Abstract

The hospital as one of the individual health service facilities is part of the health resources that are very much needed to support the implementation of health efforts. Hospital information systems can encourage increased efficiency and effectiveness of services in hospitals. The process of planning an information system in a hospital is one of the important points that must be prepared. The Kumala Siwi Kudus Hospital has started implementing online registration, but in its planning the Kumala Siwi Kudus Hospital is still in a hurry so that the implementation experiences several obstacles. When viewed from the benefits generated from the system, it is necessary to evaluate the success of its implementation using an information system evaluation model, one of which is the Human Organization Technology-FIT (HOT-FIT). Primary data collection was carried out by interviews and the results of questionnaires conducted on research subjects. The data obtained is a description of the situation when the research was carried out (cross sectional). The results of this study indicate that there is a significant influence on the construct of system quality on the construct of system use.

Abstract

The purpose of this research is to reduce the factors of SMS security by using SMS encryption application using cipher feedback 8-bits mode on android device. The first factor, which is the physical factor, is if the mobile phone is held by another person who are not the owner of the phone. That person can read and get information from the message on that mobile phone. The second factor is the safety messages in the system, this is all because the provider of mobile phones is only encrypting the messages during the transmission process, while in the storage process in the provider of mobile phones, the messages is saved as plaintext. The step of the process on cipher feedback 8-bits mode is started from filling the SMS with plaintext and initialization vector (IV) and key. Then the encryption function will process them to produce the keystream. The early 8 bits of keystream will be exclusive-or-ed (XORed) by the early 8 bits of plaintext and the result will be sent back to left most block from early IV with shift register process, and these processes will be repeated until resulting a chipertext message filled by rows of hexadecimal. The ciphertext as a result from the system will be sent to the receiver through the server, so the real message which is addressed to the receiver will be safe. Based on the result above, it can be concluded that the message would not be read except by the sender and the receiver.

Abstract

Distribusi merupakan tindakan pemasaran yang memasok barang dan juga jasa antar produsen dan konsumen. Pengaruh yang bermanfaat dari perkembangan teknologi di era globalisasi menyediakan ruang untuk distribusi dalam aspek perdagangan. Proses bisnis distributor makaroni mercon masih belum sempurna, seperti proses sistem penjualan yang masih terdesentralisasi sehingga kegiatan transaksi penjualan produk dan pengolahan data transaksi tidak efisien, efisien, sistematis dan terintegrasi sehingga data transaksi dan laporan penjualan masih belum akurat. Hal ini dilihat berdasarkan hasil wawancara serta hasil observasi. Tujuan adanya penelitian ini untuk memberikan terobosan pengunaan aplikasi sistem informasi penjualan pada Distributor Makaroni Mercon berbasis webite. Penggunaan teknologi ini diharapkan dapat membantu distributor melacak setiap penjualan. Metode Waterfall adalah metode pengembangan software yang digunakan pada penelitian ini. Dengan mengkaji keperluan teknologi saat ini, penulis telah membentuk sebuah aplikasi yang dapat menunjang proses penjualan pada retailer. Dari analisis tersebut dapat disimpulkan bahwa Sistem Informasi Penjualan Mistributor Macaroni Mercon digunakan untuk memenuhi segala kebutuhan dalam proses penjualan yang juga meliputi operasional dan kinerja distributor. melalui sistem informasi penjualan ini dapat membantu distributor dalam proses bisnis penjualan yakni pengelolaan data serta produk sehingga menjadi informasi yang lebih efektif, cepat, akurat dan optimal.

Abstract

The signs that appear due to the covid 19 virus are abnormal human body temperatures (more than 37.5 C). Therefore, it is necessary to build a body temperature measuring device without direct contact to prevent the risk of transmission of the covid 19 virus. This study aims to apply the MLX 90614 sensor to the Arduino-based touchless human body temperature detection system.Extreme programming is suitable where the client is unsure and changes his mind frequently. Extreme programming is suitable for using an iterative approach to developing software. The stages in extreme programming are planning, design, coding and testing. The results of this study can be obtained that measuring body temperature in humans with the MLX 90614 sensor runs smoothly so that it is easier and more practical. The final average of all tests carried out on humans aged 12 years, humans aged 20 years and humans aged 30 years, can produce an average final temperature of MLX 90614 which is 36.77 0C. The final average temperature of the thermogun is 35.32 0C. Then the final average result of the difference between the MLX 90614 sensor temperature test and the thermogun temperature is 1.68. The final average result of the accuracy of the MLX 90614 sensor is 95.52%.

Abstract

The library is a facility owned by educational institutions in their service efforts in the field of education. The role of the library is very important in providing scientific books for students and teachers in an effort to provide maximum service. In today's digital era, books have switched to media, which initially only consisted of sheets of paper and now in the form of digital images or writing. In the library information system, usually in recording using sheets of paper in the form of books, for example book data, borrowing data and others. By using a system that is still manual, there will be a risk of data loss and damage to the ledger, in the process of searching the data it also takes a long time. It will be easier and more practical when the information system is managed well computerized. SDLC is the method used to build a library information system at SD Negeri 01 winduaji because this method is effective and efficient in its implementation. The web-based library information system includes member masters, book masters, transactions, reports, fines and officers who later can input all data using a computerized system to make it easier for librarian. System testing carried out using blackbox testing by Mr. Adimas as the library manager at SD Negeri 01 Winduaji proves that the library information system at SD Negeri 01 Winduaji can run well with a percentage gain of 90% for its success and it is hoped that the management system created can ease the management of the library in SD Negeri 01 as in the master members, master books, transactions, reports, fines and officers at SD Negeri 01 Winduaji.

Abstract

JDC restaurant is a business engaged in the catering sector which provides a form of service for ordering food and drinks both on a large and small scale. The sales system currently used is still manual, this makes the sales transaction process and reporting ineffective and inefficient. This manual process makes the data presented less accurate and has a high risk of errors, damage, and data loss. Based on these problems, it is necessary to have a web based point of sales system where all business processes are computerized so that it is expected to support performance, facilitate and optimize business processes at JDC restaurants. System testing is carried out using black box testing indicating that the system has succeeded in carrying out input, processing, and producing output as expected in the system design.
