Abstract
The increase in plastic waste, especially from PP bottles, has become a serious environmental problem due to low recycling rates and high use of single-use plastics. One potential solution is to utilize this waste as raw material for particle boards with the addition of lightweight and renewable bamboo powder. This study analyzes the effect of variations in compaction pressure and holding time on the physical and mechanical properties of particle boards based on plastic waste and bamboo powder using the DEAR method. Samples were made at pressures of 10 MPa and 30 MPa and times of 60 and 120 minutes, then tested for density, moisture content, thickness expansion, MOR, and MOE. The results show that pressure has a more dominant effect than holding time. The combination of 30 MPa for 60 minutes (sample Bb) gave the best results with a density of 0.790 g/cm³, MOR 53.810 kgf/cm², MOE of 11.140 kgf/cm², and the highest MRPI value of 6.480, while the lowest value was found in sample Aa (10 MPa, 60 minutes) with an MRPI of 0.211. In conclusion, the combination of high pressure and moderate holding time is the most optimal condition for producing strong, dense particle boards that are resistant to moisture. This study contributes to the development of alternative materials based on plastic waste and supports sustainable waste reduction efforts. Keywords: Particleboard, DEAR, MRPI.

| Additional Information: | Peningkatan limbah plastik, terutama dari botol berbahan PP, menjadi masalah lingkungan serius akibat rendahnya daur ulang dan tingginya penggunaan plastik sekali pakai. Salah satu solusi potensial adalah memanfaatkan limbah tersebut sebagai bahan baku papan partikel dengan tambahan serbuk bambu yang ringan dan terbarukan. Penelitian ini menganalisis pengaruh variasi tekanan kompaksi dan waktu penahanan terhadap sifat fisik serta mekanik papan partikel berbasis limbah plastik dan serbuk bambu menggunakan metode DEAR. Sampel dibuat pada tekanan 10 MPa dan 30 MPa serta waktu 60 dan 120 menit, lalu diuji berdasarkan densitas, kadar air, pengembangan tebal, MOR, dan MOE. Hasil menunjukkan tekanan berpengaruh lebih dominan dibanding waktu penahanan. Kombinasi 30 MPa selama 60 menit (sampel Bb) memberikan hasil terbaik dengan densitas 0,790 g/cm³, MOR 53,810 kgf/cm², MOE 11,140 kgf/cm², serta nilai MRPI tertinggi 6,480, sedangkan nilai terendah terdapat pada sampel Aa (10 MPa, 60 menit) dengan MRPI sebesar 0,211. Kesimpulannya, kombinasi tekanan tinggi dan waktu penahanan sedang merupakan kondisi paling optimal untuk menghasilkan papan partikel yang kuat, padat, dan tahan terhadap pengaruh kelembapan. Penelitian ini memberikan kontribusi terhadap pengembangan material alternatif berbasis limbah plastik dan mendukung upaya pengurangan limbah secara berkelanjutan.
