Abstract

In today's very rapid technological developments, many tools or products are produced that can help humans in every activity they carry out. The application of technology that can facilitate human activities, for example, such as automatic doors. Where everyone who approaches the door, the door will open automatically because the human body temperature is detected. This electronic device that detects body temperature uses the MLX90614 temperature sensor. This tool can work with a distance of about 2 cm. With automatic doors using a temperature sensor, this can be applied to every door of a room with high mobility such as hotel and mall lobby doors.

Abstract

Grounding refers to the connection of an electrical equipment or installation to the ground so that it can protect humans from electric shock , and secure installation components from the danger of abnormal current voltages . This grounding system has low resistance properties, so that the overcurrent in the installation network can be flowed quickly to the ground to minimize damage to equipment in the building and protect the people inside. This study reviews the measurement of grounding around the earth at the efarina university. To find out the condition of the grounding resistance at each grounding, it is necessary to measure each grounding by measuring directly on the grounding installation network using an earth tester using an electrode pin. The calculation of grounding resistance is based on the type of soil, the depth of the electrode rod. The results show that the earth around the campus lobby has met the General Electrical Installation Requirements (PUIL) standard, which is smaller than 5 ohms. However, for earthing around the health faculty, it does not meet the PUIL standard, which is less than 5 ohms.

Abstract

In the development of science and technology in the field of electronics today, there are many benefits that can be felt by the community, one of which is facilitating work in industry and households. Technological developments in the industrial sector such as warehousing have experienced many advances, one of which is the process of moving goods more easily without human intervention but automatically so as to make the logistics process of goods more precise and accurate. The existence of processes that can run automatically can make work processes more efficient, flexible and run continuously. And often see the work of lifting goods that are very human, then a robot function is made to help make human work lighter. Control and automation can be done easily, efficiently and quickly. The control of this item moving robot uses Arduino UNO ATMega 2560 as the robot's control center. The motion system on the robot uses a motor drive, a servo motor to raise and lower the goods hook which functions to lift and lower goods and a DC motor which aims to move the robot from one place to another. The goods moving robot will work continuously until the inventory can be moved completely.

Abstract

Rapid technological advances, especially in technology such as robots, provide a lot of help for humans in tasks that are difficult for humans to do. As in the case of fire disasters that often occur, it has caused many casualties and property losses. When the fire is extinguished, there is a risk that must be borne by the firefighting team when extinguishing the fire inside something. Risks that can occur, such as being hit by objects falling from the roof of a building or fires that are getting worse grow up. In this study, a prototype fire fighting beetle robot will be made where the simulation is carried out by making a fire in an area. Implementation is done by controlling the robot with applications that include the ability to move, detect hotspots and extinguish fires. Prototype of Fire Detection using Infrared Flame Sensor Based on Arduino Atmega 2560 consists of 3 main blocks, namely: Infrared Flame Sensor, Notification, and Fire Extinguisher. This prototype was made so that later it can be realized so that it can help the firefighters in the event of a fire, especially in areas that are difficult to reach by fire engines.

Abstract

In designing the backbone network for the province of West Kalimantan using Dense Wavelength Division Multiplexing (DWDM) and Optical Transport Network (OTN) devices which cover 14 districts and cities consisting of 30 segments, of which 30 segments consist of 14 DWDM OTN sites and 8 Optical Land Amplifier sites ( OLA). From the results of the design and simulation of the backbone network, it was found that the value of the Optical Link Power Budget (OLPB) < 50 dBm where this value is the ideal value in deploying a DWDM OTN backbone network, and the range of the Optical Signal Noise Ratio (OSNR) is between 20 dBm < OSNR < 40 dBm, which is the ideal value for OSNR, and has an Optical Rise Time Budget (ORTB) < 60 ps, and also has a segment margin system of > 7 dB.
