Abstract

The reliable spread of BTS networks with high system capacity poses a challenge for operators in delivering services. An alternative strategy is network sharing, one of which is MOCN (Multi Operator Core Network). MOCN BTS is configured to share RF module and antenna resources by combining frequencies between operators while maintaining each operator's core. On the other hand, BTS not-pair is the conventional operator configuration where RF modules and antennas are installed independently without any connection to other operators. In this final project, a KPI data analysis is conducted for both BTS configuration to assess their reliability. Four BTS samples from two operators (IM3 and 3ID) are taken for this analysis. The analyzed KPI categories include Accessibility KPI, Retainability KPI, and Service Integrity KPI during busy hours. KPI data is obtained from field results and assisted by the technical team from Indosat Ooredoo Hutchison Pontianak. The analysis results indicate that in terms of Service Integrity KPI, BTS MOCN outperforms BTS not-pair, with a difference of 2.590175 Mbps for downlink and 0.286065 Mbps for uplink. Regarding Accessibility KPI and Retainability KPI, BTS managed by 3ID demonstrates better performance compared to those managed by IM3.

Abstract

UAV is an unmanned aerial vehicle controlled remotely by a pilot or automatically by pre-programmed instructions. UAVs are equipped with First Person View (FPV) technology, which facilitates user monitoring. FPV monitoring can be done using with goggles and a monitor screen. The monitor screens available in the market typically use dipole antennas as their default antennas. However, the drawback of the default monitor screen antenna is its limited range, typically only reaching up to 200-300 meters. This research focuses on the design and implementation of biquad antennas for FPV receivers in UAV systems operating at a frequency of 5.8 GHz. The aim is to create antennas with a larger reception range from the transmitter compared to the default FPV monitor screen antenna. Simulation results from CST Studio show that the directional biquad antenna has a VSWR value of 1.508, a return loss of -13.867 dB, and a gain of 3.416 dBi. On the other hand, the omnidirectional biquad antenna with 4 lobes has a VSWR value of 1.7065, a return loss of -11.666 dB, and a gain of 1.973 dBi. Meanwhile, the omnidirectional biquad antenna with 6 lobes has a VSWR value of 1.226, a return loss of -19.863 dB, and a gain of 1.865 dBi. In practical testing on the FPV monitor screen, all three types of antennas were successfully realized and able to capture real-time images from the UAV transmitter. The maximum distances achieved are 634 meters for the directional biquad antenna, 352 meters for the omnidirectional biquad 4 lobes antenna, and 545 meters for the omnidirectional biquad 6 lobes antenna.

Abstract

Pontianak City is an area located in the equatorial area which has an area of 107.82 km2 and consists of 6 districts. Because it is located in the equatorial area, it results in the growth of convective clouds in Pontianak City with the potential for lightning and heavy rain. The purpose of this study was to obtain interpolation modeling of lightning strike density in Pontianak City using geostatistical approaches, namely kriging and IDW methods ((Inverse Distance Weighted). The results of the two methods are compared to obtain feasible parameters to use to determine the density of lightning strikes. Based on the results of the analysis, the kriging method with spherical type is better than the exponential and gaussian methods, while for the IDW method power 3 is better than power 1 and 2. The average lightning strikes per grid in the Pontianak area ranges from 2 to 22 strikes per grid/km2/year. The highest strike on the Pontianak Kota grid with 22 strikes and the lowest on the Southeast Pontianak grid with 2 strikes. Meanwhile, based on the contour map of lightning strike density in the Pontianak City area using kriging and IDW methods, the results for the highest lightning strike range are Pontianak City with a total of 5-20 strikes. As for the lowest lightning strike range, namely Southeast Pontianak with a total of 2-9 strikes.

Abstract

This research investigates the impact of installing Distributed Generation (DG) on power losses in the feeder. The study uses the Newton-Raphson method in a power flow study to determine bus voltage values and power flow for all DG installation scenarios. The research is conducted on Raya 10 and Kijing Feeders, considering two DG installation scenarios: scenario 1 with 1 DG addition and scenario 2 with 2 DG additions. For Raya 10 feeder, DG installations at buses 91 and 91+92 result in reducing power losses by 35.64% and 55.35% for active and reactive power, respectively. In the Kijing feeder, DG installations at buses 35 and 35+48 lead to reductions of power losses by 40.98% and 67.02% for active power in scenarios 1 and 2, respectively. Reactive power also sees reductions of 41.6% and 68.73% in consecutive scenarios. In conclusion, DG installation in medium voltage networks (MVN) has a significantly positive impact on the voltage profile and power losses. More DG units in a feeder improve the voltage quality and reduce power losses. These findings highlight the potential of DG integration in enhancing the efficiency and sustainability of electrical power systems.

Abstract

Electricity is one of the most important aspects of human life. It is required in various sectors. To maintain stability, electricity providers need to accurately forecast the demand for electricity. This research utilizes the Simple Linear Regression method with the assistance of Excel simulation. Based on the calculations, the analysis reveals the estimated power requirement for industrial load at Pelabuhan Kijing, particularly for the next 10 years, with a minimum of 4,053,685 Watts (4.053685 MVA) based on the predicted power consumption for each year, which experiences an average annual increase of 11.28%. The projected load for the year 2033 is estimated to be 5.802129 MVA. This study employs the one-way ANOVA analysis method to examine the data on the increase in the number of connected power loads in the industrial sector at Pelabuhan Kijing. The data collected from 2023 to 2033 indicates that there is no significant difference between the groups based on the ANOVA analysis. This conclusion is drawn from the ANOVA calculations, where the p-value is greater than the predetermined significance level. Thus, the predicted total load increase for the next 10 years suggests that there is no need to add transformer capacity since the existing capacity is sufficient. This research provides a better understanding of the growth trends in connected power loads and transformer capacity requirements at Pelabuhan Kijing within the specified time frame.

Abstract

Installation Wi-Fi is sometimes hindered by obstacles such as wood, concrete, and glass. The presence of these materials may affect the signal strength received by the user. Therefore, research was carried out by enclosing router using PVC, acrylic and glass materials with a thickness of 2mm, 3mm and 5mm and a distance of 2m, 4m, 6m, 8m, 10m, 12m, 10.2m and 11.4m for RSSI measurements and Quality of Service at a distance of 12m and 11.4m in the morning, afternoon and evening. The measurement results show a decrease in RSSI depending on the obstacle and distance. This is because the signal experiences diffraction and reflection which causes the signal strength to weaken and the farther the distance the weaker the signal. Measurements at the moment non-line of sight has quite poor results, especially when the glass barrier with a thickness of 5mm is at a distance of 11.4 with an average RSSI value of 74.6 dBm. QoS parameter results show Throughput When video streaming all have a bad category due to low number of packets. Parameter Packet Loss all of them are in a very good category, showing the least missing packets. Parameter Latency all of them have a very good category though Throughput low, influenced by the number of incoming packets. Parameter Jitter good with 2mm and 3mm barriers, while 5mm in the afternoon is moderate, influenced by Latency.

Abstract

Information is now a basic need for every people, including the people in border areas. Therefore, it is an obligation for the government to provide information media that can be reached by all levels of society, one of which is FM radio broadcast media. This research aims to identify and assess the quality of FM radio broadcasts in the border area of Sambas Regency using several antenna models which in the area is a vulnerable area of signal leakage by neighbouring countries and far from Indonesian broadcast transmitters. The assessment of FM radio broadcast quality is carried out with the determination of SINPO (Signal, Interference, Noise, Propagation, Overall) values and field strength meter measurements. The data obtained were analysed using the Miles and Hubberman interactive data processing technique. From the research conducted, it was found that 10 Malaysian FM radio broadcast channels and 2 broadcast channels from Indonesia where the dominant broadcast was received better by the yagi antenna. There were also broadcasts whose frequencies fell out of compliance with the regulations.

Abstract

This study delves into the impact of MinMax normalization on Oriented FAST and Rotated BRIEF (ORB) data when utilized as input for an Artificial Neural Network (ANN). The primary objective is to compare the accuracy of an ANN model using two distinct types of input data: raw ORB data and MinMax-normalized ORB data. The results underscore the pivotal role played by MinMax normalization in significantly enhancing the performance of the ANN model. Through a series of comprehensive experiments, it becomes evident that MinMax-normalized ORB data consistently outperforms raw ORB data in terms of accuracy. Impressively, the highest accuracy attained through MinMax normalization reaches 76.6%, whereas the utilization of raw ORB data yields a maximum accuracy of merely 51.1%. This noteworthy improvement effectively validates the prowess of MinMax normalization in counteracting the adverse effects stemming from varied scales within raw data. As a result, the ANN benefits from improved pattern recognition capabilities and heightened predictive accuracy.

Abstract

Robotics has seen an explosive increase in usage in the past few decades owing to its abundance of benefits and automation capabilities. The use of robotics is especially prominent in industries where the demand for precise and automatic robots in order to increase production efficiency is high. One of the robots commonly used in these industries is the arm robot model, which is a machine designed specifically to mimic some of the human arm’s capabilities in order to execute certain tasks over and over again, either autonomously or not. This paper will discuss the design of a robotic arm with five degrees of freedom capable of picking up and placing objects with three different colors and sorting the objects based on their size, starting from the largest to the smallest. The inclusion of an additional degree of freedom allows the robot to adjust the rotation of its grip to properly grab rotated objects. With an ESP32-CAM acting as its eyes, the robot is aided by a Python program run remotely on a separate Laptop in order to analyze video stream uploaded by the camera to determine the coordinates, color, size, and rotation of objects placed within the Detection Zone. The implementation of inverse kinematics equations run on an ESP32 microcontroller allows the robot to reach arbitrary coordinates specified by the Python program. Testing revealed that the resulting robot is able to perform the tasks it was designed to, namely recognizing and sorting colored boxes of different colors and sizes, with an accuracy 100% in recognition tasks and an accuracy of 91.5% in sorting tasks.
