Abstract

Abstrak: Pengembangan ilmu kriptografi mendukung penyimpanan data yang terkomputerisasi karena berhubungan dengan keamanan data perusahaan yang dapat berpengaruh pada operasional perusahaan. Penelitian ini bertujuan melakukan eksplorasi teknik kriptografi symmetric dan asymmetric yang banyak digunakan yaitu Data Encryption Standard (DES) dan Rivest-Shamir-Adleman (RSA). Penelitian ini melakukan modifikasi algoritma DES dan algoritma RSA pada proses enkripsinya. Penelitian ini mengimplementasikan empat algoritma kriptografi yaitu DES, modifikasi DES, RSA dan modifikasi RSA. Penelitian menunjukkan, proses enkripsi algoritma RSA memiliki waktu yang lebih cepat daripada algoritma DES, tetapi algoritma DES memiliki pengamanan lebih baik dibanding dengan algoritma RSA karena proses perhitungannya yang cukup rumit dan sulit. Hasil modifikasi algoritma DES menunjukkan hasil yang kurang baik karena hasil enkripsi memiliki nilai ASCII yang rendah, sehingga jika dikonversi akan menghasilkan karakter ASCII yang tidak nampak. Pada modifikasi algoritma RSA ketika dipilih nilai p dan q yang besar yaitu 19 dan 37, akan membantu proses enkripsi agar nilai ASCII yang tetap dapat dikonversi dalam karakter ASCII. Hal ini memperlihatkan bahwa modifikasi algoritma RSA memiliki hasil yang lebih baik dari modifikasi algoritma DES. Penelitian selanjutnya dapat dilakukan penggabungan algoritma DES dan algoritma RSA yang dilakukan secara sequence untuk melakukan enkripsi data yang lebih rumit, hal ini untuk menghindari penyalahgunaan data.Kata kunci: Data Encryption Standard, Rivest-Shamir-Adleman, KriptografiAbstract: The development of cryptography supports computerized data storage because it relates to the security of company data which can affect company operations. This research aims to explore symmetric and asymmetric cryptography techniques that are widely used, namely Data Encryption Standard (DES) and Rivest-Shamir-Adleman (RSA). This research modified the DES algorithm and RSA algorithm in the encryption process. This research implements four cryptographic algorithms namely DES, modified DES, RSA and modified RSA. The research shows that the RSA algorithm encryption process has a faster time than the DES algorithm, but the DES algorithm has better security than the RSA algorithm because the calculation process is quite complicated and difficult. The results of the DES algorithm modification show poor results because the encryption results have low ASCII values, so if converted will produce ASCII characters that are not visible. In the RSA algorithm modification when a large p and q value is chosen, namely 19 and 37, it will help the encryption process so that the ASCII value can still be converted into ASCII characters. This shows that the RSA algorithm modification has better results than the DES algorithm modification. Future research can be done by combining the DES algorithm and RSA algorithm in sequence to encrypt more complicated data, this is to avoid data misuse.Keywords: Data Encryption Standard, Rivest-Shamir-Adleman, Cryptography

Abstract

The development of financial technology can change the way people conduct financial transactions and quickly convert cash transactions to cashless. This research aims to determine the effect of financial technology, financial knowledge, and financial attitude on bachelor students' financial management behavior. The research methodology used is a quantitative approach, utilizing primary data obtained from 88 questionnaire answers. Data were analyzed using descriptive statistical analysis, instrument test, normality test, multiple regression analysis, and hypothesis testing. The test was assisted by SPSS 22 software. The results show that financial knowledge and financial attitude affect financial management behavior partially. Meanwhile, financial technology has no effect toward financial management behavior partially. Keywords: Financial Technology, Financial Knowledge, Financial Attitude, Financial Management Behaviour

Abstract

In a dynamic economy, the ability to survive is essential. One strategy to survive is to have financial independence. Financial independence can be achieved with good financial management. This study examines the effect of frugal lifestyle (frugal living), financial literacy, and gender on financial management behavior. The sample of this research is 88 students at a state university in Semarang city. With regression analysis techniques, this study shows the results that frugal living and financial literacy have a significant positive effect on financial management behavior. Gender variables are also able to moderate the influence of frugal living and financial literacy on financial management behavior. This research is presented to be able to encourage generation Z in conducting financial management as an effort to achieve financial independence.

Abstract

Currently, the learning process in the field of banking predominantly relies on approaches, focusing on the delivery of theoretical concepts with minimal practical application through personal computer use. As a result, students lack real-world experience related to the operational aspects of banking systems as they occur in the workplace. Therefore, this study aims to design a banking system that integrates various key components of banking activities, with adjustments according to the specific functions of each component

Abstract

The implementation of Supply Chain Management (SCM) makes many businesses manage information, goods, services and money as good as possible so they can provide fast and high-quality services to customers. Therefore, this study aims to implement SCM in Kopi Bintang Salatiga SMEs to decrease production costs, increase revenue, improve operational efficiency and establish good relationships with customers. This study discusses the SCM process and the added value in Kopi Bintang Salatiga SMEs so in the future Kopi Bintang Salatiga SMEs can have good risk management and increase added value. The data was collected through literature study and interviewing the owner of Kopi Bintang Salatiga SMEs. This study found that weather, natural disasters, fires and coffee pests are the factors with the highest risk in the SCM process of Kopi Bintang Salatiga SMEs. The added value of farmers & post-harvest coffee processors of Kopi Bintang Salatiga Kopi Bintang Salatiga SMEs is already quite high at 99%, while at grade I coffee sales is 71% and grade II is 47% it appears that coffee with grade II has lower added value, so it is needing accuracy of coffee processing at farmers & post-harvest coffee processors so the grade I coffee product is increased.

Abstract

Economic uncertainty is inevitable for every individual, including Generation Z. One way to deal with this economic uncertainty is through financial planning, which also includes investment activities. This study aims to investigate the role of financial literacy, social media, and privacy concerns on investment intentions. This study involved 206 respondents who were Generation Z students in Semarang City, Indonesia. The results showed that financial literacy and the role of social media have a positive influence on Generation Z's intention to invest in digital platforms, while privacy concerns negatively affect their intention to invest in digital platforms. However, this study was unable to show a moderating relationship between privacy concerns and the role of social media and investment intentions in digital platforms.
