Disease attack is the biggest obstacle in fish farming activities and is very detrimental to cultivators. Disease control is an important factor to be recognized. The use of herbs is an alternative for disease control that is relatively safe. Moringa oleifera plant is known to contain several secondary metabolite compounds, namely achaloid, flavonoids, tannins and steroids which have antibacterial and antioxidant properties. Several M. oleifera treatment studies are used to treat and prevent fish infected with disease. The purpose of this article is to describe the compounds contained in M. oleifera and their effect for fish health. M. oleifera has a positive effect on fish health, it can be used to treat and prevent disease in fish.

The purpose of this research was to determine the best concentration of citronella oil on the edible coating from chitosan towards the organoleptic quality of pempek. This research used an experimental method consisting of 5 treatments: without edible coating (control one), addition of citronella oil with a concentration of 0%, 1.5%, 2.5%, and 3.5% using 20 panelists as replications. The parameters observed in this research were organoleptic characteristics (appearance, texture, aroma, taste, teeth cutting test, and folding test) based on the panelists' preference level using a hedonic test and chemical analysis (water content and fat content) and shelf life of pempek for each treatment. Chemical test data were analyzed descriptively while the organoleptic test results were analyzed using the Friedman test. Based on the Friedman test, it was found that pempek edible coating chitosan with the addition of citronella oil up to 2.5% is still preferred by panelists with a water content on 1^st day was 53.08% and on 4^th day was 53.05% while the fat content on 1^st day was 1.46% and on 4^th day was 2.72%. Based on the Bayes test, taste is the most important criterion compared to appearance, texture and aroma. Pempek edible coating chitosan with the addition of citronella oil has a shelf life of up to 4 days.

This study aims to analyze supply chain management of lobster in Pangandaran especially PT. ASI Pudjiastuti Marine Product. The research method is a case study with the case unit at PT. ASI Pudjiastuti Marine Product while information would be collected through primary and secondary data in the field. The sampling method in this research used snowball sampling. The research was conducted from August 2020 - September at TPI Pangandaran and PT. ASI Pudjiastuti Marine Product. The criteria used to select respondents in this study as follow; 4 fishermen, 3 distributors, 2 employees of PT. ASI Pudjiastuti Marine Product and 1 retailer. And the data would be analyzed to get the supply chain condition of lobster. The results showed that there were 6 marketing channels in the supply chain of lobster in Pangadaran case study of PT. ASI Pudjiastuti Marine Product. The availability of lobster products has a value of 0.5 which means was not easily replaced and needed. Late payment and distribution of lobster have a value of 1.0 which means irreplaceable and important. The third and fourth chain marketing margins are below 50%, which means efficient for all members of the chain. The fifth chain has 46.55% and it’s inefficient Fisherman's share. The largest market share value was 46.40% on the fifth channel. Supply chain of lobster in Pangandaran has 6 marketing channels which third and fourth are the most efficient for all members, and the second is most profitable for PT ASI.

This study aims to analyze the efficiency and marketing strategy of e-commerce seaweed processed products at Aulia Sari Bandung. The research was conducted with a survey method with a snowball sampling technique to 45 respondents consisting of producers and consumers of the products. The survey results were analyzed descriptively qualitatively. The research was conducted at Aulia Sari Bandung on Jl. Inspeksi Pengairan No. 3 Cipamokolan Bandung City, West Java from July to November 2020. The data sources used are primary and secondary data. Primary data obtained by interviewing informants. Secondary data were obtained from regular consumers or second informants and literature studies related to this research. Data analysis was performed using analysis of SWOT (Strength, Weakness, Opportunity, Threat) and QSPM (Quantitative Strategic Planning Matrix). The results showed that the coordinates of Aulia Sari Bandung are at position X, Y = 0.37; 0.10, which means that it is in quadrant I position by supporting aggressive strategies which means having opportunities and strengths than can be utilized maximally. Some alternative strategies that can be done are maintaining the quality of production, improving and facilitating services using Whatsapp and Go-Food, increasing promotion and sales via Instagram and Facebook, maintaining marketing from Whatsapp and Go-Food to obtain maximum benefits, and improving product promotion and marketing through online marketing media to make it look attractive.

The nutritive value of smoked, dried Procambarus clarkii sourced from Akwa Ibom, Rivers and Lagos states of Nigeria were evaluated and compared.  The proximate composition of the crayfish samples were determined using official methods of analysis, mineral composition were determined using Atomic Absorption Spectrophotometer and  the amino acid composition were analysed using Amino Acid Analyser. The proximate composition of the crayfish samples from three different locations (Akwa Ibom, Lagos and Rivers states) such as moisture, crude protein, crude fat and ash contents showed significant difference (p<0.05) across the selected locations while crude fibre and carbohydrate content showed no significant difference (p<0.05) across the selected locations. The amino acids composition gave the crayfish sample from Akwa Ibom state as the richest source of essential amino acids. The mineral contents of the crayfish samples such as potassium, phosphorus, magnesium, manganese and calcium showed significant difference (p<0.05) across the selected locations while calcium, zinc and sodium contents showed no significant difference (p<0.05) across the selected locations. Comparing their nutrient component, smoked, dried P. Clarkia from Awka Ibom state possess the richest nutritive value.
