Abstract
Organic fertilizer consists of organic materials derived from plants or animals that have been treated through an engineering process, to improve the physical, chemical, and biological properties of the soil. This research studied the manufacture of organic fertilizer made of raw sawdust and cow dung. The microorganism used to decompose the organic matters was Effective Microorganisms 4 (EM4). The purpose of this study was to determine the effect of composition and composting time on fertilizer quality. The composition of fertilizer was varied with the mass of sawdust and cow dung, namely P (150 g + 50 g), Q (300 g + 50 g), and R (450 g + 50 g), with composting time period of 1 week, 2 weeks, and 3 weeks. The quality of fertilizer was tested by observing the growth of test plants. From the observation, the best growth of the plant was obtained after 14 days,i.e 9.98; 8.96; 8.23; and 8.28 cm.
