Abstract Mackerel (Rastrelliger sp.) is a kind of fish that have high economic value and good nutrition but susceptible to decay. People often to use formaldehyde as a preservative so that the fish does not quickly to decay. The use of formaldehyde could be replaced by natural ingredients that contain antibacterial compounds, one of which is Kappaphycus alvarezii. This study aims to determine the effect of red algae extract (K.alvarezii) against the total number of bacteria and organoleptic value of mackerel (Rastrelliger sp.). The research design that done in this study is Completely Randomized Design (CRD). The treatments that given are immersion of mackerel in a solution of extract of K. alvarezii with a concentration of 0 ppm, 600 ppm, 700 ppm, 800 ppm and 1% solution of formaldehyde with four repetitions in each treatment. Data analyzes using Analysis of Variants (ANOVA) and followed by Duncan's Multiple Range Test to determine differences between treatments. The results showed that the extract of red algae (K.alvarezii) at a concentration of 0 ppm, 600 ppm, 700 ppm and 800 ppm significantly (p <0.05) against the total number of bacteria of mackerel (Rastrelliger sp.). The ability of extract of K. alvarezii at a concentration of 800 ppm equivalent to the ability of formaldehyde as an antibacterial ingredient in mackerel. K.alvarezii extract could inhibit the growth of bacteria but have not been able to maintain the quality of mackerel based on organoleptic test.

Maggot black soldier fly (Hermetia illucens) is a protein source of feed which is highly favored by poultry, especially ducks and chickens. However, it is feared that the provision of live maggot in ducks will affect the organoleptic quality of the egg, especially its taste and aroma. Therefore this study aims to determine the organoleptic quality of duck eggs fed Hermetia illucens maggot feeds in a living state. The study used 120 alabio ducks which were placed in a postal cage. The design used was a completely randomized design, each treatment using six replications. Each replication is taken egg sample to be tested panelists. The panelists used were 67 panelists who were somewhat trained. The data obtained were analyzed of variance and Duncan's multiple range test. The treatments that were tried consisted of P1: low protein rations without live maggot, P2: low protein rations with live maggot administration 40 g/bird/day, P3: high protein rations without live maggot administration, and P4: high protein rations with live maggot administration 40g/bird/day. The results showed that the treatment affected the texture, flavor, and aroma of boiled eggs. Ducks fed with high protein ration coupled with the provision of live maggot 40 g/bird/day produce softer textures, tastes quite good, and aroma more fishy. Keywords: Maggot, duck eggs, organoleptics
