ANALYSIS AND IMPROVEMENT OF SERVICE QUALITY IN LAMPUNG LIFTING AGENCY WIRELESS COMPUTER NETWORKS IN SUPPORTING GOVERNMENT TASK

2023-08-09T06:21:24+00:00

This study aims to evaluate the quality of internet network in Badan Penghubung Lampung using the TIPHON standard. The assessment is conducted by measuring several network performance parameters, including bandwidth, throughput, delay, and packet loss. The measurements are carried out for four days during office hours using the Axence Nettools 5 and speedtest.net applications. The collected data is then analyzed to obtain the average values for each parameter. The measurement results indicate that the overall quality of the internet network in Badan Penghubung Lampung is classified as very good. The average throughput value is 1,636 Kbps, which exceeds the TIPHON standard. The delay parameter has an average of 40.17 ms, which also meets the TIPHON standard. Meanwhile, the packet loss has an average of 2.75%, which is well below the maximum limit set by the TIPHON standard. However, this study also shows that the throughput value can be influenced by varying weather conditions, with the lowest data transfer speed occurring on the last day of the study. Therefore, for a more comprehensive evaluation of network quality, it is recommended to consider other parameters such as jitter, reliability, and availability.

Preservation of Bengkulu Culture Through SIPEDALU

2024-01-09T01:39:30+00:00

The presence of technology plays an important role in all sectors of life, one of which is the culture and tourism sector. The culture and tourism sector is a sector that has great potential in the development of a region, so special attention needs to be paid to encourage development and progress in this sector, especially culture and tourism in Bengkulu. Bengkulu has a variety of culture and tourism, both natural tourism, cultural tourism and historical tourism which have their own special features and uniqueness that must be developed and preserved. However, until now, information about culture and tourism in Bengkulu Province has not been well published. There are still many tourists and people who do not know about the diversity of culture and tourism in Bengkulu Province. So a new innovation is needed by utilizing web-based technology by building an information system for introducing Bengkulu culture called SIPEDALU. The method used in developing this system is the Waterfall method. The results of this research are an information system for introducing culture and tourism in Bengkulu Province.
