Abstract

Karanganyar Regency has significant potential in the tourism sector, especially nature tourism. However, the abundance of destination choices often makes it difficult for tourists to determine places that match their preferences. Currently available information is general and cannot be tailored to the specific needs of each user, making the decision-making process less efficient. This research proposes a knowledge-base recommendation system designed to assist users in selecting tourist destinations in Karanganyar according to their preferences. This system utilizes five main attributes: category, location, ticket price, rating, and facilities. System development was carried out using the Waterfall method, which includes requirements analysis and system design stages. User input is processed by matching it against the tourism data knowledge base using specific rules, and similarity calculations are performed to measure the degree of resemblance between user preferences and available tourism data. Based on similarity calculation results for 10 nature tourism data points, the system successfully recommended a destination with the highest similarity value of 0.991, namely Bukit Mongkrang, which best matched the user's selected criteria. Bukit Mongkrang met the user's desired criteria, being located in Tawangmangu, classified as nature tourism, having a mid-range ticket price, a rating 0.2 higher than the user's preference, and providing key facilities sought by the user. The results of this knowledge-base recommendation system modeling can serve as a reference for developing similar systems in the tourism field.

Abstract

Food is a fundamental human need that plays a crucial role in supporting health. For housewives, cooking is a daily routine in preparing nutritious meals for their families. In the digital era, technology simplifies recipe searching, but the abundance of available recipes often makes it difficult for users to find ones that match their available ingredients. To address this issue, this study develops a recipe recommendation system based on content-based filtering. The dataset was collected from cookpad.com and includes recipe names, ingredients, cooking duration, and cooking instructions. The system is designed using a content-based filtering approach and cosine similarity to measure the relevance between user input and existing recipe data. Users simply input ingredients, seasonings, or types of dishes they have, and the system provides relevant recommendations. Testing results show that the system can accurately identify and recommend recipes based on keywords, including specific cases such as "Soto Ayam Bening." The recommendations generated are reasonably accurate and assist users in selecting the most suitable recipes according to their needs. This system is expected to offer a practical solution for users in determining appropriate meal choices based on the ingredients available at home

Abstract

Hujan merupakan fenomena turunnya air ke permukaan bumi. Hujan juga merupakan bagian dari siklus biologis dan terbentuk dari penguapan air laut dan air darat yang naik dari permukaan bumi, dibawa ke atmosfer oleh angin, kemudian mengembun dan akhirnya jatuh ke daratan atau permukaan. Pergantian musim yang tidak stabil mengakibatkan cuaca sulit untuk diprediksi. Kondisi ini menjadi masalah utama bagi masyarakat yang sedang menjemur pakaian terutama pada saat cuaca buruk. Biasanya jika hendak berpergian, pakaian yang basah akan dijemur didalam rumah agar tidak terkena hujan. Hal tersebut mengakibatkan pakaian lembap menjadi berbau serta membutuhkan waktu yang lama agar dapat kering.Dengan adanya permasalahan tersebut, diperlukan sebuah rancangan jemuran otomatis yang dapat menggerakan jemuran apabila terdeteksi turun hujan maupun kondisi cuaca tertentu. Jemuran otomatis ini dikembangkan dengan metode prototyping menggunakan Node MCU, sensor hujan, sensor cahaya, sensor DHT22, motor servo dan menggunakan aplikasi Blynk untuk memantau nilai masing-masing sensor serta menggerakkan jemuran secara manual.  Berdasarkan hasil pengujian, jemuran akan bergerak ke dalam apabila sensor hujan mendeteksi adanya air dan sensor cahaya mendeteksi cahaya matahari menjadi redup. Lalu, jemuran juga akan bergerak ke dalam apabila sensor cahaya mendeteksi cahaya matahari menjadi redup serta sensor DHT22 mendeteksi suhu dan kelembaban yang semakin rendah. Jemuran akan bergerak ke luar apabila cahaya semakin terang, suhu dan kelembaban meningkat serta sudah tidak ada air yang terdeteksi pada sensor hujan. Jemuran juga dapat digerakkan secara manual menggunakan aplikasi Blynk. Dapat ditarik kesimpulan, bahwa parameter untuk menggerakkan jemuran otomatis, bukan hanya terletak turunnya hujan, namun intensitas cahaya, suhu dan kelembaban juga merupakan parameter untuk menggerakan jemuran tersebut.

Abstract

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.

Abstract

Subarachnoid Hemorrhage (SAH) represents a critical medical condition resulting from bleeding in the subarachnoid space, typically due to the rupture of an aneurysm or trauma. Timely identification is vital to avoid long-term neurological impairment. This research assesses the efficacy of U-Net compared to Attention U-Net for the segmentation of SAH in brain CT images, aiming to determine if attention mechanisms enhance segmentation precision. The motivation for this comparison stems from the clinical difficulty in identifying subtle or low-contrast hemorrhagic areas that traditional architectures like U-Net might miss; in contrast, attention-based models are constructed to capture spatial details more proficiently. Both architectures were evaluated using a publicly available SAH CT dataset and assessed on metrics including Dice Score, Intersection over Union (IoU), Precision, Recall, and F1 Score. Attention U-Net outperformed U-Net with higher scores of Dice (0.896) and IoU (0.877), whereas U-Net excelled in precision. Visual assessments also indicated that Attention U-Net was superior in delineating diffuse hemorrhagic regions. These findings advocate for the incorporation of attention mechanisms to enhance segmentation accuracy and clinical relevance in neuroimaging

Abstract

Traditional physical door locks have various limitations, including the risk of loss, unauthorized duplication, and the inability to log access in real time. In a dynamic work environment such as PT Ekasa Teknologi Nusantara, this poses potential security risks to valuable company assets. A more flexible, efficient, and digitally monitored security system is therefore required. This study aims to design an Internet of Things (IoT)-based Smart Door Lock system capable of automatically recording and managing access. The method used involved observation of employee access patterns and the Agile software development approach, consisting of planning, design, development, testing, deployment, review, and launch phases. The system was developed using an ESP32 microcontroller, RFID module, and solenoid lock, all integrated with a user interface for managing access data. Testing results showed that the system can log entry activity in real time, send notifications, and provide management with flexibility in granting or revoking access rights. Thus, the system enhances company asset security, reduces reliance on physical keys, and offers an adaptive digital solution for workspace access control. The system also has potential for further development to meet organizational needs.
