Abstract

This research aims to see the level of feasibility of the existing grounding system in the Dean's Building, Faculty of Engineering, Padang State University. The quality of the grounding can be seen from the measurement results using an Earth Tester. This is intended to see how the grounding system is installed in the dean building. After that, a feasibility study will also be carried out on the value of grounding installed in all engineering faculty dean buildings. A good grounding value should be between 0 and 5 Ω. In this study, the grounding value was measured using the HIOKI FT6031 Earth Tester measuring instrument with a three-point measurement method. This measurement is used to see whether the grounding system installed in the engineering faculty dean building complies with PUIL or not. The results of the research carried out can show that based on ground resistance measurements carried out directly in the Dean's Building, Faculty of Engineering, Padang State University, the measured values ​​do not meet the PUIL 2011 requirements for network systems. Apart from that, there is also a difference in the voltage value between the grounding value on the panel box and the voltage value on the first to fourth floors of the engineering faculty dean's building which is caused by a poor installation system

Abstract

AS/RS is not just a replacement for conventional warehouses, but has become a key element in modern manufacturing systems. However, in its use there are still problems and shortcomings, including the unavailability of a system that can control, supervise, and acquire data from AS/RS and the cycle time when AS/RS performs data storage and retrieval tasks is still below industry standards. To overcome this, a system that is generally called SCADA (Supervisory, Control, and Data Acquisition) is needed. This research uses Arduino Mega 2560 as an AS/RS controller, while the VTSCADA application is used to build a SCADA system on AS/RS. This research uses two approaches. First, calculating the AS/RS cycle time when performing storage and retrieval tasks. Second, comparing the cycle time of the storage system and the retrieval system. The first test results show that the fastest cycle time in the storage system occurs at storage rack point 1 with a time of 3.17 seconds, while the fastest cycle time in the retrieval system occurs at retrieval point 1 with a time of 12.74 seconds. The second test resulted in a difference in cycle time between the storage and retrieval systems, namely 0.42 seconds at storage point 1, 0.38 seconds at storage point 2, 0.51 seconds at storage point 3, 0.31 seconds at storage point 4, and 0.43 seconds at storage point 5. It can be concluded that the application of SCADA to AS/RS is able to increase the cycle time of AS/RS.

Abstract

The sorting or separation process is crucial in the delivery of goods or packages, especially when viewed from the many regions in Indonesia. From the management system of separating goods which is generally still done manually, causing some goods to experience destination errors and delivery delays or commonly called Criss-Cross (CC). Delivery delays are also influenced by human error factors, so special tools are needed to separate goods based on the destination city of the goods, one of which uses a conveyor with a GM65 QR Code Scanner sensor. This sensor works based on commands from Arduino which has been programmed in such a way that it can control all inputs and outputs used in the system. In this system, the goods to be separated are made in the form of 3D mode boxes, where each box is affixed with a different QR code, namely A, B, and C. Each QR code represents the destination city of the goods to be separated, namely city A and city B, but for QR code C indicates data other than city A and city B which will be separated as foreign goods so that in this case it does not match any separation. After testing, the tool can work properly and obtain the results of separating goods in the form of a type of QR code that is read with the destination city of each item that has been separated.

Abstract

The increasing use of air-conditioned rooms in public entertainment venues but allowing visitors to smoke indoors makes some visitors feel uncomfortable. This final project aims to be able to design a carbon monoxide gas control device and carbon monoxide gas monitoring using IoT technology. The methodology for making this tool involves literature study methods in national journals and internet searches regarding projects that have been made before. Then identify problems in the field so that improvements can be made in tool design. In this tool, air content readings use the MQ-135 sensor to detect gas levels. Control uses the Ardiono Uno microcontroller as the data processing center, the ESP 8266 nodeMCU as the data sender to the application. From several experiments it was concluded that the tool operated as expected. It can be seen from the experimental data that the MQ-135 sensor works accurately in detecting the air quality levels in the room. It starts when the sensor detects air levels and then the reading results become input to start activating the relay for on/off the exhaust fan and also perfume, which will be active to neutralize the air in the room. The buzzer will activate when the reading value reaches the programmed gas level. The sensor reading value that is read will then appear on the LCD and also on the Blynk application.
