Abstract

The Anggrek coal-steam power plant (PLTU) in gorontalo is anpower generation facility that utilizes coal as its primary energy source. In recent years, the energy industry has undergone significant changes, driven by the need to reduce greenhouse gas emissions and increase the utilization of renewable energy souces. Dried white leadtree wood, exposed to sunlight for 18 hours, has a moisture content of 40% and a high calorific value of 4,197 kcal/kg, making it suitable for blending with coal. This power plant applies co-firing, which involves blending 1-5% white leadtree woodwith 1,000 tons of coal daily. This study aims to analyze the electricity generated. Additionally, this study evaluates the needs and procurement of both coal and white leadtree, alongside the sales of electricity in kWh. The methodology involvescollecting monthly data on fuel consumption and cost estimates per kWh generated. The results indicatevthat coal accounts for 95% of the total fuel consumption, while white leadtree contributes only 5%. The estimated cost of purchasing coal for co-firing with white leadstree is IDR 520 per kg, whereas the selling price of electricity is IDR 2.500 per kWh.

Abstract

The development of expeditionary goods separation system technology is currently increasingly leading to automation systems. Including shipping expedition goods. However, currently the process of separating goods during shipping expeditions is still mostly done manually. Therefore, research is needed to create an automatic control system tool that can separate and record expedition goods so that it becomes more effective and efficient. The methodology used is 3 GM66 Barcode Readers to read Barcodes on expedition goods from the top, left and right positions. The reading results are sent to the Arduino Mega R3 and processed to move the servo motor and separate the expedition goods into 3 different sortings according to the destination area and 1 sorting for rejected goods. Reading data from the Barcode is also sent to the WiFi module and processed to be sent to the expedition's goods database. The expedition goods database then displays the data on the IoT control system. As a result, the Barcode reading by the Barcode Reader from the top, left and right positions was read well with an error percentage of 0%. Then separate the expedition goods from the reading results separately according to the destination with an error percentage of 0%. And reading the expedition goods input data through reading the Barcode is stored in the expedition goods database and can be read again based on the Barcode, recipient's name, recipient's address, and No. Recipient's cellphone.

Abstract

In general, traffic light regulations (traffic tights) currently use fixed times where the lights are set to work alternately at fixed times, without paying attention to traffic flow conditions, for example at four intersections in each direction of the road the duration of the light is green, yellow, red at the same time. In this condition, there is a long queue on one side and a very short queue on the other, so setting the time duration equally will result in unnecessary stopping time. This research uses an experimental method which is carried out through the stages of procurement, assembling and carrying out trials. By using a Programmable Logic Controller (PLC) and User Interface (UI) to control and monitor the traffic light system at road intersections with the aim of designing and simulating the traffic light system at intersections manually using GX-Developer software and GT-software Designer3. PLC is used to automatically control the work of traffic lights which regulates the operational time of traffic lights which can respond and follow all commands given by the UI system. So testing the light timing settings at intersections can be set directly in the UI system with the timer in the traffic lights program, the timer from the calculation results, and the timer on the stopwatch having relative time differences. So, the real timer results were obtained on the stopwatch at the green light at intersection 1 for 41,79 seconds, the green light at intersection 2 for 41,79 seconds, the green light at intersection 3 for 25.77 seconds, and the green light at intersection 4 for 21,89 seconds. with yellow lights at all intersections 3 seconds, and red lights at all intersections only 1 second as the delay time between red and green lights at one intersection to another

Abstract

The melting point of medicine is an important factor to determine the purity of medicinal raw materials, thermal behavior is closely related to the melting process of that. This research focuses on developing an intelligent Smart Hotstage-Microscopy prototype to observe thermal behavior in the drug melting process. This prototype heats the drug evenly on a hot plate equipped with a polarizing microscope, thermocouple sensor, microcontroller, and LCD display to view the temperature reading results. The performance of the Smart Hotstage-Microscopy prototype was obtained by testing the thermocouple sensor, heating system, cooling system, and drug validation. In this paper the test results show that the thermocouple sensor test has an R2 value of 0.9983, which shows that the correlation between the actual temperature and the hot part temperature shows a significant correlation, which is 99.83%. Testing the heating system from an average temperature of 28.57°C to the average temperature of 298.59°C took an average time of 11.28 minutes. Meanwhile, testing the cooling system took 5.19 minutes to reduce the temperature from average 298.59°C to 33.379°C. This test proves that the prototype of Smart Hotstage-Microscopy can work well in melting drugs

Abstract

Indonesia possesses significant potential for renewable energy utilization, particularly solar energy, with an average daily solar irradiance of 1,200 W/m². This condition is ideal for the development of Solar Power Plants (PLTS). On the other hand, traffic light systems, although critical for regulating vehicle flows, often rely on fixed time cycles that are inefficient under varying traffic volumes. To address this issue, an adaptive control system based on a Programmable Logic Controller (PLC) is proposed, utilizing a time scheduling method. During the evening rush hour from 16:00 to 17:00, the total traffic light cycle duration is 199 seconds, distributed as follows: the South direction experiences a 147-second wait with 48 seconds of green light, the North waits for 165 seconds with 30 seconds of green light, the East waits for 166 seconds with 29 seconds of green light, and the West waits for 120 seconds with 75 seconds of green light. The yellow light is active for 3 seconds in all directions, and there is a 1-second red light buffer before transitioning between intersections

Abstract

This study explores the performance of Proportional-Integral-Derivative (PID) and Linear Quadratic Regulator (LQR) controllers in regulating BLDC motor speed. The PID controller is tuned using both MATLAB-based auto-tuning and manual parameter selection, while the LQR controller is designed by adjusting the Q and R matrices through iterative optimization. To evaluate their effectiveness, a mathematical model of the BLDC motor is developed in a state-space representation, enabling simulation of its dynamic response. The open-loop system shows a slow response and significant steady-state error, making it unsuitable for precise speed control. The PID tuner improves response time and accuracy, it introduces overshoot. Manual tuning further refines performance by reducing overshoot and enhancing stability. The LQR controller demonstrates the fastest response, minimal overshoot, and the lowest steady-state error, making it the most effective approach for BLDC motor speed regulation

Abstract

Two-wheeled electric vehicles in Indonesia have special specifications with SNI standards on rechargeable battery components. To recharge the battery with a household PLN power source, a charger device is required that meets the input and output specifications. In this study I will design and simulate a battery charger device with an output voltage specification of 72V and a maximum current of 3A. The charger device uses a bridgeless cuk converter topology with an input voltage that adjusts to 220Vrms AC household electricity. By using the specifications on the input and output, the calculation in the design produces a nominal duty cycle value of 18.8% at a frequency of 100kHz, and the component values . The first simulation was conducted with a fixed duty cycle of 18.8% which produced a full-wave sinusoidal output signal where the maximum voltage was -70.5 V and the average voltage was -45 V, the maximum current was -2.93 A and the average current was -1.87 A. The power efficiency of the first simulation result was 96.2%. The second simulation was conducted with a duty cycle control in the form of a comparator from the saw signal and the output voltage of the cuk converter. The second simulation produced a more constant signal with a maximum voltage of -100 V and an average voltage of -73 V, a maximum current of 4 A and an average current of -3.05 A. The power efficiency of the second simulation result was 96.99%.

Abstract

Plastic waste poses a substantial risk, causing blockages in water channels and contributing to flooding incidents. The accumulation of plastic bottles, which can take 450 to 1000 years to decompose, accelerates environmental degradation. The Ministry of Environment and Forestry (KLHK) supports waste utilization industries through the 3R principle (Reuse, Reduce, Recycle), with recycling offering a sustainable way to reuse materials. The advent of Industry 4.0 brings technological advancements, particularly in 3D printing through the FDM method. Addressing this issue requires more efficient waste management, promoting the use of refillable bottles, seeking eco-friendly packaging materials, and recycling PET bottles into 3D printing filaments. This approach provides low-cost value, reducing dependence on virgin materials and cutting waste. Additionally, the development of a mobile app adds integrated value, enabling users to efficiently set up devices for optimized filament production. A clean and sustainable environment necessitates full support from government policies and collaboration among the government, industry, and the community. Filament testing from plastic bottles reveals variations in diameter based on experimental speed. At 4 RPM, the filament measures 1.6 mm, while other speeds result in approximately 1.7 mm. The combination of 2 RPM speed and a temperature of 200°C, and 3 RPM speed with a temperature of 210°C, proves most suitable for high-quality 3D printing of Vase and 3D Benchmark from plastic bottles.

Abstract

The process of heating water to a certain temperature is commonly found in various industries, such as the chemical or food and beverage industries. This water heating is used to improve product quality, but temperature changes often become unstable due to external disturbances. Therefore, to ensure that the water temperature in the tank reaches the desired point with a fast and stable response, a PID controller or fuzzy logic controller is required. In water temperature control systems, the use of fuzzy logic in nonlinear systems is more effective than PID. Therefore, this study aims to compare the Ziegler-Nichols PID control method with the Sugeno fuzzy logic method to determine the appropriate and efficient control method. By examining the system stability and transient response of the water temperature controller as test parameters, it is hoped that the effects of these control methods will be beneficial for industrial implementation, thereby achieving good product quality based on SCADA Wonderware InTouch for monitoring, controlling, and modeling. The comparison between the Ziegler-Nichols PID and Sugeno Fuzzy Logic concludes that the use of Fuzzy Logic controllers has smaller error values and faster and more efficient system responses compared to PID in achieving the desired set temperature of 24 ºC in the experiment.

Abstract

Abstract- Short Term Load Forecasting (STLF) is becoming very important as the use of distributed energy sources, renewable energy, and demand side management increases. Electrical energy is one of the most widely used energy, especially in households. To avoid excessive electricity consumption, we propose a household electricity consumption forecasting system using Convolutional Neural Network (CNN) method. The input of CNN is the power of several household loads measured for one week at 10-minute intervals. This data is used to train the model and predict household electricity consumption for the next week. Forecasting results for a week show a difference in consumption of 3.623 kWh, while with the load management method the difference is 3.439 kWh. With an electricity tariff of Rp1.352/kWh, the estimated electricity cost for the following week is Rp4.892.00, and with load management, the cost drops to about Rp4.649.52 (5% savings).The testing method is done by comparing the forecasting results and actual data for one week. The results show an average difference of only 1.57W with an average error of 0.07%. The CNN method is also compared with the Long Short-Term Memory (LSTM) method. As a result, CNN has better performance with CNN RMSE value of 3.688, CNN management of 3.354, while LSTM RMSE of 12.603, and LSTM management of 13.132. CNN is proven to be more accurate for household short-term electricity load forecasting..
