Abstract

Bacterial deseases are seriousness problem in aquaculture. The uncontrolled of quality degradation of pond sites because of wastes and organic matters decompotition and also global climate changes has been predicted affect triggered the bacterial infections. Vibrio harveyi is one of patogenic bacteria which againts Tiger shrimp (Penaeus monodon). The recovery strategies has been applied both in the rehabilitation of pond sanitary and also it has been focussed in curative methods to overcome infection activities. The usage of synthetic antibiotics has been reported gift any negative effects, either for environment and rised pathogenic resintance because of uncontrolled exposure.Environmental friendly and based on biological methods has been promoted to overcome this problem. The usage of antibacterial agents derived from natural compounds  has been recommended as an effective method. Several marine resources has been predicted as candidates of antibacterial agents againts Vibrio harveyi. Several seaweeds (macroalga) and seagrass has been explored in this research at in-vitro level of study to inhibit the activity of Vibrio harveyi. The result showed that all of the crude extracts derived from seagrass (Thallasia sp) and several kinds of seaweeds  (Padina sp, Gracilaria sp and Sargassum sp) could inhibit the growth of Vibrio harveyi from the lowest concentration level (10 µg/mL). The highest inhibition activity has been showed from the antibacterial sensitivity test of crude extract of Thallasia sp at the concentration level of 10.000 µg/mL.                                                                                                                                  Keywords : macroalgae, seagrass, secondary metabolite, antibacteria, Vibrio harveyi

Abstract

Mangrove ecosystems are generally found in all coastal areas of Indonesia, which are affected by tides and inundate these ecosystems along the coast. The function of the mangrove ecosystem as ecotourism is an alternative that can be developed in coastal areas. The purpose of this study was to identify the diversity of flora and fauna, determine the allocation of mangrove ecosystem land for ecotourism and determine the carrying capacity of the mangrove ecosystem area to be used for ecotourism. This research was carried out from January to February 2021 in the Tanjung Lesung area, Banten, with three research stations based on the initial survey and the data provided by the manager. The data taken in this study are mangrove ecosystems, associated biota, mangrove thickness, and respondents from visitors who aim to find out how long it takes their visit. The results obtained are there are nine types of mangroves from six families. The mangrove density of the research location is 796 ind.ha-1. The biota found at the research site found seven biota. The results of the calculation of ecotourism suitability at Station I have a value of 58.3% with the S2 category, and Station II has a value of 72.2% with the S2 category. Station III has a value of 33.3% with the S3 category. The calculation results of the area's carrying capacity for tracking activities are 180 people per day with a usable area of about 2200 m2.

Abstract

Biodiversity of macrozoobenthos in Pasir Island, Brebes, is under-explored. On the other hand, the baseline information regarding macrozoobenthos is essentially required for better future environmental management. This research aims to analyze macrozoobenthos community structure in the Pasir Island that has not been documented. Surveys were carried out in the rainy season. In this study, a total of 10 sampling locations were classified into two different groups that represent “control” and “disturbed” station. The main structural parameters of the macrozoobenthos identified at each station were specific richness (S), abundance (number of individuals m-2, N) and the Pielou’s index (J). Additionally, the pairwise comparison between groups was conducted by using analysis of similarity (ANOSIM) and the similarity percentage (SIMPER) to obtain the description of community structure. A total of 1054 specimens were counted from the “control” and “disturbed” stations. These specimens belonged to five animal classes, namely, Bivalvia, Gastropoda, Malacostraca, Cephalopoda and Echinoidea. ANOSIM and SIMPER analysis demonstrated that a significant difference was found between “control“ and  “disturbed“ stations with the percentage of dissimilarity value of 88.82%. In addition, environmental variables such pH, salinity and type of substrates contributed significantly to this difference. This result provides insight regarding macrozoobenthos diversity and ecological information that may contribute to further conservation management in the Pasir Island, Indonesia.

Abstract

Indramayu is a regencyin West Java with a coastline length of ± 114 km bordering the Java Sea and has a mangrove forest covering an area of 4060.5 ha. A small part (27,58 ha) of this mangrove forest is located Karangsong Village, Indramayu regency. Karangsong Indramayu mangrove forest has 4 types of mangroves namely Avicennia marina, Rhizophora stylosa, Avicennia alba, Rhizophora mucronata, where A. marina and R. stylosa dominated the are. The purpose of this study was to obtain the profile of nutrients in the coastal waters of Indramayu, identify the composition of mangrove vegetation, and to analyze the relationship between nutrients and mangrove vegetation composition in the coastal waters of Indramayu. The method used in this study was a survey approach method, quantitative approach, and data gained were analyzed descriptively. The results showed that apart from dissolved oxygen, the temperature, salinity, and pH in the waters of Karangsong Indramayu were classified to follow the characteristics of mangrove growth. The substrates at the research site silty loam and silty clay loam. Nutrient content was in the range of 0.211 mg/L – 0.252 mg/L(nitrate), 0.135 mg/L – 0.277 mg/L (nitrites), 0.51 mg/L - 0.74 mg/L (ammonia), and 0.109 mg/L – 0.140 mg/L (phosphate). The relationship between mangrove composition and nutrient profiles was directly proportional, where less nutrient content showed a decrease in mangrove growth
