Most of Indonesia’s population works in agriculture, so Indonesia is often referred to as an agricultural country. According to 2013 BPS Tuban District data, Jenu Subdistrict itself is the fifth largest corn producing area in Tuban with a production of 39,440 tons / year. This is supported by the large number of workers in Tuban regency in agriculture, which accounted for 50% of the total working age population in Tuban district.
This certainly leaves waste in the form of corncob, corn stalks and leaves, and corn husk. So far, the utilization of corn agricultural waste in Tuban is still not optimal. Corn farm waste left on the land, only burned. This of course can increase air pollution caused by burning corn waste.Reduction of corn plant waste by farmers around PT Pertamina TBBM Tuban (ring 1) by burning, will be able to disrupt safety (safety) because PT Pertamina Tubb TBBM is a very dangerous area and has the potential for fire with the spread of temperature increases around Tubb TBBM. Therefore, a transfer of corn plant waste activities is needed to become an added value for both the community and PT Pertamina TBBM Tuban
The Sepuluh Nopember Institute of Technology (ITS) is a leading university in the field of science and technology in Indonesia. ITS is trusted by PT Pertamina TBBM Tuban to carry out Corporate Social Responsibility (CSR) programs related to the Utilization of Corn Waste into Organic Fertilizer in Tasikharjo Village, Jenu Sub-District, Tuban.Dr Setiyo Gunawan, Chair of the CSR team, said that this CSR program is a company’s contribution to the sustainable development goals by minimizing the negative impact and maximizing the positive impact on all stakeholders. The CSR program began with the production of organic fertilizer production houses from corn agricultural waste and a 1 hectare planting test (maize, brambang and tomato) in the land of the Village Owned Enterprises (BUMDES) in Tasikharjo village.At present the majority of Tuban people use inorganic / chemical fertilizers for their agricultural land, this chemical fertilizer has several disadvantages, among others, resulting in residues in the soil so that the soil can become hard, unwise use can damage the soil, expensive and hygroscopic “With these shortcomings, organic fertilizer can be a good alternative as part of the use of chemical fertilizers. “Organic fertilizers are safer, materials are easier to obtain, more microorganism elements, increase soil fertility and are able to maintain nutrients (soil is not hard),” added Dr. Sri Rahmania Juliastuti interrupted during visits to maize, brambang and tomato trials using fertilizers. organic (Sunday, May 12, 2019).
Furthermore, Sumaji, Chair of Tasikharjo BUMDES, thanked PT Pertamina TBBM Tuban and ITS for the CSR program that has proven beneficial to the community of Tasikharjo village. And expect CSR to be sustainable in order to realize the goal of the community as an educational tourism village in Tuban.
