Abstract

Laying out a good Wi-fi System requires optimizing the power level which is received from the transmitter to the receiver. The most influential value in determining the performance of the Wi-fi system is the value of the power level, because this value used to determine the coverage area of a transmitter (access point). Using genetic algorithms due to the existence of various references and as suitable algorithm for problems related to optimization. This algorithm can find the best solution from various possible solutions quickly and efficiently compared to other algorithms. Research conducted optimization by comparing the results of optimization with the existing conditions. The purpose of optimization is to arrange access point to produce efficient signal coverage and strength. The research location is on the 6th and 10th floor of the PT. Telkom Witel Rider Building. In the 6th floor there are 13 access points with the coverage area increasing to 59.2% with the signal strength being at -70 dBm to -75 dBm. This research is conducted to find out the ideal position and number of access points. The total access points needed are 13 pieces with a coverage area of 59.2%, and the signal strength value being -70 dBm to -75 dBm.

Abstract

Abrasion is a process of coastline erosion due to continuous increase in sea waves that causes land loss and damages coastal ecosystems. Abrasion on the coast of Dumai City has caused various problems including land loss, difficult access for fishermen to go to sea, and damage to fishing boats due to exposure to abrasion waves. This study was conducted using a qualitative descriptive approach with cases in the coastal area of ​​Dumai City in Mundam Village. Data collection was carried out through in-depth interviews with 5 informants, observation, and documentation to strengthen the data collected. Interactive model data analysis was used in this study. The results of the study showed that the mitigation strategy carried out on the coast of Dumai City used an empowerment approach by raising awareness of coastal communities about the dangers of abrasion which not only impacts land erosion, but can further threaten the livelihoods and lives of fishermen. This activity includes several stages: (1) rehabilitation and planting of mangroves; (2) construction of breakers and wave breakers; (3) strengthening communities through education and training; and (4) monitoring and evaluation.
