Judul: Oil Palm Fronds Particleboard Bonded with Phenol Formaldehyde and Molasses Adhesive
Abstrak: The utilization of oil palm fronds to be converted as particleboard was considered effective in preserving the environment. The addition of molasses to adhesive mixtures with phenol-formaldehyde (PF) was carried out as an effort to reduce the use of PF adhesive. This research aims to produce particleboard with high-quality and eco-friendly from oil palm fronds and to analyze the effect of adding molasses to PF adhesive on the quality of particleboard. This research method uses 5 levels of PF: molasses adhesive composition, namely 100:0, 75:25, 50:50, 25:75, and 0:100 (wt%). The target density of particleboard is designed to be 0,8 g/cm³ with dimensions of (30×30×0.6) cm³. The adhesive content used is 16% with a compression temperature of 180 °C for 10 minutes. Overall, the results of testing showed that the density, moisture content, thickness swelling, and MOE of the particleboard in this study had met the standard of SNI 03-2105-2006, but in the tests of MOR and IB only the composition of PF: molasses 100:0, 75:25, and 50:50 which had met the standard of SNI 03-2105-2006.

Judul: Papan Partikel Dari Pelepah Kelapa Sawit Menggunakan Perekat Asam Sitrat dan Molase
Abstrak: Pelepah kelapa sawit merupakan biomassa kelapa sawit yang biasanya tidak dimanfaatkan secara optimal, pelepah kelapa sawit memiliki kandungan lignoselulosa yang berpotensi untuk dijadikan papan partikel dan ketersediannya yang cukup melimpah.Penelitian ini bertujuan menghasilkan papan partikel yang ramah lingkungan tanpa menggunakan bahan kimia berbahaya. Selain itu, menganalisis pengaruh kadar perekat dengan menggunakan asam sitrat dan molase terhadap karakteristik sifat fisis dan mekanis papan partikel. Papan dibuat dengan kerapatan target 0,8 g/cm³ dan ukuran 30 x 30x 0,6 cm menggunakan kempa panas suhu 200°C selama 10 menit dengan tekanan 5 Mpa. Pengujian sifat fisis dan mekanis papan partikel mengacu pada standar SNI 03-2105-2006 (kerapatan, kadar air, daya serap air, pengembangan tebal, MOE, MOR, dan keteguhan rekat). Hasil penelitian ini menunjukan kadar perekat berpengaruh nyata terhadap karakteristik sifat fisis dan mekanis papan partikel Semakin tinggi kadar perekat yang ditambahkan mampu meningkatkan sifat fisis dan mekanis pada papan plafon yang dibuat., Palm fronds are palm biomass that is usually not used optimally, palm fronds have lignocellulose content that has the potential to be used as a particleboard and its availability is quite abundant. This study aims to produce environmentally friendly particle boards without the use of harmful chemicals. In addition, it analyzes the effect of adhesive levels using citric acid and molasses on the characteristics of the physical and mechanical properties of particle boards. The board was made with a target density of 0,8 g/cm³ and a size of 30 x 30x 0,6 cm using a heat felt of 200°C for 10 minutes with a pressure of 5 Mpa. Testing of the physical and mechanical properties of particle boards refers to the standard SNI 03-2105-2006 (density, moisture content, water absorption, thickness swelling, MOE, MOR, and internal bounding). The results of this research show that the adhesive content has a significant effect on the characteristics of the physical and mechanical properties of composite ceiling boards. The higher the adhesive content added is able to improve the physical and mechanical properties of the ceiling board made.
