Perancangan Sistem Presensi Siswa Dengan RFID Berbasis IoT Menggunakan NodeMCU ESP8266
Get PDFDewantara Sumbang Vocational School has 4 majors, namely Business and Motorcycle Engineering, Multimedia, Graphic Design, and Sharia Banking and the current number of students is quite large, namely 537. The teacher keeps track of attendance for each topic in each class. The student attendance process is carried out manually, namely recording in the attendance book. Attendance book documents are susceptible to damage such as tearing, getting wet, and being lost. So it will cause difficulties during the recording process at the end of the semester and it requires many attendance book documents. Apart from that, it requires storage space for attendance documents. Using RFID in the design of an automatic attendance system to track students\u27 attendance in class and Internet of Things (IoT) infrastructure is the solution to this issue. The study employs a Waterfall method approach, with steps starting with requirements analysis, and moving on to system design, testing, implementation, and maintenance. The research results are the design of an automated student attendance system based on IoT and RFID. The attendance system for 28 students in 1 class takes 16 minutes, 4 minutes faster than the manual attendance system, which is 20 minutes. Teachers can see the results of the attendance data recap through the website interface which includes information on subjects, classes, majors, academic year, semester, names of students present, KBM date, entry time, and class exit time.
 
Desain dan Implementasi Pengolahan Citra Pada Sistem Autonomous Sentry Gun Menggunakan CMUCam5 dan Arduino Mega 2560
Get PDFSecurity is a top priority in various sectors, including military, industrial, and household security. Conventional security systems often require continuous human surveillance, reducing effectiveness and responsiveness. This research aims to address these issues by designing and implementing an Autonomous Sentry Gun system using the CMUCam5 module and Arduino Mega 2560 microcontroller. The system detects and tracks targets automatically, utilizing CMUCam5\u27s vision tracking capabilities to identify objects based on color and shape. The Arduino Mega 2560 serves as the main processing unit, controlling motor movements and firing mechanisms based on data from the camera module. Test results show that the system can detect and follow targets with high accuracy under various lighting conditions. The color yellow with RGB code 255, 255, 0 has the longest tracking distance of 450 cm, while the color purple with RGB code 128, 0, 128 has the shortest tracking distance of 250 cm. This implementation is expected to be applicable in various fields requiring automated security systems

Kegiatan ‘Mystery Box’ untuk Melihat Pemaknaan Kata ‘Anjing’ sebagai Bahasa Keseharian
No full textThe use of the word \u27Anjing\u27 (dog) as part of everyday language in Indonesia has undergone a cultural transformation. The word, originally defined as an animal, has shifted in meaning to become a term expressing a myriad of emotions, often used as a curse word. This social phenomenon is designed to capture the various interpretations of the word \u27Anjing\u27, both its original meaning (langue) and the meanings it has acquired over time (parole). This theme is significant in understanding the intentions behind the use of the word \u27Anjing\u27 in everyday language, whether it is used as an insult towards others or as a word devoid of meaning. The social activity employs an experimental method through the installation of an art exhibit called the \u27mystery box\u27, containing numerous writings related to the word \u27Anjing\u27, as well as audio and video displaying vocalizations of dogs. The results show that late adolescent and early adult subjects quickly interpret the word \u27Anjing\u27 as an insult. In contrast, early adolescent, late adult, and elderly subjects interpret \u27Anjing\u27 as an animal, without any tendency towards using it as an insult. This is supported by the use of different insults in the past and indicates the position of insults as cultural artifacts. Furthermore, the experiment serves as a reminder that each individual has a different interpretation of things, which cannot be imposed by others due to their differing experiences and knowledge
Programming Languages Prediction from Stack Overflow Questions Using Deep Learning
Get PDFUnderstanding programming languages is vital in the ever-evolving world of software development. With constant updates and the emergence of new languages, staying informed is essential for any programmer. Additionally, utilizing a tagging system for data storage is a widely accepted practice. In our study, queries were selected from a Stack Overflow dataset using random sampling. Then the tags were cleaned and separated the data into title, title + body, and body. After preprocessing, tokenizing, and padding the data, randomly split it into training and testing datasets. Then various deep learning models were applied such as Long Short-Term Memory, Bidirectional Long Short-Term Memory, Multilayer Perceptron, Convolutional Neural Network, Feedforward Neural Network, Gated Recurrent Unit, Recurrent Neural Network, Artificial Neural Network algorithms to the dataset in order to identify the programming languages from the tags. This study aims to assist in identifying the programming language from the question tags, which can help programmers better understand the problem or make it easier to understand other programming languages
Audit Energi Listrik pada Bangunan Gedung SMKN 3 Kuningan
Get PDFThis research discusses Energy Audit at SMKN 3 Kuningan with the objective of evaluating the energy consumption intensity (IKE) in the buildings of SMKN 3 Kuningan. The methodology applied in this research involves measuring energy consumption through an energy audit and evaluating the measurement results based on IKE. The results obtained from data processing show that the total electrical energy consumption of the SMKN 3 Kuningan buildings is 112,613.11 kWh/year. Electrical energy consumption in air-conditioned rooms accounts for 80% of the total energy consumption, with electrical energy usage of 7,473 kWh/month, while non-air-conditioned rooms account for 20% of the total energy consumption, with an energy usage of 1,854 kWh/month. The calculated IKE value for air-conditioned rooms in SMKN 3 Kuningan buildings is 1.88 kWh/m²/month. Therefore, the air-conditioned rooms of SMKN 3 Kuningan buildings fall into the very efficient category as the IKE value is < 8.5 kWh/m²/month. The calculated IKE value for the non-air-conditioned rooms in SMKN 3 Kuningan buildings is 0.25 kWh/m²/month. Thus, the non-air-conditioned rooms of SMKN 3 Kuningan buildings fall into the very efficient category as the IKE value is < 3.4 kWh/m²/month. Both air-conditioned and non-air-conditioned rooms in the SMKN 3 Kuningan buildings meet the criteria for very efficient energy consumption intensity. Nevertheless, further research on energy saving opportunities can still be conducted to minimize electricity consumption costs at SMKN 3 Kuningan
