Abstract

This study articulates a deep learning approach for classifying Carnatic and Non-Carnaticmusic using Convolutional Neural Networks (CNN) and Recurrent Neural Networks (RNN). Thedifferential features, such as microtones, and improvisational structures of Carnatic music causesevere difficulties in the application of automated genre classification. Thus, audio features ofMFCCs, chroma features, and spectrograms were extracted to capture key spectral and tonalproperties in order to realize excellent classification. The CNN model achieved an accuracy of 95.1%,outperforming the RNN model's 93.8%, with ROC-AUC scores of 0.96 and 0.94, respectively. Thesemetrics indicate the CNN’s effectiveness in handling complex spatial features in audio data, while theRNN provided valuable insights into sequential patterns. This Result highlights CNN’s advantages incapturing the intricacies of genre classification for culturally rich music forms like Carnatic. Futureresearch will focus on increasing the performance of such models, and leveraging both spatial andtemporal dimensions in audio might happen using hybrid CNN-RNN architectures. Also, this researchcontributes to the advancement of technology around music classification with promising avenues tocultural preservation and digital archiving of music.

Abstract

Blockchain transformative technology that enables secure, decentralized, and immutable transaction recording through a network of cryptographic blocks, enhancing transparency and trust without the need for a central authority or intermediaries. The Ethereum platform builds upon this foundation by facilitating the development of decentralized applications (dApps) and smart contracts, which automate processes and improve operational efficiency. In higher education, the Student Activity Credit Unit (SACU) system exemplifies the application of blockchain by managing both academic and non-academic achievements, thus promoting a holistic approach to student development and enhancing essential soft skills like leadership and teamwork. By leveraging a decentralized system built on Hyperledger Besu, the SACU ensures that student records are secure, transparent, and scalable, while providing real-time monitoring and verification of achievements. This paper evaluates the decentralized student’s achevements record model, demonstrating its improvements in transparency, security, and efficiency over existing systems, ultimately preparing graduates for professional success and fostering trust in the recognition of their qualifications.

Abstract

Construction companies must focus on occupational health and safety (K3) and must cover the safety and welfare of workers. JKK (Work Safety Committee) has carried out various safety assessments and risk assessments to improve worker safety and health. Comfortable Housing Boarding House PT. has carried out a risk assessment using the Prima Land method to assess the risk and safety of construction projects. The study found 13.3% of risks were classified as extreme, 30% high risk, 13.3% moderate risk, and 43.34% low risk. Risk assessment methods will be used in this research to further improve K3 working conditions and ensure worker safety. This study identified three main factors that influence OHS health and safety: organizational culture, environment, and risk assessment methods. By implementing these measures, construction companies can improve their OSH safety and health management section and reduce the risk of accidents and injuries.

Abstract

Research on the "Effect of Magnetic Field Variations on Fuel Channels on the Efficiency of Consumption and Exhaust Emissions on Gasoline Engines" focus on how magnetic fields with various forces can increase the efficiency of fuel consumption and reduce exhaust gas emissions in gasoline -fueled engines. In this study, the magnetic field was applied to the fuel channel with the aim of affecting the combustion process in the engine. The strength variations of the magnetic field used are expected to optimize fuel combustion, so that fuel consumption becomes more economical and exhaust emissions, such as oxygen (O₂), carbon monoxide (CO), carbon dioxide (Co₂), and hydrocarbons (HC), can minimized. The results showed that the application of magnetic fields has the potential to have a significant impact on engine efficiency, especially at certain rotation, which can create environmental benefits with cleaner gas emissions and reduce overall fuel consumption.

Abstract

The automotive industry faces challenges in improving fuel efficiency and reducing exhaust emissions. One solution being developed is the Hydrocarbon Cracking System (HCS), which breaks down hydrocarbon molecules in fuel to enhance combustion efficiency. This study aims to analyze the effects of HCS on engine torque and exhaust emissions (CO, HC, and CO₂) in a four-stroke, single-cylinder gasoline engine. The research method involves an experimental factorial design of 6 × 2, testing torque and exhaust emissions at various engine speeds. Measurements were conducted using a dynamometer and a gas analyzer to compare standard conditions with HCS implementation. The results indicate that HCS increases engine torque by 3.40% and reduces CO and HC emissions by 28.12% and 54.35%, respectively. However, CO₂ emissions increased by 12.48%, indicating more complete combustion. Overall, HCS proves to enhance engine efficiency and reduce harmful emissions, making it a potential eco-friendly solution for motor vehicles.
