Abstract

 The Electric Arc Furnace (EAF) transformer is a key component in the steel melting system using a furnace. The transformer functions to convert the electrical voltage from the main electrical network into the electrical voltage needed to form an electric arc in the melting furnace. In this research, the EAF transformer configuration uses a delta-wye configuration with a furnace melting capacity of 10 kg nickel ore. In its working system, this transformer will produce a very high current when the melting system is running. So this process will produce excessive heat on the EAF transformer side. As a result of the significant heat generated in the melting process, this transformer is equipped with a cooling system in the form of transformer oil which is a heat release medium and maintains the correct operating temperature. An appropriate temperature monitoring system will increase the work efficiency of the transformer and prevent excessive damage to the system. The sensor used in the design is the RTD PT 100 sensor which is installed at 7 measurement points. The main controller for data collecting and data processing used is a Siemens PLC. Data that has been processed on the main control device is transmitted to the IoT cloud server using a V-box device. As a human machine interface (HMI) web SCADA is used to read data in real time. From the results of the tests that have been carried out, the highest error presentation value obtained in measurements on the T phase is 0.05%. Meanwhile, when measuring the transformer oil sensor, an error value of 0% was obtained.

Abstract

Work as a nurse requires direct contact with patients, for example when carrying drugs or changing IVs. However, since the COVID-19 pandemic, awareness to reduce direct contact with patients is increasingly needed. Moreover, direct contact with patients with infectious diseases, such as covid-19. For this reason, it is necessary to create a tool / robot that can connect nurses and patients, especially patients with infectious diseases. In this study, a robot design and implementation was made that can assist nurses in delivering drugs to patients, without having to make direct contact with patients. IoT-based designed robots using NodeMCU, ESP8266 and Blynk. NodeMCU ESP8266 is used as a data processor and smartphones are used as remote controls via the internet. Data from the smartphone is processed by NodeMCU then sends a signal to the robot actuator via the L298N driver motor to drive the wheels. Furthermore, the internet-connected IP camera is used for live streaming on smartphones through the V380 Pro application as a directional guide. Then to prevent collisions, the ultrasonic sensor HCSR04 will send data to NodeMCU ESP8266 if there is an obstacle at a distance of 30 cm in front of the robot, so that the robot will move backwards. The experimental results show that the robot can run well where the robot is controlled by a nurse using the Blynk IoT application and V380 Pro on a smartphone via internet media. Then the test was carried out with two methods, namely smartphones using the robot's local Wi-Fi connection and smartphones using cellular networks. The results showed that the response time of the application command on the smartphone to the robot or viewing video results from the IP Camera was affected by the condition of the internet network used.

Abstract

 Currently, the industrial world cannot be separated from plastic waste, one of which is sheet plastic waste, where this type of waste is very difficult to decompose in the soil, so it is necessary to recycle plastic waste by crushing it and then melting it in processing media such as plastic injection machine. Sheet plastic is usually processed through a shredding or crushing process using a plastic cutting machine. Most of the shredding machines in the industrial world still add plastic waste manually, with the shredding machine components still using a single motor which is used to drive the plastic shredding machine. To solve the above problem by adding several components to the plastic waste shredding machine so that it can be operated automatically using an Omron CP1E PLC, adding a blower motor and a traction motor that uses an inverter or PWM (Pulse Width Modulation) which functions to pull the remaining sheets. The plastic is then shredded by a grinder motor and the shredded results are moved by a blower motor to a special waste bin. This research applies research and development methods with a focus on designing a plastic chopping machine that operates automatically with a continuous system, based on a PLC using CX-One software. This research proves that automatic plastic shredding machines can increase efficiency, work safety and reduce production costs.

Abstract

The electrical power generated by a Micro Hydropower Plant (PLTMH) should be fully utilized without any wastage. The PLTMH Suka Sama, equipped with an Electronic Load Controller (ELC), diverts unused electrical power to a ballast load. This action is necessary to maintain system frequency stability in the event of excess power during a drop in demand. The utilization of energy from PLTMH Suka Sama can be improved by using the electrical power diverted to the ballast load to process sugarcane juice into palm sugar using a vacuum evaporator. The potential energy wasted to the ballast load will be calculated based on the comparison data of the power used by the PLTMH and the power wasted during peak and low demand periods over 9 days. The study results show that the power diverted to the ballast load ranges from 2,000 W to over 3,000 W for 4-7 hours per day. This research indicates that the wasted electrical energy can be utilized to produce palm sugar using a vacuum evaporator with a capacity of 2,000 W for 4-5 hours. The wasted energy, if utilized, can produce 2.5 kg to 3.5 kg of palm sugar.

Abstract

In the current digital era, sentiment analysis of Google Play Store application reviews has become a critical key to understanding public opinion on technology products. This study aims to evaluate the effectiveness of ensemble approaches in sentiment analysis compared to individual classification algorithms. The methods employed include ensemble techniques such as Random Forest and Boosting, along with individual algorithms like Naive Bayes and Support Vector Machine (SVM). This research incorporates extensive preprocessing steps, including cleaning, case folding, tokenization, stopword removal, and normalization, to prepare the data before classification. The results demonstrate that ensemble models, particularly Random Forest, achieve superior performance in sentiment classification of app reviews, with accuracy reaching 94.15% for Zoom app reviews and 80.69% for Shopee app reviews. This performance confirms that ensemble approaches are more effective in handling the complexity and variability of review data compared to individually operated algorithms. The study provides valuable insights for application developers to enhance their products based on user feedback. However, there is still room for improvement in terms of optimizing algorithms for highly unbalanced data and developing methods that can handle more complex language nuances. Recommendations for future research include the use of Deep Learning techniques and cross-domain testing to assess the effectiveness of these models in various sentiment analysis settings.
