This experiment aimed to study the suitable types of polymers for coating with chlorophyll extract and the quality of cucumber seeds after coating. The experiment was planned using a Completely Randomized Design (CRD) with four replications, consisting of five methods involving seeds coated with different types of polymers: Polyvinylpyrrolidone, Sodium Alginate, Carboxy Methyl Cellulose, and Hydroxypropyl Methylcellulose, each polymer being coated alongside chlorophyll, with uncoated seeds serving as the control method. The coating substance was prepared by extracting chlorophyll from mango leaves, then mixed with each type of polymer at a concentration of 1%, using an 8% concentration of chlorophyll extract. The properties of each coating method, such as pH and viscosity of the coating substance, were examined before coating the cucumber seeds with a rotary disk coater model RRC150 at a coating rate of 1,100 milliliters per 1 kilogram of seeds. Subsequently, the seeds were dried to reach the initial moisture level using a hot air blower, and seed quality was assessed in various aspects, including seed moisture, germination rate under laboratory conditions, germination index, and seed fluorescence under a portable ultraviolet light illuminator, as well as light emission spectrum analysis using a Spectrophotometer. The experiment found that each type of polymer could be used to form a film together with chlorophyll, which had appropriate pH and viscosity for the coating without affecting seed quality and showed fluorescence on the seed surface both under portable ultraviolet light and spectral emission analysis with a Spectrophotometer. Using HPMC as the film-forming agent with chlorophyll was the most suitable method, enhancing seed fluorescence efficiency.
สารเรืองแสงที่นิยมใช้เคลือบเมล็ดพันธุ์ในปัจจุบันมีหลายชนิด เช่น Rhodamine B, Curcumin, Auramine O แต่สารเหล่านี้บางชนิดหากใช้ไปเป็นเวลานานอาจเป็นพิษต่อร่างกายมนุษย์ หากสะสมในร่างกายอาจก่อให้เกิด oxidative stress ซึ่งกระตุ้นให้เซลล์เกิดการเสียหาย เพิ่มความเสี่ยงของโรคบางอย่างได้ ในงานวิจัยนี้จึงเลือกใช้สารสกัดจากธรรมชาติมาใช้เคลือบเมล็ดพันธุ์ คือ สารสกัดคลอโรฟิลล์ มีข้อดี คือ หาได้ง่าย มีวิธีการสกัดที่ไม่ซับซ้อน แต่ข้อจำกัดของสารสกัดคลอโรฟิลล์คือมีความสามารถในการเคลือบร่วมกับพอลิเมอร์ได้บางชนิด อาจทำให้ประสิทธิการเรืองแสงมีคุณภาพลดลง ดังนั้นการวิจัยนี้จึงมีวัตถุประสงค์เพื่อหาชนิดของพอลิเมอร์ที่เหมาะสมในการนำมาเคลือบร่วมกับสารสกัดคลอโรฟิลล์แล้วไม่ส่งผลต่อประสิทธิภาพการเรืองแสงและคุณภาพของเมล็ดพันธุ์

One of the most important aspects of responding to a medical case is the response time. In general, most fatalities are due to the patient not being able to reach the hands of the doctor in time. This also includes the arrival of medical equipment to the scene. The human brain will start to degrade in function after 3 minutes of oxygen starvation which conventional road transportation method first responders presently use is usually unable to reach the site in this golden 3 minutes, resulting in fatalities during transport or before the arrival of first responders at the scene. Therefore, medical equipment transport by fully autonomous aircraft is explored. This is done through drone deliveries which is much quicker than road methods as the equipment could be flown straight to the site as it is not affected by traffic, road conditions, and navigation. In this project, we will explore an aerial delivery system for medical equipment such as Automatic External Defibrillators (AEDs), First aid equipment, and other small requested medical devices. This will be done through a DJI drone platform and their SDK application. The main goal for this project is to decrease the response time by using an autonomous aerial drone to deliver medical equipment.

In an era where sustainability is at the heart of business operations, eco-friendly packaging is gaining increasing attention. This research explores sustainable business models for alternative packaging, focusing on the case of corn-based paper, an innovation that effectively replaces conventional plastic packaging. The study analyzes key factors that enable businesses using natural raw materials to remain competitive in the market, as well as the growth potential of sustainable packaging compared to plastic-based alternatives. Additionally, it examines the factors influencing consumer behavior in choosing eco-friendly products and evaluates the impact on profitability and social responsibility. This research employs both qualitative and quantitative methods, including case studies of businesses utilizing alternative materials, in-depth interviews with industry experts, and consumer behavior surveys. The findings are expected to provide insights into the business potential of corn-based packaging, strategies for market expansion, and approaches for long-term sustainability. The results of this study will serve as a valuable reference for entrepreneurs seeking to develop green businesses and policymakers aiming to promote sustainable packaging in the market.

This study aimed to develop a website for collecting and organizing data on Young Smart Farmers in Chanthaburi Province. Data were collected through structured interviews with a sample of 30 participants. The information obtained was categorized and utilized to develop the website, which was subsequently disseminated to farmers and other stakeholders. The study also assessed user satisfaction with the website through a questionnaire, with data analyzed using descriptive statistics, including frequency, percentage, mean, and standard deviation.The results indicated that the sample comprised an equal proportion of male and female participants, with the majority (50.00%) aged between 36 and 40 years. Most respondents were Young Smart Farmers from the districts of Khlung, Laem Sing, and Kaeng Hang Maeo, each representing 13.33% of the sample. The majority of participants had attained a bachelor’s degree or equivalent (60.00%) and were primarily engaged in agricultural occupations (73.33%). The findings on user satisfaction with the website revealed a high level of satisfaction across all dimensions, ranked as follows 1) Website usability (Mean 4.97), 2) Overall satisfaction (Mean 4.93), 3) Content quality (Mean 4.91), 4) Practical benefits and applicability (Mean 4.87), and 5) Design and layout (Mean 4.85).
