Authors: Zamzami L , Azwar A , Ermayanti E 
Published: December 2021

AbstractThis study aimed to determine the patterns of development and implementation of community-based ecotourism management and identify the impact of the community-based ecotourism in Gasan Gadang Village on the economic, social, and environmental aspects of the surrounding community. The methodology used was descriptive analysis with a new institutional economics approach and the Kruskal-Wallis Test analysis. The patterns of development and implementation of community-based ecotourism management with all levels of social change analysis, including formal and informal rules such as culture, customs, habits of Gasan Gadang villagers, institutional and governance management, and even the economy, are considered good. The Community-based ecotourism management has adopted the theory of resource allocation among stakeholders of Gasan Gadang Village. The findings of this study showed that community-based ecotourism institutions and management bring positive impacts on economic, social, and culture. There was no significant difference among economic, social, and environmental impacts between the non-authorities and community-based ecotourism authorities of Gasan Gadang Village. Thus, it could be said that the benefits of community-based ecotourism received by the community were all the same. Everyone got positive benefits. However, based on the findings, it could be seen that the biggest difference was the economic impacts followed by the social impacts, while the smallest difference is the environmental impacts. From this situation, it could be concluded that the performance of community-based ecotourism authorities in Gasan Gadang Village was good and positively impacted the economic, social, and environmental aspects of the Gasan Gadang Village fishermen community.

Abstract
A strategic step on food security was directed by president to the Ministry of Defence. Coastal communities are key actors in the realization of the blue economy and are the determinants of the successful implementation of Indonesia’s policy to becoming the Global Maritime Fulcrum. There are ten provinces on Sumatera which have marine coastal areas with abundant fishery potential. However, that potential has not been fully utilized. This article aims to review opportunities and strategies in realizing the blue economy by empowering coastal communities in the Sumatra. The method was a qualitative exploratory method with SWOT and combined with SSM analysis. The data sources were obtained through secondary data from literature studies, comparisons through multi institutions data. The study found that community empowerment can be done by considering the potential of fishery resources and the community’s interest in managing the fisheries sub-sector. The development of national food barns should be focused on the Blue Economy sector and can be started through the Sumatra region. Stakeholder synergy can be integrated in fostering, supervising and mobilizing coastal communities in supporting their welfare.

Published: December 2021

Abstract
Embryos of the genus Oryzias have long been used as sentinel organisms in ecotoxicological research. Compared with animal models from mammals, Oryzias embryo offers several advantages such as being cost-effective, more sensitive, rapid and produce very little waste. In ecotoxicological studies, it is necessary to have inter-laboratory calibration on used techniques between one laboratory and another, so that the used techniques are reliable. Inter-laboratory calibration between laboratories requires transferring embryos from one laboratory to another. For this purpose, research has been carried out to compare the survival of embryos reared in water and non-water (dry) media until they hatch. The results showed that the embryos reared with dry media hatched one day faster than those raised in water media. The dry-incubated embryo also had an average total length longer than those incubated with embryo rearing media (ERM). In this study, it was concluded that fish embryos of Oryzias celebensis could be transported dry for up to five days.

Bivalves is the second most diverse group of molluscs after gastropods, they are also one of the most important members in marine ecosystems. Their taxonomic classifications are based on their morphology which tend to represent adaptation responses to ecology. The samples of bivalves examined in this study were taken in the South Bintan waters by Marine Geological Research and Development Center, Bandung. Identification of the bivalves shell samples was with the aid of a microscope and NIS-Elements software and identified using an identification book. There were 34 species of bivalves found in South Bintan Waters belong to 14 families. The highest abundance was in Station 1 the location close to the overflow of the river and a harbor (1162.5 ind.m-2) and the lowest was in Station 10 the location Station 10 the location close to a small island which is usually used as a tourist spot (62.5 ind.m-2). Their diversity and eveness index were included in the medium category with H’ value of 0.58-4.12 and e value of 0.11-0.89 respectively. There was species dominance in Station 3 (Liralucina lyngei of Lucinidae) and 10 (Cardites bicolor of Carditidae) but not in other stations. Both species was the most frequent species. Bivalves in South Bintan waters showed many different morphologies which represented their adaptation. The bivalve shells found were of different morphology. There are several forms of bivalve shell morphology that have shape round like species Chama japonica, triangular like species Gemma gemma, fragile like species Dendostrea rosacea. The shell decorations found in the bintan Bivalves samples are Spinose, Commarginally, Commarginally and radially ribbed. The hinge teeth are heteroodont, isodont, and schizodont.

Abstract
Dugongs are generally shy animals, so observing their existence is very limited to hundreds of meters. In contrast to the behavior of Dugong who lives in the coastal waters of Mali, Kabola Regency, Indonesia. Its uniqueness can interact with humans at a very close distance and can even be on the back. It is, therefore, necessary to explore other behavioral patterns and habits and biophysical habitats of Dugongs as information to maintain their survival. This research aims to find out the behavior and biophysics of dugong habitat in the coastal waters of Mali, Kabola Subdistrict, Indonesia. The study uses direct observation methods in the form of observing the characteristics and biophysical conditions of dugong habitats including (1) determining dugong activity areas using GPS coordinates; (2) observe habitat characteristics and biophysical conditions by observing biotic and abiotic conditions, and (3) measuring physicochemical parameters, namely temperature, salinity, and pH. Next, to observe the daily behavior of dugongs when interacting with their habitat environment in the form of time: breathing, going around the boat, swimming at the bottom, swimming on the surface, swimming in the water column, resting at the bottom, eating and exposing the back. In the observations, dugongs swimming around the ship immediately responded and then approached and rubbed his body to the leg then through the pectoral fins that tried to hug to get a leg on the model being tested. Then turn under the boat and remove the penis. In general, the biophysical conditions of sandy and dense habitats are overgrown with seagrass.

Published: December 2021

Abstract
Cymothoid isopod research is relatively scarce in the Philippines, despite the local economic significance of bigeye scad as an inexpensive source of protein and other nutrients. Isopod parasitism has also been shown to have detrimental effects on their fish hosts. The current study aimed to define the host-parasite relationship between cymothoid isopod and bigeye scad by determining cymothoid isopod prevalence, intensity, and host-parasite length correlations in bigeye scad (Selar crumenophthalmus) hosts sourced from Batangas, Philippines. Fish samples were sampled from the Tagaytay City Market in Cavite, which sources fish directly from Batangas. Fish samples were immediately measured and inspected for isopods in the branchial and buccal cavities. Isopods found were extracted, measured, and preserved in ethanol for identification. The isopods were identified as cymothoid isopods and consisted mostly of Norileca indica specimens and one Glossobius impressus. Prevalence and mean intensity of cymothoid isopod infections in bigeye scad were 30% and 1.6, respectively. A possible correlation between isopod size and host size was speculated for non-ovigerous female isopods, but data for male and ovigerous female isopod specimens were inconclusive. The host-parasite size relationships between bigeye scad and isopods are less likely based on body size of either the host or the parasite and are more likely based on other factors such as host cavity size.

Abstract
Micro, Small, and Medium Enterprises (MSMEs) in Indonesia have grown quite rapidly and play an important role in modern economies. Many innovative products have been developed; however, the monitoring of product quality is rare. The aim of this study was to perform a comparative evaluation of the characteristics of agar sheet products from local MSMEs in Java Island, Indonesia. Moisture content, acid-insoluble ash content, total mould count, heavy metals (Pb, Zn, and As, Cu, Sn, Hg) and gel strength of three different agar sheet products were evaluated. Moreover, evaluation of its commercial packaging was carried out according to the regulation of the National Agency of Drug and Food Control (NADFC). The results reveal that the moisture content of agar sheets ranged from 17.48 % to 21.64 %, the acid-insoluble ash contents were lower than the maximum limit by Indonesian National Standard (INS), whereas according to the sensory inspection, the presence of mould was not found. Heavy metals were found at low levels, below the maximum allowable limit by INS. However, all agar sheets have poor gel strength (approximately 32.24 g/cm2 – 77.49 g/cm2). The result of packaging evaluation showed that neither packaging design, nor packaging label of all agar sheet products were excellent. The packaging label was prepared inappropriately according to NADFC. In conclusion, these agar characteristics and packaging quality were lack the minimum standard required. Therefore, product enhancements, such as processing and packaging innovations can be introduced to meet the minimum standard and improve the quality.

Abstract
The edible film is a thin sheet that functions as a coating or packaging material on foods that may be eaten simultaneously as packaged products. The ingredient that is often used is alginate made from seaweed. The advantage of using seaweed as a bioplastic material is that it can be produced in a large quantity, low price, and is non-toxic; it can also produce bioplastic that resembles conventional plastic. The experimental method with two components of Completely Randomized Factorial Design was employed in this study (CRFD), the concentration of Gracilaria seaweed powder with four levels (0%, 0.5%, 1%, 1.5%, and 1%) and concentration of alginate with three levels (1%, 1.25%, dan 1.5%). The result showed that the concentration of seaweed powder and concentration of alginate that used in the making of the edible film had a significant effect on the quality of the edible film on all parameters, which is thickness, moisture content, tensile strength, elongation, water vapor transmission rate, water-solubility, color, opacity and surface morphology. There is an interaction between the concentration of seaweed powder and concentration of alginate at the significant effect on the quality of the edible film, which is a concentration of seaweed powder at the level of 1.5% and concentration of alginate at the level of 1.5%. The film has a the thickness of 0.25mm, moisture content of 6.94%, tensile strength of 54.29 Mpa, elongation of 3.26%, the water solubility of 64.41%, water vapor transmission rate of 3242 g/cm2/24 h, and opacity of 81.7%.

Authors: Ilza M , Karnila R 
Published: December 2021

Abstract
Biscuits are additional food for toddlers. Biscuits on the market are biscuits that contain trans fatty acids which are less safe for toddlers to consume. Because it is necessary to create biscuits that are safe for toddlers to consume by adding fish oil in their manufacture, then biscuits can be given to children who are malnourished. Applications for biscuits are 50 grams/day for children whose body weight is less than WHO standards, 40 grams/day for children whose body weight is less than WHO standards, and 30 grams/day for children whose body weight is according to WHO standards. Every week (for 8 weeks) a toddler’s body weight is measured, as well as observing motor, cognitive, language and social emotional development. Based on the initial weight of the child without the addition of biscuits, it is known 33.3% have a normal weight gain and 66.3% have a late weight gain. After biscuit administration, it was found that weight gain was in a better direction, with 87.4% having a normal weight according to their age and the remaining 13.6% still having late weight development, children whose initial weight was very less than WHO standards. Weight gain is greatly influenced by the number of biscuits given to toddlers. So anatomically, growth will occur in a child’s body structure that increases proportionately with age. A lack of initial body weight will hinder the rate of weight gain of the child, can directly inhibit the growth of the child, as a result the proportion of the body structure of the child is not following their age which in the end it will have implications for other developments. Growth that occurs will affect the development of gross motor and fine motor skills, cognitive, language, and social-emotional toddlers.
