Abstract: Agricultural waste in the form of rice straw is a potential local raw material that can be processed into organic fertilizer and bokashi. At harvest time, this rice waste is very abundant and has not been utilized optimally. The use of straw in relation to providing nutrients and soil organic matter is remodeling it into compost. EM4 activator is a material that contains several microorganisms and helps speed up the compostingprocess. The purpose of this study was to utilize rice straw waste with EM4 activator, to measure the physical properties of the bokashi fertilizer, temperature, color, smell, texture, pH, and length of time to make bokashi. This research was conducted in the area of the State Agricultural Polytechnic Production Laboratory of Samarinda. This research was conducted for 3 months starting from October 20 to December 20, 2017, including preparation, making bokashi, data collection andreporting. The results of the research on making bokashi fertilizer from rice straw (Oryza sativa L.) using activator EM4 can be seen that the observation of bokashi fertilizer was carried out until the 21st day and it looks ripe with observations of temperature 28 C °, pH 7, brown color. blackish andodorless.
