Introducing animals in early childhood can foster children's love for animals. Some media for introducing animals to children are diverse, one of which is a book about animals. Books about animals display various types of animals and information on these animals. But books about animals are less effective in helping parents teach children about animals because they are less interactive. With the development of technology, especially smart phones can help users spread information. Smartphones can load images, videos& text. To help parents introduce animals to children, an animal recognition application on smart phones was developed. The development method used is MDLC, which consists of 6 stages: concept, design, material collection, merging, testing, and distribution. This application is made using the Java programming language on Android with Android Studio. This applications can be used as an interactive learning media to introduce animals to children. This application can display images, videos, animal information and some quizes.

Java Island is one of the regions in Indonesia that has a variety of cultures, one of which is the Javanese script. Javanese script or better known as Hanacaraka or Carakan is a noble cultural heritage of the Indonesian nation, namely the Javanese tribe which has a license and has been officially recognized by UNESCO. Although it has received recognition by UNESCO, it does not necessarily cause Javanese script to be known and in demand by many people. Elementary school students are expected to have the skills to read and write Javanese script to preserve Javanese script. Many elementary school students think that the material for Javanese script is quite difficult, because it is new material, considering that elementary school-aged children are new to the alphabet and do not know other letters, such as Javanese script. The use of Javanese script learning media at SD Negeri Sinomwidodo itself is currently still lacking, namely still using printed media such as textbooks, student activity sheets, Javanese language and writing on the blackboard which looks less attractive to students. From these problems, a solution was obtained to create an educational game of Javanese script using augmented reality technology. The purpose of making this game is to provide learning about Javanese script through educational games for students of SD Negeri Sinomwidodo. This educational game of Javanese script was designed using the game engine unity and developed using the MDLC (Multimedia Development Life Cycle) method. The development of this method is carried out based on six stages, namely concept, design, material collection, assembly, testing and distribution. According to Luther in Binanto, these six stages do not have to be sequential in practice, these stages can exchange positions with each other. Even so, the concept stage should be the first thing to do. This educational game of Javanese script was tested using 3 tests, namely black box, usability and pre-test and post-test. Based on the results of the study, the results of black box testing can run smoothly according to the expected function. In usability testing, the overall average score is 90.60% in terms of usability, convenience and satisfaction in using this game and getting a sig value. (2-tailed) of 0.003 on the paired sample t test method, which means it can have a significant effect, which means this game can have an effect on increasing understanding of Javanese script in SD Negeri Sinomwidodo.

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.
