Abstract

ABSTRAKAda kebutuhan untuk peningkatan kualitas kontrol pengecekan akurasi warna bumper yang diproduksi di PT. Sugity Creatives. Kebutuhan ini disebabkan oleh berbagai pekerjaan repetitif, tidak efisien, dan relatif lama. Sesuai pengamatan, pengecekan membutuhkan waktu 45 detik, validasi data manual selama 15 detik dan pencatatan di kertas selama 60 detik. Sehingga total proses adalah 120 detik. Di artikel ini, kami mengusulkan sebuah prototipe menggunakan Konica Minolta CR400 chromameter. Prototipe ini terdiri dari dua komponen utama yaitu Raspberry Pi-4 sebagai pengontrol dan penyimpan data, dan sensor spektrometri AS7341 untuk mengukur spektrum bumper setelah selesai dilakukan pengecatan. Berdasarkan hasil pengujian, prototipe mampu mereduksi waktu inspeksi kualitas dari 120 detik menjadi 40 detik, termasuk pengukuran, validasi warna, dan juga pencatatan di spreadsheet. Validasi juga memiliki akurasi 100% sesuai dengan hasil validasi chromameter CR400 setelah prototipe dikalibrasi dengan sampel bagus dan reject. Namun, risiko kesalahan manusia selama perekaman data menyebabkan kesalahan validasi mungkin tidak dapat dihindari.Kata kunci: Raspberry Pi-4, AS7341, Chromameter, Spektrometri, Sensor ABSTRACTThere is a need to improve the quality control process efficiency for bumper color accuracy checking at Sugity Creative Companies. This need caused by several repetitives, inefficient, and relatively working time. As we observed, there is 45 seconds for checking process, 15 seconds for manual validation, and 60 seconds for data writing on paper. Thus, total processing time is 120 seconds. In this paper, we propose an improvement through a prototype using Konica Minolta CR400 chromameter. This prototype consists of two main components, namely Raspberry Pi-4 as controller and storage, and AS7341 spectrometry sensor for measuring the spectrum of the bumper color after being painted. According to our experimental result, prototype can reduce the inspection quality time from 120 to 40 seconds over the measurement, color validation, and data recording in the spreadsheet. Validation also has 100% accuracy compared to the CR400 chromameter after it is calibrated to the good and rejected samples. Moreover, the human error risk during the data recording caused the validation error is might inevitable.Keyword: Raspberry Pi-4, AS7341, Chromameter, Spectrometry, Sensor

Abstract

One of PT PLN ULP Cikarang Kota's commitments is to maintain the quality level of electricity services to maintain reliability and ensure the sustainability of electrical energy distribution. Maintenance of distribution transformers is an important key in making this happen. The effectiveness of using distribution transformers is 80% of the total capacity to prevent interference. Currently there is no tool available that can detect overload and record peak load times. This research realizes real-time monitoring of distribution substations in the PT PLN ULP Cikarang Kota area using the PZEM 004T sensor and IoT-based. The PZEM 004T sensor sends the reading results to the ESP32 microcontroller to be processed and sent to the ThingSpeak page. The reading results become material for analyzing usage patterns and the basis for making decisions on measures to prevent distribution transformer disturbances. The research was conducted at three distribution substations with residential, industrial, and a combination of residential and industrial customer types. The research results showed that the voltage at the home customer substation was normal and the purely industrial customer substation as well as the industrial and home customer substation experienced over voltage of 0.6% and 1.5%. The loading of distribution substations for industrial and home customers experienced an overload of 147% and the loading of all types of substations experienced unbalance with the highest imbalance of 77% at purely industrial customer substations.

Abstract

Soldier safety in modern military operations demands weapons systems capable of safe and precise This study presents the reactivation of a previously non-functional Remote Controlled Weapon Station (RCWS) by implementing a Proportional Control (P-control) system using the Teensy 3.5 microcontroller to regulate motor movement on the azimuth and elevation axes. The RCWS system was developed using a distributed multi-microcontroller architecture, in which the Teensy 3.5 serves as the main controller connected to the Arduino Mega 2560 Pro for joystick management and the Arduino Nano for reading the 1024 PPR rotary encoder. The setpoint values were obtained from the joystick, while the actual position was measured by the rotary encoder to calculate the error and generate a proportional PWM control signal. Experimental results indicate that a larger error between the setpoint and actual position produces a higher PWM signal, enabling the system to deliver linear, stable, and precise motor responses. Furthermore, the implementation of limit control on the elevation axis (420 ≤ θ₂ ≤ 600) effectively prevents excessive movement and protects the mechanical structure. Overall, the reactivated RCWS operates in real-time with stable serial communication, and proven reliability, offering potential for further development through the integration of PID control, fuzzy logic, or computer vision tracking to enhance the performance of remote weapon control systems. Abstrak Keselamatan prajurit dalam operasi militer modern menuntut sistem persenjataan yang mampu beroperasi secara aman dan presisi. Penelitian ini membahas reaktivasi sistem Remote Controlled Weapon Station (RCWS) yang sebelumnya tidak berfungsi, dengan fokus pada penerapan kontrol proporsional (P-control) berbasis mikrokontroler Teensy 3.5 untuk mengatur pergerakan motor pada sumbu azimut dan elevasi. Sistem RCWS dirancang menggunakan arsitektur terdistribusi berbasis multi mikrokontroler, di mana Teensy 3.5 berperan sebagai pengendali utama yang terhubung dengan Arduino Mega 2560 Pro sebagai pengelola joystick dan Arduino Nano sebagai pembaca rotary encoder 1024 PPR. Nilai setpoint diperoleh dari joystick, sedangkan posisi aktual dibaca oleh rotary encoder untuk menghitung error dan menghasilkan sinyal kendali PWM secara proporsional. Hasil pengujian menunjukkan bahwa semakin besar error antara setpoint dan posisi aktual, semakin besar pula sinyal PWM yang dihasilkan, sehingga sistem mampu memberikan respon motor yang linier, stabil, dan presisi. Penerapan mekanisme limit control pada sumbu elevasi (420 ≤ θ₂ ≤ 600) berhasil mencegah pergerakan berlebih dan menjaga keamanan mekanik sistem. Secara keseluruhan, sistem RCWS yang direaktivasi berhasil beroperasi secara real-time dengan komunikasi serial yang stabil, serta dapat dikembangkan lebih lanjut menggunakan metode PID control, fuzzy logic, atau computer vision tracking untuk meningkatkan performa sistem kendali senjata jarak jauh
