by the concentration of detergent waste, the higher the concentration of detergent waste, the higher the mortality rate. Detergent waste that enters the waters affects the surface tension of the water so that the oxygen diffusion process is hampered, the reduced dissolved oxygen stresses the fish. Detergent waste can also enter the fish's body, irritating the gills and other organs, which can lead to death.
