Empty fruit bunch (EFB) is one of the abundant biomass waste from oil palm and it is an issue that it can be used as renewable energy in the form of Bio-oil. Bio-oil is produced by a thermal cracking process. This research aims to identify the potential environmental impact of Bio-oil production from EFB as fuel. Life Cycle Assessment (LCA) with gate to gate approach is used in data processing applications for networks in Simapro V.9 and the database used is similar to the characteristics of the eco invent database. Functional units are used to show environmental references in impact categories, such as energy used and global warming potency. The results show that the stage of the bio-oil production cycle in the pretreatment process has a greater global warming impact than the others, amounting to 131.10013 kg CO2 eq. The results of the analysis using the networking graph on the Simapri, show that the environmental hotspot of the thermal cracking process for Bio-oil production is caused by the use of electricity from the State Electricity Company (PLN) and the release of chemical substances from the process. From the results of the LCA, environmental performance improvement or continuous improvement can be done is by managing energy use and installing equipment.

Eco-enzyme is a multifunctional liquid produced from fermentation of waste or organic waste, brown sugar or granulated sugar, and water. Fermentation of eco-enzymes is carried out for ±3 months. The length of time fermentation affects color, aroma and pH. The resultingeco-enzyme liquid is dark brown and has a strong fresh sour aroma. Eco-enzymeliquid has an alcohol content and acetic acid. Alcohol and acetic acid are produced from the bacterial metabolic process that is naturally present in the rest of fruits and vegetables. Variations in the fermentation time of eco-enzymes used are 2.5 months and 3 months. Analysis conducted on eco-enzymes include pH tests and phytochemical screening tests. The pH value obtained in eco-eznyme 2.5 months is 3, while the pH value in eco-eznyme 3 months is 1.5. Eco-enzymes with a fermentation time of 3 months contain alkaloid compounds, flavonoids, saponins, and tannins. In this study Eco-eznyme was used as a hand sanitizer spray by diluting the eco-enzyme with aquadest. The dilution ratios used vary for each sample: 1:40, 2:40, 3:40, 4:40, 5:40. Analysis conducted on hand sanitizer spray include pH test, organoleptic test, and antibacterial activity test. Based on the results of the analysis, not all hand sanitizer samples meet SNI standards, the best samples obtained in hand sanitizer with an eco-enzyme fermentation time of 3 months and a dilution ratio of 5: 40. The results of the analysis showed that the value of pH 5, the level of aroma fondness in hand sanitizer 2.40, the favorite color level 2.46

Empty fruit bunches of Palm Oil (EFB) are a potential source of biomass energy because they contain lignocellulose (cellulose, hemicellulose and lignin) so that they can be converted into biopellets for co-firing. The purpose of this research is to determine the raw material properties of EFB in the form of proximate, ultimate, lignin, and biopellets. Using a pelletizer, biopellets are created by adding starch as an adhesive. The raw material characteristics of EFB from proximate analysis revealed moisture content of 11.98%, ash content of 6.53%, volatile matter content of 65.15%, and fixed carbon content of 16.44%. According to the final study results, the biopellets from empty fruit bunches included 48.53% C, 6.05% H, 0.32% N, 36.8% O, and 0.08% Sulphure. The atomic ratio obtained from the final analysis results could be used to determine the calorific value that can be used for fuel; the biopellet calorific value of EFB is 4,583 kcal/kg, with Hardgrove Grindability Index (HGI) values of 78.6 and Ash Fusion Temperature (AFT) 1100oC. The lower the value of the atomic ratio contained, the higher the calorific value contained in a specific fuel.
