Panicum repens is a species of grass. The paper has been made from non-wood materials for long times. This research was used Panicum repens for made grass pulp as non-wood fiber. The influence of alkaline concentrations on properties of pulp from Panicum repens was investigated under room temperature. Alkaline concentration levels were varied at 0% 5% 10% 15% and 20% respectively. Moreover Paper pulp from Panicum repens was observed by scanning electron microscope (SEM). This research has controlled the length of fiber approximately 0.5- 2.5 cm before soaked with alkaline concentration at 1 hour and soak with water for controlled pH value at 7-8. Paper pulp was formed on a sieve. The result showed that color of paper pulp made from Panicum repens was light brown and green. SEM showed that alkaline concentration affects the physical properties of paper pulp. Moreover true density of paper pulp was also investigated in this research.

This research is a study on the Development of Paper and Packaging from Rice Husk and Rice Processing Wastes for producing for Thai Art Conservation. This research purpose to develop products and packaging from the rice husk in rice processing to study the processes of paper production and forming products to design and develop products and packaging and to transfer technology products and packaging from the leftovers in rice processing to conserve Thai arts to the community and to study the satisfaction of the product and packaging development program from the leftovers in rice processing in order to conserve Thai arts to the community. The research findings can be summarized as follows: 1. In this research the research team produced paper and molded products experimenting with the ratio of RICE HUSK and paper SA fibers and find the best ratio of rice husk 50: paper SA fibers 50 so that rice husk can better adhere to paper and creates a beautiful texture for making products. Moreover this research uses the waste from the rice processing process it able to develop products according to objectives. At the same time can be produced at the household level. As well as finding marketing methods for new products to be able to sell which generates income for the community. 2. The results of the physical characteristics of paper produced from rice husk paper with the ratio of rice husk 50 to 50 has a moderate weight. The paper can be folded. The tensile strength of the paper is moderate. The surface is good. The characteristics of the paper after coated with waterproofing it was coated with natural extracts and environmentally friendly. When testing the water color paint on paper the water color slowly absorbed but does not spread along the paper fibers and also slightly absorbed in the backside paper. 3. In this research the development of products and packaging from the leftovers in rice processing for preserving Thai art into 2 categories 1. Develop paper from rice husk for processing into products and developing molded products from rice husk consisting of 3 sets of ornaments consisting of necklaces bracelets earrings 4 sets of home decor consisting of pans wall paintings and 3 sets of household items consisting of 4 multipurpose boxes fruit trays altar table 4. The knowledge transfer by organizing a workshop for theoretical and practical work the duration of knowledge transfer was 2 days 50 participants between 11 - 12 august 2019 at Bang Tachong Community Enterprise Village No.8 Tha Ngam Subdistrict and District in Buri Sing Buri province. Most participants are satisfied with the highest levels in all questions.

This research aimed to develop paper from oil palm empty fruit bunch (Fb) oil palm mesocarp (M) and paper mulberry (P) with chitosan coating to be used as single-use paper bag for dry food products. The optimal pulp preparation conditions for Fb M and P fibers were boiling in 25 25 and 15% NaOH solution at 170 170 and 100°C for 3 hours respectively. The optimal H2O2 concentrations for bleaching of Fb M and P pulps were 40% 40% and 0.2% respectively. The obtained pulps were used to prepare papers with the basis weight of 109 g/m2 . The papers consisted of Fb M and P pulps at ratios of 70:0:30 (FbP) 0:70:30 (MP) and 35:35:30 (FbMP). It was found that FbP paper showed superior physical and/or mechanical characteristics than those of MP and FbMP. FbP papers were then coated with chitosan solutions (0.2-0.6%) to further improve their mechanical properties and reduce their water absorption characteristics. The optimal concentration of chitosan was 0.4%. This study showed that all three types of pulps could be used to produce papers that had equal or superior mechanical- and water adsorption properties as compared to those of commercially available paper bags made from wood pulp.

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.
