With the current cost of living situation in Thailand continuously rising, many recent graduates face challenges in managing their expenses in alignment with the increasing living costs. Food expenses, even for common street food, continue to surge with no sign of decreasing, despite improvements in raw material costs. Pay-Attention is a website platform designed to help recent graduates gain insights into managing and optimizing their food expenses effectively. It provides guidance on how to spend wisely, ensuring cost-effectiveness while maintaining adequate daily nutritional intake, without falling into monotonous eating habits.
ด้วยสถานการณ์ “ค่าครองชีพ” ของประเทศไทยในปัจจุบันมีแนวโน้มพุ่งขึ้นสูงเรื่อยๆ นับตั้งแต่ ยุคหลังโควิด-19 แต่ฐานเงินเดือนและรายได้ของนักศึกษาจบใหม่ ก็ยังคงมีฐานเริ่มต้นเหมือนเดิม ไม่ต่างจากหลายปีก่อน เป็นผลทำให้ประชากรที่พึ่งสำเร็จการศึกษา ในประเทศไทยจำนวนไม่น้อย ประสบกับปัญหาเรื่องการจัดการค่าใช้จ่าย ให้สอดคล้องกับค่าครองชีพอย่างเหมาะสมในปัจจุบัน ทั้งค่าใช้จ่ายคงที่ และค่าใช้จ่ายผันแปร ที่แปรเปลี่ยนไปตามวิถีชีวิตของแต่ละคน มากน้อย ตามความต้องการและรสนิยม ซึ่งเป็นค่าใช้จ่ายที่ต้องระวังและควบคุมการใช้จ่ายอย่างมีสติเสมอโดยเฉพาะค่าใช้จ่ายเรื่องอาหารที่แม้แต่ตามสั่งทั่วไปก็พุ่งสูงขึ้นเรื่อยเรื่อยไม่มีท่าทีจะลดลงแม้ต้นทุนวัตถุดิบจะปรับปรุงก็ตาม

This research focuses on the design and development of a high-power converter to regulate energy supply from solar cells (Photovoltaic: PV) to a hydrogen production unit (Electrolyzer), which is a crucial component in advancing renewable energy in alignment with the RE100 initiative. Specifically, this study targets Green Hydrogen, which is generated through the water electrolysis process using clean energy from solar cells, ensuring zero emissions and environmental sustainability. The proposed converter includes of a Three-Level NPC Inverter, transformer, Full-Bridge Rectifier, and LC filter to enhance the power quality supplied to the electrolyzer. The system's design and simulation were conducted using MATLAB and Simulink to evaluate circuit performance and analyze operational efficiency. Simulation was conducted using MATLAB and Simulink to evaluate circuit performance and analyze operational efficiency. Additionally, a microcontroller-based control system is integrated with a gate driver circuit to optimize the electrolysis process by reducing power losses. This proposed converter effectively converts PV energy into suitable voltage and current levels for the electrolyzer while maintaining high hydrogen production efficiency.

Major medical and veterinary pests including the mosquitoes, houseflies and cockroaches pose health problems for humans and mammals and create more visual obstruction. Therefore, this research discovered a formula of essential oils and active ingredients from herbal plants that are highly effective in controlling and eliminating these insects compared to chemical insecticides, are safe for non-target organisms living in the environment, and are stable and maintain the active properties of the compounds. These formulas can be developed into environmentally friendly natural products to replace or reduce the use of chemical insecticides.

Stirling engine is the external heated engine that heat is sup-plied externally to the heater part of the engine. Thus, Stirling cycle engine can be employed with various sources of renewable energy such as biomass, biofuel, solar energy, geothermal energy, recovery heat, and waste. The integration of gasifier, burner, and heat engine as a power system offers more fuel choices of each local area with potential resources resulting independent from shortage and cost fluctuation of fossil fuel. This research aims to investigate the integration of the Stirling engine with a wood pellet gasifier for electric power generation. Biomass can be controlled to have continuously combustion with ultra-low toxic emission. Stirling engine, therefore, is a promising alternative in small-scale-electricity production. Even though many biomass-powered Stirling engines were successfully constructed and marketed but these engines and the use of biomass resources as fuel for power generation are quite new concepts in some developing countries. Especially, the capital cost of this engine is high and unaffordable for installation compared to other power systems. Therefore, this research aims to the study attractive and feasibility of the compact Stirling engine with green energy.
