Abstract

Academic Information System (SIAKAD) is an application designed for data management purposes sothat the entire process of academic activities can be managed into useful information. This data isstored in a database, this causes problems, namely the difficulty of backing up data in case of damageand difficulty when validating data because there is no verifier when inputting data, one of the datastored is student transcripts, as we know that transcripts This student score can be used for scholarshiprequirements and applying for jobs so that the transcript must be authenticated. Therefore, the purposeof this research is to design a blockchain-based SIAKAD application that can make it easier to checkdata validation to prove the authenticity of student grade transcripts and display traceability of studentgrade data. Blockchain technology is a ledger that will record all activities carried out then the datawill be distributed to each node that has been determined and already has a certificate authority toaccess the blockchain, then each node will have a copy of each transaction, each transaction will beinterrelated with the transaction next. The transactions made are student value data, the data will bestored into the blockchain. In this study, a blockchain-based academic information system applicationhas been designed using the prototyping method and then using the hyperledger fabric as a frameworkfor building blockchain. The result of this research is a blockchain information system application thatcan verify the authenticity of grade transcripts and see traceability of student grade data.

Abstract

The majority of supply chain management system that are currently implemented are still centralizedsystem. The system has weaknesses such as still having a centralized authority so that it can causesystem security problems, the data is not presented in real time, not transparent and it takes time inprocessing and presenting data. One of the new alternatives that can now be used to overcome thisproblem is to utilize blockchain technology. Blockchain is a decentralized and distributed ledger thatkeeps a record of transactions in a block. Each block in the blockchain contains data from alltransactions in the system over a certain period of time and can create a digital signature that can beused to verify the validity of information related to the next and previous blocks. This research aimedto design a broiler supply chain traceability system through blockchain-based android applicationusing prototyping method. The result of this research is that blockchain-based android application canrecord transactions and information of actors, namely: breeders, companies, collectors, retailers andconsumers and can trace broiler transactions and information in real time and transparently usingBatchID originating from the actors so as to generate Users’ trust.

Abstract

The Hubbu Ahmad Center Foundation is a foundation that focuses on socio-religious activities, helpsmeet the needs of orphans and poor people, and is active in moderate Islamic da'wah activities. TheHubbu Ahmad Center Foundation has carried out various activities including, through donations fromgenerous people but for now the donation system that is running is still using methods such as usingmedia pamphlets as its promotion and Microsoft Excel as its record, therefore there is a need for asystem to manage it so that can be well recorded. The purpose of this research is to create a web-basedonline donation information system that can later be systemized properly using the MySQL database,namely PHPMyadmin, and using structured modeling with UML (Unified Modeling Language) whichuses the Prototype method in it. The final result or system resulting from this research is to be able tobuild a well-database online donation system.

Abstract

Knowledge Management is the process of creating, sharing, using, and managing knowledge andinformation from an organization. A good organization can certainly manage information properly andcorrectly. On the STMIK Antar Bangsa campus there are obstacles regarding tacit and explicitknowledge which are only stored in the individual from various activities such as seminars, workshops,comparative studies and other activities that are followed but there is no place to accommodate theknowledge they have to be able to be disseminated to other lecturers . For this reason, to solve theseproblems, a knowledge management system is needed to manage the web-based lecturer knowledgesharing. This research method uses the Amrit Tiwana model framework with some adjustments and thesystem testing technique uses User Acceptance Test (UAT). The results of the analysis will be obtaineda Prototype of knowledge management system that is suitable for supporting knowledge sharingbetween lecturers at STMIK Antar Bangsa.

Abstract

The bad side of the open access nature of social media is that it frees anyone to have an opinion as they please and is often accompanied by other agendas such as spreading panic, false information, fake news, hate speech and even distorting public opinion. This condition can be fatal in the pandemic era where public opinion can worsen the pandemic situation. Therefore, it is important to know whether it is true that changes in public sentiment in response to news on social media can affect the dynamics of the spread of COVID-19. We use sentiment analysis using machine learning methods to extract daily sentiment data and test its correlation with daily Covid-19 case data in Indonesia. The results of the associative hypothesis test with a Pearson correlation value of 0.151 show that public sentiment on social media towards the news of the COVID-19 variant is positively correlated with the dynamics of the daily Covid-19 cases. Therefore, the author invites all social media users, including the author himself, to be more vigilant and careful in giving opinions and accepting other people's opinions on social media.
