Abstract

Industri dalam negeri memproduksi transformator toroid yang berfungsi sebagai penurun tegangan atau menaikan tegangan listrik. Untuk saat ini, proses pembuatannya masih banyak menggunakan mesin manual. Meskipun banyak mesin penggulung lilitan otomatis yang diproduksi luar negeri, tetapi harga mesin tersebut masih relatif mahal. Oleh karena itu, dibuat alat penggulung lilitan transformator toroid berbasis mikrokontroler ATmega328 yang dibuat dengab kualitas yang baik dengan dilengkapi fitur yang dapat mengatur jumlah lilitan, tampilan digital, sensor, dan motor yang bergerak secara otomatis dengan menggunakan sistem program Arduino. Dari hasil pengujian alat penggulung lilitan transformator toroid berbasis mikrokontroler ATmega328, didapatkan hasil yang baik dengan tingkat ketelitian sebesar 98,63%, tingkat akurasi sebesar 99,73% , dan tingkat kesalahan rata-rata sebesar 0,461%. Daya yang relatif lebih rendah sebesar 55 Watt dan biaya yang relatif lebih murah dapat menjadi keunggulan alat ini

Abstract

In its working system, the assembling machine has supporting electrical components that function as parameters: Servo motors function to push or rotate objects with high-precision control in terms of angular position, acceleration and speed, inductive proximity sensors function as parameter determinants for metal or non-metal items, PLC as a parameter process unit as well as actuator signals based on the parameters received. Based on the test data conducted on this tool and system, the following conclusions can be drawn: The measurement results of the selenoid valve using a wind regulator cannot exceed 20 bar, because the air cylinder will push very strongly if it exceeds 20 bar. The SG90 servo motor voltage obtained is different from the power supply voltage so that the error value is obtained with an average of 14.87%. The selenoid valve voltage without load is 0.4 V, then the (%) error is 16.9% and the selenoid valve voltage with load is 0.6 V then the (%) error is 25.6%. Servo motor voltage without load is 0.3 V, then error is 6.67% and servo motor voltage with load is 0.9 V, then error is 23.07%.

Abstract

The external electrostatic lightning protection system is installed to preventing, avoiding, and reducing the dangers of lightning strikes in the Indriati Boyolali Hospital which is located on Jl. Boyolali-Semarang No. KM.02, Mojosongo, Kec. Boyolali, Kab. Boyolali, Central Java 57322. This study discusses how to analyze the building's need for lightning protection, analyze the area protected by lightning protection and analyze the existing grounding system. The study began with the collection of primary data which means conducting research directly in the field and secondary data which means collecting data by taking measurements using an earth tester and calculation formulas in accordance with applicable regulations. The results of the study at Indriati Boyolali Hospital according to the PIUPP standard obtained a value of 18, this is very necessary for lightning protection, according to the NFPA 780 standard obtained a value of 28, this is very necessary for lightning protection and according to the IEC 1024-1-1 standard the level of protection with an efficiency of 95% which is in class II, this is also very necessary for lightning protection. Analysis of the protected area is 53,066 m² with a protection angle of 48.93°. Analysis of the grounding system at points A and B result 5.09 Ω and point C 26.69 Ω when the three points are connected in parallel the result is 2.33 Ω below the standard which is ≤ 5 Ω.

Abstract

The increasing number of motorcycles is one of the factors in the increase in motorcycle theft crimes, a vehicle thief usually uses his own T-shaped key to damage the mechanical system of the ignition lock on a motorcycle vehicle. This research was organized to be a solution in solving the problem of motorcycle theft by designing a motorcycle ignition control system based on IoT using NodeMCU and GPS. Based on the results of the study, it shows that the IoT-based ignition lock control system is able to work optimally in line with what is expected, namely using the Telegram application to activate the relay which makes the NO relay pin connected so that the electrical system in the ignition lock is connected and deactivates the relay which makes the NO relay pin open again so that the electrical system in the ignition lock is disconnected with a response time of ± 15 seconds and ± 16 seconds to get a notification message that the command was successfully executed, and when the relay is inactive if the SW-420 sensor detects vibration, it will immediately send a warning message notification to the Telegram application that the vehicle is in motion. The Telegram application can also find out the location of the vehicle with the help of GPS embedded in the tool that has been made
