This study aims to determine the population and genetic parameters of population F3 result of selection pedigri red rice crosses Silopuk with Fatmawati Superior Varieties using Augmented Design. Silopuk cultivars with red and inlaid rice characteristics while Fatmawati varieties with characteristics of large grain size, high production, high grain number, early age and white rice. The crosses are expected to produce high, large grain size, large amount of grain, maturity and color of brown rice. This research was conducted August-November 2016 at UPT Farm Faculty of Agriculture Andalas University. The genetic material used is the seed of the generation of F3 (F3-5, F3-12, F3-55, F3-95, F3-118, F3-122) derivatives of red rice crosses Silopuk with Fatmawati and the seeds of the two elders as a comparison with the experimental method using Augmented Design. The results of this study indicate the F3 population character number of filled grains per panicle is higher than the two parents with a wide range and other characters are between the two parents. The phenotypic diversity of flowering age characters in the F3-122 family is (2,41) and 1000 weight of pithy grains in the family  F3-5 (2,31) ; F3-55(2,39) and  F3-95 (3,49)  relatively narrow.  However, heritability in the broadest sense and genetic variability for all characters ranges from moderate to high and narrow to broad. Estimated genetic progress with 5% intensity in F3 population has high criteria for all characters (age of flowering, harvest age, plant height, stem length, total tillers, number of productive tillers, total grain / panicle, percentage of filled grains / panicle , total grain weight / clump and weight of filled grain / clump) except panicle length characters and 1000 grain weight of filled grains. Differential selection of population F3 with 10% selection intensity based on 1000 grain weight of pith grain, plant height and total grain weight per hill obtained 31 selected individuals. Selected individuals will be forwarded to the F4 generation

Population F4 is a segregated population the character of certai, so important to know the parameters of genetics. The purpose of our research to determine action of gene and the values expected heritability population F4 (Silopuk X Fatmawati). The research has been from month of October 2017 to February 2018 in land farmer Padang Limau Manis. The research use method experiment without repitition the head to row with analysis Z Skewness and Z Kurtosis. The genetic material of this research is rice seed on the F3 generation from the selection of pedigree crosses between silopuk and Fatmawati superior variety and the other seeds were Silopuk cultivar and Fatmawati superior variety as control. The research data showed that Z test skewness and Z test Kurtosis for whole characters observed were dominant controlled by minor genes. The character age of flowering, plant height, length of panicle and percentage filled grain per panicle were controlled by many gene additive. The broad heritability value for all character observed in the F4 population ranged from 0.01-0.99 with low to high criteria.

A large amount of livestock waste, rotten fruit and vegetable waste and there is a tofu factory that produces tofu dregs around farmer's house at Sidomulyo Village, Stabat District which can be used as an innovation for farmers during the Covid-19 pandemic. The limited activities of farmers in Sidomulyo Village make it difficult for farmers to work in the field because they are worried about the spread of Covid-19 and they try to follow the government's advice to continue to do social distancing and also physical distancing. This has an impact on the income and activities for farmers who daily have to be outside the home to carry out farming activities. To get additional sources of income and positive new activities, especially during the Covid-19 pandemic, this service was carried out by utilizing livestock waste and tofu waste in the environment around Sidomulyo Village by utilizing earthworms in drums to be processed into vermicompost which can be used self (household scale) as well as being developed and marketed for the cultivation of plants such as ornamental plants or horticulture plants.

An F2 population is a segregated population where recombinant characters emergence. To selection these recombinant characters, it is important to know their genetic parameters. The purpose of this study was to determine the action of genes controlling the number of productive tillers, the total number of grains per panicle, the percentage of grain-filled per panicle, weight of one thousand filled grains and total grain weight per hill of F2 generations. Silopuk cultivar with red rice characteristic but has weakness such as long harvest age, high plants, and medium grain size, while superior Fatmawati has early maturity, semidwarf plant n thickness, big grain size, and white grain color. The character can be improved by the plant breeding method using hybridization. The research method used is the experimental method without replication with the head to row method [clump to row] and analyzed using the analysis of Skewness and Kurtosis. The result of the crossing of these varieties is expected to obtain large and heavy grain size, early age as Fatmawati and red rice as Silopuk. Z skewness test results and Z test kurtosis on F tow generation for all characters observed are controlled by many additive genes. The characters that have additive gene action such as plant height, panicle length and total grain size can be used as selection criteria for generation F three.

The problem of fertilizers is often a factor inhibiting agricultural development. This is due to, among other things, the relatively high price of fertilizers, limited supply, decreasing type and quality, which makes it difficult for farmers to obtain fertilizers according to their needs. An alternative to anticipating and overcoming fertilizer shortages is that farmers are encouraged to use organic fertilizers or compost. Based on these considerations, outreach activities to farmers and direct training have been carried out in August-October 2020 in Kwala Bingai Village, Stabat District, Langkat Regency, Sumatera Utara Province. The results obtained are that these activities provide many benefits to farmers such as utilizing agricultural waste for making organic fertilizers so that they are not wasted and can overcome fertilizer scarcity and high fertilizer prices by making simple organic fertilizers. and this activity should be done frequently so that agricultural waste can be utilized.
