Performance Analysis of Dynamic Systems Using Solar Tracker to Improve Solar Panel Efficiency Denny Haryanto Sinaga, Muhammad Aulia Rahman Sembiring, Hasianna Nopina Situmorang, Arianto Nixon Transferando Tambunan, Paulinson Riki Marpaung Department of Electrical Engineering, Universitas Negeri Medan Abstract This paper presents the performance analysis of dynamic systems using a solar tracker to improve solar panel efficiency. The majority of the solar panels are still static, which results in inferior solar energy receiving. to create a perpendicular angle between the solar panels and the direction of the sun^s rays to maximize the absorption of solar energy. By altering the time of the solar module, this research creates a prototype solar tracker that is capable of producing more energy overall than solar modules that are static. For automatic solar module storage, these prototypes used 2 light sensors, an actuator, and a controller. It is expected that by using this technology, solar energy usage can be maximized and a cost-effective electronic control system can be created.

Analysis of Battery Size, Capacity, and Charging in Electric Vehicles with BLDC Motor Drive Arwadi Sinuraya, Denny Haryanto Sinaga, Yoakim Simamora Department of Electrical Engineering, Universitas Negeri Medan Abstract The availability of fossil fuels such as oil, natural gas, and coal is dwindling day by day, while the human need for energy in the form of fuel is increasing. One of the efforts to use alternative energy is the use of battery-based electric vehicles. The battery is one of the most important components of an electric car. The battery is used as an energy source for the entire electrical system and as a place to store electrical energy during the charging process. The battery serves to supply electric current so that the engine can be turned on, lights, and other electrical components. This study aims to design the size of an electric car battery according to its specifications. In addition, an analysis of the calculation of the battery capacity that will be used and the process of recharging it was carried out.

Earthquake data shows that earthquakes have occurred around the study area. From the geological map of the Medan sheet, there are faults which are the source of the earthquake that have not been properly identified but an earthquake has occurred and the cause of the fault is active or inactive. The purpose of this research is to assess the Liquefaction Potential Index regionally. Analysis method with simplified procedure. Location study is in the district of Medan Tuntungan. The results showed that the soil layer consisted of silty loam sand, fine sand, and coarse sand. The depth of the groundwater level is 0.5 to 3.2 meters. The regional liquefaction potential is low to very high for an earthquake of magnitude 5.5 and high to very high for an earthquake of magnitude 7.5 Keywords: liquefaction, earthquake, index, region, SPT Share Link | Plain Format | Corresponding Author (edo barlian)

Improving Concrete Performance on Water Sensitivity by Adding Contaminated Waste Material Ernesto Silitonga, Hamidun Batubara, Parlaungan Hutagaol, Dody Sibuea Universitas Negeri Medan Abstract The high demand on reutilization of the waste material from port dredging work has been an issue for the last 10 years. Previous researches on re-using this waste material on concrete technology is rarely found. The paper covers the impact of waste Port material on improving concrete performance on extreme condition especially on water sensitivity. Various experimental test result identifies that the main characteristics (physical, mineralogical and chemical) of waste material is acceptable to be added in concrete mixture. The amount of waste material added on the concrete mixture is divided on various quantity (5%, 10%, 15% and 20%). Experimental study result shows the amount of 15% waste addition is the best formulation for Unconfined Compressive Strength. Wet-dry test discovers the best amount on improving water sensitivity of concrete is 10% amount of waste material. Nevertheless the mixture of 5% amount of waste material is proved to have the best resistance on acidic attack Keywords: Contaminated Waste material, concrete material, water sensitivity, Unconfined compressive strength, Share Link | Plain Format | Corresponding Author (Ernesto Silitonga)

Teknik Elektro, FT Universitas Negeri Medan Jl. Willem Iskandar Ps V Medan Estate Medan (b)Teknik Elektro, FT Universitas Negeri Medan Jl. Willem Iskandar Ps V Medan Estate Medan (c)Teknik Elektro, FT Universitas Negeri Medan Jl. Willem Iskandar Ps V Medan Estate Medan Abstract Transformer in the electric power system as a means of transforming electrical power from high/medium voltage to low voltage. Three-phase transformers in electric power systems can be connected in a variety of relationships according to the needs of the network and consumers. Implementation in practice in the workshop is difficult to do with the condition of the availability of electricity grid voltage and the available load voltage for various types of loads. The isolation transformer module provides an alternative to the various possibilities of transformer experiments with various variations of transformer relationships and variations in load relationships under voltage conditions according to the network and consumer loads. Experiments of various transformer relationships with balanced and unbalanced loads can be carried out safely for measurement. The results of the empty load measurement show that the input voltage and output voltage show a value that is close to the same.

INTERACTIVE E-BUSINESS LEARNING MEDIA BASED ON ARTIFICIAL INTELLIGENCE M D Mendoza, O R Lubis, O Y Hutajulu Universitas Negeri Medan Abstract Technological developments have an effect on aspects of education that have an impact on learning activities. Technological opportunities in the era of the Industrial Revolution 4.0 represented by virtual presence and presence, have dramatically changed the environment in which we live on a global scale. In this new landscape, people have expanded their ^socio-cognitive capacities through creativity, collective and collaborative social spaces, social interaction and social learning^. In the field of research, it is known that positive social interactions between teachers and students contribute to effective learning. The development of Artificial Intelligence and conversational agents such as Chatbot provides many promising opportunities in the field of education. In education, the use of Chatbots has been tested on a limited basis mainly in higher education institutions with the aim of providing students with support in scheduling, date reminder, information about lessons, etc. Chatbots are considered effective in performing repetitive and predictable tasks and therefore can be an ideal tool in university institutions, especially in the teaching and learning process. One of the lessons that can be used by using Artificial Intelligence-based Chatterbot is e-business. The purpose of this research is to design and create an interactive e-business learning media program with Artificial Intelligence-based Chatbot for students in the Information Technology and Computer Education Study Program, Department of Electrical Engineering Education, Faculty of Engineering, State University of Medan and produce media that makes it easier for students to understand the learning process.
