Abstract

The research was conducted from February-April 2015 in the Laboratory Aquaculture Environmental Quality, Faculty of Fisheries and Marine Sciences University of Riau Pekanbaru. The method used in this study is an experimental method using a Complete Random Design (CRD) with 1 factor, 5 treatments and 3 replications. The treatment used in this experiment is P0:Without application of fertilizer (control), P1:grade N-P-K (20-10-0), P2:grade N-P-K (20-20-0), P3:grade N-P-K (20-30-0) and P4:grade N-P-K (20-40-0). Result showed that the given of phosphat fertilizer with different grade effected to some soil parameter quality. For parameter pH and P-available soil the best treatments is grade N-P-K:20-40-0 (P4). For N-total and C/N ratio the best treatment is grade N-P-K:20-10-0 (P1). For soil organic matter content the best treatment is control (P0). For the parameters of color, texture, bulk density and cation exchange capacity of phosphorus fertilizer with different grade is no effected. Results of measurements of water quality parameters during research that ranged is for pH of water from 3,75 to 6,27 and temperature of water that range from 27-310C. The range of water pH and temperature is still quite good for aquatic organisms .Keyword : phosphat fertilizer, peat soil, soil physical chemistry parameter

Abstract

Security is a condition in which humans or objects feel protected from threatening or disturbing dangers, which in turn will lead to feelings of calm and comfort. Security can be obtained in several ways, one of which is by using and implementing technology. The application of security technology has now developed very rapidly, ranging from conventional to high-tech methods. In terms of security, all methods require a key as validation. This study uses a qualitative approach, this approach is characterized by an in-depth search for information from several sources. Data is collected then processed and analyzed and decisions are made. To collect complete information. This study aims to determine the security management system as well as occupational safety and health and work productivity at PT. Epson Indonesia, to find out the obstacles in implementing security and occupational safety and health at PT. Epson Indonesia and to find out the existing productivity at PT. Epson Indonesia.
