Abstract

Combining Solar power plants electricity sources with PLN electricity sources is expected to save electricity bills because electricity needs are met by two electricity sources, can anticipate the lack of Solar power plants electricity supply, and can anticipate blackouts from PLN electricity sources. For this reason, an automatic control system is needed to switch electricity sources. The control system is the Automatic Transfer Switch (ATS). ATS is equipment that can transfer loads from PLN electricity sources to Solar power plants electricity sources or vice versa automatically if there is a disturbance in one of the electricity sources. This research designs an ATS that is equipped with synchronisation of two power sources using the zero-crossing detector method. The components used are Arduino Mega 2560 Pro Mini as a microcontroller, a voltage detector to detect the voltage of the power source, and 4 10A relays as switches for switching power sources. The result of this research is that there is no delay and wave difference in the load when there is a switch from the PLN power source to the inverter or vice versa. Another condition is that when the PLN power source goes out, the ATS will move the power source automatically to the inverter by only requiring a delay of less than 7 ms to reconnect the power source with the load. Keywords: PLN power source, Solar power plant, ATS, synchronisation.

Abstract

Sentiment analysis or opinion mining, which is one of the application of Natural Language Processing (NLP), aims to find a method to facilitate human in communicating with a computer using their common language. To simplify the process of understanding human language, there are three important stages that must be carried out by a computer, which are tokenizing, stemming and filtering. The tokenizing that breaks down the sentence into a single word will make the computer assume all words (token) are the same. If there is a phrase formed from one of unimportant words, which is happened to be in the stoplist, the phrase will be deleted. Solution for the aforementioned problem is tokenizing based on phrase detection using Hidden Markov Model (HMM) POS-Tagger to improve classification performance using Support Vector Machine (SVM).With this approach, computer will be able to distinguish a phrase from others, then store the phrase into a single entity. There is an increase in accuracy by approximately 6% on Dataset I and 3% on Dataset II in the classification process using phrase detection, due to reduction of missing features that usually occurs in the filtering process. In addition, the detection of the phrase-based approach also produces the most optimal classification model, as seen from the ROC value that reaches 0.897.

Abstract

Missing value sering terjadi dalam metode klasifikasi dikarenakan informasi tentang obyek tidak diberikan, sulit dicari atau memang informasi tersebut tidak ada. Hal ini menyebabkan menurunnya keakuratan dan kualitas data pada saat data diolah. Pendekatan korelasi dilakukan karena peneliti harus mengetahui tentang ada tidaknya dan kuat lemahnya hubungan variable yang terkait dalam suatu objek atau subjek yang diteliti. Metode klasifikasi yang digunakan yaitu metode K-NN, karena metode ini termasuk metode klasifikasi yang memiliki konsistensi yang kuat. Metode ini mencari kasus dengan menghitung kedekatan antara kasus baru dengan kasus lama berdasarkan nilai K atau tertangga terdekat. Pendekatan korelasi dapat dilakukan untuk mengatasi missing value, terbukti dengan meningkatnya hasil klasifikasi dan hilangnya data yang belum terklasifikasi. Kuisioner berfungsi sebagai alat ukur, kuisioner berisi beberapa pertanyaan yang diberikan kepada responden, dari hasil kuisioner dilakukan analisa data untuk mengetahui tingkat korelasi data cadangan. Setelah mendapatkan tingkat korelasi data cadangan, maka data cadangan tersebut digunakan sebagai pengganti data yang terdapat missing value. Sebelum dilakukan penggantian data yang terdapat missing value, hasil klasifikasi dari 500 data adalah jurusan IPA sejumlah 88 siswa, jurusan IPS 126 siswa, jurusan bahasa 271 siswa, dan belum terklasifikasi/false 15 siswa. Setelah dilakukan penggantian data yang terdapat missing value, hasil klasifikasi dari 500 data adalah jurusan IPA berjumlah 102 siswa, jurusan IPS berjumlah 316 siswa, bahasa berjumlah 82 siswa, dan tidak ada data yang belum terklasifikasi. Berdasarkan hasil percobaan yang dilakukan nilai k = 3, 5, 7, 9, dan 11. Dapat diketahui nilai k = 5 memiliki tingkat akurasi yang tinggi dibandingkan dengan nilai k yang lain yaitu 97%, jadi dalam penelitian ini nilai k yang dipakai pada metode K-NN adalah 5

Abstract

Currently, the Indonesian government is promoting the development of renewable energy sources as an alternative to etroleum-based fuels. This effort is reflected in Presidential Regulation No. 40 of 2023, which governs policies on the provision of bioethanol as a biofuel. However, not all bioethanol can be used as fuel; only bioethanol with a concentration above 99%, known as fuelgrade, can be utilized. Due to this problem, there is a need to design and build a device capable of purifying regular bioethanol to achieve fuel-grade concentration, equipped with a monitoring system. This monitoring system is implemented to facilitate the testing and analysis of the purification process. The device uses the pervaporation method for purification, utilizing zeolite nanoparticle membranes as the purification medium. The device is equipped with an MQ3 ethanol sensor as the main component of the monitoring system. To enhance monitoring capabilities, the device is also integrated with a Cyber-Physical System. Thisintegration uses the ESP32 microcontroller to transmit data from the purification device to an Android application and an LCD monitor. This provides ease for researchers in directly monitoring the results of the purified bioethanol. From the research and analysis results, it was found that the Bioethanol Purification Monitoring System provided ethanol concentration readings with an average error of ±4% and an accuracy level of ±95%. The performance of the Cyber-Physical System built can transmit readingsfrom the MQ3 sensor to the LCD monitor both via cable and wirelessly using the Bluetooth protocol controlled by the ESP32. Data can be transmitted continuously over a long period without significant interference. The purification system built can purify ethanol from a 70% concentration to 99% with two purification cycles. The first purification cycle produced ethanol with an 84% concentration (a 14% increase), and the second cycle produced ethanol with a 99% concentration (a 15% increase). Keywords: Bioethanol, Monitoring System, CyberPhysical System, MQ3, ESP32

Abstract

As energy conservation in Wireless Sensor Networks is crucial, the scheduling methods are required to ensure that sensor nodes operate for a longer period. Duty cycle scheduling can be accomplished using synchronous, asynchronous, or on-demand methods with additional radio channels. This study has integrated the on-demand method with an asynchronous scheduling mechanism for the wake-up radio. Model simulation results with random placements showed that the Wake-up Asynchronous On-demand Radio Duty-Cycle (WAORDC) method was able to achieve the latency value of 3.3 seconds, better than the CXMAC asynchronous method, and the total energy required was approximately 4% only, to activate the sensor node.

Abstract

In several major cities throughout Indonesia, the air pollution represents a significant issue. The escalation of motorized vehicle usage yields increased concentrations of carbon monoxide gas, as one of the primary sources of gas pollution. This study introduced a tool designed and implemented for detecting levels of carbon monoxide gas and providing accurate indications. The tool used an MQ-7 gas sensor in combination with a dot matrix display for this purpose.  The detection apparatus was comprised of an IC 74HC595, an ATMEGA16 microcontroller, a BC557 PNP transistor, and a LED dot matrix. The ATMEGA16 microcontroller served as the primary control device of the system. It received input signals from the MQ-7 gas sensor and subsequently converted them into digital format for display on the dot matrix. The IC 74HC595 and transistor BC557 were utilized as the column controller and line controller, respectively, in the 5x8 LED dot matrix.  The gas level measurement at 0 cm exhibited the lowest error of approximately 0.6 %, measuring 300 ppm CO gas levels. On the other hand, at 10 cm, the result showed approximately an error of 6.7 % for a CO gas level of 200 ppm.

Abstract

We present a response surface method to evaluate multi-objective optimization for MEMS-based microheater design. Box pattern, the standard microheater shape, was selected in this study since it has a uniform temperature distribution compared to other patterns. The optimum parameters are used to obtain the maximum total current density and Joule heat.  Based on a hybrid of the Response Surface Method and Central Composited Design, the model simulation emerged with 25 sets of Design Experiments.  As expected, the voltage is proportional to the increased output temperature and Joule heat of the microheater. Material thermal conductivity, anchor length and thickness of the heating element are included as design variables for the optimization. The microheater thicknesses of 4.23 - 4.55 µm, length of 40 µm and thermal conductivity of materials of approximately between 52 to 66 Wm-1K-1 became the optimized results at 1 V input voltage to obtain a maximum Joule heat of 4.9x105 W/mm3 and total current density of 5.6x107 mA/mm2.
