The objectives of this research were to determine the suitable times of pork slices drying using microwave followed by hot air and to find specific energy consumption during drying. The physical characteristic (color and hardness) and the sensory test of dried pork slices were also investigated. Pork slices with the sizes of 50x50x1.3 and 50x50x2.2 millimeters were dried using the microwave at the powers of 160 320 480 640 and 800 watts until the samples did not burn during drying. Then the samples were dried using hot air at a temperature of 110oC until the moistures of the samples were lower than 20% dry basis. Based on the experimental results it was found that the suitable times of the samples drying using microwave were 50-600 seconds which depended on the microwave powers and the pork thicknesses. In hot air drying period drying times of the samples with thicknesses of 1.3 and 2.2 millimeters were 30 and 45 minutes respectively. The microwave powers had no significant effect on the redness (a value) and yellowness (b value) of dried pork the hardness of dried pork and the specific energy consumption (P<0.05). The pork thicknesses had the significant effect on the lightness (L value) and yellowness (b value) of dried pork the hardness of dried pork and the specific energy consumption (P<0.05). Moreover sensory scores of the dried pork obtained from this research were close to those obtained from the local market.

The study and development to design mushroom nursery for installed within the orphanage cultural school (Main 67) Lao PDR. Is a research to promote and develop the production of raw materials for cooking in the school. Consequently the school has a policy to promote plants and raise animals to prepare food for students. But the amount of the produce is not enough to meet the demand for consumption of students. Therefore the researcher has the idea to design a mushroom nursery that is suitable for for installed within the school. Because the cultivation of mushrooms in the nursery is not difficult and still produces all year round. If there is promotion of mushroom cultivation in addition to plants and animals. Will make the school have raw materials that variety and enough for use in cooking for students. Which will result in students eating more complete categories. By the method of conducting the research beginning with the study and analysis of data to find the amount of mushroom cultivation suitable for the consumption needs of students. After that the study and development of the form of mushroom nursery that is suitable for the use and maintenance. Can be easily assembled and installed. Use materials that can be found locally and use a small budget. According to the research the mushroom nursery is a semiautomatic 3.27 x 8 meters consisting of modular system. By using bamboo and plastic mesh as the main material and inside using the method of placing suspended mushroom bags. Suitable for installation in most schools. Since it can be easily assembled and installed with materials that can be purchased locally. It is also easy to use and maintain. This nursey can produce approximately 2400 mushrooms or about 240 kilograms per month. In summary The study and development to design mushroom nursery for installed within the orphanage cultural school (Main 67) Lao PDR. It is the development of vacant spaces within the school to be agricultural areas that will benefit the school in many ways. Both the quantity of produce and nutrition budget and career promotion.

Nowadays increasing water pollution has put significant pressure on water resources. Natural organic matter and organic micro-pollutants have been found in potentially harmful concentrations in numerous water sources. Phthalate plasticizers are also micro-pollutants of concern; Di- (2-Ethylhexyl) phthalate (DEHP) is one of the most frequently observed plasticizers in the environment as well as one of the most persistent. The maximum permissible levels of these compounds in drinking water and wastewater discharged to the environment are set at low concentrations. In this research water samples were collected from the New Bang Kaen Canal in Bangkok Thailand (13°4906.1N 100°3042.4E) which receives wastewater from human activities and contains impurities in the water. Several common treatment technologies currently used to remove inorganic and organic contaminants from natural water supplies address serious environmental problems. Properly selected microfiltration membrane processes are elements of effective systems for water purification. Polymeric membranes are of primary interest for membrane separation techniques because they are both practical and effective. However pretreatment before using a microfiltration membrane is necessary for suspended solids reduction. This research used two types of polymeric membranes namely cellulose acetate membrane (CA) and polyvinylidene difluoride membrane (PVDF) and covers the most applicable requirements regarding pretreatment of the water intake. The performance of polymeric membranes for water treatment was also investigated. The water quality of the New Bang Kaen Canal was assessed in terms of turbidity SS and COD. This research has the potential to contribute to the monitoring of water quality in the New Bang Kaen Canal. Water quality monitoring is a fundamental tool for water resources management. The performance of polymeric microfiltration membranes was effective for water and wastewater purification in terms of solids organic substances and micro-pollutant i.e. DEHP compounds. Nevertheless the further development of polymeric membranes regarding fouling on the membrane surface and within pores needs to be improved to increase membrane performance and ameliorate the limitations of microfiltration polymeric membranes.

In the rubber situation The problem has accumulated. All sectors are mobilized. The idea is to solve the problem of falling rubber prices. Or the output overflow. Overpriced The rubber growers. Have been affected by the same. This is a problem that many sectors. Trying to find a way out Research or development Products that can be used to produce rubber. It is another way to alleviate the suffering of farmers. The characteristics of rubber processing. There are many types of rubber raw rubber rubber and rubber. And have specific properties in themselves. The obvious is flexibility. Rubber quality in each production source is not equal. It is a problem of creating products with many components of rubber. But many of the products do not require the quality of the rubber. The problem is less. Such as shockproof materials in various packaging. Especially the material inside the packaging. For glass and ceramic products Only flexible features are needed. The rubber coating on the material has been invented many experiments. Be it on wood on fabric etc. as well as paper. But rubber coating on paper. To use for such purposes. It is made to be shockproof material by means of the pump in the packaging. There is no such trial. Researchers have the idea to study and develop the process. Cushioning material from rubber coated paper. To be suitable for packaging applications for glass and ceramic products. With regard to the ability to actually use. Value for money. Industrial production The satisfaction of the consumer. And the standard of packaging. The researcher found that. Applying the varnish on three variables and mixing the three compounds results that if the coating is applied on a material with a resilient property it will increase the elastic properties of the material. Corrugated paper is particularly suitable because the rubber can be inserted into the corrugated paper inside the corrugated paper. The test results are very good. Satisfaction I found that the content provider is very satisfied with the format and usage. But in weight it is also a problem because of the water that makes the weight of the packaging. The researcher should consider that the weight of rubber latex should be improved.
