One of the factors that determine the quality of chilli pepper seedlings is fertility of growing of medium. Fertility of growing medium can be incrase with fertilization, by using of Urea fertilizer and of KCl fertilizer be expected to increase chilli pepper seedlings. This research was carried out in Dewi Sartika, Rantau Selatan Sub District of West Labuhanbatu, East of nort Sumatera Utara in March until June 2015 using randomize complete block design with two factors. The first factor used Urea fertilizer (0, 1.5, 2.5, 3gr/polibag), and the second factor used of KCl fertilizer (1, 2, 3gr/polibag). Parameter observed were plant height, stem diameter, weight of the fruit crop samples, and heavy fruit perplot. From the research of Urea fertilizer very significant effect on all parameters of KCl fertilizer very significant weight of the fruit crop samples and weight fruit/plot. Interaction of Urea fertilizer and KCl fertilizer significant weight of the fruit crop samples and very significant weight of fruit/plot. The result from this experimental were obtained in the treatment of Urea fertilizer Urea fertilizer application (U3) and of KCl fertilizer application (K3). Keywords : Urea fertilizer, KCl fertilizer, Chili pepper seedlings.

The population of cattle in the village of cliffs of high rank has enormous potential. This capacity is very good if used in the manufacture of organic fertilizer because in general cow dung waste has not been processed and utilized properly by the people of the village of cliffs of high rank. Agricultural activities of the high-ranking cliff village community which continuously result in the use of chemical fertilizers continue to increase, thus the use of organic fertilizers is an alternative in reducing community dependence in using chemical fertilizers in agriculture. The objectives of this community service are, 1) to carry out socialization and training to the community, 2) to understand more about the manufacturing procedure, the tools used, the materials used, how to use them on plants, and the benefits of manure. cows as an environmentally friendly organic fertilizer. The results of this dedication show that the manufacture of organic fertilizer requires the addition of materials, namely sawdust, rice water, coconut water, and brown sugar solution with the aim of increasing the nutrients of organic fertilizer. The application of organic fertilizers on agricultural land can reduce the manufacture of chemical fertilizers, but can improve the nutrients in the soil. Abundant cow dung is a great result for fixing nutrients in soils that are already highly dependent on chemical fertilizers. Therefore, the manufacture of organic fertilizers needs to be continuously disseminated to the community, especially farmers in rural areas who lack information and technology. This is possible through activities, knowledge and training. This service program is carried out using two methods, namely: face-to-face socialization, the practice of making organic fertilizers.

This community service activity is carried out through the use of liquid organic fertilizer made from bamboo shoots. Bamboo shoots are a food ingredient that is quite popular in the community. Impressed with vegetables, bamboo shoots, which are often known as bung (Javanese), have been used by rural people since ancient times as a cooking ingredient, especially for making vegetables. Apart from being used as vegetables, bamboo shoots can be used to make liquid organic fertilizer (POC). In addition, bamboo shoots contain the hormone giberellin, so that they can stimulate plant growth quickly. Because bamboo shoots contain gibberellins, liquid organic fertilizer from bamboo shoots functions to stimulate plant vegetative growth. Therefore efforts are made to increase knowledge in the community so that later it can reduce dependence or farmers on the use of chemical fertilizers.
