1. Introdu ct ion

Balinese :lromatherapy products such as aroma therapy scrub, incense, massage oil , soa p. :md many morc, were coped hi gh value of bus iness s in!.:e Bali has chosen as "The Best Spa Destil1:llio n of The World in 2009" on SENSE Maga%ine versio n f I ], In addition, from 2009 to 2013, about 2.803.18 1 visi tors !.::l llle to Bali with 9.5% increased for eadl year [2]. Considering th is conditioll. in order to winning the competition in this se!.:lOr, the need of the development of aromatherapy product has always been a challenge :lS well as the dl:lngin g of customer demands and expectat ions.

Basically, Balinese aromatherapy prQ(lucts have such uniqueness whi ch attracts the consuiller to buy thcm. This uniqueness refers to product Balinese sense which have a big cOll1ributionlO make the product become flnllous in the Illarket [3]. where Wijaya [4J said that the famous product refers to the product which w ulJ fu1fililhe customer need. Generally each customer has panicular criteria on wh ich they want 10 buy related to their personality, for instance, the extroven customers prcf!.: r gold color than black or grey. T he condition was supponed by Jordan [5] who said that people tend to illl:lgine products as having personalities and they te nd to express a preference fo r products tlmt they perceive as re ne!.: ting their own personalities , Anot he r aspect that has important role o n prod­uct development is product desi gn c lements which make the differences oflhe products and gives the impres­sion to customers direct ly [6],

As me nt ioned previous ly_ ilalinese sense. custome r personality. and des ig n clements considered as three important dimensions that llIake Balinese :lroma therapy produ!.:t become famo us ill the market. In this rese:lrch, K(lmei Engineering (KE) were chosen to synthesize these dimensions in orde r 10 develop Balinese arolllather­apy product design, In 1992, KE was introduced by Mitsuo Nagamachi as a product development method which translated !.:uSlOlllcr's impression into design speci lication [7J. The word Kallsei refe rs to Japanese Icnn

for the impression. fee ling, or the image of something. In thi s research, the word:.> that represent impression. feeling. or image of customers about Balinese aromatherapy product is identified as K(lIlsei Words (KW).

In thi s paper. Balinese ar01natherapy massage oil was c hosen as the rese:lrch object to develop. Fuzzy Quan­ti !ication Theory T ype I were used to synthesize three dimensions of Kallsci. By \Is ing this method, new des ign formulat io ns were generated and represented by linear model approac h. Furthermore, the recommendation o f design clement combinat ion and proportion were obtained directly based on c usto mer personality type. In particular this inform:ltion obtained would be powerful especia lly for product designer to develop the product in order to fulfil l customer subjecti ve pre ferences. Finally, according il s motivation, three main objectives were proposed illlhis research: (I) to ge nerate the new design conce pt of Balinese aromatherapy product. (2) to identify the re le va nt produc t design element, and (3) to ge nerate the quantificat ion model of aroma therapy

product design.

2, Met hodology

The methodology was designed to accomplish the research objectives. In this paper, Bal inese aronmthempy ma s­sage oil has been chosen as product domain 10 develop. Furthermore. the research methodology is representcd in Figure I .

The rescarch began with the identification of product domain as the research object. Afterward, the K \V were collected by interviewing the experts and followed by generating" new Balinese arolllatherapy design concept to achieve the fir.it objective. Then to achie ve second objective, design clements were identified for each sample collected :lI1d were evaluated accordi ng to the new design concept to obtain the relevant design clement. Finally, the new design concept and the product design clements wcre synthesized for cach customer pCr.iollality type to achicve the third research objecti ve. In this research. R language vcrsion 3. 1.3 were used as a tool of data pro­cessing.

3. New Design Concept Identificat ion

In this phase. firstly twelve K(III:;ei words have bccn collccted by means interviewing the experts which illustmted Balincse aromathcmpy product consisted of "Unique", "Allracting", "'Exotic", "'N atural", "Ba linesc product", "Luxurious", "Art istic", "Bri ght", "Tradi tional", "Fashionab le", "Eco-Fricndl y", alld "Transparent", Afterward, all thc Kmlsci words obtained have been evaluated by 30 customers of aroma therapy product using Likert scale (7

scale). Thus, the resuh of evaluation has been analyzed using Principal Component Analysis (PCA) melhod in order to reduce the dimension of K W collected and followed by generating a new concept of product design[8].

To dep loy PCA in this research, first ly, defines X as a matrix of K \V evaluation for fJ dimensions of KW which denotes as X = {Xt. X2 • . • . , x,,) where x/ € X. Then ca lculates the mean (jlj) of X for II product sample (i = 1,2, .. . , /I) which denotes as i\'I :; {PI,jll, ... ,jlp}' The next step is to calcu late the subtT3c t matrix between X and]'\"1 which denotes as Y = lv/,)') ..... )'p}. In order to sec the correlation between KW, compute the covariance of matrix of y which denotes as C wilh p x p dimensions. Thus. generate eigenvnl ue and eigenvector or c as fo rmul ated in (I) where eigcnvector denotes :tS n = 1",. be ..... bpj and eigenval ue denotes as i.:; (a/. a ..... ., (lp).

C * B =i.* B ( I )

According the resu ll of eigenva lue i .. it can be seen ,tbout how nlany principal component (PC) should be re. tained and the result of eigenvectors n showed the v(lille o f component' s loadi ng components. The result eigen. value of each component is reprcsented in Fi !;;llre 2 and the result of componcnt loading factors in two dimension of PC named PCA variables f;Ictor map is represented in Figure 3.

According PCA rcsult . one princ ipal component which has eigcnvalue above I was gencrated to represcnt 79.5 1 % orall the Kall.l"ei words as represe ntcd in Figure 2 and the KOII.l"ei words were grouped into their principal component as seen in Figure J" . Based on PCA result, '"Balinese Traditional" (priucipn l component I) has been chosen to cope the group as a new dcsign concept of Balinese aromatherapy product as the answer oflirst objective in th is research.

4. Rclcvant Design Elcmcnt Idcnt ili catioll

In order to answer the second research object ive. 25 Balinese aromatherapy massage o il have been coll ected. The resu lt o f design clement identification phase showed that there were 12 categories with 34 variance of design clements which is represented in Table I . Rclicfa lgori thm [9J was deployed to determine which relevant product design clements lo r BT image. Basically, Relief method is a feature weight based mcthod inspi red by instance· based leaming which detccts those feature which nrc stat istically relevance to the larget concept [91.

6. Conclusion

In this paper, a research has been conducted on Balinese arommherapy massage oil to demonstrate how Kame; Engineering using FQTTI analysis were applied 10 ussist product designers in deci sion maki ng oflhe new product design for e:lch personality type. The result of peA method showed the cxtnlctioll ofKW collected which reduced 12 K W into one word which represented:1 new design concept of Balinese arom:lther:tpy product named "Bal inese Traditional" ' (BT). By using Relief ulgorithm. ten relevant design elements have been generated which consisted of top shape, body shape. bottle height and width ratio. copped ornament and bottle height ratio. bottle material. cap color. omamenl ilem used . rool in the bottle existence. bottle transparency, (lnd label position . According to the result of FQTT I analysis, a linear <luant itativc model has bcen built for cach personalily type to explore the relationship between customer's emotional fcelings and product design elements. From these model, the design support information has been generated 10 assist product designers in decision Illaki ng for Ihe new Balinese product des ign. In genera l. the resu lt showed Ihat all des ign specifi cation of B;llillcse arol1llt lh cr;IJlY product were speci fi c for each persona l ity ;1IId most of them were productive as the new design ru les. By closer imp:liring thc product development o f 13alinese arol1l31herapy wi th customcr personality type, a higher degree of globa l demand may be expectcd both for business and community. For future research challenges are consisted of how 10 scale up with a reliable manufacturing and financial engineering process within an integrated production systcm.
