Development of Planters from Residual Materials of Oil Crops into Community Products to Support Tourism in Pha Taem National Park Ubon Ratchathani Province Using a STEAM BCG Project-Based Learning

การพัฒนากระถางจากเศษวัสดุเหลือใช้จากพืชน้ำมันสู่ผลิตภัณฑ์ชุมชนเพื่อสนับสนุนการท่องเที่ยวในอุทยานแห่งชาติผาแต้ม จังหวัดอุบลราชธานี ด้วยโครงงานสะตีม บีซีจี

Abstract

         The objectives of this research are as follows: 1) To study the ratio of residual materials from oilseed plants and suitable binder materials for molding with a successful mold. 2) To study some physical properties of pots made from residual materials from oilseed plants. And 3) To study satisfaction with pots made from residual materials from oilseed plants. The study results show that the appropriate ratio for molding with a successful mold can be achieved in all 5 experimental sets. The study results of certain physical properties through strength testing indicate that all experimental sets are generally in good condition. Experimental set 5 exhibited the best water absorption and expansion properties, with values of 16.68 and 8.06 percent, respectively. And experimental set 4 exhibited the least heat absorption, with a value of 2.22 percent. When considering the overall picture, it was found that the ratio in experimental set 5, consisting of coconut husk: palm fiber: binder (3:3:4), is most suitable for use as plant pots. Due to its strength, optimal water absorption, and excellent expansion properties, this set exhibits the most suitable characteristics for the growth of plants. Additionally, it can be a cost-effective and environmentally friendly product as it has the least amount of binder material, making it a valuable material for community products. As per the study results, satisfaction with pots made from residual materials from oilseed plants is at the highest level.
