Abstract

Bidang pertanian adalah salah satu ujung tombak untuk menopang kehidupan manusia. Meskipun demikian, aktivitas mengakses informasi pertanian melalui media internet masih merupakan hal yang baru bagi petani. Terlihat dari kurangnya akses petani terhadap informasi mengenai pertanian. Hal inilah yang mendorong PT Agro Lestari Merbabu, untuk membantu mitra dalam menangani masalah "“ masalah pada tanaman yang mereka budidayakan. Bisa dengan mendapatkan solusi dari informasi yang dihadirkan pada aplikasi dan konsultasi kepada ahli tani. Penelitian ini bertujuan merancang antarmuka pengguna (UI) dan pengalaman pengguna (UX) sesuai dengan kebutuhan pengguna serta menghadirkan desain antarmuka yang baik untuk memberikan kepuasan kepada pengguna.

Abstract

Artificial intelligence (AI) has recently empowered drones to support smart city apps and recognize on-the-ground objects or events. Various pre-trained backbones are available to develop object recognition models, and some of them could boost the models’ accuracy. Consequently, it becomes difficult for practitioners to select a suitable backbone as a feature extractor during recognition model development. Hence, this research aims to provide a benchmark examining the performance of three popular backbones in supporting recognition models using images captured by drones as the dataset. This research used the UAV-AUAIR dataset and compared three deep learning backbone architectures as the feature extractor, namely YoloV8_s, EfficientNetv2_s, and CSP_DarkNet_l. The head part of each selected backbone was replaced with YoloV8Detector architecture, provided by Keras-CV, to perform the inference tasks. The models generated during training were evaluated against four measurement methods: loss function, intersection over union (IOU), across-scale mean average precision (mAP), and computational performance. The results showed that the model generated using EfficientNetv2_s backbone outperformed the others in most criteria, except the computational performance and detecting small objects, which was won by YOLOV8_s and CSP_Darknet_l, respectively. Thus, EfficientNetv2_s and CSP_DarkNet_l can be considered if app development concerns accuracy. Meanwhile, YoloV8_s is far better when computational performance is essential, as its prediction time achieved 0.8 seconds per image. This study is essential as a reference for practitioners, particularly those who want to develop an object-recognition model based on a pre-trained backbone.

Abstract

Bahasa isyarat dengan menggunakan gerakan tangan biasanya dilakukan oleh tuna rungu dan tuna wicara. Bahasa isyarat yang digunakan di Indonesia adalah SIBI (Sistem Isyarat Bahasa Indonesia). Namun, penggunaan bahasa isyarat tangan tidak selalu di mengerti oleh manusia normal sehingga dibutuhkan perangkat tambahan yang dapat mempermudah dalam menerjemahkan suatu isyarat. Perangkat tambahan yang dikembangkan dalam penelitian ini melibatkan teknologi visi komputer deep learning sehingga menghasilkan tools untuk menerjemahkan bahasa isyarat tangan. Dalam penelitian ini, gambar isyarat tangan di capture menggunakan webcam kemudian dilakukan pre-processing dengan mengubah gambar ke dalam bentuk HSV. Gambar yang digunakan dalam penelitian berupa citra sebanyak 26 kelas huruf alfabet SIBI dan 3 kelas tambahan, dengan masing-masing kelas memiliki 1000 gambar. Kemudian dilakukan cropping dan thresholding dengan menempatkan isyarat tangan yang berbentuk huruf  kedalam kotak yang merupakan area ROI untuk memudahkan pengenalan. Teknologi visi komputer deep learning convolutional neural network (CNN) digunakan untuk feature learning dan mengklasifikasi isyarat tangan pada sebuah obyek. Untuk menguji metode CNN, digunakan berbagai variasi cahaya sebesar 10-200 lux, serta jarak dari tangan ke webcam 50-200 cm. Hasil penelitian dengan metode CNN pada citra isyarat tangan memberikan akurasi sebesar 92%, presisi 91,96%, sensitivitas 91,9%, spesivisitas 91,96% dan f1 score 91,9%. AbstractSign language is usually used by deaf and speech impaired persons. The Sistem Isyarat Bahasa Indonesia (SIBI) is a hand signal language used in Indonesia. The use of hand signals is not always understood by normal humans, such that additional devices are needed to make sign translation easier. The additional device in this study is developed using deep learning and computer vision technology to produce a hand signal translation tool. This study uses 29 sign images for a dataset, consisting of 26 letters of the alphabet and 3 additional signs, namely space, delete, and unclassified. Pre-processing is performed by converting the image into HSV, cropping, and thresholding to make easy recognition. The convolutional neural network (CNN) method is then used as a learning feature and hand signals classifier on an object. The testing phase is performed on various lights ranging from 10-200 lux and the hand distance to the webcam is about 50-200 cm. Experimental results show that the CNN method on the hand signal image could provide an accuracy of 97.2%, precision of 91.96%, sensitivity of 91.9%, specificity of 91.96%, and F1 score of 91.9%, respectively.

Abstract

Predicting immediate future actions taken by an intelligent agent is considered an essential problem inhuman-autonomy teaming (HAT) in many fields, such as industries and transportation, particularly toimprove human comprehension of the agent as their non-human counterpart. Moreover, the results of suchpredictions can shorten the human response time to gain control back from their non-human counterpartwhen it is required. An example case of HAT that can be benefitted from the action predictor is partiallyautomated driving with the autopilot agent as the intelligent agent. Hence, this research aims to develop anapproach to predict the immediate future actions of an intelligent agent with partially automated drivingas the experimental case. The proposed approach relies on a machine learning method called naive Bayesto develop an action classifier, and the Dynamic Bayesian Network (DBN) as the action predictor. Theautonomous driving simulation software called Carla is used for the simulation. The results show that theproposed approach is applicable to predict an intelligent agent’s three-second time-window immediate futureaction.
