Energi listrik merupakan salah satu kebutuhan pokok yang sangat penting dalam kehidupan manusia saat ini. Pengiriman energi listrik komersial tegangan rendah 220 volt masih menggunakan kabel listrik untuk menghantarkan listrik ke beban. Salah satu cara pengiriman atau transfer daya listrik yang terus dikembangkan sampai saat ini adalah transfer daya listrik secara nirkabel. Transfer daya listrik secara nirkabel memiliki kelebihan dibandingkan menggunakan kabel yaitu dapat meningkatkan kenyamanan dalam penggunaan peralatan listrik. Pada penelitian ini dikembangkan sistem transfer daya listrik secara nirkabel (wireless power transfer) dengan kopling induktif. Percobaan dilakukan dengan mengubah jumlah lilitan dan diameter kawat email yang bertujuan untuk mencari daya paling maksimum dan jarak paling jauh. Sumber listrik dihubungkan dengan rangkaian elektronika yang dilengkapi dengan tembaga yang telah dibentuk sebagai kumparan primer untuk transmitter dan kumparan sekunder untuk receiver yang kemudian disalurkan energi listriknya ke beban. Pada rangkaian dengan kawat email yang berdiameter 0,5 mm, jumlah lilitan 26× putaran, dan frekuensi yang digunakan 470KHz diperoleh efisiensi daya yang ditransfer pada jarak 1 cm sekitar 1,51%. Hasil dari percobaan tersebut dapat menyalakan lampu LED 1 Watt.

Robot mobile otonom (autonomous mobile robot, AMR) banyak digunakan baik di industri maupun lingkungan rumah tangga. Robot jenis ini mempunyai kemampuan bergerak menuju tempat tertentu secara otomatis. Penggunaan GPS pada tempat tertutup dan area terbatas belum dapat memenuhi kebutuhan karena keterbatasan resolusi GPS. Pada penelitian ini dikembangkan robot mobile yang mampu menuju titik tertentu dengan memanfaatkan sensor rotary encoder dan metode odometry. Koordinat tujuan diberikan ke robot dan kemudian secara otomatis robot bergerak ke arah titik koordinat tujuan. Pengujian dilakukan dengan memberikan tujuan dengan jarak berbeda yaitu 60 cm, 100 cm, 150 cm, 200 cm, dan 250 cm. Rata-rata galat perhitungan odometry yang dihitung pada jarak tersebut adalah sebesar 0.5 cm, 2.63 cm, 1.65 cm, dan 1.1 cm. Pada pengukuran secara riil didapatkan galat sebesar 7cm, 13cm, 10cm, dan 20 cm. Pengujian rute langsung mempunyai nilai galat yang paling kecil dibanding pengujian rute 1 dan rute 2 yaitu 0,11 cm untuk tujuan x dan 0,25 cm untuk tujuan y. Pada pengukuran posisi riil mempunyai galat x = 3 cm dan y = 2 cm.

Transportation is currently an unavoidable necessity. However, the COVID-19 pandemic has impacted all lines of industry, including the Indonesian aviation transportation industry. Technology is one of the solutions to deal with these problems. The monitoring system of masked face recognition and body temperature detection for the check-in process of passengers at the airport is aimed to be developed in this research. The contribution of this research is that the system can distinguish the type of face mask used. Therefore, this monitoring system classified only medical masks and N95/KN95 respirator masks as ‘Good Masked’. IP camera and thermal camera are used to identify a masked face and body temperature, respectively. The sensor fusion method was used for decision-making on passengers whether they can be departed or not. The decision was taken based on the measured body temperature, the use of standardized face masks, and the face recognition of the airport passengers. Convolutional neural network (CNN) method was used for face and face mask recognition. The CNN model training was conducted four times according to the four proposed scenarios. The CNN model that has been trained can distinguish a masked face and a face without a mask. The best results were obtained in the fourth scenario with the comparison of the training dataset to the testing dataset was 9:1 and the epoch was 500 times. The basic deep learning model used for face detection was the single shot multibox detector (SSD) using the ResNet-10 architecture. Meanwhile, the CNN method with the MobileNetV2 architecture was used to detect the use of masks. The accuracy of the CNN model for face recognition and mask recognition was 100%. All check-in monitoring and verification process data were displayed on the web application which was built on the localhost.

The problem at the current Vocational High School that often arises is the unavailability of the Supervisory Control And Data Acquisition (SCADA) practicum module, to control AC Motor which can also be monitored online (IoT support) to support industry 4.0. The following solutions: (1). The developed module must be remotely controlled with industry standards; (2). The method used during the practicum is the problem-based-learning (PBL) method. To implement the above problem, a PLC that support SCADA and IoT (MQTT) was chosen. To introduce SCADA and IoT to students, we learned how to operating a simple industry-standard SCADA software and IoT (Ubidots). Post-training from the results of the questionnaire for vocational students, it was seen an average increase in knowledge of 56% compared to before training, a min 42% increase in PBL understanding, and a max 64% increase in knowledge of "Wonderware Intouch" as one of the Industry Standard SCADA

Airline ticket reservations can be completed via ticket counters or online. To reduce passenger data redundancy, Single Identity (SI) may be required to input passenger data. In Indonesia, SI is utilised in identity cards using Near Field Communication (NFC), called electronic Kartu Tanda Penduduk (e-KTP). However, the use of e-KTP is not optimal yet because it is still used in the same way as the conventional one. Data input using SI can be done by tapping the e-KTP on a NFC-enabled machine, and the user is required to select the passengers’ names. The process of data input may be simplified, resulting in a higher transaction speed. This research result demonstrated that there was a slight difference of the time required between the two methods for ticket reservations. The time efficiency using SI through ticket counters was 48%, while the online reservation using SI was 45%. Further research may implement the validation methods, such as using PIN or fingerprint.

Accidents due to cross the lane (lane departure crash) of achieving 19% of all accidents. These accidents mostly caused because the driver is not concentrating or dozing. A device that can help the driver so that the vehicle does not exit lanes known as Active Lane Keeping Assist (ALKA). ALKA is a subsystem of Advanced Driver Assistance System (ADAS) and is now used in several brands of cars namely Audi, BMW, and Ford. ALKA useful to help the driver, especially on roads with monotonous situations such as toll roads. This paper presents the development of fuzzy logic-based algorithm for ALKA. A battery toy car is used as a hardware simulation to test the algorithm in real time situation. The test results at three different speeds are slow, medium, and high indicate that the algorithm can work according to design.

An increase in transactions in airports is in line with a growing number of airline passengers, thus, a system which can enhance the service may be required. One of the concerns related to airline services is the long time for transactions due to the time required for each transaction and the number of transactions for each passenger. One of the transactions which require long time is the check-in process. In addition, the conventional check-in process also requires paper which its use is rapidly rising due to the increasing number of passengers. Hence, an NFC (Near Field Communication)-based system can be applied to accelerate transactions and to reduce the use of paper. Transactions in airports require several documents including booking reference and passengers’ identity cards, and both of which can be digitally stored in an NFC device. This study revealed that the implementation of SI could accommodate the check-in process in airports and decrease the redudancy of passenger data.

Proses pembersihan kotoran pada kandang ayam seringkali dilakukan secara konvensional oleh peternak ayam. Peternak melakukan pembersihan kandang ayam dengan cara manual dengan waktu yang tidak tentu. Peternak harus membuang dan membersihkan kotoran tersebut secara langsung dengan menggunakan tangannya. Proses ini tentunya membutuhkan waktu yang cukup lama dan melelahkan. Pada alat ini dibuat sistem penjadwalan proses pembersih kotoran, agar lantai kandang selalu bersih. Pembersihan kotoran kandang ayam akan lebih efektif dengan menggunakan alat mekanik yang dikontrol oleh peralatan elektronik. Komputerisasi diterapkan agar pemberian makanan dapat terjadwal dengan baik. Sistem Pembersih Kotoran Kandang Ayam Otomatis Berbasis Mikrokontroler merupakan alat kontrol yang mampu membersihkan kotoran ayam secara otomatis sesuai jadwal yang telah ditentukan. Pembuatan alat ini menggunakan Real Time Clock (RTC) untuk mengatur jadwal pembersihan dan Arduino sebagai pusat pengendali sistem yang dapat memproses data sinyal perintah untuk mengaktifkan output motor DC dan swiper. Motor DC akan menggerakkan swiper secara horizontal sehingga kotoran yang ada pada papan penampung kotoran akan terdorong keluar secara otomatis. Liquid Crystal Display (LCD) akan menampilkan jadwal dilakukannya pembersihan kandang ayam secara berkala. Peternak cukup mengatur waktu penjadwalan terlebih dahulu agar Sistem Pembersih Kotoran Kandang Ayam Otomatis Berbasis Mikrokontroler ini dapat berjalan sesuai fungsinya. Para peternak akan lebih mudah dalam membersihkan kotoran pada kandang ayam karena anggota tubuh tidak perlu bersentuhan langsung dengan kotoran tersebut. Pengujian komponen seperti Real Time Clock (RTC), driver motor, limit switch, motor DC, Liquid Crytal Display (LCD) dilakukan agar didapat keberhasilan alat 100%.
