Abstract

TThis study aims to optimize the wireless network from blind spots in the AIKOM Ternate environment. These blind spot areas make wireless network users (lecturers, staff, and students) uncomfortable because they have to get close to the nearest network source (access point (AP)) in order to access the internet or intranet network. With this wireless network optimization, the coverage area of ​​the wireless network is adjusted according to the need so that there are no more blind spots. The use of the Wireless Monitoring (Wirelessmon) application to detect the coverage area of ​​each installed AP, which is measured is the receive signal strength indicator (RSSI), including the determination of channel usage from each AP so as not to overlap in channel usage on each AP and the data rate that is experiencing increase and decrease according to the quality of the received signal. The results of this study indicate that after the optimization was carried out by installing the AP at five points. Optimization of the wireless network at the AIKOM Ternate campus was successful with RSSI -61dBm to -44dBm, RSSI was included in the very good category. It is recommended that RSSI measurements use more than one software so that comparisons are carried out, make comparisons of the received RSSI with the resulting throughput on different devices, and network administrators can use the results of this study but the use of devices with specifications that are different from those used in this study is suggested to perform retrieval of data so that the results are maximum.

Abstract

The ability of 4-5 year olds to imitate letters varies; most children cannot yet correctly imitate letters, and they still make mistakes in identifying, naming, pointing to, and writing letter shapes. The purpose of this study is to determine the effect of multimedia letter aids on the ability to write letters A-Z in children aged 4-5 years, and to determine the effect of multimedia letter aids on the ability to pronounce letters A-Z in children aged 4-5 years at Al-Khairat Kalumpang Kindergarten, Ternate City. The research method used is experimental research with a quantitative approach. The research design is a pre-experimental design with a one-group pretest-posttest design combined with a one-shot case study design. The results of this study on letter writing ability data show a calculated t-value of 6.896 > a table t-value of 2.13145. Therefore, based on the decision-making process above, it can be concluded that Ho is rejected and Ha is accepted. For letter pronunciation ability data, the calculated t-value is 8.857 > the table t-value of 2.13145. Therefore, based on the decision-making process above, it can be concluded that Ho is rejected and Ha is accepted. Therefore, it can be concluded that there is a difference in the average between pre-test and post-test letter writing and speaking abilities, meaning that there is an effect of letter multimedia aids on the letter writing and speaking abilities of 4-5 year old children. Based on the results, it can be concluded that there is a significant improvement in the ability to imitate (write and speak) letters in 4-5 year old children after being given treatment in the form of letter multimedia aids. This finding can serve as a reference for educational institutions, parents of young children, and the community, as well as policymakers, in providing multimedia letter displays to stimulate children's letter imitation skills.
