Background – The problem of waste is one of big problems arise from various sectors. Recycling and reusing can be one good solution. Balinese people who still carry out traditions including the event with various arts, one of which is a beautiful offering. This beautiful offering is in the form of sampyan from art coconut leaves which ends as waste. In the past, when Balinese were going to cook, they could use fuel from this dry coconut leaves waste. On The Holidays for ceremonies, there is a 30% increase in waste. Even though this is a ceremonial waste, a balance in the relationship with God/Hyang Widi must be maintained in accordance with the Balinese concept of Tri Hita Karana. This concept is in the form of a balanced relationship towards Hyang Widi/God, to the fellow humans and to the environment that causes happiness. Therefore, waste must be processed. Husks and straw waste from rise field in Bali amounted to 54.65 million tons of GKG, then alot of sawdust waste from wood carving and wood architecture industries. This waste is often burned even though some are used for planting media and fuel. On the other hand, the tourism community and people in Bali produce 829 tons of plastic waste per day. Currently, appreciation of buildings with “Green Architecture” is a concern for tourism and will become of destinations. Thus, it will very possible in Bali. Purpose – provide economic value added for the community, wood workers and farmers and make the world a better place. Findings –Artistic acoustic panel recycled material from plastic bottles and waste of sampyan, sawdust, husks, straw. Originality/value – Acoustic Panel Material and Artistic Acoustic Panels with Balinese Architectural Ornaments is an original. Design/methodology/approach – Recycled plastic waste with the right mixture composition is heated and printed with a hot press machine. In this study, the Transmission Loss test was carried out using an Impedance Tube. Research limitations – Measurement of transmission loss on sheet panels has limitations. Measurements should be developed into room research.
