The objectives of this research were 1) to study the design and experiment of materials for producing water hyacinth basketry templates from para rubber 2) to test the water hyacinth basketry templates from para rubber 3) to create a body of knowledge in the development of water hyacinth basketry templates. from rubber latex to the community The process of operation is to design the shape of a water hyacinth basketry to suit the use of the product first after that create a water hyacinth basketry template from para rubber by experimenting with a formula mixed with natural rubber latex and experiment with weaving vegetables. water hyacinths to find the best techniques and styles Results from research on the design of water hyacinth wicker templates from rubber latex and testing of water hyacinth wicker template designs from rubber latex. The aim is to invent materials to solve the problem of replacing the old wicker template. From the research it was found that the water hyacinth basketry model was made from rubber latex. There are two techniques for creating new templates: removable templates and removable templates. and non-removable templates Removable latex coated wicker template can produce many pieces easy to weave The wicker template part is coated with rubber latex. Non-removable or weave cover It can be used to weave as a furniture product with the properties that were discovered that it has a long service life. It is durable strong and durable. Flexibility to reduce shock during weaving. and can be a tool in the profession Can reduce the cost of producing water hyacinth handicrafts Model development part There is a design template for water hyacinth basketry which is a water hyacinth wicker product that has a shape that is exotic modern beautiful and useful according to the products unique characteristics and is a valuable work that can decorate the house beautifully.

Most of the current containers that we put food are made of plastic or foam boxes. After the use is finished the container becomes rubbish and will greatly affect the environment. Due to slow degradation Plus informal disposal And higher consumption The use of natural products is in great demand. Because it is beautiful and natural-looking pleasing to consumers Therefore the basic processes forming patterns were studied by rubber product molding techniques. Determine the material to be molded into the sample container. Design and build a small molding set. Provide binders used for the stabilization of natural materials. Experiment for forming and the Conclusion of the experiment From the results of operations and experiments it was found that the study of the prototype extrusion set Using a rubber molding technique Can be applied by various elements The process of rubber molding can be used in the development of natural container molding and the process can produce prototype containers from natural materials. Under the suitable size of the mold the area of the mold is smaller than the mold plate area of the machine or the size of the mold area the area of no more than 60-70% of the mold holder plate.

Metal casting with Green sand mold is essential for participation in the manufacturing industry that requires natural resources and chemicals as an element. This research studied the effects of the right mix of mangosteen shell powder on green sand mold. The objective is to study and analyze the mixture of moist sand formations consisting of natural sand bentonite mangosteen shell powder and water affecting the properties of green sand mold by experiment method. Starting from studying relevant information of natural materials that affect sand mold and planning experimental design by using the experimental design program for the trial version in the experimental design and analyze results. The results showed that mangosteen peel powder had an effect on the properties Compression strength and higher hardness of sand mold but does not increase the ability to release a lot of air permeability The optimum blend ratio was composed of 90% reused sand 7% bentonite 1% water and 2% mangosteen powder by weight air permeability. The hardness of the sand casting was 0.71 kg/cm2 47.36 and 94.06 Scale B respectively.

Molds manufacturing to produce chloroprene rubber product with carbon steel over time the mold surface will wear. From the original. The practice in the industry often uses surface coatings (Hard chrome method) or change materials to create molds. Therefore this research is to study the effect of corrosion or wear. To see the size of surface mold changed in the experiment. Based on a tolerance of 0.1 millimeters at the molding point and after molding in the actual work conditions of a 2-3 weeks sample and mold size measurement. At less than 10 times the permissible coordinate value is 0.01 millimeters. The experiment found that. The wear of carbon steel molds was formed with chloroprene rubber. It has a very small value when referenced to the tolerance coordinates which is not significantly reduced when the rubber specimen size is determined. The allowance range is 10 μm to 100 μm. Therefore the design of chloroprene rubber to make molds with carbon steel. It can help reduce production costs. Without replacing with corrosion-resistant materials or adding coatings.

The objective of this study 1) To study the shape of the template from the process of making basketry 2) To design a template hyacinth wicker products creative products 3) To test the woven pattern of water hyacinth wicker 4) To create a unique product that is more valuable to the local wisdom and value. Consumerism toward the development of water hyacinth wicker patterns. By specifying a sample group of 57 people. The tools used in the research consisted of the satisfaction questionnaire on the template pattern water hyacinth weave basketry to local creative concept product. The results of the design of the water hyacinth wicker pattern design to the product of local identity concept found that the design shape can be a shape that has a concept as a creative product. Form 1 wicker-shaped pattern template from water hyacinth leaves The product is a chair with an average of 4.58 Form 2 template oval shaped wicker basket shape. The product was a basket of legs with an average of 4.48 Form 3 basket shaped shape from the bowl shape the product received the basket has a value of 4.22. All 3 forms that can be developed in the form of products that can satisfy level most satisfactory shape is the molds for Basketry 1. The product is a chair that is beautiful the proportion of products is suitable for use and strong products are local and creative in the process of water hyacinth wicker requires a template for forming. The original material used to make the wicker template is plywood or foam material. During the study phase the researcher invented the material for making water hyacinth woven basket template using rubber water mixed with plastic watercolor foamed foam templates are used for easy handling and longer durability.
