Abstract: This research aims to analyze factors affecting the job performance of village agricultural volunteers (VAVs) in Sukhothai Province and to explore the challenges and recommendations for VAV operations in this province. A structured interview was conducted with 275 VAVs. Data were analyzed by descriptive statistics, including frequency, percentage, maximum and minimum, mean, and standard deviations. Multiple regression analysis was employed to identify factors influencing VAVs' job performance.
The study found that VAVs had an average age of 48.85 years, with approximately 45.5% having completed high school education. They had an average of 20.47 years of agricultural experience, cultivated an average of 28.09 rai of land, and had an average household income of 240,732.63 baht per year. Furthermore, nearly 96% of VAVs received support from government agencies, and 99.6% utilized online social media for agricultural-related knowledge.
Regarding agricultural knowledge, VAVs demonstrated a high level of knowledge (x ̅= 4.22) and exhibited a high level of job performance in fulfilling their roles and responsibilities. Based on an analysis of factors influencing VAVs' job performance, it was found that training positively influenced their job performance at a 0.001 significance level. While sources of agricultural information and knowledge, and support from government agencies positively impacted job performance at a 0.05 significance level.
It is recommended that the public sector and relevant public agencies should pay attention to sources of agriculture-related information, focusing on their varieties, easy access, and convenience of use. Such sources would enhance VAVs access to broader agricultural knowledge. The relevant public agencies should also emphasize knowledge provision to VAVs to operate more effectively, such as VAV-centered training programs and learning forums. In addition, they should provide the necessary tools and knowledge required for VAV operations. Policy initiatives related to compensation and legal status for VAVs should also be considered.2023-08-01T00:00:00Zปัจจัยที่ส่งผลต่อการเข้าร่วมกลุ่มวิสาหกิจชุมชนแปลงใหญ่สตรอว์เบอร์รีของเกษตรกรในตำบลบ่อแก้ว อำเภอสะเมิง จังหวัดเชียงใหม่ศรัณย์ โสมขันเงินhttp://cmuir.cmu.ac.th/jspui/handle/6653943832/790712023-10-17T01:04:35Z2566-08-01T00:00:00ZTitle: ปัจจัยที่ส่งผลต่อการเข้าร่วมกลุ่มวิสาหกิจชุมชนแปลงใหญ่สตรอว์เบอร์รีของเกษตรกรในตำบลบ่อแก้ว อำเภอสะเมิง จังหวัดเชียงใหม่

Abstract: Black glutinous rice bran contains many antioxidants. One of them is anthocyanin, which is gaining popularity and interest in many areas. Since free radicals occur within the body are the main cause of deterioration of the body, many companies have applied antioxidant in health food supplements. There are efforts to extract antioxidants for commercial use. Ultrasonic extraction is a new method for extracting antioxidants from rice bran with high yield and shorter extraction time. However, anthocyanins are limited in their color stability. Therefore, encapsulation techniques were used to help protect anthocyanin. The objectives of this thesis were to study the optimum conditions for anthocyanin extraction from black rice bran using ultrasound and reduces extraction time and to study the effect of encapsulating agents on anthocyanin microcapsules produced by spray drying method. Five solvents were studied: distilled water, 50% ethanol, 70% ethanol, 50% ethanol acidified with 1% (v/v) acetic acid, and 70% ethanol acidified with 1% (v/v) acetic acid were studied and found that the best solvent was 50% ethanol acidified with 1% (v/v) acetic acid. It was found that the extraction using 50% ethanol acidified with 1% acetic acid, controlling the ratio of solvent to solid, temperature and extraction time of 20: 1 (volume/weight), 30 °C, and 90 minutes, respectively, gave the highest amount of anthocyanin, total phenolics and DPPH radical scavenging activity. (4,710.38 mg C3G equivalent/g dry weight, 13,271.96 mg gallic acid equivalent/100g dry weight, 152.39 mg Trolox equivalent/100 g dry weight, respectively). The extracted solvent was used in the study of ultrasonic extraction. Four process parameters were studied by using the central composite design as follows: solvent to solid ratio (12.93 – 27.07 ml/g), extraction time (15.86 – 44.14 min), amplitude (23.79% – 66.21%) and pulse duration (2.17 – 7.83 s). It was found that the optimum conditions for the extraction of antioxidants from black rice bran were solvent to solid ratio of 22.91 mg/g, extraction time of 34.18 min, amplitude of 58.27% and pulse duration of 3 s that provided the highest responses including anthocyanin content 6,902.52 mg C3G equivalent/100 g dry weight, total phenolic content 20,453.85 mg gallic acid equivalent/100 g dry weight and DPPH radical scavenging activity 287.48 mg Trolox equivalent/100 g dry weight. In addition, the ultrasonic extraction process at optimal conditions provided anthocyanin content, total phenolic content and DPPH radical scavenging activity higher than the conventional extraction method (shaking) by 20.06%, 20.69% and 16.76%, respectively. This result suggests that ultrasound extraction is an effective method for the extraction of antioxidants from black rice bran and it could be good information for the development of nutraceuticals in the food and pharmaceutical industry.
Effects of 8 encapsulating agents on quality of microcapsules were studied: maltodextrin (MD), maltodextrin-gelatin (MD–GE), maltodextrin-whey protein isolate (MD–WPI), maltodextrin-gum Arabic, (MD–GA), modified starch (Sodium starch octenyl succinate, Hi), modified starch-gelatin (Hi–GE), modified starch-whey protein isolate (Hi-WPI) and modified starch-gum Arabic (Hi-GA). MD, MD–GA and MD-GA were found to be the potential encapsulating agents due to the highest encapsulation efficiency, low moisture content and low aw value. Except for the WPI-added samples, all microcapsules showed high water solubility and dispersibility with the highest values in MD sample. From the morphological study using the scanning electron microscope, it can be seen that all microcapsules were hollow spherical, small, scattered, and not clumped together.2023-06-01T00:00:00Zปัจจัยที่มีผลต่อการยอมรับการจัดการปุ๋ยเฉพาะพื้นที่ (ปุ๋ยสั่งตัด) ของเกษตรกรผู้ปลูกข้าวในอำเภอพาน จังหวัดเชียงรายวีร์สุดา ศรีจันทร์http://cmuir.cmu.ac.th/jspui/handle/6653943832/721502021-09-10T03:39:33Z2020-10-01T00:00:00ZTitle: ปัจจัยที่มีผลต่อการยอมรับการจัดการปุ๋ยเฉพาะพื้นที่ (ปุ๋ยสั่งตัด) ของเกษตรกรผู้ปลูกข้าวในอำเภอพาน จังหวัดเชียงราย

to July 2019. Data were analyzed using descriptive statistics such as frequency, percentage, maximum, minimum, mean and standard deviation. Analyze the relationship between independent variables and dependent variables by multiple regression analysis (Enter Multiple Regression
Analysis) The results showed that the majority of farmers are males with an average age of 52.90 years. Most of them completed primary education, an average of 24.12 years of experience in rice farming. Farmers' average income in 2018 is 4,133.63 Baht. Farmer still owes a household debt. There is 2.37 average household labor and additional labor. Farmers have an average agricultural area of 16.32 rai and most of them have rights documents. Most farmers do not have a social rank but they are other network members that can contact with relevant staff an average of 1 time per month. The average perception of news about the Site-specific Fertilizer Management was 2 sources. The average training of farmers was 1.58. Farmers were had knowledgeable about Site-specific Fertilizer Management overview at a high level and have an attitude about Site-specific Fertilizer Management overview at a positive attitude level. The study of factors affecting the acceptance of the results on the acceptance of Site-specific Fertilizer Management of rice farmer in Phan District, Chiang Rai Province. That the factors are related to the acceptance of Site-specific Fertilizer Management for rice farmers there are 3 independent variables which are the number of workers in the household in 2018 the receiving information Site-specific Fertilizer Management in 2018 and the attitudes of farmers to Site-specific
Fertilizer Management in 2018 significance affected the acceptance of customized rice-grower fertilizer technology (p<0.01) Problems, needs and suggestions the implementation, found that farmers have a problem with the cost of soil test kit is high expensive. The place to buy the soil test kit cannot be purchased in community. Lack of information and knowledge about soil series. And lack of experience in reading
values and compare the color bar to determine the amount of N P K in the soil, which is important to the accuracy and precision. The needs of farmers are training on Site-specific Fertilizer Management on a continuous basis in order to create a continuity of information and knowledge of soil series. Farmers needs the soil test kit to cheap price. And there is a suggestion that to have the government and private sectors support the soil test kit. To have a group to establish community shops in the form of a cooperative, sell the soil test kit and fertilizers at member prices. And dividing the participants training on Site-specific Fertilizer Management at sub-groups for everyone to practice.2020-10-01T00:00:00Z
