Abstract

The goal of this study was to determine the habitat characteristics and population density of brittle stars in coastal area of Nyang-Nyang Beach, Bali. To facilitate the process, observations were made between November and January from 3:00 p.m. to 6:00 p.m., when the tide was at its lowest. The methodology of survey and descriptive comparative approach research was used. Purposive sampling was used to determine observation and sampling locations: two stations known to be brittle star habitats were chosen as research sites. The variables observed were two: biota community structure observations of brittle star variables at the genus level, such as abundance, diversity, evenness, and dominance, which were measured using 1 x 1 m plots. Environmental water quality variables such as beach characteristics, pH, salinity, water temperature, Dyssolved Oxygen, and current velocity are observed. Microsoft Excel was used to perform data analysis calculations. According to habitat analysis, the coast of Nyang-Nyang Beach provides an ideal habitat environment for Echinodermata, particularly the Ophiuroidea class, includes brittle stars. Nyang-Nyang beach had the brittle stars density, with 24 ind/m2 recorded. With an H' value of 0.514, but it was classified as having low diversity. The evenness index value on Nyang-Nyang Beach is 0,468, and there is no dominant genus along the coast of Nyang-Nyang beach because the dominance index value on this beach is close to 0.

Abstract

Important aspects that affect the level of welfare and the economy of fishermen are the socio-economic conditions and exchange rates of fishermen. The purpose of this study was to determine the socio-economic conditions and exchange rates of fishermen in the Sanur Kaja Village. Primary data was obtained based on observations, interviews, and questionnaires on respondents (samples) by purposive sampling, which includes data on social aspects (age, education, number of family dependents, and variety of jobs) and data on economic aspects (fishery income, expenses, and non-fishery income). All data were analyzed using a qualitative and quantitative approach, namely data analysis for calculating Fishermen's Exchange Rates (NTN). Based on the data obtained, the age range of fishermen is 28 years to 61 years, with varying levels of education ranging from not having finished elementary school, elementary school, junior high school, high school, and Diploma to Bachelor with the number of family dependents ranging from 1 to 6 people. The income earned varies from < IDR. 200,000 to IDR. 750,000 with expenses starting from IDR. 100,000 to IDR. 200,000 on 1 time went to sea. Based on the calculation results, the NTN is above 1, which is 1.59. With NTN above 1, this means that fishermen are said to be able to fulfill their basic needs.

Abstract

Kukusan Besar, Labuan Bajo, which is located in East Nusa Tenggara is one of the fertile waters that was a diversity of marine biota in the form of coral reefs. The purpose of this study was to determine the uniformity and condition of corals, especially the corals of the Acroporidae Family. This research was carried out from November 2021–April 2022. Determination of coral data collection points used a purposive sampling method. Retrieval of coral data using the underwater photo transect (UPT) method, with the transect spread along 50 meters in the direction of the coastline at every point of depth of 3, 5 and 7 meters. Underwater photos were analyzed using CPCe software. Coral cover at a depth of 3 meters is 29.12%. The depth of 5 meters is 36.54% and at a depth of 7 meters is 42.18%. At depths of 3 and 5 meters the corals of the Acroporidae family are dominated. The highest diversity index is found at a depth of 7 meters with a value of 2.20. The highest uniformity index was found at a depth of 5 meters with a value of 0.69. Family Acroporidae at a depth of 3 and 5 meters found 4 genera namely Acropora, Montipora, Astreopora and Anacropora, while at a depth of 7 meters there were only 2 genera namely Acropora and Montipora.
