Abstract

Potato Dextrose Agar (PDA) is a popular medium used among white oyster mushroom seedlings. The source of nutrition in this PDA media comes from potato decoction extract, because potatoes have a high carbohydrate content, where in every 100 grams of potatoes contain 85.6 g carbohydrates, 0.3 g protein, and 0.1 g fat. This study aims to determine the effect of concentration and obtain a concentration of potato extract that provides the best growth of F0 seed mycelium. The study was conducted using an experimental method using Complete Randomized Design (RAL) with one factor treatment, namely the difference in potato extract concentration on PDA media, namely with 6 levels of potato extract concentration of 10%, 15%, 20%, 25%, 30% and 35%. The data analysis method using Anova tables is carried out with DNMRT and qualitative descriptive. The results showed that the concentration of potato extract on PDA media had a significant effect on the growth of F0 seed mycelium of white oyster mushrooms (Pleurotus ostreatus) and at a concentration of 25% had provided the best growth.  Keywords: Potato Dextrose Agar, Mycelium Growth, White Oyster Mushroom INTISARIPotato Dextrose Agar (PDA) merupakan media yang populer digunakan dikalangan pembibit jamur tiram putih. Sumber nutrisi pada media PDA ini berasal dari ekstrak rebusan kentang, karena kentang memiliki kandungan karbohidrat yang tinggi, dimana dalam  setiap 100 gram kentang mengandung karbohidrat  85,6 g, protein 0,3 g, dan lemak 0,1 g. Penelitian ini bertujuan untuk mengetahui pengaruh konsentrasi dan mendapatkan konsetrasi ekstrak kentang yang memberikan pertumbuhan miselium bibit F0 terbaik. Penelitian dilakukan dengan  metode eksperimental menggunakan  Rancangan Acak Lengkap (RAL) dengan perlakuan satu faktor yaitu perbedaan konsentrasi ekstrak kentang pada media PDA, yaitu dengan 6 tingkat konsentrasi ekstrak  kentang  10%, 15%, 20%, 25%, 30% dan 35%. Metode analisis data menggunakan tabel Anova dilanjukan dengan DNMRT dan deskriptif kualitatif. Hasil penelitian menunjukkan bahwa konsentrasi ekstrak kentang  pada media PDA berpengaruh nyata terhadap pertumbuhan miselium bibit F0 jamur tiram putih (Pleurotus ostreatus) dan pada konsentrasi 25 % telah memberikan pertumbuhan terbaik. Kata kunci: Potato Dextrose Agar, Pertumbuhan Miselium, Jamur Tiram Putih

Abstract

This study aims to compare technical efficiency (TE), technology gap ratio (TGR) and metafrontier technical efficiency (MTE) of oil palm smallholder oil palm in Sumatra according to their management patterns using data from the 2014 Estate Cultivation Household Survey by BPS-Statistics Indonesia. The result showed that the characteristics of oil palm smallholder production in Sumatra was on the Increasing Return to Scale. The average technical efficiency level of smallholders in Sumatra was 70% for the frontier, 69% for the metafrontier and a technology gap ratio of 99%.   The technical efficiency score for supported smallholders which was higher than the independent smallholders. There is still room to improve the management capabilities of independent smallholders by improving the education level of smallholders.
