4G LTE (Long Term Evolution) Network Optimization Using Physical Tuning Methods for the Kubu Gulai Bancah Area.
type: item
description: This study aims to optimize the 4G LTE network in the Kubu Gulai Bancah area, West Sumatra, which is a suburban area with weak signal and unstable internet speed challenges. The main problem identified is that the network quality is not yet optimal based on Telkomsel's Key Performance Indicator (KPI) parameters, as well as the need for an appropriate optimization method to improve this quality. The research methodology involves a drive test using the G-NetTrack Pro application on a Redmi Note 13 Pro 5G smartphone to collect RSRP, SINR, and Throughput data. The collected data is then processed using MapInfo for visualization and analysis, and simulated with Atoll software for optimization planning. Initial drive test results showed that while RSRP was mostly in the “very good” category (55%) and Throughput was predominantly ‘good’ (84%), SINR was still dominated by the “poor” category (56%). Optimization was performed using physical tuning, specifically adjusting the tilt and re-azimuth of the antenna at Site Campago Ipuh 2, Sector 1, with an azimuth change from 0° to 65°. After optimization, the bad spot area for RSRP decreased from 13.2% to 10.89%, and for SINR from 14.1% to 13.21%. The good category for Throughput also increased from 30.5% to 32%. This optimization successfully improved signal coverage quality and network performance significantly.

title: Design And Analysis of Optical Line Terminal (OLT) And Optical Distribution Cabinet (ODC) Devices In The Fiber To The Home (FTTH) Network Trainer Module In The G316 Laboratory, Building G, State Polytechnic Of Padang
description: This study aims to design and analyze the performance of Optical Line Terminal (OLT) and Optical Distribution Cabinet (ODC) devices in the Fiber to the Home (FTTH) network trainer module at the SKSO G316 Laboratory, Padang State Polytechnic. The research methods included design simulation using Optisystem software, physical implementation of the trainer module, and attenuation measurement using an Optical Power Meter (OPM). The results show that attenuation under normal core conditions (orange) is stable in the range of 14.94–16.23 dB, while core bending (green) and core damage (blue) conditions cause a significant increase in attenuation to 16.28 dB and 16.01 dB at a wavelength of 1310 nm. The length of the dropcore cable (10 m, 15 m, 20 m) showed an effect on the increase in attenuation with an additional attenuation increase of 0.9 dB per 5 meters. The simulation results and actual measurements are consistent with the link power budget calculations and meet the technical specifications with total attenuation below the maximum limit of -28 dB. This trainer module is useful as a learning medium for analyzing FTTH network performance and the impact of physical disturbances on optical fiber transmission.

Design of a Real-Time Voltage Monitoring System for PLN and Generator Using Telegram and ESP32
type: item
description: In modern society, electricity is essential for both daily life and industrial operations. Frequent power outages in Indonesia frequently cause disruptions to household, office, and industrial operations, especially during periods of high demand. As a solution, generator sets (gensets) are commonly used as backup power sources. However, manual checks are still used in many installations for monitoring and switching between PLN (State Electricity Company) and genset sources, which can raise operational risks and delay response times. While switching is addressed by existing systems like Automatic Transfer Switches (ATS), they typically do not include real-time notifications or integrated remote monitoring. Using an ESP32 microcontroller and PZEM-004T voltage sensors, along with the Telegram Bot API, this study suggests designing and implementing a real-time voltage monitoring system. The system finds the active source, measures voltage from PLN and genset sources, and instantly alerts users via Telegram. In comparison to a calibrated multimeter, performance testing reveals an average notification delay of less than 5 seconds and a voltage reading error margin of less than ±2%. By offering an affordable, scalable, and interactive monitoring solution, the developed system fills in the gaps in earlier research. It improves responsiveness and dependability in settings that need constant electrical monitoring by giving users access to real-time updates on voltage levels and power source status.

Network Design and Activation Fiber to The Building (FTTB) and Measurement of The Damage Value of Optical Distribution Frame (ODF) To Optical Distribution Cabinet (ODC)
type: item
description: The need for high-speed internet continues to increase with technological developments. Fiber to the Building (FTTB) is a solution for providing fast internet access to commercial and residential buildings. However, the main challenge in maintaining network quality is attenuation in fiber optic cables, especially at connections. This research aims to analyze the effect of pigtail cable length and connection quality on the total attenuation from the Optical Distribution Frame (ODF) to the Optical Distribution Cabinet (ODC) in the FTTB network, both before and after activation. The research method uses pigtail cables of varying lengths, from 30 cm to 150 cm. Some connections are carried out according to Standard Operating Procedures (SOP), while others are not, to measure the effect of connection quality on attenuation. Measurements were carried out using an Optical Power Meter (OPM) and Passive Optical Network (PON) technology with an SFP of 8 dB. The research results show that connections that comply with the SOP produce lower attenuation, namely 7.16 dB on a 150 cm cable, 7.09 dB on a 120 cm cable, and 6.99 dB on a 100 cm cable. On the other hand, connections that do not comply with the SOP produce higher attenuation, namely 8.15 dB on an 80 cm cable, 8.08 dB on a 50 cm cable, and 8.02 dB on a 30 cm cable. This research contributes to the optimization of FTTB network installations.

Design of Fiber Optic-Based Trainer Module with Bus Topology Method Using Optical Distribution Point
type: item
description: The fiber optic based trainer module designed for Politeknik Negeri Padang, especially in the Telecommunication Engineering Study Program for the Fiber Optic Communication System course, aims to improve students' understanding of optical fiber. This module provides an opportunity for students to practice optical fiber splicing and identify problems in the bus topology directly. The module design includes a block diagram showing the components and tools used, including an HLS (Heights Light Source) to provide the input signal and an OPM (Optical Power Meter) to measure the optical power at the Optical Distribution Point (ODP). Measurements are made to ensure attenuation in accordance with the predetermined link budget value: ODP1 with passive splitter 1:2 (8.0007 dB), ODP2 with passive splitter 1:4 (18.4517 dB), ODP3 with passive splitter 1:4 (28.9035 dB), and ODP4 with passive splitter 1:4 (38.555 dB). The measurement results show that correctly performed splicing results in attenuation below the link budget value. However, in ODP1, the disconnection of the pigtail caused the attenuation to exceed the link budget value by -50.00 dBm. The module proved to be effective in teaching but requires more attention to pigtail maintenance and the addition of a troubleshooting guide to improve its reliability.

Analysis of Dirty Adapters and Dirty Connectors on Fiber Optic Transmission
type: item
description: The author conducts research on dirty adapters and dirty connectors in fiber optic transmission to determine the value or attenuation that will be produced due to the influence of dirty adapters and dirty connectors. This study was conducted to evaluate the attenuation value due to dirty adapters and dirty connectors in fiber optic transmission before and after the use of Passive Splitter 1: 16. The method used includes the initial step of calibration between the Optical Power Meter (OPM) and Handheld Light Source (HLS). The HLS was connected to the first Optical Distribution Point (ODP) with a patch cord cable to provide attenuation, and data was taken at the second ODP using the OPM. The power data received on the unproblematic core (gray) without the 1:16 Passive Splitter was 0.65 dB, while with the 1:16 Passive Splitter the attenuation increased to 13.71 dB. The red dirty adapter causes 5.99 dB of attenuation without the Passive Splitter 1:16 and 19.21 dB with the Passive Splitter 1:16. The brown dirty connector exhibits an attenuation of 4.68 dB without the Passive Splitter 1:16 and 19.08 dB with the Passive Splitter 1:16. These findings suggest that the physical condition and cleanliness of the components significantly impact the attenuation in the fiber optic network.

Assessment of the groundwater quality in Sebha, Libya, for drinking purposes
type: item
description: The study examined water samples from wells in Sebha, analyzing their physicochemical properties such as pH, EC, TDS, Cl-, Na+, K+, Ca2+, Mg2+, NO3-, HCO3-, TH, and SO42-. The results revealed significant increases in EC, TDS, Cl-, Na+, K+, Ca2+, NO3-, TH, and SO42- concentrations. However, pH, Mg2+, and HCO3- remained within permissible limits set by Libyan and World Health Organization standards. The study also noted more pronounced changes in the physicochemical properties of water from wells in Abd-Alkafi1, Abd-Alkafi2, and Aljadeed on the western side of Sebha compared to those in Alnaserayah and Hajara on the eastern side. Correlation analysis showed strong positive correlations between EC-TDS, TH-Ca2+, and K+-Na+ at a significant level of p<0.01, and positive correlations at a significant level of p<0.05 between EC- Cl-, Cl--HCO3-, Cl-- K+, Cl--Na+, SO42- - Na+, HCO3-- NO3-, and HCO3-- K+. The strong correlation between Na+ and Cl- indicated high concentrations of these ions in most samples, likely formed from chloride salts through chemical weathering. Similarly, a positive correlation between SO4-- and Na+ suggested that some of these ions resulted from weathering of magnesium and sodium minerals. The Water Quality Index (WQI) categorized water from Alnaserayah and Hajara as suitable for drinking, while water from Abd-Alkafi2, Abd-Alkafi1, and Aljadeed was deemed poor quality. Comparing the current results to a 2001 study revealed a significant increase in the measured elements' concentrations and deterioration in water quality.

description: The quality of irrigation water available to irrigators significantly impacts crops and yields. Therefore, there is a need to understand irrigation water quality better. The present study mainly focuses on assessing the suitability of water in five bore wells of the Aldabwat agriculture project in Alshatti, Libya. The well water samples were evaluated for agricultural uses according to the universal standard classification. Separate bore wells have been analyzed for various water quality indices, including exchangeable sodium percent (SSP or %Na), residual sodium carbonate (RSC or RA), Kelly’s ratio, permeability index, potential salinity (PS), magnesium hazard, total dissolved solids, and total hardness. Most of the wells fall under the moderate water category for irrigation purposes. The analysed water was specified as having a low restriction according to the water quality index (IWQ index).
