The choice of natural fibers as a composite reinforcing material is related to the advantages of being cheap, abundant, renewable, and environmentally friendly. This research was conducted to study the effect of de-lignification treatment on the properties of purun tikus (Eleocharis Dulcis) fiber. Purun tikus fiber has been modified with the alkaline treatment of KMnO4 2% and NaOH 5%. This treatment was mainly applied to improve the physical and chemical properties of purun tikus fiber. Changes in chemical characteristics (water, lignin, cellulose, and hemicellulose), physical (density), mechanical (tensile strength), morphology, and elemental content of purun tikus before and after treated with alkaline were studied. The measurements showed an increase in water content and density while lignin, cellulose, and hemicellulose were decreased. Thus the alkaline treatment of KMnO4 2% and NaOH 5% reduced lignin, cellulose, and hemicellulose of the purun tikus fiber to reduce the size of the fibers, as shown in SEM measurements. There was a change in elemental content after being treated with KMnO4 2% and NaOH 5%. NaOH treatment was better than KMnO4 treatment in terms of removing lignin and hemicellulose in purun tikus fiber. Although the tensile strength of the purun fibers treated with KMnO4 2% and NaOH 5% were lower than untreated, with less lignin, cellulose, and hemicellulose, it is expected that these fibers will blend better in the composite and improved its mechanical properties.

This study aims to examine the effectiveness of the addition of Silane Coupling Agent on physical properties (density, moisture content, thickness expansion, and water absorption) and flexural strength in the manufacture of areca nut peel fiber particle board with urea formaldehyde adhesive. The betel nut peel fiber was alkalized using NaOH for 2 hours, then mashed using a grinding machine until it passed a 50 mesh sieve. The betel nut skin fibers that have passed the sieve are then treated with a solution of Silane Coupling Agent. The concentration variations of the Silane Coupling Agent solution were 0%, 2%, 4%, 6% and 8%. The betel nut peel fiber that has been synthesized with a silane coupling agent solution is then mixed with urea formaldehyde resin in a ratio of 30/70 in weight percent. The particleboard compaction process uses a Hydraulic Cold Press compacting machine with a pressure of 5 bar and a holding time of 120 minutes. The results of this study indicate that the silane coupling agent treatment increases the bond between the matrix and filler as shown in the SEM test on particle boards with 8% silane coupling agent treatment. The results of the particleboard test on density, percentage of moisture content, percentage of thickness development have met the standard of SNI 03-2105-2006. The results of the water absorption test have met the ASTM D 570 standard. The results of the flexural strength test on the SCA 6% variation SNI 03-2105-2006 decorative particle board type 8 and the SCA 8% variation have met the SNI standard 03-2105-2006 structural particle board type 10.5.This study aims to examine the effectiveness of the addition of Silane Coupling Agent on physical properties (density, moisture content, thickness expansion, and water absorption) and flexural strength in the manufacture of areca nut peel fiber particle board with urea formaldehyde adhesive.
