Abstract

This research aimed to examine the potential of waste from controlled landfills a raw material for a Waste-to-Energy (WtE) plant. The research employed the qualitative method with direct observation. Data were analyzed descriptively. The results showed that the composition of waste in Cirebon was mostly dominated by household food waste (52.41%), followed by plastic (15.58%) and paper (8.05%). Based on the amount of existing waste and the projected amount in Cirebon City and Cirebon Regency, the waste can potentially be used as raw material for WtE plant. The energy generated from this waste can be sold to PLN, creating a positive utilization of the waste. It is projected that Cirebon City will produce 1319 m3/day of waste, and Cirebon Regency will produce 4767.65 m3/day (1161.26 tons/day) in 2023. Therefore, further research is needed to develop appropriate, efficient, and environmentally friendly technology for the municipal solid waste management system in Cirebon.

Abstract

Cyanobacteria play an important role in the evolution of the earth and biosphere. Cyanobacteria play a role in the oxygenation of the atmosphere and oceans that began since the great oxidation event. These living things are the main producers in the ocean in the past and present and are the ancestors of Chloroplasts. The morphology commonly used is still difficult to read for microfossil interpretation which makes the identification of cyanobacteria in the early fossil record still ambiguous. This study was conducted to review classical and new cyanobacterial biosignatures. In addition, this study will also analyze the fossil record of cyanobacteria mentioned earlier and the challenges of molecular approaches to modern cyanobacteria. The suggestions we provide are new calibration points for molecular clocks and strategies to increase insight into the timing and patterns of cyanobacteria evolution and oxygenic photosynthesis.
