Abstract

Rubber cassava root (Manihot glaziovii) bark contains an active substance known as Hydrogen Cyanide (HCN), which is toxic to red-blooded animals. This bark is abundant and readily available in the community’s surroundings. Therefore, this research aims to investigate the effect of using rubber cassava root bark at specific doses in eradicating red-blooded fish. The test animals used are Nile tilapia (Oreochromis niloticus). Each treatment is repeated three times and assigned specific codes: code A as a control with the application of 20 ppm saponin, and codes B, C, and D with the application of rubber cassava root bark liquid at 20 ppm, 40 ppm, and 100 ppm, respectively. The parameter used as the observation criterion is the mortality rate of the test animals over 6 hours with varying doses of rubber cassava root bark liquid. Based on the research results, it can be concluded that rubber cassava root bark liquid can be used as an alternative to replace saponin at 100 ppm. Further research is required to determine the most effective dose of rubber cassava root bark as a substitute for saponin in aquaculture.

Abstract

Surimi is Japanese, meaning crushed meat. To encourage fish consumption, products made from processed surimi are made more varied and interesting, such as fish dumplings. This research aimed to determine the differences in the sensory characteristics of surimi from different raw materials (swangi fish, kurisi fish, and kuniran fish). Apart from that, we also want to know the organoleptic and hedonic test results of fish dumplings made from different surimi raw materials. The surimi testing method includes an appearance test, folding test, and bite test on three different types of surimi (SU1 = kurisi fish, SU2 = swangi fish, SU3 = kuniran fish). Organoleptic and hedonic test methods for fish dumplings include appearance, smell, taste, and texture. The research results showed that there was a significant difference in the physical test of surimi (fold and bite test), while in the appearance test, there was no real difference. The surimi organoleptic test showed that there was no difference in smell and taste, while there were different results in appearance and texture parameters. The results of the hedonic test showed that panelists preferred sample SU1 on appearance and smell parameters, SU2 was preferred on taste parameters, and SU3 was superior on texture parameters.

Abstract

There are several types of purse seine in Sibolga, namely tuna trawls, snare seines and meeting trawls. The main catch from purse seine is pelagic fish. Purse seine catches are related to the mesh size of the fishing gear. The mesh size is small so it can catch more than 3 species of catch which are classified as non-environmentally friendly fishing gear. The aim of this research is to find out whether purse seine fishing gear in Sibolga is environmentally friendly fishing gear or not. The research was conducted March 1 – June 30 2021 at the Sibolga Fishing Port (PPN), The research was carried out at KM Samosir 08 on cob trawl fishing gear and KM Serasi Putra on cob trawl fishing gear. The data analysis used is a scoring analysis of environmentally friendly fishing gear criteria. Trawls and cob trawls are environmentally friendly fishing gear and meet the 9 criteria for environmentally friendly fishing gear. The score for the level of environmental friendliness of the tuna trawl fishing gear was 33 and the meeting trawl was 32.6 with the criteria being included in the group of very environmentally friendly fishing gear.

Abstract

Mussel shells are shellfish that live in freshwater and have two parts, namely the meat which is used in food and the shell which is still underutilized. Mussel shells (P. exilis) contain calcium and phosphate compounds that have the potential as hydroxyapatite. Hydroxyapatite is the main mineral component of teeth and bones. This study aimed to determine the hydroxyapatite characteristics of mussel (P. exilis) shells. The method in this study was an experiment with a calcination temperature of 700°C which was repeated 3 times and went through 3 stages including 1) sample preparation, 2) calcium oxide powder (CaO) extraction, and 3) hydroxyapatite synthesis with test parameters consisting of yield analysis, Ca and P levels, and functional groups. The hydroxyapatite characteristics of mussel shells were yield of 6.69%; Ca content of 50.13%; P content of 1.60%; hydroxyl groups were detected at wave number 3641.76 cm-1 and 3570.39 cm-1; phosphate group at wave number  1033.89 cm-1;  and carbonate group at wave number 1457.28 cm-1; 1448.60 cm-1 and 1419.67 cm-1.

Abstract

Incentive shrimp farming system has become a farming system adopted by most Indonesian farmers to rapidly increase pond productivity with high stocking densities ranging from 100-300 fish/m2. The study aimed to determine the growth performance and survival rate of Vannamei shrimp culture at PT Andulang Shrimp Farm, Sumenep, East Java with different plot sizes and stocking densities. In the augmentation method, 2 culture plots are used, each with an area of plot D4 (1,932 m2) with a stocking density of 177 fish/m2 and plot F3 (2,600 m2) with a stocking density of 172 fish/m2. In plot D4, the average body weight (ABW) was 26.45 g, the feed conversion ratio (FCR) was 1.63 and the survival rate (SR) was 74.05% with a total harvest tonnage of 4,845.64 kg. In plot F3, the average body weight (ABW) was 26.36 g, the FCR was 1.61 and the SR was 75.42% with a total yield of 6,674.42 kg. A high protein diet contributes to the growth of Vannamei shrimp. Optimal water quality and proper feeding can promote the growth of Vannamei shrimp.

Abstract

Pyrolysator performance testing has been carried out on the results of liquid smoke produced by pyrolysators with a multilevel condensation system using coconut shell fumes. The parameters tested in the pyrolysator performance test were time, temperature, heating rate, volume of liquid smoke and residual combustion in the form of charcoal. Test results using Gas Chromatography-Mass Spectrophotometry (GC-MS) show that pyrolysators with multilevel condensation systems produce liquid smoke with food grade quality so it is safe to use as a natural preservative for fishery products. The amount of liquid smoke produced by the pyrolysator with a multilevel condensation system is 24% and charcoal is 46%, from the pyrolysis process of 10kg of coconut shells for 5 hours. It can be concluded that pyrolysators with multilevel condensation systems have advantages in terms of productivity when compared to conventional pyrolysators, so they are very suitable for use in the liquid smoke industry.

Abstract

Ocean currents are the movement of sea water masses in a certain direction caused by several factors, namely wind, tides and bathymetry. Hydrodynamic modeling aims to determine the speed and direction of ocean currents in the waters of Bakau Bay through a two-dimensional model. The current pattern of the north season to the east season is influenced by sea water masses with an average current speed ranging from 0.22-0.24 m/s, while the south season to West season currents with an average speed of 0.04-0.26 m/s, this shows the meeting of different water masses so that the speed and direction of the current results in random or rotating currents. From the calculations of the normality test and anova test, it is known that the field current and model simulation values are normally distributed and there is no significant difference in values in the two data, so based on the RMSE value, it shows that the difference in values between the model simulation results and direct data measurements is relatively small. This also shows that the ocean surface current model created is sufficient to describe actual conditions.

Abstract

Pole and line is one of the most dominant fishing tools at the Bitung Ocean Fishing Port. The aim of this research is to determine the risk of work accidents when operating pole and line fishing gear. The data used in the research was taken by direct observation in the field and using the HTA (Hierachical Task Analysis) method. This method is used to find out all the activity processes of a job, in order to know the sub-activities when operating pole and line fishing gear. The risk of work accidents that can occur when operating pole and line fishing equipment is in the low risk and medium risk categories. Activities that have low risk are 9 activities with a percentage of 75% including activities: 1) ship leaning against a floating chart, crew members walking on a floating chart, 2) putting fish (bait) into cans, 3) putting fish (bait) into hatch, 4) paying for bait, 5) crew turning on the water pump, 6) crew preparing for fishing, 7) watering caught fish, 8) putting fish into the hold, 9) giving ice to the fish. There are 3 medium risk activities with a percentage of 25%, the activities include: 1) buoys spreading live bait on the sea surface, 2) fishing line withdrawal, 3) fishing line lowering. There were no high risk activities found in the operation of pole and line fishing gear.
