Abstract

Fire is one of disasters in Indonesia. From several fire cases, buildings are the most dangerous locations. This is due to the difficult process of evacuation which one of them caused by panic victim. To solve these problems will be made a robot rescue that can guide the victim to find a safe evacuation. Rescue robots have sensors that can detect fire, and smoke to determine which areas are dangerous to pass. Robot made with a rocker bogie system that is able to pass obstacles with good stability. Robot also equipped with a compass and ultrasonic sensors to guide the movement in search for a safe place. To find the fastest and safest path, the robot has an artificial neural network algorithm (ANN). With this algorithm, robot can find a safe and fast path. Learning process is done by referring errors that occur. From the learning process any errors or errors will continue to be fixed. In order for the dimensions of the robot not too large, the computation of ANN is embedded in a 32-bit microcontroller STM32F4. The result of this research is a prototype of rescue robot equipped with ANN algorithm. From the test that has been done, the robot success to find the safest path with the accuracy of 75% with an average speed of 25.49 seconds. Keywords: Rescue robot, Rocker-Bogie, STM32F4, and Artificial Neural Networks --- Kebakaran adalah salah satu bencana yang sering terjadi di Indonesia. Dari beberapa kasus kebakaran, gedung bertingkat merupakan lokasi paling berbahaya. Hal ini dikarenakan sulitnya proses evakuasi yang salah satunya disebabkan oleh kepanikan korban. Untuk mengatasi hal tersebut maka akan dibuat sebuah robot penyelamat yang mampu memandu korban mencari jalur evakuasi yang aman. Robot penyelamat yang dibuat memiliki sensor yang bisa mendeteksi api, dan asap untuk mampu menentukan area yang berbahaya untuk dilewati. Robot dibuat dengan sistem mekanik rocker bogie yang mampu melewati halangan dengan kestabilan yang baik. Robot juga dilengkapi dengan sensor kompas dan ultrasonic untuk memandu pergerakanya dalam mencari tempat yang aman. Untuk menemukan jalur tercepat dan teraman, robot memiliki sebuah algoritma jaringan syaraf tiruan (JST). Dengan algoritma ini robot mampu mencari jalur yang aman dan cepat. Proses learning dilakukan dengan mengacu pada error yang terjadi. Dari proses learning tersebut setiap kesalahan atau error akan terus diperbaiki. Agar dimensi robot tidak terlalu besar, komputasi JST dilakukan secara embedded dalam sebuah mikrokontroler 32-bit STM32F4. Hasil dari penelitian ini adalah sebuah prototype robot penyelamat yang dilengkapi algoritma JST. Dari pengujian yang telah dilakukan, robot berhasil menemukan jalur teraman dengan akurasi 75% dengan kecepatan rata-rata 25.49 detik. Kata kunci: Robot Penyelamat, Rocker-Bogie, STM32F4, dan Jaringan Syaraf Tiruan.

Abstract

Decision support system has become one of the necessities that should be owned in a company which can help to estimate a situation by giving ratings. One of the example is to give assessment on the Job so that it can assist in monitoring the Work and estimate their underlying problems. There are many methods that can be applied in the assessment process one of them is profile matching method, which the assessment process is done by comparing the actual value with the target value has been determined to get value of competence-called gap. The small gap value affects the final value of the calculation method of profile matching where small value gap shows the actual value approaches the target value. Once it is done from the process of ranking the final value obtained to determine the effectiveness of a work.

Abstract

A hot aluminum alloy AA6082 and nickel disc of 560 °C and 850 °C was cooled by a spray nozzle with the spray flux of 4.2, 10 and 13.7 kg/m2s. The temperature history during the cooling process was recorded with use of an infrared camera. The energy balance equation is the basis for the numerical procedure of Heat Transfer Coefficient (HTC) calculation in the film-boiling regime. It is found that HTC is almost independent from kind of metals. HTC has a stronger function of surface temperature. With use of single droplet model in film boiling developed, vapor film thickness can be calculated to predict this trend.

Abstract

Quadcopter is an unmanned aerial vehicle with 4 rotors and propellers on each side. All motions, positions and flying directions are controlled by the speed and direction of each rotor movement. Application of this quadcopter technology also varied, such as for distant aerial observation and militer duties. In the application of this technology, the balance of quadcopter is needed, four rotors will always be parallel to the horizontal plane. This condition is known as hovering control. Hovering control often got distractions from outside, among others is the dynamics of the plant tend to be complex. In this study used methods of Hybrid PID-Fuzzy control as its control system to achieve a balanced condition and resolve any distractions when hovering control happen for roll and pitch angles. Hybrid PID-Fuzzy control is combination method of PID control (conventional PID) with output value generated from fuzzy logic control. Constants of Kp, Ki and Kd are used and added with fuzzy logic control using 25 rule evaluations. Percentage of each control is 90% for PID control and 10% for fuzzy logic control. With constant Kp=6.62, Ki=0.85, Kd=5 with 25 rule evaluations, this control can generate good response by reducing overshoot and provide better recovery time compared with conventional PID control. Implementation of Fuzzy-PID hybrid control generates an error steady state response about 3o during hovering and being able to hovering back within 1.5 seconds if the given disctraction is 19o and 1 second if the given distraction of 13 o.
