DESCRIPTION OF WORKING ENVIRONMENT SANITATION IN THE OFFICE BUILDING OF THE WARSHIP DIVISION PT PAL INDONESIA (PERSERO)

ABSTRACTSanitation is a public health effort that emphasizes mastery of various environmental factors that affect the degree of human health. Agencies that have a good and comfortable work environment will support improved performance for their employees. This study aimed to identify the description of working environment sanitation in the warship division office building at PT PAL INDONESIA (PERSERO). This research was observational. From the entire office space in the Warship Division, the five rooms with the most employees were selected for this research. The research instrument was an observation sheet with variables of building facilities, water supply, toilet, disease vector, lighting, noise, temperature, and humidity. Data analysis was performed descriptively with scoring. The results showed that four out of the five rooms (80%) that were observed had poor sanitation because they had a score of less than 75%. The results showed that the variables that were included in the criteria of lack of sanitation were toilets, lighting, temperature, and humidity. Suggestions given for the company are for building facilities, water supply, noise, and disease vector to be maintained because they are included in good sanitation criteria. Toilets, lighting, temperature, and humidity need to be fixed immediately, and reported to the officer responsible if things that can reduce the quality of office sanitation are observed. Keywords: sanitation, indoor air quality, work environment

Capacitor-less Low-Dropout Regulator for Analog Sensing using 90nm Technology

The capacitor-less-output-low-dropout (CLO-LDO) regulator proposed in this study can manage a wide variety of load currents. To offer temperature independent controlled LDO output, the LDO's 0.844V reference voltage is obtained using BGR, the optimized design is presented that provide full range stability, fast transient response. These benefits allow the proposed LDO regulator to operate over a wide range of operating circumstances, with very high current efficiency 99.99% and low voltage drop 100mV, operating using very low quiescent current of 0.02µA, at the output of regulator. The proposed regulator design is constructed in 90nm CMOS technology, the structure of the regulator is implemented using a Two-stage operational amplifier to obtain large DC gain 50dB to improve supply noise rejection, and a feedback loop, and exhibits better performance in terms of large phase margin 64.516 degrees with no load and 70.63degree full load.
