Abstract

In this research Trigonometry Technique was implemented to predict the ball movement direction for Wheeled Soccer Robot Goalkeeper. The performance of goalkeeper robot in Wheeled Soccer Robot Contest is very important. The crucial problem with goalkeeper robot is the delay in ball detection by the camera because the results of the camera images captured are always slower than the pictures that have been captured. This causes the robot's response to blocking the opponent's kick ball being late. Trigonometry Technique is one technique that can be used to predict the direction of the ball movement based on trigonometry mathematical formulas. The input data used is the location of the last ball position (x?last ball and y-last ball) and the location of the current ball position (x-current ball and y-current ball). The outputs are the prediction of the next ball location (x-predict ball and y-predict ball) and the prediction of ball movement direction prediction. The results are the goalkeeper's robot successfully predicts the opponent's kick direction with 90% accuracy and can predict the location of the next ball very well. By implementing this method, it is expected to optimize the performance of the goalkeeper robot in saving the goal.

Abstract

ISPATINDO, a steel melting factory with production capacity 3360 tons/day, operates the electric arch furnace (EAF) to transform steel into liquid at Steel Melting Shop (SMS). It is then conveyed to another machine for further process until it becomes billet and wire rope. During its operation, the electric arc furnace once exploded on March 3rd, 2004.The explosion made 13 workers get wounded and even some died. Up to now, EAF components have frequently been damaged and repaired prior to the scheduled replacements.This condition makes index of reliability of EAF decrease significantly. If there’s no action to improve the maintenance strategy, component failure which may cause accident couldhappen. This research used the International Safety Rating System (ISRS) to determine the maintenance strategy on the electric arc furnace machine. ISRS method was used to obtain critical program which would serve as the main input in the preparation of maintenance strategy. With this strategy it was expected that ISRS could increase the effectiveness of production and prevent against the occurrence of occupational accidents, losses onmanagement, equipment, materials and environment.

Abstract

Mayoritas nelayan tradisional menggunakan tempat penyimpanan sederhana seperti kotak styrofoam, peti kayu, dan palka sederhana dengan media pendinginan es balok. Penyimpanan tersebut belum memiliki insulasi yang baik sehingga berakibat pada kualitas ikan yang menurun. Belum lagi keluhan terkait cepat rusaknya box ikan yang terbuat dari styrofoam tersebut. Kekurangan kotak ikan berbahan styrofoam adalah sangat mudah rusak dan berlumut. Beberapa penelitian memberikan solusi untuk menginsulasi palka dengan beberapa bahan insulasi seperti polyurethane, sekam padi, aluminium dan sebagainya. Penelitian ini bertujuan untuk menurunkan laju perpindahan panas pada palka ikan kapal 7GT dengan variasi kevakuman dan persentase es terhadap ikan. Konstruksi insulasi dibuat sedemikian hingga dengan variasi fiberglass dan polyurethane dengan ketebalan tertentu diharapkan dapat meningkatkan masa pemakaian fish hold menjadi lebih lama.

Abstract

The utilization of the Crushing and Barge Loading Conveyor (BLC) systems is important in coal processing. A crushing system is required as a tool for the process of crushing coal into smaller sizes and then transferring it to the stockpile. While a BLC system is needed to transport coal from the stockpile to the barge. In general, the control and supervision systems for crushing and BLC systems are carried out separately by two operators. However, the distance between two operators causes a time lag information. In this research, we create a Supervisory Control and Data Acquisition (SCADA) system with the type of Multiple Programmable Logic Controller (PLC) on the Crushing and BLC systems using Profinet communication integrated by two PLCs with one Human Machine Interface (HMI) and WinCC. The system is equipped with real-time data, automatic control, and online surveillance with smartphones via the S7APP application. The error resulting from the reading of each component by the HMI and smartphone reaches 0%, while for automatic control, the system works very well, having a success rate of 100%.

Abstract

The performance of Savonius wind turbine was improved in the previous experimental studies that added overlap and variation of disruptive cylinder distances in front of returning blade. However, the study could not display flow visualization such as velocity contours, streamlined velocity, and pressure contours on turbines so further research is needed. This research is in the form of numerical study using 3-dimensional Computational Fluid Dynamics (CFD) method. The simulation is, determine visualize the turbine’s flow like a velocity contours, streamlined velocity, and pressure contours. The turbine has the same diameter and height of 0.4 meters with overlap addition. The various distances of the disruptive cylinder used is S/d = 1.4; S/d = 1.7 ; S/d = 2 and S/d = 2.3. The final result shows that the visualization at a distance of S/d = 1.7 is the most optimal wake distance to cover the overall returning blade side so that the performance of the Savonius wind turbine at that distance is highest compared to other variations.
