Abstract

Pengolahan limbah sebetan dari penggergajian kayu kelapa dengan sistim  penyambungan dan penggabungan atau laminasi. Kayu sebetan yang telah dikeringkan dibuat strip dengan ukuran 1 cm x 4 cm x 25 cm dibuat sambungan jari dan bangku dengan menggunakan perekat PVAc. Hasil penelitian menunjukkan bahwa  keteguhan tekan  dan keteguhan lentur paling tinggi pada perlakuan sambungan jari dengan berat labur 200 gr/cm2  yaitu  231,853 kg/cm2 dan 195,809 kg/cm2. Keteguhan tekan sambungan jari  dengan berat labur 175 gr/cm2 dan 200 gr/cm2 memenuhi syarat bahan baku bangunan struktural. Dan  nilai keteguhan lentur sambungan jari  dengan berat labur 175 gr/cm2 dan 200 gr/cm2 tidak memenuhi syarat untuk bahan bangunan struktural. Keteguhan tekan, keteguhan lentur dan delaminasi dipengaruhi dari bentuk sambungan dan berat labur. Bentuk sambungan jari  memiliki keteguhan tekan dan keteguhan lentur lebih tinggi dibanding bentuk sambungan bangku.

Abstract

Non-timber forest products (NTFPs) such as the root of Akar Wangi (Vetiveria zizainoides), Durian’s bark (Durio zibethinus Murr), Jaringau (Acorus Calamus L.), Liligundi (Vitex trifolia), Gemor bark (Alseodaphne spp.),  and Neem seeds (Azadirachta indica A. Juss.) have good potential as a natural insecticide. They can be used  for anti-mosquito materials that can be prevent the development of vector-borne Dengue Haemorrhagic Fever (DHF). Disruptive effects of the plants to the insects come from the odor which produces from the plant. Judging from the compounds that contained in non-timber forest products (NTFPs), beside used as anti-mosquito repellent, it can also used  as other pests repellant such as bugs,   termites, ants, etc. The end product also can be diversed  as insect repellent burns, topical / lotion, spray, and others.Keywords :  akar wangi,  durian bark, jariangau, liligundi, gemor bark, mimba, natural insecticide

Abstract

Aren (Arenga pinnata) is one of the plants that can be utilize as the raw material for bioetanol. The research of bioetanol producing used nira aren as raw material has been conducted by yeast of pure culture Saccharomyces cerevisiae and fermipan. The process is done by fermentation and distillation based on the duration of fermentation, concentration ratio of starter to the substrate by each type of yeast used. The result of research shows that the highest yield of bioetanol on pure culture fermentation as long 50 hours with 10 % concentration of starter, that is 14,9 %. The highest content of bioetanol is on  fermentation as long 75 hours with 5 % concentration of starter, that is 73,0 %. Fermentation with fermipan, the the highest yield and concentration of bioetanol  is at the fermentation as long 75 hours with the starter concentration of 15 %, that is                  10,1 % and 66,0 %.Keywords:  nira aren, saccharomyces cerevisiae, fermipan, starter concentration, output concentration of bioetanol

Abstract

The wood stock nowdays is limited, so it is needed the effect to develop the making of boat wood using lesser known wood. In addressing the limited number of wood supply include wood from forest plantations as well as the people that potential is quite large for a variety of purposes. This research aims to make the process less wood preservation is known as the substitution of raw materials manufacture of traditional boats which of wood is jengkol (Pithecellobium jiringa Benth IC Nielsen), kupang (Ormosia sumatrana Prain), tarap (Artocarpus adoratissimus) and Acid (Mangifera applanata Kosterm). The utilization supported by the preservation process, using permethrin, parachem and impralit CKB. Concentration are used 5%, 10% and 15% by length of immersion respectively 10 days and 15 days. The results of the study showed that retention was likely to increase up to a concentration of 10%. The best retention was in kupang wood using 10% concentration parachem by 10 days immersion. Based on the research results of the four types of wood preserved with preservative resistant to all three compounds in marine wood borers.Keywords:  wood of jengkol, kupang, tarap and acid, preservation, traditional boat

Abstract

Utilization of rattan waste and gemor bark (Alseodaphne spp) distillation  for particle board had been carried out. The aim of this research was to know physical mechanical particle board from rattan waste mixed with gemor bark distillation. The raw materials used were cut-rattan waste of 2 cm and gemor bark distillation mashed in 16 mesh. The adhesive used were starch and PVAC. Composition variety of the mixture of rattan waste and gemor bark distillation particle were 50%: 50%, 60%: 40%, 70%: 30% and 5% adhesive. The results showed that highest average of modulus of rupture (26,62 kg/cm2) was obtained in 60% : 40% comparison of rattan waste and gemor bark distillation with starch adhesive (a2b1) and the density was 0.75 gr/cm3. The highest average of modulus of elasticity (633,76 kg/cm2) was in composition of 60%: 40% with PVAc adhesive (a2b2) and the density was 0,71 gr/cm3. The highest average of tensile strength (3,15 kg/cm2) was obtained in composition of 60%: 40% with starch adhesive (a2b1) and the density was  0.75 gr/cm3.Keywords: rattan waste, gemor bark distillation, particle board
