Abstract

Plastic bag waste has the potential to be converted into alternative fuel oil through the pyrolysis method. This study applies the principle of thermal pyrolysis, conducted without oxygen, at the Edelweis Integrated Waste Management Site. The purpose is to analyze the characteristics of fuel oil derived from plastic bag waste based on parameters such as density, viscosity, calorific value, and acid number, as well as to estimate the potential fuel oil yield from plastic bag waste in Pontianak City. The results show that the density, viscosity, and calorific value of the produced fuel oil meet or closely approach standard requirements. However, the acid number measurements exceed the acceptable limits, 0.75 mg KOH/g for gasoline, 0.94 mg KOH/g for kerosene), and 0.50 mg KOH/g for diesel. This is likely due to high levels of chlorine (Cl) and silicon (Si) detected through X-Ray Fluorescence (XRF), which may originate from the plastic materials and red soil used as an adsorbent. Gas Chromatography-Mass Spectrometry (GC-MS) analysis confirms that the fuel oil contains hydrocarbon compounds similar to those found in commercial fuels, though in different proportions. Before the implementation of Circular Letter (CL) Number 43 of 2024, which prohibits businesses from providing plastic bags, the potential fuel oil production is estimated at 1,048,923.59 liters in 2024 and 1,259,375.52 liters in 2045. If this policy is fully implemented, fuel oil production is expected to decrease by approximately 16.52 percent in 2025 and 22.68 percent in 2045, due to the reduced use of plastic bags. This approach could be an effective way to reduce dependence on fossil fuels an estimated by 1 to 1.5 percent in 2025 and 0.8 to 1.7 percent in 2045. Although the results are promising, further testing is necessary to ensure full compliance with fuel standards.

Abstract

Peat contains high levels of phenols and lignin, which are resistant to decomposition. Drainage canals lower the groundwater table, promoting microbial degradation. This study investigated microbial decomposition in a secondary peat swamp forest by quantifying phenol-degrading bacterial colonies and measuring phenol concentrations in peat soil from Malikian Village, Mempawah Regency, West Kalimantan. Samples were collected from three plots at two depths, the aerobic layer and the anaerobic layer, with fifteen (15) samples from each depth. Bacterial colonies were counted via mineral salt medium (MSM) with up to five dilutions, whereas phenolic compounds were measured via the Folin–Ciocalteu method. Paired t-tests revealed highly significant differences in both phenol concentration (p-value < 0.001) and the number of phenol-degrading bacterial colonies (p-value < 0.003) between the aerobic layer and the anaerobic layers. These findings indicate that peat decomposition is more pronounced in the aerobic surface layer than in the permanently waterlogged layer. This observation is attributed to the greater number of phenol-degrading bacterial colonies and lower phenol concentration in the surface layer than in the deeper layer. Consequently, the aerobic conditions in the surface layer of the secondary peat swamp forest facilitate accelerated peat decomposition
