The effect of immersion time in the water, starch and lignin content physical and mechanical properties of Ampel bamboo (Bambusa vulgaris Schard)
The studied effect of immersion time in the water on physical and mechanical properties of ampel bamboo had been studied  at the Forest Products Research and Development Center Bogor. Round Bamboo of ampel species (Bambusa vulgaris Schard) a length of 50 cm was immersed in running water, stagnant and in the sludge for 7, 14, 21 and 28 days. Then the changes in starch and lignin content, physical and mechanical properties were evaluated. The physical properties studied were evaluated density and moisture content, while mechanical properties were bending and parallel tensile strength of fiber. The results showed that the media and immersion time significantly affect the density and moisture content, but did not affect the physical and mechanical properties. Increased starch content in a variety of treatments, especially on immersion in water, otherwise the lignin content decreases, causing a decrease in the nature of Modulus of Elasticity (MOE) and Modulus of Rupture (MOR). Immersion in stagnant water better than by soaking in the mud and in running water.
Keywords: Bambusa vulgaris Schard, media, immersion time, physical and mechanical properties

ABSTRAK
Penelitian pengaruh waktu perendaman dalam air terhadap sifat fisik dan mekanik bambu ampel (bambusa vulgaris) telah dilakukan di Pusat Penelitian dan Pengembangan Hasil Hutan Bogor. Bambu bulat berukuran panjang 50 cm direndam dalam air mengalir, tergenang dan lumpur selama 7, 14, 21 dan 28 hari, kemudian diamati perubahan kadar pati,diuji sifat fisik dan mekaniknya. Sifat fisik yang diteliti adalah kerapatan dan kadar air, sedangkan sifat mekanik adalah keteguhan lentur dan tarik sejajar serat. Hasil penelitian menunjukkan bahwa media dan waktu rendaman berpengaruh nyata terhadap kerapatan dan kadar air, tetapi tidak berpengaruh terhadap sifat fisis dan mekanis bambu yang diteliti. Kadar pati meningkat pada berbagai perlakuan terutama pada rendaman dalam air mengalir, sebaliknya kandungan lignin menurun sehingga menyebabkan penurunan sifat Modulus elastisitas (MOE) dan keteguhan lentur maksimum (MOR). Perendaman dalam air tergenang lebih baik dibandingkan dengan cara perendaman dalam lumpur maupun dalam air mengalir.
