Abstract

The use of seaweed in various industries is currently increasingly widespread. This makes the need for seaweed as a raw material increasingly increasing, apart from that the international market is also aggressively receiving seaweed from Indonesia. Southeast Maluku and the city of Tual have sufficient grass potential available. Nutmeg is a local fruit that is often found in the Maluku area. Kur District is one of the sub-districts of Tual City, which has quite abundant nutmeg plantations. So far, people only use mace and seeds, while the flesh is thrown away, even though the flesh is the largest component of nutmeg, namely 1:4. Jelly drink is a gel-shaped drink that is easy to suck, chewy and can be consumed as a hunger quencher. Gels can be formed through the mechanism of junction zone formation by hydrocolloids (such as carrageenan) together with sugar and acid. This drink has a viscosity level between fruit juice and jelly (Zega, 2010). Jelly drinks can be useful for improving digestion because this product contains fiber so it can also be categorized as a functional drink. Jelly drinks can be given additional ingredients containing vitamins to increase their nutritional value (Sudirjo and Ohoiwutun, 2015). The addition of nutmeg juice to jelly drinks has never been done. This research aims to determine the level of consumer acceptance of seaweed (E. cottonii) jelly drink with added nutmeg juice (Myristica fragrans Houtt). The research was conducted in December 2022 - January 2023, at the Fisheries Product Processing Laboratory, Tual State Fisheries Polytechnic. The ingredients used are dried E. cottonii seaweed and fresh nutmeg, as well as additional granulated sugar. The results showed that the addition of nutmeg juice with a concentration of 20% was preferred by the panelists, both in terms of appearance, color, texture, smell and taste parameters.

Abstract

The high market demand for nilem fish must be balanced with good hatcheries. One of the success factors of hatcheries is the hatchability of fish eggs. Egg hatchability is the percentage of eggs that hatch after a certain time. The hatchability of fish eggs is certainly influenced by several factors, one of which is pH which affects the chorionase enzyme in eggs. The purpose of this study was to determine the effect of different pH in the media on the hatching of nilem fish eggs. The research method used is an experimental method with a complete randomized design (RAL). The mainmain parameters used in this study are embryo development, hatching rate (HR), larval abnormality, and larval survivale (SR) and the supporting parameters used in this study are temperature and DO. The results showed that pH treatment had a significantly different effect on the hatching of nilem fish eggs. The best result of HR in nilem fish was 95% at pH (9) and the lowest result of HR in nilem fish was 15% pH (11). The hatchability relationship of eggs given different treatments formed a quadratic equation. The results showed that pH treatment affects the SR value. The best SR result of nilemfish larvae was 93% at pH (9) and the lowest SR result was 0% at pH (11). The survivale rate relationship of eggs given different treatments formed a quadratic equation.

Abstract

Skin of Nipah fruit (Nypa fruticans) contains cellulose, hemicellulose and lignin compounds, so it has the potential to be used as raw material for making liquid smoke. The urgency of this research is that until now the use of palm fruit skin to make liquid smoke is still very rare or non-existent. This research aims to characterize the contents of liquid smoke from Nipah fruit skin and determine its potential as an antibacterial against Staphylococcus aureus bacteria. The research stages were divided into 3 stages, namely the liquid smoke production stage, the liquid smoke characterization stage and its antibacterial potential, and the data processing stage. The data obtained was analyzed comparatively descriptively. The research results showed that the compounds contained in liquid smoke included total acids (as acetic acid), total phenolics and carbonyls. With the compounds contained and its acidic pH value, liquid smoke from Nipah fruit peel (Nypa fruticans) has very strong antibacterial capabilities at a concentration of 100%. Thus, this liquid smoke has the potential to be used as an antibacterial agent against Staphylococcus aureus bacteria

Abstract

Ornamental fish is a type of fish that lives in fresh water or in the sea that has a beautiful and attractive body shape or color. One type of freshwater ornamental fish that has a unique difference from the others is Betta ornamental fish. Betta fish is one type of ornamental fish that is in demand by the public, but the breeders of this betta fish are mostly confused about how to increase the brightness of the color of betta fish. Based on this background, this study aims to determine the effect of adding carrot flour with different concentrations in commercial feed on the color intensity of halfmoon betta fish (Betta splendens).This study used an experimental method with a Complete Randomized Design (RAL) of 4 treatments and 3 repeats. Then the variables observed include, fish brightness, fish weight, fish length, fish daily length, fish survival, and water quality. Furthermore, the observed data and data processing is carried out with SPSS statistical software 25.The addition of carrot flour in commercial feed can affect markedly (P>0.05). The addition of P4 treatment carrot flour at a dose of 95% pellets and 15% carrot flour in commercial feed, gave good results on the brightness of the color of Betta fish with an average value of 5.0 compared to other treatments that were given the addition of less carrot flour.

Abstract

Indonesia produces 64 million tons of plastic waste every year and 3.2 million tons of it is thrown into the sea, so research needs to be done to create plastic that is environmentally friendly and easily decomposed (bioplastic). Alginate and carrageenan are polysaccharides produced from seaweed which have potential as materials for making bioplastics. This research aims to determine the effect of alginate and carrageenan on the quality, physical properties, mechanical properties and biodegradability of carrageenan-chitosan bioplastics with glycerol plasticizer. Carrageenan is obtained from extraction of Kappaphycus sp. who comes from the Yapen Islands, Papua Province. Making a carrageenan bioplastic solution by dissolving carrageenan flour (1; 1.5; 2; 2.5 grams) and 5 ml of glycerol in 100 ml volume of vingga distilled water then heating using a magnetic stirrer for 15 minutes at 90oC. The process of making a chitosan solution is by dissolving 2 grams of chitosan, 3 ml of glycerol, and 1 ml of glacial acetic acid in 94 ml of distilled water then heating with a magnetic stirrer for 10 minutes. The research results show that. The best concentration of carrageenan in the alginate-carrageenan composite bioplastic is 1.5 grams because it has physical and mechanical properties that meet the Japanese Industrial Standard and SNI 7188.7:2016 except for water resistance.

Abstract

Toxicity is the ability of a substance or chemical which, when exposed for a certain period, can cause damage to organisms. Factors that influence toxicity are composition, type, duration and frequency of exposure, recipient biota species and environmental characteristics. The results of this test describe the values LC50-96 hours or LC50-48 hours. The LC50 value is the concentration at which the extract solution can cause population death of up to 50%. This study aims to determine the concentration of acute toxicity of liquid palm oil waste on tilapia fish seeds and its effect on the organoleptic properties of tilapia. This research was carried out from May to July 2023 at the Aquatic Resources Management Laboratory, Faculty of Agriculture, Tanjungpura University. The method used is a static method in acute toxicity tests to determine the death of 50% of the number of test organisms. This research was carried out in 4 stages, namely preparation, preliminary test, toxicity test and treatment test. The toxicity test data was then analyzed using probit analysis. The LC50-96 hours value of palm oil liquid waste for the tilapia fish seed biota test is 4.88 mg/l. The LC50-96 hours value obtained from probit analysis is used to determine the TUa (Toxicity Unit Area) value by converting the LC50-96 hours value. The TUa value obtained was 20,49 indicating that the acute toxicity level of liquid palm oil waste causes acute toxicity.
