Electricity is vital for numerous aspects of human existence, including the operation of electronic devices and the maintenance of vital infrastructure. Even minor electronic devices and essential infrastructures cease functioning without electricity. The industrial and manufacturing sectors depend on a consistent and reliable energy supply because any mismatch between supply and demand can result in significant financial losses. Therefore, a solution is required to address the imbalance between energy supply and demand, particularly in the industrial sector. This study proposes a blockchain-based smart contract for energy auctions that will provide a safe and secure auction system with transparent and low maintenance costs referred to as gas costs, to enable industries to efficiently acquire energy from an energy supplier. The proposed smart contract is secure, effective, and user-friendly.
Lightweight Energy Auction Smart Contract for Industrial Application

Electricity energy as one of the most, if not the most, essential aspects of human life in order to work and cycle well; energizing the minor part as an electronic device, way up to the significant and critical one, would not be possible to not requiring any electricity as the energy supply. No exception to the industrial and manufacturing sector, that colossal energy supply that is constantly reliably needed is so apparent. The condition imbalance of supply and demand, especially on industrial, could lead to numerous losses and significant financial disadvantages. Therefore, a solutive answer for the energy marketplace is needed to toss the imbalance of supplyand-demand issues. Blockchain-based smart contract of energy auction provides a secured auction system with underwhelming maintaining price for industrial to buy energy supply from an energy provider, safe and secured. It is a possible proposed smart contract that is developed to have a strongly secured, convenient, and lightweight.
Lightweight Project Bidding Smart Contract for Industial Sector on Ethereum Blockchain
Allwinnaldo,Revin Naufal Alief,Muhammad Rasyid Redha Ansori,Ikechi Saviour Igboanusi,Jae-Min Lee,Dong-Seong Kim 한국통신학회 2022 한국통신학회 학술대회논문집 Vol.2022 No.2
Smart Contract on blockchain technologies allows people to do various transaction and interaction easily, cheaply, and secured. Smart Contracts could be created for many purposes, one of which is the Industrial Sector. Project Bidding in the industrial sector is one of the common interactions that happen rapidly; traditionally, it costs quite a fortune and demands to invest some time. At the same time, the bidding process needs to be transparent, traceable, inexpensive, and secure. The proposed solution is Smart Contract of Project Bidding on Ethereum Blockchain Network, which allows people to do the simple project bidding activity comfortably, benefitting the blockchain advantage that is decentralized, traceable, and less-fortune-demanding, which only cost way less than 0,001 USD on total cost by doing all the works from start to finish.
MP3 Compression Robust Synchronized Audio Watermarking using QIM on Internet of Things
Allwinnaldo,Jae-Min Lee,Dong-Seong Kim 한국통신학회 2021 한국통신학회 학술대회논문집 Vol.2021 No.11
Internet of Things (IoT) is an innovation that allows people do the work easier, assisted by machinery automation that happened because of communication between devices. The variety of data type that transferred throughout the IoT network is limitless and one of its part of diversity is audio type of file, that usually, the common specific format file for audio is MP3 format. MP3 doing a magnificent job by keeping the size of an audio file low, but the quality of the sound is appropriate, but problems could happen if there is small important information, such as watermark inside of an audio, is accidentally compressed and the audio losing its capability to resist some piracy attempt. Proposed watermarking system is created to make a way for user to do a protection for audio data by using watermarking in QIM-based, but still able to make the size of the audio small by doing MP3 Compression for it, while the sound quality of the audio is considerably favorable without being anxious of the watermark shattered by the compression process and losing its watermark data protection.
