Healthy Chips from Banana Stem Waste

Post date: Friday, February 17, 2023 - 09:22

A team of UNY students consisting of Yustina Rahma Sari, Linda Oktafianingsih, Brina Gamelisa, Kiki Adisti, Rahayu, Tiar Rahmasanti, Arief Kurniawan, Fani Maulana, Muhammad Raihan A and Tria Adelia succeeded in processing banana stems into chips. "After harvesting bananas, banana tree trunks are cut down and rotted. People mostly have not used banana stems, so the stems have no economic value. Therefore, we are interested in making food innovations from banana stems," said Yustina Rahma Sari.

To give a wider impact, the UNY student team has held training on making banana stem chips for women in Bojong Village, Purworejo Regency.

Sandiana Uno Appreciates Corncob Waste Crafts by UNY Students

Post date: Tuesday, July 26, 2022 - 11:51

Corn (Zea Mays L) is a plantation crop that thrives in Indonesia and can be harvested 2-3 times a year. The corn harvest period is the most awaited because farmers benefit from their crops. However, most of the corn is sold a whole. The corn cobs are only burned and even thrown away as waste. The problem is that corncob waste is easily decomposed and causes an unpleasant odor. This problem has prompted Ade Kurniawan, a student of craft education at UNY, to process corncob waste into handicraft products that are sustainable, eco-friendly, and encourage zero waste implementation. Some products that have been successfully developed are bed lamps, tissue holders, wall ornaments, and decorative lights.

Ade is not alone in working on various handicraft products made from corn cob... Read More ...
