Abstract

Ketersediaan Cendawan Mikoriza Arbuskular (CMA) umumnya dalam bentuk propagul yang dianggap kurang efektif sehingga diperlukan teknologi enkapsulasi. Alginat yang sering digunakan sebagai bahan penyalut enkapsulasi memiliki sifat stabilitas viskositas yang mudah turun sehingga diperlukan subtitusi dengan polimer lain. disisi lain, agar-agar mengandung karagenan yang memiliki kemampuan baik sebagai bahan penyalut. penelitian ini bertujuan untuk mengetahui persen infeksi kombinasi konsentrasi bahan penyalut Na-alginat dan agar-agar yang menghasilkan morfologi kapsul yang baik. kapsul dibuat dengan meneteskan suspensi Na-alginat dan agar-agar berbagai konsentrasi ke dalam larutan CaCl.H2O 3%. Parameter pengamatan meliputi morfologi kapsul (warna, bentuk, ukuran, serta tekstur) dan persen infeksi. Data dianalisis menggunakan analisis deskriptif kualitatif. hasil penelitian diketahui bahwa kombinasi konsentrasi bahan penyalut kapsul terbaik dengan variasi 75% alginat : 25% agar-agar menghasilkan morfologi yaitu diameter 5,30 mm, warna keruh, bentuk seragam, tekstur kenyal, serta persen infeksi sebesar 66% yang termasuk kelas infeksi tinggi.

Availability of Arbuscular Mycorrhizal Fungi (AMF) is generally in the form of propagules which are considered less effective so that encapsulation technology is needed. Alginate which is often used as encapsulation coating material has viscosity stability properties that are easy to drop, so subtitution with other polymer is needed. On the other hand, agar contains carragenan which has good ability as a coating material. This study aims to determine the percent infection combination of Na-alginate and agar coating concentrations that produce a good capsule morphology. The capsules were made by dripping a suspension of Na-alginat and agar of various consentrations into a 3% CaCl.H2O solution. observation parameters included capsule morphology (color, shape,size, and texture) and percent infection. data were analyzed using qualitative descriptive analysis. The results showed that the combination of the best capsule coating material concentration with a variation of 75% alginat : 25% agar produced a morphology of 5,30 mm in diameter, cloudy color, uniform shape, chewy texture, and 66% infection percent which belonged to a high infection class.
