      Abstract
      Lignin berpotensi sebagai aditif Flame Retardant (FR) yang ramah lingkungan karena dapat memanfaatkan limbah dan berasal dari bahan terbarukan. Lignin bersifat tidak larut air, sehingga diperlukan modifikasi melalui proses sulfonasi menjadi lignosulfonat agar mudah dalam pengaplikasiannya. Lignin dan lignosulfonat dari kayu Eukaliptus diaplikasikan pada papan partikel pelepah pinang berperekat asam sitrat-sukrosa. Penelitian ini bertujuan menganalisis pengaruh penambahan lignin dan lignosulfonat sebagai aditif terhadap sifat ketahanan api dan fisis mekanis papan partikel pelepah pinang berperekat asam sitrat-sukrosa. Lignin dan lignosulfonat dari kayu Eukaliptus diaplikasikan pada papan partikel pelepah pinang berperekat asam sitrat-sukrosa. Pengujian papan partikel meliputi uji ketahanan api, sifat fisis dan mekanis. Hasil penelitian menunjukkan bahwa kehilangan berat papan partikel setelah diuji bakar torch menurun setelah ditambahkan lignin dan lignosulfonat. Penambahan larutan lignin dan lignosulfonat tidak berpengaruh signifikan terhadap sifat ketahanan api papan partikel setelah diuji dengan UL-94. Pengujian sifat fisis mekanis papan partikel yang mengacu pada standar Japanese Industrial Standards (JIS) A 5908-2003 menunjukkan bahwa penambahan lignosulfonat meningkatkan sifat fisis dan mekanis papan partikel walaupun secara keseluruhan belum memenuhi standar JIS A 5908-2003.
       
      Lignin has the potential as an environmentally friendly Fire Retardant (FR) additive in biocomposite manufacturing. Lignin is water-insoluble, which requires modification of the solubility through a sulfonation process to become lignosulfonate for easy application. Lignin and lignosulfonates from Eucalyptus wood were applied as filler to the areca nut frond particleboard bonded citric acid-sucrose. This research aims to analyze the effect of adding lignin and lignosulfonate as additives on the fire resistance and mechanical-physical properties of the areca nut frond particleboard with citric acid-sucrose adhesive. Particleboard testing includes fire resistance tests and physical and mechanical properties. The results showed that the weight loss of particle board after the torch-burning test decreased after adding lignin and lignosulfonate. The addition of lignin and lignosulfonate solutions did not have a significant effect on the fire resistance properties of particleboard after being tested with UL-94. Testing of the physical and mechanical properties of particle board referring to the Japanese Industrial Standards (JIS) A 5908-2003 standard shows that the addition of lignosulfonate improves the physical and mechanical properties of particle board even though overall it does not meet the JIS A 5908-2003 standard.
