especially load to lighting for the creation for work comfort, it is necessary done saving the electricity power with method decrease the lamp point. Decrease in lamp layout is one method of saving electricity power. Method lowering the location of the point of the lamp performed in order to obtain a greater light intensity. Methods with lowering the location of the point of the lamp done to get of the lighting in the room without adding electric power 7 .

The saving of electric power by increasing the intensity of illumination do lowering the location of the point of the lamp light must done, because method lowering the location of the point of the lamp can give a good impact in the future. Shifting the location of the lights is done by providing an iron pole a few centimeters or in meters down appropriate the size of the user anthropometry.

1.2 Problem Formulation

From the above description can be made the formulation of the problem as follows :

1. What with method lowering the location of the point of the lamp can add the intensity of illumination?

2. What is the relationship of measure anthropometric the position stand the hand upward clench of

subject with high the lights?

3. Does the addition of light intensity can increase the ability of see from eye?

1.3 Benefits of Research The benefits of this research are:

1. The results of this study can be carried out on room anywhere.

2. The results research beneficial to reduce the cost burden which issued to add the intensity of

illumination.

3. The results of this research provide a picture, if there is a turn of the lights off can be done

immediately.

2. PROCEDURE RESEARCH

The material in this study was a laboratory and lamp the fluorescent 2x18 Watt as much as six (6) pieces which there are in Power Systems Laboratory, Faculty of Engineering Unibersitas Udayana. Preparing iron pipe 1\2 inci to put the fluorescent 2x18 watts. Preparing large the letters with a height of 2.2 cm and a width of 1 cm which will installed on wall on laboratory.

Method in this study is lowering the location of the point of lamp on the reseach place by providing a buffer iron on each lamp. Iron buffer will lowering the location of the point of lamp nears the point working and impacted provide illumination intensity which more light on the at the desired working point.

Procedure In this research are:

1. Measuring the intensity of light in laboratory of the Faculty of Engineering University of Udayana on

the initial conditions.

2. Recalculation ulang of many the lights.

3. Measuring the intensity of lighting to each decrease layout the lamp.

3.RESULTSANDDISCUSSION

3.1 Research Results

3.1.1 Data the size hand to workers 1) Results Calculation

Based on calculations, many lights are obtained is 12 units TL2x18 watt lamp, mounted based on rows and columns 3x4 so getting a light intensity of 250 lux with a ceiling height 3 m. The intensity of 250 lux illumination used is based on the minimum value of the intensity which the allowed. is 250-500 lux 4 .

2) Measurement results

[image:13.595.92.505.423.565.2]

Measurements were made to get the lighting intensity measurements, to compare the results of the calculation and measurement results. Measurement of light intensity 6 lights with two rows and three columns that have been attached in the laboratory TL2x18 watts equals 215.57 lux.

3.2 Discussion

3.2.1 Method of decline the location of the point Lamp.

Method of decline the location of lamp which done can an increase in the intensity of illumination. Decline is done from a distance of 15 cm, 35 cm, 45 cm 65 cm, 90 cm, and 99 cm and get the lighting intensity of 233.57 lux, 241.14 lux, 254.29 lux, 291.43 lux, 336.43 lux and 344 lux. Large the lighting intensity on each decrease in point of the lamp directly proportional to the length the decrease which is done. Decrease in light point will increase significantly the lighting intencity thus considered to be able to be applied in the workplace that require an increase in the lighting intencity.

Improve the light intencity by this method can be expected as a reference to be used as a model in the design of lighting installation without having to increase the electric power. Design an increase in the intensity of illumination should be done as a result of power shortages and assist in the implementation of energy saving 2,5 .
