Abstract

The purpose of this study was to obtain information regarding the potency of the alkaloid active ingredient in jellyfish (Bougainvillia sp) on the immune response of tiger grouper fry infected with Vibrio harveyi bacteria through the immersion method by observing changes in appearance and the amount of plasma protein in tiger grouper infected with bacteria. 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. As a follow-up to the results of this study, it is suggested to carry out further research on the application of immunostimulants using jellyfish alkaloids (Bougainvillia sp.

Abstract

Big chili (Capsicum annuum L.) is one of the vegetables that the request is high enough. 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. From the result of the research it can be conclude that the level of 72 gram/polybag give the best result for the growing of chili plant compared with another treatments.

Abstract

This study aims to determine the response of growth and yield of Sweet corn crops (Zea mays saccharata Sturt) on the provision of liquid waste tofu and chicken manure. This research was arranged by using Randomized Block Design with treatments, namely: Control (P0), liquid waste tofu 300 ml (P1), liquid waste tofu 600 ml (P2), chicken manure (P3), liquid waste tofu 300 ml + chicken manure (P4), liquid waste tofu 600 ml + chicken manure (P5) with 4 replications. The variables observed in this study consist of; plant height, number of leaves, number of cobs, cob weight and wet weight of the plant. Data were analyzed by using variance test (Anova) followed by Duncan 5% test. The results showed that the liquid waste treatment of 600 ml + chicken manure can increase the plant height, the number of leaves, the number of cobs, the weight of the cob and the wet weight of the plant. The best crop yields were found in the treatment of liquid waste of 600 ml + manure (P5) because it was able to increase plant height 61.20%, leaves 40.16%, cobs 79%, cob weight 564,74%, wet weight 163, 83% compared with control treatment (P0).

Abstract

The objective of the experiment was to determine the growth response of oil palm (Elaeis guineensis Jacq) seedlings to the application of planmate organic fertilizer in the main nursery. The experiment used a completely randomized design (CRD) with 5 treatment levels consisting of; P0 = without applying planmate fertilizer, P1 = 300 g per polybag, P2 = 350 g per polybag, P3 = 400 g per polybag, P4 = 450 g per polybag. Each treatment level was repeated 3 (three) times, so that there were experimental units, each plot consisting of 3 (three) polybags of oil palm seeds, so that a total of 45 polybags, all plants were sampled. Parameters observed were soil pH, plant height, seedling stem diameter, plant dry weight, and root dry weight. The results of the study showed that the application of planmate fertilizer had a significant effect on soil pH, plant height, stem diameter, shoot dry weight, and root dry weight. The best dose of planmate fertilizer is 450 g per polybag (P4) to give yields on shoot height, stem diameter, dry weight of plants and dry weight of roots of oil palm seedlings.

Abstract

The aim of the study was to determine the response of growth and production of upland rice (Oryza sativa L.) to the application of vedagro fertilizer and green manure. 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. The best treatment was at a green manure dose of 3 kg/plot (H3).
