Abstract

Development of the rattan furniture industry today is quite fast although the amount of raw materials are decreasing, especially in commersial rattan commodities such as Manau,  Irit, Taman, Sega, etc. Their price is quite expensive too five species of rattan were used as research materials. There are Manau (Calamus mettanensis Becc), Toho (Calamus sp), Galang (Daemonorops verticilaris Griff Mart), Hijau (Calamus sp) and simpurut (Calamus panajuga Becc). For finishing materials, clear glass melamine (ML 131 and NC 141) were used in this research with three different immersion timer for 24 hours, 36 hours and 48 hours long. An immersion method without using any finishing materials was done as control materials. Result show that the average of volume expansion of rattan speseis using NC 141 are 1,56-3,16% in Marau; 1,36-2,91%; in Toho; 2,01-3,05% in Galang; 2,12-3,20% in Hijau and 1,90-2,14 in Simpurut. In the other hand, the average of volume expansion of rattan species using melamin ML 131 are 1,27-2,58% in Marau; 1,46-2,51% in Toho; 2,30-3,23% in galang; 1,10-2,79% in Hijau and 1,45-2,55% in Simpurut. In control materials the average of expantion volume in 5 species rattans is 2,53-3,99%. From those results, the best method was shown in using NC 141 which can prevent the volume expansion and give great influence in volume expansion value.Keywords: rattan, finishing material, melamine ML 131, melamine NC 141, volume expantion.

Abstract

Penelitian mengenai pengaruh kadar perekat dan jenis bambu terhadap sifat fisis dan mekanis papan partikel telah dilakukan. Penelitian ini bertujuan untuk mengetahui sifat papan partikel dari bambu ditinjau dari aspek teknis/ proses pembuatannya, sifat fisis dan mekanis, pengaruh jenis perekat dan jenis bambu terhadap papan partikel yang dihasilkan. Jenis bambu yang digunakan adalah bambu apus (Gigantochloa apus Kurz), bambu kuning (Bambusa vulgaris Schrad), dan bambu manis (Gigantochloa atter Kurz). Adapun jenis perekat yang digunakan adalah Urea Formaldehid (UF) dan Polyvinil Acetat (PVAc) dengan kadar perekat masing-masing 8, 10 dan 12% dari berat kering partikel bambu. Hasil penelitian menunjukkan bahwa perekat Urea Formaldehid (UF) dengan kadar perekat 12% dari berat kering partikel menghasilkan papan partikel bambu yang paling baik untuk semua jenis bambu.

Abstract

Saw dust waste has a big potential to be used as charcoal briquettes. The galam wood charcoal was added to increase the quality of the Meranti saw dust charcoal. The composition arrangement of Meranti saw dust and galam wood charcoal were 100%:0% ; 90%:10% ; 85%:15% ; 80%:20% ; and 0%:100%. Tapioca flour was used as the adhesive agent. We use 10.000 kg/cm2 for the pressure clamp. The result show that the charcoal briquette have the physical characteristics such as 3.78% - 4.54% for water content with the density between 0.49 – 0.77 gr/cm3 – 0,77 gr/cm3. For the chemical characteristics, the ash content is between 2.64% - 3.24%, substances fly content is 25,40% - 29,40% and the calorific value is between 5502.40 – 6249 cal/gr. The addition of galam wood charcoal is causing the decreasing of the ash and substance fly content but in contrast the calorific value and the residual carbon are increase.Keywords: charcoal briquette, meranti, galam, physic, chemistry

Abstract

The research about the utilization of gemor stem skin oil (Alseodaphne spp) as an alternative natural repellent mat has been done. This research aim to obtain essential oils from the bark  using distillation and extraction method and used  as repellent active ingredient. The result showed  that the product is  efficient and biodegradable  proven by a test activity against the mosquito (Aedes aegypti). Varying the concentrations used are 10%, 20%, and 30% with the time observations to 02, 04, 06 and 08 hours after treatment. The results showed that anti-mosquito activity tends to increase with higer concentration. The use of 30% doses of Gemor bark  essential oil is  effective. The Effectiveness of the product against the mosquito (Aedes aegypti) and the economid value were compared with the innovator product containing DEET (N, N-diethyl-m-toluamid). Keywords: alseodaphne spp, repellent, concentration, Aedes aegypti, essential oils.

Abstract

Sejak lima tahun terakhir Indonesia mengalami penurunan produksi minyak nasional akibat menurunnya secara alamiah cadangan minyak pada sumur-sumur produksi. Untuk mengantisipasi hal tersebut salah satunya dengan cara memanfaatkan biomassa kayu sebagai sumber energi terbarukan. Sumber energi biomassa mempunyai beberapa kelebihan antara lain merupakan sumber energi yang dapat diperbaharui (renewable) sehingga dapat menyediakan sumber energi secara berkesinambungan (suistainable). Sebagai bahan bakar, biomassa perlu dilakukan pengolahan terlebih dahulu agar dapat lebih mudah dipergunakan yang dikenal sebagai konversi biomassa. Teknologi konversi biomassa tentu saja membutuhkan perbedaan pada alat yang digunakan untuk mengkonversi biomassa dan menghasilkan perbedaan bahan bakar. Beberapa teknologi  konversi biomassa yang bisa diterapkan antara lain :biobriket, gasifikasi, pirolisa, liquifikation, biokimia dan karbonisasi. Metode yang paling baik untuk menghasilkan biomassa kayu adalah teknologi konversi gasifikasi.
