Bamboo sawdust from chopstick production process was used as substrate for Indian oyster (Phoenix mushroom) cultivation. Experimental studies in cultivation material including wood sawdust bamboo sawdust and fermented chopped straw for 4 experiments - first experiment used 100 % of wood sawdust the second experiment used 25 % of bamboo sawdust mixed with 75 % of fermented chopped straw the third one used 50 % of bamboo sawdust mixed with 50 % of fermented chopped straw the forth one used 75 % of bamboo sawdust mixed with 25 % of fermented chopped straw and the last one used 100 % of bamboo sawdust. All experiments were analyzed for chemical properties nutrients in substrates for mushroom growing and yield of mushroom. The results showed that each type of mushroom substrate with different humidity. pH is suitable for use as a mushroom cultivation material. For quantity of nutrients in bamboo sawdust is more than wood sawdust. Increasing of nutrients is depending on increase fermented chopped straw. For mycelia growth in wood sawdust were faster than a bamboo sawdust culture. Yield of Indian oyster (Phoenix mushroom) found in any treatments. Especially in experiment 3 (50 % of bamboo sawdust mixed with 50 % of fermented chopped straw) is more suitable for Indian oyster (Phoenix mushroom) cultivation which compared to the other treatments because of highest yield mushrooms (175.11 grams per piece).

The purposes of this study were: 1) to develop the model of a participatory learning process for conserving the forest-resources of communities around Doi-Khun-Tan National Park 2) to compare knowledge attitudes and behaviors of the samples’ in conserving the forest resources and 3) to study the satisfaction of participatory learning process. The sample selected by a purposive sampling consisted of 48 subjects representing the communities around the area of Doi Khun Tan. The instruments included all these: 1) an interview 2) a participatory learning process program for conserving the forest-resources the area of Doi Khun Tan National Park 3) a questionnaire about the knowledge attitude and behavior of conserving forest resources and 4) a questionnaire about their satisfaction with the program. The data elicitation was drawn from three sources: 1) interviews and brainstorming 2) the assessment of the knowledge attitudes behaviors by the questionnaire and 3) the assessment of the satisfaction with the participatory learning process by the questionnaire. The study revealed these findings: 1) the participatory learning process of model fell into 6 steps consisting of a) the analysis of communities key informants and literature reviews b) the implementation of the knowledge to conserve the forest resources c) the implementation of the attitude towards conserving the forest resources d) the implementation of the behaviors of conserving the forest resources e) the assessment of the participatory learning process and f) the evaluation of satisfaction with the program; 2) the subjects’ knowledge attitudes and behaviors regarding forest conservation at the boundary of Doi Khun Tan before and after the participatory learning process are statistically different at the significance level of .05; and 3) the level of their satisfaction with the participatory learning process was high.

This research aims to study the application of cassava fiber. The fibers are taken from cassava and pineapple Head that 3 ratios are used to all of fiber mixing. The fiberboard production use 130°C of temperature with 20 – 50 kg/sq.cm of compressive pressure with 10 minutes per piece of rate. Their fiberboards have 681 – 724 kg/cu.m of density and 7.1 – 7.6 % of moisture. Resulting the CF 05 ratio (cassava: urea is equal to 0.95:0.13) is suitable ratio which has good physical and mechanical properties.
