Abstract. Prior researchers indicate that mental load is one of the most important contributors to a traffic accident. The aim of the paper is to investigate the impact and the correlation of road condition and driving experience on driver's mental workload. The driving test consists of 3 road complicity situation (urban road, highway, rural road) with 26 drivers with average 21 years old in different experience level (average 4.08 years' experience). NASA TLX questioner is used as subjective driver's mental load measurement with three dimensions relate to the demands imposed on the subject (Mental, Physical and Temporal Demands) and three to the interaction of a subject with the task (Effort, Frustration, and Performance). There are 3 cameras placed on the left side, right side and front car to identify the road condition. According to experiment, it was found that drivers felt that frustration level, business, and mental-demand factors dominate the impact on high-level workload (96.15%). Highway road conditions provide an average overall workload score of 62 (OWS) which was better compared to city road (OWS = 69) and rural road (OWS = 66). Based on street complexity, it is necessary to improve road conditions that resemble highway road by reducing potential hazard. Keywords: Mental driving workload, NASA TLX, Overall workload score (OWS) I IntroductionDriving is main human activity which is conducted to support daily activities and mobility in the shortest time possible. This initiated large government investment in providing safe and convenient transportation system. The driving complexity causes road accidents, not only due to physical factors such as cars and road conditions but also due to human factors themselves such as human error and excessive stress levels. Fastenmeir and Gstalter [1] research define that the complexity of driving depends on elements such as road design (highway, rural road, city road), road layout (straight, curved, inclined, junction) and traffic flow (high density). The study of the situation and the pattern of the relationship between drivers with cars and driving environments in order to reduce or avoid possible risk. The driver's ability to meet driving needs becomes an important capital in realizing safety driving [2]. The ability to adapt quickly, such as reducing speed, changing the direction of the vehicle is very much dependent on driving experience and mental condition (load) of the driver.Schlegel [3] defines driving workload as the total amount of resources or driver's ability to achieve a driving task. Further driving workload reflects the driving need to achieve performance tasks that depend on individual drivers and skills. Driving workload depends on the task (demand, complexity, and difficulties), drivers (age, fatigue, abilities, experience, etc.) and environment (dynamic/changing, familiar, etc.). Total driving workload consists of every aspect relating to driving task and nondriving task [4]. Driving tasks consist of street monitors making lateral/longitudinal ac...

I. PENDAHULUAN 1Tempat tinggal dapat diatikan sebagai tempat perlindungan dan beristirahat yang dapat menjamin kepentingan keluarga dan memberikan kemungkinan untuk bersosialisasi.Lebih dari itu, tempat tinggal diharapkanjuga memberikan ketenangan, kesenangan, kebahagiaan, dan kenyamanan pada segala peristiwa hidup penghuninya (Frick, 2006 : 24-07-2017 Diperbaiki: 23-04-2018 Disetujui: 25-06-2018 yang dapat merugikan kesehatan (Hindarto, 2007). Permasalahan muncul ketika hal-hal sebelumnya tidak tercapai, sebagai contoh dikarenakan sepatu dan sandal yang berserakan, sehingga menyebabkan kenyamanan dan estetika tempat tinggal berkurang.Selama ini sebenarnya sudah terdapat solusi dalam menyimpan dan merapikan sepatu ataupun alas lainnya, yaitu dengan rak sepatu (Gambar 1). Menurut hasil survei pendahuluan dengan menggunakan wawancara dan kuesioner, serta studi pustaka, penggunaan rak sepatu saat ini dikatakan masih kurang efisien. Hal ini terjadi karena apa yang diharapkan oleh pengguna belum dapat terpenuhi oleh produk yang sudah ada tersebut, misalnya kebutuhan rak yang tertutup, nyaman, dan menarik.Selain itu, pengguna menyampaikan keluhan lainnya seperti kapasitas yang terbatas dan material rak yang tidak kokoh. Penelitian ini bertujuan untuk

One product that has a short life cycle is a fashion products where the consumer desires can influence the company's decision to develop the product. Batik is one of Indonesian local wisdom, which not all of batik in Indonesia has a high popularity, such as Batik Malangan. Kansei Engineering method used in this study to identify the implicit desire of users in the form of feeling, emotion, or perception when interacting with Batik Malangan. By implementing the procedures Kansei Engineering Type I, there are 30 words that appear using 14 stimulants of Batik Malangan. Statistical data analysis performed using multivariate analysis. The most important kansei words chosen by using Factor Analysis and Principal Component Analysis. In this study, a total of 61 respondents who are citizens of Malang and from outside Malang participated. For customers, the main attraction at the Batik Malangan is the motive, whether the primary motive, secondary motive, nor the isen motive. Until now, Batik Malangan's motive not yet have a characteristic, so it is less well known by customers. Overall, this study contributes to that Kansei Engineering is a method that can be used to capture the feeling of customers mainly on customized products. With so many product variations based on local wisdom should be able to be developed by actually capturing the customer's desire, not only explicit but also implicit.
