Abstract

Technological progress is currently experiencing very rapid development where mobile communication systems are technologies that support seamless communication links. When the user equipment is within range of the eNodeB, factors such as the distance between the user equipment and the eNodeB will affect the signal performance received by the user equipment. In this study, we analyzed the effect of the distance between user equipment and eNodeB on RSRP and SINR values on LTE 1800 MHz technology. The method used is the measurement of the drive test and the calculation of the Link Budget and the Propagation Model. The results and analysis show irregular changes in RSRP and SINR values caused by varying obstacle factors in the propagation environment. According to the calculation results of the Link Budget and the Propagation Model on the research object, it was found that the RSRP and SINR values decreased for every 100 m change in distance from the eNodeB. Based on the comparison, it is obtained that the PCS Extension to Hatta propagation model is close to the drive test measurement results.

Abstract

Microstrip antenna is one of the most important devices in telecommunications systems. One example is the design of a microstrip antenna on a long time evolution (LTE) device. Disadvantages of this microstrip antenna include low gain, poor directionality, low efficiency, resistance losses on the feed line and narrow bandwidth. This research will design a triangular patch array microstrip antenna to increase the gain so that it can meet the desired work specifications with a working frequency of 2.300MHz. The antenna is designed using FR-4 Epoxy substrate material with a size of 120 mm x 60 mm, which has a dielectric constant (?r) of 4.3, a loss tangent of 0.035 and a material thickness of 1.6 mm. Antenna designed using CST studio suite software 2018. The results obtained in the working frequency band 2280.4 MHz – 2370.0 Mhz, middle frequency 2332 MHz, return loss – 47.360dB, bandwidth 24.7MHz, VSWR 1.008, gain 4.39dBi, impedance 49.90 , and unidirectional radiation pattern.

Abstract

Lembah Gumanti Sub-District is one of the sub-districts in Solok Regency where people are on average separated from each other so that they spread out from one another. This is different from people who live in urban areas where they are close to one another. In addition, this area is dominant with hills and trees causing a performance degredation in 2G and 4G network performance. This study aims to find out how the quality of the 2G and 4G network of Telkomsel operators on the causeway in Lembah Gumanti District where data collection is carried out by means of a drive test using Tems pocket. The results showed that for the 2G network on RxLev it still showed poor results while on RxQual it showed good results. While making a call there were also 2 drop calls from 9 call attempts. Meanwhile for the 4G network the RSRP and SINR parameters showed poor results. Therefore, an increase in network performance is needed to increase people's satisfaction in the area.

Abstract

The FTTH network is currently a reliable network concept used in an era where very fast access to information is needed as it is today, but several problems arise in the FTTH network, for example, reduced data transmission speed due to losses in the transmission cable connection or drop core. In this study, activation of the FTTH network will be carried out so that it can function for internet data transmission and observations will also be made of the connection losses on the 10-meter dropcore cable with the number of connections respectively, namely no connection, 1 connection, and 2 connections, where each connection obtains connection losses from 0.00 to 0.02 dB which will affect the total attenuation obtained in the activated FTTH network. Standard attenuation for fiber optic network activation starting from OLT to ONT according to IEEE Std 802.3ah states that the permissible attenuation / loss tolerance is between 20-24 to 29 dB. Splicing losses are caused by errors in the process of joining the fiber optic cable cores. The number of connections in a fiber optic cable can affect the attenuation value in the fiber optic cable. The more connections, the higher the attenuation in the fiber optic cable.

Abstract

This study explores the development and evaluation of a neural network model for predicting diabetes based on clinical data. The model was built using the Keras API with TensorFlow backend. Key steps included data preprocessing, such as feature scaling with `StandardScaler` and splitting the data into training and testing sets. The neural network architecture consisted of an input layer, two hidden layers with ReLU activation functions, and an output layer with a sigmoid activation function, optimized using the Adam optimizer and binary crossentropy loss function. The model was trained over 50 epochs with a batch size of 10, incorporating a validation split of 20% to monitor performance on unseen data during training. The results demonstrated a high accuracy of approximately 97% on the test set, indicating the model's efficacy in predicting diabetes. Further analysis using a confusion matrix revealed a high count of true positives and true negatives, alongside minimal false positives and false negatives, confirming the model's robustness. These findings suggest that neural networks can be effectively employed for diabetes prediction, offering significant potential for integration into clinical decision support systems. However, further validation with larger and more diverse datasets, alongside considerations for data imbalance and model interpretability, is recommended to ensure generalizability and practical application in real-world healthcare settings.

Abstract

Background: Outpatients often complain about hospital services, one of which is waiting time. High complaints have an impact on patient satisfaction. Currently, in several outpatient rooms at the hospital, long queues and long waiting times frequently occur.Objective: This study aims to determine the correlation between waiting time and patient satisfaction at Public Hospital.Method: This study used a non-experimental approach with a cross-sectional design. Samples were 93 patients selected by using random sampling technique at the public hospital in Banjarbaru city. The instruments used were the patient satisfaction questionnaire and waiting time observation. Data were analyzed using the chi-square test.Results: The results showed that 35 (37.6%) patients felt the standard waiting time according to regulations from the ministry of health (60 minutes), while 55 (59.1%) patients were satisfied with the services provided. There was a significant relationship between waiting time and patient satisfaction (p-value = 0.021).Conclusion: It can be concluded that there is a relationship between waiting time and patient satisfaction. Hospitals can implement online registration and manage the arrival of doctors in outpatient care so that waiting times and patient satisfaction can be managed according to minimum service standards
