Kemajuan teknologi telah berdampak pada seluruh aspek kehidupan manusia, salah satunya adalah pada dunia bisnis begitu pula bersamaan dengan adanya internet. Sebuah website menjadi sarana penyedia informasi, promosi dan komunikasi kepada para pelanggan. Penelitian ini mencoba melakukan analisis terhadap kualitas layanan Website Learning Management System (LMS) Polsri dengan tujuan untuk mengetahui kualitas website LMS Polsri dari sisi pengguna website dalam hal ini mahasiswa Polsri, yang diukur melalui pendekatan WebQual 4.0 dengan tiga dimensi utama yaitu Usability, Information Quality, dan Service Interaction Quality. Hasil penelitian menunjukkan Usability quality dan Information Quality berpengaruh secara signifikan terhadap kualitas website Polsri sedangkan Service Interaction Quality berpengaruh tetapi tidak signifikan terhadap kualitas website Polsri. Kata Kunci : lms, website, webqual 4.0

ABSTRAKPengembangan profesi guru adalah untuk menjaga dan meningkatkan kualitas guru agar semakin professional dalam melaksanakan tugasnya menggunakan media aplikasi Microsoft office power point. Ada beberapa faktor mengapa kegiatan ini diselenggarakan. Ada guru yang tidak terbiasa menggunakan teknologi sebagai media dalam pengajaran di kelas. Sekolah tidak menyediakan fasilitas yang memadai yang memungkinkan guru menciptakan media ajar mereka. Tidak adanya pembimbing dan pendampingan yang memberikan pendidikan singkat tentang bagaimana membuat media animasi untuk pengajaran di sekolah dasar. Dengan adanya pelatihan ini guru-guru SDN 130 Palembang diharapkan mampu menguasai dan memahami fitur dan fungsi yang ada pada Microsoft power point serta mampu membuat animasi untuk pembelajaran dengan menggunakan Microsoft power point.Kata kunci: animasi pembelajaran; pelatihan microsoft power point; presentasi atraktif. ABSTRACTTeacher professional development is to maintain and improve the quality of teachers to be more professional in carrying out their duties using Microsoft Office Power Point application media. There are several factors why this activity is held. There are teachers who are not used to using technology as a medium in classroom teaching. Schools do not provide adequate facilities that allow teachers to create their teaching media. The absence of mentors and mentors who provide short education about how to make animation media for teaching in elementary schools. With this training the SDN 130 Palembang teachers are expected to be able to master and understand the features and functions that exist in Microsoft power point and be able to create animations for learning using Microsoft power point.

Indonesia has a high potential for renewable energy, especially solar power, due to its location in the equator and blessed with an abundance of sunlight. However, the energy potential from the sun is not maximally utilized. One of the efforts to increase the generated electricity and efficiency is by applied the panels in arches setting. This setting is made possible by the availability of the semi-flexible monocrystalline solar panel. This paper investigates the increment of harvested power and efficiency by arranging the solar panel in concave, convex, and plane settings. The data were taken in August 2019, where Palembang experiences the dry season and January 2020 during the rainy season. The highest power produced (20.27 Watt) and efficiency (13.14%) were achieved in a concave setting during the dry season. The convex setting produced more power and efficiency (13.26 Watt and 9.30%) compared to the plane setting (10.24 Watt and 9.71%). These results show that arches setting are more efficient to harvest solar power and give more extensive applications such as to power a dynamics mobile robot applied in agriculture.

In this paper, Robot Two Wheels are developed further to improve performance or intelligence. A Robot Two Wheels is a robot that can move and balance itself on two wheels, maintain its position upright of the earth’s surface on a flat plane. The design includes the Arduino Mega 2560, accelerometer and gyroscope sensors, as well as proportional Integral Derivative (PID) control as the controlling method. Proportional Integral Derivative control is used to determine the magnitude of the DC Motor’s speed and rotary direction as the driver, based on the robotic body’s tilt angle to the surface of the flat plane. The angle of inclination is taken into consideration and the robot moves either in the forward or backward direction to balance itself. When operated, the self-balancing robot continuously rotates its motor in its efforts to balance at upright position. The self-balancing robot movement is not mapped to its range, where the robot will still move randomly to achieve balanced conditions. The concept of this paper is expand the ability of the robot to sense objects around it which is by adding an ultrasonic sensor as an object detector around it, including obstacles or walls around self balancing robots. Detection of obstructions by ultrasonic sensors will maintain the movement of the robot in the safe area to avoid the impact that can occur when the robot is trying to maintain balance.
