Abstract

The radial distribution network system is an important part of the electric power system because this distribution system is useful for distributing electricity to loads (customers). the existence of voltage drops and electric power losses in the provision of electrical energy is something that cannot be avoided. There are several ways that can be done to improve voltage, one of which is the installation of Shunt capacitors in the primary distribution network. Voltage drop can occur in the power system due to the loss of voltage stability in the radial distribution network. This study analyzes the value of voltage stability index in 33-bus IEEE and 69-bus IEEE with current injection method power flow analysis. In the 33-bus IEEE system, the existing condition obtained the minimum bus voltage of 0.9131 pu or 11.560 kV occurs at bus-18. By installing 2 units of shunt capacitors in the 33-bus IEEE system, it can minimize active power losses from 202.464 kW to 157.153 kW or by 22.38%.   In the existing 69-bus IEEE system, the minimum bus voltage of 0.9092 pu or 11.511 kV occurs at bus-65. With the installation of 1 unit of shunt capacitor, the voltage at the installation of 3 units of shunt capacitors, the voltage at bus-65 is 0.9514 pu or 12.045 kV, which has increased by 0.534 kV. By installing 3 units of shunt capacitors in the 69-bus IEEE system, it can minimize active power losses from 224.698 kW to 22.994 kW or by 5.21%..

Abstract

Electricity is one of the important energy needs and takes a role in human activities, especially in the Untan Joint Lecture Building, it is very wasteful in terms of electricity usage, we can see from electricity payments in 2022 in May amounting to Rp. 20,111,463, to May 2023 amounting to Rp. 27,504,057. Apart from that lectures at the Tanjungpura University Joint Lecture Building, several inappropriate electrical energy use behaviors were also found. Among them are the use of lighting during the day, air conditioning is turned on when the learning is empty, room facilities are lit when the room is not used and others. As a result, the allocation of high electricity costs in the Untan Joint Lecture Building. To avoid this problem, it is necessary to plan the use of electronic access cards in the Untan Joint Lecture Building. This electronic access card is a tool that functions to cut off or connect electricity to an area or room. So this planning is carried out so that it will provide insight into how to overcome these problems. In this planning, several calculations are carried out, namely total load, energy consumption, energy savings, electrical energy costs, and payback period at the Tanjungpura University Joint Lecture Building. From the results of the calculation of the effect can be seen after the installation of electronic access cards, which can produce large savings, with energy consumption costs after savings in Building A for a month amounting to Rp. 4,203,147,667. And the period needed to cover investment expenditures is the longest for 4 months and the fastest is less than 1 month.

Abstract

The calculation of volume within a three-dimensional structure has the potential to determine its enclosed mass. This research aims to create a system that utilizes data from the HC-SR04 sensor to calculate volume, incorporating the Internet of Things (IoT) for remote monitoring. The study involves the use of HC-SR04 and DHT11 sensors to gather data on filled height and temperature. The measurement approach encompasses mathematical formulas for volume and surface area that correspond to the shape of the compartment. The ESP32 microcontroller serves as the central processing unit. Experimental trials are conducted, manipulating different height levels within the object. The results reveal differences between theoretical estimations and sensor-derived assessments, highlighted by varying outcomes in specific scenarios. The calculated volume of the filled compartment is displayed on OLED-1 and transmitted through the Blynk application. This study significantly contributes to the advancement of a sensor- and IoT-driven monitoring infrastructure, facilitating the observation of filled height and volume in physical objects. Despite certain variations observed in the trials, the outcomes consistently demonstrate minimal error rates.

Abstract

First Person View (FPV) technology is used, where real-time video signals from drones are transmitted to ground stations, and provide a more realistic experience through FPV display through the monitor screen. This research focuses on designing and analyzing the performance of Cloverleaf and Helix antennas as FPV video receivers on Racing Drones with a frequency of 5,8 GHz which are capable of having a greater receiving power range from transmitters than the default antennas on FPV. The simulation results in CST Studio Suite 2019 show that the Cloverleaf antenna with a wire diameter of 1,5 mm and a bend angle of 105 ° has a VSWR value of 1.463, return loss of -14.508 dB and Gain of 10.74 dBi. While the Helix antenna diameter of 0,8 mm has a VSWR value of 1.081, return loss of -28.101 dB and Gain of 15.54 dBi. Testing on the monitor screen, both types of antennas have been successfully realized on the FPV video monitor screen and are able to capture real-time images from the transmitter on Drone Racing. The longest distance reached is 454 m for Cloverleaf antennas, 425 m for Helix antennas, and 374 m for Cloverleaf and Helix antennas combined. Cloverleaf and Helix antennas on monitors are better for near-medium ranges, but the signal decreases and can be lost at longer distances.

Abstract

Indonesia possesses a substantial potential in renewable energy resources, one of which emanates from waste. Palm oil waste biomass stands as a viable energy source, aligned with the escalating adoption of renewable energy in the country, as outlined in the national 2025 primary energy mix targets, which emphasize augmenting biomass utilization as an energy source. The artificial drying process of oil palm empty fruit bunches utilizing an electric drying apparatus at a temperature of 150°C, for durations of 10 and 20 minutes, is geared towards achieving low moisture content and enhanced calorific value of dried empty fruit bunches, rendering them efficient for employment as feedstock in Power Plants. Based on the findings of the 10-minute drying study, a moisture content of 7.88% was attained, in adherence to the Indonesian National Standard (SNI) 01-6235-2000 stipulating 8%. Additionally, the calorific value registered at 4353 kcal/kg. The constructed drying mechanism yielded electricity costs of Rp. 563,433 for a 10-minute drying session each 1 kg sample and Rp. 924,636894 for a 20-minute drying cycle each identical sample weight.

Abstract

The purpose of this study is to analyze the Quality of Service (QoS) parameters on the Iconnet network by measuring throughput, packet loss, delay and jitter parameters when doing online games (mobile legend) and video calls (WhatsApp) with a bandwidth of 10 Mbps and 20 Mbps using wireshark application. This study discusses the causes of reduced QoS parameter values on networks in Singkawang City, data were taken at 3 times, namely morning, afternoon and evening. From all the recapitulation of QoS parameter measurement results, it can be concluded that the value of each QoS parameter can vary for each package which includes bad, good and very good categories even on the same Bandwidth package. The causes of high and low values of QoS parameters are different, Throughput is caused by the number of arrivals of packets measured during the observation process, Packet Loss is caused by the number of queues that exceed capacity, Delay is caused by the low Throughput value and the number of packets sent while the Jitter value is affected by the Delay value. External factors that can reduce the QoS value are weather conditions and the number of devices connected to the network. Network quality during the day and evening is the point when network traffic is very dense or traffic on the network is full (full traffic) where there are many users during these hours. The quality of data transfer speed is assessed with numbers 1 to 5, number 1 is the worst result, while number 5 is the best result. Packet Loss is caused by the number of queues that exceed capacity, Delay is caused by low Throughput values and the number of packets sent while the Jitter value is affected by the Delay value.

Abstract

Matlab is a software that is capable of performing calculations and simulations as well as developing Graphical User Interface (GUI) based application. The development of GUI based application can be used to perform complex calculations, one of which is the calculation of microstrip antenna dimensions. Microstrip antenna is a type of antenna that consists of a thin conductor laid over a dielectric substrate. The purpose of this research and development is to describe the programming language process so as to produce an effective GUI to determine the dimensions of the microstrip antenna to be designed. By providing input values in the form of dielectric constant, dielectric height, frequency, and impedance, the GUI will process this input into output values in the form of patch dimensions, feedline dimensions, and ground plane dimensions. This GUI will be made stand-alone so the users do not need to open the Matlab application to use it. The GUI will present buttons that are easy for users to use where each button has been adjusted to its respective function. The calculation of microstrip antenna dimensions from the GUI will be tested by comparing the output value with output value from the previous journals. In addition, to test the usefulness of each button, the blackbox testing where the result obtained were that all buttons could work according to their respective functions without any problems or errors so that the GUI can be used for determining the dimensions of microstrip antennas. Then, to test the appearance of the GUI, survey of potential users was conducted to determine the level of user satisfaction with resulting GUI.

Abstract

Parek Village is one of the Disadvantaged, Frontier, and Outermost (3T) areas in Landak Regency, West Kalimantan. This village is not reached by the PLN electricity network. To meet electricity needs, in 2011 a 40 kVA capacity PLTMH unit was built in Parek Hamlet and continues to operate until now. To ensure the success of the PLTMH construction in Parek Hamlet, it is necessary to evaluate the existing PLTMH. This evaluation aims to determine the physical condition of the PLTMH and the technical performance of the PLTMH. This study uses primary data, to obtain primary data, namely by survey and direct measurement to the field to obtain data on water discharge, waterfall height, current, and generator voltage and directly see the condition of the components used in this plant. The evaluation results for the dam, Intake, Forebay, Penstock, and Generator house are still in good condition. The overall condition of the main components such as generators and turbines is still working properly. From the results of the measurements taken, the water discharge from the average of each segment is 0.6824 m3/second and the height of the waterfall is 2,8038 m. The results of the calculation of the potential power that can be generated is 12,8384 kW from 32 kW of installed power. While the usage load used by the community is only 5,842 kW. The comparison of the power used by consumers or the local community with the power that can be generated theoretically is 45,5%. This is because the majority of people there have a low economic level. So residents who use electricity from PLTMH only use it for lighting.

Abstract

The grounding system is an important part that must be considered to ensure the safety and reliability of the operation of the electric power system. The grounding system has an influence on the smoothness and safety of the electric power system, especially when there is a disturbance related to the ground. The aim of the grounding system is to limit the voltage between the equipment and the ground to a safe condition for all operations, both normal conditions and when a disturbance occurs. . The earthing resistance value in a building is 5Ω, while for earthing electronic equipment a grounding resistance value of 3Ω is required and for lightning arrester equipment or arresters it is 1.75Ω and some devices even require an earthing resistance value of 1Ω. The design for the construction of Palm Shell Charcoal Media for Earthing Systems was made by considering several problems, such as how to reduce the resistance value to comply with standards (PUIL). One of the efforts made is to design the addition of palm oil shell charcoal with variations in hole diameter and depth of planting the charcoal in the media. The results showed that factors such as the diameter of the charcoal planting medium and the depth of rod planting had a positive influence on the resistance value. The solution that can be applied to achieve optimal earthing resistance values is to increase the diameter of the charcoal media and deepen the rod planting
