Abstract

Institut Teknologi Sumatera (ITERA) is a new campus located in Lampung province- Indonesia. It is almost 6 years old, within large data on the total population human activity in this 275-hectare campus around 9500 persons, so that necessary to forecasting energy demand in the future, ITERA can project programs that are in line with the Indonesian government, specifically increasing using of renewable energy. which the government has a national energy policy in 2025 of 23%. Mostly in Lampung province, the electricity produced is still dominated by fossil energy (e.g., coal, diesel, etc), therefore as a campus with a technological background, ITERA must be able to bring a paradigm shift to be used from electricity consumption in the surrounding areas. The results of this study will project electricity usage in ITERA over the next 5 year, where electricity usage in ITERA 2019 is 2.472 GWh or 6,775 KWh/day, expected with a development strategy to implementing the efficiency of green energy, so that can meet the challenges of reducing CO2 emissions and energy-saving behavior, also keep sustainable impact for Indonesia.

Abstract

ITERA (Institut Teknologi Sumatera) is one of young university situated in Lampung Province, Indonesia. In 2018, the average population of campus (students, faculties, and staff) was about 9584 persons. The objective of this paper is to inventory Green House Gasses (GHGs) and then to calculate carbon footprint using equation by UI Greenmetric Guideline 2018 except for fuel and LPG consumption, paper use, and organic waste generation by using GHGs Protocol. Three scopes of GHGs emission were used to classify based on both direct and indirect source(s). The first scope was presented by LPG consumption and fuel consumption of campus’s car. Electricity consumption became scope 2 while the scope 3 involved paper use, organic waste generation including food waste and Yard trimmings, and transportation activities of both motorcycles and cars. The estimated GHGs emission was about 2846.541 metric ton CO2eq during 2018-2019 (one year) with the portion of each scope resulting 10.2%, 62%, and 28.2%, respectively. Electricity usage was being the highest contributor of carbon footprint. The inventory of GHGs will help top management of campus to evaluate and determine some strategies for minimization, reduction, and mitigation notably in electricity sector by some strategies such as substituting electric devices into eco-friendly products, applying energy management ISO 50001, and others.
