FINANCIAL FEASIBILITY OF PURSE SEINE FISHERIES IN BALIMU VILLAGE, SOUTH LASALIMU OF BUTON REGENCY
Get PDFPurse siene fishery is a capital-intensive and labor-intensive business, but it carries considerable business risk due to climate change, increased operating costs, decreased fish stocks and unstable fish prices. The purpose of this study was to determine the financial feasibility of a purse seine fishery business in Buton Waters. This research was conducted in October 2020 in Balimu Village, South Lasalimu District, Buton Regency, Southeast Sulawesi Province. This study used a survey method using a questionnaire. Data were analyzed descriptively quantitative. The results showed that the average amount of profit earned during the peak fishing season was IDR 277,263,939 / month. The NPV value is IDR 4,021,035,338 (> 0), the Net B / C Ratio value is 6.63 (> 1), the R/C Ratio value is 6.10 (> 1), the IRR value is 2.87 ( > 15% interest rate), the payback period is 8 months and 5 days, and the ROI value is 2.31%.

DIVERSITY AND ABUNDANCE OF GASTROPODS IN KAWAL AND PENGUDANG BEACH, BINTAN REGENCY
Get PDFKawal Beach and Pengudang Beach are sandy beaches located in Bintan Regency, Kepualauan Riau Province. The two beaches have almost similar activities, is there are fishermen settlements. The difference is that Kawal Beach is located around beach tourism activities, while Pengudang Beach has no beach tourism activities. The purpose of this study was to understand how diversity and abundance gastropods in Kawal and Pengudang beach, then the similarity-based Bray-Curtis similarity in both locations. The method of determining the research location at Kawal Beach and Pengudang Beach is purposive sampling. The gastropod samples were collecting use transect with a quadrat of 1 m2 at the lowest tide zone along 100 meters toward the sea. They were taken by hand then put into a labeled zip lock plastic. Samples were then identified, documented and their diversity and abundance were calculated. A total of 42 species of gastropods were identified belonging to 15 families with an abundance index 3433 ind/m2 for Kawal Beach and 1564 ind/m2 for Pengudang Beach. Diversity of gastropods species are (H’) 1,83; (E) 0,5; and (C) 0,3 for Kawal Beach, (H’) 2,55; (E) 0,7; and (C) 0,1 for Pengudang Beach. Bray-Curtis similarity shown is PK1-PP1=0,33; PK2-PP2 = 0,34; and PK3-PP3 = 0,15. This study is important in providing information on gastropods that live in the Kawal dan Pengudang beach. For future research should focus on temporal research in more depth to provide knowledge of gastropods communities and their ecological importance
GROWTH AND SURVIVAL RATE OF VANAME SHRIMP (Litopenaeus vannamei) PL-10 ON DIFFERENT STOCKING DENSITY
Get PDFLitopenaeus vannamei is a commercial shrimp that has high economic value. In recent years, the main commodity contributing to the aquaculture sector in Indonesia is vaname shrimp. Vaname shrimp cultivation aims to meet the increasing market demand. One of the factors that influence the success of vaname shrimp cultivation is the stocking density. This study aims to determine the growth and viability of PL-10 vaname shrimp (Litopenaeus vannamei) fry at different stocking densities. This study used a completely randomized design (CRD). There were 4 treatments, namely P1 with a stocking density of 75 heads / 40 liters, P2 with a stocking density of 150 heads / 40 liters, P3 with a stocking density of 225 heads / 40 liters, and P4 with a stocking density of 300 heads / 40 liters, respectively. 4 repetitions. The research data were analyzed using statistical analysis Univariate One Way Analysis of Variance at 5% level with a 95% confidence interval. The results showed that the highest daily growth rate was obtained in treatment P1 with an average value of 26.836 ± 0.745% / day, the highest daily length growth rate was obtained in treatment P1 with an average value of 6.719 ± 0.103% / day, the highest absolute weight growth was obtained at treatment P1. P1 treatment with an average value of 0.031 ± 0.027 gram, absolute length growth was obtained in treatment P1 with an average value of 23.025 ± 0.667 mm, the highest survival rate was obtained in treatment P2 with an average value of 96.333 ± 3.549%, but not different real with treatment P2 (93.333 ± 3.443%) and treatment P4 (92.417 ± 2.062). The conclusion of this study is that stocking density has a significant effect on the growth of vannamei shrimp which are being maintained at the PL-10 stage. The best stocking density in this study was P1 treatment (75 fish / 40 liters)

DISTRIBUTION AND ESTIMATION OF HEAVY METAL (PB) CONTAMINATION LEVELS IN THE WATER AND SEDIMENT BONDET ESTUARY, CIREBON
Get PDFThe water and sediment caused by heavy metal has become a major problem in coastal areas. Heavy metals released into the water binds to particulate matter, accumulate into sediments and its predicted by the pollution assessment method. The aims of this research was to investigate the distribution and contamination levels of Pb in water and sediments of Bondet Estuary. Water and sediments samples were collected from four stations in September 2020. The monitoring data of water quality status, contamination factor (CF), and geo-accumulation index (Igeo) were used to provide a assessment of the Pb contamination. The concentration of Pb in water at all stations (0,024-0,031 mg/L) was higher than the standard surface water, with the status is lightly polluted (class B). CF index for all stations 1 ≤ CF <3 indicates moderate Pb contamination in the sediment, while Igeo for each station is <0, which means no contamination. Overall when referring to some guidelines for sediment standards, Pb concentrations at all stations were still below the standard value for sediment. This study provides a basis for assessing future conditions and risks, so that it can contribute to the management and evaluation of heavy metal contamination in the Bondet Estuary

No full textThe study was conducted between February and June 2020. The pesence of local institution, which is responsible for marine and fisheries resource management known as “Kawasan Kelola Laut (KKL*)”, was the main reason why the study was carried out in Saponda Island. The objective of the study was to assess communtity preception on the presence of KKL*. Cluster random sampling method was selected by involving 94 respondents as representative of the perception. Principal component analysis (PCA) was selected, through which the relation between each respondent charateristic and level of perception was indentified. Result showed that respondent perception had positively correlated to meeting frequency (r = 0.67). the higher frequency of participant attended either formal or non-formal meeting, the better community perception would be formed. It was estimated thar respondent received more information and socializaton on the essential of KKL* during the meeting.Keywords: Perception, Kawasan Kelola Laut, Saponda Islan
