Telkom Klaten https://www.journal.lembagakita.org/index.php/jtik/article/view/3063 <p>The Point of Interest (POI) represents a specific geographic location defined by its coordinates, including longitude and latitude, and holds value as a site of interest or utility. Examples of POIs include tourist attractions, hotels, restaurants, ATMs, pharmacies, health centers, retail shops, gas stations, and other categories integral to modern navigation systems. PT. Telkom Klaten has faced increased demands to conduct POI surveys efficiently, driven by advancements in technology that call for faster and more streamlined processes. A primary challenge in these surveys is the selection of an optimal route that minimizes time, costs, and fuel consumption, given that the company currently relies on manual input in Google Maps to determine distance and travel time. This manual approach may hinder survey efficiency and increase operational costs. To address this, an application employing the Dijkstra algorithm was developed to determine the shortest route effectively. The Dijkstra algorithm, known for selecting edges with minimal weight to connect sequential nodes, requires defined origin and destination points, thereby generating the most efficient route between them. This study applies the Dijkstra algorithm to optimize survey routes by modeling them as graph-based routes, aiming to identify the shortest and most efficient paths between multiple POI locations. The findings indicate that the Dijkstra algorithm significantly reduces travel distance and time, thereby achieving notable savings in fuel and operational time for POI surveys.</p> Erlina Kumala Kusumawati, Dwi Hartanti, Tri Djoko Santosa Copyright (c) 2024 Erlina Kumala Kusumawati, Dwi Hartanti, Tri Djoko Santosa https://creativecommons.org/licenses/by-nc/4.0 https://www.journal.lembagakita.org/index.php/jtik/article/view/3063 Mon, 11 Nov 2024 00:00:00 +0700 Implementasi Algoritma Apriori Pada Aplikasi Penjualan Buah Berbasis Web https://www.journal.lembagakita.org/index.php/jtik/article/view/2971 <p>This research aims to implement the Apriori algorithm in a web-based fruit sales application to discover consumer purchasing patterns and provide appropriate product recommendations.

The quality of beef determines the nutritional value and taste of the processed meat product. However, the quality of beef can decrease over time, especially if it is not stored properly. Therefore, identifying the condition of beef is crucial to ensure that consumers get safe and quality products. The use of the HSV (Hue, Saturation, Value) color space for beef classification is an interesting method to research. The HSV color space is closer to human perception of color compared to the RGB color space, making it more effective for image analysis in the context of visual quality assessment of meat. In this study, researchers used HSV space extraction to classify fresh beef and bad beef. This research aims to develop a method for classifying fresh, medium and rotten beef using the HSV color space. This research produces accurate extraction results with appropriate classification of fresh and bad beef.</p> Dadang Iskandar Mulyana, Veri Arinal, Feri Akbarulloh Copyright (c) 2024 Dadang Iskandar Mulyana, Veri Arinal, Feri Akbarulloh https://creativecommons.org/licenses/by-nc/4.0 https://www.journal.lembagakita.org/index.php/jtik/article/view/3129 Mon, 11 Nov 2024 00:00:00 +0700 Implementasi Perancangan Digital Marketing pada Instagram Rumah Makan Bebek Bakar A'Yayo https://www.journal.lembagakita.org/index.php/jtik/article/view/3111 <p>This research explores how improving Instagram marketing strategies can boost consumer interest for Bebek Bakar A'Yayo, a restaurant in Bandung.
