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

Way Tahmi River is a crucial freshwater source for the local ecosystem and surrounding communities, providing essential ecosystem services such as habitats for diverse species, clean water, and support for agricultural and fisheries activities. However, anthropogenic pressures, including water pollution from domestic and industrial waste, land use changes, and overexploitation of natural resources, pose significant threats to the river's ecosystem. This study aims to assess the nekton diversity in Way Tahmi River as bioindicators of water quality. The research involved sampling nekton at three different stations, each chosen based on proximity to residential areas, dining establishments, and plantations. Physical and chemical parameters, including temperature, Ph dissolved oxygen (DO), salinity, and water clarity, were measured to evaluate environmental conditions. The results indicated that the identified nekton belonged to Actinopterygii and Malacostraca classes, with varying species composition across the stations. The Shannon-Wiener diversity index showed moderate nekton diversity, while evenness and dominance indices suggested a relatively balanced and stable ecosystem. These findings highlight the importance of nekton as bioindicators and the need for effective management strategies to preserve the aquatic ecosystem of Way Tahmi River.
