Abstrak Website merupakan media yang sangat populer untuk menemukan informasi. Membangun sebuah website diperlukan banyak sekali komponen file yang nantinya disimpan di dalam server. Untuk meminimalisir terjadinya peretasan website, diperlukan keamanan dari sisi sistem dan sisi pengguna. Berdasarkan TOP 10 OWASP, salah satu kerentanan yang biasa muncul adalah bocornya informasi sensitif akibat dari file versioning yang berada dalam server. Demi meminimalisir terjadinya kebocoran informasi sensitif dari kerentanan tersebut, maka penulis membuat program Versioning Catcher Software (VCS) yang berfungsi untuk mendeteksi keberadaan file versioning tersebut. Tujuan dilakukannya penelitian ini adalah untuk melindungi dan mencegah bocornya informasi sensitif di server. Hasil pembahasan dari penelitian ini dapat digunakan untuk meminimalisir terjadinya peretasan server akibat dari file versioning berisi informasi sensitif yang tidak segera ditangani.

Cooperation as one of the driving wheels of the economy also require technology in the implementation of their operations. The application of the information system to the cooperation will affect the cooperative's performance. The Tani Makmur Cooperation in Klaten is a cooperative that helps farmers in managing rice fields, but does not yet have a web-based system that can integrate the required information. In this study, a web-based information system was designed that can be used as data storage, using a waterfall model. Data were collected by observation, interviews, and SWOT analysis. The resulting information system consists of the menu Master Data, Transactions, Reports, Settings, Graphics, Backups, and Help. Cooperation members can carry out storage, borrowing and installment transactions through the Transaction menu. The cooperation admin can view all transactions through the Reports menu. The resulting web-based information system can be used to store cooperation data, thereby expediting and accelerating the transaction process for Koperasi Tani Makmur customers and also reducing the risk of data loss..

The development of information technology has penetrated various areas. This is driven by improved service, rapid increase in information needs and decision making. General elections that are held every time always leave problems about securities and speed of recapitulation. This is because the process is done in the traditional way. This research tries to apply blockchain technology to the e-Voting system security engineering process so that it creates a votes recapitulation process that is fast, accurate and accompanied by transparency values to maintain the reliability of the existing vote and maintain the confidentiality of the vote data being transacted. Transparency and confidentiality of voter data is a fundamental value in general elections or voting that must exist. Seeing this, blockchain technology deserves to be applied because the principles that needed can be met by applying this technology to the e-Voting system.

Pola berulang dan simetris berdimensi dua sering dijumpai dalam kehidupan sehari-hari, seperti pada motif kain, paving jalan, barisan tapak kaki seseorang di pasir. Pola berulang dan simetris tersebut terbentuk dari transformasi, yang terdiri dari translasi, rotasi, refleksi, dan refleksi-glide. Dalam matematika, pola berulang dan simetris pada bidang datar, yang terbentuk dari transformasi, termasuk dalam grup simetri bidang datar. Grup simetri bidang datar ini sering disebut juga sebagai grup kristalografi bidang datar atau grup kertas dinding (wallpaper group). Terdapat 17 grup kertas dinding yang dikenal. Tujuan dari penelitian ini adalah membangkitkan berbagai macam pola dari suatu pola dasar dengan menerapkan konsep grup kertas dinding. Penelitian dilakukan dengan (1) menentukan dan membuat suatu pola dasar yang digunakan untuk membentuk pola lain, (2) membangkitkan 17 pola yang dibentuk dari 17 grup kertas dinding, dan (3) mengidentifikasi pola gambar yang diperoleh dari internet termasuk ke dalam salah satu grup kertas dinding.

The innovation of the robot cars today is moving very fast. The robot car is capable of being driven without using manual remote controls. One form of technological development in robot car control is by using hand gestures. The microcontrolle placed in the palm of the hand will read the direction of movement of our hands, then the instructions are transmitted to the robot car.  The transmission system used in the microcontrolled circuit in the palm of the hand and the receiver circuit inside the robot car must be properly attached. This is influenced by the quality of programming language levels and the arduino mini pro and MPU-6050 circuits. Hand gesture directional readings are able to be easily readable and directly transmitted by the NRF24L01 module via radio waves. The response power of the robot car in receiving hand-move instructions can be received as far as 45 m. In addition to using a good arduino mini pro, the addition of antenna modules will also increase the quality and distance of the connection is getting farther..
