Abstract

AbstrakIkan Patin (Pangasius pangasius) merupakan ikan air tawar yang memiliki nilai ekonomis yang tinggi. Untuk membantu mempercepat pertumbuhan selain dengan menggunakan pellet, ikan patin juga dapat diberikan pakan alami seperti keong mas (Pomacea canaliculata Lamarck), bekicot (Achatina fulica) dan siput air tawar (Lemnaea javanica). Penelitian ini bertujuan untuk mengetahui pengaruh pemberian pakan jenis keong-keongan yang berbeda terhadap pertumbuhan, kelangsungan hidup, dan konversi pakan. Hasil penelitian menunjukkan bahwa pertumbuhan terbaik terdapat pada perlakuan A, yaitu dengan pemberian keong mas. terbaik kedua pada perlakuan B (pemberian bekicot) dan yang paling rendah pada perlakuan C (pemberian keong air tawar). Selanjutnya untuk tingkat kelangsungan hidup terbaik terdapat pada perlakuan A dan B yaitu sebesar 95.24%, dan yang terendah perlakuan C sebesar 90.47%. Rasio konversi pakan pada perlakuan A yaitu 3.45, sedangkan pada perlakuan C sebesar 7.44.Kata kunci: ikan patin; keong mas; bekicot, siput air tawar; pertumbuhanAbstractPangasius catfish (Pangasius pangasius) is a freshwater fish that has high economic value. To accelerate growth in addition by using pellet, this catfish can also be given live food such as the golden snail (Pomacea canaliculata Lamarck), edible snail (Achatina fulica), and freshwater snail (Lemnaea javanica). This study aims to determine the effect of different types of snail feeding on growth, survival rate, and feed conversion ratio. The results showed that the best growth was found in treatment A, by giving the golden snail, the second best growth in treatment B (by giving edible snail) and the lowest growth in treatment C (by giving freshwater snail). Furthermore, the best survival rate is in treatment A and B which is equal to 95.24%, and the lowest in treatment C (90.47%). Feed conversion ratio in treatment A was 3.45, while in treatment C was 7.44.Keywords: Pangasius catfish; The golden snail; edible snail; freshwater snail; growth

Abstract

This study aims to reduce production costs for feed by adding the pineapple waste extract to commercial feed which increases feed utilization efficiency, relative growth rate, protein efficiency ratio, Survival rate, water quality, and Organoleptic Test. This research was conducted from March 31 to April 28, 2022. At the Hatchery and Technology Laboratory Faculty of Agriculture Department of Aquaculture. This study used a non-factorial Completely Randomized Design (CRD) consisting of four treatments and three replications. Treatment A (0% pineapple waste extract + 100 gr feed) B (3% pineapple waste extract + 100 gr feed) C (4% pineapple waste extract + 100 gr feed) D (5% pineapple waste extract + 100 gr feed). The best results from treatment C with feed utilization efficiency of 80.45%, relative growth rate of 4.79%/day and protein efficiency ratio of 1.73%/day. Survival 81,66% and Water Quality. Temperature 26 - 28 oC, DO 7,0 - 7,5 mg/L, pH 7,1 - 7,3, Salinity 32 ppt, Ammonia 0,04-0,08 mg/L. and Organoleptic Test of Color and Scent, the best feed has a very brown color and does not have an overpowering Scent.Keywords: Growth; Pineapple; Survival rate; Vaname Shrimp.

Abstract

Microalgae are single-celled microorganisms with pigments and can produce photosynthesis to produce food and oxygen. The addition of liquid organic fertilizer from wild banana stem waste (Musa acuminata) and coconut husk as a source of nutrients can be used to increase the cell density of Spirulina platensis. This research was conducted on September 18-27 at the Hatchery and Aquaculture Technology Laboratory, Aquaculture Study Program, Department of Fisheries and Marine, Faculty of Agriculture, Malikussaleh University. The method used in this study is an experimental method with a non-factorial Complete Randomized Design (RAL) of 5 treatments and 3 repeats. The study is treatment A Control (Walne fertilizer), treatment B (Mixture of POC Waste of forest banana stems and coconut husk 12 ml / L of sea water), treatment C (Mixture of POC Waste of forest banana stems and coconut husk 14 ml / L of seawater), treatment D (Mixture of POC Waste of forest banana stems and coconut husk 16 ml / L of seawater), treatment E (Mixture of POC Forest banana stem waste and coconut husk 18 ml/L seawater). The results of this study showed that the use of POC from forest banana stem waste and coconut husk as a culture medium for Spirulina platensis had a real effect with F calculate 43,850 > F tabel (0.05) 3.48 to the peak population and had a real effect on the growth rate of Spirulina platensis with F calculate (26,884) > F table (0.05) 3.48.Keywords: Coconut husk; POC; Spirulina platensis; Wild banana stem waste.
