Abstract

Cryptography is a scientific discipline used to maintain data security. To increase the level of security, cryptographic development is needed by implementing 64 bit Block Cipher Cryptography based on the Joglo traditional house image pattern. This approach produces random ciphertext, which is useful in changing data in the form of clear messages (plaintext) into messages that cannot be understood (ciphertext). The designed pattern is 64 bits long and then converted back into plaintext. This cryptographic design is based on the description of the Joglo traditional house, using encryption and decryption processes combined with XOR operations. The S-Box substitution table is used for byte transposition, which aims to obtain Ciphertext. The research results show that the 64 bit block cipher cryptographic system by applying the avalanche effect to the Joglo traditional house image pattern can be considered an effective cryptographic system. The correlation value achieved reached 53.125%, validating its ability to maintain data security.

Abstract

Forecasting is the initial stage in production planning and serves as a foundation for subsequent production activities. The advent of the Covid-19 pandemic in Indonesia began in 2020, causing unstable sales. The ARIMA or Autoregressive Integrated Moving Average method is a medium-term forecasting method that generates relatively good prediction values compared to other methods. PT Gratia Husada Farma is a company active in the pharmaceutical field in Central Java. The sales data possessed by PT GHF is not yet optimally utilized and only serves as historical records. Through the obtained data, a sales forecasting analysis is conducted using the ARIMA method with parameters p, d, q of 1, 0, 1. Evaluation of the method using the RMSE formula results in a value of 2.229 (0.02229). This shows that the ARIMA method analysis has an acceptable error value, less than one of the critical values or alpha of 0.05.

Abstract

Every year, routinely PT. Enseval Putera Megatrading held several events which were held face-to-face and online and involved many parties, from the employees' board of directors and external parties as sources. The events held include: National Work Meeting (RAKERNAS), Mid Year Work Meeting, Product Launching, EMDP Graduation, Enseval Anniversary, Innovation Forum, and others. There are at least 3 stages that the Event Owner must go through in organizing and achieving the goals of an event, pre-event starting from the formation of the committee to determining the concept of the event that will take place, running events starting from registering participants who are present in the event to maintaining the event's run down, post events ranging from gathering feedback on events to publishing materials. An event management system is absolutely necessary to support the success of the event. Valent, which is a React Native based mobile application, is the right step to answer this need. React native is an application that is used using the JavaScript programming language to create applications in developing applications on smartphones based on Android and iOS. (Zammetti, 2018) This allows Valent to run on 2 OSes at once (Android & IOS) so that all event participants can enjoy the benefits of the Valent application directly from their respective smartphones.
