Abstract

Purpose – The aim of this research is to determine (1) the influence of positive psychology on employee work motivation; (2) the influence of leadership on employee work motivation. In this study, a literature review method is employed for research. Design/methodology/approach – In this research, the systematic literature review (SLR) method is employed, which is utilized to search for national and international literature data with reputable sources in SINTA and SCOPUS. Findings – The results of this compilation and analysis are used to draw conclusions regarding the influence of psychology and leadership on employee work motivation. Research limitations/implications – The conclusions drawn from this research indicate that based on the above analysis: (1) Positive psychology encourages employees to achieve targets, overcome challenges, and adapt to changing work environment situations. (2) To enhance employee performance, companies are expected to identify and develop employees' psychological capital through the provision and improvement of various resources that support the achievement of employee goals, such as competence, autonomy, feedback, mental resilience, social support, and guidance from superiors. (3) Leadership style is one of the factors that can influence motivation. (4) Leadership style is an approach used by a leader to influence the performance of subordinates. Practical implications – The conclusion of implementing a leadership style is to provide inspiration, enthusiasm, and motivation to employees in carrying out tasks assigned by the organization.

Abstract

One of the aviation navigation tools is the Instrument Landing System (ILS), which functions to provide guidance signals to aircraft in the final approach position toward the runway. The ILS consists of three components: the Localizer, Glide Path, and Marker Beacon. To ensure aviation safety and security, navigation equipment must be regularly inspected through Ground Inspection. With current technological advancements, Ground Inspection is being conducted using UAVs or drones. One of the components to be installed on the UAV is the PIR, which requires two antennas of different lengths to receive signals from the Localizer and Glide Path.In this study, a dual-band antenna was developed that combines a dipole antenna and a meander line microstrip antenna for frequencies 108-112 MHz and 328.6-335.4 MHz, using CST Studio Suite 2021 software and FR-4 substrate material. Simulation results showed good performance with a return loss value of -19.43471 dB, VSWR of 1.238951, and a bandwidth of 2 MHz at a frequency of 110.5 MHz, and a return loss value of -27.41626 dB, VSWR of 1.119686, and a bandwidth of 2.5 MHz at a frequency of 329.6 MHz.Measurement parameter values for the VHF band were a return loss of -14.1680 dB, VSWR of 1.487, and a bandwidth of 14.6 MHz. Meanwhile, for the UHF band, there was a shift in the resonance frequency to 368.5 MHz with a return loss value of -15.4202 dB, VSWR of 1.408, and a bandwidth of 11.4 MHz. In this antenna design, a dual-band combination of a dipole and a meander line microstrip antenna with dimensions of 320 mm was achieved, capable of operating in both the VHF and UHF frequency bands simultaneously. However, this antenna can only operate at the Localizer working frequency.
