This study aims to develop alginate-based hydrogels reinforced with carrageenan and gellan gum as composite materials for oral drug delivery. Alginate, a naturally derived polymer from brown algae, forms a gel upon exposure to cations such as calcium ions, enhancing the hydrogel’s structural integrity. Carrageenan and gellan gum, both polysaccharides, further improve stability and encapsulation efficiency. This research investigates the physical properties, mechanical strength, encapsulation capacity, and swelling behavior of hydrogel beads under simulated gastrointestinal conditions. The findings are expected to demonstrate that incorporating carrageenan and gellan gum enhances the durability and stability of hydrogel beads while enabling controlled release of active compounds in the gastrointestinal tract. These advanced hydrogel beads hold significant potential for applications in the food and pharmaceutical industries as effective oral delivery systems for bioactive substances.

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).

This study focuses on the use of ceramic tile powder as a cement replacement material in concrete at an appropriate ratio. The objective is to investigate the properties of replacing cement with tile powder and to determine the optimal mixing ratio of tile powder in cement mortar that can yield properties equivalent to or superior to conventional cement mortar. The experiment involved preparing cement mortar samples by replacing cement with two types of ceramic tile powder waste from tile manufacturing plants: waste tile powder and rectified tile powder. The mixing process was divided into two parts: Part 1 used a cement and tile powder ratio, while Part 2 used the results of the strength analysis from Part 1 to adjust the ratio accordingly. Various properties were tested, including specific gravity, normal consistency, setting time, tensile strength, and compressive strength. The results of the study revealed that replacing of cement with rectified tile powder provided the highest tensile and compressive strength, comparable to that of conventional cement mortar. Therefore, the use of ceramic tile powder as a replacement can enhance compressive strength while reducing cement usage, which has positive environmental implications by decreasing greenhouse gas emissions from cement production. Furthermore, this approach promotes the effective use of waste materials from the ceramic industry, contributing to the sustainability of the construction industry.
