Abstract

The increasing demand of electricity and number of distributed generations connected to power system greatly influence the level of power service reliability. This paper aims at improving the reliability in an electric power distribution system by optimizing the number and location of sectionalizers using the Ant Colony Optimization (ACO) and Simulated Annealing (SA) methods. Comparison of these two methods has been based on the reliability indices commonly used in distribution system: SAIFI, SAIDI, and CAIDI. A case study has been taken and simulated at a feeder of Pujon, a place in East Java province of Indonesia, to which some distributed generators were connected. Using the existing reliability indices condition as base reference, the addition of two distributed plants, which were micro hydro and wind turbine plants, has proven to lower the indices as much as 0.78% for SAIFI, 0.79% for SAIDI, and 2.32% for CAIDI. The optimal relocation of the existing 16 sectionalizers in the network proved to decrease further the reliability indices as much as 43.96% for SAIFI, 45.52% for SAIDI, and 2.8% for CAIDI, which means bringing to much better reliability condition. The implementation of the SA method on the considered data in general resulted in better reliability indices than using the ACO method.

Abstract

Royal Jelly is a nutritious food that has many benefits, thus increasing the demand for the product. Royal Jelly can be produced by bees 121 times/year, but the large amount of production is not matched by a good harvesting system, namely using the conventional method by prying out the queen cup. If the harvesting process is carried out in large quantities, farmers will have difficulties and have an impact on product quality, when the harvest time of royal jelly is getting longer, the quality of royal jelly will decrease, especially in the aspect of viscosity. Then an automatic royal jelly harvester is needed to speed up the harvesting process. In an automatic royal jelly harvester, a system that can detect and measure the distance of royal jelly is needed, namely by image processing using a camera. The results of the RGB segmentation test were obtained with a binary image thresholding value with a lower limit (220,220,220) and an upper limit (255,255,255) while the HSV method obtained a binary image thresholding value with a lower limit (0,0,240) and an upper limit (179,80,255). The detection rate of the HSV color space method gets 100% accuracy compared to the RGB color space method which gets 60%. In addition, measuring the distance of Royal Jelly with millimeters using a camera can be done using the Euclidean distance method and the percentage of error is relatively small (3%) from the actual distance.Keywords: Royal Jelly, Image Processing, Eclidean Distance

Abstract

Royal jelly is one type of bee product that has many benefits and high nutritional content. The characteristics of royal jelly are classified as easily damaged if the queen cup is left open for a long time, so the quality of the royal jelly produced is not good. Poor quality will affect the important ingredients in royal jelly which can reduce the amount of royal jelly production. Unfortunately, the harvesting tools used today do not have measurements and monitoring of the composition of weight and royal jelly that support it. Therefore, the purpose of this research is to design a monitoring system for weight and sucrose in royal jelly based on the Internet of Things. The system is equipped with accurate measurement of sucrose content, measurement of harvest weight, and real-time data transmission that is stored through the database. Measurement of sucrose level monitoring was carried out using the TCS-230 sensor resulting in an error percentage of 3.002% and was in accordance with ISO standards. In addition, the results of the measurement of the first harvest weight of 26.2 grams then increased until the fifth harvest, which was 113.2 grams. With Internet of Thingsbased monitoring, the value of sucrose content, weight, time, and date that can be seen through the android application aims to make it easier for users to view incoming realtime data and automatically recap data.Keywords: Royal Jelly, Sucrose, Weight, Internet of Things.

Abstract

Royal Jelly is a product produced by honey bees and has many benefits, thus increasing the demand for the product. This high demand is considered not effective because the harvesting system is is carried out using conventional method, by removing one queen cup at a time. If the harvesting process is carried out in large quantities, farmers will have difficulties and this will impact on product quality, because the amount of royal jelly increases within 72 hours, but begins to decrease after 96 hours of larva removal. Therefore, an automatic royal jelly harvester is needed. In this research, the process of designing back up power and setting the conveyor speed. The results of this study, it can be seen that the system is capable of for 30 minutes using an accumulator, when the power goes out. While on the conveyor speed system, the conveyor is able to run at the desired speed according to the in the specified distance range, so that the queen cup object can stop at a position that can be reached by the royal jelly suction for the harvesting process.Keywords: Royal Jelly, Back Up Power System, Duty Cycle, Conveyor

Abstract

The iodine clock reaction is a chemical reaction that consists of two different colorless solutions mixed into one container to produce a colorless solution and a few moments later the solution turns dark blue. This color change is used as a timer for the stopping mechanism for the chemical-powered car prototype in the Chem E Car team of Universitas Brawijaya. The injection syringe used to inject the iodine clock solution can affect the reaction time of the iodine clock solution due to the difference in pressure at the time of injection so the mixing speed varies. The injection system of iodine clock solution aims to reduce the error of the reaction time of the solution so that it becomes more constant. The system is also equipped with the Internet of Things (IoT) concept which aims to monitor the state of the iodine clock solution such as the temperature of the solution because the competition time is quite long, about 10 hours so that the iodine clock solution must be monitored while not in use. This study uses the YF-S401 sensor as an indicator of the volume of the iodine clock solution. In addition, the system uses an actuator, namely a solenoid valve as a valve for the ex

Abstract

Vehicle counting is considered as one of the most important applications in traffic control and management, for detection and counting of vehicles must be carried out. Efficient real time vehicle counting can improve control in traffic management by aiming to efficiently collect real time traffic information. In vehicle detection and counting system, vehicle detection and counting is very important for traffic flow in monitoring, planning and control. Traffic flow is monitored using a computer vision paradigm, where images or sequences of images provide improvements to the road view that are used to detect vehicles, monitor and count the number of vehicles in traffic flow. The system works by capturing video streams such as vehicles in the monitored area to compute information and transferring compressed video streams to provide a video based solution which is mainly implemented in OpenCV by Python Programming and using You Only Look Once (YOLO) is an approach for real-time object detection based on a Convolutional Neural Network.

Abstract

Energy plays a very important role in human life. Every year, the demand for energy needs continues to increase and the majority of energy generation uses fossil fuels. So an environmentally friendly energy source is needed. One of the environmentally friendly energy sources is fuel cells. Themain problem with fuel cells is that the output voltage is unstable and changes depending on the pressure, temperature, and use of the fuel cell's composition. So one of the electronic equipment that can increase and stabilize the output voltage in the fuel cell is needed, namely the Dc-Dc flyback converter using PI (Proportional Integral) Control. The use of a flyback converter with a designed PI control has a role to set the PWM on the flyback converter switch. In this study, the Implementation of the PI Control Algorithm on the Dc-Dc flyback converter used voltage feedback. The purpose of this study is to design and analyze the performance characteristics of the PI controller in stabilizing the output voltage of the flyback converter even though there are changes in load and input voltage. In this study, there were two tests on the design results, namely testing the response of the flyback converter on the open loop and the close loop which was given PI control with the direct synthesis method. The results showed that the flyback converter has been successfully created and is able to produce an output voltage of 2-3x from an input voltage of 24Vdc. The converter is capable of producing a voltage of 63.6 Vdc with a duty cycle of 50% with an efficiency of 83.57%. From the close loop test, there will be variations in input voltage and load, the flyback converter output voltage can be kept constant at 72 volts with steady state error and relatively small settling time values. Sothe performance of the PI controller with Dc-Dc flyback converter in regulating the dc-dc output voltage of the flyback conveterter can respond to changes in input voltage, load, and setpoint stably and effectively.

Abstract

Energy is one of the main sources in human daily life, the resources are divided into two part, it is renewable and non-renewable resources. In the 21st century, fuel cells has been known as a technology which can produce electrical energy and heat energy efficiently and cleanly. This fuel cell is a renewable energy category, therefore it will be environmentally friendly. Then, to support the performance of fuel cell, it requires a tool namely DC-DC converter. DC-DC converter is an electronic circuit that is used to increase or decrease the DC voltage value. There are many kind of topologies for this converter, one of them is the flyback topology. The flyback topology is a relatively simple topology than the other topologies, especially for the low power category. In this flyback converter circuit there is a transistor controlled ignition circuit, namely Pulse Width Modulation (PWM). The function of PWM is to compare the DC reference signal waveform with a triangle. There are variation of duty cycle value in the PWM control circuit which is regulated by the Arduino microcontroller. In this converter there is a transfomator to increase the DC voltage valueas it was expected. The sensors used in this flyback converter are current sensors and voltage sensors, in order to display data results accurately.
