นวัตกรรมเถ้าแกลบ-เปลือกไม้ในคอนกรีตมวลเบาที่เป็นมิตรกับสิ่งแวดล้อม
This research presents a study of the compressive strength tensile strength flexural strength and water absorption of Cellular Lightweight Concrete containing fine rice hush-bark ash. Portland cement (CT) is partially replaced with pozzolans 20 30 and 40% by weight of the cementitious materials. The results show that the compressive strength tensile strength flexural strength and low water absorption of Cellular Lightweight Concrete improves substantially with partial replacement of Portland cement with rice hush-bark ash. Cellular Lightweight Concrete mix cement containing 20 and 30% of pozzolans can be used to make cementitious materials
การวิจัยด้านคอนกรีตพรุนที่เป็นมิตรกับสิ่งแวดล้อม
This research presents a study of the compressive strength flexural strength coefficient of permeability and superplasticizer requriment of Porous Concrete containing fine fly. Portland cement (CT) is partially replaced with pozzolans 0 20 30 and 40% by weight of the cementitious materials. The results show that the high compressive strength flexural strength and low total void ratio of Porous Concrete improves substantially with partial replacement of Portland cement with fly ash. Porous Concrete mix cement containing 20 and 30% of fly ash can be used to make cementitious materials. In addition the use of fly ash produces Porous Concrete mix with good compressive strength flexural strength total void ratio and coefficient of permeability.
เครื่องผลิตตะเกียบไม้ไผ่ด้วยระบบควบคุมอัตโนมัติ
This research presents a bamboo chopsticks machine with automatic control system. The production of bamboo chopsticks the current will be cut to get the machine to enter the bamboo chopsticks using the machine. The machine will hammer bamboo rotation of the electric motor. The AC motors with high power. Currently the production of chopsticks mostly small businesses. Lower costs which resulted in lack of effective security. This research presents the design and techniques with bamboo chopsticks production automation. The objective is to make the production of bamboo chopsticks are secure and compliant. To increase productivity and reduce the danger of the machine. In designing the Arduino technology is used in the development of electronic prototypes designed to be user for both hardware and software advanced application control equipment used in the production of chopsticks for safe to use on the incidence of danger from the use.
การพัฒนาชุดฝึกทักษะงานมาคราเม่ เรื่องที่แขวนกระถางต้นไม้สำหรับนักเรียนที่มีความบกพร่องทางการเรียนรู้กรณีศึกษาวิทยาลัยอาชีวศึกษาเสาวภากรุงเทพมหานคร
The purpose of this thesis were: 1) to develop skills practice sets with a Macramé plant hanger for students with learning disabilities. 2) to examine the effect of using a Macramé skills practice Kits to make the Macramé plant hanger for students with learning disabilities. The sample group were 3 students with learning disabilities in home economics department Saowabha Vocational College. The instruments used in this research were student behavior observation forms Expert interview and Macramé skills evaluation forms. The findings revealed that: 1) Practice sets for Macramé work with Macramé plant hanger for students with learning disabilities had 2 sets with 8-10 patterns. Which skill training set A consists of Macramé methods handouts and the skill training set B consists of Macramé methods video. 2) The results of the study were the 1st student can be used the both sets. Which they were finished their works in time and had a good quality Macramé work pieces. And the 2nd and 3rd students can be used the skill training set B to be made work pieces with correct pattern more than the skill training set A set.

The objective of this research was to compare the quality of Kanomchan which replace rice flour with Homnil rice flour Riceberry rice flour and Sangyod rice flour and to study the quantity of modified starches used in frozen Kanomchan products. Sensory evaluation of 30 panelists using 9 points Hedonic Scale. It was found that the panelist preferred Kanomchan that was made from Sangyod rice rather than the Kanomchan made from Riceberry rice flour and Homnil rice flour (p≤0.05). In the recipe of Kanomchan consist of 40.98% coconut milk 37.30% flour 10.65% cassava starch 9.02% cassava starch and 2.05% rice flour. Then using Sangyod rice flour in Kanomchan products to study modified starches suitable quantity for frozen Kanomchan products by three standards. Constitute 1% 3% and 4% by replacing of cassava starch. And compared with base recipe that not add modified starches. Then Kanomchan was freeze at -18 °c for three days. Before defrost with microwave and heated with 640 watts of microwave power for 2 minutes. The result found that frozen Kanomchan product which adding 3% modified starch had the most sensory points in every attributes. Except taste score texture (toughness) and overall score more than non-modified starches recipe (p>0.05). Then study three types of hydrocolloids. (guar gum gum Arabic and carrageenan) for develop quality of frozen kanomchan products by add hydrocolloids 0.1% for amount starches in frozen kanomchan products that using. Then freeze at -18 °c and reheat with microwave which had 640 watts of microwave power for 2 minutes. The result is guar gum had the most of linking points good texture that suitable with frozen Kanomchan products than caragenan and gum arabic. Results of the selection of the pattern of Kanomchan in packaging. By all experts choose a rose mold. and the packaging style numbrr 1 with the accompanying reasons name and the product brand prominently easy to remember beautiful colors look appetizing and linked the Thai dessert.
