Red tilapia (Oreochromis niloticus) is one of the famous fish cultures in the aquaculture industry, especially in Malaysia. The appearance of redness makes the fish more attractive for customers to buy. Product appearance is one of the big criteria that customers choose when they buy food. Bright color effects give high expectations for high quality, nutritious, and healthy food. Therefore, to achieve quality products it is necessary to research how to improve the color quality of tilapia as desired by customers. The purpose of this study was to identify the dietary effect of red paprika used to enhance the coloration of red tilapia. This study is an experimental quantitative study. Red tilapia used as an experimental material was obtained from Freshwater Hatchery, University Malaysia Terengganu. A descriptive analysis was used to analyze the data in this study. This study shows that giving red paprika has an effect on the length and weight of red tilapia, where the highest length and weight gained (1.79 cm and 12.37 g) given red paprika 2% and the lowest length and weight gained (0.63 cm and 2.5 g) which given 4% red paprika. The findings of this study found that only 2% of red paprika treatment showed different growth performance. The crude protein, lipid, and moisture composition of tilapia were also higher at 2% red paprika treatment. Meanwhile, the highest composition of ash is feed with 4% red paprika content. The result of this research showed that the caudal and dorsal either muscle or fin showed the highest color at the fish which fed with 8% red paprika. The finding also found that 8% red paprika containing diet feed for six weeks could improve the coloration of the red tilapia. Future studies suggest the use of Dunaliella salina microalgae which is one of the richest sources of carotenoids used as dyes in food.

Red tilapia, Oreochromis niloticus is the main commodity of freshwater fish in Indonesia. Red tilapia have a good price compared to tilapia. The aims of this experiment to determine of survival, growth, and water quality of red tilapia cultured in aquaponic system. The treatment of this experiment, namely A) Red tilapia cultured without aquaponic (control), B) Red tilapia cultured with pakcoy, and C) Red tilapia cultured with caisin. The result showed that the highest of survival rate, weight, and length absolute found at Red tilapia cultured with pakcoy (96.00±1.73%, 32.31±0.74g, and 7.57±0.21 cm) and Caisin (96.00±1.73%, 32.31±0.74g, and 7.57±0.21 cm) than that of without aquaponic (86.67±1.15%, 25.77±1.05g, and 6.43±0.31 cm) (P<0.05). Vegetable leaf production of pakcoy was 6.57±0.16 Kg and Caisin was 6.17±0.11 Kg. The water quality parameters such as DO, TAN, nitrite, and nitrate of Red tilapia cultured using aquaponics was better than that of without aquaponic.

The Impact

The objective of this study was to evaluate the effect of different feed management on the quality of effluent water generated in Nile tilapia (Oreochromis niloticus) culture ponds. Feed was supplied as follows: natural food, and pelleted, extruded or minced ration. The study was conducted during 19 weeks in 12 continuous water exchange ponds of 300 m² each, with a population of male Nile tilapia juveniles, in a density equal to 1.7 fish m-2. Feeds contained 30% crude protein, 3,000 kcal digestible energy, and were supplied twice a day. Natural food consisted of chicken manure. Temperature, dissolved oxygen, pH, total phosphorus, total nitrogen, chlorophyll a and suspended solids were monitored weekly in the supplying and effluent water. Water residence time was also determined for the ponds. In general, effluent water quality decreased in all treatments.

The most popular fish farmers in Indonesia are tilapia. A decreasing in physical quality of fish after approximately 2 hours of death. The fish can be guaranteed the quality of freshness with preservation. Some people still use preservation by cooling, drying, fumigating, salting and even the formalin substances. This research use natural preservation that use young seed of Picung (Pangium edule Reinw). The aim of research was to determine the effect of the covered pasta duration as a natural preservative against the ratio freshness of red tilapia (Oreochromis niloticus) meat in each treatment. This study used an experimental method consist four treatment; first, without covered pasta at 26 and 18 oC. The second,  the 3 mm of covered pasta of fish at 26 and 18 oC. The assessment of physical appearance performed by organoleptic scoring of fresh fish and Friedman test. The results of this study indicate that red tilapia which is covered with 3mm thickness of Picung young seeds with a refrigerator temperature of 18˚C has score value of the average; eye 6.93, gills 7.68, smell 7.77 and texture 8.5 with at long time fresh of 168 hours.Keywords: organoleptic, covered pasta, long time fresh ABSTRAKBudidaya ikan di Indonesia paling banyak diminati adalah ikan nila. Ikan mengalami penurunan kualitas secara fisik setelah kurang lebih 2 jam setelah kematiannya. Ikan dapat terjamin kualitas kesegarannya usaha yang dilakukan adalah pengawetan. Beberapa masyarakat masih menggunakan pengawetan dengan metode pendinginan, pengeringan, pengasapan, penggaraman dan bahkan formalin. Penelitian ini menggunakan pengawetan secara alami, yaitu pemberian lumuran pasta biji picung mudah (Pangium edule Reinw). Tujuan dari dari penelitian ini adalah untuk mengetahui pengaruh lama waktu pelumuran pasta sebagai pengawet alami terhadap rasio kesegaran daging ikan nila merah (Oreochromis niloticus) pada setiap perlakuan. Penelitian ini menggunakan metode eksperimental, ada empat perlakuan pertama yaitu ikan nila merah tanpa diberi pelumuran pada suhu 26˚C dan 18˚C. Kedua ikan nila merah dilumuri biji picung halus setebal 3 mm pada suhu 26˚C dan 18˚C. Penilaian kenampakan secara fisik dilakukan dengan scoring organoleptik ikan segar dan uji Friedman. Hasil dari penelitian ini menunjukan bahwa ikan nila merah yang dilumuri oleh biji picung muda ketebalan 3mm dengan suhu pendingin 18˚C memiliki skor nilai rata-rata mata 6,93, insang 7,68, bau 7,77 dan tekstur 8,5 dengan lama waktu simpan selama 168 jam.Kata kunci: organoleptik, lumuran pasta, lama waktu segar
