Radio receiver VHF A/G communication is a super heterodyne radio system, so that the radio system has a couple of blocks of the circuit and has own function. One part of the radio receiver is a Low Noise Amplifier (LNA). LNA is an important part of a radio receiver system and almost all communication equipment systems. LNA serves to strengthen the extremely weak signals captured by the antenna by adding a little bit of noise and minimize signal distortion. LNA has a specification that must be considered, such as stability, noise figure, gain, bandwidth, linearity, and dynamic range. Therefore, the LNA is very important, it is necessary to design the LNA. To increase the production of the gain can be done by designing a multistage LNA. This multistage LNA was designed using a voltage divider biasing. It was fabricated by using the Print Circuit Board with FR4 material or epoxy and using surface mounting device components. The operating point of amplifier at Ic = 5mA, VCC = 12V and VCE = 8V, requires power consumption DC by 151.2mW. This multistage LNA was simulated and the result of parameter in bandwidth show good performance and still meet the design specification. The value of parameter are stability factor in bandwidth was obtained 1.966-2.15 and noise figure 1.481-1.636dB, gain (S21) 40,168 until 43.28dB, reverse voltage gain (S12) -55.3dB until -53.53dB, output return loss (S22) below -9.4dB, at the center frequency 127.5MHz got S21=42.3dB, S11=-52.3dB, S22=-46.7dB, input VSWR=1.005 and output VSWR=1.01. This design has a good parameter and the corresponding design specifications, is expected to be applied to VHF A/G communication equipment in Sultan Bantilan Tolitoli Airport. By increasing the LNA gain can increase the sensitivity of the equipment VHF A/G communication so that air traffic controller and the pilot did not have communication problems.

Water is essential for life, but not all people can access tap water. In fact, many people use ground water, which is not measured its purity, to supply household, places of worship, public facilities, private offices, government offices, and etc. This problem was also observed on Al-Ikhwan Mosque building Jl. Masjid RT 01 RW 08 Rancagong Village, Legok District, Tangerang Regency, Banten Province. In addition, in this place the water installation was not available. Therefore, it was feasible to carry out community service activities in that location regarding to clean water supply and installation. The method of this project were (1) drilling to make wells as clean water supply, (2) Calculating the need for clean water as the basis in determining the capacity and the type of water pump, (3) building water storage (equipped with a floating sensor as a control media turn the pump on or off automatically), and (4) piping to support distribution system of clean water from well to tap. This method was expected to meet Indonesian National Standard of clean water installation system. This project was supported by lecturers / instructors as their responsibility to practice Tridharma of higher education. Cadets/students was also involved in this project so they can demonstrate their knowledge about standard of building facilities in society.

Changing times require people to be able to keep up with technological developments. One of technologies that plays a big role in changing people’s patterns and lifestyles are electronic technology. The development of electronic technology requires human resources who have competencies that are in accordance with the needs of society and industry. Based on observation survey had been done to Rancagong people, they haven’t understand about electronic too much. So that it’s worth to be done the community service at the location. Several subject matters are soldering practice, LED assembly: Seri and Parallel, LED Blinking Assembly, Assembly of Lighting Sensors Automatically and Amplifier Assembly. Implementation of community service involve lecturers/intructors as embodiment in college obligations. In addition, this activity also involves students in order to get experiences and lesson learned directly. Perubahan zaman menuntut masyarakat untuk dapat lebih mengikuti perkembangan teknologi. Salah satu teknologi yang memegang peranan sangat besar dalam mengubah pola dan gaya hidup masyarakat adalah teknologi elektronika. Berkembangnya teknologi elektronika tentunya membutuhkan sumber daya manusia yang memiliki kompetensi yang sesuai dengan kebutuhan masyarakat dan industri. Berdasarkan hasil observasi yang dilakukan terhadap masyarakat Desa Rancagong, belum banyak masyarakat yang mengerti di bidang elektronika sehingga layak untuk dilakukan kegiatan pengabdian masyarakat di lokasi tersebut. Dalam kegiatan pengabdian kepada masyarakat ini dilakukan beberapa hal yang akan menjadi solusi permasalahan yang ada di Desa Rancagong guna membuka peluang kewirausahaan, diantaranya pelatihan praktek penyolderan, perakitan rangkaian LED seri dan pararel, perakitan rangkaian blinking LED, perakitan rangkaian sensor cahaya otomatis dan merakit amplifier. Pelaksanaan kegiatan ini melibatkan dosen/instruktur sebagai wujud dharma perguruan tinggi. Selain itu kegiatan ini juga melibatkan taruna/taruni sebagai pengalaman lapangan dan media pembelajaran secara langsung.

Salah satu jenis alat navigasi penerbangan yaitu Non Directional Beacon (NDB). NDB beroperasi pada frekuensi rendah 175 KHz – 535 KHz yang berfungsi untuk memberikan informasi heading dan azimuth pesawat terhadap ground station NDB yang berada baik di dalam maupun di luar lingkungan bandara. NDB merk Nautel ND200S, baik pada konsol maupun monitoring masih bersifat analog dan manual, sehingga butuh akses langsung ke lokasi untuk melakukan monitoring parameter. Selain itu tidak terdapat alarm yang bersifat remote apabila terjadi gangguan pada peralatan. Dengan menerapkan karakteristik industri 4.0 berbasis industrial Internet of Things (IoT), maka dirancang system kendali dan pemantauan dengan mengadopsi sistem tersebut menggunakan mikrokontroller NodeMCU ESP8266. Perangkat ini terdiri dari hardware antara lain NodeMCU ESP8266, resistor, analog to digital converter ADS1115, Driver ULN2003, Stepper Motor BY28J yang di program pada software Arduino IDE dan Blynk App. Perangkat ini dapat dikendalikan dan dimonitor secara wireless selama terhubung dengan koneksi WiFi sesuai dengan program yang dibuat.

Pada pelaksanaan penelitian ini penulis dihadapkan dengan permasalahan yang terjadi pada fasilitas pengamatan penerbangan (Surveillance) yaitu Radar MSSR Mode – S Merk Indra, dimana monitor SLG atau disebut dengan (Local Management & Control Sytsem) mengindikasikan alarm pada komponen Encoder nya. Penelitian ini menggunakan metode penelitian analisis data, digunakan teknik analisis data berupa metode deskriptif. Metode ini melibatkan langkah-langkah seperti pengumpulan, penyusunan, analisis, dan interpretasi data yang diperoleh, dengan tujuan memberikan gambaran yang terperinci mengenai solusi terhadap masalah yang dihadapi. Tindakan penyelesaian pada permasalahan ini yaitu dengan cara melakukan perawatan pembersihan pada Encoder 2 karena adanya overgreasing. Overgreasing ini telah menghambat komponen elektronika di dalam Encoder 2 radar MSSR Indra untuk memproses sinyal ACP dan ARP guna informasi azimuth. Setelah dilakukan pembersihan dengan cairan contact cleaner untuk menghilangkan grease, komponen elektronika di dalamnya dapat kembali berfungsi normal, sebagaimana ditunjukkan oleh indikator normal pada monitor SLG atau SRG Radar MSSR Indra dan Pedestal Control Box Radar MSSR Indra.
