Abstract

Either decorative fish or consumption fish would be costlier in price if sold in a state of life. However both having the same problems that is death at the time of transportation process. From former research has been obtained information that transportation of fish in a state of life can be done by using material anaesthesia either experiencing and also artificial. Usage of chemical material as fish anaesthetic is felt able to give unfavourable effect to quality and fish health. Purpose of this research knows concentration of metel thorn apple leaf extract and soaking stripper that is most effective in anaesthesia of fish koi (Cyprinus carpio L.) and knows does metel thorn apple leaf extract can lessen fish mortality koi (Cyprinus carpio L.) at the time of transportation of long distance. Initial concentration which will be applied is 0,4%, 0,1%, 0,06%, 0,03% and 0% as control, because concentration doesn't have an effect on concentration is boosted up to become 0,4%, 0,7% and 1% with soaking stripper 4, 8, 12 hours. Result of research shows concentration of 0,7% and soaking stripper of 8 hour, this time is most effective in anaesthesia of fish koi (Cyprinus carpio L.) because level of survival rate 100% with induction time stripper and recovery time is stripper. Research is continued with test trasportasi compared to control, where fish is not anaesthetized packed into plastic poke and given with pure oxygen like treatment that is usualy is done the fish farmers in process of transportation. Result of this research indicates that, treatment of fish anaesthetized with metel thorn apple leaf extract level of pass of life reachs 91,667% while controlling 66,667%. From result of inferential research that usage of metel thorn apple leaf extract at the time of transportation of proven long distance can lessen fish mortality koi (Cyprinus carpio L.).

Abstract

The waste of shrimps in the form of skin, head, and tail that is disposed from shrimp processing and disposal are usually thrown away with out being processed, therefore the wastes may cause environmental pollution, especially from the unpleasant stench. Shrimp wastes contain compounds called chitin and can be utilized to absorb heavy metals which are mainly from industrial wastes. The batik industries in Solo usually utilize synthetic colors, because synthetic colors are cheaper and can make the products look more satisfying. Nevertheless, the liquid wastes from these batik industries are usually still colorful when it is disposed and are usually hard to be degraded by nature. Moreover, these wates contains heavy metals such as lead (Pb) and copper (Cu) that can endanger the human health. This research is conducted in order to notify the performance of chitin in order to absorb heavy metals such as lead (Pb) and copper (Cu). There are five treatments that is conducted in this research by adding chitin powder as much as 0 g (control), 1, 2, 3 and 4 g into the sample of batik liquid wastes. The lead (Pb) and copper (Cu) substance of the sample will then be measured using the AAS (Atomic Absorption Spectrophotometer), then the lead (Pb) and copper (Cu) substance of each treatment will be compared with the control. The result of the research shows that chitin can reduce the content of lead and copper in batik liquid wastes. Based on the research result, it is concluded that the addition of 4 g of chitin powder into the sample of batik liquid wastes can give the most maximum result, i.e. the reduction of the Pb content by 6.138 ppm from the control of 17.773 ppm into 11,635 ppm, and the reduction of the Cu content by 3.779 ppm from the control of 7.903 ppm into 4.104 ppm.

Abstract

The objective of this research was to prove that galangale rhizome (Alpinia galanga L. Swartz) can be used to preserved “pindang” tuna fish (Euthynnus pelamis L.). The fish were cooked by galangale rhizome solution (the concentration were 0, 50, 100, 150, 200 mg/l b/v) for15 minutes. Then, the fish were stored in box, three fishes /box, and stored at room temperature for 6 days. Every day, The quality of fish were measured as colour, rubberness, taste, odor, total of bacteria and fungi. The result showed that there were decreased of the fish quality, spoilaged, and many fungi and bacteri growth after two days, and the level of spoilage of fish was influenced the increasing of galangale rhizome concentration. It concluded that the galangale rhizome can not use as “pindang” tuna fish preservative.

Abstract

Shrimp’s skin and carapace has been used as color enhancement. The shrimp’s skinand carapace was pounded into flour and added to the commercial pellet availablelocally. The shrimp’s flours contains red pigmen astaxanthine. The Koi’s used in thisexperiment were two months old Cyprinus carpio L var kohaku. Five level of differentconcentration of shrimp’s flour were used i.e. 5.7%, 8.5%, 11.4%, 14.2%, and 17.1%respectively. Each aquarium contains three fishes were used in threeplicate and rearedfor 8 weeks. Five main color or hue was observed i.e. Redish Orange, Pastel Orange,Orange Red or Yellowish Red, Red and High Red or Vivid Red. 15 panelis have beenused to give their comments to the color enhancement. The results shows that the valueof the fish’s color didn’t change much, but the chrome intensity increase on week eight.Statistical analysis of Kruskall-Wallis and Mann-Whitney Test shows that on theconcentration of shrimp flour of 11,4% was giving the best value for hue and chrome.On the consentration of 14,2% and 17,1% the results were not strong enough. This isprobably because the concentration of the flour reaches maximum at 11,4% and givingmaksimum color enhancement level so that more additioing didn’t gave any change.
