User experience evaluation on the usage of commuter line train ticket vending machine

To deal with the increase of mass transportation needs problem, PT. Kereta Commuter Jabodetabek (KCJ) implements Commuter Vending Machine (C-VIM) as the solution. However, this implementation is causing problems and long queues when the user is not accustomed to using the machine. The objective of this research is to evaluate user experience after using the commuter vending machine, to analyze the existing user experience problem, and to achieve a better user experience design. User experience is measured using both quantitative and qualitative measurements. The quantitative measurement comprises user performance metrics, such as task success, time on task, error, efficiency, and learnability. The qualitative measurement includes system usability scale questionnaire (SUS), questionnaire for user interface satisfaction (QUIS), and retrospective think aloud (RTA). This study shows that C-VIM has a bad performance and user experience. Interface redesign using activity relationship chart (ARC) was proposed and resulted in a better performance and user experience.

Perancangan Peta Jalan Pengembangunan Industri Hasil Pertanian pada Wilayah Kabupaten dengan Metode VRISA dan Rantai Nilai

.Industry development is an alternative in social welfare improvement of a region. This research was conducted to develop a road map of industry development in Kabupaten Bengkayang, West Kalimantan. VRISA (Value, Rare, In-imitabillity, Substitutability and Appropriability) framework used to determine appropriate industrial products to be developed. Based on value chain method, the development strategy was constructed into main value chain and supporting value chain strategy. Output of analysis showed that corn-based product was preferred by VRISA framework, so it needs to be developed as appropriate industry for Kabupaten Bengkayang. There are three stages of industrial development in the corn-based industry, namely initial phase (basic foundation establishment), main phase (implementation), and final stage (harvesting). Time frame for all stages takes five years.

Analysis of Vertical Multiplier on Revised National Institute for Occupational Safety and Health (NIOSH) Lifting Equation for Male Workers in Indonesia Industry

Manual Material Handling (MMH) is a risky activity that causes low back pain and has become a worldwide phenomenon, not only in developed countries, but also occur in developing countries. One effort to reduce the injury caused by MMH is the Reccomended Weight Limit (RWL) equation, published by NIOSH. However, NIOSH equation is more tested and researched in European and America. Therefore, it is necessary adjustment for Indonesia people. In this paper, the author analyze the vertical multiplier factor in NIOSH equation for male workers in Indonesia. Multiplier factor is assessed using three criterias. There are biomechanics, physiology, and psychophysical. The result of this study is form of vertical multiplier equation, i.e VM = 1 - 0.0310083 (68-V) and VM = 1 - 0.00708215 (68-V) for an elevation below the knuckle.

Work System Improvement of Evacuation Process Conducted by Emergency Medical Technicians Using Virtual Environment Modeling

The work of emergency medical technicians (EMT) during patient evacuation involves lifting task in an emergency situation, which results in the increasing risk of musculoskeletal disorders such as low back pain. The purpose of this research was to investigate the workplace and ergonomic aspect that influence work posture of the EMT using simulation approach in a virtual environment. Biomechanic model (mannequin) of the EMT had been simulated and analyzed by using LBA and OWAS method. The mannequin was given an improvement based on ergonomic principle of manual lifting task and then was reanalyzed. Improvement that can be used for the work system of the evacuation process conducted by EMT considering its nature situation is the work posture of personnel during the process of lifting the patient into the stretcher. The technique that can be used is the proper lifting techniques. The results of this research can be used as a recommendation to the work system of the EMT.
