Abstract

A product provider must make the right decisions in predicting the amount of new stock that will be distributed to stalls. Sales of lifebuoy soap in Neighbourhood OF 5 and 6 experienced a difference in the number of sales each month. This of course will make it difficult for the supplier of goods to know the exact number of products that must be stocked. To be able to overcome this and increase the realization of sales from each stall, it is necessary to have a fast and appropriate prediction process that can overcome problems in determining the amount of distribution of new stock. The method used is the Fuzzy Tsukamoto method and is written in the PHP programming language. Where this method is chosen because it is a method of counting with variable words, instead of counting with numbers, human expert systems can be implemented into machine language easily and efficiently. Identification of user needs is needed in the design to determine what features can be used in the system and use story boards to get an overview of the system. System testing using black box by testing all buttons on the application. Based on the results of the study, it can be concluded that this system helps simplify and shorten the time in determining the amount of fulfillment of new stock requests

Abstract

The development of technology is currently growing very rapidly which allows us to access various kinds of data and information, but there are lots of people who abuse this ability, for example phishing activities that often target data and information owned by individuals and companies. Loss of data and information is very detrimental to individuals and companies, where the data and information can be used as a tool for extortion, used as a fraud tool and even the information can be traded. The main reason for the importance of maintaining the security of information is to protect information from online crimes. One of the techniques designed to protect important and confidential information is a cryptographic technique using the Blowfish algorithm and also a QR Code which functions as second line security. where data and information that has been converted into a QR Code cannot be changed. The purpose of this study is to apply the Blowfish Algorithm for Encryption and Decryption of the QR Code into an android-based application system. The results of this study are: The blowfish algorithm can be implemented into an android-based application. Plaintext which is converted into ciphertext using the blowfish algorithm can be used as a QR Code using a QR Code generator. A QR code is up to 7089 numeric digits and 4296 alphanumeric characters. The amount of information will affect the QR Code module, so the symbols in the QR Code will become more complicated. This application has received an assessment from respondents from users with an average value (6.5) with the category of choice "agree".

Abstract

The development of technology is currently running very rapidly, especially in the field of computer networks that make it possible to connect all people from various places. The need for information triggers the rapid development of network infrastructure technology by several vendors or brands. The need for network infrastructure is of course inseparable from the large number of users who use the internet service, causing new problems because the number of users is not proportional to the number of technicians available. For general users, they can wait for the handling schedule from the technician, while for agencies that need a network to complete their work, they don't have that time. To overcome this, you can use a special program to check the network regularly where everyone can use it so that it can reduce free customer service at network providers. One programming language that can be used open source for the development of these applications is python. Python is a multipurpose interpretive programming language with a design philosophy that focuses on code readability. Python programming is still rarely used because it still uses the terminal as the main access where the user has to type certain code to execute the desired result, such as the Command Prompt Windows (CMD) program. The use of python-based applications can be made more comfortable for users by using a GUI (Graphical user interface) display using the TKInter library, which is a standard Python package for creating GUI displays. Tkinter has an interface to the Tk toolkit that can work as an object-oriented layer on top of Tk. Tkinter has many components that can be used to create user-friendly interfaces. Apart from Tkinter, the application uses a subprocess and os library which functions to access the terminal and execute certain comments in the terminal. The built application has functions for pinging, nslookup, ipconfig, network info, active connection and network processes. Ping and Nslookup require data to be entered in text input on the same line, for ping you can input the IP address of the intended network or website address (requires internet connection) while nslookup can be filled in with the website address.

Abstract

Today's technology has undergone many developments, with the development of these technologies can be put to good use. One technology that is currently being developed is in the field of security. Especially in the field of Biometrics because there are two functions, namely identification and verification. Biometrics have characteristics that are not lost, cannot be forgotten, and are not easily faked. Its existence is very close to humans, and one another is not the same so that uniqueness and security can be guaranteed. One of the biometrics that is easy to use is fingerprint, because this fingerprint pattern has high security and the fingerprint pattern is also easy to use. In increasing security, fingerprints can be applied as house door locks, because everyone's fingerprints are different so security will increase and it is not easy to access. The purpose of this tool is made so that it can be applied in the community, with this tool homeowners do not need to carry a key and only require fingerprints, so as to reduce the risk of crime that is rife in the community.

Abstract

This study aims to analyze consumer purchasing patterns at Ryo Jaya Buah Stores using a priori algorithm. A priori algorithm is one of the data mining methods used to find relationships between items in a large dataset through the process of association. This research was conducted by collecting sales transaction data in a certain period at the Ryo Jaya Buah Shop. The data obtained is then processed and analyzed using software that supports the implementation of the Apriori algorithm. The results of this study show a significant variety of purchasing patterns among the products sold in the store. By knowing these patterns, Toko Ryo Jaya Buah can optimize product structuring, marketing strategies, and promotional offers to increase sales. In addition, testing a total of 173 transactions with a support value of 0.02 and a confidence value of 0.01 resulted in a number of rules that can be used as useful new information. After comparing the test results with and without Rapidminer 10.0 software, it is clear that the results of manual calculations are not significantly different from the results of Rapidminer 10.0 software.

Abstract

The caringin shop is a shop that sells daily household and kitchen needs. Caringin shop sales tend to stagnate because in the last few months there has been no significant increase in turnover and tight business competition where the large number of similar shops has become a problem. This requires a precise and careful marketing strategy. This research implements an a priori algorithm as a marketing strategy. The data used was 146 transactions for 1 week. The analysis was carried out manually using Microsoft Excel and libraries in the Python programming language that supports apriori algorithms packaged in a simple web-based application. The analysis resulted in a conclusion that if a consumer buys sugar, then the tendency is to buy coffee with a confidence level of 65% supported by a support value of 10% of all transactions with a lift ratio of 3.9, if buying coffee, then the tendency is to buy sugar with a confidence level of 62% supported by a support value of 10% of all transactions with a lift ratio of 3.9, and if buying eggs, then the tendency is to buy instant noodles with a confidence level of 61% supported by a support value of 11% of all transactions with a lift ratio of 2.8.
