Abstract

Global warming has become an increasingly important issue around the world today due to the rise of anthropogenic greenhouse gases emission, which gives several negative impacts on human life. There are some techniques have been studied and assessed i.e. physical mechanism by injected CO2 to the geological formations, chemical mechanism with artificial tree technology and biological mechanism by increasing the primary production through iron enrichment in high nutrient-low chlorophyll (HNLC) waters as well as mixing of water column below the sea surface. Those technologies, which are well known as Carbon Capture Storage ‘(CCS) technology, are expected to be applied to reduce the oncentration of anthropogenic CO2 in the atmosphere and to minimize the global warming. The Center of Environmental Technology, Agency for the Assessment and Application of Technology (BPPT) will carry out a research concerning CO2 reduction by a phytoplankton culture in a photobioreactor in three years. The main objective of this research is to assess the CO2 uptake capability of tropical phytoplankton. In this paper, we would showed the creteria and design to assembly a photobioreactor esspesially a air lift photobioreactor. To improve performance photobioreaktor, the materials included design criteria and the dynamics of fluids in fotobioreaktor have to considered propoerly. Other the hand, the selection of the most productive species and selection of appropriate media and economically also important to be done. Keywords: global warming, creteria and design, greenhouse gas, air lift photobioreactor

Abstract

The aim of the study is to create double-function equipment comprises the use of a dryer in the rainy seasons and of water distillation in dry seasons. The main components consists of a windmill as the sources of mechanical power to move the blower or water dipper and a drying room doubling as a distilling room by solar energy.

Abstract

This study delved into the viability of biomethane as a cleaner alternative to fulfil Jakarta's substantial cooking energy needs, which is currently reliant on liquid petroleum gas (LPG). By harnessing waste streams from wastewater, organic waste, and crop residues in an anaerobic digester, biogas was produced and subsequently upgraded into biomethane. Sodium hydroxide (NaOH) was utilized to enhance biogas production efficiency. Biomethane production amounted to 1.58 million tons annually, covering approximately 68.74% of the cooking energy demand. Although this falls short of Jakarta's annual LPG demand of 2.88 million tons, the study proposes a distribution scheme to bridge this gap and facilitate the broader adoption of biomethane. This research underscores the potential of biomethane in reducing LPG dependency, offering promising avenues for sustainable urban energy solutions.
