2023-05-09T02:08:59+00:00

The electric motor plays an important role in an industry as a driver in a particular system, for example, rotating a pump impeller, fan or blower, moving a compressor, and lifting materials. The electric motor is sometimes called the "work horse" of industry. It is estimated that motors use about 70% of the total electrical energy in the industry. In making industrial motor monitoring and control systems using IoT with the blynk application, it works in showing the parameters of voltage, current, temperature, and RPM. The module consists of an electric motor, a DHT11 sensor, a PZEM004T sensor, an RPM sensor, and an ESP 8266 microcontroller. In the research conducted, the system made is capable of monitoring and controlling many modules. So that the overall monitoring and control system of electric motors in the company can be integrated into a system. In testing the voltage sensor with a measuring instrument there is an error value of 0.04%, while the current sensor has an error of 2.5%, followed by temperature testing there is an error of 1.8%. the RPM sensor parameter has a value of 1.17%. Remote manual control can be controlled using a smartphone with the blynk application so that the operator can immediately turn off the motor remotely if there is a problem or damage to the electric motor.

2023-05-09T02:52:43+00:00

The use of fossil energy sources is increasing along with the increasing need to make reserves of fossil energy sources dwindling. Without the discovery of new reserves, oil in Indonesia will run out in the next nine years, natural gas will run out in 22 years, and coal will run out in 65 years. According to ESDM data, with current technology, the electricity potential from renewable energy reaches 432 GW, or 7-8 times the current total installed generating capacity. Wind energy (wind) is one of the renewable energy potentials, and the most widely available among all energy sources. Therefore, to anticipate the depletion of energy reserves that we have and to take advantage of the existing energy potential, research is being carried out on designing wind turbines so that we can take advantage of the existing energy potential, and not only depend on fossil energy which is depleting, and the main goal is know how to design and get the appropriate size and design of the turbine. From the design results obtained the value of the rotor diameter is 442 mm, the height of the rotor is 884 mm, the blade height is 439 mm, the diameter of the end plates is 486.2 mm, and the diameter of the shaft is 18 mm. As well as from the simulation, the maximum shaft stress value is 30,794 N/m2, the maximum displacement is 0.313 x10-4 mm, the minimum safety factor is 3.028, and the strain value is 0.114 x10-6, where these results can be used as a reference for the manufacture of this wind turbine later.

2023-05-09T02:58:26+00:00

This research is an ex-post facto descriptive study, which aims to determine: a) the results of the safety relay coordination settings (OCR and GFR) and b) the working sequence and operating time of the safety relay when a disturbance occurs in the electrical system of PT. Rekind Daya Mamuju. Electrical system data obtained in the form of Single Line Diagram of PLTU Mamuju 2x25 MW, protection equipment data, and safety relay coordination data which are then processed and analyzed using the ETAP 12.6 program. The results showed that on the OCR inverse time curve the secondary side of the 0.4 kV transformer is set with a pickup current of 0.45 s, the primary side relay of the transformer is 6.3 kV 0.25 s and the relay is connected between unit I and unit II. 0.84 s. The GFR setting value for the definite time curve for the secondary side of the pickup current is 0.4 s, and the relay on the primary side is 0.2 s. The working time interval of the relay to break the disturbance is 0.3 s. Coordination of safety relays for PLTU Mamuju unit I and Unit II has worked well, with no overlapping or miss-coordination curve plot values. The sequence of work and the time of operation of the relay when a disturbance occurs is in the order of the simulation results with the coordinated setting values.

The Tsukamoto Fuzzy Method for Predicting the Availability Status of Goods Inventory Based on Identification with RFID Technology

2023-05-16T02:19:06+00:00

Data collection of goods entering and leaving the warehouse is very important. However, in large companies with hundreds of items being traded, manual recording can take a long time. To solve this problem, an RFID reader is used to record the name of the goods in the warehouse. By using RFID, the recording time can be reduced. Combined with the application of the Tsukamoto fuzzy algorithm, the system can predict the amount of inventory in the coming month to create sufficient inventory or not excess or less and the company can obtain optimal profits due to the process of buying and selling goods. This study aims to create an inventory system that can record goods through scans and can predict inventory in the coming month. The method used in this research is RFID technology and the Fuzzy Tsukamoto method. The results of this study indicate that the application can scan incoming or outgoing goods tags using RFID technology. The system can also predict the amount of inventory in the coming month using the Tsukamoto fuzzy method.

Prototype Monitoring and Controlling of Wastewater Treatment Plant (WWTP) on IoT-Free Output Channels

2023-05-16T02:29:41+00:00

The largest water pollution occurs due to the disposal of waste from the industrial sector, while some of it comes from the household sector. In the labor-intensive industrial sector and the household sector, domestic liquid waste is generated. The high level of liquid waste pollution can be overcome by using a wastewater treatment plant (WWTP). Wastewater parameters according to research that has been done, namely pH, Turbidity, and Ammonia are very important parameters and the main priority for the quality of wastewater discharged into the environment. In this study, a prototype monitoring and controlling WWTP on the output channel was designed by measuring wastewater parameters and an Internet of Things (IoT) based pump output control system. This prototype is programmed with 2 mode options, namely auto mode where the controlling system works based on program commands with target limits, namely pH 6 – 9, Turbidity < 300 NTU, and Ammonia < 20 PPM, if the wastewater measurement value is on target, the system activates the outgoing pump. for direct disposal to the environment. Meanwhile, if it does not meet the target, the system activates the treatment pump to return the wastewater back to the WWTP. Then the manual mode, which is the controlling system, works by operating the operator directly to activate the outgoing or treatment pump on a smartphone using the Blynk application. In Auto and Manual mode, wastewater parameters can be monitored on a smartphone using the Blynk application. All sensors used have been calibrated with 2 calibrator solutions. The calibration results show an error value of 0.115 for the pH sensor, an error value of 0.075 for the Turbidity sensor, and an error value of 0.115 for the Ammonia sensor.

E-Transaction Point Of Sales (Pos) With Fuzzy Tsukamoto Algorithm At Pt. Samihasa Kita

2023-05-16T02:32:15+00:00

PT. Samihasa Kita is a glass product distributor company that was founded in 1989, which is located in the city of Semarang, Central Java, with sales area coverage in Central Java, D.I Yogyakarta, Jakarta, and Kalimantan. So far, PT Samihasa Kita has an erratic amount of demand for goods, as a result, sometimes the number of goods produced for sale with the goods purchased by consumers is not balanced. This resulted in PT Samihasa Kita not getting the maximum profit. Based on this problem, Fuzzy Tsukamoto logic was chosen to determine the optimal daily production amount. By using fuzzy logic can be determined the relative size of the production of goods. The Fuzzy Tsukamoto method can also be used to forecast sales in the coming month based on the amount of inventory. Thus the amount of production and demand for goods PT. Samihasa Kita is predictable and balances transactions. This research aims to be able to predict demand and procurement of goods that will have an impact on optimizing revenue at PT. Samihasa Kita.
