Sendangmulyo Village is one of the villages in Bulu District, Rembang Regency, which is located on the border of Blora Regency. One of the agricultural commodities that are widely cultivated in Sendangmulyo Village is corn. However, the use of this corn commodity is generally still limited to the seeds, while the cob is discarded and instead pollutes the environment. Seeing this problem, the IPB Rembang KKN-T group held a webinar as well as the practice of making silage made from corn cobs. The purpose of this program is to provide an understanding to the people of Sendangmulyo Village regarding the utilization of corncob waste into silage. The webinar was held online through the zoom meeting platform for the general public, then continued with the practice of making silage together for the people of Sendangmulyo Village. The materials used in making silage are corn cobs and elephant grass that have been chopped, bran, molasses, and water. Quality silage can be seen from physical characteristics such as color, texture, aroma, and the presence of mushrooms. Based on the results of observations, the silage made has a light brown color, is not runny and has a slightly sour smell but there is still a little fungus so that the silage results can be classified as poor. The implementation of the webinar and the direct practice of making silage from corn cobs received a positive response from the webinar participants and the people of Sendangmulyo Village. The disadvantage of this program is that in the practice of making silage the number of participants is limited due to the PPKM period so that the delivery of information has not been widely conveyed.
