Authors: Ramadhani S N , Saputra E , Andriyono S 
Published: December 2023

Abstract
Syrup products are preferred considering the tropical climate of Indonesia. One of the mangrove fruits that can be processed into syrup is pedada (Sonneratia caseolaris) which is combined with the natural colour of roselle flower petals. With the addition of roselle, the resulting syrup colour becomes attractive with a pink color. The manufacture of roselle mangrove syrup requires the addition of the right sugar. In this study, the manufacture of 1 kg of mangrove fruit was added with 3 concentrations of sucrose sugar (1; 1.5, and 2 kg). Tests were carried out by measuring antioxidant activity, the value of sucrose content, viscosity, and hedonic test. The test results showed that the value of sucrose content increased along with the addition of sucrose sugar to the syrup, namely 65.61 to 71.46%. The value of this sucrose content has met the SNI for syrup. The highest antioxidant value in the 2 kg sugar treatment was 79.58. In the study of the viscosity, the highest value at treatment with the composition of 2 kg sugar additional. However, the panelists preferred syrup with a sugar composition of 1.5 kg with the highest score marked on the hedonic test.

Abstract
The cantang grouper is one of the high-value fisheries commodities. Transportation is an integral activity in aquaculture, notably in transporting cantang grouper. Among the methods is the closed wet transportation system. The disrupted environment in the closed wet transportation system, exhaustion, and deficit of the immune system can cause the cantang grouper to be infested by marine leech or Zeylanicobdella. In this study, Zeylanicobdella sp. infestation levels and cantang grouper blood glucose levels are compared before and after a closed wet transportation system. This research used an experimental method. The 35 individuals’ sample was examined for blood glucose levels and the infestation degree of Zeylanicobdella. Subsequently, they were transported from Situbondo, East Java, to the Faculty of Fisheries and Marine Universitas Airlangga Surabaya and re-examined. The results of measuring blood glucose levels of cantang grouper were in the below-normal category, normal, and above-normal. There was no significant difference in the infestation degree by Zeylanicobdella sp. between before and after transportation. This study concludes that closed wet transportation affected blood glucose levels and did not affect the degree of infestation by Zeylanicobdella sp. in cantang grouper.

Abstract
This type of sponge Hyrtios erecta has not been widely studied as an antibacterial agent. The method used to extract the Hyrtios erecta sponge is using maceration. The use of this maceration method aims to compare the use of extraction in producing yields. This study used tests such as water content test using the Loss on Drying method, yield test, phytochemical test using the tube method, and antibacterial activity test using the disc diffusion method (Kirby Bauer). The research design used was RAL. Antibacterial activity data using ANOVA. While the data from the other tests were analyzed by descriptive method. The results showed that the use of different extraction methods and extract concentrations resulted in significantly different diameters of the inhibition zones. The results showed that the best treatment in producing the diameter of the inhibition zone was the maceration method with a concentration of 30000 ppm/disk which was 7.08±1.81 for Escherichia coli and 2.83±1.21 for Staphylococcus aureus. Hyrtios erecta extract was more sensitive to gram negative than gram positive. The ethanol extract of the Hyrtios erecta sponge which has been tested in the form of phytochemicals shows the presence of bioactive compounds of alkaloids, flavonoids, and saponins.

Published: December 2023

Abstract
The textile industry is one of the fastest growing industries today. The more the textile industry, the more dye waste is generated. Waste that is not managed properly and is wasted in the waters can cause pollution. Fish that are commonly found in freshwater are the Cichlid group, one of which is tilapia (Oreochromis niloticus) which can be exposed to textile dye waste. Exposure to chemical-based textile dye waste can affect fish physiology, including the formation of fish bones when fish are growing. This can be seen from the results of research on the description of malformation of tilapia exposed to metanil yellow textile dye. This research is an experimental study on juveniles conducted in the laboratory for one month. The results showed that there were malformation in the cephal, truncus and caudal tilapia.

Published: December 2023

Abstract
As an archipelagic country, Indonesia has enormous potential for marine and fishery resources. Basalt areas along the coast of Indonesia are habitats for mangrove ecosystems. However, utilising existing mangrove resources still relies on direct benefits such as mangrove wood which causes damage to the existing mangrove ecosystem. Concepts of sustainable use is to process mangrove fruit into functional food, namely mangrove syrup from pedada (Sonneratia caseolaris). The syrup from the mangrove fruit is combined with the natural dyes of roselle flowers. In this study, storage temperature testing was carried out by observing the value of antioxidant activity and microbiological contamination. Storage was carried out at temperatures of 10, 25 and 35C, respectively, with a storage time of 28 days. The results showed that as long as storage, the value of antioxidant activity decreased. The lowest value at storage is 10; 25; and 35°C respectively 49.73; 43.72; and 39.92. In addition, storage at 35°C for 28 days showed the highest growth of microorganisms, which was 293.33 CFU. This shows that storing mangrove syrup should be carried out at low temperatures (refrigerator) by reducing direct contact with sunlight to maintain the antioxidant quality of the syrup and other nutritional compositions.
