Abstract

The potential of various genera and species of rhizosphere bacteria is well known. This study aims to determine the diversity and physiological characteristics of the rhizosphere bacterial isolates of oil palm plants at PTPN III Aek Nabara Labuhanbatu North Sumatra. This research was conducted in July 2018 to October 2018 in laboratory of STIPER Labuhanbatu. This research was conducted by isolating bacteria from the root rhizosphere of oil palm plants, characterizing the morphology and physiology of isolates by phosphate dissolution test and indole acetic acid production test. Furthermore, the data was analyzed descriptively. Based on the isolation results obtained 10 bacterial isolates with different macroscopic and microscopic morphological characteristics with the largest amount of dissolved phosphate produced by isolate R05 (0.211 mg / l) and the largest amount of IAA produced by isolate R04 (0.097 mg / l). Isolates R05 and R04 have the potential to be further tested.

Abstract

Efforts to increase the production of chilli plants are still experiencing obstacles. One of the diseases caused by fungi is fusarium wilt disease caused by Fusarium sp. The existence of this fungus attack makes one of the limiting factors that cause a decrease in red chili production. Local microorganism (MOL) solution is a fermented solution made from various local available resources. MOL solution contains micro and macro nutrients and also contains bacteria that have the potential to remodel organic matter, stimulate growth, and as a controlling agent for pests and plant diseases, so that MOL can be used both as a decomposer, biological fertilizer and as an organic pesticide, especially as a fungicide.In this research, bacterial isolation from MOL bamboo shoots will be carried out and then tested the isolates on Fusarium sp. The data of this research were analyzed descriptive. The results of isolation from bamboo shoot MOL which has been fermented for use as POC, obtained 8 bacterial isolates with different macroscopic and microscopic characteristics. All obtained bacterial isolates have the potential to inhibit the growth of fusarium fungal colonies. The most potential bacterial isolate was M6 isolate with a diameter of a pathogenic fungal colony that grew only by 2.1 cm.Keywords: Fusarium sp., Local Microorganisms, Bamboo Shoots

Abstract

The ingredients of MSG derived from nature, especially vegetable materials, cause the MSG solution decompose with other substances. Utilization of Monosodium Glutamate (MSG) as a stimulant of plant growth can be applied to various types of plants. The aim of this study was to know the effect of MSG on the growth of oil palm seed (Elaeis guineensis Jacq.) in pre nursery. This research was conducted with 8 treatments and 3 replications, in which P0: Control, P1: 5 gram / 200 ml, P2: 10 gram / 200 ml, P3: 15 gram / 200 ml, and P4: 20 gram / 200 ml, P5: 25 gram / 200 ml, P6: 30 gram / 200 ml, P7: 35 gram / 200 ml. Observations were done after 4 MST with 2 weekly measurements up to 14 MST. The best rate of the height, the length and the number of leaves of the oil palm plant were at the dosage of P6 (30 grams / 200 ml).
