Abstract

A line follower robot is a robot that works along a line. This robot is a very simple type of robot, so it is often used as training material for students who are new to robots. One of the indicators for assessing the performance of a line follower robot is the travel time achieved by the line follower robot in covering various trajectories correctly. The average speed of the robot at 90% and 75% PWM settings is almost the same with a value of around 41 cm/second, while at 50% PWM settings it is much reduced to 35.63 cm/second. At the 90% PWM setting, it can be seen that the path length ratio is 4.32: 2.06: 1, while the travel time ratio is 4.44: 2.66: 1. At the 75% PWM setting, it can be seen that the path length ratio is 4.32: 2.06 : 1. while the travel time ratio is 4.38 : 2.41 : 1. At 50% PWM setting, it can be seen that the path length ratio is 4.32 : 2.06 : 1. while the travel time ratio is 4.09 : 2.09 : 1

Abstract

ABSTRAK Penelitian ini membahas perancangan dan pengaplikasian implementasi teknik pendinginan pada prototipe data center. Seiring perkembangan teknologi maka kebutuhan atas ketersediaan infrastruktur yang memadai sangatlah penting. Data center merupakan infrastruktur yang penting dalam perkembangan teknologi. 30% dari penggunaan listrik keseluruhan pada data center digunakan untuk pendinginan. Oleh karena itu penelitian ini membahas teknik pendinginan mana yang tepat untuk di gunakan pada data center agar mendapatkan efesiensi dan peformansi maksimal. Prototipe dirancang menggunakan Arduino Mega sebagai mikrokontroler, LM35 sebagai sensor suhu, lampu bohlam sebagai sumber panas, dan kipas berukuran 8 dan 2,5cm sebagai sistem pendingin buatan. Dari hasil penelitian yang dilakukan diketahui bahwa cold aisle containtment system lebih baik dalam hal karakteristik suhu. Sedangkan dalam hal karakteristik ketahanan suhu sistem tanpa containtment lebih baik. Berdasarkan hasil penelitian diketahui bahwa untuk data center tingkat 1 dan 2 tidak direkomendasikan menggunakan cold aisle containtment system karena dapat mencapai suhu panas lebih cepat ketika terjadi pemadaman pendingin, sedangkan untuk data center tingkat 3 dan 4 lebih direkomendasikan menggunakan cold aisle containtment system karena menghasilkan efesiensi pendinginan lebih baik di banding sistem tanpa containtment.

Abstract

Speech recognition technology makes human contact with the computer more accessible. There are two phases in the speaker recognition process: capturing or extracting voice features and identifying the speaker's voice pattern based on the voice characteristics of each speaker. Speakers consist of men and women. Their voices are recorded and stored in a computer database. Mel Frequency Cepstrum Coefficients (MFCC) are used at the voice extraction stage with a characteristic coefficient of 13. MFCC is based on variations in the response of the human ear's critical range to frequencies (linear and logarithmic). The sound frame is converted to Mel frequency and processed with several triangular filters to get the cepstrum coefficient. Meanwhile, at the speech pattern recognition stage, the speaker uses an artificial neural network (ANN) Madaline model (many Adaline/ which is the plural form of Adaline) to compare the test sound characteristics. The training voice's features have been inputted as training data. The Madaline Neural Network training is BFGS Quasi-Newton Backpropagation with a goal parameter of 0,0001. The results obtained from the study prove that the Madaline model of artificial neural networks is not recommended for identification research. The results showed that the database's speech recognition rate reached 61% for ten tests. The test outside the database was rejected by only 14%, and 84% refused testing outside the database with different words from the training data. The results of this model can be used as a reference for creating an Android-based real-time system.

Abstract

The issue of waste management has become increasingly important alongside the growth of population and public consumption. Improper disposal of waste types leads to environmental and health problems. To address this, it is necessary to develop technology that can aid in the efficient sorting of waste. This study aims to: first, design and build a waste sorter for organic, metal, and non-metal waste using the ESP32 microcontroller; and second, understand the operating system of the organic, metal, and non-metal waste sorting device. This research utilizes a design and implementation method for the waste sorter based on the ESP32 microcontroller. The device is equipped with capacitive and inductive proximity sensors to detect waste types, as well as a servo motor to direct waste into the appropriate collection bins. The results of this study indicate that: first, the designed waste sorter can sort waste into three categories: organic, metal, and non-metal. Second, the capacitive and inductive proximity sensors can effectively detect waste types at a range of 2-6 cm. Third, the servo motor can drive the sorting mechanism to direct waste to the appropriate collection bins. Fourth, this waste sorter can help improve efficiency and accuracy in waste management.

Abstract

The mangosteen fruit has a characteristic thick skin, so it is difficult to know the condition of the flesh. Farmer can only know damage to the fruit flesh after the fruit skin had opened. Detection of the quality of the mangosteen flesh can be detected using a sensor capable of penetrating the thickness of the mangosteen rind. Flesh quality detection is carried out based on the S21 value (attenuation of mangosteen flesh value) using a portable device equipped with a sensor and capable of emitting microwaves. The S21 value of the fruit's flesh was measured using a spiral resonator that functioned as a sensor. The prototype device consists of an oscillator circuit, a power splitter, and a phase detector with 2507 MHz. Fruit flesh had divided into two conditions: damaged for fruit flesh with yellow sap or Translucent Flesh Disorder, and suitable condition for clean fruit flesh. The results showed that the fruit flesh had an average S21 value of 7.041 dB for damaged flesh and 6.007 dB for good flesh condition. The difference in the value of S21 had used as a reference for detecting the shape of the fruit flesh, with the detection threshold calculated by the Support Vector Machine, resulting in a threshold value of 6.712 dB.

Abstract

The demand for animal products, especially eggs, as a source of easily digestible and high-quality protein, continues to increase significantly. Eggs play an important role in nutrition due to their rich protein content. However, eggs have weaknesses in terms of durability, as they can deteriorate due to various factors such as natural damage, chemical exposure, and microbial contamination that can enter through their shells. Therefore, sorting eggs is crucial to ensure their quality before consumption. Traditional sorting methods commonly used involve using a flashlight in dark rooms or employing water immersion techniques, which have limitations in accuracy and efficiency. In light of these issues, this research aims to develop an egg sorting device using Arduino Uno as the microcontroller, along with a Light Dependent Resistor (LDR) for detecting the condition of the eggs and a Load Cell for measuring the weight of the eggs as the basis for sorting. The results of this study indicate that the combination of these two sensors can minimize errors in the sorting process and expedite egg production activities. Consequently, this device is expected to provide solutions for poultry farmers and egg sellers in enhancing product quality and increasing consumer satisfaction.

Abstract

The advancement of technology in the modern era has driven the development of innovations that facilitate human activities, one of which is through the concept of the Internet of Things (IoT). This research aims to develop a smart mosque prototype based on IoT to prepare facilities before prayer times. The issue faced by several mosques is the lack of a permanent caretaker, which often leads to delays in preparing for worship, such as filling the ablution water or playing the Quran recitation before the call to prayer, as well as the management of facilities like lighting and fans that are not well controlled. The proposed solution in this research utilizes the NodeMCU ESP32 microcontroller, an ultrasonic sensor to detect the water tank capacity to ensure water is available, a DFPlayer Mini to automatically play the Quran recitation before the call to prayer, the MyQur’an API to retrieve prayer times, and the NTP (Network Time Protocol) server to synchronize the system time accurately. Additionally, the Blynk application is used to control the facilities within the mosque. Based on the test results, this prototype system demonstrates good performance in controlling mosque facilities, automatic water filling, and timely Quran recitation playback. However, in the automatic water filling, there is a limitation regarding the high filling threshold, where water overflows at 90% and 95% levels. The DS1307 RTC system has also proven capable of synchronizing time accurately with the prayer schedule from the MyQur’an API, with minimal time difference.
