Abstract

Islamic Education is a science that is taught to students on the basic of the Qur'an and Hadith, but in reality, there are still students who have difficulty understanding the learning of Islamic Religious Education. This study aims to find out what are the problems of learning Islamic Education at Junior High School 3 Ulakan Tapakis. This study uses a qualitative method with a case study. Data sources were taken from twelve informants through direct interviews using a set of interview protocols. The results of these findings found that there were three learning problems in Islamic Education at Ulakan Tapakis 3 Public Junior High School. The three problems are: i) low pedagogical competence, ii) limited study time, and iii) inadequate learning aids. The results of these findings can be used as initial data for future researchers to examine this issue in the context of different issues.

Abstract

The implementation of Carrier Aggregation makes it possible to expand spectrum use by combining several bandwidth channels that work like a single spectrum. The LTE network is deployed on several bandwidth channels, namely 1.4MHz, 3MHz, 5MHz, 10MHz, 15MHz and 20MHz. Each bandwidth channel that is correlated with the implementation of carrier aggregation will occupy a different and non-adjacent frequency band, namely 900MHz, 1800MHz, 2100MHz and 2300MHz. In this research, we tested the effect of a combination of CAs that occupy non-adjacent frequency bands on uplink and downlink performance. Measuring and analyzing network performance to determine throughput using several supporting software, namely Tems Investigation, Tems Discovery and Gnet Track. There was an increase in the downlink throughput and uplink throughput values due to the implementation of CA compared to not using CA. The maximum Downlink Throughput value in the CA combination is greater than the Uplink Throughput. The maximum Downlink throughput value on CA 20+20Mhz is 9427kbps, while the Uplink value is 1133.28kbps. The maximum downlink throughput value on CA 20+15Mhz is 8272.24kbps, and the maximum uplink throughput value is 745kbps.

Abstract

This study analyzes the effect of implementing Carrier Aggregation (CA) on non-adjacent frequency bands on LTE network performance in the Alai Parak Kopi area, Padang City, by measuring SINR parameters, uplink throughput, and downlink using the drive test method and TEMS application. The results show that CA affects the SINR value, with the highest value at a frequency of 1800 MHz (19.2 dB), followed by a combination of 1800 + 2300 MHz (18.5 dB), and 1800 + 2100 MHz (13.6 dB). CA also affects throughput, with the highest uplink at a combination of 1800 + 2300 MHz, while the highest downlink at 1800 MHz.
