Abstract

A study of the mangrove ecosystem, gastropod community structure, and the influence of hydrooceanography at three district station points on Selayar Island was carried out from March to April 2017. This research aims to show mangrove density in various conditions, to reveal the structure of the gastropod community. and the influence of hydrooceanography. This research was analyzed using the Shannon Wiener index variation method and The Principle Component Analysis (PCA). Overall research findings show: 1) mangrove density values at three station points, namely: a) station 1 (0.35); b) station 2; and c) station 3 (0.16); 2) gastropod density values, namely: a) station 1 (3.44); b) station 2 (3.00); c) station 3 (2.81). The highest relative and absolute frequency value of all stations is Littorina Scabra and the lowest is Terrebralia Pallustris. The diversity index value for gastropod species at various stations ranges from 1.00 to 1.45 and the unity index value ranges from 0.25 to 0.31, which is still relatively low. The distribution pattern of gastropods classified as community groups at each station ranged between 2.53-8.53. The results of the Principle Component Analysis show that gastropods at each station are influenced by environmental factors (Hydro Oceanography).

Abstract

This study aims to determine the effect of differences in salinity on the level of osmoregulation of vaname shrimp larvae (L. vannamei). The research method used a completely randomized design with 4 treatments and 3 replications, namely treatment 17 ppt (A), 22 ppt (B), 27 ppt (C), and 32 ppt (D). The parameters observed were survival rate, absolute weight growth, and osmoregulation at the osmotic work rate (TKO) of vaname shrimp. Data analysis used descriptive. A salinity of 22 ppt gave the best results for survival rates, namely 92.22%, and the best absolute weight growth results, namely 1.03 grams at a salinity of 17 ppt. The results showed that differences in salinity had no significant effect (p > 0.05) on survival and growth in absolute weight. The TKO value of treatment A is media with a salinity of 17 ppt with a value of 654 mOsm/H2O which is the highest TKO value and is a shrimp that is hyperosmotic, namely a liquid whose osmotic concentration is higher than its environment, treatment B is a medium with a salinity of 22 ppt with a value of 500 mOsm/H2O which is the lowest TKO value and is a shrimp that includes isoosmotic regulation. The level of osmoregulation in vaname shrimp indicates a stagnant osmotic performance level so it can be stated that there is no difference in TKO based on salinity.

Abstract

Samalona Island is a small island that administratively belongs to the inner zone of the Spermonde Islands region with low live coral cover. One effort to improve coral conditions is to carry out vertical transplantation, but hydro-oceanographic conditions are thought to be an inhibiting factor, including sediment. The research carried out aims to determine the suitability of oceanographic parameters, estimate sediment rates, and determine the phosphate and nitrate in sediments. The research method used a field experiment method by taking water and sediment samples and installing sediment traps for 15 days. The parameters measured in situ are temperature, pH, current speed, salinity, and dissolved oxygen, while the ex-situ test is the dry weight of sediment, TSS, nitrate, and phosphate concentrations. Data analysis uses descriptive statistics and is categorized according to the evaluation instrument used. The research results show that the values for temperature, pH, current speed, salinity, and dissolved oxygen meet the standard criteria for coral-based on PP 21/2022. The sediment rate during the research period was 0,003 – 0,015 gr/cm2/day, so it was categorized as having the potential damage to corals with a mild to severe impact level. The nitrate concentration in sediment ranges from 0,19 – 0,25 ppm while phosphate ranges from 0,35 – 0,72 ppm, so it can be said to be waters with a medium trophic level (mesotrophic). The current speeds and sediment rates potentially accelerate nutrient concentrations and cause sediment resuspension, thereby closing coral polyps, especially on corals closest to the substrate where vertical coral transplant installations are installed.

Abstract

Coastal communities in Tinambung Subdistrict, West Sulawesi utilize the potential of traditional aquaculture in their area. POKDAKAN Sipodalle is one of the traditional aquaculture systems with a polyculture method between milkfish and vanamei shrimp. However, the constraints faced are declining production yields as a result of crop failure due to commodities attacked by pests and diseases. One of the crucial things that need to be considered is water quality. The purpose of the activity is to increase knowledge for the Sipodalle' Fish Cultivation Group (POKDAKAN) about traditional pond water quality. The availability of water quality measurement tools managed by partners to increase productive cultivation. The activity was held on Monday, June 22, 2024 at the Tandung Village Office Hall, Tinambung District, West Sulawesi Province. The main participants of this service were Sipodalle' POKDAKAN, but also involved students and lecturers. The method applied was training using presentation methods and hands-on practice on how to use water quality checking tools. The results of the service activities showed an increase in farmers' knowledge related to traditional pond water quality management, techniques and SOPs for checking pond water quality. Furthermore, from this activity, the group of farmers obtained water quality checking tools and farmers already know how to use these tools. The results of the training opened the insight of farmers to pay attention to shrimp health through water quality control from water quality measurement tools provided including DO meters, pH meters, and thermometers. The end result is that farmers can monitor water quality to prevent pond water problems including optimizing growth and better yields. The community service activities carried out have been carried out smoothly and well. Partner problems related to lack of knowledge about water quality are overcome through understanding water quality parameters effectively.
