One of the way to increase the production and quality of chili crops is by using a fertilizer that aims in increasing the supplay of nutrients needed by plants, that is by using the rice husk ash of waste factory beside giving the benefit of many biomass it also easy to be gotten. The objectives of this study were to know the influence of the use of rice husk ash for the plant of big chili plant with diffrent quality, and to know which one of the best for the plant to produce big chili with high quality. This research was conducted at MIPA Laboratory of Tarbiyah Faculty, IAIN Raden Fatah Palembang. The research used completely randomized design with 4 treatments and 3 replications, so we got 12 units of the experiment. The treatment were P0=0 gram/polybag, P1=24 gram/polybag, P2=48 gram/polybag, and P3=72 gram/polybag. The result of this research showed that giving 24 gram of rice husk ash got the average plant height 22,67 cm, the total stalks were 13,33, the age when the first flowering day was 50 days, and the total chili were 3,33. The treatment of 48 gram got the average plant height 27,17 cm, the total stalks were 21,33, the age when the first flowering day were 55,67 days and the total chili were 8,67. The treatment of 72 gram got the average plant height 33,33 cm, the total stalks were 35,33, the age when the first flowering day were 44,33 days and the total chili were 22.

Under the guidance of Mrs. Ir. Ernita, MP. This research was carried out in the experimental garden of the Faculty of Agriculture, Riau Islamic University, for four months from February to May 2021. The aim of the study was to determine the response of various doses of vedagro fertilizer and green manure to the growth of upland rice plants. The experimental design used in this study was a completely randomized factorial design consisting of two factors. The first factor was the dose of Vedagro (V) fertilizer which consisted of 4 levels: 0, 30, 60, 90 grams per plot and the second factor was the dose of green fertilizer (H) which consisted of 4 levels: 0, 1, 2, 3 kg per plot. . Parameters observed were plant height, number of productive tillers, flowering age, harvesting age, weight of full grain, weight of empty grain, weight of wet grain in a clump, weight of dry grain in a clump and weight of 100 dry grains. The data were analyzed statistically and continued with the honest significant difference test (BNJ) at the 5% level. The results showed that the application of vedagro and green manure gave a real response to all observed parameters. The best treatment was at the dose of vedagro fertilizer 90 g/plot and green manure 3 kg/plot (V3H3). The main factor of vedagro fertilizer gave a real response to all observation parameters. The best treatment was found at the vedagro fertilizer dose of 90 g/plot (V3). The main factor of green manure gives a real response to all parameter observations.

V. harveyi. The research results obtained explained that the immunostimulant ingredients from jellyfish alkaloids (Bougainvillia sp.) given by immersion can stimulate non-specific and fish-specific immunity. This is characterized by an increase in the amount of protein found in fish blood plasma after administration of alkaloids. Besides that, it can also be seen that the administration of this alkaloid is able to inhibit the infection power of Vibrio harveyi. It is proven that in fish given alkaloid immunostimulants, the amount of protein that appears can be more and the protein content is also high. With a larger protein, it will be able to further stimulate non-specific immunity so that later various antibodies as specific immunity in fish will also be formed. This research ultimately concludes that jellyfish alkaloids (Bougainvillia sp) can be used as immunostimulants to inhibit bacterial attacks Vibrio harveyi in tiger grouper seeds with the optimal dose through immersion method that can be applied is 10.22 ppm.

Data analysis using OLS (Ordinary Least Square) with a double logarithmic function, to obtain the coefficient of elasticity that is in use in static and dynamic analysis model. Elasticity of demand for the static model based on price elasticity, demand for soybeans is inelastic. Based on the income elasticity, soy is a normal good. Whereas for a dynamic analysis model, the elasticity of demand for short-term and long term for soybean prices is inelastic with a value of -0,134 and -0,1595. This means a change of 1% soybean prices will reduce demand for soybeans -0,134% in the short term and -0,1595% in the long term. The elasticity of demand for shortterm and long-term residents for revenue is inelastic with a value of 0,094 and 0,1119.

The low availability of P in Alfisol is due to the bond with Ca to form tricalcium phosphate which is difficult to dissolve. One effort that can be done to overcome the lack of P in Alfisols is the addition of organic matter to the soil, both from plants and animals. The final process of decomposition of organic matter produces humic and fulvic acid compounds which can increase the availability of P. Compost tea is the result of a solution of washing nutrients and extracts of bacteria, fungi, protozoa and nematodes from compost. Compost tea can be given in two ways, namely by spraying it through the leaves and giving it to the soil through the leaves and the soil against the P uptake of corn plants. Compost tea is made using the Bubbler method. Before being applied, the compost must be diluted with distilled water (1:1 ratio) to reduce the concentration. The experimental design used in this study was a completely randomized design with 7 treatments and 3 replications with the following types of treatment: CT0 (control); CT1 (soil + compost tea 130 ml/plant equivalent to 50 l/100 m2); CT2 (soil + compost tea 250 ml/plant equivalent to 100 l/100m2 ); CT3 (soil + compost tea 400 ml/plant equivalent to 150 l/100 m2); CT4 (soil + compost tea 60 ml/plant equivalent to 25 l/100 m2); CT5 (soil + compost tea 130 ml/plant equivalent to 50 l/100 m2); CT6 (soil + compost tea 200 ml/plant equivalent to 75 l/100 m2); The results showed that the application of compost tea through the leaves and soil had a significant effect on the difference in available-P levels. Application of the compost through the leaves increased plant height, number of leaves, plant dry weight and P uptake.

Fusarium wilt occurs in all tomato growing areas around the world and causes huge losses of up to 60%. Control of F. oxysporum pathogens using fungicides on agricultural land can cause environmental pollution. One of the environmentally friendly control alternatives is to use the biological agent Trichoderma polysporum. The results showed that compost containing T. polysporum was effective for controlling Fusarium wilt in tomato plants. The percentage effectiveness of compost containing T. polysporum in controlling the intensity of disease attacks, namely 0% in the control treatment, 47.80% with the application of 0.25 kg of compost containing T. polysporum, and 70.87% with the application of 0.5 kg of compost containing T. polysporum. The effect of time of application of compost containing T. polysporum is equally effective for controlling the pathogen attack of F. oxysporum.
