Abstract

ABSTRAK
(Endah Setyo Rini. 26020119120022. Pengaruh Enzim Fitase dalam Pakan Buatan terhadap Peningkatan Efisiensi Pemanfaatan Pakan dan Pertumbuhan pada Ikan Patin (Pangasius sp.) Stadia Pembesaran. Diana Rachmawati & Sarjito).
Pemberian pakan buatan dalam budidaya ikan patin (Pangasius sp.) merupakan salah satu faktor penting dalam meningkatkan produksi. Penggunaan sumber nabati lokal mengandung zat anti-nutrisi berupa asam fitat. Asam fitat akan mengikat mineral-mineral seperti besi, magnesium, kalsium dan seng untuk membentuk kompleks yang sulit diserap usus. Oleh karena itu diperlukan penambahan enzim fitase dalam pakan buatan. Enzim fitase akan menghidrolisis zat anti nutrisi menjadi inositol dan asam fosfat, sehingga penyerapan nutrisi, efisiensi pemanfaatan pakan dan pertumbuhan menjadi maksimal. Penelitian ini bertujuan untuk mengetahui pengaruh penambahan enzim fitase dalam pakan buatan terhadap rasio konversi pakan, efisiensi pemanfaatan pakan, rasio efisiensi protein, laju pertumbuhan relatif dan kelulushidupan ikan patin. Ikan uji yang digunakan pada penelitian ini adalah ikan patin dengan bobot rata-rata 11,55  0,21g/ekor dan padat tebar 40 ekor/m3. Metode yang digunakan adalah metode eksperimental dengan Rancangan Acak Lengkap, 4 perlakuan dan 3 kali ulangan. Perlakuan dalam penelitian ini adalah penambahan enzim fitase dalam pakan buatan dengan dosis berbeda yaitu A (0 FTU/kg pakan), B (500 FTU/kg pakan), C (1.000 FTU/kg pakan), dan D (1.500 FTU/kg pakan). Data yang diamati meliputi laju pertumbuhan relatif (RGR), efisiensi pemanfaatan pakan (EPP), rasio efisiensi protein (PER), rasio konversi pakan (FCR), kelulushidupan (SR) dan kualitas air. Hasil penelitian menunjukkan bahwa penambahan enzim fitase dalam pakan buatan memberikan pengaruh nyata (P<0,05) terhadap RGR, EPP, PER, dan FCR namun tidak berpengaruh nyata terhadap SR. Dosis optimum enzim fitase berkisar 738810 FTU/kg pakan mampu menghasilkan EPP sebesar 69,30% dan RGR sebesar 4,77%/hari untuk ikan patin stadia pembesaran. Kualitas air pada media pemeliharaan berada pada kisaran yang sesuai untuk budidaya ikan patin.

ABSTRACT
(Endah Setyo Rini. 26020119120022. Effect of Phytase Enzyme in Artificial Feed on Feed Utilization Efficiency and Growth of Pangasius Catfish (Pangasius sp.) during the Grow-out Stage. Diana Rachmawati & Sarjito).
Artificial feeding in Pangasius catfish farming (Pangasius sp.) is one of the important factors in increasing production. The use of local vegetable sources contains anti-nutritional substances in the form of phytic acid. Phytic acid will bind to minerals such as iron, magnesium, calcium and zinc to form complexes that are difficult for the intestines to absorb. Therefore, the addition of phytase enzymes in artificial feed is required. The phytase enzyme will hydrolyze anti-nutritional substances into inositol and phosphoric acid, so that nutrient absorption, feed utilization efficiency and growth are maximized. This study aims to determine the effect of adding phytase enzymes in artificial feed on feed conversion ratio, feed utilization efficiency, protein efficiency ratio, relatif growth rate and survival rate. The test fishused in this study were catfish with an average weight of 11,55  0.21g /fish and a stocking density of 40 fish /m3. The research used exsperimental method with a completely random design, 4 treatments and 3 repeats. The treatment in this study was the addition of phytase enzymes in artificial feed with different doses, those were A (0 FTU /kg feed), B (500 FTU /kg feed), C (1,000 FTU /kg feed), and D (1,500 FTU /kg feed). The data observed include relative growth rate (RGR), feed utilization efficiency (EPP), protein efficiency ratio (PER), feed conversion ratio (FCR), survival rate (SR) and water quality. The results showed that the addition of phytase enzymes in artificial feed had a noticeable effect (P<0.05) on RGR, EPP, PER, and FCR but had no real effect on SR. The optimum dose of phytase enzyme ranges from 738-810 FTU/kg of feed capable of producing
EPP of 69,30% and RGR of 4,77%/day for Pangasius catfish grow-out stage. Water quality in the maintenance medium is at a range suitable for Pangasius catfish farming.
