Expansion of Base Station Coverage Area Based on Sector Expansion on Lombok Island
Developing telecommunications infrastructure is vital for national advancement improving connectivity to accelerate information flow and access to public services Effective base station planning prioritizes maximizing network coverage in densely populated areas However traditional visualization methods often fall short in identifying regions with the highest population density This study addresses this gap by applying a sector expansion algorithm to select optimal base station locations within the most densely populated sectors achieving more balanced network coverage Using Indonesia s population data and administrative boundaries optimal base station locations are determined with DBSCAN and K Means clustering algorithms The network s reach is then enhanced through sector expansion to increase coverage in areas with high population density by selecting new base station locations based on the densest sector around a primary station The candidate station is positioned at a distance of three quarters of twice the radius of the primary station optimizing coverage while remaining close to existing network resources The evaluation compares population coverage before and after sector expansion assessing connectivity between base stations and distribution efficiency Results show that sector expansion increased population coverage on Lombok Island from 15 94 to 99 14 with the most populated base station covering up to 34 274 people enhancing distribution efficiency < p>

The Influence of Vocational Theory Competency Test Results on Vocational Practice Competency Test Results
This study aims to determine how much the results of the theory of vocational competency tests are related to the results of the vocational practice competency tests of TITL students at SMK Negeri 2 Manado In addition this study also analyzed how relevant the vocational theory competency test material was to the vocational practice competency test material The method used in this study is a quantitative method with 56 students as research subjects In practice the researchers found that some students already understood electric motors and some did not understand when the researchers gave practice; as a result these students did not understand when the researcher or teacher was giving theory to them When researchers teach theory and practice they often provide post tests or questions for students to work on to see whether they comprehend correctly The results showed a positive and significant effect on the results of the vocational theory competency test and the results of the vocational practice competency test In addition the results of the analysis of the relevance of the material in the theory of vocational competency tests to the results of the vocational practice competency tests were 70 in the relevant category < p>

Smart Home with Voice Control Lights Using Arduino Uno R3
The development of science and technology has positively impacted human life which has now reached the age of electric voice commands An intelligent home management system allows humans to operate their house s electrical gadgets such as lighting using simple voice commands eliminating the need to move around to switch on or off equipment When users of indoor lighting use sound waves to operate the system or turn on the lights the sound sensor sends an input signal to the microcontroller which is then processed with the microcontroller s output in the form of a voltage to turn on the load The system will function when the FC 04 sound sensor receives sound input sound code The FC 04 sound sensor can only provide a digital output signal with a value of 1 and 0 in the form of a clap which is then accumulated on Arduino with a value above 400 million by the program uploaded to be used as a 5 volt output to turn on off the lights This is because when turning on the lights from a certain distance several factors can affect it including setting the sound sensor s sensitivity and noise levels in the surrounding area < p>
