Two-wheeled self-balancing robot is a popular model in control system experiments which is more widely known as inverted pendulum and cart model. This is a multi-input and multi-output system which is theoretical and has been applied in many systems in daily use. Anyway, most research just focus on balancing this model through try-on experiments or by using simple form of mathematical model. There were still few researches that focus on complete mathematic modeling and designing a mathematical model based controller for such system. This paper analyzed mathematical model of the system. Then, the authors successfully applied a Linear Quadratic Regulator (LQR) controller for this system. This controller was tested with different case of system condition. Controlling results was proved to work well and tested on different case of system condition through simulation on matlab/Simulink program.

This paper presents a robot concept which is the robot can play the instrumental Gamelan music. Gamelan is a percussive instrument. Instrumental Gamelan music keys are consist of 2 octaves in 15 tones. Robot Gamelan music is using proportional-derivative (PD) control system. PD control of the robot is by controlling DC gear motor position to desired Gamelan key position. Robot Gamelan music using ATmega 16 microcontroller as a controller. Feedback of PD control is using magnetic rotary encoder (MRE) sensor. PD control is using the constant. The constant functions of PD control are determining the pulse width modulation (PWM) toward DC gear motor velocity in order to reposition a gamelan key position and pushing down the errors.

This paper proposes a non-destructive technology to control subterranean termites Coptotermes curvignathus Holmgren infestations. In the experiment, the apparatus for termites control used electromagnetic waves at two frequencies: 300 Hz and 300 kHz. Termites were exposure to electromagnetic waves on direct methods with variation of exposure time 15, 30, 45 and 60 min respectively. The use of electromagnetic waves for termites control are very beneficial, they are odorless, noiseless, friendly to environment, and easy to apply. The result showed that electromagnetic waves had an effect to termites. The value of termites mortality was range between 25.45~82.27% and the average value of termites filter paper consumption was between 8.89~39.44%. Meanwhile on control treatment, termites mortality and termites filter paper consumption were respectively 14.05% and 79.88% in average. The highest frequency of electromagnetic waves and the longest irradiation time caused the highest average value of termites mortality. The magnitude field from apparatus was range between 0.069~0.1815 μT, which is safe to utilize around the human body. The best result was achieved on frequency 300 kHz and irradiation time 60 min. These results represent important information about the potential use of electromagnetic waves technology for termites control as an environmentally benign alternative in spite of the insecticides uses.

Plant health is an essential factor to reducethe number of import in a country. In this research, we usepaddy as an example to understand plant health. Ourresearch is motivated by our belief that technology mightaid in reducing chances of failed paddy harvest inIndonesia. To understand the plant health of paddy, wedesigned unmanned aerial vehicle (UAV) integrated pocketcameras to record near infra-red (NIR) light. Apart fromNIR light data, we obtained the normalized differencevegetation index (NDVI) values of paddy to observe theplant health based on the photosystem metabolism thatabsorb red light and blue light and reflects green l ight andNIR light. Based on the test results, the values of NDVI aregiven -0.819672, 0.395018, 0.346667, 0.032680, 0.705628 and0.302817. Based on values of NDVI, we conduct avalidation test with farmers to compare NDVI values wi thactual conditions on the ground. Based on the test, theobtained value of NDVI was in accordance with the actualconditions in the field.

Media pembelajaran merupakan salah satu unsur dalam pembelajaran. Terdapat banyak manfaat yang diperoleh dengan menggunakan media pembelajaran bagi anak didik di Taman Kanak-kanak (TK), salah satunya adalah pembelajaran akan menjadi lebih menarik dan anak didik memiliki antusias yang tinggi dalam mengikuti pembelajaran. Media pembelajaran berbentuk alat permainan edukasi (APE) juga dapat memudahkan guru untuk menyampaikan materi pembelajaran sesuai dengan tema yang diinginkan dan dapat sekaligus mengenalkan anak pada budaya khas daerahnya. Namun, tidak semua TK memiliki media pembelajaran yang dapat meningkatkan antusias anak dalam belajar. Oleh karena itu, dibuatlah APE berbentuk busy book dan media multimedia interaktif berbentuk video animasi yang berisi pengenalan budaya Cina, Dayak, Melayu (CIDAYU) agar pembelajaran dapat berlangsung menyenangkan untuk anak sekaligus dapat mengenalkan budaya yang berasal dari berbagai suku di Kalimantan Barat. Pembuatan busy book yang dilaksanakan di TK mitra berjalan dengan lancar. Para guru di TK mitra sangat antusias dan bersemangat dalam membuat busy book tersebut, karena mereka dapat menambah pengetahuan dan keterampilan baru mengenai media pembelajaran untuk anak di TK. Busy book dan video animasi yang telah dibuat, diperkenalkan kepada anak dalam pembelajaran di kelas dan anak-anak TK terlihat senang dan bersemangat dalam mengikuti pembelajaran dengan menggunakan multimedia interaktif tersebut.

odrat anak adalah bermain. Setiap aktivitas yang dilakukan anak berbentuk berbagai permainan yang mengasyikkan, baik itu dimainkan sendirian maupun bersama dengan orang lain. Dalam konteks permainan, terdapat perbedaan yang cukup signifikan antara anak-anak di tahun 90an dengan anak anak-anak generasi Z yang hidup di masa sekarang, yang dikenal dengan era digital. Perbedaan tersebut terlihat dari jenis permainan yang dimainkan oleh anak-anak. Anak-anak di era digital lebih banyak mengisi waktu luang mereka dengan berbagai aktivitas permainan yang berkaitan dengan digital, seperti permainan yang terdapat di dalam gadget atau smart phone. Berbagai hasil penelitian mengungkapkan dampatk negatif bagi anak dalam penggunaan gadget tersebut, diantaranya adalah content games yang banyak mengandung unsur yang tidak mendidik. Oleh karena itu, salah satu cara yang dapat mengurangi dampak gadget bagi anak adalah dengan menyediakan content permainan yang mengandung unsur edukatif. Adanya multimedia interaktif berbasis sumber daya alam khas Kalimantan Barat dalam pembelajaran di Pendidikan Anak Usia Dini. Melaluimultimedia interaktiftersebut, guru dapat mengenalkan berbagai permainan edukatif kepada anak usia dini, sehingga tidak hanya bermanfaat untuk mengenalkan berbagai kekayaan alam khas daerahnya, namun juga dapat menumbuhkan rasa bangga dan cinta terhadapdaerahnya. Adanya multimedia interaktif tersebut diharapkan dapat meminimalisir dampak negatif terhadap pemakaian gadget oleh anak usia dini

Paper ini membahas tentang evaluasi kualitas layanan internet di Universitas Tanjungpura. Penulis menggunakan dua metode analisis, yaitu Quality of Service (QoS) dan User Acceptance Test (UAT) untuk mengukur kinerja internet di kampus Universitas Tanjungpura. Pada analisis QoS, penulis mengukur beberapa parameter kinerja internet, seperti throughput, delay, packet loss, dan jitter, untuk setiap fakultas di kampus. Hasil analisis menunjukkan bahwa throughput tertinggi berada di Fakultas Teknik (FT) dengan nilai rata-rata 87,90 MB, sementara delay dan packet loss terendah terdapat di Fakultas Ekonomi dan Bisnis (FEB) dengan nilai rata-rata 0,16 ms dan 0,00% secara berturut-turut. Sementara itu, pada analisis UAT, penulis melakukan survei terhadap mahasiswa untuk mengetahui penggunaan internet di kampus dan kepuasan mereka terhadap layanan internet yang disediakan. Hasil survei menunjukkan bahwa mayoritas mahasiswa menganggap internet di kampus memadai dan lancar, serta sering digunakan untuk belajar dan mengakses media sosial.
