Abstract

In semi-intensive aquaculture, not all the feed given can be digested by shrimp; therefore, appropriate technology, namely, the use of probiotics, is needed. This study aimed to analyze the effect of probiotics in rearing media on the growth and survival of vannamei shrimp and to identify the optimal dose. This study used a completely randomized design (CRD). The variables used were growth rate, survival, and water quality (salinity, temperature, pH, dissolved oxygen, and ammonia). Data analysis was performed using Analysis of Variance (ANOVA). Data demonstrating a significant effect were analyzed using Tukey's continuation test. The results of this study indicate that the administration of probiotics to vannamei shrimp rearing media has a significant effect on the absolute weight and daily growth rate of shrimp. Meanwhile, the survival of vannamei shrimp did not have a significant effect on their growth of vannamei shrimp. The average water quality temperatures were 25 °C in the morning and 27 °C in the afternoon. The average morning pH was 7 and the evening pH was 7, the average salinity was 30 ppt, the DO average was 5.6, and the ammonia average was 0.3. The best dose in the study was treatment C with added probiotics at a dose of 2.5 ml/l.

Abstract

Each region has a different potential depending on its natural resources. Therefore, a separate study is needed to determine its potential; for example, it's potential for marine ecotourism. This study aims to determine potential strategies for developing marine ecotourism on Larea-Rea Island. This study used a descriptive qualitative method. The data collection techniques included observations and structured interviews. Data were analyzed using SWOT analysis by looking at the potential of using the Strengths, Weaknesses, Opportunities, and Threats found on Larea-Rea Island. The results of this study show that Larea-Rea Island has the potential to develop into a marine ecotourism area. The results of the SWOT analysis show that there are four alternative appropriate management strategies for building marine ecotourism on Larea-Rea Island:1) maximizing the promotion of marine tourism on Larea-Rea Island, 2) improving roads to tourist sites, 3) repairing and equipping facilities and infrastructure for tourism activities, and 4) conducting community development to become tour guides and tourism insights, and the importance of maintaining tourist sites.
