Abstract

Electrical energy at this time is a very important need to meet the needs of humans, such as lighting, factory machinery, household electricity, and other needs. Electricity flowing from the plant is channeled through transmission lines to be distributed to low- and medium voltage customers. In the process of distributing electrical energy, a device is needed to lower the voltage, namely a transformer. For the purposes of measurement and protection in electrical installations, a current transformer is needed to convert the amount of current on the primary side of large-scale electrical installations into small-scale current quantities more precisely and accurately. Determine the accuracy class of the current transformer to be able to transform primary into secondary. The excitation current will cause deviations from the measurement results. This deviation is commonly known as a transformation error or ratio error. Every single current transformer that PLN will use must meet the criteria of the IEC 60044-1 standard. From the data manager of current transformers in 30 phases at the Kuala Dua substation, it can be concluded that the current transformers with a ratio of 300/5A, 400/5A, 500/5A and 600/5A, core metering accuracy classes of 0.2 S, 0.5, and 1, 5P and 10P protection core accuracy classes. With the maximum error of the metering core ratio of ±0.2%, ±0.5%, and ±1%, and the maximum error of the protection core ratio of ±3% and ±5%.

Abstract

From the results of the RSSI values that occur when researchers observe the walktest method and observe network quality in bandwidth when not using additional devices in the form of access points and after adding bandwidth in the form of access point devices, which are used to test and analyze the quality of an ICONNET telecommunications service system that used. The data retrieved shows that the RSSI results show a good category and index after the addition of an access point device, which helps to strengthen a multilevel home network. In this case several factors affect a network quality. One of them is the number of users at that time, the number of partitions in the terraced house affects the quality of the network, as well as the existence of several room dividers that cannot access the wifi. However, we can handle some of these factors by adding an access point to the multi-storey house. Distance and cable length, that is, cable distance and length greatly affect a network quality, the farther we are from the wifi router, the worse the quality of the network we get, but after adding an access point. In table 4.3 is the result of RSSI recapitulation on 3 different bandwidths. different, the average results for each bandwidth are shown in the form of data before with a bandwidth of 10 Mbps with data before -64 dBm and data after or data after the addition of an access point with an RSSI value of -47 dBm, so there is an increase in the bandwidth of 10 Mbps, namely -17 %,

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. From the research findings, the best turbine voltage regulation occurred at a water discharge of 0.0026 m^3/s, resulting in a voltage regulation of 22.38%.

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

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.
