Abstract

Abstract Feed plays an important role in fish farming activities. Meeting the needs of feed quality and quantity sufficient aims to increase farming production, in addition to the feed given to fish properly assessed not only from the composition of the feed but also of how much the components contained in the feed can be absorbed and utilized by the fish in his life. Factors that may affect the digestibility of feed include feed composition, range and quality of the enzyme in the intestine or the stomach of fish (NRC, 1993) while Mudjiman (2002) states that the specific differences in the digestive system in fish can lead to differences in the ability of fish to digest feed, for it is used in this study true stomach fish and stomachless fish. This study aims to determine whether there are differences in the digestibility of crude fiber and determine the optimum content in true stomach fish and stomachless fish. The study design used in this study was Complete Randomized Design (CRD) factorial pattern with two factors, factor A is a type of fish and factor B is the type of feed. Analysis of the data were processed using Analysis of Variance (ANOVA) to determine whether there is an interaction effect between the treatment given. If there is a difference in the effect of test distance followed by Multiple Duncan (Duncan's Multiple Range Test). Based on the research results showed that there is a very real difference (p<0.01) on the digestibility of fish and feed efficiency in true stomach fish and stomachless fish. The highest digestibility resulting in treatment A2 (81,26%) while for fish feed efficiency, the true stomach fish has a higher feed efficiency than the stomachless fish is 20,91%.

Abstract

AbstractGracilaria cultivation is basically in need of lighting for photosynthesis process which will be a great effect on growth. The use of fluorescent (FL) as a replacement for the sun light is used for fluorescent lamps produce white light, except that fluorescent lights do not increase the room temperature drastically culture (temperature stable) and the intensity of light produced in the culture room suitable for the growth of shoots Gracilaria verrucosa. In addition to light intensity, while irradiation also affects the growth of cultured algae. Long exposures are generally set according to the needs of algae in natural conditions. In the process of photosynthesis is need a light and dark reaction. Light reaction occurs in the conversion of light energy into chemical energy and dark reactions occur for the formation of glucose that used for catabolism system. This study aims to determine the best long exposures of the different long exposures which can affect the growth and the amount of chlorophyll a of G. verrucosa. The methods is an experimental that used Complete Random Design (RAL) as the experimental design. The treatment used is different irradiation time, the treatment A (long irradiation for 24 hours, control), treatment B (irradiation time 12 hours light: 12 hours dark), treatment C (irradiation time 8 hours light: 16 hours dark) and D treatment (irradiation time 16 hours light: 8 hours dark) of each treatment is repeated five times. The main parameters were observed daily growth rate (%/day) and the amount of chlorophyll a (µg/ml) of G. verrucosa. Supporting the observed parameters are pH, temperature (ºC) and salinity (%o) The analysis data is using of variants analysis (ANOVA), if there is a difference data followed by Duncan's Multiple Range Test to determine the best treatment. The results showed that different irradiation time take a real effect (P <0.05) on the growth and the amount of chlorophyll a G. verrucosa.

Abstract

Abstract Gracilaria verrucosa is one of the most potential seaweed and consist of a high economy value. G. verrucosa had been succed cultivated in pond and it produces gel (Lewmanomont, 1995). Gracilaria cultivation in pond generally needs a wide area, easily infected by moss and shellfish so that obstructs Gracilaria's growth, even decreases it's quality (Aslan, 1998). One of the solution to solve the problem above is cultivate another seaweed G. verrucosa indoor using the combination of NPK and TSP. NPK and TSP are used to increase growth and formation of chlorophyll a which used to fotosintesis process (Anggadiredja dkk., 2006). The absortion of hara element will add nutrient and influenced to the G. verrucosa's quality and quantity. This research uses water concentration measuring because gel content measuring is relatively expensive. The goal of this research is knowing the influence of NPK and TSP to G. verrucosa's growth, water concentration and quantity of chlorophyll a. The result of G. verrocosa shows that daily growth heavy of G. verrocosa in D treatment extremely different (p<0,05) with A, B, C, E and F treatments. The best daily growth heavy of G. verrocosa is in D treatment and the lowest daily growth heavy of G. verrocosa is in A treatment. The result growth length shows that in D treatment extremely different (p<0,05) with A, B, C, E and F treatment. The best growth length is in D treatment and the lowest growth length is in A treatment. The result G. verrucosa's water concentration shows that in C, D and E treatment extremely different (p<0,05) with A, B and F treatment. The best water concentration is in C, D and E treatment. The lowest water concentration is in A, B and F treatment. The result chlorophyll a quantity shows that in B, C, D E and F treatment extremely different (p<0,05) with A treatment. The best G. verrucosa's chlorophyll a quantity is in B, C, D, E and F treatment. The lowest G. verrucosa's chlorophyll a quantity is in A treatment. The conclusion of this research is the combination of NPK and TSP in G. verrucosa seaweed cultivation extremely affect the growth, water concentration and chlorophyll a G. verrucosa with the best dose is 2 g/l and the ratio NPK and TSP is 50%:50%.

Abstract

Abstract The higher toxicity of α-linolenic acid from Ulva sp. seaweed showed the high algicidal activity against Chattonella marina and Heterosigma akashiwo. Among six species tested, C. marina and H. akashiwo was the most susceptible to this fatty acid, whereas LC50 of α-linolenic acid was estimated to be 3.22 and 0.58 µg/mL, respectively. Furthermore, α-linolenic acid also showed algicidal activity against Alexandrium tamarense and A. taylori. It is suggested that α-linolenic acid is useful mitigation agents to Harmful Algal Bloom effect, especially on Chattonella marina and Heterosigma akashiwo.

Abstract

Highlight Research Experimental use of pre-treated pangasius skin as collagen raw material using different acetic acid immersion time Effects of immersion time on the yield of collagen from pangasius skin Effects of immersion time on the proximate content of collagen from pangasius skin Presenting SDS-Page profile of collagen from pangasius skin   Abstract Pangasius sp. production in Indonesia has reached 384,310 tons in 2019. One of the main waste in pangasius fillet industry is the skin, which reached to 6% of body mass. Fish skins are alternative for making collagen because it has no restrictions for certain religions and ethnicities. Collagen is a protein biomaterial which acts as the main component of connective tissue. Extracting collagen using organic acids such as acetic acid is the most common extraction method. Herein, we report the effects of different immersion time of acetic acid to collagen properties from pangasius skin. In this study, pangasius skin was treated using 10% alcohol with the ratio 1:10 (w/v) for defatting and 0.1M NaOH with the ratio 1:10 (w/v) for eliminating non-collagenous protein. The immersion of 0.5M acetic acid was carried out on pangasius skin with the ratio of 1:20 (w/v), for 24, 48, and 72h at temperature less than 15oC. The sample was salted-out for 24 hours with NaCl until the concentration reached 2.5M, then the sample was freeze-dried at -40oC. This study investigated that longer immersion time affected the properties of pangasius skin collagen. Different immersion time significantly affected the yield of collagen from pangasius skin (p<0.05). Pangasius skin has a potential to be used as collagen raw material, and 72h of immersion time (P3) is suggested to produce pangasius skin collagen with the highest yield and protein content (6.15 % and 9.26 %). Production of collagen from the fish skin will contribute to increase pangasius waste valorization in pharmaceutical industry.

Abstract

Lemuru fish (Sardinella lemuru) is rich in omega-3 so it is widely used as raw material for fisheries production such as fish canning which produces by-products in the form of crude fish oil which needs to be purified by adding adsorbents so that it becomes pure fish oil. The adsorbent that can be used in the purification of fish oil is activated charcoal. Fish oil can be used as raw material for making added value products such as margarine. The aim of this study is to analyse the characteristics of margarine as a value-added product made from fish oil. Research shows that purification with activated charcoal produces fish oil with %FFA and PV that are in accordance with IFOS. Fish oil margarine in this study showed organoleptic value of colour 7.4 and aroma 7.07, emulsion stability 100%, %FFA content 0.28 ± 0.08, PV 1.6 ± 0.173, and higher 0.39% EPA and 2.58% DHA content compared to commercial margarine. In previous study showed margarin from sardine fish oil contains 19.5% EPA and 10.5% DHA which is also not found in commercial margarine from palm oil. The difference in EPA and DHA content between this study and previous study may be due to the fact that the fish oil in this study was obtained from by-products of canning processing with high temperatures which may cause a decrease in fatty acid levels due to protein denaturation.
