Laboratory-scale manufactured hardboard made of Saccharum Sponaneoun Grasses (SSG), Empty Oil-palm Bunches (EOPB), and andong bamboo is potentially developed. However, initial experiment shows the hardboard did not meet Japanese Industrial Standard (JIS) and International Standard Organization (ISO) for hardboard. This paper observes modification of the hardboard to satisfy the standards. Modification includes adding alkali concentration during pulp cooking and changing the additives

Fiber mixture of SSG pulp and andong/betung bamboo pulp was cooked in 10.5% alkali concentration; and 12% alkali concentration for EOPB pulp. Additives composition used were tannin-resorcinolformaldehyde/TRF adhesive, alum, and activated charcoal; without wax emulsion. The mixture of SSG pulp (50%) + EOPB pulp (50%) was the most prospective for hardboard, followed by SSG pulp (100%) solely; SSG pulp (50%) + andong bamboo pulp (50%); and SSG pulp (50%) + betung bamboo pulp (50%) as the lowest prospects. The leastprospective fibrous material (betung bamboo) are expectedly be improved by using more TRF adhesive, nano-size activated charcoal and cross-linking agents. ABSTRAK Papan serat (HB) dari campuran Rumput Gelagah (RG), Tandan Kosong Kelapa Sawit hardboard (TKKS) dan bambu andong berpotensi untuk dikembangkan. Namun, percobaan pendahuluan menunjukkan HB tersebut tidak memenuhi persyaratan produk HB dari (JIS) Japanese Industrial Standard dan (ISO). Tulisan ini mempelajari modifikasi pembuatan HB agar International Standard Organization memenuhi standar produk tersebut. Modifikasi yang dilakukan meliputi penambahan konsentrasi alkali dalam pemasakan pulp dan merubah komposisi perekat. Hasil penelitian menunjukkan kualitas HB modifikasi meningkat dan mampu memenuhi persyaratan standar JIS dan ISO. Campuran serat pulp RG dan bambu andong/betung dimasak dengan konsentrasi alkali 10,5% dan 12% untuk serat dari TKKS. Campuran perekat yang digunakan adalah tannin-resorsinol-formaldehida (TRF), alum (tawas) dan emulsi lilin. Campuran serat yang paling banyak memenuhi standar adalah RG pulp (50%) + TKKS pulp (50%), diikuti RG pulp (100%), TKKS pulp (50%) + pulp bambu andong (50%), RG pulp (50%) + pulp bambu betung (50%). Serat yang masih kurang prospektif (bambu betung) diharapkan dapat
