COVID-19 menyerang manusia pada akhir tahun 2019. Penyebaran COVID-19 terjadi melalui droplet/cairan yang keluar dari mulut/hidung manusia. Antisipasi penyebaran COVID-19 dilakukan dengan menerapkan pola hidup bersih dan sehat. Salah satu caranya adalah dengan mencuci tangan menggunakan hand sanitizer. Penggunaan hand sanitizer di tempat umum memungkinkan terjadinya kontak fisik antar pengguna sehingga diperlukan cara untuk mengurangi kontak fisik tersebut. Cara yang bisa diterapkan adalah dengan menggunakan hand sanitizer otomatis. Prinsip dari hand sanitizer otomatis ini adalah ketika tangan didekatkan dengan botol hand sanitizer maka secara otomatis cairan akan keluar dengan sendirinya ke telapak tangan. Berdasarkan hasil penelitian yang telah dilakukan, hand sanitizer telah berhasil dibuat dan dapat digunakan di Politeknik Negeri Batam.

Modul akuisisi data dengan menggunakan Modbus Remote Terminal Unit (RTU) telah banyak digunakan secara komersial di industri. Namun sayangnya, harga peralatan tersebut tergolong mahal. Protokol komunikasi Modbus RTU ini cukup kompleks untuk dibuat oleh pengguna awam, seperti siswa sekolah menengah vokasi dan mahasiswa. Dengan latar belakang tersebut, penelitian ini bertujuan untuk membuat modul komunikasi Modbus RTU over RS485 yang berbasiskan Arduino sehingga harga pembuatannya menjadi murah dan dapat menjadi sarana pembelajaran di sekolah menengah maupun universitas. Modul yang dibuat ini terdiri atas dua input analog dan dua input/output digital. Sinyal analog yang masuk dikondisikan terlebih dahulu dengan menggunakan signal conditioner sebelum diproses lebih lanjut oleh mikrokontroler. Hasil pengujian menggunakan Modbus Analyzer menunjukkan bahwa komunikasi Modbus RTU over RS485 pada modul yang telah dibuat ini berjalan dengan baik.

Monitoring Technology is a system with low cost and high efficiency becomes a challenge in the current era. The author makes a room monitoring system with wireless sensor network (WSN) based radio frequency GSM and SMS Alert. This system consists of two pieces of slave nodes and one master node. Master node and slave nodes using XBee modules as communications equipment. Each slave node consists of a DHT11 sensor to measure the room temperature and humidity, light sensor light dependent resistor (LDR) for measuring the intensity of light, the voltage sensor to measure the voltage source tools and PIR sensor for detecting movement of people in the room. All data sent to each slave node to the master node is processed and displayed. Then when the system is operating in a state of active monitoring, when the movement is detected, the master node will send SMS alerts to the user using a GSM modem wavecom module. Room monitoring results with these systems in accordance with the design, room condition information generated quite accurate with an average error of measurement is not more than 2%. SMS alerts precisely and quickly accepted by the user as soon as movement is detected in the room.

Its necessary a technology or advanced device that can observe atmospheric data and send it to an earth station (ground segment). Data of information on air pressure, temperature, humidity, and wind speed are ordinarily needed by the Meteorological, Climatological and Geophysical Agency (BMKG) in weather forecasts. To be able to receive atmospheric data sent by the payload, the ground segment requires a receiver equipped with an antenna that has a big gain. The receiver is a transmission device which is equipped by an antenna. Double Biquad antenna is one of antenna with a big gain. Utilizing of the excellence specs of Double Biquad antenna, the author pick this antenna as a ground segment device that can support telemetry communication systems. The process of designing the Double Biquad antenna is carried out using an antenna calculator which is then simulated using 4nec2 software. The results of the antenna manufacture were tested and measured the antenna parameters such as: VSWR, impedance, radiation pattern and compared the RSSI value with Monopole on 3DR. The results show that the optimum frequency is 449.056 MHz with a VSWR of 1.33 which still meets the criteria of 1 ≤ VSWR ≤ 2. The value of the RSSI range on the Double Biquad antenna, 145 - 220, is better then comparison antenna. Coupled with the reflector which also strengthens the reception of power on the antenna. So this antenna is feasible to be used as a communication antenna in the ground segment which working on 433 MHz. Dibutuhkan sebuah teknologi yang dapat melakukan pengamatan data atmosfer dan mengirimkannya ke stasiun bumi (ground segment), tentunya dibutuhkan suatu perangkat khusus yang dapat melakukan hal tersebut. Data berupa informasi tekanan udara, temperatur, kelembaban, dan kecepatan arah angin biasanya dibutuhkan oleh Badan Meteorologi, Klimatologi, dan Geofisika (BMKG) dalam melakukan prakiraan cuaca. Untuk dapat menerima data atmosfer yang dikirim oleh payload, pada ground segment dibutuhkan suatu receiver yang dilengkapi dengan antena yang memiliki gain besar. Receiver tersebut adalah alat transmisi yang sering disebut dengan antena. Salah satu antena dengan gain yang besar adalah antena Double Biquad. Dengan memanfaatkan kelebihan yang dimiliki oleh antena Double Biquad penulis memilih antena ini sebagai perangkat ground segment yang dapat mendukung sistem komunikasi telemetri. Proses perancanagan antena Double Biquad dilakukan menggunakan antena calculator yang kemudian disimulasikan meggunakan software 4nec2. Hasil pembuatan antena diujicobakan dan dilakukan pengukuran beberapa parameter antena seperti: VSWR, impendansi, pola radiasi dan membandingkan nilai RSSI dengan antena pembanding (Monopole pada 3DR). Hasil pengujian menunjukkan nilai frekuensi optimum yang didapat sebesar 449,056 MHz dengan VSWR sebesar 1,33 dimana masih memenuhi kriteria 1 ≤ VSWR ≤ 2. Nilai rentang RSSI pada antena Double Biquad, 145 – 220, lebih baik jika dibandingkan dengan antena pembanding. Ditambah dengan adanya reflektor yang turut memperkuat penerimaan daya pada antena. Sehingga antena ini layak untuk digunakan sebagai antena komunikasi di ground segment pada frekuensi kerja 433 MHz.

In 2018, Batam State Polytechnic has carried out community service in the village of Pasir Panjang, Rempang Island. Pasir Panjang village is one of the villages that is still not electrified by the local electricity company. The village also experiences difficulties in providing clean water because of its location on the coast. Therefore, the dedication of the Department of Electrical Engineering at the State Polytechnic of Batam in the form of grants and installation of water pumps for public facility with an independent power source from a 100WP solar cell. The problem arises when after carrying out the installation, the water pump cannot pump water properly. In the following year, the service was continued by making improvements to the electrical installation system. Starting from the analysis of the causes of system failure to repair. From the analysis and observation, it is known that the cause of the pump not working properly is due to a decrease in voltage because the Rs value in the solar cell system is quite large. By changing the cable size for current distribution, this problem can be resolved.

Object mapping based on location tracking methods has been widely used in various types of applications. Most tracking systems recently use existing technology and infrastructure such as satellite, cellular and wireless (RF) technology. These existing technologies are high-cost technology that needs authorized permission to be integrated to the novel technology. This research proposed a cheap point to point device technology to track a location of a transceiver using GPS in a portable infrastructure using Line of sight radio communication. The tracking system design is connected to the IoT system in order to be more accessible. The proposed system using GPS as an identifier of the transceiver coordinate location and 433MHz radio module as media communication between transmitter and receiver. The use of a 433MHz radio frequency module which is free-license adds value to the system so that it will be easily accessed. The design of portable and internet-based devices also gives a positive value in which the system does not have to depend on existing infrastructure and the system can also be reached even if it is placed in remote areas. The system test results show that the system can be well accessed up to a distance of 6.8 km.
