Online information systems with the Single Sign-On (SSO) model are currently widely used by many companies. Single Sign-On (SSO) is an independent authentication model. This system runs on the Hypertext Transfer Protocol (HTTP) protocol. Sending data or information without security is at risk of eavesdropping on information by the authorities. This study aims to compare the combination of Message-Digest and Advanced Encryption Standard (AES) algorithms to improve data security by modifying dynamic keys. The test results show that in each execution the user name and password with the MD5 algorithm are always the same while in the AES algorithm the results are always different so it is safe from replay attacks. So that the Advanced Encryption Standard (AES) algorithm can secure data through the Single-Sign-On authentication process with high-security accuracy.
Tour guides are the critical services for the Travel Bureau. Especially for the services, they provide to tourists. So, a realtime system is needed to be able to interact between the two parties, especially regarding service records in the field and information processing for the Bureau. Based on ScienceDirect library, unfortunately, until there was no reporting system facilitate both parties and recorded in realtime. This study discusses software development solutions that receive various field notes by workers and can be directly viewed online for employers. This research is in the form of a reporting model, which is a solution for the Travel Bureau to have data and be stored electronically on the server. The system was built using a platform that is on a smartphone, so the tour guide reporting system becomes a solution for the Travel Bureau and the Tour Guide to document the trips carried out.
This study aims to analyze how the implementation of the 2019 simultaneous village head elections in Indonesia, and how the challenges of implementing the 2019 simultaneous village head elections in Indonesia. This research uses literature research method with deriftive approach of analysis. The conclusion of this paper is the implementation of simultaneous village head elections in 2019 in Indonesia there are still differences in administrative requirements, caused by differences in the rule of law at the district level, be it the regulation of the selection of village heads in district regulations and at the technical level of regent regulations on the technical implementation of regional head elections. In addition, the challenges in the implementation of village head elections are on voter data collection, regulation of dispute resolution of village head elections, and money politics.
Cabai merah atau Capsicum Annuum L merupakan salah satu tumbuhan dari jenis buah-buahan yang membutuhkan perhatian khusus dalam pertumbuhanya. Tanaman inimembutuhkan kelembaban tanah yaitu 70% - 80% dan suhu udara yaitu 24° - 28°Csehingga dibutuhkan pemantauan kelembaban tanah dan suhu udara secara langsung setiap hari untuk menjaga kelembaban tanah dan suhu udara agar tetap pada yang dibutuhkan, jika kelembaban tanah suhu udara tidak sesuai maka tanaman ini tidak dapat tumbuh dengan baik atau bisa menyebabkan terjadi gagal panen. Oleh karena itu, dirancang suatu sistem purwarupa Smart Farming berbasis IoT yang dapat melakukan pengendalian dan monitoring kelembaban tanah dan suhu udara sesuai dengan yang dibutuhkan oleh tanaman cabai merah. Sistem ini dapat menyiramkan tanaman ketika kelembaban tanah kurang dari 70%, mengendalikan suhu udara menggunakan kipas dengan metode fuzzy dan menampilkan nilai yang telah dibaca sensor pada antarmuka android.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
