This research aimed to study the priority of factors influencing brand design to add value to crispy fish products from the entrepreneurs' perspective. The study utilized the Analytic Hierarchy Process (AHP) to analyze and determine the weights of both main and sub-factors. The analysis included 6 main factors and 22 sub-factors. The results revealed that the main factors with the highest weights were the information on the packaging, packaging color, and label color, respectively. These findings can be applied to other products, as every product requires a brand to provide preliminary information that informs consumer purchasing decisions.

LOGO DESIGN FROM COMMUNITY ECONOMIC PLANT IDENTITY: A CASE STUDY OF PHROM KHIRI COMMUNITY

Chatchai Kaewdee — 2025-08-28

This research aims 1) to explore and gather data concerning the key economic plants and their associated identities within the Phrom Khiri community, 2) to analyze suitable components and concepts for incorporating economic plant identities into logo design, and 3) to propose logo design guidelines derived from the economic plant identities for the Phrom Khiri community, along with an initial evaluation of the designs by design experts. The case study focuses on the Phrom Khiri community in Nakhon Si Thammarat Province, a community distinguished by its prominent economic plants, namely Matat (Brown Gardenia) and Fig. The study commenced with the collection of data on the community's main economic plants and an analysis of the cultural, historical, and lifestyle identities related to these plants. Subsequently, entrepreneurs, artisans, and local wisdom experts were surveyed and interviewed to comprehend their needs and perceptions regarding the integration of economic plant identities into logo design, including an initial evaluation of the logo designs by design experts. The research findings indicate that effective logo design should integrate natural elements, shapes, colors, and symbols that represent the economic plants, concurrently with storytelling and community values. The expert evaluation results demonstrated a mean score ( )of 4.33 for clarity in communicating identity, aesthetics, and usability, with a standard deviation (S.D.) of 0.58, which is interpreted as 'very good'. Furthermore, the mean score () for uniqueness was 3.33 with a standard deviation (S.D.) of 0.58, interpreted as 'fairly good'. The proposed design guidelines can be applied to create distinctive logos, enhance product value, and sustainably promote the identity of the Phrom Khiri community.

WASTE REDUCTION AND PROCESS CAPABILITY EVALUATION IN RUBBER MIXING VIA LEAN SIX SIGMA: A CASE STUDY IN A THAI RUBBER FACTORY

Nipas Leenatham — 2025-08-28

The objective of this research is to enhance the productivity of the rubber-mixing process in the production department, while adhering to feasible constraints and required standards. An analysis of the existing process revealed that productivity was below the standard range, primarily due to inefficient and complex work procedures, excessive pallet consumption for handling both rubber sheets and scraps, overuse of manual labor, high error rates in the semi-automatic weighing process, dependency on numerous forklifts, and excessive waiting times and inventory levels. After implementing improvements by integrating the Lean Six Sigma approach and using the seven quality control tools, a fully automatic weighing system was developed for continuous rubber weighing. The production line was also re-engineered to create a continuous flow between the rubber washing and mixing processes. The results showed that the Process Capability Index (C_pk) was 1.35, indicating a highly capable process. The validation confirmed the elimination of waste in the mixing process. The confidence interval for the process was established as 1.07<C_pk<1.62. The estimated break-even point for the project was 2.28 years.
