Leisure, Health and Safety
Each job will cause tension (stresses) and stresses (strains) that affect the skills and work attitudes (Silalahi and Bennett, 1995). It will cause the low level of comfort, health, and safety. The main purpose of the re-design is that the workers can do its work with the comfortable, healthy, and safe production process so that it can run efficiently and effectively. Furthermore the quality and quantity of production will be increased so that it can increase the economic value added for the industry concerned. Comfort in this situation is felt by people when working or interacting with the environment. Conditions include the postures and body organs including organ in the normal position in accordance with human limitations and capabilities of the workers. This means that the organs of workers do not get pressure, does not bear the burden, and does not receive excessive papran of work procedures, work environment and their work (Apple, 1087; Bridger, 1995; and Woodside and Kocurek, 1997). Examples include work in the proximity of raw materials, and the distance the key engine operating range is not too far from the position of sitting or standing. Tables and chairs according to the size anthropometri body, and chairs have a design that allows the body to sit with normal postures. Work loose enough room to do activities of the production process. Lighting does not dazzle, but enough to meet demand in the job. Room temperature is considered to be comfortable 20 – 25 OC, there is no source of noise, no excessive dust and no smell of sting (Pulat, 1992) The use of a robot arm machine las not meet aspects ergonomik. The size of the equipment in accordance with the engine not working postures, it can be seen from the behavior of the workers who tiptoe or bend over to adjust the condition of equipment used. Lighting, temperature and noise in the room is far from certain standards established by the National Board of Standards. Condition felt more or less comfortable with the dust and smell the sting. Arranged through the health promotion action, preventive and curative potential of disease due to workplace health and disruption caused by work factors and work environment. According to Bridger (1995) work procedures that are less efficient and the room or place of work as less ergonomic layout of the raw materials, machines, and table-chair, can cause fatigue, cramps, or pain in the muscle specific (CTDs, cumulative trauma disorder) . Exposure to certain chemicals, noise, room temperature, humidity, debudi work or vibration machines work the same or even exceeds the threshold, can cause restlessness, feeling less comfortable and more information will be one of the causes of disease due to work (Scott, 1995; Ladoi, 1998; and Zenz, 1994). Similarly, light in the room of the flashy or inadequate air circulation and a less perfect, could be one of the causes of the incidence of disease due to work. Work environment factors that were not so dominant, but can determine the succession health workers, among others, is the cleanliness, neatness, color walls, floor type, the type of ceiling space, information or a promotional poster and information on using the machine work. Responsibility health will result in a decreased ability to work so that work productivity is also declining. Health include a variety of hazardous and toxic, and the source of the disease due to other work, both produced during the process and waste from the production process. Each worker must obtain a guarantee of job security and company. It is important to consider in order to improve the quietness of work. Safety-related ways to do the work, machines, devices work, materials and processing, the workplace, and environment (environmental, man, machine, methode, time and information). The aim is to prevent disability and death as a result of workplace accidents. Keyserling (1998) emphasize the primary responsibility of the business to minimize the risk of disability in a way to prevent the occurrence of workplace accidents and controlling the sources of risk exposure in the workplace.
Leisure, health and safety are related to the ergonomic approach. Ergonomik term comes from the language ergon (work) and Nomos (law of nature) and can be defined as a quiet study aspects of the human environment in the work system to be reviewed daris terms of anatomy, physiology, psychology, engineering, management and design (planning). Ergonomik related to optimization, efficiency, and ability to apply information related to the limitations, abilities, and human capacity for create a design tasks (human task), machine, system, the workplace and work environment, where human comfort can be guaranteed, health, safety and efficiency (Bhattacharya, 1996). Ergonomik needed in the studies on which the human system, working facilities, and the environment interact with each other that is the main goal of the atmosphere to adjust human beings. Ergonomik is also known as Human Factors (Nurmianto Eko, 1996).
Ergonomik focus of attention is closely associated with the human aspects in planning man-made objects and the work environment. Ergonomik approach to research on the limited human ability both physically and systematically. Ergonomik approach and utilize this information for the purpose can improve efficiency, effectiveness and productivity of work, and the system can create a work environment and a safe, comfortable and healthy. The purpose and objective of the effort ergonomik is working to improve human performance, such as adding speed work, accuracy, health and comfort while working to reduce energy work and reduce the excessive fatigue that comes too fast. In addition, expected to improve efficiency in human resources and minimize damage to equipment due to workplace accidents.
Implementation ergonomik activity in general is designed building (design) or re-design (re-design). This can include hardware such as work tools (tools), work benches (benches), the system control (controls), office equipment work (work holders), and others. implementation ergonomik factors create a design back to work in the framework of the implementation of process automation of production, can be easily applied without causing damage to the environment, hazard risks in the use of accident, comfortable and healthy (hers oriented).
