Abstract

One of the fundamental devices in electronics, Integrated Circuit (IC), is usually applied in more complex devices. Before the IC is used, it has to pass some tests to guarantee that its function is in accordance with the specifications. Automated Test Equipment (ATE) is used to test many electronics devices, including ICs. Nowadays, with the rapid advance in electronics technology, the industry will need more advanced ATE to fulfill customers demand. One of the applicative solutions is improvement and integration of a standalone module in commercial ATE owned by the company. ASL 1000 Test System is one of the ATE that is still widely used in industry. ASL 1000 has one limitation in one of its module, Digital Driver and Detector (DDD). The limitation is how much vector pattern that can be saved in the memory. Based on the observation in DDD instrument, a standalone module that has similar specifications as DDD can be designed using Field Programmable Gate Array (FPGA) as its base component. In the standalone module plan, supporting circuits are used, these are interface circuit between FPGA and PC using RS-232 and ASIC as ATE drivers or comparators to connect FPGA and device under test (DUT). The result of the study shows that the designed module can receive and send 8-bit data at 19.200 baud rate. It can write and read 16-bit data from and to SDR SDRAM within 90 ns and 80 ns for one cycle. It can control DAC type AD5308 in standalone operation and DAC type AD5676 in daisy chain operation to generate specific voltage in specific channel. In behavioral simulation, main controller module has already worked in accordance with the desired specifications.

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 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

Wireless Sensor Network (WSN) merupakan jaringan nirkabel untuk memantau kondisi fisik atau lingkungan, seperti suhu dan kelembapan, yang kemudian data tersebut diteruskan melalui sebuah jaringan kepada suatu lokasi (komputer) di mana data tersebut dapat diamati dan dianalisis. Tujuan utama WSN adalah menyediakan komunikasi nirkabel berdasarkan jaringan sensor berbiaya rendah dengan konsumsi daya yang sangat terbatas. Sehingga konsumsi energi merupakan permasalahan yang menantang pada WSN. Untuk mengurangi konsumsi energi pada WSN, protokol routing harus diterapkan. Salah satu tantangan pada routing yang terlibat dalam WSN, yaitu lalu lintas data yang dibuat memiliki redundansi (data yang tidak perlu/dibutuhkan) yang signifikan dalam sebagian besar kasus. Selain itu, perangkat WSN bergantung pada baterainya sebagai sumber listrik, sehingga masa pakai jaringan tergantung pada level baterai yang tersisa pada setiap node. Teknologi yang digunakan tiap node untuk saling berkomunikasi juga mempengaruhi konsumsi energi yang ada. Maka pada penelitian ini dirancang sebuah WSN yang berfokus pada pengiriman data dari tiap-tiap sensor node hingga mencapai sink node dengan mekanisme routing berdasarkan daya baterai pada node, sehingga data akan diteruskan melalui node yang memiliki daya terbesar. Protokol komunikasi yang digunakan adalah BLE yang sudah tertanam di ESP32. Metode komunikasi yang digunakan adalah connection-oriented atau master-slave, dengan shared-slave topology (SST) sebagai topologinya. DHT22 digunakan untuk mengukur suhu dan kelembapan relatif. Dari hasil percobaan, DHT22 memiliki error pada pembacaan suhu sebesar 1,935%, sementara pada pembacaan kelembapan udara memiliki error sebesar 1,90%. Hasil algrotima routing yaitu node menentukan dan mengirimkan data suhu dan kelembapan kepada node yang memiliki daya terbesar dengan rata-rata waktu 8,957 detik. Serta rata-rata waktu yang diperlukan oleh node untuk mengirimkan data suhu dan kelembapan kepada sink node yaitu 16,952 detik dengan 3 kali hop.

Abstract

Data center memiliki peranan yang sangat penting sebagai pusat penyimpanan seluruh perangkat TI baik dari server yang besar hingga pusat komunikasi data perusahaan. Perangkat-perangkat tersebut tentunya dapat menghasilkan panas yang cukup tinggi mengingat penggunaan yang dilakukan secara terus-menerus. Di sisi lain, sebuah perangkat juga berpotensi untuk menghasilkan embun jika kondisi ruangan data center terlalu dingin. Oleh karenanya dibutuhkan sebuah sistem yang dapat digunakan untuk mendeteksi perubahan suhu dan kelembapan udara pada ruang data center. Pada penelitian ini telah dibuat sebuah alat dengan sistem yang mampu mengirimkan data secara real time ke thingspeak menggunakan NodeMCU ESP8266, sehingga suhu dan kelembapan dapat di pantau. Pada penelitian ini, error rata-rata suhu dari DHT11 yang digunakan sebesar 2.91%, sedangkan error rata-rata kelembapan sebesar 1.47%.
