Abstract

Technological advances are always developing, especially in the field of utilizing computers both in terms of hardware and software. The use of technology in sales activities is expected to increase the number of sales and profits. Fauzan Motor store in its business activities still does not have an integrated system so that in running its business there are still many shortcomings such as the slow delivery of new products to customers, so that customers are only glued to one product. Lack of information obtained by customers causes low sales. Mala conducted this research for the Fauzan Motor store in increasing sales using the up selling method. The system built is a computerized sales system development. The system works by comparing the product that has been selected by the customer with similar products, such as a brand, category with a higher price and quality, one level above the product chosen by the customer. Sales information system development technique using the System Development Life Cycle (SDLC). The programming language used is PHP 7 which is based on Object Oriented Programming (OOP) and JavaScript. Structuring objects using Bootstrap 5 on web pages to make them more informative. This research produces a sales application system that can increase sales turnover. Each customer is given recommendations for several available products so that consumers can choose products according to quality and affordable prices. So this research is very helpful in increasing sales and is more effective in increasing store revenue.

Abstract

Sistem Pendukung Keputusan (SPK) merupakan alat yang dapat membantu pengambil keputusan dalam membuat keputusan tentang suatu masalah dengan lebih cepat dan akurat. SPK pada dasarnya dapat di implementasikan pada sebuah program komputer yang digunakan untuk menganalisis dan menyajikan data sehingga dapat membuat keputusan dengan lebih mudah. SPK dapat dijadikan sebagai sebuah aplikasi yang dapat menyajikan informasi secara cepat dan akurat. Penelitian ini bertujuan untuk melakukan analisis dengan menggunakan konsep SPK dalam melakukan penilaian terhadap karyawan PT Tiga Putra berdasarkan kinerja metode Analytic Hierarchy Process (AHP). Permasalahan yang terjadi faktanya bahwa penilaian karyawan masih dilakukan secara manual sehingga menyebabkan terjadinya manipulasi dan kesalahan data. Proses analisis dengan metode AHP dilakukan dengan beberapa langkah yakni menyusun hirarki, menentukan prioritas antar kriteria, hingga mengukur konsistensi perbandingan berpasangan kriteria dan masing-masing subkriteria. Kinerja metode AHP nantinya diharapkan dapat membantu pihak HRD pada PT Tiga Putra dalam penilaian terhadap karyawan sehingga kebijakan perlakuan terhadap karyawan bisa lebih cepat, tepat, dan akurat. Hasil penelitian ini menyajikan bahwa kinerja AHP mampu melakukan penilaian karyawan di PT Tiga Putra dengan sajian lebih efektif dan efesien. Hasil ini dapat dijadikan solusi alternatif bagi pihak PT Tiga Putra dalam melakukan penilaian terhadap karyawan

Abstract

Imagery on edge detection is a process that will display the edges of an image. Basically, edge detection is one of the techniques for the analysis of image quality in the spatial domain and is also one of the initial process in digital image processing. Edge detection serves to detect the border line of an object contained in the image. This study aims to identify and recognize face pattern objects in the capture zoom image. To perform face identification begins with collecting image data, image processing, image edge detection, thinning of the image, and identification process using the template matching method. The method used in edge detection uses 3 methods, namely Sobel, Roberts and Prewitt which are gradient operators to detect edges in facial images. The dataset used is image capture zoom. The trial was carried out in two stages, namely the identification of the face shape and the identification of the edges of the face. The conclusion of the study is that the Roberts operator is the operator that finds the least edge patterns in facial images than the other two operators, namely Prewitt and Sobel. Meanwhile, the Sobel operator produces edge patterns that are better in quality and quantity than using the Roberts and Prewitt operators.

Abstract

The annual death toll from heart disease is 17.5 million people. Currently, heart disease is a prevalent condition that kills a lot of people and shortens people's lives. Life is based on the work of the heart, since the heart is a much-needed part of our body where life is impossible. Heart disease affects heart function and can lead to death or annoy the patient before deathThe use of contemporary medical imaging methods like computed tomography (CT), ultrasound, and magnetic resonance imaging (MRI), as well as X-rays, is now commonplace. These methods enable non-invasive qualitative and quantitative assessment of the anatomical structure and function of the heart and support diagnosis, disease monitoring, treatment planning, and prognosis. The purpose of this study is to find heart problems in patients. The data used in this study were chest X-rays of patients with normal heart conditions and chest X-rays of abnormal heart patients obtained from the kaggle website. Segmentation techniques are used to process these cardiac images. Segmentation is the process of separating between an object and another object or between objects and the background contained in an image. Then the calculation of the area of the heart area is carried out using the extraction of morpological and regional features method characteristics with an algorithm that has been developed. The results of this study can identify heart defects through the process of measuring the area of the heart normal and abnormal. So that it produces a good accuracy rate of 85%. This segmentation technique is proven to be very good so that it can be a medical reference to perform further medical actions against abnormalities in the heart.

Abstract

Sistem Pakar secara umum adalah sistem yang berusaha mengadopsi pengetahuan manusia ke komputer, agar komputer dapat menyelesaikan masalah seperti yang biasa dilakukan oleh para ahli.Certainty Faktor merupakan sebuah metode yang dapat melakukan identifikasi dengan memberikan keluaran hasil dalam bentuk persentasi kepastian yang memberikan kepastian untuk menjelaskan hasil penalaran terhadap sebuah pernyataan. Pada Kerusakan Ban faktor-faktor yang menyebabkannya, diman terbagi dalam beberapa tipe kerusakan Retak-retak, Aus Tidak Merata, Ban Me-ledak, Cut Burst, Spot Wear dan Atread Chipping. Sistem Pakar menggunakan metode Certainty Factor yang mana pada penelitian ini Certainty Factor digunakan untuk menetukan besarnya kepercayaan, yang diterapkan dalam penelitian ini untuk menentukan berapa persentase kerusakan yang terjadi. Hasil yang didapatkan dari Sistem Pakar ini adalah berupa kerusakan Ban. Sistem Pakar ini diimplementasikan menggunakan bahasa pemrograman PHP.
