Abstract

One of effective diversity techniques to combat fading on wireless channel is a cooperative communication system in which a source sends information through several relays and then forward it to a destination. A cooperative communication system has shown increased the system performance and reduced the energy consumption. However, it depends on the used relay mechanism that is relay protocols such as quantize and forward (QF) and amplify and forward (AF). In the previous research, energy efficiency of AF relay has investigated for a single-relay cooperative system, but multi-relay is more practical. Therefore, this research focuses on power efficiency in multi-relay cooperative communication system using QF protocol. The research method used is mathematical analysis and computer simulation for outage probability and power efficiency in the multi-relay QF. Simulation result found that multi-relay QF system could provide a high power efficiency, but the efficiency is reduced when the distance ratio increases. Power efficiency can be increased by adding the number of relays in the system. A comparison of power efficiency for QF and AF protocols has simulated, in which power efficiency of multi-relay QF is higher than that of multi-relay AF at distance ratio and power transmit. Thus, multi-relay QF system can provide high performance and power efficiency in the cooperative communication system.

Abstract

At the PT unit, PLN (Persero), there is an issue with the 20 kV electric power distribution system, such as feeder disruption. As a result, many felt sorry for the feeders of PLTA Krueng Isep and PLTU Nagan Raya, whose consumers were without power for extended periods of time. Of course, it can impact how well a business performs, particularly in terms of service and electrical revenue. In order to examine the causes of Sympathetic, study is required. In order to conduct the research, data on disturbances are gathered, tests are run, simulation results are analyzed using the ETAP application, non-directional relays are swapped out for directional relays, protection coordination is reset, and evaluation is done. The findings of this study have the potential to improve performance at PT. PLN (Persero) and decrease or even completely eradicate the incidence of sympathy in the 20 kV distribution network.

Abstract

This community service activity focuses on identifying groundwater potential as an alternative solution to water scarcity in Meunasah Baro Village, Lhoknga District, Aceh Besar, Indonesia. The target beneficiaries were local residents who experience limited access to clean water, particularly during the dry season. The objective of this program was to provide scientific-based information on subsurface conditions to support sustainable water resource planning at the village level. A participatory and applied approach was implemented, involving local community members in site selection and field activities. The technical method used was a 1D resistivity geoelectrical survey with the Schlumberger configuration. Data were collected through field measurements and processed using inversion software to interpret subsurface lithology and groundwater characteristics. The results indicate that the subsurface layers are predominantly composed of silt and clay materials with low to moderate resistivity values. Although water-bearing layers were identified at depths of approximately 43 to 137.5 meters, the resistivity characteristics suggest that the groundwater is brackish. This condition is likely influenced by seawater intrusion due to the proximity of the study area to the coastline. No significant freshwater aquifer was identified.

Abstract

Wild boars pose a significant threat to cassava farmers in the Jantho Baru area, Aceh Besar district, as they can reduce agricultural productivity. The region's location in hilly terrain near a protected forest makes this challenge unavoidable. An initial assessment with farmer groups (partners) identified the need for a monitoring and protection system to manage wild boar infestations in cassava farms. The partner's land, situated 42 km from the Faculty of Engineering, Universitas Syiah Kuala, spans 5 hectares in a hilly area adjacent to the protected forest.To address this issue, an IoT-based technology solution is proposed for monitoring and safeguarding cassava farms. This system includes video cameras that allow farmers to remotely monitor their land via smartphones. Additionally, security measures such as electric fences and speaker outputs, controlled through an Android-based mobile application, are implemented. The system is powered by renewable solar energy through the use of solar panels. The application of this technology is expected to reduce crop losses caused by wild boars, ultimately improving farm productivity.
