Zul Rahman Arief. Karakteristik Papan Semen dari Limbah Kertas Kardus dengan Penambahan Katalis Kalsium Klorida. Dibimbing oleh Tito Sucipto, S.Hut, M.Si dan Luthfi Hakim, S.Hut, M.Si.
ABSTRAK
Papan semen berpotensi besar sebagai bahan substitusi kayu untuk konstruksi bangunan. Tujuan penelitian adalah mengevaluasi kualitas papan semen berupa sifat fisis dan mekanis papan semen serta ketahanannya terhadap serangan rayap. Papan dibuat dengan ukuran 30 cm x 30 cm x 1 cm dan kerapatan 1 g/cm3 pada variasi komposisi semen : fiber : air dengan penambahan katalis kalsium klorida. Sifat fisis dan mekanis papan semen yang memenuhi standar JIS A 5414-1993 adalah kerapatan, daya serap air dan MOE sedangkan kadar air, pengembangan tebal dan MOR tidak memenuhi standar. Nilai kerapatan papan semen dengan menggunakan katalis kalsium klorida yang memenuhi standar adalah 1,27 g/cm3-1,29 g/cm3, daya serap air 5,30%-22,31%, MOE 468,48 kg/cm2-568,33 kg/cm2, sedangkan kerapatan papan semen tanpa katalis berkisar 1,13 g/cm3-1,67g/cm3, daya serap air 9,95%-16,83%, MOE 131,73 kg/cm2-196,95 kg/cm2. Papan semen memiliki keawetan yang cukup tinggi terhadap serangan rayap. Papan semen yang memiliki kualitas terbaik berdasarkan pengujian sifat fisis, mekanis dan ketahanan terhadap serangan rayap terdapat pada komposisi perbandingan semen : fiber : air (1,75 : 1,75 : 1,25) dan penambahan katalis kalsium klorida.
Kata kunci: papan semen, limbah kardus, kalsium klorida, sifat fisis dan mekanis, keawetan

ABSTRACT
Cement board holds great potential as a wood substitute material for building construction. The research objective was to evaluate the physical and mechanical properties of cement board as well resistance to termite attack. Boards made with size 30 cm x 30 cm x 1 cm and a density 1 g/cm3 under various composition of cement : fiber : water ratio with addition of calcium chloride catalysts. Physical and mechanical properties of cement board that fulfill the standards were the density, water absorption and MOE, while the moisture content, thickness swelling and MOR not fulfill the standards. The value density of the cement board using calcium chloride catalyst that fulfill the standards is the ranges from 1,27 g/cm3- 1,29 g/cm3, water absorption 5,30%-22,31%, MOE 468,48 kg/cm2-568,33 kg/cm2 while the cement board without catalyst density ranges from 1,13 g/cm3-1,67 g/cm3, water absorption 9,95%-16,83%, MOE 131,73 kg/cm2-196,95 kg/cm2. The cement board has a relatively high durability against termite attack. Cement board that has the best quality based on the testing of physical properties, mechanical properties and resistance to termite attack there on the composition ratio of cement : fiber : water (1,75 : 1,75 : 1,25) and calcium chloride catalyst.
Key words: cement board, corrugated paper waste, calcium chloride, physical and mechanical properties, durability
