Abstract

This study aims to formulate or steps to produce a primus inter pares leader in the midst of a flawed democracy and to find out what factors hinder the birth of a primus inter pares leader from the electoral democracy process. The research method used is a descriptive qualitative research method through a case study approach. In determining the informants in the study, the researcher used a purposive technique. The data collection technique chosen was using observation, interviews, Focus Group Discussions (FGD), documentation checking the validity of the data using triangulation techniques. The results of the study are the formulation or steps to produce a primus inter pares leader in the midst of a flawed democracy and the factors that hinder the birth of a primus inter pares leader from the electoral democracy process are formulated aspects of the study and problems in realizing quality leader candidates, namely the problems of political parties, oligarchy, corruption and the rationality of society. In the aspect of political parties, a good party for the interests of society is called Good Political Party Governance which is able to provide a clear path for future leaders, who understand the values of democracy, integrity, and public service.

Abstract

Hydropower plants have limitations in scalability and location, as they require large water flows and complex infrastructure. One solution to overcome these drawbacks is portable hydroelectric power plants, which are more flexible and adaptable to variations in water level. Portable geothermal power plants allow the regulation of water fall height to optimise their performance, especially in remote areas that are not reached by conventional power grids. This research aims to develop the performance of portable geothermal power plants by utilising variations in water level to analyse the performance of the effect of water fall height on the performance of portable geothermal power plants with crossflow turbines. This research uses an experimental method, which involves collecting and analysing data from the height of (variation 1) and (variation 2) to determine the performance of the Pico Hydro Power Plant (PLTPh). The research was conducted at Mahogany Lake, University of Indonesia. The data collected includes measurements of voltage, current, power, and rotation speed of the turbine and generator at different altitude variations to determine the effect of water fall height on the performance of PLTPh with crossflow turbines. The results showed that the height of the water fall can affect the performance of the Pico Hydro Power Plant (PLTPh). At the height (variation 1), the power and output voltage generated are higher than the height (variation 2). In addition, the output voltage is also greater when the generator is operating without load. This difference shows that variations in altitude, flow speed and water discharge entering the turbine cross section greatly affect the rotation of the generator and the amount of electrical power generated by the PLTPh.
