RANCANG BANGUN SUCTION PUMP DENGAN 2 TABUNG DAN PENGATURAN TEKANAN BERBASIS PWM ARDUINO

Suction is used in the medical field to take or drain fluids out of the body. Professional use of suction can be used to remove or reduce blood in the operated area to allow the surgeon to see and work on that area. Suction is also used to remove blood that is already in the skull after intracranial bleeding. Most of the suction devices used still have a simple appearance or still have a manometer, which means that the suction pressure on the suction cannot be adjusted automatically. Therefore, the aim of this research is to design a suction pump with motor speed using PWM (Pulse Width Modulation). The method for making this tool uses an Atmega328 microcontroller as a controller, an LCD (Liquid Crystal Display) as a display of pump suction speed and suction pressure, an MPX5500DP sensor as a suction pressure reader. To control the suction speed, the L298N motor driver uses a PWM (Pulse Width Modulation) signal with a maximum result of -178 mmHg. Testing was carried out at vacuum pressure using a DPM (Digital Pressure Meter), apart from that testing was also carried out on the circuit working system. Circuit testing is needed to find out the working principle of the circuit and the tools being made. After testing and measuring the tool, the error percentage was 0.86% for the smallest result. Meanwhile, the largest error percentage is 8.5%. The allowable correction value for the suction pump pressure parameter is ± 10% of the maximum scale of the tool setting point. So from the results of this analysis the tool is suitable for use because it is still within safe tolerance limits

PERSEPSI PENUMPANG TERHADAP PENERAPAN BAGASI BERBAYAR MASKAPAI WINGS AIR DI BANDAR UDARA HAJJI HASSAN AROEBOSMAN ENDE

The purpose of this study is to ascertain how travelers view Wings Air's use of paid luggage at the Hajji Hassan Aroeboesman Ende Airport. Airlines may learn a lot from passenger impressions about the use of paid luggage, including whether aspects of the current policy require further examination. At the Hajji Hassan Aroeboesman Ende Airport, the research was carried out. The study employed a quantitative survey methodology. The population of this study consisted of all Wing Air passengers at Hajji Hassan Aroeboesman Ende Airport; the sample consisted of 100 passengers who used paid luggage.  Pearson  Product  Moment  was  used  to  assess  the  validity  of  the  questionnaire  technique in obtaining the data, as well as the validity of it using Cronbach's Alpha. In order to determine the category of passenger perception, the mean value of the test variable was calculated using descriptive analytic techniques on the gathered data.  With  a  mean  score  of  3.23,  the study's  findings demonstrated   that   passengers'   perceptions of   the   Hajji   Hassan   Aroeboesman Airport's implementation  of  paid luggage were  deemed  "Pretty  Good"  by  the  participants.  A perception is considered “Quite Good” if it is sufficient and meets user expectations. On the other hand, perceptions that are Fairly Good, Very Good, and Not Good are highly valuable for airlines to maintain review by taking into consideration consumer concerns about the airline's rules so that going forward it even better

PENGARUH PENGGUNAAN MICROSOFT EXCEL TERHADAP EFEKTIVITAS KERJA KARYAWAN DENGAN VALIDITAS DATA KEBERANGKATAN DAN KEDATANGAN PESAWAT SEBAGAI VARIABEL INTERVENING DI TERMINAL OPERASIONAL CENTER PT. ANGKASA PURA II SOEKARNO-HATTA

The effectiveness of employee work in airline companies is strongly influenced by the validity of aircraft departure and arrival data. This study found that the use of Microsoft Excel alone has no significant influence on employee work effectiveness without the validity of departure and arrival data as an intervening variable. Valid data, which is data that is accurate, detailed, and has minimal errors, plays a key role in improving employee work effectiveness. The use of Microsoft Excel becomes significant in improving work effectiveness only when the validity of departure and arrival data is considered. This is evidenced by the results of the study showing a significance value of 0.00 <0.05 and a T-test between Microsoft Excel and employee work effectiveness of 0.0448, which indicates no significance without intervening variables. However, with the validity of departure and arrival data as an intervening variable, the T-test value increases to 0.001, and the Sobel test shows a significant effect with a T-count value of 6.190 > 2.052. The coefficient of determination (R2) of 0.929 indicates that 92.9% of the variability in employee work effectiveness can be explained by the relationship between the independent and dependent variables. Thus, the validity of aircraft departure and arrival data is an important factor in maximizing employee work effectiveness through the use of Microsoft Excel at the terminal operations center of PT Angkasa Pura II Soekarno-Hatta

ANALISIS PENURUNAN JANGKAUAN PANCARAN T-DME (TERMINAL-DISTANCE MEASURING EQUIPMENT) MERK NEC NNG-1796A DI BANDARA INTERNASIONAL MINANGKABAU

Terminal Distance Measuring Equipment (T-DME) is a type of aviation navigation equipment that helps pilots provide distance information to landing location points. This T-DME is usually installed side by side with the Landing System Instrument equipment, namely Glide-Path, in this case the T-DME has the function of providing distance information, especially to the Glide Path ground station when carrying out aircraft landing procedures. To ensure that the T-DME equipment is in normal operating condition, calibration activities need to be carried out so that the T-DME equipment remains in accordance with the provisions and parameters. In this research, a problem was found with the T-DME where the beam range was reduced during the calibration process. The method that will be used in this research is a qualitative method to support the data needed in cases of problems that occur. The author analyzes the problems in this research with stages that can help resolve related problems with the aim of ensuring that the T-DME equipment can operate normally and restore the beam range of this T-DME equipment for use in the aircraft flight process safely and appropriately.Terminal Distance Measuring Equipment (T-DME) is a type of aviation navigation equipment that helps pilots provide distance information to landing location points.
