Prediction of Cement Sales Using the Linear Regression Model Equation Method (2022-2024): A Case Study of Building Material Retail Stores in Rattaphum District, Songkhla Province

Wed, 30 Apr 2025 00:00:00 +0700

This research aimed to develop and evaluate a simple linear regression model for forecasting monthly cement sales in Rattaphum District, Songkhla Province, using data from January 2022 to September 2024 (n=33). The analysis revealed the most suitable equation to be indicating a statistically significant decreasing trend (p < 0.001) in sales by an average of 7.35 sacks per month. The relationship between time and sales showed a moderate negative correlation (r = -0.6613). However, the model's explanatory power was limited, with R² = 0.437 (43.7%), suggesting that other factors not included (e.g., economic conditions, seasonality, competition) significantly influence sales. Furthermore, checks of the underlying assumptions revealed important limitations, particularly significant positive autocorrelation, a common issue when applying basic models to time series data. The derived equation was used to forecast future sales. While subject to these limitations, these forecasts can provide preliminary information for decision-making in production planning, inventory management, and marketing strategy development, provided they are considered alongside other factors and the model's constraints.

Efficiency of Concrete Mixer Blades for Enhanced Cellular Lightweight Concrete Production: A Comparative Experimental Analysis

Wed, 30 Apr 2025 00:00:00 +0700

This research aimed at enhancing a rotary drum concrete mixer blade for cellular lightweight concrete (CLC) production. The study systematically examined the influence of blade design on critical mixing parameters, including mixing duration, compressive strength, and dry density. Experimental trials were conducted on cellular lightweight concrete specimens with varying dry density levels of 700, 800, 900, and 1,000 kg/m³, maintaining a constant water-to-cement ratio of 0.45 and a foam agent density of 47 kg/m³. A 260-liter capacity concrete mixer was powered by a 1.5-horsepower electric motor rotating at 24 revolutions per minute. A comparative analysis was performed using three distinct blade designs to evaluate their performance characteristics. The results demonstrated that the three-row blade design generated the highest shear forces during the mixing process, consequently yielding optimal compressive strength across all tested dry density ranges. This research provides valuable insights into the critical role of blade geometry in improving the mechanical properties and overall performance of cellular lightweight concrete mixtures.

This research aimed to enhance competitive capabilities and promote the exchange of knowledge and experience in business operations, while fostering activities that drive productivity and innovation within the network of processed organic fertilizer industry enterprises under the supervision of the Industrial Promotion Center Region 10. The study revealed that 13 businesses participated in the activities. The satisfaction assessment of the activities, conducted by 12 businesses, demonstrated a 92.31% satisfaction rate, with an average satisfaction level of 4.92, representing 98.40%. Participants also expressed 98.40% satisfaction with applying the acquired knowledge to their network's data and knowledge activities. Furthermore, 95.00% of participants found the knowledge gained to be applicable and beneficial for revenue generation; 100.00% utilized the meeting summaries for their group's benefit; and one establishment successfully applied the outcomes of this activity to establish an organic fertilizer industry network.

Kriangsak Khiaomang — Wed, 30 Apr 2025 00:00:00 +0700

The objectives of this research are to: 1) promote the use of technology and research for community benefit; 2) encourage the adoption of innovative production processes within communities; 3) upgrade products through integrated knowledge and blended local wisdom; and 4) enhance the value and significance of products by using intellectual property and petty patents for the benefit of society. The research is qualitative and involves the transfer of technology to communities through the integration of traditional wisdom with modern design knowledge. The target groups are two communities in Sa Kaeo Province: the Faek Noen Lao Community Handicraft Enterprise and the Ban Wang Yao Weaving Group Community Enterprise. The research findings revealed that the communities were able to develop at least three new handicraft products and demonstrated the potential to create and design integrated products combining local wisdom with technology and product design patents. As a result, the communities submitted two new patent applications and expanded these results to sustainably enhance the grassroots economy.

Branding and Packaging Design to Enhance Herbal Products of Community Enterprise Group, Ban Khao Yai Pluang Thong Subdistrict, Bo Thong District, Chon Buri Province

Miyoung Seo — Wed, 30 Apr 2025 00:00:00 +0700

This research aims to: 1) create a logo for the Ban Khao Yai community, Pluang Thong Subdistrict, Bo Thong District, Chonburi Province; 2) integrate the development of lemongrass, galangal, and turmeric herbal products in collaboration with government agencies; 3) design packaging for such herbal products; and 4) transfer technology and knowledge to the Ban Khao Yai community. The research methodology was divided into three phases: Phase 1 creating the brand logo; Phase 2 product development and packaging design; and Phase 3 knowledge transfer to the community. The results showed that 1) the identifies used in the logo design were elephants and mountains; 2) the product development, in collaboration with the Chonburi Agricultural Office, the Bo Thong District Agricultural Office, and the Ban Khao Yai Self-Reliant Community Enterprise, leading to the development of lemongrass tea, galangal tea, and lemongrass, galangal, and turmeric herbal soaps; 3) two types of packaging were designed: one for lemongrass and galangal herbal tea containing 20 sachets, and one for the herbal soap made from lemongrass, galangal, and turmeric, containing one bar; and 4) knowledge transfer to the Ban Khao Yai Self-Reliant Community Enterprise involved hands-on training workshops on processing herbal lemongrass and galangal tea, as well as producing herbal soap made from lemongrass, galangal, and turmeric.
