Abstract

Local microorganisms (MOL) are microorganism that are used as bio activators in the producing solid and liquid organic fertilizer. The main components of local microorganism are carbohydrates, glucose, and microorganism sources. The research was conducted based on two reasons: (1) the fact that many fruit waste was left unused, for instance, deserted banana sticks, golden snail which considered as a pest to crops, cattle rumen, and (2) the need to reduce dependability on anorganic fertilizer by exploring the role of microorganism. The objective of this research was to produce mol liquid which can be used as bio activator as well as liquid organic fertilizer. The materials used in this production were banana sticks, fruit waste, golden snail, cow rumen, cow urine, coconut water, rice water (lery), shrimp paste, brown sugar for MOL I. MOL II used the same materials except for brown sugar which was substituted with white sugar. MOL was produced through fermentation. The production of MOL was done in the Production Laboratory at State Agricultural Polytechnic of Samarinda. Based on the observation, the combination of MOL was well fermented on day ten. This was shown by dark brown color, stablized temperature, tape smell, and the sight of thin fibre on the mol surface.

Abstract

Durian merupakan tanaman buah di Indonesia, tanaman durian terdapat di seluruh pelosok dengan rasa dan memiliki ciri khas sendiri tiap daerah. Bukan hanya di indonesia tanaman durian tersebar ke seluruh Asia Tenggara, dari Sri Langka, India Selatan hingga New Guenea. Guna meningkatkan hasil produksi durian, maka petani dapat melakukan strategi melalui perbanyakan tanaman durian baik secara generatif maupun vegetatif. Penelitian ini bertujuan untuk untuk mengetahui tingkat keberhasilan dengan menggunakan grafting menggunakan berupa gunting okulasi dan pisau okulasi, serta untuk mengetahui kecepatan waktu pecah tunas grafting tanaman durian dengan menggunakan kedua alat tersebut. Penelitian ini menggunakan 2 faktor perlakuan. Perlakuan pertama adalah alat yang digunakan yaitu G (menggunakan gunting) dan P (menggunakan pisau). Faktor perlakuan kedua adalah jumlah mata tunas (1: menggunakan 2 ruas mata tunas; 2: menggunakan 3 ruas matas tunas; 3: menggunakan 4 ruas matas tunas). Dengan demikian didapatkan 6 perlakuan yaitu G1, G2, G3, P1, P2, dan P3. Masing-masing diulang sebanyak 2 kali ulangan sehingga didapatkan 12 satuan percobaan. Hasil analisis sidik ragam menunjukkan bahwa penggunaa Gunting grafting (G) berpengaruh nyata pada persentase pertumbuhan, berpengaruh sangat nyata pada pecah tunas dan berpengaruh sangat nyata pada jumlah daun 60 HSG (hari setelah grafting). Selain itu, hasil analisis sidik ragam menunjukkan bahwa perlakuan pisau okulasi (P) berpengaruh nyata pada persentase perkecambahan, berpengaruh sangat nyata pada pecah tunas.
