"The purpose of this paper is to evaluate the ergonomics aspects of the first prototype of a folding bike designed by the Department of Mechanical Engineering, University of Indonesia (DME UI) in a virtual environment. Posture Evaluation Index (PEI) is used as an analysis approach that integrates the results of three methods: Low Back Analysis (LBA), Ovako Working Posture Analysis System (OWAS), and Rapid Upper Limb Assessment (RULA). The determine the optimal design configuration of a folding bicycle based from an ergonomics perspective. For male and female riders, the optimal configuration is obtained when the height of the handlebar is 32 cm and the height of the saddle is 83 cm. This study proved that a virtual environment could strengthen the ergonomics evaluation, especially in posture condition exploration."

"The prominent issue of the mismatches of children’s body dimensions with school furniture has made people realize the essential factors of providing ergonomic furniture. By evaluating rural and urban areas, school furniture can be designed for both areas based on their anthropometrics, thereby combating mismatches. This quantitative study focused on four regions in Malaysia. A total sample of 2,400 primary school children from seven to eleven years old from both rural and urban schools was evaluated. Six anthropometric aspects were measured: stature, subscapular height, shoulder breadth, hip width, buttock popliteal length, and popliteal height. The measurements were evaluated using SPSS, with which T-tests were performed, to evaluate the anthropometric differences between each province. Each region showed different results when its rural and urban areas were compared. This reveals that anthropometrics are different in certain areas, even when they are in the same country. The importance of knowing such matters will help to ease the sizing of products (such as furniture) based on location, hence, making ergonomic products possible."

"Penelitian ini membahas evaluasi disain ergonomi pemicu atau yang disebut dengan trigger senjata api dengan jenis pistol terhadap penggunaan yang digunakan sebagai latihan menembak prajurit TNI. Tujuan penelitian ini adalah untuk mengetahui apakah penekanan mekanis pada senjata terlalu berat atau terlalu ringan terhadap tenaga yang dikeluarkan oleh jari telunjuk prajurit TNI. Beberapa analisis dilakukan berupa perhitungan mekanika pegas yang berfungsi sebagai momen puntir terhadap arah gaya yang berlawanan dengan arah penekanan jari telunjuk. Analisa lainnya berupa gerakan biomekanika jari telunjuk berupa perubahan sudut pada sendi – sendi yang ada pada jari telunjuk ketika melakukan tahapan penekenan pemicu pistol. Dari hasil analisis didapat bahwa hasil perhitungan mekanis berdasarkan dimensi yang ada pada pemicu berupa besarnya tenaga yang diperlukan untuk menekan pemicu pistol lebih kecil dengan perbandingan data tekan jari telunjuk prajurit TNI yang diperoleh dengan handgrip Dynamometer. Dari hasil analisa biomekanika jari telunjuk menunjukan posisi yang nyaman ketika melakukan tahapan penekanan pemicu pistol.

This study discusses the evaluation of ergonomic design of the trigger the type of firearm gun to use as soldiers shooting practice. The purpose of this study was to determine whether the mechanical strees on the finger are too heavy or too light to energy released by the soldier index finger. Several analyzes were conducted in the form of spring mechanics calculation that function as a torque in the opposite direction of the force againts the direction of the index finger presses. Biomechanics of movement in the form of changes to the index finger angle joints that exist in the index finger when the trigger gun stages of signing. From the analyisis of the results obtained mechanical calculation based in the dimensions that exist on the trigger in the form of magnitude of force required to depress the trigger gun is smaller by comparison of data tap forefinger soldiers obtained by handgrip dynamometer. From the analysis of the biomechanics of the index finger showed a comfortable position when doin presses the trigger pistol stages."
