Soil microbes contained in bamboo roots are classified as Plant Growth Promoting Rhizobacteria (PGPR). PGPR is a soil microbe found in plant roots that can increase plant growth and protect certain pathogens. This aims of this study were to determine the diversity of bacterial isolates from bamboo root baths and the growth and production response of purple eggplant plants (Solanum melongena L.) with the application of biological fertilizers from bamboo root baths. This research was begun with making biological fertilizers from bamboo root baths. Furthermore, the biofertilizer was taken sufficiently to analyze the diversity of bacterial isolates in the laboratory. Each treatment was repeated 10 times, so that the experimental unit was observed as many as 40 plant samples. This study was analyzed descriptively by characterizing isolates and calculating the mean of each parameter. Based on the results of bacterial isolation from bamboo root baths, 8 isolates of bacteria were found with different macroscopic morphological characteristics including 7 Gram-positive bacterial isolates and 1 Gram-negative bacterial isolate and 5 bacillary (stem) isolates and 3 (round) coco isolates. The highest average in all parameters (plant height, number of leaves, leaf width and initial fruit weight) were in the M4 treatment (dose of 20 ml / plant). Keywords: Bacteria, Bamboo Root Baths, Solanum melongena L.

White root fungus disease has become the most damaging root disease in rubber trees in both Africa and Asia that supplies 98% of rubber products to the world market. Chemical control by using pesticide was a common root control of white root fungus. PGPR (Plant Growth Promoting Rhizobacteria) could be one of the solutions in biological control of environmentally to against white root fungi. The aims of yhis study were to obtain isolates of local PGPR bacteria from the root endophytes of oil palm trees, to know the morphological characteristics of local PGPR isolates from root endophytes of oil palm plants, and to know the potential of biological control agents againts white root fungus disease. This research was conducted by using descriptive analysis method. The results showed that there were 9 bacterial isolates from the root endophytes of oil palm plants with different macroscopic morphological characteristic and there were 9 isolatesable to inhibite the growth of white root fungus with the biggest potential was A5 isolate. Keywords : PGPR, Root Endophytes of Palm Oil Plant, Rigidoporus microporus

This study aims to see the differences in the speed of sprout growth with immersion systems and without water immersion. The results showed that there were differences percentage of seeds germinated between seeds that were given water immersion for 12 hours (85%) and were not given water immersion (65%). For the other parameter average days of sprouting, where the seeds that are given water immersion are more quickly induced by sprouts as much as 60% age 7 days after seedling, compared not given water immersion can only be induced by 40%. Likewise, the 17th day after the seedlings were induced by 85% for soaking seeds and 65% for seeds that were not soaking. Keywords: Rubber, Sprout, Water immersion

Today many processed foods using basic materials out. The growing industry out even more rapidly and produce abundant waste. Industrial know in the treatment process generates solid waste and liquid waste. Solid waste is generated from the screening process and clotting, this waste is usually processed into tempe gembus and fodder. The liquid waste is generated out of the washing process, boiling and printing out, therefore the volume of wastewater produced is very high.Waste know will cause a lot of environmental problems. Liquid waste contains high levels of Chemical Oxygen Demand (COD), Biochemical Oxygen Demand (BOD), Total Suspended Solids (TSS), Total Dissolved Solids (TDS) and acidity (pH) is high. However, effluent, rich in organic matter such as proteins, carbohydrates, fats, oils and much more. The study was therefore to utilize liquid waste know as ameliorant land will be required.This research aims to use wastewater know that abundant in society as ameliorant soil to improve plant growth and production. This study uses a randomized complete block design (RBD) with four treatments (0 ml, 100 ml, 250 ml and 400 ml / plant). Plants indicators used in this study is pakcoi mustard (Brassica few).The results showed that the liquid waste out can improve soil chemical properties and a positive influence on the growth and yield of pakcoi. Giving liquid waste out with a dose of 400ml / plant gives the best results in improving soil fertility, growth and crop production pakcoi. Keywords: Liquid waste Tofu Dregs, Growth and Production of Pakcoi (Brassica rapa)

The aim of this research is to know the effect of urea fertilizer and the appropriate Super-Vit fertilizer in order to obtain good peanut plant growth and to see whether there is a real interaction between the two factors on the growth of peanut plant. This research was conducted at Jl. Dewi Sartika Gg. Education. South Rantau District Labuhanbatu Regency of North Sumatra Province, with an altitude of ± 54 M from sea level. The method used is Factorial Random Design (RAK) Factorial with 12 treatment combinations and 3 replications, Urea fertilizer factor Consisting of 4 levels: U0 = 0 gr / plant, U1 = 1 gr / plant, U2 = 2 gr / plant, U3 = 3 gr / plant, while Super-Vit fertilizer factor consists of 3 levels ie: S0 = 0 gr / Plant, S1 = 0.2 gr / plant, S2 = 0.3 gr / plant. Parameters observed were 4, ie plant height, number of pods per sample plant, weight of 1000 seeds, and production amount per plot. The treatment of urea fertilizer had no significant effect on plant height parameter and weight of 1000 seeds, while the effect was very real on the number of pods containing the plant and the amount of production per plot, the treatment of Super-Vit fertilizer showed a significant effect on the parameters of plant height, Pod containing per plant sample, and production amount per plot. But no significant effect on weight parameter of 1000 grain seeds. Treatment of interaction between Urea fertilizer and Super-Vit fertilizer showed no significant effect on plant height parameters, number of pods per sample plant, weight of 1000 seeds, and production amount per plot. Keywords: peanut, compound fertilizer, urea fertilizer.

One of the environmentally friendly control alternatives that can be done, namely by utilizing biological agents in the form of endophytic fungi that are antagonistic. This study aims to study and obtain information about the potential of endophytic fungi in inhibiting white root fungi in vitro. Endophytic fungi isolation is carried out by sterilizing the surface of the stem of the rubber plant and culture it on agar nutrient media. Five endophytic bacterial isolates were obtained from the roots of rubber plants, respectively: JEB01, JEB02, JEB03, JEB04 and JEB05. Fungal isolates were tested antagonistically in vitro against Rigidoporus microporus. Two fungal isolates, JEB01 and JEB02 showed the best antagonist in inhibiting the growth of pathogenic fungi Rigidoporus microporus in vitro. Keywords: endophytic fungi, in vitro, Rigidoporus microporus, rubber plants (Hevea brasilliensis

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
