Abstract

Daun pepaya merupakan bahan alami yang sering dimanfaatkan dibidang perikanan air tawar khususnya sebagai pakan tambahan, karena memiliki kandungan enzim yang dibutuhkan oleh ikan. Penelitian ini bertujuan untuk menganalisis pengaruh penambahan serbuk daun pepaya pada pakan untuk meningkatkan pertumbuhan ikan lele (Clarias sp). Pakan yang digunakan pada penelitian ini yaitu pakan komersil dengan kandungan protein 30% yang ditambahkan serbuk daun pepaya. Serbuk daun pepaya didapatkan dari daun pepaya yang dikeringkan terlebih dahulu sampai benar-benar kering. Setelah kering daun pepaya dihaluskan dengan menggunakan blender. Penelitian dilakukan secara eksperimental menggunakan Rancangan Acak Lengkap (RAL), dengan 4 perlakuan dan 3 ulangan. Perlakuan 1 (P1) sebagai kontrol (tanpa pemberian serbuk daun pepaya), P2 (pakan dengan serbuk daun pepaya 2 %), P3 (Pakan dengan serbuk daun pepaya 3,5 %), P4 (pakan dengan serbuk daun pepaya 4,2 %). Parameter pertumbuhan merupakan parameter utama yang diamati pada penelitian ini. Analisis data menggunakan ANOVA untuk meliihat perbedaan pengaruh dari masing masing perlakuan dengan selang kepercayaan 95% (p>0.05). Hasil penelitian menunjukan bahwa penambahan serbuk daun pepaya memberikan pengaruh nyata terhadap laju pertumbuhan panjang dan berat (p>0.05), dimana perlakuan terbaik terdapat pada P3 dengan pertumbuahan panjang sebesar 2,69 g dan 3,51 cm, berat dan panjang spesifik 3,89 g dan 5,89 cm, serta FCR 0,517.   Kata kunci: pertumbuhan, serbuk, daun papaya

Abstract

Tilapia (Oreochromis niloticus) is a species of freshwater fish that is widely cultivated in areas that have a large quantity of fresh water. In the cultivation of tilapia fish are often infected by fish diseases which not infrequently thwart the growth and survival of fish resulting in death of fish that are cultivated (crop failure). This study aims to analyze the response of giving neem leaf extract (Azadiracta indicida) to the immune system and growth of tilapia. The fish were given neem leaf extract which was added to the feed for 45 days in 54cm x 37cm x 29cm containers each with 10 heads / container with a volume of 20 liters. The study was conducted in 5 treatments, control + (commercial feed and infected by Aeromonas hydrophila 106 cfu / ml as much as 0.1 ml / head), control - (commercial feed of bacterial infection), P1 (feed mixed with 0.5% extra neem leaves and infected with bacteria ), P2 (1% extracted and infected), P3 (2% extracted and infected). The results showed that administration of neem leaf extract at a dose of 1% was able to maintain SR by 100%, increasing the number of erythrocyte tilapia by 15.0 í­” 105 cells / ml and leukocytes by 15.0 í­” 104 cells / ml and hemoglobin by 6.0 % of the total blood cells contained in P4 that play a role in the immune system of tilapia. Based on the results of this study, neem leaf extract can be used in tilapia aquaculture as an immunostimulant because it can improve survival, red blood cells, white blood cells and hemoglobin.Keyword : Extract neem leaves, Aeromonas hydrophila, Tilapia, Feed.
