Abstract

Currently, Bangraden Foods is having problems picking new employees by offering numerous criteria to identify the applicant's abilities and personality, the results are typically recorded and must be compared to make judgments, which takes a long time for the company. In this case, the researcher used the Tsukamoto fuzzy method to develop a decision support system because it is simple, flexible, data-tolerant, faster, and better suited for input from humans rather than robots. Based on black box testing, the web system performance results run 100% smoothly for all existing functions. Testing data on 5 new employee candidates obtained a system value difference of 0.001-0.02 with 100% data accuracy, and the system recognized the graduation of two prospective workers with a decision of 'pass' since it reached an average score of 75, according to HRD, and three candidates 'did not qualify' due to below-average grades. In addition to testing service quality, throughput of 16Kb/s is classed as 'bad', packet loss of 0.273594% as 'very good', and delay of 293ms as 'good'. As a result, Bangraden Foods management may use the system to make data processing quicker and provide advice for decisions on recruiting new personnel based on the company's needs.

Abstract

The school chemistry laboratory is a public facility for all members. So, good room security system is needed, considering the room stores hazardous chemicals are flammable. Therefore, a solution is offered to development door security system and fire monitoring in space. The purpose of this research to create and design VLC (Visible Light Communication) based door security system and to design a fire monitoring system in space. ESP32 is used as a microcontroller, temperature sensor (DS18B20), MQ-2, photodiode module, and IR Flame Infrared. The result of this research is that the maximum distance for sending passwords that can be received by the receiver is 30cm, lux <123, tilt angle 165°-180°. IR Flame Infrared can detect fire <11cm away, lux < 200. DS18B20 has sensor reading accuracy 99.97%, MQ-2 detects gas more than 300ppm. The IR Flame Infrared sensor reads the wavelength value according to the light source, namely Infrared Spectrometer. Dot have error tolerance 7ms, while dashes are 7.6ms. Overall, the system can run well. The door can be opened in two ways, using smartphone flash from outside and button from inside the room. In addition, the system can also detect fire at temperatures >50°C, wavelength <1100nm, and gases >300ppm

Abstract

In this research, the combination of the relay selection and network coding is used to measure the performance in LOS and NLOS condition over cooperative communication. The research aims are to select the best relay as assisted relay as well as to improve performance system. The research method used four nodes, two nodes as source and destination and two nodes as relays. The single relay selection is used to select best relay of several relays. Measurements are conducted by altering the positions of the relays to achieve optimal outcomes. The findings indicate that the relay with the lowest Bit Error Rate (BER) and the shortest distance is chosen. The study's outcomes, when measuring throughput, reveal that network coding throughput is 21.8% higher than that without network coding in Non-Line of Sight (NLOS) conditions. In Line of Sight (LOS) conditions, the throughput is increased by 23%.
