Abstract

The COVID-19 pandemic has become a major threat to the entire country. According to the WHO report, COVID-19 is a severe acute respiratory syndrome transmitted through respiratory droplets resulting from direct contact with patients. This study of data history is then processed using data mining prediction methods, namely the Polynomial Regression method compared to the Support Vector Machine method. Of the two methods will be sought the most accurate method by testing accuracy with MAE, MSE, and also MAPE to get the results of covid-19 predictions in Indonesia. Based on the comparison of test results through various scenarios against both methods, the Polynomial Regression method obtained the smallest test value, resulting in an accuracy value of MAE = 4146.025749867596, MSE = 19031800.02642069, MAPE = 0.006174164877416524. Polynomial regression is the best-recommended method

Abstract

The very rapid development of information technology has brought tactical and strategic advantages, but it can also be a potential attack from opposing parties on the information and communication systems and networks used, thus opening the way for the emergence of a new war, namely cyber warfare. Cyber attacks are a new threat to Adisutjipto Air Base, which targets vital parts that can impact the organization and make the command and control system ineffective and inefficient. One of the important elements of Adisutjipto Lanud in facing cyber attacks is the readiness of data and communication network security personnel. In the direct or conventional personnel selection process, it is not possible to see the abilities possessed by prospective data security personnel, both in terms of skills, management aspects, analytical aspects, competency weight, and so on. A decision support system can be used to assist decision-making based on existing criteria. This research is limited to only considering the selection of personnel who will become members of komlek or senkom who are responsible for data security and communications networks at Adisutjipto Air Base. In this research, the method used is the profile matching method. The concept of the profile matching method is to compare the selection using the conventional method with the decision support system method in selecting komlek/senkom personnel as cyber security personnel so that differences in competency can be identified, also called GAP (Gross Across Product). The smaller the GAP produced, the greater the weight of the value. large, this means that personnel who meet the requirements have a greater chance of someone occupying that position. The final result of this research is to obtain ranking information for each cyber security candidate based on profile matching calculations to be able to carry out tasks optimally in securing data and networks at Adisutjipto Air Base.

Abstract

UMKM (Usaha Mikro, Kecil, dan Menengah) memainkan peran krusial dalam perekonomian Indonesia, dengan sekitar 64,2 juta unit usaha yang menyerap 97% tenaga kerja. Di tengah dampak pandemi global, pemerintah meluncurkan Pemulihan Ekonomi Nasional, dengan UMKM sebagai fokus utama. Digitalisasi menjadi penting untuk meningkatkan ekspor dan memudahkan pembayaran lintas batas yang aman dan cepat. Hal ini juga menjadi bagian dari agenda Presidensi G20 Indonesia, yang menekankan pengembangan pembayaran lintas negara. Penelitian ini menggunakan pendekatan metode pencarian solusi (solution-seeking) untuk menghasilkan berbagai artefak desain, termasuk arsitektur menggunakan bahasa pemodelan ArchiMate, algoritma, model, dan peranti lunak untuk pembayaran lintas batas. Kami mengadopsi Blockchain Layer 1 Stellar, yang menawarkan protokol terbuka dan terdesentralisasi untuk transaksi mata uang digital dan fiat dengan biaya rendah. Hasil akhir dari penelitian ini adalah model peranti lunak yang memungkinkan pembayaran lintas negara menggunakan Blockchain Stellar, dengan pengembangan yang mengikuti metodologi Disciplined Agile Delivery (DAD). Dengan demikian, penelitian ini berkontribusi pada upaya digitalisasi UMKM dalam menghadapi tantangan ekonomi dan meningkatkan konektivitas global melalui pembayaran lintas batas yang lebih efisien.

Abstract

Big data provides significant benefits across various sectors, including commerce. However, there remained a gap in bibliometric studies examining big data within the context of commerce, leaving research development in this field unclear. This study aimed to address this gap by conducting a bibliometric investigation into researchers' contributions to big data in commerce, including their affiliations and countries of origin. Additionally, the study sought to identify the most productive journals and highlight relevant and under-researched topics within this field. A bibliometric analysis approach was employed, analyzing 396 Scopus-indexed documents and using VOSviewer visualization to identify major recurring issues in the literature. The findings revealed that in 2021, the number of publications on big data in commerce peaked at 97 documents. Maalla, A., from Guangzhou College of Technology and Business, China, emerged as the most prolific author, while China led in publication output with 308 documents. The Journal of Physics Conference Series was identified as the most productive source. Computer Science was the most explored discipline, indicating a strong integration of technology with commerce. Keyword analysis divided research focus into four main clusters: analytical technology, platform optimization, supply chain management, and marketing strategy optimization. These findings provide a foundation for future research to explore areas such as Customer Experience Management, Blockchain Technology, Cloud Computing, Predictive Analytics, and Customer Segmentation, thereby enriching the academic literature and offering practical contributions to data-driven commerce.

Abstract

Accreditation is an assessment activity that determines the feasibility of study programs at a university. College accreditation data comes from various sources and includes multiple data types: semi-structured, unstructured, or structured. Over time, the volume of data will continue to grow and develop, so there is a possibility of data redundancy and a long time to collect the data needed for accreditation activities. The solution is integrating data. This research aims to design a data architecture to facilitate the management of university accreditation data using the Lakehouse data architecture model. All data types can be stored on one platform in the Lakehouse data architecture. In this research, the identification, integration, and data transformation process for university accreditation data is carried out. The data used in this research is academic data in which there are with. The study's results provide an overview of the data flow process in the Lakehouse data architecture model to help better manage university accreditation data. This architecture also supports real-time data analysis so that the accreditation process can be carried out more effectively and efficiently.

Abstract

Penggunaan Oracle exadata pada sistem billing di PT. XYZ membutuhkan biaya ATS (Annual Technical Support) dan ACS (Advanced Customer Service) yang besar sehingga dibutuhkan pencarian software database RDBMS yang sesuai untuk penyimpanan dan pengolahan data dalam proses generate billing di PT. XYZ. Oleh karena itu pada penelitian dilakukan analisis penentuan pemilihan database RDBMS (Relational Database Management System). Metode yang digunakan adalah metode scoring untuk membandingkan 3 database RDMS (Oracle non-exadata, EDB Postgres, dan 11DB Postgres) berdasarkan 5 kriteria yang meliputi penyiapan infrastruktur, migrasi data, tingkat akurasi hitung billing, durasi hitung billing, dan waktu pengerjaan. Hasil penelitian menunjukkan bahwa score database Oracle memiliki nilai paling tinggi di antara database yang lain yaitu sebesar 95, kemudian disusul oleh EDB Postgres dan 11DB Postgres dengan score secara berurutan yaitu sebesar 84 dan 57. Berdasarkan hal tersebut, maka dapat disimpulkan bahwa Oracle non-exadata memiliki performance yang paling tinggi di antara database yang lain.
