The tender process is a long and complex business process to produce a series of legal obligations related to business contracts. The purpose of conducting a tender in government is to support the work program by finding the right tender (provider of goods and services) in the government procurement program so that it can be the basis of their decision to choose the most suitable tender. At the government in Indonesia, the tender process has been carried out using an e-tendering system with the use of internet technology through LPSE. The purpose of e-tendering is to facilitate the procurement process with related parties to increase productivity, effectiveness, and transparency in the tender process. However, problems in the e-tendering system are currently centralized, so that the local LPSE organization has full control of the database and the system which can pose a threat of vulnerability to fraud, collusion, and manipulation practices. The tender selection process that is full of competition must be supported by effective and transparent technology so that it does not cause fraud and suspicion among bidders. Blockchain technology is one of the solutions that allow integrated systems without a third party because it adheres to the decentralized nature of distributed databases so that it has a copy of many users. By adopting blockchain e-tendering can reduce the source of fraud, namely database manipulation. This research will explore the process of developing a blockchain-based system with e-tendering case studies on LPSE.

A smart home uses information technology to manage the devices inside the home to provide convenience for its owners. The most widely used technology for smart home systems is IoT. Nevertheless, IoT has challenges related to data security, moreover for the large scale and distributed IoT network properties. A thing that related to data security is data storage security. One of the data that needs to be secure is the door lock data access. This data must not be vulnerable to counterfeiting and hacking, because a door is directly related to the safety of the homeowner. Door lock access data can be used to find out who and when someone is in or out of the house, hence we can increase the home security if something suspicious happens. However, we must guarantee the integrity of the door lock access data. A method that can be used to ensure data integrity is making a blockchain-based system as data storage because the properties of blockchain are immutable and nonrepudiation. This study uses the Ethereum blockchain platform to store door lock access data and smart contracts to manage the policies. In addition, this study conducts a test to analyze the security level of the proposed system by using an avalanche effect method. The test results show the avalanche effect index for the proposed system is about 96% on average which means the proposed system can be categorized as a secure system.
On each cryptocurrency transaction, a high-level security is needed to protect user data as well as data on the transaction. At this stage, it takes the appropriate algorithm in securing transactions with more efficient processing time. The Elliptic Curve Cryptography (ECC) is one of the cryptography algorithms which has high-level security, and ECC is often compared with the Rivest, Shamir, and Adleman (RSA) algorithm because it has a security level that is almost the same but has some differences that make ECC is superior compared to the RSA algorithm, so that the ECC algorithm can optimize cryptocurrency security in the transaction process. The purpose of this study is to simulate the bitcoin transactions using cryptography algorithms. This study uses the ECC algorithm as the algorithm ECDH and ECDSA key exchange as the algorithm for signing and verifying. The comparison results of ECC and RSA processing time is 1:25, so the ECC is more efficient. The total processing time of ECC is 0,006 seconds and RSA is 0,152 seconds. The researcher succeeded to implement the ECC algorithm as securing algorithms in mining process of 3 scenarios, normal, failed, and fake bitcoin transactions.

Abstrak Smart contract adalah kesepakatan antara dua entitas yang dituangkan dalam kode program. Seluruh transaksi Smart contract disimpan di Blockchain. Blockchain adalah teknologi peer-to-peer terdistribusi untuk menyimpan dan mendistribusikan data digital seperti cryptocurrency dan smart contract dengan adanya kerahasiaan, integritas dan keaslian data. Akan tetapi Blockchain tidak cocok untuk menyimpan data dalam jumlah besar maka banyak developer saat ini membuat suatu DApp yang mengintegrasikan IPFS pada Smart contract Ethereum. File akan disimpan di IPFS sedangkan Blockchain hanya menyimpan hash file dari IPFS untuk dapat mengaksesnya kembali. Pada penelitian ini dilakukan pengukuran pemakaian memori dan CPU saat menjalankan DApp. Terdapat dua parameter yang mempengaruhi pemakaian memori dan CPU yaitu ukuran file dan jumlah node yang berinteraksi. Hasil pengujian akan digunakan sebagai tolak ukur dalam proses perencaanaan kapasitas memori dan CPU dalam menjalankan DApp yang mengintegrasikan IPFS pada Smart Contract. Perencanaan kapasitas hardware memori dan CPU diperlukan agar sistem yang dibangun bisa bekerja dengan baik sesuai kebutuhannya. Kata Kunci : IPFS, Blockchain, Ethereum, Smart contract, Memori, RAM Abstract Smart contract is an agreement between two entities as outlined in the program code. All Smart contract transactions are stored on the Blockchain. Blockchain is a distributed peer-to-peer technology for storing and distributing digital data such as cryptocurrency and smart contracts with the confidentiality, integrity and authenticity of data. However, Blockchain is not suitable for storing large amounts of data, so many developers now make a DApp (Decentralized Application) that integrates IPFS on Smart contract Ethereum. Files will be stored on IPFS while the Blockchain only stores the hashes of files stored on IPFS to be able to access them again. In this study, memory usage measurements were carried out when running DApp through the file upload process. The test results prove that the increase in RAM usage in each file upload process is influenced by file size and the number of nodes that interact with the system. The memory usage test results will be used as a benchmark in the capacity planning process so that the DApp web system can work properly according to its needs. Key Word : IPFS, Blockchain, Ethereum, Smart contract, Memori, RAM
Abstract In recent times data security has become a very big threat and also making our personal data hundred percent secure has become a challenging job. In addition to the above issues the maintenance of these data cost much more, and the user is unaware of his data usage by the third parties. So in creating a network in which the user identity is securely shared where the complete ownership is provided to the user who will have full access to the information that they have provided to the third party. This network can be implemented by using blockchain technology which provides distributed ledger that leads to data immutability and avoidance of central ownership. So by using this technology the data is more secure than before and the user has full knowledge about his own data. Keywords: Blockchain, database, ethernet Cite this Article S. Monisha, V.
