Characteristics of wood pellets rubber (Havea brasiliensis) is not productive from Danau Salak village, Banjar Regency. The purpose of this research to know the characteristics of wood pellets from unproductive rubber wood includes moisture content, caloric value, density, ash content, fly and carbon bound substances. Dry wood until water content of 12-10%, then crushed into powder with crusher machine. The powder in sifted 40 mesh was then taken into doubt and sprinkled with starch. The pellets were inserted a print device, pressed with a hot temperature of 125 º C for 30 minutes with a pressure of 164 kg/cm3. The result of water content of rubber pellets is not productive at 7.28%, while the ash content test is 1.60%, calorie value of 4141.52 cal/g, density value of 0.9 g/cm3, flying substance rate of 71.58% and carbon level is bound at 19.53%. According to SNI Standard, NFRI (Korea), DIN (Germany) and PFI (America) The value of water content shown meets all standards, heat value only meet SNI and NFRI standards (KOREA), for density values simply do not meet the standard DIN (Germany), for the flying substances meet SNI standard and for the value of bonded carbon Also Meet SNI standardsKarakteristik pelet kayu Karet (Havea brasiliensis) tidak produktif dari desa Danau Salak, Kabupaten Banjar. Tujuan dari penelitian ini untuk mengetahui karakteristik pelet kayu dari kayu karet tidak produktif meliputi kadar air, nilai kalor, kerapatan, kadar abu, zat terbang dan karbon terikat. Kayu keringkan hingga kadar air 12-10%, kemudian dihancurkan menjadi serbuk dengan mesin crusher. Serbuk di ayak 40 mesh kemudian ditmbang dan dicapurkan tepung kanji. Pelet dimasukkan alat cetak, dipres dengan suhu panas 125ºC selama 30 menit dengan tekanan 164 kg/cm3. Hasil uji kadar air pelet kayu karet tidak produktif sebesar 7,28%, sedangkan uji kadar abu sebesar 1,60%, Nilai kalori sebesar 4141,52 kal/g, nilai kerapatan sebesar 0,9 g/cm3, kadar zat terbang sebesar 71,58 % dan kadar karbon terikat sebesar 19,53 %. Berdasarkan standar SNI, NFRI (Korea), DIN (Jerman)dan PFI (Amerika) nilai kadar air yang ditunjukkan memenuhi semua standar, sedangkan kaar abu hanya memenuhi standar NFRI (Korea), untuk nilai kalor hanya memenuhi standar SNI dan NFRI (Korea), untuk nilai kerapatan hanya tidak memenuhi standar DIN (Jerman), untuk zat terbang memenuhi standar SNI dan untuk nilai Karbon terikat juga memenuhi standar SNI.

Waste from oil palm, namely empty fruit bunches, can be used as an alternative for the manufacture of particleboard for optimal processing. The purpose of this study was to analyze the mechanical properties of particleboard from a mixture of oil palm empty fruit bunches and coconut fiber which includes flexural strength (MoE), and fracture toughness (MoR) based on the Indonesian National Standard (SNI). The manufacture of this particle board uses 5 treatments with 3 replications. The treatment given is a mixture of coconut fiber with empty palm oil bunches. The mechanical properties of particle board from coconut fiber and waste Empty Palm Bunches (EPB) have value flexural firmness(Modulus of Elasticity or MoE) with the highest value in the treatment of 75% coconut fiber and 25% EPB, which is 2794.11 kgf/cm², while the lowest value in the treatment of 100% EPB is 410.08 kgf/cm². The value of fracture (Modulus of Rupture or MoR) was highest in the treatment of 75% coconut fiber with 25% EPB, namely 30.36 kgf/cm², while the lowest value in the treatment of 25% coconut fiber with 75% EPB was 3.61 kgf/cm². Both of these tests do not meet the standards of SNI 03-2105-2006 with a minimum MOE of 20400 kgf/cm² and a minimum MOR of 82 kgf/cm²Limbah dari tanaman kelapa sawit yaitu tandan kosong dapat dijadikan sebagai alternatif untuk pembuatan papan partikel agar pengolahannya lebih optimal. Tujuan dari penelitian ini ialah untuk menganalisis suatu sifat papan partikel dari bagian mekanikanya yaitu keteguhan lentur (MoE), dan keteguhan patah (MoR) berdasarkan Standar Nasional Indonesia (SNI) yang berasal dari campuran tandan kosong kelapa sawit dan sabut kelapa. Pembuatan papan partikel ini menggunakan 15 sampel yaitu dengan 3 kali ulangan dengan 5 perlakuan yang berbeda. Perlakuan yang diberikan ialah pencampuran antara sabut kelapa dengan tandan kosong kelapa sawit. Sifat mekanika papan partikel limbah Sabut Kelapa dan TKKS memiliki nilai keteguhan lentur (Modulus of Elastisity atau MoE) dengan nilai tertinggi pada perlakuan 75% sabut kelapa dengan 25% TKKS yaitu 2794,11 kgf/cm², sedangkan nilai terendah pada perlakuan 100% TKKS yaitu 410,08 kgf/cm². Nilai Keteguhan patah (Modulus of Rupture atau MoR) yang paling tinggi yaitu pada perlakuan 75% sabut kelapa dengan 25% TKKS yaitu 30,36 kgf/cm², sedangkan nilai terendah pada perlakuan 25% sabut kelapa dengan 75% TKKS yaitu 3,61 kgf/cm². Kedua pengujian ini belum dapat memenuhi standar SNI 03-2105-2006 dengan minimum MOE 20400 kgf/cm² dan minimum MOR 82 kgf/cm²

The study aimed to determine the rendement of charcoal and wood vinegar and to identify wood vinegar chemical compounds made from ironwood deliquent waste. The study was carried out by using charcoaling facilities at the charcoaling center in the village of Asam â€“ Asam. The charcoal and wood vinegar rendements Â were determined after ironwood delinquent waste was heated for 21 days with a temperature of approximately 400 - 600 ÂºC. The results showed that the rendement of the charcoal and wood vinegar were 14.02% and 0.05%, respectively. The research with wood vinegar characteristic before purification was pungent, however after purification, the results did not sting; color pH before purification was blackish-brown, however after purification it was pale brown yellow; the specific gravity before purification was 1.012 and after purification, it was 0.97; the pH before purification is 3.63 and after purification 3.41; and acid content before purification was 3.73% and after purification it was 3.66%. As a whole, the physics test of wood vinegar is categorized in Japan standard, however, the color only before purification is not standard. There are five chemical compounds identified in wood vinegar both before and after purification.
