Abstract

Indonesia is one country that is rich will flora and fauna which are biological resources. Plant secondary metabolites is a resource that is used for drugs. Besides can be extracted directly from the plant, also can be synthesized to obtain chemical compounds or their derivatives, through the development of cell culture. The impact of the use of synthetic pesticides / chemicals have an impact that is not good for health and cause disruption of the ecological balance. This paper aims to determine the potential utilization of secondary metabolites in plant soursop (Annona murricata) and sugar apple (Annona squamosa) as botanical pesticides to control pests and plant diseases. Plants soursop (Annona muricata) and sugar apple (Annona squamosa) has potential as a pesticide plant in controlling pests and diseases in plants. Results of phytochemical screening on extracts of leaves of the soursop (Annona muricata) found secondary metabolites: alkaloids, flavonoids, terpenoids, coumarin and lactones, anthraquinone, tannins, glycosides, phenols, phytosterols, and saponins, while the detection of the presence of a group of chemical compounds in seed extracts Soursop ( Annona muricata) and sugar apple (Annona squamosa), found secondary metabolites: alkaloids, flavonoids, polyphenols, terpenoids, coumarin, steroids, lactones, anthraquinone, tannins, glycosides, and saponins cyanadin. Natural pesticides are reducing pests, but is not directly Plant Pest Organisms (PPO) pests quickly. Natural pesticide application with the correct dose, can reduce pests, reduce costs and be environmentally friendly.

Abstract

Sugar cane (Saccarum officinarum L.) is a crop that can only be planted in the tropics and having high economic value . The main problems sugar industry in indonesia is low sugar price because of frequent imports sugar, due to technical the low agronomy not done with perfect. The development of sugar cane dry land an option pledged to speed up the process of the quantity , quality , and continuity sugar confection to independence national sugar. The purpose of drafting this paper is to provide information about increased productivity sugar cane in dry land through the application of organic matter and moisturizing synthesis of land ( poliakrilamides ). The role of organic matter very large in boost fertility physical, biology and chemistry the ground and determine productivity land. Organic material has had several excellence namely materials readily obtainable , cheap. But supply always changing and it should be given many times and in large quantitie. Besides organic matter, in agriculture has recommended poliakrilamide as a humectant land can improve the nature of fisikokimia land, reduce the number of irrigation, lost the confusion and production costs plant. The use of poliakrilamide is one of the most effective technology and economical latest identified to finish improve the quality of water required
