Abstract

We tested the ISCAS'89 S1423 series with a scan design method, both non-scan, full-scan, and partial-scan, but for the partial-scan, the method we propose uses a structured random approach. The purpose of this study is to determine the evaluation and performance with the best computational time with the proposed method to produce high fault coverage results. Testing the ISCAS'89 S1423 circuit in the form of verilog was carried out using tetramax synopsis, the partial-scan test requires a strategy in determining the flip flop to be used as a scannable flip flop, the test results using the full scan method produce 100% test coverage and fault coverage, but this method provides gate overhead loss of 24.06% and slower chip performance. To reduce the gate overhead loss, a partial-scan method will be applied with the approach of choosing from 74 DFF which will be used as scannable flip flops, the test with the best results we did through the 37 DFF approach with the highest input obtained test coverage of 98.17% and fault coverage 96.76% with 171.11 CPU Time with gate overhead reduced by 12.03%. The next approach with the best results with the approach of 50 DFF highest output plus DFF which is not self-loop obtained test coverage of 99.24% and fault coverage of 98.47% with gate overhead successfully reduced by 16.26% with CPU Time 43.39.

Abstract

The use of digital platforms in the learning process is increasing, especially in the context of assessment activities. In this context, it is essential to realize that digital platforms can be subject to attack or fraud by irresponsible parties. It is due to the presence of sensitive data and/or restricted to a limited number of authorized persons. Therefore, the protection of data and its security in using digital platforms is very important. To enhance this layer of security in data protection, cryptographic methods play a crucial role in maintaining information security. By applying cryptographic methods to learning platforms for assessment purposes, we can increase the security and integrity of the data involved in the assessment process. This research aims to produce a plugin that can be used on a Moodle-based Learning Management System (LMS). This plugin will provide an additional activity in the form of an assessment activity with an essay exam type. When this plugin is used, all questions and answers will be encrypted into text that is difficult to understand by unauthorized parties when an attack attempt occurs. In this way, the learning platform for assessment purposes can safeguard and protect data from access by irresponsible parties.

Seiring meningkatnya berbagai kegiatan penelitian serta kebutuhan pencatatan data yang praktis, maka PUSAIR mulai meningkatkan kemampuan beberapa alat laboratoriumnya dimana salah satunya adalah mekanisme pencatatan data. Sangat penting untuk melakukan pencatatan hasil pengukuran yang praktis, cepat dan tepat agar para peneliti dapat meningkatkan kualitas dan kapasitas penelitian. Namun kondisinya belum semua alat yang ada mendapatkan digitalisasi, salah satunya alat pembacaan ketinggian permukaan air pada model bendungan yang mana masih menggunakan alat ukur manual dan melibatkan beberapa orang untuk melakukannya serta data yang didapat perlu konversi dari catatan dikertas kepada perangkat lunak spreadsheet. Tujuan penelitian ini adalah merancang dan membuat sistem pemantauan ketinggian permukaan air pada model bendungan secara “realtime” berbasis wireless untuk memudahkan pengguna dalam kegiatan pengambilan data percobaan. Rancangan desain sistem terdiri dari 2 buah perangkat yaitu Sensor Node dan Receiver Node yang diimplementasi menggunakan Sensor Waterlevel Sensor sebagai sensor ketinggian permukaan air, mikrokontroler ATMega328 sebagai pengolah data, Xbee-Pro S2C 2.4 Ghz sebagai modul komunikasi, Buck-Converter, DC power Supply sebagai supply daya, serta LCD 16x2 dan buzzer sebagai indikator. Hasil pengujian system menunjukan bahwa komponen dan modul yang digunakan sudah bekerja sesuai fungsi yang dikendalikan mikrokontroler. Pembacaan ketinggian permukaan air oleh Etape waterlevel sensor mampu membaca dengan rata-rata penyimpangan kurang dari 1%. Pengiriman data berhasil mengirim data sebanyak 100% data ke Receiver Node sesuai dengan harapan dan tanpa adanya gangguan koneksi. Pengguna sistem dapat melakukan pengukuran dan perekaman data ketinggian air secara real time dari ruang pantau tanpa perlu mendatangi model bendungan.

Abstract

The number of motorcycle accidents has increased rapidly every year. Many occur due to drowsiness or fatigue because motorists force themselves to keep driving. The state of fatigue while driving is also known as microsleep. To overcome this problem, we propose a design of a prototype system that can be installed on the helmet of a motorized user so that the driver is more alert when driving a vehicle. This system utilizes machine learning technology with the Random Forest algorithm with two prediction results: prediction 1, which means the motorcyclist is tired, or prediction 0, which means the motorcyclist is in a normal state, embedded in the ESP32 microcontroller, and a tilt sensor that can detect signs of drowsiness in motorists. This system design will use the MPU6050 sensor to measure changes in the angle of the motorcyclist's head. The microcontroller will process the data obtained to identify head changes that indicate the possibility of drowsiness. If it occurs, the buzzer will beep as a warning to warn the driver to take a short break. The test results in drowsiness conditions with an angle of 10°–30° resulted in 100% accuracy, and normal conditions only at an angle of 0°–6° resulted in 100% accuracy. The result of the developed system is expected to reduce the number of accidents caused by drowsiness

Abstract

Urbanization and population growth present significant challenges for efficient and sustainable waste management. This research develops an IoT-based intelligent system for waste classification and management utilizing RFID technology, ESP32, a camera, an ultrasonic sensor, and the YOLOv11 object detection model. The system accurately identifies three categories of waste: organic, inorganic, and hazardous. The classification process is automated, incorporating user identification via RFID, servo-controlled bin lid operation, and capacity monitoring through an ultrasonic sensor. Data management is facilitated through a mobile application and a website, which provide user guidance and support for administrators. Test results indicate that the system achieves an average accuracy of 87.5% in the mAP50-95 evaluation, with specific accuracies of 89.0% for inorganic waste, 86.0% for hazardous waste, and 87.0% for organic waste. Despite these results, challenges remain, including object detection errors related to background interference. Future research should focus on enhancing the dataset and implementing data encryption to improve model accuracy and information security. This system demonstrates significant potential for enhancing waste management efficiency and promoting sustainable environmental practices.

Abstract

Penelitian ini bertujuan mengatasi permasalahan penggunaan energi listrik yang kurang efisien, hal ini disebabkan oleh keterbatasan alat kWh Meter konvensional yang tidak memungkinkan pengguna untuk memantau secara langsung konsumsi energi listrik yang sedang digunakan. Berdasarkan permasalahan tersebut, perlu adanya pemantauan konsumsi energi listrik. Sistem yang dibangun dapat memberikan informasi detail terkait energi harian yang digunakan serta menampilkan grafik visual terkait pemakaian listrik pengguna. Sistem ini memanfaatkan ESP32 dan sensor PZEM004T-100A untuk mengukur data-data listrik yang disajikan menggunakan aplikasi berbasis website secara realtime. Metode fuzzy logic diadopsi untuk memprediksi pemakaian listrik ke dalam kategori hemat, normal, atau boros. Sementara, Real-Time Operating System (RTOS) diterapkan untuk proses monitoring dan komunikasi data yang lebih efisien. Selain itu, sistem ini dibangun dengan adanya robotic arm yang berfungsi untuk meningkatkan aksesibilitas pengguna dalam pengisian token listrik secara otomatis. Berdasarkan pengujian pada seluruh sistem berjalan dengan cukup baik, namun masih terdapat rata-rata nilai kesalahan pada pengukuran tegangan dan arus sensor PZEM004T-100A sebesar 0,27% dan 1,58%, serta nilai kesalahan pada perhitungan algoritma fuzzy sebesar 0,71%. Meskipun demikian, sistem ini berpotensi meningkatkan kesadaran pengguna terhadap konsumsi energi listrik harian, serta efektif dalam mengurangi penggunaan listrik yang tidak efisien, melalui pemanfaatan teknologi terkini dalam pemantauan dan pengelolaan energi listrik. This research aims to overcome the problem of inefficient use of electrical energy, this is caused by the limitations of conventional kWh Meter tools that do not allow users to directly monitor the consumption of electrical energy that is being used. Based on these problems, it is necessary to monitor the consumption of electrical energy. The system built can provide detailed information related to daily energy used and display visual graphs related to user electricity usage. This system utilises ESP32 and PZEM004T-100A sensors to measure electricity data which is presented using a website-based application in real time. Fuzzy logic method is adopted to predict electricity usage into saving, normal, or wasteful categories. Meanwhile, Real-Time Operating System (RTOS) is applied for a more efficient monitoring and data communication process. In addition, this system is built with a robotic arm that serves to increase user accessibility in charging electricity tokens automatically. Based on testing the entire system runs quite well, but there is still an average error value in measuring the voltage and current of the PZEM004T-100A sensor of 0.27% and 1.58%, as well as an error value in the calculation of the fuzzy algorithm of 0.58%. Nonetheless, this system has the potential to increase user awareness of daily electrical energy consumption, and is effective in reducing inefficient electricity use, through the utilisation of the latest technology in monitoring and managing electrical energy.
