Abstract

This research was conducted in Muara Nibung Village, Pandan District, Central Tapanuli Regency, North Sumatra Province with the aim of knowing the amount of investment, profits, and the level of feasibility of fishing for a tancap fisherman based on financial (financial) aspects using investment analysis, income, profit, revenue cost (R/C), financial rate of return (FRR), and payback period of capital (PPC). The method used in this study is a survey method while the determination of respondents is carried out by census. Data collection was carried out by observation, interviews, and documentation directly with 37 people of bagan tancap fishermen. The results of the study show that the step-by-step chart in Muara Nibung has two categories of operating distance from the coast, including the near chart ±1 km and the far chart ±3 km, of course, different investments, profit, and business feasibility. For charts close to ±1 km the total investment is (Rp124.616.000,00), the profit received is (Rp121,240,800.00/year), R/C (2.59), FRR (97.29), PPC (1.03). Whereas Forfar chart ±3 km the total investment is (Rp139,416,000.00), the profit received is (Rp179,140,800.00/year), R/C(2.85), FRR (128.49), PPC (0.78). Based on the results of the calculation that the R/C is more than 1, the FRR is greater than the bank interest rate of 11%, and the PPC is getting smaller, meaning that the fishing business is profitable and feasible to continue

Abstract

Anchovies (Stolephorus sp) are fish that have important economic value even though they are small. This fish is rich in nutritional content and has a savory and delicious taste when processed into food. This fish is very liked by various groups even though it has small in size and without bones. This anchovy contains lots of calcium, protein, and minerals such as phosphorus and iron that are very useful for increasing the intelligence of children and toddlers, as well as for preventing osteoporosis in pregnant women and the elderly as well as helping in the growth of bones and teeth in infants, toddlers, and children. To improve the quality of anchovy nuggets, it is necessary to add certain binders to improve the taste of anchovy nuggets. This study aims to improve the quality of anchovy nuggets by adding a binder in the form of sajiku flour and adding to the economic value of refined anchovy so that it is more attractive to the public. There were 3 treatments and 2 repetitions. The treatments were A. Anchovies; A1 = using carrots, A2 = without carrots, and treatment B (my flour concentration); B1=100g, B2= 200g. Moreover, Treatment C (cooking temperature); C = 65ºC - 85ºC for 30 minutes. From the results of the study, it can be seen that the water content, protein content, and fat content did not show any significant effect

Abstract

Freshwater lobster (Cherax quadricarinatus) is a type of crustacean (crustacean). Freshwater lobster is a type of shrimp that lives in shallow fresh inland waters, with a muddy substrate and lots of gaps and cavities to hide. The cultivation of freshwater lobsters is quite easy because the tolerance to the environment is quite high with relatively few disease problems. Molting is a natural process that occurs in freshwater lobsters as their bodies grow. Calcium is one of the mineral elements that lobsters really need to form new shells. In addition to calcium, lobsters will also undergo a mineralization process to form new membranes using calcium absorbed from the environment in which they live. The purpose of this study was to determine the effect of supplementation of calcium flour from crab shells on commercial feed on molting frequency, absolute weight and length, survival of freshwater lobster, and determine the appropriate dose of calcium flour supplementation of crab shells. This study used a completely randomized design (CRD) with 4 treatments and 4 replications with additional doses of calcium flour, 0%, 2%, 4%, and 6% per kg of feed. The stock density of freshwater lobster was 7 individuals per aquarium for 30 days of rearing. The results showed that the addition of shell calcium powder of as much as 4% (treatment C) was the best dose with 2 molts/ind and the lowest was in treatment A (control). The highest growth in absolute weight and absolute length was at a concentration of 4% (treatment C) 2.34g and 1.55 cm, the lowest value was obtained at treatment A (control) 1.63g and 0.95 cm. Supplementation of crab shell calcium flour in commercial feed for crayfish did not have a significant effect on the survival (SR) of freshwater lobster

Abstract

Eichornia crassipes have root fibers that can repair water quality, improve the concentration of chlorophyll-a, increase growth, and maintain the survival of local catfish. The purpose of this study was to obtain the best biomass of water hyacinth for the increasing concentration of chlorophyll-a on local catfish rearing in August – September 2020. This study used a one-factor completely randomized design (CRD) with 4 treatments and 3 replication. The treatments in this study had different water hyacinth biomass, P0 (Control), P1 (112 g m-2), P2 (162 g m-2), and P3 (212 g m-2). The local catfish seeds that are used are sized approximately 5-7 cm, weigh 2.62-3.02 g, maintained for 30 days in a rearing container with a peat water volume of 98 L and a density of 2 fish L-1. The result showed that the best treatment was biomass 212 g m2 water hyacinth containing concentration chlorophyll-a 0.73 µg L-1 with the value of correlation concentration chlorophyll-a (r)=0.97 and R2=0.95, it was able to improve concentration chlorophyll-a on local catfish rearing such as increasing pH 5.7-6.0, nitrate 2.45 mg L-1, phosphate 2.09 mg L-1, temperature 27-280C and dissolved oxygen 5.4-5.5 mg L-1. Absolute weight growth (9.04g) with the value of correlation (r) = 0.99 and R2 = 0.99, and survival rate of local catfish (94.67%). The highest growth of the biomass water hyacinth per 3 days is 2.82%.

Abstract

Pasumpahan Island is an area that is affected by currents, waves and sedimentation processes because it is directly adjacent to the Indian Ocean and the mouth of the Pisang River, this causes changes in the coastline in the form of abrasion and accretion on the island. This study aims to determine the effect of currents, waves, and sedimentation processes on the rate of change of the shoreline for 10 years (1991-2001) on Pasumpahan Island. This research was conducted in March 2022 on Pasumpahan Island, Padang City, West Sumatra Province. The method used is a survey method to obtain primary data including current speed, heightwaves and sediments. The study method used is a quantitative method with a multi-temporal satellite imagery approachusing the Digital Shoreline Analysis System (DSAS) software with the End Point Rate (EPR) approach. The results of the analysis of current velocity values ranged from 0.21-0.28 m/s, wave heights ranged from 0.24-0.55 m, the average diameter of the sediment ranged from 0.83-1 Φ. The results of image data processing show that there has been a change in the shoreline in the form of low category abrasion (0.4 m/year), stable (1.42 m/year), and accretion (3.07 m/year) on Pasumpahan Island

Abstract

Tsunami that swept the Tanjung Lesung coast in 2018 caused Anak Krakatau to collapse in Sunda Strait which hit the coastal areas of Banten and Lampung. Tanjung Lesung is one of the worst areas affected. Tsunami in Tanjung Lesung has taken lives, damaged infrastructure, and caused terrible natural damage. One of the damages affecting residents' lives in the Tanjung Lesung coastal community is exposure to the marine ecosystem. The main ecosystem that has the highest productivity level is the coral reef. Coral biota is the main benthic biota of reefs that are directly affected by earthquakes and tsunamis. Forms of damage to coral reef ecosystems include several coral colonies that were found broken, overturned and some died because they were covered by sediment. However, until now there has been no data on the status of coral reefs after the 2018 Sunda Strait tsunami. Therefore, researchers feel the urgency of this research is high enough to determine the condition of coral reefs after the Sunda Strait tsunami in Tanjung Lesung. There are 3 research stations for data collection before the tsunami, and we conduct research in those 3 stations again after the tsunami. Then we added 3 research stations again, so there are 6 research stations. Observation of coral reefs uses the Line Intercept Transect (LIT) method. The line transect is made by stretching a roll meter with a scale parallel to the coastline along 25 meters with three replications with an interval of about 0-5 meters between replications so the total observed transect was 75 meters. The deterioration of coral reef conditions at three research stations (1-3) proved that the tsunami waves affected the damage to coral reefs. This has an impact on the diversity of coral reef species inhabitants that have decreased. Disturbance form coral-damaged structure and composition changes of the base substrate as habitat can have an impact on reef fish and coral reef inhabitants. So that this research is expected to be a reference for policymakers in determining rehabilitation steps for areas affected by the 2018 Sunda Strait tsunami
