Abstract

Masalah pendistribusian produk yang optimal dari sumber ke tujuan menjadi sangat kompleks jika terdapat banyaksumber (sources) dan banyak tujuan (destinations). Tujuanpenelitian ini adalah menentukan jumlah barang yang akan didistribusikan dengan memenuhi jumlah permintaan danpersediaan tercukupi dengan ongkos seminimal mungkin. Metode-metode transportasi sebelumnya telah mampu menghasilkan nilai fisibel awal yang optimal untuk masalahtransportasi. Untuk menguji optimalitas metode, dalampenelitian ini akan dilakukan komparasi dengan sebuah metodetransportasi baru yang disebut Allocation Table Method (ATM)dengan diberikan sebuah implementasi kasus di instansi. Hasilpenelitian membuktikan bahwa dengan menggunakan Allocation Table Method (ATM), solusi yang dihasilkan optimal dan biayatransportasi lebih minimal.

Abstract

The accelerated development of e-commerce has been a concern for business people. Business people should be able to gain customer interest in a variety of ways so that their companies can compete with others.  Analyzing click-flow data will help organizations or firms assess customer loyalty, provide advertising privileges, and develop marketing strategies through user interests. By understanding consumer preferences, clickstream data analysis may be used to determine who is participating, assist companies in evaluating customer contentment, boost productivity, and design marketing strategies. This research was performed by defining experimental user interests using Dynamic Mining and Page Interest Estimation methods. The findings of this analysis, using three algorithms at the pattern discovery page, demonstrated that the Decision Tree method excelled in both methods. It indicated that the operational performance of the Decision Tree performed well in the assessment of user interests with two different approaches. The findings of this experiment can be used as a proposal for researching the field of web usage mining, collaborating with other approaches to achieve higher accuracy values.

Abstract

Visitor interaction with e-commerce websites generates large amounts of clickstream data stored in web access logs. From a business standpoint, clickstream data can be used as a means of finding information on user interest. In this paper, the authors propose a method to find user interest in products offered on e-commerce websites based on web usage mining of clickstream data. In this study, user interest was investigated using the PIE approach coupled with clustering and classification techniques. The experimental results showed that the method is able to assist in analyzing visitor behavior and user interest in e-commerce products by identifying those products that prompt visitor interest.

Abstract

Transportation is the process of distributing products from source to destination. Transportation problems are special cases of network optimization method where the numbers of goods distributed from sources to destinations are optimized thereby minimizing transportation costs. The increasing number of sources and destinations results in complex calculations of the distribution process. The methods to find optimal solutions in determining the number of goods distributed with the aim of minimizing costs have been proposed. Comparative methods have been carried out and obtain optimal solutions. The result shows that the algorithm of the Allocation Table Method has shown better performance compared to previous methods such as Least Cost Method, Vogel Approximation Method dan North West Corner Method. Yet, a more complex transportation network needs a calculation method to seek for solutions. The aim of the study was to implement the algorithm of the Allocation Table Method as a method to seek solutions in a system designed to support problem-solving. The tryout conducted on several cases has shown that the Allocation Table Method is a leading method in finding optimal solutions for transportation problems involving multi-sources and multi destinations.

Abstract

Augmented Reality applications have become one of the technologies that has developed rapidly in the last few decades. This technology will later be used to help solve challenges in the education sector. Common problems that occur in the world of education usually lie in learning methods. Teachers usually only use classical teaching aids and do not provide opportunities for students to explore further with existing media. Therefore, an Augmented Reality based application is used. Augmented Reality is a technology that combines digital information such as images, videos or 3D models with the user's environment in real time. Application design as Android-based learning media. This Augmented Reality application will later help students' learning process. The application runs on Android-based smartphones. The contents of this application will be a 3D model, detailed information about the animal. As well as audio that will explain the details of the animal. It is hoped that this application can facilitate students to learn about animals, especially based on types of food. In order to determine the effectiveness of the application being developed, a pretest and posttest were carried out. The results show that at the posttest students had better abilities compared to before

Abstract

Augmented reality (AR) provides intriguing opportunities to enhance the learning experience by merging the real world with interactive virtual elements. This research aims to develop an interactive learning application using augmented reality technology to introduce human body anatomy in a more engaging manner. The development method follows the waterfall system with stages of needs analysis, design, implementation, and testing. The researcher employs UML models, flowcharts, and wireframes in the system analysis and design. The application is built on the Unity platform with AR plugins such as Vuforia and ARCore. The AR model utilized in this development involves marker-based tracking and markerless tracking. Testing is conducted to measure the success level of the application, employing black box testing methods to ensure the application's usability without issues. The outcome of this research is an Android-based human body anatomy learning application utilizing augmented reality technology, with the expectation that it will facilitate a better understanding of the human anatomy system.

Abstract

Kota Yogyakarta dikenal sebagai kota pelajar. Dengan sebutan“Kota Pelajar” sesuai dengan banyaknya perpustakaan yang ada di Kota Yogyakarta, termasuk Perpustakaan Kota Yogyakarta[1]. Kota yogyakarta juga merupakan kota budaya. Karena banyak pelajar yang datang dari luar kota, para mahasiswa membutuhkan tempat kost yang dapat mereka tinggali saat masih berkuliah. Biasanya mahasiswa ingin kost yang terletak paling dekat dengan kampus untuk menghindari biaya transportasi yang mahal bila tidak mempunyai kendaraan sendiri. Permasalahan yang ada adalah efektifnya memberikan informasi yang komprehensif sesuai kebutuhan mahasiswa. lokasi penyedia tempat kost berada di wilayah kampus 1 UTY. secara finansial. Alur sistem ini memungkinkan mahasiswa untuk mencari tempat kost perempuan dan tempat kost laki-laki, menambahkan informasi data kost perempuan dan kost laki-laki, mencari kost berdasarkan nama yang dicari, dan menampilkan hasilnya ditambahkan ke daftar pensiun. Sistem ini menggunakan metode waterfall. Pengembangan sistem menggunakan alur kehidupan sekuensial linier atau klasik, sedangkan  pengujian sistem menggunakan black box dengan fokus pada fungsionalitas dan kemudahan penggunaan. Hasil  penelitian yang digunakan untuk membuat mencari dan pemesanan kost aplikasi diharapkan dapat memudahkan dalam mengiklankan tempat kost di wilayah Universitas Teknologi Yogyakarta dan menemukan tempat kost terdekat.

Abstract

DUKCAPIL services often face obstacles in receiving services manually, which results in a lack of efficiency in community services. The development of an integrated service system based on websites and mobile applications using API technology is a solution in improving efficiency in population and civil registration document services. Development is carried out using API technology as a link between the system and the application. Tests conducted using the System Usability Scale (SUS) by 56 respondents, resulted in a score of 70.08. The score indicates that the system can facilitate online document services as expected. User satisfaction testing can show that the application of service technology through website systems and mobile applications with API technology can provide significant technological support to DUKCAPIL so that it is expected to increase effectiveness and efficiency in community services.
