Abstract

White shrimp (Litopenaeus vannamei) culture has grown rapidly in Indonesia since  early 2000s. White shrimp have stronger resistance to WSSDV attacks, and are euryhaline. In it’s natural habitat, this shrimp was found in waters with a range of 0.5-40 ppt salinity. White shrimp grow optimally at 15-25 ppt salinity, even still suitable at 5 ppt salinity. This capability provides the opportunities to culture these commodities in inland water. White shrimp need inorganic elements or minerals for their living processes. Calcium is one of the main needs of shrimp that is closely related to the development and maintenance of skeletal systems and plays a role in some physiological processes of the body.The requirement for calcium in shrimp is increasing when it is cultivated in fresh water.This Internship aims to find out the technique of adding calcium carbonate (CaCO3) in feed, used for the white shrimp culture in fresh water. In this field practice, the addition of calcium carbonate in a level of 2% refers to the requirement of white shrimp for optimal growth. This was based on the calcium requirements of shrimp in the amount of 1-2%. The method was repelleting, by grinding feed and calcium using mortar and pestle, then filtered to get the smoothest part. Then mix calcium with 10 mL of water and mix it with pellets evenly. Then the mixture is air dried and mashed again and weighed according to the required dose of feed. The addition of calcium in the feed affects the growth of shrimp, because calcium is one of the most important anorganic mineral for the growth and development of exoskeleton, regulates blood clotting, heart rate, kidneys, nerves, the activity of several enzymes, and cell function

Abstract

Fish is a protein source that is very potential and needed by humans. One of the fish that has a high enough nutrient content is Red Snapper (Lutjanus malabaricus). Snapper fish contains 92 kilocalories of energy, 20 grams of protein, 0 grams of carbohydrates, 0.7 grams of fat, 20 milligrams of calcium, 200 milligrams of phosphorus, and 1 milligram of iron. The high water content is one potential that must be considered because it is a good medium for microbial growth. Therefore efforts are needed to maintain the nutritional content, freshness, taste, and extend the shelf life through preservation, one of which is by freezing. The Air Blast Freezing method is one of the freezing methods that uses a combination of low temperatures which are temperatures of -35℃ to -40℃ by blowing cold air  quickly towards the product. This method has the advantage of one of which is relatively easy operation. The purpose of this field work practice is to know the process of freezing Red Snapper (Lutjanus malabaricus) with the Air Blast Freezing (ABF) method and the obstacles in the production of Red Snapper (Lutjanus malabaricus) using the Air Blast Freezing (ABF) method. The stages of the production process of Red Snapper (Lutjanus malabaricus) are the reception of raw materials, washing I, sorting, washing II, weighing, washing III, preparation, freezing with the Air Blast Freezing (ABF) method, glazing, packaging, storaging, stuffing. The freezing process with the Air Blast Freezing (ABF) method uses a temperature of -35℃ to -40℃ for 6-8 hours so that the plant can produce as much as 3 tons in one day. Obstacles to the freezing process at PT ILUFA are raw materials that contain parasites. Factors that influence the freezing process include raw materials during the reception and monitoring process during the freezing process in the ABF engine.

Abstract

Hairtail fish (Trichiurus savala) is potential to have a rapid deterioration due to the high water and protein content in the body of the fish. One of the efforts to prevent or slow down the deterioration of layur fish is by freezing treatment. The freezing process also cannot be completely avoided from the emergence of potential hazards, therefore a way to prevent or suppress potential hazards is needed by applying the Critical Control Point (CCP). The descriptive method with data collection including primary and secondary data was used in this study. The freezing process of layur fish at PT Pan Putra Samudra starts from receiving, sorting, weighting, labelling, washing, wrapping with plastic and arranging in cartons, freezing, packaging, and frozen storage. The stages determined as CCP in the freezing of layur fish are in the sorting stage. At the sorting stage, quality checking is performed including organoleptic and microbiological tests. It also checks physical hazards such as hooks and nets. The sorting stage is determined as CCP because in the next stage it cannot prevent or reduce the potential danger that exists in fish. Fish that have gone through quality checking and exceeding the threshold will be put in a special fish reject basket.

Abstract

Eel (Anguilla sp.) is a fish that is classified as having a high economic value, with the level of distribution in almost all of Indonesia. The Timang Tideng River is one of the rivers located in the village of Kamaifui, Alor Regency, but until now, there has been no scientific report on the distribution of eel (Anguilla sp.) in the Timang Tideng River, Alor Regency, NTT. This study aims to determine the type and size of eel found in the Timang Tideng River. The research was conducted from March to April 2021 at three observation stations. Eel fishing is done at night considering its nocturnal nature. The fishing gear used is fishing rods and chicken stomachs as bait. Measurements of physical and chemical parameters of the waters were carried out simultaneously during the fishing process including temperature, pH, and current speed. The results showed that there were two types of eel in the Timang Tideng River, namely A. marmorata as many as 24 individuals and A. celebesensis as many as 1 individual. The eels found were in the yellow eel phase, with a total length range of 40-72 cm and a total weight ranging from 126-994 g.

Abstract

Green mussel (Perna viridis) is a fishery food that is often consumed by the community because the price is relatively affordable. This animal has the potential to be used because it has a large population, but one of the problems in Indonesian waters, especially Kenjeran Beach, is that it contains Pb metal. Consuming green mussels with Pb levels will interfere with body health, so it is necessary to take action to reduce the Pb metal content in green mussels, one of which is using citric acid. The purpose of this study was to determine the effect of soaking green mussel meat in citric acid with different concentrations on the reduction of Pb heavy metal levels. This research is a laboratory experimental with a Completely Randomized Design (CRD) consisting of 4 different treatments of immersion concentration in citric acid (0 , 0.21 , 0.25 and 0.29 M). The results showed that the immersion of green mussel meat in citric acid with concentrations of 0.21 , 0.25 and 0.29 M had a significant effect on the reduction of heavy metal lead (Pb) after immersion in citric acid at a concentration of 0.29 M is 0.1120 ppm, 0.25 M is 0.1167 ppm and 0.21 M is 0.1160 ppm. Soaking green mussels in citric acid with different concentrations did not affect the yield value of green mussel meat.

Abstract

Chitosan is a biopolymer that can be extracted from crustaceans, such as shrimp shells. Chitosan is widely used in various fields, such as pharmaceuticals, food, and cosmetics because it is biodegradable, non-toxic, and has antibacterial activity. Nanochitosan is a dosage form based on nanotechnology which has more reactive properties. The purpose of this study was to characterize chitosan and nanochitosan and evaluate the effectiveness of nanochitosan as an antibacterial in hand sanitizer. The tests carried out included analysis of the functional group of chitosan with FTIR, particle size analysis with particle size analyzer, morphological analysis of nanochitosan with SEM, and analysis of the effectiveness of hand sanitizers. The test chitosan used had a degree of deacetylation of 85.94%. The particle size distribution of nanochitosan was 140.94 nm with a polydispersion intensity (PDI) of 0.5830. The results of the antibacterial effectiveness test of nanochitosan as a hand sanitizer showed that the higher the concentration of nanochitosan used, the total bacterial colonies would decrease. The concentration of 2000 ppm nanochitosan can reduce 93.4% of bacterial colonies on probandus hands, and this activity is known to be not significantly different from commercial hand sanitizers.
