Pulmonary Tuberculosis (TB) is a contagious infectious disease caused by the bacterium Mycobacterium tuberculosis through droplets from patients diagnosed with TB. Based on the Global TB Report 2024, WHO reported that Indonesia ranks second in the world, where 81% of cases were confirmed and 90% of them had received treatment, where there was an increase in the number of cases compared to 2023 with 77% of confirmed cases and 88% of them received treatment. The increase in the number of pulmonary TB cases is inseparable from factors that determine the transmission of M. tb such as the concentration of organisms in the air related to ventilation and the length of time a person inhales contaminated air. To determine the relationship between ventilation conditions and home lighting to the incidence of pulmonary TB in the working area of ​​the Glugur Darat Health Center in 2025 This study is an analytical study with a cross-sectional study design. Sample selection used the consecutive sampling method with 56 patients who met the inclusion criteria. Of the 56 people who met the criteria, 30 people (53.6%) were pulmonary TB sufferers and 26 people (46.4%) were not pulmonary TB sufferers. The majority of respondents were male (38 people) and the highest number was found in the 18-59 age range (48 people) (85.7%). Regarding ventilation conditions, 34 people (60.7%) did not meet adequate ventilation requirements, and 29 homes (51.8%) did not meet adequate lighting requirements. There was a relationship between ventilation conditions and the incidence of pulmonary tuberculosis in the Glugur Darat Community Health Center work area, but there was no relationship between home lighting and the incidence of pulmonary tuberculosis in the Glugur Darat Community Health Center work area.

The purpose of this research is to produce tangible results in providing comfort or convenience in turning on or off the night life at home everyday, especially for people who forget to turn off the lights. The method used in making microcontroller-based home lighting control using an android smartphone is. This research method consists of several stages, analysis methods, design methods, implementation testing methods, and maintenance. The results achieved are improving the aspects of comfort and convenience for agencies, where this series of tools works after bluetooth devices are available on android smartphones. connected to a bluetooth module which is connected to the Arduino microcontroller. Basically, the principle of using this tool is that users must be able to operate a smartphone based on the Android operating system. The conclusion of this research is that the Arduino-based light control device using bluetooth can fulfill its function to control the lights properly and the device is designed to be minimalist and safety so it is safe to use.
