Abstract
This research aimed to determine the physical properties and advantages of cement boards made from sago stem bark waste based on the test results of several parameters according to JIS A 5908 (2003) standard. The results showed that the physical properties of cement board from sago stem bark waste with the addition of the CaCl2 catalyst were good, with the average value of density ranged from 1.19-1.26 gr/cm³, water content 7,67-8,02%, and water absorption after immersion 2 hours 6,03-7.65% as well as after 24-hour immersion 11,62-12,91%, respectively. The averages swelling value of board thickness was 1.62-12,91% after immersion 2 hours and 1.40-3.41% after immersion 24 hours. Furthermore, what sago bark waste in various positions of the tree trunk (tree base, middle and top) can be utilized to manufacture cement board. The board made from sago stem bark waste at the base position with a catalyst CaCl2 6% has the best physical properties and meets JIS A 5908 (2003) standard. Cement board from sago stem bark waste has an excellent waterproof capability and can be used as outdoor materials.

Summary
Alat, Lokasi dan Waktu Penelitian Bahan yang digunakan dalam penelitian ini adalah limbah kulit batang sagu (Metroxylon Sp.). Ukuran papan semen yang dibuat yaitu 30 cm x 30 cm x 1,2 cm (pxlxt) dengan kerapatan sasaran 1,2 gr/cm. Setelah itu dilanjutkan dengan pembuatan lembaran adonan (mat) melalui pencampuran antara semen, kulit batang sagu, dan air serta katalis, (dengan perbandingan semen : partikel : air sebesar 2,5 : 1 : 1,25); kemudian. Sifat Fisis Dan Keunggulan Papan Semen Dari Limbah Kulit Batang Sagu Pengujian sifat fisis papan semen mengikuti standar JIS A-5908 (2003) yang meliputi : kerapatan, kadar air, daya serap air, dan pengembangan tebal. Pola pemotongan contoh uji seperti pada Gambar 2. Analisis data menggunakan metode Rancangan Acak Lengkap dengan 2 perlakuan yaitu posisi kulit batang sagu (pangkal, tengah ujung) dan presentase katalis CaCl2 (2%, 4% dan 6%). Contoh uji daya serap air dan pengembangan tebal berukuran 5 cm x 5 cm. Pola Pemotongan Contoh Uji Papan Semen Menurut JIS A-5908 (2003)
