Abstract

AbstrakSistem pembayaran elektronik (e-payment) dianggap sebagai tulang punggung e-commerce. Agar diterima secara luas metode pembayaran di seluruh dunia, sistem e-payment harus mengikuti protokol keamanan yang efisien yang menjamin keamanan yang tinggi untuk transaksi online. Secure Socket Layer (SSL) dan Secure Electronic Transaction (SET) merupakan dua protokol yang  banyak dibahas untuk mengamankan pembayaran kartu kredit online. Namun, SSL maupun SET telah gagal dalam implementasi pada pengguna akhir, sehingga munculah protokol Secure Electronic Payment (SEP) yang merupakan protokol e-payment yang aman dan efisien yang menawarkan lapisan tambahan perlindungan bagi cardholder dan merchant. Tujuan penulisan ini untuk menentukan protokol mana yang paling cocok untuk keamanan e-payment berdasarkan perbandingan pada end-user implementation requirements. Metode yang digunakan berupa studi literatur dengan melihat karya terkait yang membahas mengenai protokol SSL, SET, SEP yang selanjutnya akan dilakukan perbandingan. Hasil yang didapatkan dari perbandingan protokol keamanan e-payment SSL, SET, dan SEP berdasarkan faktor end-user implementation requirements (usability, flexibility, affordability, reliability, availability, interoperability) yaitu bahwa protokol SEP yang memenuhi syarat dan paling cocok untuk diterapkan dalam keamanan e-payment. Kata kunci: SSL, SET, SEP, security requirements of e-payment, end-user implementation requirements

Abstract

The competition level between companies on executing product marketing is rapidly increasing, so the companies have to understand the importance of correlation between external environments of company with consumer’s needs. One of the efforts that can be done is by utilizing data warehouse and the application of infrastructure in information and technology field. This research combined Association Rules  method to extracting pattern and finding every possibility that potential to increase sales and Holt-Winter Multiplicative method to estimate the alteration of trend on the seasonal data. After passed through data processing process by using RapidMiner tools, information that consists of correlation pattern between rule that describe the comparison of product and the sales working area and season that affects the product sale. The pattern used by company to know which product is often purchased by customer. Besides that, this research produces changing trend data of PT ABC’s product that generated by result of previous data comparison with forecast data. Based on value of error rate Mean Absolute Percentage Error (MAPE) in estimating forecast result on the PT ABC’s sales transaction data during 3 years, it shows good level of accuracy. Result of data test, by considering rule that formed and forecast result so the company can control and manage product in order to avoid incorrect sales. This thing will effect on repression of operational cost and PT ABC can identify available opportunities to increase sale of agricultural medicine.

Abstract

The use of information technology in the management of Micro, Small, and Medium Enterprises (MSMEs) is not limited to business performance and productivity but also aspects of data security and transactions using various mobile, website, and desktop-based applications. This article offers an idea to explore cybersecurity awareness and risk management of MSME actors who adopt information technology. The research method used is qualitative with a case study approach in the Coffeeshop X business and the Y Souvenir business in Salatiga City, Central Java, Indonesia. The data collection technique used in-depth interviews, observation, and document studies. These findings indicate that Cybersecurity Awareness, especially information security awareness, can be reviewed based on knowledge, attitudes, and behavior. Risk management can be review based on supply risk, operational risk, and customer risk. Cybersecurity Awareness and Risk Management in MSMEs is holistic and cannot be generalized, so it needs to be discussed contextually based on case studies. In the context of Coffeeshop X and Souvenir Y, the level of Cybersecurity Awareness (knowledge, attitude, behavior) is not always linear. In addition, risk management is more dominant in the customer risk dimension, compared to supply risk and operational risk.

Abstract

This study aims to determine the characterization and comparative test of exterior and interior qualities including egg weight, eggshell thickness, egg shape, air cavity and interior including high albumin, egg yolk, and haugh egg unit from egg strain Isa Brown and Hyline Brown in different areas of Deli Serdang and Langkat regencies, North Sumatra Province in June-July 2017. The eggs used in this study were 400 eggs divided by 100 Isa Brown and 100 Hyline Brown from Denai Village, Pantai Labu Subdistrict, Regency Deli Serdang, then 100 Isa Brown and 100 Hyline Brown from Sei Limbat Village, Kecamatan Selesai, Langkat District. Each egg is collected directly from the chicken and then measured against the exterior and interior. The results showed that the characterization and comparative test of chicken eggs consumption of strains of Isa Brown and Hyline Brown in different regions had results(thit> ttable) with t test on comparative test I1: H1 and I2: H2 meaning egg of different strain showed different result also on egg weight parameter, shapeegg, shell weight, air cavity, egg white index, haugh unit, egg yolk index and yolk color. The comparative test I1: I2 showed no significant differences (thit <ttabel) on egg weight, shell thickness, shell weight, egg white index, haugh unit and egg yolk index, but showed significantly different (titable) results in egg shape, air cavity and yolk color, meaning there is environmental influence but not significant to other quality of egg with same strain in different region. In the H1: H2 comparative test the results were not significantly different (thit <ttabel) on all parameters except the color of egg yolks, meaning that no environmental or strain effect produced eggs of the same quality in different regions.

Abstract

The 2019 elections in Indonesia was slightly different from the previous elections because the elections were held simultaneously. It made more difficult for the community to make their choices. Public was faced with a larger number of candidates who were not necessary known as legislative candidates’ socialization is very important. This research discussed the process of network formation and network structure that was formed. Data collection was carried out through observation, interviews and questionnaires with 50 respondents as research samples. The data obtained were processed using the UCINET tool which was then analyzed using Social Network Analysis (SNA). The results showed that the process of network formation occurred because of interpersonal contact between actors, the experiences of being a successful team and relationships history between actors. The network structure formed was closed with a high level of communication density that is 0,976. It was meant that all actors made communication each other intensively. The actor who became the network booster was actor id#02 which always appears in every click that was formed.

Abstract— The use of smartphones is very widespread in today's society. Android is widely liked by various circles of users as well as among smartphone manufacturers with its very interesting features. However, even though this smartphone technology has many features, users still have special considerations for SMS (Short Message Service) email. Unfortunately, this SMS feature has limitations, only in the security of exchanging confidential information, this system is needed to provide secure information exchange via Android-based SMS. Therefore, it is necessary to secure it using cryptographic methods and a high level of security is required. In this study, we will compare three cryptographic algorithms, namely AES (Advanced Encryption Standard), RSA (Rivest Shamir Adleman), and TEA (Tiny Encryption Algorithm) which is carried out by comparing the characteristics of the encryption algorithm, the results of which will be used for an Android-based SMS security system with better security. higher. Based on the findings of the review it can be concluded that TEA (Tiny Encryption Algorithm) is the best algorithm for this work for an SMS security system on Android.
