Members of Pineapple Leaf Group have gathered to produce paper from pineapple leaves left from pineapple harvest. The obtained paper has been used to make various types of products such as picture frames paper bags envelopes flowers key chains and so on for selling to visitors at tourist destinations and to those who came to observe the group’s production of paper and other local goods. However it is found that the product is not of much interest for the tourists as it should be. For this reason the researcher considers seeking appropriate solution to the group by using the pineapple leaves to make bas-reliefs with an aim to add value to pineapple leaf paper. From the creation of mold made of plaster and that made of resin and use both molds to make bas-reliefs it is found that the bas-reliefs obtained from resin mold are more beautiful and easier to produce. This is because resin mold is more durable clearer and lighter. The researcher has presented the bas-reliefs to 448 tourists who have come to visit the project during the period of one year and asked for their opinions and satisfactions. The results are that most of the respondents (327 persons) are female which accounts for 72.99% of all. Most of them or 352 persons (78.57%) obtain the secondary school diploma. The age range of most of the respondents (154 persons) is 31-40 years amounting to 34.38%. As for satisfactions of the quality of bas-reliefs made from pineapple leaves most of the respondents (72%) expressed “strongly agreed”. 75% of the respondents are “strongly agreed” with the product beauty. In terms of durability most of the respondents (61%) are “strongly agreed”. Concerning appropriateness of the product as souvenir most of the respondents (77%) expressed “strongly agreed”. Finally 73% of the respondents are “strongly agreed” with the idea that the product is potential for sale.

Bottle of poly propylene (Polypropylene: PP) to replace conventional non-conventional polycarbonate bottles. (Polycarbonate) are used as bottles and water bottles toys household goods which are BPA-contaminated and poly ethylene Terephthalic acid (Polyethylene. Terephthalate) PET water bottles juice bottles. Bottles And bottles and other drugs and chemicals have been canceled. Then turning to the bottle to PP because of the lightweight bottles float on water. Plastic and white The plastic safety can be reused many times (even used) in the UK has the plastic water bottles poly propylene and (Polypropylene: PP) to make water bottles so long but not as popular as bottle caps. open it (lid torn) bottle shape is beautiful with a little input. The process is a extrusion blow but from research using the dryer Injection blow (Stretch Blow) has studied the creation of injection molded preform 19 gram in order to blow a 500 ML size thickness. Preformed from 3.34 mm to 3.46 mm the average measured height of the preform from a mean of 70 mm measured at 69.88 m. m. the oldest of the preform. the average measured 25 mm and 24.96 mm is how a 500 ML size bottle blow molding blow molds percent discrepancy between the form specified. Average Percentage 0.0853 experimental results Blow the preform 19 gram of the injection can be molded into the bottle completely and can not be used as drinking water is due to the equipment used. blown trial Need to study next.

The purpose of this research is to study the effect of a safety system provided for wall tile external building activity on productivity. The safety system composed of (1) stable scaffolding system (2) providing clean and not slip walkways on the scaffold (3) installation of handrails not less than 0.90 meters in height along sides of the scaffold (4) installing safety nets around outside perimeters of the scaffolding (5) indicating working area (6) installing stairs (7) providing protection for people who works below (8) providing tools and equipments for transporting material which are safe and ready for using and (9) providing personal protective equipment for workers. Cost of the safety system is 79318 baht for a wall tile area of 385 m2 or approximately 206 baht/m2. Productivity rates for prior and after the used of safety system are 1.91 and 1.85 m2/person/day respectively. The productivity declines for approximately 3 %. In addition our study found an impact of work is a height of Building the wall tile external productivity could decrease for 6 %.
