The milling process is cutting lengths and thicknesses with a length of 135mm with a first thickness of 13mm, a second thickness of 15mm and a third thickness of 13mm. Drilling process, where this process involves making a hole with a diameter of 10mm. The grinding process is a finishing process that aims to smooth uneven surfaces. And finally, Quality Control is carried out to check whether or not the goods being produced are suitable. Based on the calculation results, the productivity value for making Handle Lifters in 1 day was obtained, where the working hours used were 8 hours, resulting in 17 Handle Lifters.

The largest source of energy currently utilized is still predominantly from fossils. Fossil energy sources are non-renewable so over time they will run out. So it is necessary to utilize renewable energy sources. One renewable energy source that is environmentally friendly and easy to obtain is wind energy. Wind is a collection of air that is experiencing movement due to a difference in pressure on the earth's surface. Wind will move from areas of high pressure to areas of lower pressure. Experimental research on wind energy is a useful energy that can be put to good use. Wind energy is a form of energy that comes from utilizing air flow in the atmosphere to produce mechanical or electrical energy. The main technology used to utilize wind energy is a wind turbine, which converts wind kinetic energy into electrical energy through a generator. Which of course also requires sufficient wind speed so that the wind turbine can rotate and produce mechanical movement in the form of rotational torque which can then be converted into electrical energy. Wind energy has great potential as a clean, sustainable and environmentally friendly resource, as it does not produce greenhouse gas emissions or hazardous waste during its operation. However, wind energy development faces challenges such as fluctuations in wind speed, large land requirements, visual impacts, and potential disruption to local ecosystems. With technological innovation and careful planning, wind energy can be a significant solution to meet global energy needs in a sustainable manner.

University of Sumatera Utara (USU) is the one of the largest and the best universities in Medan which has full of facilities and infrastructure. Nevertheless, currently University of Sumatera Utara does not have a Student Center. The provision of a student center at a university is essential for the development of outstanding students. Furthermore, in the post pandemic COVID-19, humans need a healthier space or place to be live in. Activities that take place indoors require good air quality to prevent viruses from easily entering and thriving inside the room. The application of tropical architecture in the design of the USU Student Center is a consideration in creating a place suitable for post pandemic COVID-19 conditions, and it also serves as a solution for the climate in Indonesia.
 
 

Currently, the development of communication networks has influenced how humans communicate and exchange information. Data communications technology reflects the rapid evolution in the way humans communicate and exchange information. Data communication is the process of exchanging information between two or more devices via a transmission medium, such as cables, radio waves, or other network infrastructure. The goal of data communications is to transfer data from one location to another quickly, efficiently, and accurately. The method used is to look for references from several internet sources such as Google. The OSI model has 7 layers, namely Application Layer, Presentation layer, Session Layer, Transport layer, Network layer, data link layer, physical layer

In this digital era, network speed is very important, because nowadays many people use the internet as a companion in various events. Data communication is one of the means to allow several devices to communicate with each other. To simplify and speed up network usage, the Transmission Control Protocol (TCP) and User Datagram Protocol (UDP) protocols are used as the transport layer during data transfer. In running this simulation using the Cisco Packet Tracer simulation application using bus topology as the topology type.

Green Open Space (GOS) is one of the efforts to deal with increasing GHG emissions because it has the ability to absorb CO2 emissions. Development Area IV Pekanbaru is one of the Development Areas that has the potential to produce carbon dioxide (CO2) emissions, specifically in Bukit Raya Pekanbaru District. This research was conducted to determine the number of motorized vehicles and the value of CO2 emissions produced each day, as well as the value of the capacity of GOS to absorb CO2 emissions from transportation activities in Bukit Raya Pekanbaru District. The method used is recording traffic activities to calculate the amount of CO2 emissions and calculating all public green open spaces with vegetation cover in the form of grasslands and trees with a diameter of ? 20 cm, as well as calculating the percentage of green open space absorption capacity. The research results obtained were that the value of CO2 emissions from transportation in Bukit Raya Pekanbaru District was 67,007,898 tons of CO2/year. Meanwhile, the capacity to absorb CO2 by public green open spaces is only 1,992.32 tons of CO2/year. The results show that public green open space in Bukit Raya Pekanbaru District in terms of absorbing CO2 emissions from transportation is still insufficient with a percentage of only 2.97%.

Universitas Teknologi Yogyakarta (UTY) operates several computer laboratory rooms used daily by students according to their scheduled times. Sometimes, these rooms experience sudden schedule changes, causing conflicts with other room bookings. This research aims to employ an Augmented Reality (AR)-based application for monitoring the dynamic schedule of lab room usage. The method utilizes a marker-based AR application, tested through black box implementation. The application successfully reads markers at distances of 10–90 cm, tilt angles of 10–80 degrees, and light intensities ranging from 40 to 250 lux. Under these conditions, the markers are readable, and the application responds by displaying virtual objects. Users of the lab rooms can utilize this AR application to identify changes in the scheduled usage plans at UTY as they occur.
 
 

Indonesia's natural and cultural riches have attracted the attention of foreign researchers to conduct research in Indonesia.
