Harmonics are a phenomenon that arises due to the use of non-linear loads in electric power systems. Harmonic problems in electric power systems are increasingly complex with the increasing use of non-linear equipment (for example: LED lights). In this research, harmonic measurements were carried out using a Power Analyzer measuring instrument. Measurements were taken for the Taxiway Light load on the South Runway at Soekarno Hatta Airport which uses LED lights. The measurement results show that high harmonic currents are still visible, exceeding the standard value of short circuit ratio for electrical installations of 15%. The largest harmonic currents are detected in the 3rd order with a frequency of 150 Hz (3 x 50 Hz). The percentage of current harmonics in the 3rd order reaches 108.02%, while the voltage harmonics have almost the same spectrum characteristics and occur in the odd order. The most significant voltage harmonics were detected in the 5th order, namely 5 x 50 Hz = 250 Hz with an average percentage of harmonic voltage at this frequency of 1.54%.

In aircraft maintenance, it is necessary to calculate the workload, to find out how much manpower is needed for a job. Determining manpower requirements to ensure maintenance work is carried out in an efficient manner and at a high level of quality. The Aviation Facilities Calibration Center (BBKFP) still applies a conventional approach in carrying out maintenance, with crowds without a clear manpower estimate for the work carried out by technicians. The method for calculating workload on Maintenace Phase 1 King Air B200 series is the Full Time Equivalent (FTE) method. The purpose of this research is to find out the amount of workload in Maintenance Phase 1 of the KingAir B200 series, to find out the suitability of the optimal number of manpower in Maintenance Phase 1 of the King Air B200 Series, and to find out the number of technicians that corresponds to the workload from the FTE calculations in Maintenance Phase 1 of the King Air B200 Series. The results of this research showed that 63.63% of the sections were still in the Overload condition, 9.09% were in the Underload category and 27.27% were in the Fit / Normal Category.

The development and test of electric motors on Unmanned Aerial Vehicles (UAV) requires a sophisticated and efficient approach. This research discusses the design of innovative UAV electric motor test equipment applications using Python software-based Graphic User Interface (GUI). The main objective of this application is to provide an intuitive and effective user interface to control, monitor, and test the performance of UAV electric motors. In this study, the waterfall method was used for system development. Preliminary test results show that the application is easy to use and efficient in testing UAV electric motors. It is hoped that this design will help the development of UAV technology by providing easy-to-use and reliable test equipment for researchers, technicians, and developers in the field of unmanned flight.

Rancang Bangun Sistem Pemantau Ketersediaan Sabun dan Tisu pada Toilet Bandara Berbasis IoT

2024-02-05T21:19:00+07:00

Public toilets, especially at airports, play an important role in ensuring the comfort and cleanliness of traveling passengers. The unavailability of tissue and soap in toilets is often a problem at airports. This research aims to develop a soap and tissue monitoring system in airport toilets based on the Internet of Things (IoT) using Narrowband IoT (NB-IoT) technology and the Thingsboard platform. The prototype system for monitoring the availability of airport soap and toilet tissue was successfully created using an Arduino Nano, SIM7000C and was able to communicate with the Thingsboard via the MQTT protocol, making it possible to monitor the availability of sanitation facilities in real-time. The measurement results show that the device can operate well using an IMR 18650 battery for up to 27 hours. This system is able to provide information on the level of contents of soap containers and the capacity of available tissue along with its location. This research underlines the potential of IoT technology in overcoming the problem of unavailability of soap and tissue, aimed at increasing user comfort and maintaining the cleanliness of public facilities at airports.

Penggantian Halogen ke LED pada Runway Edge Lights Bandara Ahmad Yani Sebagai Efesiensi Energi Listrik

2024-02-06T00:32:53+07:00

Jenderal Ahmad Yani International Airport is an airport located in the West Semarang District, Semarang City. This airport has departure and arrival terminals that facilitate domestic and international flights. Ahmad Yani International Airport also has a runway (13-31) with a length of 2,560 meters. There is airport lighting system equipment whose function is to assist and serve aircraft taking off and landing so that they can operate in cloudy, cloudy weather and at night in the runway, taxiway and apron areas. One of the equipment in the airport lighting system is the runway edge lights. Currently, the runway edge lights installed at Jenderal Ahmad Yani International Airport still use halogen type lights, which require quite a large amount of electrical power and the electricity costs incurred are not small. Replacing halogen type runway edge lights with Light Emitting Diode (LED) runway edge lights as an effort to efficiently use electrical energy. In this study the author used a comparative method to determine the comparison of the efficiency of using electrical energy between the two types of LED runway edge lights and halogen runway edge lights. From the comparison data carried out, it can be concluded that replacing halogen runway edge lights with LED runway edge lights has been proven to increase the efficiency of electrical power usage over a long period of time. From the specification data, LED lamps have a longer life time, namely 56,000 hours compared to halogen lamps, which is only 1000 hours, so the savings are also greater. From power calculations, it can be seen that LED runway edge lights have more power efficiency than halogen runway edge lights. The total power of halogen runway edge lights (2 circuits) was 21,480.58 watts, while LED runway edge lights (2 circuits) decreased by 56.2% to 9,400.58 watts.
