Electricity consumption in Merauke Regency increases every year in line with economic growth and population growth. Meanwhile, fossil energy reserves as fuel for power plants have decreased. To reduce dependence on fossil energy and offset the increase in electricity consumption it is necessary to develop alternative electrical energy sourced from renewable energy. Merauke Regency has great potential for renewable energy derived from biomass, solar, and wind. A study or analysis is needed to be able to estimate the energy potential that can be developed in an area. This study uses data collection techniques and analysis of the potential for renewable energy in Merauke Regency using RETScreen Expert. Analysis results show the potential of solar energy, and the most potential biomass energy to be developed.

The development of experiments to convert solar energy into electrical energy in photovoltaic (PV) has been widely carried out. Simulation is one approach that is used to find out the initial data before conducting an experiment with the aim of minimizing errors, saving design efficiency, time and budget. Simulation is made by modeling mathematical equations to analyze the performance of PV modules. The equation model is made into a block diagram, then simulated by the input-output function in Simulink Matlab. PV used is a type of amorphous silicon (a-Si). The Sun spectrum is the AM1.5 G standard which is concentrated using Fresnel lenses at wavelengths of 400-700 nm. Photovoltaic parameters include intensity, temperature, construction and materials taken from module specification data. Calculation analysis of PV modules produces a maximum total power of 0.057 W with efficiency reaching 6.68 %.

Merauke Regency is the largest regency in Papua with the highest fuel consumption by regency/city in Papua Province. The high fuel consumption is proportional to the emissions produced, so research on emissions absorbing media is needed to reduce emissions. Active charcoal has the ability to adsorption of emissions, one of the raw materials is plants. Bus wood (eucalyptus) which grows a lot in Merauke can be used as raw material for activated charcoal which is used as an absorber of emissions. Research with the title “application of eucalyptus charcoal as emission adsorbent to reduce vehicle exhaust emissions” processes wood logs into emission adsorbents, through carbonation and activation processes, then activated charcoal is applied to vehicle vehicles and subsequent emission tests, to determine emission reduction capabilities. Based on the results of emission tests, the use of activated charcoal as an emission adsorber can reduce emissions. 0.07% CO emissions decreased to 0.01%, HC emissions 84 ppm, decreased to 39 ppm, and 14.7% CO2 decreased 4.4%.

The production of sago starch in Papua is around 200 thousand tons per year, even though the potential is 4.75 tons of dry starch per year. The large potential for sago starch production cannot be realized optimally due to the low production capacity. The production capacity is doubtful because the sago processing process is still carried out traditionally. The problems encountered can be solved by applying machining technology to the sago production process. The application of technology in the form of production machines will improve the quality of sago starch and production capacity. The production capacity of sago starch can be increased through the application of technology in the production process. Especially the sago pith grating machine technology and sago starch extraction machine technology, because these two processes consume the most time when using traditional methods. The working principle of the sago starch extraction machine that has been made is that the rotation generated by the driving motor is channeled through the pulley transmission and the V-belt drives the gearbox, the rotation of the gearbox output shaft through the pulley transmission and the V-belt drives the stirring shaft. The production capacity of the sago extraction machine is planned to be 80 kg/hour. The design of the sago extraction machine uses wheels to facilitate the mobilization of the machine to the sago plantation area.
