Abstract

Problems in the Indonesian education system have raised serious concerns over the low quality of education. One of the problems that causes low interest in learning is the lack of interest in the learning media used. Therefore, it is important for schools to create learning conditions that are comfortable, interesting, and provide opportunities for students to participate actively. One solution that can be used is the use of computer-based learning media, such as Augmented Reality (AR), which can increase students' interest in learning. In the context of learning Natural Sciences, understanding the anatomy of the human body is an important aspect. The purpose of this research is to develop an Augmented Reality (AR) application using the Game Development Life Cycle (GDLC) method as a learning medium or introduction to the human skeletal system. This application will be equipped with theoretical materials and 3D-based object views that include the names of related bones. With the development of this application, it is expected to create an interesting and interactive learning experience, increase the effectiveness of the learning process, and avoid boredom for students.

Abstract

Indonesia is an archipelagic country that has a tropical climate. This country is also famous for its wealth in various natural resources, one of which is water. Water is a source of human needs which is important for survival and is used for daily needs such as consumption, bathing, washing and others. As a society, of course you have to pay attention to the quality in the use of water, for this reason the government provides PDAM (Regional Drinking Water Company). In using PDAM facilities, especially in the South Sulawesi area, Mamuju Regency, it is necessary to monitor the amount of usage every month. The meter display is still analog and the amount of tariff or bill that must be paid by the public is not yet listed. The amount of bills that must be paid is the result of recording by PDAM officers who come every month. With this, tools are needed to monitor usage and the amount of bills that will be paid by the Internet of Things (IoT) based community. With this IoT-based control tool, people can see the amount of water used and the tariff they have to pay each month.

Abstract

Air merupakan komponen utama pada peternakan unggas, sebab tubuh unggas tersusun setidaknya 60% - 85% air. Unggas tidak dapat bertahan hidup 2-3 hari tanpa air, sehingga peternak harus rutin mengontrol pemberian air minum tersebut. Pengontrolan secara penuh terhadap pemberian air minum pada unggas, tentunya menyita banyak waktu dan peternak tidak dapat mengerjakan aktivitas lainnya. Agar peternak dapat mengerjakan berbagai aktivitas dan kebutuhan air minum unggasnya terpenuhi, maka perlu dilakukan perancangan inovasi pengontrolan pemberian air minum. Untuk mencapai tujuan perancangan inovasi tersebut, maka alur penelitian yang digunakan adalah pendekatan metode prototipe. Pendekatan metode tersebut dibagian atas tiga bagian penting, persiapan, prototipe dan penyerahan. Tahap persiapan dilakukan untuk mengumpulkan data-data yang diperlukan pada pengembangan sistem. Pada tahap prototipe, peneliti mengenalisa, mendesain kosnep awal sistem, melakukan implementasi desain serta melakukan evaluasi terhadap prototipe yang dikembangkan. Penyerahan dan kepada pengguna dan evaluasi dilakukan untuk mengetahui hasil feedback dari pengguna. Hasil penelitian ini menghasilkan sistem inovasi PADrink dengan keunggulanya pada kemampuanya dalam mendeteksi volume air dan menampilkan informasinya melalui LCD. Setelah melakukan serangkaian pengujian, diperoleh akurasi rata-rata persentase keberhasilan PADrink dalam mengontrol air sebesar 75%, di mana sensor ultrasonik yang digunakan sangat mempengaruhi berhasil atau tidaknya proses pengontrolan air yang diteteskan. Dari delapan kali hasil pengukuran, rata-rata tingkat akurasi seleisih ketinggian air dan pembacaan sensor sebesar 1,8 cm. Sedangkan persentase tingkat eror yang diperoleh dari pembacaan sensor hanya 3% yang menandakan bahwa pengukuran secara manual dan dengan menggunakan sensor tidak memiliki perbedaan yang signifikan.
