Abstract

Dunia Vape Trading Business is a trading business engaged in the sale of electronic cigarette spare parts. Every consumer who is going to buy a product, the consumer looks at the product shelves one by one to find the product they are looking for. The problem that occurs is that sometimes it is tiring for consumers to search on different shelves or it can also cause consumers not to buy the products they actually need. This is because the products sold are not arranged based on the purchasing patterns that consumers often make. Therefore, a method is needed that can make it easier for consumers to find the desired product and so that UD Dunia Vape can find out consumer purchasing patterns so that it can arrange and provide products according to the usual patterns. Therefore, researchers utilize computer technology to help consumers find the desired product and so that UD Dunia Vape can find out consumer purchasing patterns so that it can arrange and provide products according to the usual patterns. In computer science, one of the methods that can be applied is by using data mining. One of the methods used in determining patterns is the Association Rule Mining Method. Association rule mining is a data mining technique that aims to find association rule patterns between a combination of items. Implementation of the Association Rule Mining Method on sales of goods at the UD Dunia Vape Store is used to provide information on the results of building material sales patterns each month which can be used as parameters in managing UD Dunia Vape's inventory of materials, in addition to providing information on the most popular and most sold building materials at UD Dunia Vape. The results obtained Based on the results and discussion, it can be concluded that the analysis of consumer purchasing patterns using the Association Rule method on Dunia Vape sales transaction data can be applied based on the results of manual method application where the association rule results are the same as data mining application testing, namely if you buy I = LOST VAPE URSA CAP POD KIT JOY PURPLE then Buy N = PODS FRIENDLY ICE PEDIA BLUEBERRY 15MG 30ML (24) with a confidence value of 100% and if you buy N = PODS FRIENDLY ICE PEDIA BLUEBERRY 15MG 30ML (24) then Buy I = LOST VAPE URSA CAP POD KIT JOY PURPLE with a confidence value of 100%.

Abstract

The study of queuing systems has an important role in the development of applied mathematics, especially in probability theory and stochastic processes. Classical models such as M/M/1 generally assume a Poisson arrival process so that the inter-arrival time is exponential, but in real service systems the arrival pattern is often non-Poisson with excessive variance and long tails of the distribution. This research proposes Monte Carlo simulation-based inter-arrival time distribution modeling in two scenarios: constant arrival rate (Scenario 1) and variable (Scenario 2). The interarrival data from the simulation results were analyzed using descriptive statistics and validated with the Kolmogorov–Smirnov (K–S) goodness of fit and Chi square tests for four candidate distributions: Exponential, Gamma, Weibull, and Lognormal. Descriptively, Scenario 1 has a mean of 1.9790 and a variance of 1.3238, while Scenario 2 has a mean of 2.0076 and a variance of 2.4025 and higher skewness and kurtosis. The K–S test results show that the exponential distribution is rejected in Scenario 1 (D = 0.1708; p < 0.001) and Scenario 2 (D = 0.0906; p = 0.0135). In Scenario 1, the Gamma distribution provided the best fit (K–S D = 0.0265; p=0.9808; Chi square = 19.8667; p = 0.2811). In Scenario 2, the Lognormal distribution was the most appropriate (K–S D = 0.0230; p = 0.9963; Chi square = 7.3333; p = 0.9788). These findings confirm that the exponential Poisson assumption is not always representative and that choosing a validated arrival distribution (Gamma/Lognormal) can increase the accuracy of queuing system analysis in both stable and dynamic conditions.

Abstract

Peran majunya teknologi semakin pesat pada era digital saat ini. Internet of things adalah alat yang memungkinkan segala hal di segala kegiatan menjadi lebih mudah dan menghubungkan orang dari jarak jauh ke dekat. untuk mengetahui tentang perancangan sistem rumah pintar yang berfokus pada kontrol untuk membuka dan menutup pintu menggunakan Internet of Things (IoT) ini dalam bentuk prototipe. Konstruksi ini menggunakan arduino uno sebagai pusat kontrol untuk mengontrol proses membuka dan menutup pagar, serta untuk menghubungkan arduino uno ke internet melalui nodemcu esp8266. Thingspeak berfungsi sebagai server dan perantara antara smartphone dan pintu pagar. Berfungsi sebagai perantara, smartphone berfungsi sebagai pengendali dan mengirimkan perintah kepada arduino Uno. Perintah ini selanjutnya diproses arduino Uno melalui esp8266, yang terhubung ke internet. Dengan demikian, perintah awal yang diberikan oleh smartphone Android dapat dijalankan oleh bagian elektronika yang lain, seperti limit switch, motor arus serah, dan buzzer. Dengan demikian, Internet of Things memungkinkan smartphone android untuk mengontrol pintu pagar dari jarak jauh. Tujuannya adalah untuk membuat proses membuka dan menutup pagar lebih mudah dan menghemat waktu. Dengan demikian, yang awalnya diopersikan secara manual, sekarang dapat dioperasikan secara otomatis dan lebih efisien di mana pun dan kapanpun. Hasil penelitian yang didapatkan bekerja dengan baik dari smartphone android yang digunakan untuk mengontrol arduino, sehingga prototype dapat berjalan, server thingspeak mengirimkan perintah kepada arduino uno melalui smartphone. Penelitian ini menggunakan tegangan 7 volt. Pintu pagar membutuhkan waktu ±5 detik untuk ditutup dan dibuka.
