Abstract

Indonesia is famous for its diversity from ethnicity, religion, culture, customs, to traditional buildings or commonly called traditional houses. There are many traditional houses in Indonesia. Each region or place has its own traditional house or building. To preserve this traditional house, a model such as Ontology is needed. The ontology knowledge base is an appropriate method used to represent information. In this project, the ontology model was built using the Protégé ontology development tool. We use the method of METHONTOLOGY in the development of the ontology model where this method describes each step-in detail. The ontology model built has 9 classes, 4 object properties, 1 data properties, and 80 individuals. The testing process in the development of the ontology model by performing SPARQL queries.

Abstract

This research aims to develop an air quality monitoring system based on the Open Meteo API and OpenStreetMap API using the Software Development Life Cycle (SDLC) approach. By utilizing latitude and longitude data, users can see the air quality index (AQI) at a location with a default forecast for one day every hour. Users also have the option to configure the location and number of days for the forecast. Through trials, this website succeeded in determining AQI values based on user configuration. In addition, this system uses color as a visual representation of AQI categories based on united states air quality index standards, making it easier for users to understand the level of health risk. The development of this system involves the SDLC method to ensure a smooth development process from design to implementation. Apart from increasing the accuracy of AQI mapping, the use of the OpenStreetMap API also allows location identification based on geographic coordinates. Overall, this research contributes to the understanding and monitoring of air quality with an approach that is easy to access and understand for users. Keywords: aqi, api, open meteo, vercel, github

Abstract

In a world driven by advances in technology, society uses technology more than ever to help support them in many ways. A few of the common ones are to have a business with information systems offline to help achieve their business goals and to have a website so that their business would have a presence online and can be reached globally by the international audience. With every aspect of modern technology, be it offline or online, the user interface and user experience plays a critical role in how the new technology can be usable and adaptable by users of the businesses, and their customers. In the online space, the user experience should be perfected in order to make the website more valuable, accessible, usable, desirable, trustable, and credible to help the user feel more comfortable using the website. This journal will cover how Google analytics can be used to optimize the user experience (UX) to increase the conversion of a website. In order to analyze & enhance the UI and UX of a website, one needs to use both a heuristic approach or known as the rule of thumb approach coupled with a data analysis/data-driven approach. For the data analysis approach to work we would need to sample user traffic data of the website, and identify behavior trends, findings and make conclusions. There are many ways to attract user traffic to a website. Email channel, direct, organic social, organic search, and paid search and paid social are just a few of those many ways. The fastest way out of these options would be to attack traffic via ads placements or paid search ads and paid social ads which can used as a source of the traffic for the data analyses to function. that will be covered in this study. Once traffic is available, Google Analytics can be used to analyze traffic in order to improve the user experience of the website. This journal has proven that google analytics can help the business to optimize the UX of our website. The goal of this business is to get the user to click the WhatsApp button and communicate with the owner. We get 11 users that click the WhatsApp button in January which is before the website UX is upgraded, 16 users in February when the new version design is launch, and the new one in March which has 25 users to click the WhatsApp button on website. This have been proven that the conversion rate of user clicking WhatsApp button is after the UX design have been launch is higher than before the website used the UX design.

Abstract

Tokopedia has an average number of visitors per month which is 149.67 visitors. In addition, the Tokopedia application has been downloaded by more than 100 million users with 6.34 million reviews and received a rating of 4.7 out of 5. This study aims to classify the positive and negative reviews of the Tokopedia application on the Google Playstore. The results of the 2000 test data testing obtained 842 positive reviews and 1158 negative reviews. This means the percentage for positive reviews is only 42.1%, in contrast to negative reviews of 57.1%. The performance generated in this test against 2000 testing data is 96.19% accuracy value, with a precision value of 1. While in Class Recall the resulting value is 93.45% (positive class: negative). Then for the AUC value is 0.975.

Abstract

Modul ESP8266 dan sensor ultrasonik HC SR04 akan digunakan dalam penelitian ini untuk membangun mekanisme pemberian pakan ikan otomatis. Sistem ini diciptakan untuk melacak stok pakan dan mengingatkan pengguna. Pembuatan alat pemberian pakan otomatis yang dapat meningkatkan produktivitas budidaya ikan adalah tujuan utamanya. Selain itu, penelitian ini menempatkan fokus pada pemantauan dan pengendalian akuarium berbasis IoT. Kejernihan air dipantau menggunakan sensor kekeruhan, sedangkan stok makanan ikan dipantau menggunakan sensor ultrasonik. Aplikasi Blynk dapat digunakan dengan gadget ini untuk memantau dan mengatur kondisi akuarium, termasuk mengatur waktu pemberian makan ikan secara otomatis. Studi ini memberikan kontribusi yang signifikan terhadap kemajuan teknologi otomasi serta peningkatan administrasi dan pemeliharaan akuarium. Sistem pemberian pakan ikan otomatis yang dikembangkan oleh penelitian ini berfungsi 100% sepanjang waktu. Temuan pengujian menunjukkan ketidakakuratan 3,26% pada nilai suhu termometer dan sensor DS18B20. Dibandingkan dengan pengukuran manual, akurasi deteksi ketinggian air Sensor Ultrasonik berkurang 4,61%. Pengujian relai aplikasi Blynk berhasil sepenuhnya. Hasil ini menunjukkan betapa bergunanya alat ini untuk memantau dan meningkatkan hasil budidaya ikan akuarium.

Abstract

Nowadays, people tend to search for goods or services through their mobile device using an electronic marketplace. In Bali, a rental business for tourist, weekend events, and other events grow rapidly. This business provides services that rents various kinds of car such as innova, alphard, alya, and others that are commonly used in weekend events. However, unfortunate for rental service entrepreneurs who have high prospects, many of them are using the traditional method of marketing and sales such as word-of- mouth. Moreover, many of them not catching up with the current development of the rental car. By listing the services on the rental, easier for the customer to find the car they want that fit their needs and budget. Also, by utilizing rental car will save the customer time, because the customer can just search, compare, and book to rent car without leaving home. The purpose of this research project is to create a mobile- based application of market place that accommodates entrepreneurs renting car. Our purposed mobile-based rental uses the prototyping method to build this mobile-based application

Abstract

Pop Punk – merupakan salah satu subgenre dari musik punk yang menggabungkan elemen-elemen dari musik pop dengan musik punk. Musik pop punk identik dengan tangga nada yang disadur atau turunan dari musik pop, namun untuk tempo dan gaya bermain mengikuti musik punk yang identik dengan tempo cepat dan suara gitar yang ramai. Pop punk telah mengalami naik turun popularitas seiring dengan berjalannya waktu, namun musik pop punk selalu dapat berkembang dari waktu ke waktu sehingga musik ini dapat diklasifikasikan dalam dua era secara garis besar yaitu oldschool dan modern berdasarkan gaya permainannya. Penelitian ini membahas klasifikasi musik pop punk berdasarkan kedua era tersebut (oldschool dan modern) dengan metode K-Nearest Neighbor menggunakan 5 fitur musik (danceability, energy, key, speechiness, dan valence). Nilai akurasi klasifikasi yang dihasilkan penelitian ini adalah 76%.
