Abstract

World agriculture still faces challenges quite fundamental, it is about the quality issues and the increasing of competitiveness through productivity and the eficiency. This research focused on the criteria of best tomato types and how to apply the Simple Additive weighting method (SAW) into a Decision Support System (DSS) for election best quality tomato that can assist farmers in determining the best type of tomato for renewable energy and supply chain strategy, based on the criteria that have been chosen, such as: tomato size, tomato color, tomato shape and tomato disease. By using the application of Simple Additive weighting method into Decision Support Systems value, it can be concluded that V5 is the best quality tomato and has a predicate value of 83.75 with the fragile values, as follows: 50-69 = Enough, 70-82 = Good, 83-100 = Best.

Abstract

A survey report of the Vietnam Urban Environment and Industrial Zone Association reveals that every day in 2009, about 1,000 tons of construction waste were generated in Hanoi and 2,000 tons Ho Chi Minh City in Vietnam. It is forecasted that the coming years would see a vigorously growing amount of construction waste as a result of the plan to dismantle and renovate old apartment buildings in major cities. So, in this research we developed a supply chain management strategy for the waste controlling in the construction industry. While the bulky volume of construction wastes poses a great environmental threat to urban areas, response to it remains meager. Hence, this paper presents four primary factors affecting the management of construction wastes in Vietnam using fuzzy logic.

Abstract

Proportional Integral Derivative (PID) control is a control system commonly used by industry. Approximately 90% of industrial equipment uses a PID controller because it is easy to use. In the Indonesian Fire Extinguisher Robot Contest (IFERC), the contested robots must follow the contours of the walls of the arena. A Fire extinguisher robot navigation was chosen because the race arena of the competition consisted of walls with different aisles and rooms. The navigation robots used PID control. This study designed and implemented a control algorithm for legged fire extinguishing robots using the PID method, where the PID control was processed in a microcontroller. The angles for each servo motor generated by the calculation of the PID enable the robot to navigate by taking decisions to move quickly or slowly, turn right, turn left and stop. The robot's proximity sensor data and fire sensors enable the fire to be extinguished. The result showed that the robot can carry out its duties optimally.

Abstract

Measuring body temperature depends on the type of thermometer and measured body area. A thermometer placed on the tympanic membrane is considered ideal because the tympanic membrane and hypothalamus have arterial blood supply originating from the carotid artery (neck). Therefore, it is considered directly close to the core temperature. The Tympani Thermometer with external storage can facilitate the doctor's performance in diagnosing patients. This tool is designed using the MLX90614 sensor as a passive infrared sensor that can receive infrared energy from the tympanic membrane. The study aims to design a tympani thermometer. It compared the measurement results of the designed tool with ear thermometers that have been calibrated to get the error value. Based on the results, this prototype works well and has an error of 0.7°C in the left ear and an error of 0.24°C in the right ear.

Abstract

A firefighter is a task given by someone or a team to extinguish a fire that occurs when building a building. The officer took the danger of fighting the fire with a fire engine equipped with a water sprayer. Because of these dangers, a robot was made to help put out the fire. This research aimed to design a fire extinguisher robot using AT89S52 microcontroller as its controller. A DC fan controlled by a relay was utilized to extinguish the fire and a fire sensor (UV-Tron) was used to detect the presence of fire. The robot was driven by motor DC. It could detect the surrounding obstacles and possessed an ultrasound-based navigation system. If the ultrasound system detects an obstacle, the robot will automatically turn without colliding the obstacle or other things around it. The result of the research showed that the proposed fire extinguisher robot can detect fire as far as 5 meters and successfully extinguish the fire.

Abstract

Cardiac tests generally use an electrocardiograph, the results of which are used by medical teams to diagnose heart conditions. Individual ECG examination is held in a health care institution so that it cannot be held independently, considering the high costs and the need for analysis by a specialist.  It is, therefore, necessary to have a functional and portable device to detect heart rate. The heart rate measuring device, equipped with a finger sensor, was designed for adults. The 15-second measurement interval showed the heart rate in one minute and the results were shown on an LCD. The minimum system circuit used ATMega 16.

Abstract

This research will discuss health services in the role of diagnostics and life support. The system designed is a system that is able to provide information on the user's health condition, in this case, is a measure of heart rate and body temperature. In taking heart rate data using a heart rate sensor (fingertip sensor). This system works taking data from the blood flow on the index finger for the 60s, the data will be displayed through the LCD. For body temperature parameters the data collection uses the LM35 temperature sensor. Changes in sensor heat will be converted into electricity, which is translated into digital form through a 10-bit ADC that is processed by the ATMega 16 microcontroller and displayed to the LCD. The results of an ideal measurement show the error of each parameter heart rate and body temperature min 1.702% and 0.55%

Abstract

Two methods are used in a digital pressure meter available in the market, namely positive pressure, and negative pressure. The positive one is used to measure the air pressure on a sphygmomanometer and medical gas pressure at an outlet in the treatment room so that operators can easily check medical gas pressure for the safety of the patient, or they can routinely check to find out how much pressure of the medical gas. Based on the background, the research aimed to design a digital pressure meter equipped with a medical gas measurement mode so that the device can be used to calibrate the sphygmomanometer, suction pump, and measure the medical gas pressure available at the medical gas outlet in each treatment room.
