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.

The Covid-19 pandemic around the world has caused many problems in various sectors. The implementation of lockdown and large-scale social restrictions made it difficult to distribute foodstuffs from producers to consumers and also to deliver humanitarian aid. This made the inequalities even wider. The pandemic also resulted in an economic crisis which resulted in increased unemployment so that many people were starving because they could not afford food. This certainly hinders the realization of the Sustainable Development Goals, especially No Hunger and Reduced Inequalities points. In West Java, reviving the Beas Perelek tradition is a solution. However, a question arises whether this tradition can be applied in a time of the Covid-19 pandemic like today. The objective of this research is to describe the implementation and analyze the potential for sustainability of Beas Perelek in the society of West Java also to provide strategic elaboration recommendations to achieve sustainable development goals during the Covid-19 pandemic.To achieve the objective, this research using qualitative methods by collecting data from literature studies. The sustainability analysis technique uses the rapfish-MDS and the SWOT method to formulate an elaboration strategy of Beas Perelek. The result of the research showed that the tradition of Beas Perelek had benefits in reducing hunger and inequalities in society. The result of the research shows the continuity of the tradition of Beas Perelek in the good category with continuing status. To increase the implementation of Beas Perelek during the pandemic, it is necessary to carry out several elaboration strategies such as being revitalized into an economic institution, using technological innovations, and making special policies that regulate the implementation of the Beas Perelek.
