Service Quality Management

Abstract In this paper a model of service quality management based on the process approach has been presented. The first part of the article contains the theoretical framework of service quality and the process approach in management. Next, quality of service process has been presented in reference to a process-based definition in quoted literature. Finally, the outcomes of a customer questionnaire concerning the validity of particular quality attributes has been presented. The collected data in relation to service process quality stages have enabled the development of a of service quality model for process management.

The Impact

This paper deals with the delay, delay variation - jitter, packet loss rate and bandwidth as quality of service parameters, in the form of four types of video quality degradations. The impact of defined levels of degradation on subjective impressions (given as mean opinion scores) is analyzed. ReTRiEVED video dataset with publicly available subjective scores is used in the analysis. Three full-reference measures are used for objective assessment of video quality. The degree of consistency of subjective and objective quality scores is shown through scatter plots and quantitative measures (linear correlation coefficient and correlation of the ranks). Based on the interpolation functions, quality of service parameters are mapped to subjective experience. We show that jitter is a much more destructive effect than other degradation types.

Descriptive Method

The purpose of this study was to analyze research (tangible, reliability, responsiveness, assurance and emphy) on service quality, using the Innovative Internal Service Quality Model (IISQ). The research method used is a quantitative descriptive method using multiple linear regression analysis. The results showed tangible and tangible evidence of the quality of partial services. While the variable reliability, responsiveness, assurance, empathy affect positively on the quality of service is not significant. This means that businesses that involve activities / products actually produce quality services. While other activities are only as a support for improving the quality of service. The responsiveness variable has a dominant influence on service quality, but it is not significant. This shows how the implementation of activities and service providers have a great response to the quality of service, meaning that port service providers are very responsive to the needs of port service users, so satisfied users will get help for those needs.

Sriwijaya State Polytechnic is an educational institution that provides wireless hotspots in every lecture building. With the increasing need for internet, especially on Youtube streaming, it is necessary to have an analysis in each lecture building to find out QoS (Quality of Service) and RMA (Reliability, Maintainability, and Availability) on the Wireless LAN network at Sriwijaya State Polytechnic. This study uses the Action Research method. For QoS measurement using wireshark software and Axence netTools by logging in through the hotspot for each department at the Sriwijaya State Polytechnic, to find out the performance of a network using PRTG (Paessler Router Traffic Grapher) software using the ping IP Address sensor will display the availability monitoring results. The results of the largest measurement of maximum bandwidth are 21,639,256 bit / s in the Business Administration Department, for the highest delay and jitter values are 36 ms and 0.050 ms in the KPA building (Administrative Head Office). The result of the largest packet loss is 0.093% in the Department of Electrical Engineering, for the largest throughput is 0.918 Mbit / s at 1080HD video quality in the Accounting Department. Monitoring RMA aims to determine the performance of an internet network with an Availability result of 99%, this is categorized in good condition. It can be concluded that the QoS measurement results based on the TIPHON version are categorized as very good and the RMA monitoring results have good network performance results as well.Keyword: Streaming Youtube, Parameter QoS, wireshark, RMA ABSTRAKPoliteknik Negeri Sriwijaya merupakan salah satu instansi pendidikan yang menyediakan wireless hotspot di setiap gedung kuliah. Dengan adanya kebutuhan internet yang semakin meningkat khususnya pada streaming Youtube  maka perlu adanya analisis disetiap gedung kuliah untuk mengetahui QoS (Quality of Servie) dan RMA (Reliability, Maintainability, and Availability) pada jaringan Wireless LAN di Politeknik Negeri Sriwijaya . Penelitian ini menggunakan  metode Action Research. Untuk pengukuran QoS menggunakan software wireshark dan Axence netTools dengan cara login melalui hotspot untuk masing-masing jurusan di Politeknik Negeri Sriwijaya sedangkan untuk mengetahui kinerja dari sebuah jaringan menggunakan software PRTG (Paessler Router Traffic Grapher) dengan menggunakan sensor ping IP Address akan menampilkan hasil monitoring availability. Hasil pengukuran terbesar bandwidth maksimal yaitu 21,639,256 bit/s di Jurusan Adminstrasi Bisnis, untuk  nilai delay  dan jitter tertinggi yaitu 36 ms dan 0,050 ms di gedung KPA (Kantor Pusat Administrasi). Hasil packet loss terbesar yaitu 0,093% pada Jurusan Teknik Elektro, untuk troughput  terbesar yaitu 1,681 Mbit/s pada kualitas video 1080HD pada Jurusan Akuntansi. Monitoring RMA bertujuan untuk mengetahui kinerja dari suatu jaringan internet dengan hasil Availability sebesar 99% hal ini dikategorikan dalam kondisi yang baik. Dapat disimpulkan  hasil  pengukuran  QoS berdasarkan versi TIPHON hasilnya dikategorikan sangat bagus dan untuk hasil monitoring RMA memiliki hasil kinerja jaringan  yang baik juga.Kata Kunci: Streaming Youtube, Parameter QoS, wireshark, RMA
