The objective of this qualitative study was to develop and determine security measures for private organizations. Documentary analysis and focus group technique were used as a method for gathering data. Eight participants who had experiences in security management were participated in a focus group. Data from two sources were gathered and integrated for data analysis. The results of data analysis led to the development of security measures factors. Findings indicated that there were five factors of security measures that needed to be implemented and carried out in private organizations including building awareness of technology development in security; integration of architectural security components; developing security systems; human resource management which encompasses security personnel and sharing knowledge; and determining appropriate security procedures that relate to nature and physical of organizations.

The development of ethanol fermentation of jackfruit wastes by a medium size distillation machine aimed to study and develop an ethanol fermentation method that gives optimal production of ethanol. In this research the ethanol production capability of 4 different groups of microorganisms including natural microbes microorganisms in stock rice fermented Saccharomyces cerevisiae EDV 492 and S. cerevisiae EC 118 is compared. The following procedure was implemented to allow the prescribed comparison: 1) microbes culturing (350 ml) for a total period of 20 days. Based on the study results all four groups of microorganism were capable of growing in the given culture medium which is sugar substrate. 2) Small sized fermentation (1 liter) for a total period of 4 days. From this second procedure it can be discovered that microorganism in stock rice fermented and S. cerevisiae EC 118 were highly efficient in producing sugar and ethanol 14% and 13% (v/v) respectively. 3) Develop small sized fermentation to a medium sized fermentation (20 liters) by fermenting natural microbes for a total period of 4 weeks until sugar is obtained. According to the study glucose must be added to increase the sugar level up to 25% Brix in order to provide sufficient substrate to allow ethanol production of the studied microorganisms. During ethanol fermentation process it can be found that microorganisms in stock rice fermented and S. cerevisiae EC 118 produced the highest amount of ethanol at 16% (v/v) within the period of 10 days and 8 days respectively. Hence according to this development of ethanol fermentation S. cerevisiae EC 118 is the most efficient microorganism in terms of ethanol fermentation of jackfruit wastes. In addition after the distillation of 99% ethanol it can also be found that both microorganisms in stock rice fermented and S. cerevisiae EC 118 produced 720 ml and 740 ml of ethanol respectively.

Hydrogen sulfide (H25 cheap materials activated carbon scraped iron sand cement and rice husks applied to the small scale biogas production at 30 ppm within 6 hours. The filter materials with highest to lowest H48.18 percent respectively. In the medium scale biogas production (20 L) at 30 ppm. Scraped iron and sand mixed with activated carbon filter had the best H(200 L) production of the biogas fermentation (30 ppm biogas product) sand mixed with activated carbon filter at the ratio 60:40 displayed the best performances in removing H2(3 day). It is the most environmental friendliness as well as cost-effective filter for biogas fermentation at scale up sizes at least 20 L. S) is found to be one major serious contaminant to biogas production system. In this research the team aimed to develop a high efficient filter for removing H2S from the biogas reaction. From all 2S absorptivity were activated carbon sand scraped iron and rice husks those accounted for 88.02 76.06 55 50 and 2S absorptivity (100 percent) and sand showed its H2S removal efficiency lower at 65 percent respectively. In larger scale S after incubated for 4.5 hours while scraped iron filter as well as activated carbon filter functioned in H2S removal longer time (2 and 3 days respectively). In order to be able to practically apply for continuous filtering H2S from the continuous biogas production sand mixed with activated carbon filter exhibited long last filtration

Natural compost or organic fertilizers suitably applied to soil since it improves soil quality is cheap and easy to manage and has no pollution residues. However the right ratio of ingredienttypes as well as enough fermentation period have to be tested in order to obtain suitable fertilizer for each particular plant species. In this study researchers have conducted experimental fermentation of organic composts composed of various ratios of either residues of bagasse or banana pulp mixed with sludge. This organic compost performs as organic fertilizer adding nutrients to the sludge since the sewage sludge by itself can only help improve soil structure but has insufficient nutrients for the growth of plants. The sludge in the experiment was obtained from sewage sludge at WatSuanKaew Nonthaburi province. The results of the organic compost after fermented 49 days showed that the compost turned to brown and black and most plant materials were already macerated. The compost of sewage sludge mixed with banana pulp in the ratio of both 0.75 to 5.0 and 1.0 9 to 5.0 yielded the best growth of the morning glory. Both formulas accelerated the growth of seedlings of the plant to a high average of 15.0 ± 0.3 cm after grown for14 days. The concentration of main nutrients was also close to the values specified by the standard compost. This banana pulp compost with pH 7-9 helpedreduce the acidity in the soil. While organic fertilizer derived from sewage sludge mixed with bagasse could only help accelerate the growth of the seedlings but did not accelerate the proliferation of immature plants. Additionally the ratios of carbon to nitrogen in all bagasse composting samples were more inflated whereas the nitrogen phosphorus and potassium were under the specified standard. This bagasse caused lower pH to 5.0-6.0 contributing more acidic to soil. From all results of these findings the organic compost from the fermentation of banana leafs was therefore appropriated for improving soil quality by mixing with sludge. The organic compost provided enough major and minor nutrients that stimulated the plant growth as well. However the formulated ratio of the bananas leafs and sludge mixtures needed to be prior experimentally tested.

This research project has developed and produced natural fiber-reinforced cement tiles by incorporating natural fibers from para rubber leaves and torpedo grass and mixing them with cement and then compressed into a mold with dimensions of cube was 5 cm x 5 cm x 5 cm. The ratio of fiber and cement were 1:9 2:8 and 3:7 respectively. This study used both types of natural fibers including para rubber leaves and torpedo grass. This research found that torpedo grass mixed with cement in a ratio of 1:9 provided high quality of reinforced cement. The density of this sample was found 2.07 g/cm3. Moreover the dry shrinkage value and water absorption were 0.02% 0.10% respectively. The compressive strength was 64.25 kN or 0.23 MPa. In comparison with the standards of non-load bearing concrete blocks according to TIS 58-2530 the result shown that some experimental data are lower than criteria standard. Furthermore the adhesives (i.e. silica) are very important for the quality of natural fiber-reinforced cement
