Why is it important? for competitive reasons, most companies already refresh their computer hardware every three to four years 2. virtualization technology enables you to reduce equipment and system management costs for your data center 3. all large companies are moving to such implementation improvements 4. Corporate social responsibility 1.

Consider this! Electricity usage is calculated using volts (V), ampere (A), and watts (W) by following formula:
W=VxA Electricity bill is paid using kiloWatt hour (kWh) unit One floor office has 100 lamps each of 10 Watt on for 1 hour consume electricity of 1 kWh Basic fare of electricity in Indonesia on average roughly Rp 600-Rp 900 /kWh depends on the classification How much you pay if the lamps on for 24 hour in 10 floor building? 8

Data centers almost always represent the starting point for green IT initiatives for companies Data centers—the facilities that primarily contain electronic equipment used for data processing, data storage, and communications networking—have become common and essential to the functioning of business, communications, academic, and governmental systems Example: Google is said to have more than 450.000 server in the whole server 10

Demand for data centers Increase in electronic transactions in financial services, such as online banking and electronic trading Growth of Internet communication and entertainment use Increase in online shopping and related transactions Shift to electronic medical records for healthcare Growth in global commerce and services Adoption of satellite navigation and electronic shipment tracking in transportation 11
Significance implications Increased energy costs for business and government Increased emissions, including greenhouse gases, from electricity generation Increased strain on the existing power grid to meet the increased electricity demand Increased capital costs for expansion of data center capacity and construction of new data centers

The strategies and goals of GDC 1. Minimizing the footprints of the buildings 2. Using low-emission building materials, carpets, and paints 3. Creating sustainable landscaping 4. Initiating waste recycling 5. Installing catalytic converters on backup generators 6. Using alternative energy technologies such as photovoltaics(PVs) and fuel cells 7. Increasing the efficiency of heat pumps, variable speed fans, and freecooling technology 15

Enterprises that have started the green journey, have found that reducing total energy requirements can be accomplished through some fairly straightforward improvements that don’t take years to implement or to bring return According to a survey of 124 IT operations, some 85 percent of respondents said environmental factors are important in planning IT operations; But only onefourth of survey respondents have actually written green criteria into their company’s purchasing processes 17
1# Communicate Green IT Plans and Appoint an Energy Czar Measuring the current state of affairs, energy wise, is one of the first steps to take communicate your proposed energy-efficiency initiatives right away Inform all employees about the plans and goals to save energy via green IT set up an organization to drive the effort by making one person responsible Collaboration Is Key for Green IT 18

2# Consolidate and Virtualize Consolidating IT operations, and using virtualization to reduce server footprint and energy use Largest technology organizations in the world— including Advanced Micro Devices®, HewlettPackard®, Intel®, IBM, and Sun Microsystems®—have recently (2008) completed major data center consolidation projects
19
3# Install Energy-Efficient Cooling Units traditional data center design called for bulky computer room air conditioners (CRAC)units that are placed on the perimeter of the floor to move large amounts of air around the data center in-row or supplemental cooling units have been shown to save energy, typically enclose a row or two of servers, and the backs of all the servers are pointed into a single “hot” aisle Heat in the aisle is contained by a roof and end-row doors, allowing cooling to be applied directly to the heat source 20

4# Measure and Optimize We need metrics that businesses can use to measure the power-usage effectiveness of facilities infrastructure equipment identify areas where infrastructure optimization can achieve increased efficiency by simply monitoring and measuring their existing infrastructure equipment metering specific equipment racks or types of equipment such as servers can provide valuable insight into which specific consolidation, virtualization, and optimization projects will yield the best ROI 21
5# Implement Efficient Applications and Deduplicate Data Software and application efficiency can be significant for green IT Example: procedure for creating a data warehouse report was reduced from eight hours to eight minutes merely by changing the Oracle data warehouse search procedure Data deduplication(often called intelligent compression or singleinstance storage) is a method of reducing storage needs by eliminating redundant data

6# Make Use of Rebates and Incentives utility providers offer rebates or other incentives that encourage businesses to update equipment and adopt efficient operational practices that can help reduce peak and total power demands

Sulit menerapkan konsep green IT Green IT adalah mengenai daya listrik dan uang, meningkatkan halangan untuk berbisnis, menyempitkan pasar, dan membedakan produk Green IT bukanlah masalah teknik, tetapi masalah ekonomi yang harus dituntaskan

Manajemen Rantai Pasok (Supply Chain Management) SCM menggambarkan suatu pergeseran paradigma dalam manajemen bisnis modern dengan mengakui bahwa bisnis secara individual tidak lagi berkompetisi sebagai entiti tunggal, melainkan sebagai rantai pasok yang terdiri dari beberapa bisnis individual yang saling bekerja sama
29
Green Suply Chain Kunci utama dalam melakukan efisiensi pada rantai pasok adalah informasi Informasi yang cepat, tepat dan akurat memungkinkan proses bisnis berjalan lebih baik dan efisien

Lingkup TI dalam Rantai Pasok Berkaitan dengan perkembangan sistem informasi itu sendiri: 1. LEO (1951) 2. Business intelligence (1958) 3. Sistem real-time (1970) 4. Enterprise resource planning (2001) Namun demikian sistem di atas tidak mendukung koordinasi inter-organisasi (antar organisasi)
