Abstract

Lengan Robot Berjari telah banyak digunakan pada industri maupun penggunaan dalam bidang pendidikan. Perancangan lengan robot berjari dibagi atas dua bagian, bagian pengendali pada lengan manusia (Transmitter) dan Lengan Robot Berjari (Reciever). Lengan robot berjari ini berbasis mikrokontroler dengan menggunakan ATMega 32A pada pengendali dan ATTiny 2313 pada robot serta dengan media transmisi wireless menggunakan KYL 1020U. Jari-jari robot dikendalikan oleh Flex Sensor Spectra Symbols 4.5 inch Series SEN 08606 dengan memanfaatkan resistivitas dari Flex Sensor tersebut. Flex Sensor adalah sensor lengkung yang fleksibel secara fisik sehingga dapat mengikuti pergerakan jari manusia. Range resistansi sebuah Flex Sensor berkisar 10 KΩ – 40 KΩ. Flex Sensor sebagai pengendali lengan robot berjari memiliki persentase (%) kesalahan (error) sebesar 13% - 37,7%. Setiap perubahan kelengkungan sebesar 1o pada Flex Sensor berbanding lurus dengan kenaikan nilai resistivitas sebesar 113 Ω. Kenaikan nilai resistansi terhadap derajat kelengkungan Flex Sensor akan berbanding terbalik dengan kenaikan nilai arus yang dihasilkan untuk menggerakan jari robot dengan motor mini servo HS-81. Dibutuhkan keseimbangan perancangan antara mekanik dan elektronik untuk menghasilkan kinerja lengan robot berjari yang maksimal

Abstract

SMPIT Harapan Mulia is one of the schools that uses iPad for its teaching and learning activities.  The use of this small, simple and lightweight iPad is certainly one of the solutions to reduce the burden of the books that the students should carry.  All the learning materials can be found easily in the iPad, therefore the students can learn many things anywhere and anytime. In addition, the use of this iPad also will certainly make the students to more focus on the lesson.  The students have an opportunity to be more flexible in terms of self-development.  Besides the benefits provided by the iPad, there are several obstacles that are often faced, including, the use of iPad is monotonous andexcessive use of iPad can reduce student performance compared to those who do not use tablets (according to research from the Organization for Economic Cooperation and Development (OECD) and University of Michigan). Based on observations and interviews with the principal at SMPIT Harapan Mulia, students who use the iPad are more enthusiastic in joining the teaching and learning process. This can be proven by an increase in the average value obtained by the students of SMPIT Mulia Harapan. However, unfortunately the school also often found the students looked bored with their tablets. This is because their iPad is connected directly to MDM (Mobile Device Management), where the MDM manages the content and activities on each student's iPad.  This MDM limits the student's movement, so that they will not get out of line. However, this MDM also makes students feel uncomfortable and not to be free to express themselves.  Therefore, we need a solution to overcome these problems. This dedication is carried out with the aim to maintain the stability of the students' enthusiasm in using the iPad. In practice, this service provides opportunities for students to develop their skills in using the iPad. Students are equipped with the theory of the development of the use of iPad (in this activity, the iPad is used to control the trash robot). Besides that, the service activity also demonstrated and gave a short workshop on the control of garbage robots using the iPad. The results of this dedication were a simple coding and a monitoring module using a Blynk based iPad.

Abstract

The inverter built in this research is used to convert direct current into alternating current with a size of 3000 watts, which has a DC input voltage of 24 volts. This inverter has a large capacity and can generate enough electricity to run different huge electrical devices or several units at once. It's made utilizing energy-efficient technology to cut down on energy waste during conversion. Furthermore, safeguards such voltage surge and overcurrent prevention guarantee the operational safety of the inverter. The inverter was built using the PWM method and variable loads (resistive load, inductive load and capacitive load), with the aim of evaluating the inverter's ability to handle resistive, inductive and capacitive loads and to see how the inverter responds to load changes dynamically. Based on observations and calculations, higher loads are positively correlated with higher inverter power and efficiency. The inverter has a max output of 664.62 watts and 229 Volt is the output voltage attained. This demonstrates that the EGS002 PSW inverter produces AC voltage of high quality with precise and steady characteristics.

Abstract

Teknologi robot yang semakin berkembang pesat telah banyak membantu manusia dalam mempermudah menyelesaikan salah satu kegiatan yaitu memotong rumput. Robot lawn mower dirancang untuk memotong rumput, menghindari rintangan dan bergerak di sepanjang lintasan yang direncanakan. Sehingga kemampuan untuk mengenali lingkungan, perencanaan lintasan dan pengambilan keputusan harus dimiliki. Robot lawn mower adalah jenis robot yang mampu melakukan pergerakan secara otomatis. Sistem navigasi dan penerapan kecerdasan artifisial merupakan hal utama agar robot dapat bergerak secara mandiri. Dalam hal ini, pengendali fuzzy logic diterapkan untuk menemukan titik koordinat yang telah ditanamkan dalam algoritma fuzzy logic yaitu maju, belok kanan, belok kiri dan putar balik. Sensor GPS Neo-6M digunakan untuk membaca titik koordinat dan sensor kompas HMC5883L digunakan untuk membaca arah dalam sistem navigasi robot yang kemudian diproses oleh pengendali dan menghasilkan keluaran berupa putaran roda yang digerakkan oleh motor

Abstract

This research aims to monitor the performance of a 2x100Wp Solar Power Plant (PLTS) using the parameters of current, power, and solar intensity. The monitoring system is designed to record and analyze the electrical output of the solar panel in real-time. The experimental method is used by collecting data directly through current and voltage sensors, as well as light sensors connected to a microcontroller. Data was collected to see the relationship between solar intensity and electrical power generated. The test results show that the intensity of the sun greatly affects the amount of current and power generated by the solar panel. This monitoring system can be a tool for learning and analyzing the performance of small-scale solar power systems in a laboratory environment.
