The fisheries sector is one of the agricultural sub-sectors that has a role in providing food for the people of Indonesia. Consumers have behavior in purchasing fish in meeting their needs or desires to obtain a product. This study aims to analyze consumer preferences for the type of fish and the order of attributes. The method used in this research is a case study. The research location was carried out at the Muara Baru Modern Fish Market (PIM) DKI Jakarta. The data used are primary data and secondary data. The primary data collection technique used accidental sampling with a sample of 100 respondents while the secondary data were obtained from Perum Perikanan Indonesia as the manager of the Muara Baru Modern Fish Market, the Library, the Central Statistics Agency (BPS) DKI Jakarta, the National Statistics Agency (BPS). Consumer preference analysis used attitude measurement analysis measured by Chi-square and based on rank orders analysis to determine the order of attribute importance. Based on the study results, it was shown that all the attributes observed in this study were significantly different at the 95% confidence level. In contrast, the analysis of the level of importance of the attributes showed that the priority of consumers' interests in fish in the Muara Baru Modern Fish Market (PIM) was price, freshness, cleanliness, texture, and fish scent.

The low survival rate in Sumatran fish fingerlings transportation is a problem related to metabolic disturbances that cause death. The addition of nutmeg seed oil in the transportation medium is expected to reduce the rate of respiration and metabolism, so that fish mortality can be minimized. The purpose of this study was to determine the effective concentration of nutmeg seed oil to maintain the highest survival rate of Sumatran fish fry transported during treatment and to analyze its effect on induction time and recovery time. This research was carried out from January to March 2021 in the Ciparanje wet laboratory, Faculty of Fisheries and Marine Sciences, Padjadjaran University. This research was conducted experimentally using a factorial randomized group design (FRGD) consisting of two factors, namely the concentration of four levels (0.03, 0.06, 0.09 ml/L and control) and duration of three levels (3, 5, and 7 hours) which was repeated three times. This research uses a closed transportation system. Parameters observed were induction time and conscious recovery time of test fish, post-transportation and post-maintenance survival for 7 days and water quality consisting of temperature, DO, pH, and ammonia. The results showed that the effective nutmeg seed oil for the anesthesia of Sumatran fish fry transported was 0.03 ml/L with a transportation duration of 3 hours because it had an induction time of 08:07, recovery time of 02:41 and postoperative survival rate. transportation by 98.33% and post-maintenance for 7 days by 91.49%. Temperature parameters are 22.7oC, DO is ±10.3 mg/L, pH is ± 6.83 and ammonia is ±0.0010 mg/L.

The east coast of North Sumatra is part of the Malacca Strait, a highly utilized fishing area. One of the commodities that can be harvested is the Yellowstripe Scad (Selaroides leptolepis). Through oceanography parameters, specifically temperature and chlorophyll-aconcentrations, it is possible to determine optimal fishing grounds which can be used as guidelines. One of the satellites that can detect sea surface temperature (SST) and chlorophyll-a concentrations is Aqua (EOS PM),which is equipped with a Moderate Resolution Imaging Spectroradiometer (MODIS) sensor. Data on the Yellowstripe Scad (Selaroide sleptolepis) were obtained from the Belawan Ocean Fishing Port (OFP). Based on the analysis of MODIS images from the Aqua satellite, the sea surface temperature of theeast coastal waters of North Sumatra in 2012 - 2016 ranged from 29oC – 32oC with chlorophyll-a concentrations ranging from 0.19 - 5.26 mg/m³. The largest harvest occurred during the west monsoon with a value of 143.46 tons and the lowest was during the east monsoon with a value of 139.87 tons. Yellowstripe Scad harvest has a negative correlation with the sea surface temperature with a correlation value of -0.365. Chlorophyll-a concentrations and harvest amount have a positive correlation value of 0.660. Yellowstripe Scad is predicted to yield the largest harvest during the west monsoon (December-February) between the Asahan and Labuhanbatu Regencies at coordinates 2.68oN - 2.74oN and 100.37oE - 100.44oE.

The purpose of this study is to analyze the competitiveness profile of floating net cage aquaculture in Indonesia. The research was conducted in February – June 2021 at the Directorate General of Aquaculture, Ministry of Marine Affairs and Fisheries of the Republic of Indonesia. The data collection method used in this study is the literature survey method. Primary data in the form of questionnaires with expert judgment respondents as many as 13 people consisting of 11 Lecturers of the Faculty of Fisheries and Marine Sciences, Padjadjaran University, and 2 employees of the Directorate General of Aquaculture, Ministry of Marine Affairs and Fisheries of the Republic of Indonesia regarding the proportion of competitiveness of floating net cage aquaculture fisheries. Secondary data in the form of statistical data on floating net cage aquaculture in 2017 was obtained from the Directorate General of Aquaculture, Ministry of Marine Affairs and Fisheries of the Republic of Indonesia. Data analysis was carried out by using quantitative descriptive analysis. The results showed that Central Java Province which was supported by facilities and infrastructure variables, West Java Province which was supported by human resources and production variables, and North Sulawesi Province which was supported by science and technology variables were in the top three with very high competitiveness category, while the Riau Islands Province and the Bangka Belitung Islands Province are in the bottom two ranks with the low competitiveness category.

This research aims to determine the best concentration of surimi made from mackerel tuna dark muscle to produce edible film with characteristics according to JIS (Japanese Industrial Standard) and to determine the characteristics of edible film product. This research was carried out in March to April 2021 at the Fishery Product Processing Laboratory, Faculty of Fisheries and Marine Sciences, Padjadjaran University and Soil Chemistry Laboratory, Faculty of Agriculture, Padjadjaran University. The method used was experimental with Completely Randomized Design (CRD), and treatment with surimi concentration consisted of three treatments with three replications including 8%, 10% and 12%. Parameters observed were thickness, tensile strength, percent elongation and transparency. The resulting data were analyzed using ANOVA and continued with Duncan's test (α=5%). The results showed that an increase in the concentration of surimi made from dark muscle of mackerel tuna had a significant effect on thickness and percent elongation, but an increase in surimi concentration had no significant effect on tensile strength and transparency. Edible film with the addition of 8% concentration of surimi made from mackerel tuna dark muscle had the best characteristics based on the Japanese Industrial Standard (JIS) and statistical analysis, with a thickness of 0.096 mm, tensile strength 486.78 kgf/cm2 percent elongation 211.67%, transparency 5, 72 and 94.28% clarity.
