This research aims to develop the ceiling board mixed with coconut coir. The 5 ratios of gypsum plaster: coconut coir: sodium silicate: tap water are equal to 1 : 0 : 1: 0.03 1: 100: 1: 0.03 1: 150: 1: 0.03 1: 200: 1: 0.03 1: 250: 1: 0.03 และ 1: 300: 1: 0.03 by weight. The ceiling boards were produced by casting in normal temperature (30 – 35 degree of Celsius). The properties testing of ceiling board mixed with coconut coir followed the TIS 219-2009 standard (gypsum plasterboard) including: breaking load nail pull resistance deflection water absorption density and thermal conductivity coefficient. From the results 1 : 1 5 0 : 1: 0.03 is the most suitable ratio of ceiling board mixed with coconut coir. This developed ceiling boards can reduce the quantity of coconut coir waste and get the good thermal insulation ceiling board products

Clothes design for local Product Style Development Case study : Pha Chok Thai – Yuan Ratchaburi province there is important objective in the education studies the production of Pha Chok Thai – Yuan Ratchaburi province to style analyze Clothes Design for Local Product Style Development . The focus of the development of local products The study result meets that of Pha Chok Thai – Yuan Ratchaburi province there is format development of cloth design follows requirement way of consumer group by have the idea in cloth weaving original way cooperates the production for the business for responds to build market system where happens from the development follows idea frame in the community development cloth Thai weaving has whirled can separate weaving way 2 and encourage the idea development from garment of Pha Chok Thai – Yuan Ratchaburi province the point for example the point is first weaving for inheriting wisdom the point is second weaving for the business which bilateral the point can separate the character has of the fabric 4 the group for example 1 pha sin tin chok 2. pha sin Ta 3. the cloth no motif 4. the cloth of other designs will have weaving applied format character follows the idea of Weavers that create to go up from the experience by 4 both of group cloths have will the design that implies way idea lead original integrate with contemporary idea which can summarize get 2 the group for example 1. the original pattern 2. the applicability pattern. Study then lead the cloth in the group of sin ta comes to use in designing clothes because of the cloth in this group has design character that splits full the clothes there is the suitability in the bringing uses in designing clothes most and the design has small-sized and have using color various moreover the price still have the suitability in the bringing develops products format bring design the clothes for the age group works by age between 25 - 40 year by have analysis result attitude lead that have to build the filtration uses readymade clothes from the cloth weaves cloth natives comes to use cooperate designing clothes 6 group amounts emphasize format development are appropriate the target group and use valuable cloth is appropriate the bringing processes to garment clothes.
