Abstract

Petra Christian University has various services for general information about university majors and student admissions, such as social media and WhatsApp. However, these services still limited by number and working time of operators as human. Therefore, with this chatbot, information about PCU can be found anytime. Chatbot Study by S. C. P & Afrianto needs method to match chatbot question with the dataset. This thesis uses two methods, namely kNN (k-Nearest Neighbor) and HMM (Hidden Markov Model) to solve these problem. In this chatbot, it will try to combine and compare these two methods, and see if it can produces answers that can be understood and in accordance with various difficulty questions given. The kNN is used as a classification for questions given to chatbot which approximately match with questions on the chatbot’s knowledge base. HMM is used to assemble answer words from the selected knowledge base. Chatbot’s answers will be tested in terms of validity of the answers by two respondents (Public Relation and Admission staff) also the length of time it takes to produce answers. The results of the chatbot with kNN has an accuracy of 64.44% (45 questions), with average system runtime of 0.08 seconds. While the results of chatbot with kNN-HMM produces random and irregular answers, with average system runtime of 0.12 seconds, cause by HMM which is a probability based method.

Abstract

Internet helps human by making various information from many online news platform accessible. But nowadays, there are a lot of news that can be accessed in different online news platform and needs to be categorized. The news that can be accessed in some of the sources don’t have high credibility about an event, because the publishers use false and misleading information to push their agendas. So in order to check the credibility of an event, it is needed to also read from other sources and not only from 1 source. However, this is not effective because the reader has to look for another news source with different URL address. In this research scraping will be done to retrieve the news that are available in a news platform. After the scraping process is done, the news will be classified to determine the category of the news. The method that will be used is Bidirectional Encoder Representations from Transformers. From the testing of this research, the news can be retrieved and classified. The testing with a pre-trained model indobenchmark /indobert-base-p1 get a very good result where the accuracy reaches 87.548%.

Abstract

There are two important aspects that will play important roles in future manufacturing systems: changeability and human-machine collaboration. The first aspect, changeability, concerns with the ability of production tools to reconfigure themselves to the new manufacturing settings, possibly with unknown prior information, while maintaining their reliability at lowest cost. The second aspect, human-machine collaboration, emphasizes the ability of production tools to put themselves on the position as humans’ co-workers. The interplay between these two aspects will not only determine the economical accomplishment of a manufacturing process, but it will also shape the future of the technology itself. To address this future challenge of manufacturing systems, the concept of Cognitive Factory was proposed. Along this line, machines and processes are equipped with cognitive capabilities in order to allow them to assess and increase their scope of operation autonomously. However, the technical implementation of such a concept is still widely open for research, since there are several stumbling blocks that limit practicality of the proposed methods. In this paper, we introduce our method to achieve the goal of the Cognitive Factory. Our method is inspired by the working mechanisms of a human’s brain; it works by harnessing the reasoning capabilities of cognitive architecture. By utilizing such an adaptive reasoning mechanism, we envision the future manufacturing systems with cognitive intelligence. We provide illustrative examples from our current research work to demonstrate that our proposed method is notable to address the primary issues of the Cognitive Factory: changeability and human-machine collaboration.

Abstract

Human-Computer Interaction (HCI) nowadays mostly uses physical contact, such as people using the mouse to choose something in an application. However, there are certain problems that people face in using conventional HCI. The research tries to overcome some problems when people use conventional HCI using the computer vision method. The research focuses on creating and evaluating the object detection model for classifying hand symbols. The research applies the fifth version of YOLO with the architecture of YOLOv5m to classify hand symbols in real time. The methods are divided into three steps. Those steps are dataset creation consisting of 100 images in each class, training phase, and performance evaluation of the model. The hand gesture classes made in the research are ‘ok’, ‘cancel’, ‘previous’, ‘next’, and ‘confirm’, the dataset is made by the researchers custom. After the training phase, the validation results show 93% for accuracy, 99% for precision, 100% for recall, and 99% for F1 score. Meanwhile, in real-time detection, the performance of the model for classifying hand symbols is 80% for accuracy, 95% for precision, 84% for recall, and 89% for F1 score. Although there are differences, it still acceptable for the research and can be improved in future research.

Abstract

Urban Farming adalah teknik bercocok tanam di lingkungan perkotaan dengan memanfaatkan area, seperti halaman rumah, taman, atau bahkan atap bangunan. Untuk mengoptimalkan manfaat dari urban farming, perlu tata kelola yang baik dan terkontrol mulai dari proses awal persiapan, penanaman, perawatan sampai panen dan pasca panen. Di Surabaya ditemukan urban farming berupa kebun hidroponik yang dimiliki oleh KRPL Tambakrejo Surabaya yang tidak berfungsi dengan baik. Melalui kegiatan pengabdian masyarakat dengan metode ABCD (Asset Based Community Development), dilakukan upaya pemberdayaan dan perbaikan dengan mentransformasi kebun hidroponik konvensional mereka menjadi kebun hidroponik cerdas. Metode tersebut diimplementasi mulai dari identifikasi permasalahan yang dihadapi KRPL Tambakrejo, yaitu kesulitan pasokan air bersih, serangan hama tikus, sumber listrik yang terbatas dan cara pemasaran produk yang kurang optimal. Proses transformasi dilakukan melalui revitalisasi kebun hidroponik konvensional menjadi kebun hidroponik cerdas berbasis IoT dan bertenaga surya. Dari hasil analisa setelah dilakukan transformasi tersebut, kebun hidroponik milik KRPL Tambakrejo bisa menghasilkan keuntungan minimal Rp 4.032.000 pertahun. Selain sangat hemat energi listrik dan dapat dipantau secara langsung lewat internet, kebun hidroponik tersebut saat ini juga sudah bebas dari hama tikus.

Abstract

Revolusi industri 4.0 yang sedang berkembang pesat telah mempengaruhi perkembangan pendidikan. Untuk mempersiapkan mahasiswa menghadapi era industri 4.0, laboratorium elektronika di Universitas Kristen Petra telah membuat modul berdasarkan kebutuhan industri saat ini. Pemisahan dua produk telah menjadi suatu kebutuhan dalam industri manufaktur. Saat ini, pemisahan produk telah beralih dari metode manual menjadi otomatis guna meningkatkan efisiensi. Sistem yang akan dibuat akan menggunakan robot universal 3 CB-Series untuk mengambil produk dari konveyor. Sistem ini juga akan menggunakan web camera sebagai penglihatan komputer dengan menggunakan OpenCV untuk mendeteksi produk, serta encoder untuk melacak pergerakan serta kecepatan konveyor. Berdasarkan uji coba yang dilakukan, sistem berhasil memisahkan produk berdasarkan rasa dengan membedakan warna dari kotak produk. Sistem ini dapat beroperasi dengan baik pada kecepatan konveyor sebesar 0,0708 meter/detik dan intensitas cahaya antara 1,36 hingga 1,72 lumen, dengan tingkat keberhasilan mencapai 99%. Jika terdapat permen yang masuk ke dalam sistem namun warnanya tidak terdaftar dalam program OpenCV, produk tersebut tidak akan terdeteksi.

Abstract

Some elders prefer to live independently rather than in a nursing home. However, they need to be assisted because of health and safety reasons. We developed an integrated system consisting of a smart home, a mobile robot, and a wearable device, using message queuing telemetry transport (MQTT) protocol to communicate with each other. The smart home can be monitored and controlled via a mobile application. We use the telepresence robot equipped with a light detection and ranging (LIDAR) sensor to perform simultaneous localization and mapping (SLAM) and autonomous navigation. The wearable device application is used to detect older adults' heart rate, the steps taken, and the burnt calories. We also add pose detection and location estimation using a depth camera powered by an efficient deep-learning algorithm. We also developed an Android application as a dashboard that monitors and controls all system components. Our system can facilitate communication between its various components.
