Threadfin breams is an economically important fish that can be found in fisheries in both the Gulf of Thailand and Andaman Sea and is cheap. In addition, the consumption of raw fish as sashimi is increasingly popular in Thailand. Therefore, it is necessary to promote its consumption to increase its value. This study investigated the preservation of threadfin breams (N. furcosus) for raw or sashimi consumption. The preservation of threadfin breams consisted of Ikejime (K) and cold seawater (S) methods, and the preservation of the fish by Gutting (G) and whole (W) and storing for 3 days on ice (I) or in a refrigerator (F). The freshness quality of threadfin breams was evaluated by sensory, physicochemical (TVB-N, TMA-N and pH), freshness index (Ki-value) and microbiological methods. It was found that after being stored for 3 days, the KGF group of threadfin breams had the highest overall sensory score, which was 8.36±0.80 points, and the KWI, SWI and SWF groups of threadfin breams had the lowest overall sensory scores, which were 8.13±0.77, 8.13±0.77 and 8.13±0.81 points, respectively. And the overall sensory scores of all experimental groups of fish increased significantly (p<0.05). The TVB-N value of threadfin breams in KGF group had the lowest TVB-N value, which was 1.37±0.93 mg nitrogen/100 g sample. The threadfin breams in SGI group had the highest TVB-N value, which was 2.36±1.15 mg nitrogen/100 g sample. The TVB-N of fish in all experimental groups increased significantly (p<0.05). The TMA-N value of threadfin breams in KGF group had the lowest TMA-N value, which was 1.56±0.88 mg nitrogen/100 g sample. The threadfin breams in SWF group had the highest TMA-N value, which was 2.17±1.22 mg nitrogen/100 g sample. The TMA-N of fish in all experimental groups increased significantly (p<0.05). The pH value of threadfin breams in KGF group had the lowest pH value, which was 6.40±0.12. The threadfin breams in SWF group had the highest pH value, which was 6.78±0.25. The pH of fish in all experimental groups increased significantly (p<0.05). Ki value The threadfin breams in KGF group had the lowest Ki value, which was 9.05±0.73%. The threadfin breams in KWI group had the highest Ki value, which was 12.88±4.19%. The Ki value of all experimental groups of fish increased without statistical significance (p>0.05). In terms of freshness quality in microbiology, it was found that in all experimental groups, Salmonella spp., S. aureus, B. cereus, C. perfringens and E. coli were found in all experimental groups of threadfin breams. All types of microorganisms in all groups of threadfin breams increased with statistical significance (p<0.05). When compared with the freshness quality criteria in terms of sensory, chemical, physical, freshness index and microbiology, it was found that all groups of threadfin breams were very fresh and suitable for raw consumption during the preservation and storage for 3 days. After 3 days of storage, the threadfin breams should be consumed cooked because the freshness quality of the fish is not suitable for raw consumption due to the increase in various parameters. The increase in various parameters is due to the deterioration of the fish and the activities of microorganisms. Therefore, threadfin breams is suitable to promote raw consumption within 3 days of storage. In addition, fish preservation, especially by Ikejime method, then cutting open the belly and storing in the refrigerator, can help improve the freshness of the fish. The results of this study can be used to develop techniques for preserving fish after capture for fishermen and can promote the increase in the value of threadfin breams in the future.

This research aims to study the waste management process of horse manure, the production process of organic fertilizer from horse waste, and opinions on the use of innovative organic fertilizer from horse manure. A mixed-method approach, combining qualitative and quantitative research, is employed. The organic fertilizer is produced from horse manure, which is a waste that incurs disposal costs. Through the fermentation process, it is transformed into an environmentally friendly fertilizer containing essential nutrients beneficial to plants. According to the laboratory analysis of the organic fertilizer conducted by the Soil Science Laboratory, Faculty of Agricultural Technology, King Mongkut's Institute of Technology Ladkrabang, it was found that organic fertilizer from horse manure contains essential nutrients for plant growth, including macronutrients, secondary nutrients, and micronutrients. This reflects the potential of horse waste management, the production process of organic fertilizer from horse manure, the efficiency of the organic fertilizer, and strategies for adding value to expand its commercialization.

Capsicum chinense is a high-potential economic crop in the food and pharmaceutical industries due to its role as a primary source of capsaicin, a bioactive compound with significant physiological effects. However, capsaicin levels and fruit quality will be influenced by genetic factors, environmental conditions, and genetic-by-environment (G×E) interactions, leading to variability in capsaicin biosynthesis. This study will aim to analyze the impact of different environmental conditions on the growth, fruit quality, and capsaicin content of C. chinense ‘Scotch Bonnet’. The field experiments will be conducted at the demonstration plots of the Faculty of Agricultural Technology, King Mongkut’s Institute of Technology Ladkrabang, during two growing seasons: July–October (rainy season) and December–April (dry season). Four condition environments will be evaluated, and environmental parameters such as temperature, relative humidity, and light quality will be monitored to assess their effects on plant physiology and capsaicin biosynthesis. Additionally, an F1 hybrid breeding program will be established using six parental lines through a Half-diallel mating design, generating 15 hybrid combinations. The general combining ability (GCA) and specific combining ability (SCA) will be assessed to identify promising hybrid combinations with high and stable capsaicin content and yield. The findings from this study will be expected to provide valuable insights into optimizing cultivation conditions for high-pungency chili production and supporting the development of F1 hybrid seeds with commercial viability and consistent capsaicin levels.

This research confirms the potential of bamboo fiber as a sustainable raw material for the textile industry, demonstrating exceptional properties that meet both functional requirements and environmental friendliness. The study focuses on integrating sustainability concepts with material innovation, encompassing fiber property analysis, production process development, and product design. The research objectives were to: 1) develop the properties of bamboo fiber for production; 2) study factors in designing environmentally friendly textile products from bamboo fiber; and 3) forecast future prospects for environmentally friendly textile product design using bamboo fiber. The findings revealed that 60-day-old bamboo possessed optimal properties for fiber separation, with an average fiber size of 5.32 μm, smaller than other natural fibers, resulting in superior moisture absorption and ventilation properties. When blended with recycled polyester fiber in a 30:70 ratio, the yarn exhibited strength and unique tactile characteristics. Although the antibacterial properties against Staphylococcus aureus were low, the fibers demonstrated excellent whiteness and softness. Factor analysis identified four key components in product design: Local Materials, Green Products, Healthy, and Sustainability. Consumer satisfaction evaluation of the prototype products showed high levels of acceptance, with the model explaining 84.7% of consumer satisfaction. The developed production process reduced chemical usage and hazardous waste. Furthermore, utilizing fast-growing bamboo minimized long-term environmental impact, contributing to sustainable development in Thailand's rural communities across economic, environmental, and occupational stability dimensions. The research demonstrates that developing bamboo fiber blended with recycled polyester creates sustainable products that meet consumer demands for health consciousness, local material utilization, and green product promotion. Commercial implementation of these products can enhance economic value and promote environmentally friendly product development in the future.
