Abstract

Potato production in Indonesia has grown very rapidly, making Indonesia the largest potato producer in Southeast Asia. However, there are challenges for farmers in growing potatoes. Such as treating potatoes for various diseases. 2 diseases will occur in potato plants if not treated quickly, namely early blight disease caused by the fungus Alternaria solani and late blight disease caused by the microorganism Phytophthora infestans. The project "Potato Plant Leaf Disease Detector (MR-PoLod)" aims to design an android application that can classify leaves on potato plants into 3 classifications, namely healthy, early, and late blight disease. This application uses the CNN (Convolutional Neural Network) Machine Learning Algorithm because currently, CNN is recognized as the most efficient and effective model in pattern and image recognition tasks. This application uses the Python programming language which is rich in library and framework availability so that it can meet the needs of machine learning and image classification tasks. The total data used for training data, data validation and data testing is 3165 images. With each division of the data process on the training data of 70%, validation of 15% & testing of 15% to test the effectiveness of the model that has been created. The performance of MR-PoLod for each class, obtained a precision value, recall, and f1-score of 0.99. Likewise, the accuracy value achieved by the model is 0.99 or 99%. Thus, the expected application can facilitate farmers in classifying diseases on potato plant leaves.

Abstract

Pada perumahan padat penduduk, ruang terbatas menjadi salah satu tantangan utama bagi penghuni dalam melakukan aktivitas sehari-hari, termasuk dalam proses menjemur pakaian. Jemuran konvensional sering kali memakan ruang yang signifikan dan kurang efisien saat kondisi cuaca berubah tiba-tiba, seperti hujan atau kekurangan sinar matahari. Penelitian ini bertujuan untuk merancang dan mengimplementasikan sistem jemuran pakaian otomatis berbasis Arduino Nano yang dapat dioperasikan secara mandiri untuk memaksimalkan penggunaan ruang dan meningkatkan efisiensi pengeringan pakaian. Sistem ini dilengkapi dengan sensor hujan dan sensor cahaya yang secara otomatis mengendalikan pergerakan jemuran. Ketika terdeteksi hujan, jemuran akan ditarik secara otomatis untuk melindungi pakaian, dan akan kembali terbuka saat kondisi cuaca kembali cerah. Metode penelitian melibatkan desain perangkat keras dan perangkat lunak yang terintegrasi dengan Arduino Nano, serta pengujian performa sistem dalam berbagai kondisi cuaca. Hasil penelitian menunjukkan bahwa sistem jemuran otomatis ini berhasil berfungsi secara optimal dalam merespons perubahan cuaca, dengan waktu respons cepat dan penghematan ruang yang signifikan di area perumahan padat penduduk. Implementasi teknologi ini diharapkan dapat menjadi solusi praktis untuk meningkatkan kenyamanan penghuni dan efisiensi penggunaan ruang di hunian urban yang terbatas.   Kata kunci: Jemuran Otomatis, Arduino Nano, Sensor Cuaca, Hunian Padat, Efisiensi Ruang.

Abstract

Thin-film solar cells made of hydrogenated amorphous silicon have succeeded in crystallization technologies as a less expensive alternative because of their straightforward design, sparse material requirements, low processing temperatures, and cheap manufacturing costs. A multi-chamber plasma-accelerated chemical vapor deposition apparatus driven by radio frequency was used to create the intrinsic and extrinsic layers of the a-Si: H solar cell. Multi-chamber allows us to upgrade each layer of the gadget utilizing a distinct space, preventing cross-contamination throughout the procedure. To enhance cell conversion efficiency, a thorough analysis has been conducted in this work to evaluate the manufacturing process and comprehend the link between process factors and property dependency. Our findings demonstrate an amorphous Si: H solar cell with a maximum cell efficiency of 6.52%, Voc 880 mV, Isc 11.33 mA/cm2, and FF 65%. We think that a modeling method followed by manufacturing can further enhance the performance of a-Si: H-based solar cell devices.

Abstract

This study analyzes transformer oil from the GT 2.1 transformer at PT PLN Nusantara Power using the Dissolved Gas Analysis (DGA) method. Transformers are crucial for power systems, and their performance relies on the condition of their oil, which acts as both an insulator and a coolant. The DGA method detects gases like hydrogen, methane, ethylene, ethane, and acetylene in the oil, which indicate electrical or thermal faults. Oil samples were analyzed using diagnostic techniques such as the Rogers ratio, Duval triangle, and IEC standards to assess potential faults. The results revealed faults like thermal overheating and electrical discharges, offering valuable insights into the transformer’s health. The study highlights the importance of routine oil testing and DGA for predictive maintenance, enabling early fault detection. This proactive approach helps prevent failures, reduces outages, and extends transformer lifespan, ultimately enhancing the reliability and efficiency of power delivery at PT PLN Nusantara Power. The findings support the integration of advanced diagnostic methods in maintaining critical electrical infrastructure.

Abstract

This study examines how methane flow rate during the plasma-enhanced chemical vapor deposition (PECVD) process affects the electronic properties of amorphous silicon-carbon (a-SiC) thin films. The films were deposited with varying methane flow rates, and their structural and electronic properties were analyzed using spectroscopic ellipsometry and atomic force microscopy (AFM). Results show that the methane flow rate influences the ratio of sp2 to sp3 carbon bonding, which impacts the material's electronic band structure. Higher methane flow rates increase sp2 carbon content, reducing the bandgap energy and enhancing electrical conductivity. In contrast, lower flow rates lead to higher sp3 bonding, wider band gaps, and decreased conductivity. This study highlights the potential for optimizing methane flow rates in PECVD to tailor the electronic properties of a-SiC films for specific applications. The findings offer valuable insights for designing and optimizing a-SiC materials for electronic devices. Future research will investigate how other deposition parameters and post-deposition treatments affect a-SiC's electronic properties, aiming to further improve material performance for advanced technological applications.
