Life Cycle Analysis of Wajik Salak Products on Five MSMEs in the Turi Agrotourism Area

Abstract

Measurements of energy, emissions and liquid waste can show the magnitude of the contribution of the wajik salak production process to potential environmental impacts. This study used 5 MSME objects which were carried out in the Turi Agrotourism Area, Sleman, Yogyakarta, research data started from July 2021-June 2022. The unit function used was 1 kilogram of packaged wajik salak products with a cradle to gate limit. Analysis was performed using OpenLCA 1.11.0 software with database support from Agribalyse v301. Based on the results of the analysis, it can be seen that of the five SMEs studied, the impact on the plantation stage was dominated by GWP with the largest value in UMKM E, namely 9.6149 Kg CO2 eq. The hotspot of the life cycle assessment of wajik salak products in modern wajik salak SMEs and traditional wajik salak SMEs is located at the plantation stage. Then from the three types of packaging analyzed for the four categories of impact on the five studied SMEs it was concluded that, the biggest impact was the GWP impact of plastic packaging on UMKM E 0.339 Kg CO₂ eq, the eutrophication impact came from woven bamboo packaging on UMKM D 5.9x10^{- 4} Kg PO₄^3- eq, then the acidification impact is caused by plastic packaging on UMKM E 1.25x10^-3 Kg SO₂ eq and the ODP impact of this type of woven bamboo packaging on UMKM D with a value of 1x10^-8 Kg CFC-11 eq
