Restructuring The CTC-WINRIP Server

Monthly Progress Report November 2013 Western I ndonesia National Roads I mprovement Project 50 Objectives • The restructuring of network access then the internet do not often die. So that internet access can be used throughout the working day. • Distribution of rations same bandwidth of internet access for each user. Then block the use of downloading software such as IDM who spend a share of internet bandwidth. • Perform automatic recording of internet bandwidth usage, so that administrators can track users who often spends of internet bandwidth. • Improve network and internet security thus minimizing the spread of viruses and intruders from outside. Scope of works • Setting up proxy server, activities to regulate the internet traffic between the user’s computer with the server. So the network activity will be collected and recorded on the server. • Setting up bandwidth manager, Rations same bandwidth of internet access for each user. Then block the use of downloading software such as IDM who spend a share of Internet bandwidth. • Restructuring of the internet network, Rearrangement of the network to access the internet do not often die. So that internet access can be used throughout the working day. Improving the security of the Internet so that minimize the spread of viruses and intruders from outside.. Results of activities 1. Setting up proxy server: • Proxy server facility has been successfully set in CTC-WINRIP using Squid Proxy software. Squid has many types of uses, from speeding up the server, DNS caching, caching of web sites, and search caching computers on the network. Monthly Progress Report November 2013 Western I ndonesia National Roads I mprovement Project 51 • Each user uses a static IP address. So that administrators can track the internet traffic in the office CTC-WINRIP. • Code of DNS server using Norton Internet Security DNS to prevent malware, spyware, spam and viruses. 2. Setting up bandwidth manager: • Internet bandwidth settings using SofPerfect Bandwidth Manager software. This software is useful to determine the Internet bandwidth capacity for each user. • Bandwidth filter SofPerfect Bandwidth Manager can create filters and conditions that are allowed to use the internet bandwidth. • Bandwidth Meter SofPerfect Bandwidth Manager can also display the statistic of the internet bandwidth usage that are running. Monthly Progress Report November 2013 Western I ndonesia National Roads I mprovement Project 52 3. Restructuring of the internet network: On the previous scheme of the internet network at the CTC-WINRIP office, we are connect the internet modem directly to the router and then distributed to each user. So there is no firewall and bandwidth manager to Prevent malware, spyware, spam and viruses. Meanwhile in the new scheme of the internet network, the internet access from the modem to go through the server first. In this server we have set proxy, firewall and bandwidth manager. From server the internet connected to the router and then Monthly Progress Report November 2013 Western I ndonesia National Roads I mprovement Project 53 distributed to each user. It is expected that the internet security is more secure. APPENDIX List of Static IP Address at The Office of CTC-WINRIP NO.

6.8 Quality Assurance

Quality Assurance Engineer has been mobilized now. But the quality assurance activities for the project cannot be reported due to the end of November 2013, there has been no work activity at the beginning. 6.9 Project Risks and Mitigation Measures 6.9.1 Risks Related to Delays Since the detailed engineering design DED is under responsibility of the Design and Supervision Consultant DSC, delay on DSC establishment affected to the procurement of AWP-2 and AWP-3 sub-projects. As discussed previously above, the DED of several subprojects of WP-2 and WP-3 were prepared and completed by respective P2JN. The CTC has then been instructed by DGH to review the DEDs of seven packages completed by the P2JNs package 5, 6, 11, 13, 15, 17 and 19.

6.9.2 Financial Risks

The following factors will be monitored during implementation of the loan project. • Loan Amount • Actual Tender Prices • Price Adjustment • Currency Fluctuation • Current Estimated Situation No risk was detected until preparation of this report since the main program of the loan civil works implementation has not yet been started with contract sign.

6.9.3 Risks Related to Quality

The quality of work is inherently tied to the competence of the Contractors and the diligence of the Supervision Teams. The competence or otherwise of contractors shall be considered at the time of bid evaluation and prior to the award of any Monthly Progress Report November 2013 Western I ndonesia National Roads I mprovement Project 55 contract. The quality of supervision however is influenced by the following factors: • Ensuring that supervision staff levels are fully manned with competent, honest, qualified and experienced personnel. • The provision of properly equipped laboratories with properly trained operators for each package. Package supervision comes under the responsibilities of the immediate supervision teams and the relevant DSC but the Quality Assurance Engineer from CTC.
