Abstract
Objective of this research is to: 1) utilize agricultural waste, specifically cassava rhizome types in the eastern region, 2) study the production process of activated carbon with suitable material properties, and 3) create value-added odor-absorbing products through three different design processes. The research methodology is qualitative, involving laboratory research and development, data analysis, summarization, product prototype testing, and production. The research findings are as follows: 1) Cassava rhizome types, a form of agricultural waste, have potential for value-added applications. 2) The activated carbon production process consists of two steps: charcoal preparation and subsequent stimulation to create micropores. Chemical stimulation is the most effective method, resulting in activated carbon with high porosity and strong odor-absorption capabilities. 3) Odor-absorbing products were developed: car air fresheners containing 60 % activated carbon powder and 40 % plaster, molded into a cactus shape (50x50x80 mm); kitchen deodorizers containing 70 % activated carbon powder and 30 % plaster, molded into a hexagonal shape (150x125x40 mm); and deodorizing soap containing 20 % activated carbon powder and 80 % glycerin soap base, molded into a square shape (50x50x20 mm).
