Abstract

Penelitian sifat fisika meliputi kerapatan, kadar air, penyerapan air dan pengembangan tebal dan sifat mekanika meliputi keteguhan lentur (MoE) keteguhan patah (MoR) serta  pengurangan tebal akibat tekanan. Rancangan Percobaan Yang digunakan adalah rancangan acak lengkap (RAL) dengan 3 perlakuan yaitu 100% pelepah kelapa sawit; 100% kulit durian dan  50% pelepah kelapa sawit : 50% kulit durian dengan 3 kali ulangan. Standar yang digunakan untuk perbandingan  yaitu SNI–03– 2104-1991-A. Hasil penelitian adalah sebagai berikut : Sifat Fisika yaitu kerapatan rata-rata antara 100% Pelepah Kelapa Sawit, 100% Kulit Durian dan 50% Pelepah kelapa sawit : 50% kulit Durian berturut-turut adalah 0,90 gr/ cm3, 0,91 gr/ cm3, 0,81 gr/ cm3, Kadar air rata-rata antara 100% Pelepah Kelapa Sawit, 100% Kulit Durian dan 50% Pelepah kelapa sawit : 50% kulit Durian berturut-turut adalah 7,37%, 6,59%, 7,08%, Penyerapan air rata-rata antara 100% Pelepah Kelapa Sawit, 100% Kulit Durian dan 50% Pelepah kelapa sawit : 50% kulit Durian berturut-turut adalah 49,51%, 44,99%, 50,11%, Pengembangan tebal rata-rata antara 100% Pelepah Kelapa Sawit, 100% Kulit Durian dan 50% Pelepah kelapa sawit : 50% kulit Durian berturut-turut adalah 1,67%, 2,04%, 3,44%, Kerapatan, kadar air, penyerapan air dan pengembangan tebal tidak berpengaruh nyata. Sifat Mekanika yaitu Keteguhan lentur (MoE) rata-rata antara 100% Pelepah Kelapa Sawit, 100% Kulit Durian dan 50% Pelepah kelapa sawit : 50% kulit Durian berturut-turut adalah 7.350,68 kg/cm2, 3.590,43 kg/cm2, Keteguhan patah (MoR) rata-rata antara 100% Pelepah Kelapa Sawit, 100% Kulit Durian dan 50% Pelepah kelapa sawit : 50% kulit Durian berturut-turut adalah 11,82kg/cm2, 8,66kg/cm2, 4,53 kg/cm2Pengurangan tebal akibat tekanan rata-rata antara 100% Pelepah Kelapa Sawit, 100% Kulit Durian dan 50% Pelepah kelapa sawit : 50% kulit Durian berturut-turut adalah 8,92 %, 10,01 %, 9,92 %, Keteguhan patah (MoR) berpengaruh nyata sedangkan keteguhan lentur (MoE) dan pengurangan tebal akibat tekanan tidak berpengaruh nyata.Key word : Kerapatan, Kadar Air, Penyerapan Air, Pengembangan Tebal, Keteguhan Lentur (MoE), Keteguhan Patah (MoR) dan Pengurangan Tebal Akibat Tekanan

Abstract

This research aims to get both the active chemical compounds of galam’swood vinegar which functions as antifungi and anti-termite usage and the process or factors influence it. Another purpose of the research is to find how effective the active compounds are toward wood destroyer organisms, either termite or fungus. Anti-termite assay is done by using a method of the mortal percentage of termites in sort of Cryptotermes cynocephalus Light and a method of growth inhibition of Schizopyllum commune fungus by wood vinegar for antifungi assay. To find the influence within the treatment of wood vinegar production process (the raw material condition and distillation), wood vinegar concentration level concerning with the active compounds of antifungi and anti-termite, each of treatments is analyzed using statistical analysis with CRD. Wood vinegar is a natural organic liquid resulting from the condensation of smoke in the process of making charcoal. Generally, the result shows that galam’s wood vinegar have a potential used as natural wood preservative material. For this kind of utility, the vinegar can either be spontaneously used or be reproduced by a distillation process with 50% concentration. Galam’swood vinegar contains some components, namely phenolic, acid and carbonyl.

Abstract

The aim of this research is to determine the quality of biopellets made from unproductive rubber sawdust and empty oil palm bunch waste including water content, density, ash content, volatile matter, bound carbon, calorific value and to find out which biopellet quality composition is best suited. SNI 8021:2014. The test results showed that the water content of all treatments met the standards, while other parameters (density, ash content, volatile matter, bound carbon) did not meet the standards. Meanwhile, for the calorific value, only treatment A (100% rubber wood) can meet the standard, where based on statistical tests this treatment is very significantly different from other treatments. These results show that biopellets made from 100% rubber wood are biopellets with the best treatment. The research results showed that biopellets consisted of composition A (100% rubber wood); composition B (75% rubber wood + 25% empty oil palm bunch); composition C (50% rubber wood + 50% empty oil palm bunch); composition D (25% rubber wood + 75% empty oil palm bunch); composition E (100% empty oil palm bunch), respectively water content values (7.99%; 7.89%; 7.09%; 7.09% ; 7.44%), density (0.32 g /cm3; 0.35 g/cm3; 0.33 g/cm3; 0.34 g/cm3; 0.39 g/cm3), ash content (1.60%; 2.17%; 2.11%; 2.70%; 4.12%), volatile matter (90.09%; 89.55%; 89.72%; 89.96%; 89.19%), bound carbon (8.23%; 8, 20%; 8.09%; 7.86%; 6.62%) and calorific value (4004.43 cal/g; 3961.25 calg; 3947.12 cal/g; 3867.85 cal/g; 3844, 75 cal/g).
