Abstract

Indonesia's coffee production will reach 774.6 thousand tons in 2021, an increase of 2.75% from 2020, which was 753.9 thousand tons, and is the highest in the last decade and is expected to increase threefold in 2050. Hence, the evaluating environmental performance of the coffee agroindustry is essential if it is to become a more sustainable agroindustry. This paper aims to assess environmental performance (energy footprint, water footprint, and carbon footprint) in Gayo Arabica coffee green bean production with different agro-industry models. The method to evaluate environmental performance that can be used to identify indications of sustainability is Life Cycle Assessment (LCA) Method. The study was conducted on coffee production and exporter cooperatives in Central Aceh. Primary data were obtained through interviews with farmers, collectors, huller owners, and cooperative administrators. Secondary data comes from cooperative reports. The LCA study is described in two product systems, the model of 2015 and the model of 2016. The LCA model of 2015 is based on the green bean production system carried out in 2015 which includes water treatment, pulping, collecting, drying, hulling, finishing, and transportation. The LCA model of 2016 is based on the green bean production system carried out in 2016 until now which includes sub-processes for water treatment, pulping, collecting 1, hulling, collecting 2, finishing, and transportation. The results show that the energy footprint of the 2016 model (2.5128 MJ per f.u) is greater than that of the 2015 model (1.2336 MJ per f.u), the water footprint of the 2015 model is the same as the water footprint of the 2016 model product system, namely 0. 0086 m3 per f.u., and the carbon footprint of the 2016 model (1.93 kg CO2-eq per f.u) is greater than that of the 2015 model (1.48 kg CO2-eq per f.u). The cooperative initiative (in the model of 2016) is for the purpose of process improvement but cannot reduce carbon emissions. To reduce emissions from the use of fossil fuels, it is necessary to optimize land transportation routes and energy efficiency.

亚齐省Gayo Arabica咖啡绿豆的生命周期评估

2021年，印尼的咖啡产量将达到77.46万吨，比2020年的75.39万吨增长2.75%，是过去十年中的最高水平，预计到2050年将增长三倍。因此，如果咖啡农业要成为一个更可持续的农业，评估其环境绩效至关重要。本文旨在评估不同农产工业模式下Gayo Arabica咖啡绿豆生产的环境绩效（能源足迹、水足迹和碳足迹）。可用于确定可持续性指标的环境绩效评估方法是生命周期评估（LCA）方法。这项研究是针对中亚齐的咖啡生产和出口合作社进行的。主要数据是通过采访农民、收藏者、草包所有者和合作社管理人员获得的。次要数据来自合作报告。生命周期评价研究分为两个产品体系，即2015年模型和2016年模型。2015年的LCA模型基于2015年实施的绿豆生产系统，包括水处理、制浆、收集、干燥、去皮、精加工和运输。2016年的LCA模型基于2016年至今实施的绿豆生产系统，包括水处理、制浆、收集1、去壳、收集2、精加工和运输的子流程。结果表明，2016车型的能量足迹（2.5128兆焦耳/平方英尺）大于2015车型（1.2336兆焦耳/立方英尺），2015车型的水足迹与2016车型产品系统的水足迹相同，即0。0086立方米每平方英尺，2016年模型的碳足迹（1.93千克每平方英尺二氧化碳当量）大于2015年模型的（1.48千克每平方米二氧化碳当量）。合作倡议（在2016年模型中）旨在改进工艺，但不能减少碳排放。为了减少使用化石燃料的排放，有必要优化陆路运输路线和能源效率。
