Abstract

Competitiveness of product innovation depends on how the company can answer the customers’ needs. To capture the right needs, product designer has to go and ask the customers and summary them into priority and translate the needs into technical requirement in order to produce the competitive product. At this era there are many kinds of drinks available in the market. Tea is one of the popular drinks for quite long. Different types of flavor tea created to find its market. This study is trying to offer a new product of Kombucha tea, a fermented tea. A method of Quality Function Deployment (QFD) was implemented to come out the right design of Kombucha tea which may absorb the customer needs. This was done through the questionaries and interview to the community. Based on this information then provide some technical requirements to produce the right quality Kombucha tea that are wanted by the customer. The results show customer requirement from the questionnaires 59% of respondents agrees that they buy Kombucha due to its taste. While 82% respondent agree on the Fuzzy sensation of kombucha taste. Packaging (Appearance), 58% like the package. And for Health benefit, respondents 83% agree. For easiness to get, respondents only gave 31%. The customer need should be transformed into Functional or technical measures. The study analyzed that there are 13 Functional aspects determined the end quality of Kombucha tea. This study presented on how to translate the customer needs into functional requirements to produce the right product.Keywords: QFD, kombucha, product development, customer needs

Abstract

Hand grip strength (HGS) is a well-known parameter of physical capability, clinical health status, and functional work performance. However, the scarcity of standardized, region-specific HGS data for Southeast Asian populations restricts the accuracy of health screening practices and the development of ergonomics and occupational safety guidelines. The aim of this study was to measure the dominant-hand HGS for healthy young adult women of Malaysia and Thailand, to compare the HGS of these two groups of women, and to investigate the relationship between age and anthropometric variables and the HGS. Researchers conducted a cross-sectional study involving 166 healthy women aged 20 to 39 years. This study recruited 92 participants from Malaysia and 74 from Thailand, primarily from university students and staff populations. Dominant-hand HGS was measured using a Jamar dynamometer (Sammons Preston, USA) while participants adopted a standardized standing position with the forearm in a neutral posture. Thai women demonstrated significantly greater mean HGS than Malaysian women (27.31 ± 6.96 kg vs. 23.64 ± 4.67 kg; p < 0.001), corresponding to an approximately 16% difference and a medium-to-large effect size (Cohen’s d = 0.63). Among Thai participants, HGS was significantly associated with palm circumference (r = 0.544), height, weight, and age. These variables collectively explained 44.8% of the variation in HGS. In contrast, only height showed a modest association with HGS among Malaysian participants. Meanwhile, the corresponding regression model demonstrated limited explanatory capability. These findings reveal population-specific differences in both HGS and its anthropometric correlates when assessed under standardized testing conditions. The study provides protocol-specific, preliminary reference data for healthy young adult Malaysian and Thai women, which may inform future development of validated, population-specific reference standards. By generating population-specific reference data, this study contributes to improving the accuracy and equity of health monitoring practices, in line with the objectives of United Nations SDG 3 (Good Health and Well-being).
