Material Handling Research Results and Discussion

3.3 Machine protection

For the protection of machinery, some cases that stand out are: the use of the emergency switch 5 necessary, priority 4 , use a different switch 8 necessary, 2 priority, the switch position and movement of natural sequence 5 needs, 1 priority, the use of warning signs that easily understood and easily observed 13 necessary, 1 priority , the use of jigs and fixtures 10 necessary, 2 priority, a protective engine 10 necessary, 2 priority, care and maintenance of machinery 9 need , and safety training 8 need, 2 priority. None of the 19 indicators of the dangers of using the machine without the need to improvement. This means that the workshop should be carried out remedial measures in order to safe and secure conditions. The cases that occur, this is a picture of a lack of management workshops vocational laboratory in understanding the importance of OHS in the workshop, although still modest and limited facilities but also the safety and security aspects have not been to school culture.

3.4 Workplace design

Many SMK developed a minimal set of conditions and little by little the manager can add facilities to learn the tool, but it also has not been offset by adjustments to the comfort of work, where frequent use of tables, chairs and a roar that did not fit with certain types of work. For example, less high chairs, the table does not flat, that is not ergonomic computer desks and so on. Measures that can be done is to rearrange lay out the workshop, based on group work and readjust the table, chair and other tools so that more ergonomic. Figure 3. Good workplace design Figure 4.

3.5 Lighting

Most workshop laboratory is optimizing natural lighting, this is very aware that the use of lighting can be very costly additional electric power budget to be paid. However, in case specific work required local lighting is adequate, this can be obtained with additional local lighting and can not rely on natural light only. To determine which part needs to local lighting should be measured against the needs of the lighting and then do what the addition of lights.

3.6 Work climate

The case of work climate that often arises is due to the hot weather of the tropics, where the workshops have not been able to provide an additional tool in the form of air - suction blower, air conditioning, and maintenance procedures. If the work climate settings rely entirely on electric power would be very wasteful, and therefore should be regulated so that natural ventilation can be optimized, the layout items that allow air circulation going well, and maintain the cleanliness of the scattered dust.

3.7 Control of the dangers of noise, vibration

and electrical Besides the weather, the SMK workshop laboratory is also very familiar with the condition that noise, vibration, voltage, all of which must be controlled. This danger from the operation of machines, usually due to machines that have been long and wear out causing noises and vibrations. Therefore, care and maintenance factors machines become key to how noise and vibration can be 166
