In cultivating seaweed, obstacles often arise in the form of failures experienced by seaweed farmers or poor-quality yields. This study was aimed to develop alternative planting calendars for Eucheuma sp. in Mallasoro Bay, Jeneponto Regency based on sea surface temperature and distribution of chlorophyll-a obtained from Landsat-8 imagery. Image Processing Sea Surface Temperature and Chlorophyll-a were processed using ENVI 4.8 AND 5.3 software, the satellite images used were clean and without cloud disturbance. In this study, data analysis was carried out descriptively. The water temperature that is good for seaweed growth is 27-30˚C, for Mallasoro Bay Sea Surface Temperature which is suitable for seaweed cultivation, namely April, May, June, July, August, September, October and November. While the classification is based on the criteria for chlorophyll-a trophic status in marine waters, namely the range < 1 mg/L is classified as Oligotrophic, ≥ 1–3 mg/L is classified as Mesotrophic, ≥ 3–5 mg/L is classified as Eutrophic, and > 5 mg/L is classified as Hypertrophic. , from the results of image analysis for the distribution of chlorophyll-a in Mallasoro Bay, it shows that Mallasoro Bay is at the Mesotrophic level throughout the year or the fertility level of the waters is quite fertile because it is in the range of ≥ 1–3 mg/L. so that a seaweed planting calendar can be obtained in Mallasoro Bay, namely in January, February and December, preparation of tools such as cleaning and repair of seaweed planting tools can be carried out, then at the end of March, the end of May, the end of July and the end of September, the procurement of seaweed seeds is carried out. , in early April, early June, early August, and early October, seaweed seeds can be spread, then in mid-May, mid-July, mid-September, and mid-November, harvesting can be carried out, so that seaweed cultivation can be carried out 4 times in one year. cycle.","PeriodicalId":55804,"journal":{"name":"Jurnal Ilmu Kelautan Spermonde","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135647449","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Most of the activities of coastal communities may produce waste including fishing and tourism activities. Research on plastic waste in the Tourism Beach area of Muara Badak District was conducted to identify the type of mesoplastic, analyze the total weight, density and proportion of mesoplastic and determine differences in mesoplastic. This research was conducted at two tourist beach locations, namely Panrita Lopi Beach and Jingga Beach. The research method used was Purpusive Sampling method with recycling and making transect lines with a size of 100 m × 20 m, followed by dividing the transect into 5 lanes measuring 5 m x 5 m. Four types of mesoplastic were found, namely film, fiber, fragment and styrofoam. The amount of trash found on both beaches was 53 particles with the number of particles on Panrita Lopi Beach as many as 32 particles and Jingga Beach was 21 particles. The results of the composition of the percentage of waste obtained at Panrita Lopi Beach were 50% for fragment types and at Jingga Beach for 71% for filament types. The most common amount of trash found was at Panrita Lopi Beach, this was due to the fact that the number of visitors was greater than that of Pantau Jingga. The relationship between length and weight of waste at Panrita Lopi Beach was 94% while at Jingga Beach it was 58%.","PeriodicalId":55804,"journal":{"name":"Jurnal Ilmu Kelautan Spermonde","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135647450","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results of measurements of Cd metal in sediments showed concentrations ranging from 0.001 - 0.037 mg/kg. The concentration of Cd metal found was still in the low category. While the concentration of TOM in sediment ranges from 6.7 -30.3%, indicating a low concentration. The distribution of Cd and TOM showed that the farther from the estuary, the lower the concentration. Based on the results of the regression test, the relationship between Cd and TOM concentrations was 80.1%.

This condition is influenced by several factors, such as human activities and natural phenomena. Many efforts have been made by humans to overcome or repair coral reef ecosystems that have been damaged. One of the efforts made is to carry out coral transplants. The main goal of coral transplantation is to improve the quality of coral reefs such as increasing live coral cover, biodiversity and uniqueness of coral topography. The stages of the method carried out in the research include mapping the bottom of the waters (sounding); mapping conditions of water cover; transplantation process and monitoring. This study used the spider skeleton method for the transplant media. The results showed that the percentage of live coral cover ranged from 10% - 25% and it was found that rubble cover dominated up to &gt;70%. During the monitoring process, it was found that algae dominated almost all of the transplant media. The high nutrients and the lack of algae-eating fish resulted in a high algae cover found on the surface of the structure and had an impact on the death of the transplanted corals.

By applying the Modified Normalized Difference Water Index (MNDWI) method for coastline extraction, the research results show that the addition of coastal areas (accretion) as a dominant process in coastal stability in almost all coastal areas of Gorontalo City during the period 2000-2022, has experienced the significantly accelerated trend during the 2015-2022 period with an increase in the accretion rate of 60.15%. The rate of accretion in this period has caused an increase in the land area of coastal areas by 425.44% compared to the accretion that occurred during the 2000-2015 period.

This study was aimed to conduct an oceanographic analysis of the waters of Meosbekwan Island (Raja Ampat Regency) for the suitability of seaweed cultivation. Oceanographic data collection was carried out at three points (M1, M2, and M3) on the western side of Meosbekwan Island. Analysis of suitability for aquaculture was initiated with an analysis of key parameters, i.e., depth, protection and shipping traffic. The suitability analysis was followed by an analysis of the oceanographic parameters of the waters by weighting them using a ranking system. Furthermore, the final stage of suitability analysis was to evaluate the feasibility level of seaweed cultivation. The results showed that the depth of the waters on the western side of Meosbekwan Island ranged from 1.3 m – 5.8 m with an average depth of 1.5 m in the south (M1), 2.2 m in the middle (M2), and 3.9 m to the north (M3). Wave height during the study ranged from 0.1 – 0.3 m with an average value of 0.25 m at all points. The velocity of the water currents ranged from 0.08 – 0.25 m/s. The salinity of the waters was relatively homogeneous (30 - 31 o/oo). Water temperature also has small and relatively homogeneous variations with a range of 30 - 31˚C. The brightness of the waters ranged from 2.5 – 3.5 m. The bottom of the waters on the west side of Meosbekwan Island generally consists of coarse sand, rubble, and seagrass vegetation Enhalus acoroides and Cymodocea sp. In general, the oceanographic conditions of the waters are suitable for the life and growth of seaweed.
