Abstract

Security is a protection of something that is considered bad or unfavorable and can be detrimental. A website collection of site pages, which are usually summarized in a domain or subdomain, which is located within the World Wide Web (WWW) on the Internet. The WWW consists of an entire website that is publicly available. along with the development of the times the website is increasingly developing through the hands of programmers and developers so that the website is easily accessible, the Hill cipher is a polygraphy based on linear algebra. Each letter is represented by the modulo number 26. With a simple scheme A = 0, B = 1, ..., Z = 25 is used, each block of n letters (considered an n-component vector) multiplied by an inreversible matrix n × n, against a modulus of 26. The Progress of the Times, especially in the field of Technology, makes many people try to steal websites, in an unexpected way and can harm programmers or developers, therefore researchers make applications as a solution to maintain website security by using the Hill Cipher Cryptography method type symmetric encryption algorithm. and for its safety to be better, So the researcher added the 3x3 order as a verification of data encoding. So that programmers and developers can maintain and protect the website that has been created.

Abstract

Absence is something that must be done in the teaching and learning process, generally a university stipulates that attendance has a percentage of 10% on student assessments, besides that as a condition for taking semester exams students must have a total attendance of 50% of the number of meetings, it is not uncommon for students to cheat this by how to entrust absences to classmates. Based on these problems, an automatic attendance tool using NodeMCU-based RFID is made so that attendance is more efficient and there is no cheating. This tool reads the RFID serial number on the student's E-KTP. Absences can only be made according to the course schedule, so when there is no schedule, attendance cannot be made. Apart from that, as a prevention of the spread of the Covid-19 virus, the DS18B20 sensor was added to this tool to detect student temperatures. This sensor is programmed if the student's temperature exceeds 37°C, attendance will fail. To simplify the design of the tool, this study uses the prototype method. The case study was carried out at the engineering faculty of the informatics study program, Darul 'Ulum University, Jombang.

Abstract

water spinach Kale is a nutritious food. The Association of Farmers Groups (GaPokTan) Mekar Jaya Mandiri in Cikupa Village, Karang nunggal, has agricultural land planted with watercress as the main source of income. Watering the water spinach plantations is carried out using a piping system with the distribution of water divided into two groups of blocks which is carried out by adding two ball valve mechanisms as a distribution system. The addition of 2 ball valves created problems for the operator. The work cycle when adding two ball valves is 12 body positions in operating the valve, including walking towards the valve, standing straight, and bending when opening or closing the valve. Walking and bending when opening or closing the ball valve takes a long time. Productivity was increased by developing two ball valves with an automatic valve system called the Motor Operated Valve (MOV). MOV uses an albino program for its operating system, and the operator controls M0V via cell phone. Comparison of work cycles between ball valves and those using MOV. The working time cycles for the redesigned operator open and close the valve is 63 seconds with 12 movements. The longest time is walking towards the valve, which is 16 seconds. After the redesign, the operator only needs a cell phone to operate the valve application so that the movement goes to the valve is 0 seconds, and the work cycle time after the redesign is 6 seconds

Abstract

Kerupuk (Crackers ) are one of the specialties of the Indonesian people and are well-known by all social classes, from the lower to the upper middle classes. Most Indonesians consume crackers because they are delicious and can be consumed with any meal. This resulted in the proliferation of cracker manufacturers in Indonesia, not only producing a single type of cracker but also a variety of crackers whose flavor and ingredients were adapted to the palate of the Indonesian people. Crackers made from leather or Rambak crackers are well-known among the general population. Rambak crackers are not significantly distinct from other types of crackers. The difference is in the ingredients. Rambak crackers are made from various ingredients, including cow, buffalo, rabbit, chicken, fish, tapioca flour, and flour. In making these Rambak crackers, however, cowhide is typically employed. Cow leather is one of the products of the livestock sector, which, according to the Central Statistics Agency of Jember Regency, produced 11,287 pieces of leather in 2019. This demonstrates that Rambak tapioca cracker ingredients are not readily available on the market. Consequently, a Decision Support System (DSS) is a system that can provide problem-solving and communication capabilities in semi-structured and unstructured environments. Positive Distance from Average (PDA) and Negative Distance from Average (NDA) are the two distance measures used in the Evaluation Based on the Distance from Average Solution (EDAS) method. The best alternative will be the one with the highest PDA value and the lowest NDA. Based on the User Acceptance Test (UAT) results of the system, which the Wanteyan Home Industry well received, this decision support system yields 5%.
