Abstract

SGSN (Serving GPRS Support Node) is a node which connect GSM network to GPRS network. SGSNfunctions like MSC in GSM system in monitoring MS location or mobility management, paging, datacompression, traffic calculation, charging, security and controlling data accesing prosses. SGSN is connectedbase station by using Gb interface.Data collecting in details of using GPRS service usage is needed to know how far the GPRS servicedevelopes among the customers is one of the systems used those data collecting.The population of this research is P.T Telkomsel cellular operator. The research sample is takenrandomly. Five research samples for each day in five days can be obtained. The sample taken is not based onthe used application. The research variables comprise time duration and file package.The research is conducted by quantitative methode based on the data got from P.T Telkomsel operators,then analyse toward SGSn and effect of time duration toward CDR file formation will be carried out. Theresearch data in the form of SGSN CDR output data and GPRS empirical research dat are the use of G{RS bycustomers seen from the used time duration and data volume.The result of this research will look out how far the effect of the time duration used by customers towardCDR file formation in SGSN is the research finding shows that the time duration used by customersinfluences the amount of file package formed in SGSN so that it can affect the next process. Besides, there aesome factors supporting the data sending delay technically or non technically. Another research findingshows the GPRS service quality of P.T Telkomsel bassed on the research.Based on the research results, it is suggested to do a research on charging GGSN in GPRS, chargingmechanism of each software supporting SGSN. So that the strong point of eacg software we can know.Keyword : SGSN, Duration of time, CDR

Abstract

This study was aimed to examine the effect of gratitude intervention towards people with physical disabilities well-being. The participants were two groups of people with physical disabilities (8 people for experimental group and 5 people for control group). The design of this study was untreated control group design with dependent pre-test and post-test samples. The similar treatment was also given for control group as a waiting list after intervention for experimental group. Well being was assessed using SPANE, PWS, and PTS. The result showed that there are significant differences in wellbeing score between experimental group and control group which are measured by SPANE U test -2,509, p=0,012. PWS U test -2,874, p=0,04. PTS U test -2,590, p=0,010.Keywords: gratitude, gratitude intervention, physical disabilities, well-beingTujuan penelitian ini adalah untuk melihat pengaruh intervensi kebersyukuran terhadap kesejahteraan penyandang disabilitas fisik. Subjek penelitian terdiri dari dua kelompok penyandang disabilitas fisik yaitu kelompok eksperimen berjumlah delapan orang dan kelompok kontrol berjumlah lima orang. Desain penelitian ini menggunakan desain eksperimen dengan pengukuran sebelum dan setelah perlakukan pada subjek. Kelompok kontrol sebagai daftar tunggu. Kesejahteraan diukur menggunakan skala pengalaman positif negatif (SPANE), kesejahteraan psikologis (PWS), dan pikiran positif (PTS). Hasil penelitian menunjukkan ada perbedaan yang signifikan kesejahteraan penyandang disabilitas fisik antara kelompok eksperimen dan kontrol. SPANE nilai Z sebesar -2,509, p=0,012. PWS nilai Z sebesar -2,874, p=0,04. PTS nilai Z sebesar -2,590, p=0,010.Kata kunci: syukur, intervensi kebersyukuran, penyandang disabilitas, kesejahteraan

Abstract

Jaringan komputer kecepatan tinggi dengan waktu tunggu yang besar merupakan bentuk jaringan yang umum di masa depan. Pada jaringan ini algoritma TCP yang umum digunakan mengalami kesulitan di dalam melakukan pengiriman data. Ada beberapa algoritma yang telah digunakan yakni BIC, CUBIC, dan HTCP. Algoritmaalgoritma ini perlu diuji untuk mengetahui kinerjanya jika diterapkan pada jaringan dengan dua topologi yakni parkinglot dan multihome. Hasil pengujian didapatkan algoritma yang paling baik adalah BIC dengan memiliki nilai kinerja yang paling kecil pada pengujian kali ini.

Abstract

Advertisements broadcasting service on radio is required to report data after performing broadcast correctly and should be accountable to the owners of ads on the date, hours of broadcasting and the number of ads that aired under the contract. Therefore, it is necessary to monitor the ads in accordance with the contract between the ads owner and the radio broadcaster. The monitoring can be done by code marking inside the ads as the identity of the owner. The insertion of the Custom DTMF code through the mixing signal was done using the principle of steganography in the time domain. This research was conducted with a variety of ads audio signal that mixed with noise signal and then analyzed regarding on the placement of the custom DTMF code. For detecting on the receiver side, the DTMF Custom signal must have the magnitude level properly. The results showed that the ads audio signal and the inserted custom DTMF codes can be read well by the detector and it wasn’t interfere the ads signal heard by the audience.Layanan siaran iklan di radio membutuhkan adanya lapor-an yang akuntabel baik mengenai hari, jam, dan berapa kali tayangan dalam sehari yang disepakati dalam kontrak antara pemilik iklan dan radio penyiar. Oleh karena itu sangat penting memonitor hal tersebut dari kedua belah pihak. Monitoring tersebut dapat dilakukan dengan mem-berikan tanda di dalam siaran iklannya. Penyisipan kode DTMF Custom melalui pencampuran sinyal ini menggu-nakan prinsip steganografi dalam kawasan waktu. Penelitian ini dilakukan dengan berbagai variasi sinyal audio yang dicampur dengan berbagai derau dan dianalisis penempatan kode DTMF Custom-nya. Untuk pendeteksian disisi penerima, sinyal DTMF Custom nya harus mempunyai level yang tepat. Hasil penelitian menun-jukkan bahwa sinyal iklan dan kode DTMF Custom yang disisipkan dapat dideteksi dengan baik oleh detector namun tidak terdengar oleh para pendengar.
