Abstract

Research has been conducted on lightning strikes with rainfall to determine the relationship between the two. The problem in this study is how the relationship between lightning clouds to the ground with rainfall in Pontianak City. The lightning data used is lightning detector data originating from the BMKG Supadio Station and rainfall on the BMKG website. The method used in this study performed a linear regression test and a correlation test using the Spearman correlation method. The results obtained show a relationship between rainfall and cloud lightning to the ground daily with a Spearman correlation of 0.2237 which means that the relationship between the two variables has weak strength. The strength of the relationship between the number of cloud lightning strikes to the ground with low rain intensity and the 22.37% relationship between rainfall intensity and the number of cloud lightning to the ground. The correlation coefficient obtained is positive. The relationship between the two variables is unidirectional and can be interpreted that high rain intensity will cause the number of lightning strikes to increase. The intensity of rainfall determines less the size of the number of cloud lightning strikes to the ground. The correlation value between the number of cloud lightning strikes to the ground and the intensity of rainfall in Pontianak City in the weak correlation category with a small value (R2) close to zero. The coefficient of determination is 0.088. This means that 8.8% of the variation from lightning strikes can be explained by variable variations in rainfall.

Abstract

The number of blades and helix range in the helical turbine are considered as internal parameters, while the outer radius of the turbine, turbine length, and turbine shaft inclination are regarded as external parameters. Both of these parameters define the geometric characteristics of the helical turbine. The geometric configuration of the Archimedes turbine can be determined using the formulation by Chris Rorres. The designed prototype of the Archimedes turbine has the following specifications: a total of 3 blades (N), an inner diameter (Di) of 11.4 cm, an outer diameter (Do) of 21.28 cm, a turbine length (L) of 80 cm, a screw pitch (Λ) of 25.53 cm, a number of turns (Z) of 3, and a turbine weight of 10.80 kg, with a turbine shaft inclination angle of 30°. From the research findings, the highest turbine performance was achieved at a water discharge of 0.006 m^3/s, resulting in a generated voltage of 41.02 V with a turbine rotation speed of 309.3 rpm.In this research, the experimental method was used, which involved testing the turbine performance by varying the water discharge under both unloaded and loaded conditions (load simulated using a lamp). Throughout the research process, each test data was recorded and analyzed using relevant formulas, and the results were presented in the form of graphs to facilitate drawing conclusions.

Abstract

Internet availability must be sufficient to meet the needs of the era, supported by extensive coverage and robust network stability. Every provider competes in the current internet market, especially in Pontianak City. This research aims to analyze the Quality of Service (QoS) of the 4G LTE networks provided by three widely-used providers in the community. The research results indicate that the Quality of Service of the 4G LTE network in the Waterfront area of Pontianak City falls into the good category. Measurements in the afternoon show good quality, supported by the close proximity between the research location and the Base Transceiver Station (BTS) without interference. However, data transfer speed experiences a decline in some measurements, especially during cloudy weather and busy visitor periods, affecting network jitter parameters. In the evening measurements, despite obtaining fairly good values on some parameters, throughput still receives a poor rating. The decrease in quality in jitter parameters occurs on the first and second nights due to the density of visitors and excessive queuing in the network. The reasons for the poor quality of the cellular network include obstacles from tall buildings, longer transmission distances due to river expanses, and bad weather. Internet user density also affects signal strength. Furthermore, the distance between the BTS and devices plays a crucial role in network propagation, so an efficiently designed 4G network should provide even coverage and consistent quality.

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

This study aims to analyze and design an effective Solar Power Plant (PLTS) in Sambas Regency using the spatial data-based Weighted Overlay method. Sambas Regency, located in the 3T (Disadvantaged, Frontier, Outermost) area and directly bordering Malaysia, faces the challenges of uneven electricity distribution and the growth of energy demand that continues to increase along with population growth. With significant renewable energy potential in West Kalimantan, especially solar energy reaching 20 GW, this research has high relevance in providing sustainable solutions to support the region's energy needs. A GIS-based Weighted Overlay approach is used to determine the optimal location of PLTS by considering various parameters such as NDVI, NDBI, NDMI, LST, Slope, Rainfall, distance to PLN substation, and existing PLTS location points. The results of this mapping and analysis were then integrated into the technical design of the PLTS using PVSyst software. This research successfully overcomes practical obstacles, such as land protected by the Ministry of Environment and Forestry, by providing detailed solutions that can be implemented. With the continuous growth of energy demand in Sambas Regency, the implementation of utility-scale solar power plants is becoming increasingly urgent. Through economic analysis that includes NPV, PI, IRR, and DPP, this investment can be concluded as feasible. With the application of the right methodology, it is hoped that this research will make a real contribution in supporting Indonesia's efforts to achieve carbon-neutral targets and meet energy needs in border areas that are still unelectrified.
