Abstract

Stereo vision has become an attractive topic research in the last decades. Many implementations such as the autonomous car, 3D movie, 3D object generation, are produced using this technique. The advantages of using two cameras in stereo vision are the disparity map between images. Disparity map will produce distance estimation of the object. Distance measurement is a crucial parameter for an autonomous car. The distance between corresponding points between the left and right images must be precisely measured to get an accurate distance. One of the most challenging in stereo vision is to find corresponding points between left and right images (stereo matching). This paper proposed distance measurement using stereo vision using Semi-Global Block Matching algorithm for stereo matching purpose. The object is captured using a calibrated stereo camera. The images pair then optimized using WLS Filter to reduce noises. The implementation results of this algorithm are furthermore converted to a metric unit for distance measurement. The result shows that the stereo vision distance measurement using Semi-Global Block Matching gives a good result. The obtained best result of this work contains error of less than 1% for 1m distance

Abstract

Mi Sehat is one of the output products of the Mie Serdadu UKM. Different from instant noodles in general, which use preservatives, Mie Sehat owned by Mie Serdadu UKM prioritizes consumer health, so it uses organic ingredients and no preservatives. In order to maintain the quality and taste of noodles, it is necessary to use good and healthy preservation techniques for consumers. One way to keep noodles in good condition for a long time is to dry them. The long drying time and the lack of workers are separate problems for Mie Serdadu UKM. In this study, a remote control and monitoring system based on the internet of things was designed that was equipped with an artificial intelligence system to predict the moisture content of dry noodles in the healthy noodle dehydrator machine owned by the Mie Serdadu UKM. The design process uses Esp8266, Raspberry Pi, and PHP Webserver. The communication protocol used is HTTP. The test is intended to determine the time it takes Esp8266 to send and receive data using the HTTP communication protocol. In the artificial intelligence system, the prediction accuracy between th

Abstract

Greenhouse is one of the modern methods of plant cultivation by manipulating environmental conditions according to the desired conditions. To produce healthy and fertile greenhouse plants, several factors are needed, such as temperature, sunlight, water, and soil moisture according to the type of plant. In this study, the design of a sensor node system was carried out as a monitoring of soil moisture and temperature in the greenhouse. In this design, the DHT22 sensor is used as a temperature and humidity detector, capacitive soil moisture sensor SEN0193 as a greenhouse plant soil moisture detector. The readings from the sensor will be processed by the ESP32 microcontroller so that it can be understood by the user, then sends the data to the pump controller node as input in the form of sensor data. The test was carried out several times to find that the output data from the sensor node was data that was in accordance with the circumstances. The soil moisture sensor test SEN0193 was compared with a 4 in 1 soil meter to obtain an average error of 1.15%. The DHT22 temperature sensor test was compared with a temperature thermometer

Abstract

Greenhouse can be made according to the conditions of the season for certain plants as expected, namely by adjusting the amount of soil moisture and temperature. The methodology used in regulating soil temperature and humidity is to make an automatic greenhouse watering device with a web server. To detect temperature using DHT22 and soil moisture using a capacitive sensor v1.2. For actuator, it uses two pumps, namely a water pump and a mist pump. So that the sensor and actuator output can be monitored and stored properly, a monitoring system for temperature and soil moisture in the greenhouse is designed using MQTT communication. Data from the controller node will be processed and sent using an ESP32 microcontroller connected by wifi to the Thingsboard server using MQTT communication. In this system, the web werver delay test, data usage, and testing monitor sensor values and monitoractuator conditions are carried out. From the data from the web server delay test results and the data usage that has been tested, the system takes 2-3 seconds in a single data transfer to the Thingsboard server and data usage in one month requires 386MB of internet data. While testing the sensor values and actuator conditions, the system is able to provide real-time responses and is stored on the Thingsboard server as a monitoring tool in the greenhouse.

Abstract

This paper describes the performance ofreading or recognizing an image using the fisherface algorithm. Fisherface algorithm is a combination of two previous methods, namely Principal Component Analysis (PCA) and Linear Discriminant Analysis (LDA) methods. Where Principal Component Analysis (PCA) will play a role in reducing the complexity of the interrelationships between a large number of observed variables into a relatively small number of linear combinations, which are referred to as principal components. LDA has almost the same function but with a different approach. Fisherface algorithm here plays a role to perform facial recognition or an image reading based on trained set that have been stored in a folder or directory of a database. This study aims to see how the performance of a fisherface in recognizing an image in several external conditions and how accurately the fisherface algorithm can distinguish several images features.Keywords: face recognition, biometrics, PCA, LDA, fisherface

Abstract

Quantum Well Solar Cell ( QWSC) was proposed as a means to achieve higher efficiencies compare with conventional monolithic solar cell structures. Quantum well formed by adding lower band gap material within intrinsic region of p-i-n solar cell with less than 100 Aï‚° thicknesses. In this research, five structure of QWSC device were designed with different quantum well thickness. Each structure using different SiGe mole fraction in order to achieve the influence of mole fraction variation to quantum efficiency (QE). Parameters of SiGe in simulations were obtained from various references to use with PC1D and Simwin Software. From simulation result, quantum efficiency will increase from mole fraction 0.2 (84.5135 %) until reaching maximum efficiency at mole fraction 0.75 (91.5703 %). Quantum efficiency begin to decrease at mole fraction higher than 0.75. At mole fraction 0.85 quantum efficiency equal to 90.4830 % and at mole fraction 0.95 quantum efficiency sharply become 71.6327 %.

Abstract

A dam is a building used as a barrier to retaining river water flow to form a reservoir with water reserves. Some of the uses of dams include irrigation, power generation, and flood control facilities. Most dams also have a section called a water gate, which functions to remove unwanted water gradually or continuously. Dams have different water levels every time due to climate and rainfall, This will affect the water discharge in the dam. The water level in the dam can be utilized to produce potential energy which will later be used for electricity generation. The water flow also affects the productivity of the electrical power that can be generated. Therefore, this research will design an open-close regulating weir water gate of a Merangin Dam miniature using a water level sensor and an Arduino microcontroller. The test is carried out using three water level sensors, each water level sensor has three states so in this research there will be 27 states to openclose the water gate system. Based on the test results, the HY-SRF05 water level sensor has an error range of 0,02% to 21,72% where the measured water level has a higher error when the water level is lower. The test of the YF-S201water flow sensor obtained results where the water level in the dam affects the water flow in the penstock, the higher the water level of the miniature dam, the greater the water discharge in the penstock. Water flow sensor measurements obtained the highest water discharge value of 5,43 liters/minute with an error of 6,77% at a water level of 25 cm in the dam. The test results show that the system of opening and closing the regulating weir water gate can work with the desired conditions and results.Key Words: Dam, Regulating Weir, Water Gate
