Abstract

3-Dimensional Roll Work technology training by processing waste paper into high-value handicraft products has been carried out in Nagari Lareh Nan Panjang, Padang Pariaman Regency. Most of the productive age groups in this area were unemployed women who depend on their husband's income for a living. In other hand, the activities of women's farmer groups, youth groups and (Family Welfare Movement) PKK were not productive. This activity aims to foster and empower community groups, especially women, in managing and processing paper waste into high selling value products with 3-Dimensional Roll Work technology that can be used as business opportunities so as to increase household income. The activity began with counseling on the dangers of paper waste for health and the environment, and continued by 3-dimensional Roll Work training. The indicator of the achievement of the targeted community service program was the management and processing of paper waste where each participant can produce quality handicraft products, namely key chains and accessories, while for other handicraft products, it was continued for group activities such as tissue, accessories, and cake boxes. This activity can be used as a sustainable empowerment effort through increasing community participation, self-financing and community self-help so as to create economically independent women in Nagari Lareh Nan Panjang.

Abstract

Paper waste is the most common waste generated from academic activities on the Andalas University campus. So far, paper waste is allowed to accumulate and then sold by cleaners to waste collectors or burned. This activity aims to increase women's resources and potential through Qulling Paper technology with promising business opportunities, especially for cleaning workers. This activity was carried out from July to September 2022, with the target participants being cleaners with direct contact with paper waste. The method used is counseling about the dangers of paper waste to the environment and health, which ends with discussions and interviews to determine the level of knowledge of cleaning workers about the management and processing of paper waste. The activity continued with paper waste processing training through paper quilling technology by practicing directly until the participants could produce a craft product. Mentoring activities for participants are also carried out by guiding them until they are skilled at producing craft products worth selling. In this training activity, all activity participants can produce handicraft products that have high selling value and are economical. Paper waste processing training for cleaners is one of the most appropriate solutions for reducing the amount of paper waste on the Andalas University campus and, at the same time, improving skills. It is hoped that this activity can increase knowledge and skills and reduce the amount of paper waste in the Andalas University campus environment.
