Abstract
This study aims to determine the effect of the application of algae Sargassum sp. extract on the growth of corn plants (Zea mays L.) and the response of soil microbes through the use of the Randomized Group Design (RGD) consisting of 3 repeats. The algae Sargassum sp. extract had 3 concentrations namely algae 30%, algae 60% and algae 90%. Then the algae Sargassum sp. extract was applied to the corn plants (Zea mays. L.) by being poured on the soil. Observation parameters stalk circumference (cm), leaf nitrogen content (%), stalk and leaf biomass (grams), cob weight (grams), husked cob weight (grams), cob length (cm), cob diameter (cm), soil bacteria colonies and soil fungi. The use of algae extracts improved the quality and quantity of corn growth using analysis of variances (F-test/ANOVA) with a confidence level of α = 0,05%. This was followed by analysis with the Duncan test using SPSS Statistics program version 22. The research results showed the application of algae Sargassum sp. extract on corn plants had a significant effect on stalk and leaf vegetative biomass, cob weight, husked cob weight, cob length and cob diameter, but did not have a significant effect on corn plant height, stalk circumference, leaf nitrogen content, soil bacteria colonies and soil fungi colonies. Even though there was not a significant effect, but quantitatively the corn plant growth with alga 30%, alga 60% and alga 90% treatments tended to be better than control.

200 ml of algae extract was applied for each of algae 30%, 60% and 90% and NPK 4.21 grams.The effect of fertilizer on the growth of corn plants was observed by measuring the observation parameters, namely stalk circumference, stalk and leaf biomass, cob weight,husked cob weight, cob length, and cob diameter, as well as observation of microbial response.The research results were analysed using analysis of variances (Ftest) or ANOVA with a confidence level of α = 0,05%
Summary
Corn is a plant which requires a large amount of nutrients to grow and produce a good yield. One cause of low productivity is inappropriate fertilization. The productivity of corn (Zea mays L.) needs to be improved because it is one of the world’s most important food crops [1]. Increasing the production of corn plants requires optimal fertilization because corn is a plant which is responsive to fertilizer. The use of organic fertilizers needs to be optimized as one approach to improve corn productivity. The use of seaweed extract as a fertilizer can help improve soil fertility, improving its capacity to absorb water and providing nutrients as well as improving soil structure [4], protecting plants from
