Abstract

ABSTRACT Pecel Lele is a deep fried Clarias sp dish. This study aims to obtain fish meal from pecel lele waste by drying, steaming and boiling methods and determine the characteristics of fish meal with the best quality. The experimental design used was a non-factorial Completely Randomized Design (CRD) with 3 replications. The treatments given are drying (L1), steaming (L2) and boiling (L3). The parameters observed were the amount of flour (yield), proximate analysis (moisture, ash, fat, protein content) and chemical analysis (Ca, Mg and Fe content). The results showed that the best pecel leleflour was found in L1 treatment (drying) with the following chemical composition: moisture, ash, protein, fat, calcium and magnesium content was 5.14%, 24.03%, 56.41%, 20.32%, 44.55% 1.43%, respectively. Keywords: Fish meal, proximate analysis, waste

Abstract

ABSTRACT Shellfish is one of the mollusks from the class of Bivalve or Pelecypods. Generally, shellfish body parts are divided into five body parts that are foot byssus, head, visceral mass, mantle and shell. The used shellfish in this research was a hairy cockle that was potential as an alternative food source. The purpose of this research was to determine the chemical content of hairy cockle meat. The used method was the experimental method with two stages consisting of the preparation of hairy cockle and the chemical analysis (moisture, ash, fat, and protein) of hairy cockle meat. Based on the results  showedthat the hairy cockle meat had nutritional content that was 79% moisture, 1.94% ash, the protein of 9.56%, and the fat of 8.66%. Keywords: Experiment, chemical content, hairy cockle (Anadara antiquata)

Abstract

ABSTRACTFish Botia is a freshwater fish that have an attractive body colors. Feeding naturallypumpkin flour feed in artificial feed aimed to improve the color quality of clown fish and how long it takes to improve the color. This research was used experimental method with quantutative approach. Research used CRD (Complete Random Design) which consists of 4 treatments with different concentration includes: P0: Positive control, P1: 10%, P2: 15%, and P3: 20%, with 3 replications in each treatments. Parameter in this research are color quality improvements, length and weight accretion.Observation data were analyzed using analysis of variance (ANAVA) α <0.05. The research result showed that feeding the pumpkin flour in artificial diet affected the color improvement of clown fish but did not affect the length and weight of clown fish. The optimal color improvement of clown fish obtained on the treatment with 15% concentration.Keywords: Clown fish, Pumpkin flour, Color quality

Abstract

AbstractMystus nigriceps commonly inhabit the Tarai River that is polluted by tofu industrial liquid waste. Low water quality may affects fish growth and that is reflected in the growth ring pattern of the otolith. A research aims to understand the pattern of otolith growth rings in the M. nigriceps was conducted in April to May 2019. The fish was captured  using a cast net, and a scoop net. There were  90 fishes captured (31 males and 59 females). The otolith were removed and shaved. The dark growth ring pattern was investigated using a binocular microscope. Results shown that the standard length of the fish ranged from    75.11 to 150.44 mm and their body weight was 3.27 to 44.82 g. The otolith length was 1.375 to 2.625 mm and its width was ranged from 0.85 to 1.375 mm. Among the fish captured, 82 of them having 1-3 dark rings, indicate that the in certain period the growth of fish in the Tarai River is hampered. The distance between the nucleus and the first dark ring was 0.25 to 0.625 mm and there was no special pattern in the formation of the first dark ring. This fact indicate that the first dark rings are formed individually and it is not formed by periodic events in fish life. The water quality parameter value are as follows, temperature 27-280C; pH 6;  DO 3.2-3.5 mg/L; and CO2 23.09-24.98 mg/L) and it is able to support the life of fish. Keywords: dark ring, growth ring pattern, sagita, catfish, polluted river

Abstract

ABSTRACTThis study was aimed to determine the effect of soaking the catfish (Pangasius hypophthalmus) meatballs into the liquid smoke on their quality of during storage in cold temperature (5±2˚C), to get the optimum concentration of the liquid smoke and to determine the shelf-life of catfish meatballs. The method used was an experimental method and composed as the Randomized Block Design (RBD). The fish meatballs were soaked ini varied concentrations of liquid smoke (0, 0.5, 1.0, 1.5, and 2.0 %) and then the products were stored and observed periodically for 5, 10, and 15 days. The parameter observed were the total number of bacteria plate count (TPC), Escherichia coli bacteria, Staphylococcus aureus bacteria, pH value and sensory evaluation (appearance, odor, taste and texture). The results showed that the use of 2% liquid smoke concentration was indicated the best treatment, as seen from lowest (total number bacteria plate count 4.5 x 104 Cfu/g, Coliformbacteria 3.00 MPN/g, negative in Escherichia colibacteria, Staphylococcus aureus 7.3x 101 Cfu/g), pH value 6.8during storage in cold temperature (5±2˚c),and the highest score of appearance 5.5 (little hole,brightless and includes in middle category) odor 5.6 ( quiickly rancid odor), taste 5.7 (quickly to acid) and texture 5.0(had incompact texture) could be stored for 10 days in cold temperatures(5±2oC).Keywords: catfish ,liquid smoke, quality, storage,

Abstract

ABSTRACTCarrying capacity is defined as the ability of aquatic enviromment to support the life organism in that area. A study aimed to asses the aquatic carrying capacity based on choloropyll-a for extensive fishing was conducted in the Bunter Lake. Carrying capacity was determined based on primary productivity using chlorophyll-a. The research  was conducted July-August 2019. There were 3 stations namely station 1 (inlet area), station 2 (in the middle of the lake) and station 3 (in the end of the lake). In each stations, there were 2 sampling sites, in the surface and 2 Secchi depth. Sampling was done 4 time, once a week. Water quality parameter measured chlorophyll-a, nitrate, phosphat, dissolved oxygen, water transparency, temperature and pH. Result shown that chlorophyll-a 10.49-10.89 µg/L, nitrate 0.043-0.080 mg/L, phosphate 0.022-0.37 mg/L, dissolved oxygen 4.32-6.59 mg/L, water transparency 77.7-85.2 cm, temperature 29.5-30.5 ºC and pH 5. The concentration of chlorophyll-a indicate that carrying capacity of the Bunter Lake for extensive fishing was 0.73 tons/year.Key Word : chlorophyll-a, carrying capacity, water quality, bunter lake, primary productivity

Abstract

ABSTRACT This study aims to determine the costs, benefits and financial analysis of payang fishing gear at KM Queen which is operated on the Padang coast of West Sumatra Province. The research was conducted in August 2018, at Padang Beach, West Padang, Padang City, West Sumatra Province. The research method used is the survey method. In this research, the collected data consists of primary data and secondary data. The primary data is obtained from direct observation of fishing activities and can also be obtained from ports and local fisheries department. Secondary data was obtained through literature studies and government agencies related to research. During the study it was known that construction of fishing gear on the coast of Padang, Padang City, West Sumatra Province was the same as other regions which had several parts in common, namely bodies, wings, bags, buoys, ballast, and rope. From the results of the financial analysis, the shore at Padang beach was obtained by Benefit Cost of Ratio of 1,07 which means that the BCR value> 1, then this fishery is worthy to continue. Financial Rate of Return is 45,08% so capital should be invested into the business so that it is more profitable. Payback Period of Capital is 2,2 meaning that the time needed by fishermen for capital returns is for 2 years2 months. Keywords: Technical Aspects; Financial Analysis; Payang Fishing Gear; Padang Beach
