Based on the research on creation of bas-relief molds for production of bas-reliefs made from boiled pineapple leafs conducted by Rachadasak Pengcum of which purpose was to help generate income for members of Pineapple Leaf Paper Community Enterprise Ban Pasang Wiwat Mueang District Chiang Rai Province it was found that the bas-reliefs need further improvements in terms of appearance and durability as well as the use of other natural raw materials to produce them. The researcher therefore has considered developing the previous research by applying other 3 valueless natural materials which include rice straw water hyacinth and banana stem skin to make bas-reliefs for different beautiful surfaces of the products. Also the quality of bas-reliefs has been comparatively investigated by surveying satisfactions of members of the Community Enterprise and visitors to the project towards the bas-reliefs made from rice straw water hyacinth and banana stem skin. The total period of questionnaire distribution was 3 months. There are 59 respondents administering the questionnaires most of whom (43 persons) are female which accounts for 72.88 per cent. The majority of the respondents (25 persons) obtained junior/senior secondary school diplomas or equivalent accounting for 42.37 per cent. 16 respondents or 27.12 percent are 60 years of age. As for satisfactions towards the bas-reliefs made from rice straw 89 times of “strongly agree” was selected whereas 126 times of “pretty much agree” 75 times of “fairly agree” and 5 times of “disagree” were marked by the respondents. Concerning the bas-reliefs made from water hyacinth 87 times of “strongly agree” was selected while 97 times of “pretty much agree” 110 times of “fairly agree” and 1 time of “disagree” were chosen. When asked about the bas-reliefs made from banana stem skin the respondents selected 77 times of “strongly agree” 99 times of “pretty much agree” 110 times of “fairly agree” and 8 times of “disagree”.

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.
