Abstract

Di Sekolah Dasar Bundo Kandung yang telah kami survei, ternyata sekolah tersebut tidak memiliki sarana dan prasana yang berbasis IT di ruang membacanya. Bahkan sekolah tersebut juga belum bisa membuat perpustakaan yang sangat bagus dan lengkap. Mereka hanya mempunyai ruang baca dengan ukuran yang sangat kecil, yang hanya menampung 8 orang saja untuk dapat bisa membaca. Lapangan sekolah yang luasnya 900 meter, akan diambil sedikit lahannya untuk pembuatan taman baca berbasis digital. Kehadiran Pojok Literasi Berbasis Digital ini membawa misi khusus yaitu membudayakan minat baca peserta didik yang sejauh ini masih dinilai rendah. Serta memberikan fasilitas yang nyaman dan kondusif bagi siswa untuk meningkatkan literasi informasi. Literasi informasi merupakan kemampuan seseorang dalam mencari, mengoleksi, mengevaluasi atau menginterpresentasikan dan mengkomunikasikan informasi dari berbagai sumber secara efektif dan efisien. Oleh karena itu tim pengabdian akan membuat taman berbasis digital yang dapat menampung lebih banyak lagi peserta didik dalam meningkatkan minat literasinya. Tim pengabdian juga menggunakan media aplikasi Ruang Guru dalam membantu peserta didik dan guru untuk proses belajar dan mengajar di Sekolah Dasar Bundo Kandung.

Abstract

The high price of chicken feed makes it difficult for farmers to develop their livestock business. This is also experienced by Mr. Pardamiyan Siregar, who has 50 chickens of various ages. Chicken is a type of livestock that relatively eats any kind of food, including grains, green vegetables, and household leftovers. It is easy to feed chickens, including the food scraps mentioned above, but it is not always available, and the amount is minimal. Therefore, this service partner must provide feed through ground corn and fine rice bran purchased at animal food stores. The cost that partners must incur is IDR 47,000 per day or IDR 1,410,000 per month. The partner wishes to reduce the feed cost by grinding the round corn purchased from the store. The desire is based on the price difference between round and ground corn. The price of round corn is only IDR 6,000/kg, while ground corn is IDR 8,000/kg so that the partner can save IDR 2,000/kg in feed costs. If the amount of ground corn given to livestock is 3 kg, then partners can save IDR 8,000 daily. The high cost of feed procurement and the promising profit prospects encourage partners to collaborate with the implementation team to find solutions to the problems faced by partners. According to the implementation team, the most appropriate solution to overcome partner problems is the provision of assistance with corn grinding machines. To achieve maximum success in helping partners, the program implementers arranged the following implementation steps: location surveys and interviews to explore the main problems, analyze the situation and conditions of the partner's business, determine solutions, prepare the implementation of machine manufacturing programs, machine grants, training, and program evaluation. The result of this service program is one unit of corn grinding machine with a capacity of 50 kg/hour. The machine uses a 1.5 hp electric motor drive with a grinder rotation of 180 rpm. The size of the corn grains produced ranges from 1 mm to 2 mm. This grain size allows it to be eaten by chickens (poultry) of all ages.

Abstract

Along with the advancement of technology, it brings updates in the digital world, namely the reality of the additional world or Augmented Reality (AR). The application of AR has now been applied in various fields, especially in education. This is because the presence of AR makes the learning process fun. One of the basic learning is reading. However, unfortunately sometimes reading through book media becomes quite boring. For children, now the use of smartphones has become something close and common, so that reading books becomes less interesting because it only displays still images. Therefore, this study was conducted to create an interesting book by combining AR technology. The use of this technology aims to develop children's story books based on Augmented Reality (AR) with 3D animation to increase literacy interest in children aged 6-8 years. This study has succeeded in creating a children's story book entitled The Adventures of Budi and Wati, as well as a mobile application with Android OS and has successfully displayed 3D animation from book illustration images. In this study, data collection was used with literature studies in various sources. The process of creating this 3D animation was carried out in 3 stages of production. Pre-production, Production, and Post-production. In the pre-production stage, the research team carried out story idea and script preparation activities, in the production process, the development process, 3D animation development and AR application development were carried out. In the post-production stage, the product trial process was carried out on several devices. The results showed that the application could be run, but on Android products with OS version 14. Even so, the application product can run well on Android OS 14 and display animations smoothly. AR technology presents characters and stories in interactive visual form, so that children are more enthusiastic about getting involved in reading. The application of this technology not only encourages reading interest, but also stimulates children's creativity and imagination through a more enjoyable and immersive reading experience.
