Abstract

Ikan sidat (Anguilla sp.) merupakan jenis ikan yang mempunyai nilai permintaan ekspor yang tinggi di Indonesia. Tetapi pada tahun 2011 volume ekspor menurun sebesar 39.1% yang diakibatkan oleh lambatnya laju pertumbuhan karena rendahnya daya cerna protein, karbohidrat dan lemak dalam pakan oleh sidat. Pemeriksaan histopatologi merupakan salah satu cara dalam mendiagnosa adanya perubahan sel dalam jaringan ikan. Metode yang digunakan yaitu eksperimental dengan dosis probiotik yang berbeda 10 ml/kg; 15 ml/kg; 20 ml/kg dan 25 ml/kg dan penambahan minyak ikan masing-masing 5%. Dari hasil penelitian, nilai skoring kerusakan histopatologi lambung terendah pada perlakuan dosis 15 ml/kg diperoleh rata-rata dan standart deviasi kerusakan jaringan sebesar (1.40±0.20) radang; (1.27±0.23) kongesti dan (1.53±0.43) nekrosis. Sedangkan nilai makrofag tertinggi pada dosis 15ml/kg dengan nilai 2.13±0.31 sehingga dapat disimpulkan bahwa nilai tersebut mampu memberikan perbedaan yang signifikan terhadap histopatologi lambung pada ikan sidat (Anguilla sp.) selama masa pemeliharaan. Penggunaan probitoik dapat menurunkan resiko kerusakan histopatologi lambung ikan sidat dan dapat lebih efektif meningkatkan daya cerna ikan sidat sehingga dapat diaplikasikan pada budidaya ikan sidat (Anguilla sp.) dengan dosis 15ml/kg dan minyak ikan 5% pada pellet guna meminimalisir kerusakan jaringan pada sel.Kata kunci: Ikan sidat, Kesehatan ikan, Probiotik, Histopatologi

Abstract

The pharmacy is a place for distributing pharmaceutical supplies (medicines) to the public. As an agency that deals directly with customers and the number of suppliers who want to distribute their goods through the pharmacy, it is necessary to choose suppliers to establish good and profitable cooperation. This research was held at the Sulfa Sulfida Lamongan Pharmacy. The purpose of this study is to design and build a decision support system to select suppliers and their implementation. The method used in supplier selection is a weighted product, where suppliers will be assessed based on price criteria, payment tempo, timeliness of delivery, accuracy in number and service support. The results showed that the weighted product method can be implemented in the decision support system for selecting drug suppliers at the Sulfa Sulfida Lamongan Pharmacy. This is evidenced by the same value between the calculation of the system and manually or in the system. Key Word: decision support system, supplier, weighted product
