PENINGKATAN PRODUKTIVITAS DAN LINGKUNGAN DENGAN METODE GREEN PRODUCTIVITY PADA UMKM SALAK LERENG MERAPI

The current production process for processing snake fruit does not pay attention to water use efficiency, resulting in excess water use. Another problem that occurs is the large amount of liquid waste, which causes a strong odor and pollution of the water. One approach that can be taken to increase productivity while reducing environmental impacts is the Green Productivity (GP) model. The average value of productivity in the period January - September 2024 is 148.07% and the EPI Index is -27.50. In this research, efforts were made to handle liquid waste by proposing two alternative solutions. Alternative 1 is by adding a salak fruit mixer machine for efficient use of water and alternative 2 is by processing waste into biogas. Based on the alternatives proposed, alternative 2 was chosen as an alternative solution, namely making a liquid waste processing plant into biogas. This alternative was chosen because it can increase company productivity to 152.32% or provide a contribution of 4.25%. Alternative 2 also contributes to changes in liquid waste levels of the BOD5 variable by 89.70%, COD by 88.28%, TSS by 79.83%, as well as increasing the pH value by 61.59% so that environmental performance is better with an EPI index of -2.64.
