A high-pressure gas storage tank made from composite materials, including carbon fiber, resin, and plastic, is designed for storing compressed natural gas (CNG) or hydrogen. This type of tank is classified as a Type IV high-pressure vessel. In this research, it is designed to operate at a pressure of 250 bar for the transportation of compressed natural gas.
การบรรจุก๊าซที่ความดันสูงต้องใช้บรรจุภัณฑ์ที่มีความแข็งแรง การใช้ถังที่ผลิตจากโลหะถูกนำมาใช้ในช่วงแรกๆ แต่ปัญหาที่ตามมาคือน้ำหนักมากทำให้สิ้นเปลืองเชื้อเพลิงในกรณีที่นำไปติดตั้งบนยานพาหนะ จึงเกิดการพัฒนาถังความดันที่พัฒนาจากวัสดุประกอบขึ้นซึ่งจะช่วยลดน้ำหนักของบรรจุภัณฑ์และการกัดกร่อนเกิดขึ้นน้อย

The aim of experiment was to study the pyrolysis oil derived from sorted landfill plastic waste that had been buried for 15 years by the Nonthaburi Provincial Administrative Organization. The pyrolysis oil was produced using a Fixed-Bed Reactor at 450 °C for 1.5 hours with LPG as the feedstock, with the goal of using the pyrolysis oil as an alternative fuel. The experiment was conducted under four different conditions : (1) plastic waste buried in a landfill that has not been washed but has been reduced in size, (2) plastic waste buried in a landfill that has been washed and has been reduced in size, (3) plastic waste buried in a landfill that not has been washed and has not been reduced in size, (4) plastic waste buried in a landfill that has not been washed and has been reduced size, with activated carbon used as a catalyst. The experiment revealed that three products were produced : Oil, gas, and char in different quantity. The pyrolysis oil were compared in terms of quality based on pH, Heating value, Moisture content, Functional group, and Chemical Composition. The pyrolysis oil we obtained will be referenced according to the criteria from the Department of Energy Business. The analysis results of the pyrolysis can explain which conditions are suitable for replacing fuel oil in industrial It is therefore one of the approaches that helps manage plastic waste in landfills, reducing the quantity by converting it into usable energy.

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).
