The aim of this reseach in to paint on silk fabric with batik technique using five natural dyes from neem tree bark lac mango leaves marigold and star gooseberry bark. The pre-mordant and after-mordant techniques were used in this work. There were 10 Mordants Aluminium Potassium Sulfate Copper Sulfate Sodium Dichromate Tannic Acid Tartaric Acid Tin (ll) Chloride and Calcium Acetate-Monohydrate were applied. The batik fabrics were characterized In color strength rubbing fastness washing fastness light fastness and stiffness. The result-indicated that silk Fabric painted with natural dye from neem tree bark could use all 10 mordants to improve color strength and gave various shade of color. The silk fabric painted with Natural dye from lac could not use all 10 mordants to improve color strength but it gave various shade. The silk fabric painted with natural dye from mango leaves marigold and star gooseberry bark showed that almost 10 mordants gave higher color strength and various shade. The mordanting technique would give good fastness and reduce the stiffness of batik fabric.

Research aims to bring the waste. The cashew nut shell the odor removal products. To reduce the use of chemicals. And reduce waste agricultural waste and Community Research finds that The cashew nut shell. When buming the charcoal. The moisture content is 5. 26 % with charcoal to absorb odors as well. The carbon shell of cashew nuts are finely ground can absorb it very well the pH of the solution averaged 8.17 ability to absorb the smell of charcoal bark seeds cashew nuts in a container that is stale take 3-5 days to product. Absorbs odors welL Vase Grapes on the product used the time to absorb the smell more than 5 days and less ability to absorb odors. The shell is made from cashew nut products odor removal is a method that can reduce the use of chemicals to eliminate any odor and reduce global warming and the other one.

This research is the analytical study of fibers from banana trees in northern area. The study has been conducted on planted banana-species areas in 5 northern provinces. There are 9 studied banana species. The objectives of the studies are to utilize these mentioned banana species for product creation. It is also to find out the banana-fiber-extraction process for new materials used as guidelines to design new products which help generate extra revenue for farmers after harvest season. The result from the research indicates that the most appropriate species for the research is Musa acuminata Colla due to its strongest texture in term of thickness. The leftovers of banana (stalk and pseudo stem in dried form) after agricultural process have been extracted into straight fiber ropes. Then they are processed into straight fiber ropes through hand-cutting by northern villagers. As for the 5 types of natural fibers. It is found that banana fibers mixed with hemp fibers at 50% proportion for each yields the highest pull force of 678.71 N. To sum up the manufacturing production and creation is in a good level by average value 4.17 and the product users’ satisfactions is a good level by average value 4.07.

The purposes of the research were to create and efficiency validation of computer assisted for the courses of practiced to cutting sheet metals based standard 90 / 90 and analyse the leaning achievement of the student after by using computer assisted instruction. The subjects in the study were 17 first year diploma students enrolled in Rajamangala University of Technology Phra Nakhon. The Researcher using the experiment by let the students do until test before class And then study by using computer assisted instruction focused on practiced to basic turning. After that let students do the unit test again at the class and calculate to find out the efficiency of the computer assisted instruction and analyse the leaning achievement of students after study. The research result revealed that the efficiency of the computer assisted Instruction was efficient in standard 90 /90. Moreover. after learning achievement At significant level of 0.05
