Abstract

Pemerintah telah menyiapkan program Bantuan Pangan Non Tunai (BPNT) untuk membantu masyarakat miskin dan membutuhkan. Bantuan Pangan Non Tunai (BPNT) harus disalurkan secara tepat, teratur, dan transparan untuk memastikan bahwa penerima bantuan memang benar-benar mereka yang membutuhkan. Oleh karena itu, diperlukan suatu sistem yang dapat mengubah data menjadi informasi dan mengidentifikasi calon penerima bantuan sembako nontunai maupun yang tidak berhak (BPNT). Sistem prediksi yang akan dibuat pada proyek ini menggunakan RapidMiner 7.1 untuk pengujian dan Algoritma C4.5, metode klasifikasi dari data mining. Hasil Implementasi Data Mining dengan metode Algoritma C4.5 untuk memprediksi kelayakan penerima dan hasil penerima bantuan pangan nontunai (BPNT) diperoleh nilai akurasi prediksi sebesar 99%, yang kemudian divalidasi oleh aplikasi RapidMiner 7.1 dengan akurasi hasil 98,50%.

Abstract

he oil and natural gas sector is a sector that is used with great importance for Indonesia's national development. An interesting commodity to watch out for in the oil and gas industry is liquefied petroleum gas (LPG). LPG is a hydrocarbon gas that has been liquefied under pressure to facilitate storage, transportation, and handling and the main ingredients consist of propane/C3, butane/C4 or can be mixed to produce mixed LPG..At this time PT. BLORA MUSTIKA does not focus on when household needs increase and when not, the meaning of this is that LPG gas data is not used properly and is only recorded, this of course makes PT BLORA MUSTIKA unable to predict demand from sub-distributors and results in frequent an empty supply of LPG gas causing difficulties for the community to obtain 3 Kg LPG gas. This problem can be calculated and compared with the Multiple Linear Regression and K-Means methods.By using the Multiple Linear Regression and K-Means method, it is hoped that it will make it easier for PT. BLORA MUSTIKA in determining demand predictions from sub-distributors so that there is no shortage of LPG gas supplies and which method can be obtained which is more effective and efficient.

Abstract

Kemajuan teknologi saat ini memaksa segala pekerjaan yang dilakukan oleh manusia dituntut untuk cepat dan tepat. Dengan semakin berkembangnya teknologi seperti saat ini, pasti akan berdampak pada segala aspek, salah satunya adalah aspek penjualan sembako. Komputerisasi merupakan salah satu solusi agar kita sebagai pelaku bisnis dapat melakukan pekerjaan secara cepat dan efisien.                 Penelitian pada Toko sembako Bapak Nasrul  ini dilakukan menggunakan metode pengembangan sistem extreme programming dengan tahapan yaitu planning Planing tahap ini peneliti melakukan perencanaan dalam mamahami konsep kebutuhan sistem yang akan dibangun. Tahapan Kedua Design data yang di peroleh dari planing kemudian di rancang menggunakan UML. Tahapan yang ketiga Coding adalah tahap pengkodean perangkat lunak dengan paduan alur sistem yang sudah dirancang pada tahap design dari modul per modul Tahapan yang keempat Testing merupakan tahap pengujian sistem agar mendapat feedback dari orang yang telah melakukan pengujian untuk mentukan sistem berjalan dengan normal atau tidak. pembuatan sistem ini dibuat menggunakan bahasa pemrograman PHP dan manajemen database menggunakan MySQL. Untuk meningkatkan pelayanan dan kepuasan terhadap pelanggan, maka toko tersebut melakukan peningkatan pelayanan dengan cara membangun sistem yang dapat mempercepat proses pembayaran sehingga mencegah terjadinya antrian pada saat melakukan pembayaran pada kasir toko sembako tersebut.

Abstract

The Center for Public Health is a functional organizational unit that implements health care that is thorough, integrated, evenly acceptable, and affordable to the community. The purpose of this research is to create an Expert System Application to detect skin diseases in toddlers according to the data in the public health center. The system development method used is the Extreme Programming (XP) method with working stages including planning, design, coding, and testing. The system is designed using Unified Modeling Language (UML) which includes use cases, activity diagrams, and chart classes, the software used is PHP (Hypertext Preprocessor) with MySQL databases and uses the Naïve Bayes and Forward Chaining methods. The end result of the creation of this App is to make it easier for users or the public in detecting skin diseases for toddlers.

Abstract

The advancement of information technology has significantly transformed various aspects of businessoperations, including the small and medium enterprises (SMEs) sector. The implementation of computerizedinformation systems has become a strategic solution to enhance efficiency, accuracy, and speed in businessprocesses. Toko Rudi, a business engaged in the sales of Tripanca mineral water in Baradatu District, WayKanan Regency, still relies on manual systems for transaction recording, inventory management, and salesreporting. This manual approach has led to several challenges, such as transaction delays, a h igh risk of humanerror in data recording, and difficulties in real-time data monitoring. This study aims to design and implement aSales Information System to address these issues and improve operational performance.The system development methodology applied in this research is Extreme Programming (XP), known for itsiterative approach and flexibility in accommodating changing user requirements. The stages include planning,system design using Unified Modeling Language (UML), coding with NetBeans IDE 8.0 and MySQL, andcomprehensive system testing. Data collection was conducted through direct interviews with the owner and staff,observation of operational processes, and literature review related to information system concepts andsupporting technologies.The implementation results demonstrate that the developed information system successfully automates the entiretransaction process, customer data management, mineral water inventory control, and the generation ofaccurate and timely sales reports. The system significantly improves operational efficiency, reduces humanerror, and facilitates data-driven decision-making. Furthermore, the user-friendly interface ensures that userscan quickly adapt to the new system without requiring extensive training.In conclusion, the implementation of the sales information system at Toko Rudi has had a positive andsignificant impact on operational effectiveness. This system can serve as a reference model for other SMEsseeking to adopt information technology to support sustainable business growth and competitiveness in thedigital era.

Abstract

Regional taxes are one of the important sources of regional income to finance the implementation of regional government in the context of serving the community and realizing regional independence. Restaurant tax is one of the regional taxes collected by the Way Kanan Regency Regional Revenue Agency and one of the determinants of the increase in Way Kanan District Original Revenue (PAD). Adapum This research raises the problem of not achieving the Restaurant Tax target in 2023. In this study using Data Mining there are various methods in data mining including the C4.5 algorithm. The C4.5 approach can forecast an increase in restaurant taxes, and the computation of the C4.5 algorithm yields the following results. From the results of calculating the 2018-2022 data above using Microsoft Excel, it is known that Class Recommendations totaling 185 are classified as Yes and No, 0 are classified as Yes but No, Next Class No totaling 65 is classified as No, and 0 Yes is classified as No, with a total data of 250. Microsoft Excel and Google Colab programs have been used to implement the C4.5 algorithm. Implementation of the C4.5 Algorithm has been carried out using Microsoft Excel and Googlel Colab applications. The result is that the description of all formulas and predictive results is simpler than the results of manual calculations through Microsoft excel using the C4.5 Algorithm which has an accuracy of 75%, and then proven by Google Colab with results of 100% accuracy.
