Abstract

This research aims to develop a compressor fluid monitoring system based on the Internet of Things (IoT) for industrial weighing machines at PT. Eastern Pearl Flour Mills, supporting the implementation of Industry 4.0. The system is designed to monitor pressure, flow, and fluid temperature in real-time, enhancing the efficiency and reliability of machine operations. The research process includes the design of precise measuring instruments and a monitoring system utilizing ESP8266 and LoRa Ra-02 technology for data transmission. Fluid sensor data is processed and displayed via a web-based platform and an Android application. The study also involves sensor calibration to ensure accuracy, as well as system performance evaluation through experimental methods, user testing, and data analysis. The results of this research are expected to significantly improve process efficiency and control in weighing machines, providing a strong foundation for IoT technology implementation in operational management within the flour milling industry.

Abstract

Permainan bola basket konvensional membutuhkan ruang luas dan biaya tinggi, sedangkan pencatatan skor manual rawan salah. Mesin basketball arcade ditawarkan sebagai solusi yang lebih praktis dan terjangkau dengan dua kunci teknologi sensor inframerah (IR) untuk mendeteksi bola masuk (skor) secara otomatis, serta aktuator motor DC untuk menggerakkan ring kiri–kanan dan motor servo untuk mekanisme penahan/pelepasan bola agar permainan menantang namun tetap terkontrol. Tujuan dari penelitian ini adalah untuk menghitung poin/score dengan menggunakan sensor inframerah, serta meningkatkan tantangan bermain dengan menggunakan aktuator untuk menggerakan ring ke kiri dan ke kanan. Mesin basketball arcade ini juga dapat menjadi alternatif bermain bola basket dengan ruangan minimBerdasarkan hasil dan deskripsi diatas, dapat disimpulkan bahwa sensor inframerah dapat digunakan untuk menghitung poin/score pada mesin Basketball Arcade, dengan tingkat keberhasilan tertinggi mencapai 82,41% di seluruh mode dan durasi. Serta motor dc dan servo dapat digunakan sebagai aktuator untuk mesin basketball arcade.

Abstract

This research aims to develop the mobility and sensor systems of a strawberry-picking robot so that it can move stably in garden areas and harvest fruit without causing damage. The research method includes the design of the mechanical structure, assembly of an electronic system based on Raspberry Pi and Arduino Uno, and programming of strawberry ripeness detection using the You Only Look Once (YOLOv8) algorithm. The robot is designed with four wheels driven by DC motors, a manipulator equipped with a servo motor, and a distance sensor to maintain the position of the end-effector relative to the fruit. The test results show that the YOLOv8-based detection system is capable of identifying the ripeness level of strawberries with consistent accuracy. The manipulator can adjust its position relative to the fruit and perform automatic picking. The mobility system demonstrates stable movement on uneven terrain and is able to stop automatically when a ripe fruit is detected. The integration between the detection system, manipulator control, and drive system operates in real time, although there is still a slight delay due to the processing limitations of the Raspberry Pi 5. It can be concluded that the development of mobility and sensor systems in the strawberry-picking robot can improve the effectiveness of automated harvesting, minimize fruit damage, and support efficiency in agricultural production.

Abstract

This research, entitled “Fuel Distribution System Using Injection Method with On-Off Controlled Pump”, was conducted at PT Pertamina Patra Niaga Integrated Terminal Makassar. The device was developed as an effort to improve the effectiveness of the fuel distribution process and to reduce the risk of environmental pollution caused by temporary equipment that often leads to fuel spills around the temporary storage tank (sumb tank). The designed system is a permanent fuel distribution system equipped with a piping network, pump and motor control system, and digital pressure measurement. The experiment was carried out using 5,000 KL of fuel as the sample with five pressure variations, namely 10 bar (15%), 8.5 bar (25%), 7 bar (50%), 6.5 bar (80%), and 5 bar (100%), each tested for 5 minutes. The results showed that the highest flow rate occurred at 10 bar pressure with a value of 0.0096 m³/s, although this condition is not recommended because it can cause unstable fluid flow and pump irregularities. When all valves in the injection system are fully open, the pressure becomes stable and the fuel flow remains consistent. The optimal condition was obtained at 5 bar pressure (100%) with a flow rate of 0.1659 m³/s.
