Abstract

Community service activities organized by the Faculty of Engineering at Unika Atma Jaya with the theme of providing basic electronics skills to junior high schools (SMP) at SMP Kristen Harapan untuk Bangsa Cilincing, North Jakarta have been held 2 (two) times. This program received a positive response from teachers and students in grade 1 of junior high school. In previous activities, teachers had not been involved in the process, so that program continuity could not be implemented routinely in schools. Therefore, in this PKM activity, basic electronics training will be focused on teachers. The aim of this training is to provide training for teachers so that in the future SMP Kristen Harapan untuk Bangsa can organize extracurricular programs regarding the basics of electronics. In this training, teachers receive training using the TinkerCad simulation program, which is a simulation program for assembling electronic circuits. The teachers also had the opportunity to assemble a series of simulation results of running lights and microcontrollers on the project board. Based on the feedback, teachers from different educational backgrounds were able to assemble and run a series of simulation results. It is hoped that in the future teachers can provide this training to their students.

Abstract

Pada generator magnet permanen, semakin besar flux magnet akan semakin besar back-emf. Namun semakin tinggi flux magnet akan semakin tinggi rugi daya pada inti stator dan inti sehingga akan meningkatkan suhu kerja generator.  Pada inti rotor, salah satu cara mengurangi rugi daya adalah dengan mengurangi volume rotor yang dialiri flux magnet. Studi ini membahas pengaruh penambahan lubang pada inti rotor terhadap flux magnet pada celah udara.  Metode yang digunakan adalah simulasi magnetic menggunakan software FEMM 4.2. Simulasi diawali dengan kombinasi ketebalan magnet 1-5 mm dengan jarak antar magnet pada rotor 1 mm dan celah udara 3 mm untuk membuktikan relasi antara ketebalan magnet dan flux magnet di celah udara. Ketebalan magnet 5 mm dengan rapat fluks tertinggi kemudian dikombinasikan dengan penambahan lubang identik pada rotor sebanyak 1-8 buah.  Flux magnet di celah udara diamati.  Hasilnya : (i) semakin besar tebal magnet semakin tinggi flux magnet pada celah udara, (ii) penambahan lubang pada inti rotor tidak menurunkan flux magnet di celah udara, bahkan semakin banyak lubang identik pada inti stator cenderung meningkatkan nilai flux magnet di celah udara.

Abstract

The right schedule for taking medication according to the frequency given by the doctor is one of the success factors of the treatment process. However, due to the patient's busy schedule and physical limitations of the patient as well as in the case of the elderly who are unable to carry out their normal activities, it is necessary to remind them to take medication regularly according to the doctor's prescription. The research method uses the waterfall model, which was developed by Pressman. The alarm system in this medicine storage box is designed to dispense medicine and sound an alarm at a predetermined time. Users only need to enter the medicine to be consumed by setting the frequency and time of the alarm. This system uses a real-time clock connected to the Arduino Uno microcontroller. The system data input comes from the matrix keypad to enter the alarm time and the light sensor to detect the presence of medicine. The output of the microcontroller controls the buzzer as an alarm and the solenoid valve to open the box containing the medicine to be taken at a pre-programmed time. From the test results obtained that the device can dispense medicine according to the frequency and time of the alarm that has been determined by the user. Keywords: alarm; medicine storage box; Arduino Uno; real time clock Abstrak Jadwal minum obat yang tepat sesuai frekuensi yang diberikan dokter merupakan salah satu faktor keberhasilan dari proses pengobatan. Namun karena kesibukan dan keterbatasan fisik pasien maupun pada kasus lansia yang sudah tidak dapat beraktivitas secara normal, diperlukan pengingat waktu minum obat secara rutin sesuai resep dokter. Metode penelitian menggunakan model waterfall, yang dikembangkan oleh Pressman. Sistem alarm pada kotak obat ini dirancang untuk mengeluarkan obat dan membunyikan alarm pada waktu yang telah ditentukan.  Pengguna hanya perlu memasukkan obat yang akan dikonsumsi dengan mengatur frekuensi dan waktu alarm. Sistem ini menggunakan real time clock yang terhubung ke mikrokontroler Arduino Uno. Masukan data sistem berasal dari keypad matrix untuk memasukkan waktu alarm dan sensor cahaya untuk mendeteksi adanya obat. Keluaran mikrokontroler mengendalikan buzzer sebagai alarm dan katup solenoida untuk membuka kotak yang berisi obat yang akan diminum pada waktu yang telah diprogram sebelumnya. Dari hasil pengujian diperoleh bahwa alat dapat mengeluarkan obat sesuai dengan frekuensi dan waktu alarm yang telah ditentukan oleh pengguna.

Abstract

The Electrical Design Laboratory is a facility where lecturers and students carry out various experiments, research and developments related to electricity. Monitoring electrical power can be a very smart move to manage expenses and also help reduce environmental impact. Electrical power usage that is not directly monitored during peak loads will result in excessive power usage. Therefore, MCB trips often occur in electrical design laboratories on switchboards with high loads, so the ability to monitor electric current usage is required. The PowerTag system was introduced to meet this tracking need for controlling Air Conditioning, Incandescent Lamps, Heaters, Dispancers and Vacuum Cleaner loads. The system is connected to the load to determine the magnitude of electrical parameters such as power, voltage, current, power factor, and then these parameters will be sent via the Zigbee communication protocol to the Concentrator. The concentrator receives data from PowerTag and then forwards it to a local server using the Modbus TCP/IP communication protocol to then be processed to the HMI for presenting data resulting from monitoring the system. The aim of this research is to design a tool that can detect current, voltage, power, power factor and frequency in real time. The research results show that the current flowing in the neutral conductor is 4.46 A and 6.69 A

Abstract

Banyaknya pengguna sepeda motor yang ada tentu tidak lepas dari jumlah kecelakaan sepeda motor dan pencurian sepeda motor. Salah satu penyebab kecelakaan sepeda motor yaitu kekurangan tekanan angin pada ban. Hal ini dapat terjadi karena repotnya mengukur tekanan angin sendiri. Oleh karenanya dibuatlah sebuah monitoring system yaitu alat untuk mengukur tekanan angin pada ban dan menampilkannya pada aplikasi smartphone. Dalam aplikasi juga terdapat layar kedua untuk melacak lokasi sepeda motor untuk mengatasi terjadinya pencurian. Alat ini direalisasikan menggunakan mikrokontroler arduino nano untuk memproses data dari sensor tekanan untuk mengukur tekanan angin dan pada arduino yang berbeda memproses modul Global Positioning System untuk melacak lokasi sepeda motor. Hasil pemrosesan arduino ditampilkan pada aplikasi yang terbagi menjadi dua, yaitu layar pertama untuk nilai tekanan angin ban dan layar kedua untuk lokasi sepeda motor. Pada layar pertama bila tekanan angin ban lebih rendah dari nilai threshold, maka akan memberikan peringatan kepada pengguna. Pada layar kedua lokasi sepeda motor ditampilkan secara visual melalui google maps.

Abstract. Road is one of the transportation infrastructure that plays an important role in supporting regional development, increasing the regional economy, facilitating the mobility of people, goods and services. For this reason, in order to support national economic activities, the Ministry of Public Works and Public Housing through the Directorate General of Highways carries out the planning and construction of several new roads on an ongoing basis. In addition, for existing roads, the Directorate General of Highways needs to carry out maintenance so that existing assets can continue to function. The threat of natural disasters and the instability of road bodies is a serious problem. This can cause damage to the road body and even the road body can be cut off suddenly, resulting in reduced road performance. One of the roads in Maybrat district, precisely in the Ayawasi – Sisu KM 273+500 section, experienced a road collapse that cut off access between districts, resulting in a stagnation of economic activity. Therefore, a landslide handling design is needed so that the road can be accessed again.The design process was carried out through several stages, including Preliminary Survey, Hydrological Survey, Geotechnical and Geological Survey, Topographic Survey, and Planning. In the planning process, the most effective and efficient design will be selected according to field conditions. Slope stability analysis using Slope/W software. Based on the results of the planning, the design of the Concrete Soil Retaining Wall with bored pile reinforcement is used as an alternative treatment because it can be done easily in the field and can overcome the problem of landslides in the area.Keywords: Safety factor; Concrete Retaining Wall; Bored Pile; Landslide; Slope-W
