Abstract

The provision of food, energy supply, and the provision of information are The food provision, energy supply, and information delivery are controlled to improve people's welfare. In 2011, the national electricity production by PLN was 11% new and renewable energy. 6% hydropower and 5% geothermal. PLN plans the geothermal to be 13% and hydropower to be 6%. The availability of independent PhPP has been built by many communities. PhPP with a waterwheel drive provides a capacity of about 100 watts thus it is only enough for home lighting, whereas the hydro energy potential of the area is quite abundant. The development that has been carried out has several weaknesses; PhPP plump turbine type requires a high head which becomes a constraint for agricultural irrigation, in the other hand PhPP waterwheel type has low efficiency. The research was conducted to develop PhPP low head cross-flow turbine type, which is more efficient. The development begins with the experiment of the PhPP cross-flow turbine model to optimize the ratio of the diameter and width of the runner. A preliminary case study provides experimental results for a cross-flow turbine's torque and power parameters at a flow rate of 0.053 m3/s. Changes in the turbine diameter and width ratio are optimum at a runner width of 10 cm.

Abstract

The issue of biomass waste along the Ciliwung River and household waste, poses significant environmental risks. Chopper technology has emerged as a potential solution to convert plastic waste into valuable products, in this case, plastic pellets. This community service initiative aims to enhance participants' skills in operating and maintaining chopper machine, which is used to convert plastic bottle waste into plastic pellets. The training was conducted over one day with 20 participants from the Ciliwung Depok Community and residents in RW 02, Pancoran Mas District, Depok City. The activities included theoretical presentations, equipment demonstrations, hands-on practice, and evaluations through pre-tests and post-tests. Data were analyzed using the Paired Two Sample for Means method. The training demonstrated a significant improvement in participants' knowledge and skills, as evidenced by a statistically significant difference in the average scores of the pre-test and post-test (p-value < 0.05). The results indicate that the training had a substantial impact on the participants' abilities before and after the training. Similar programs are expected to be implemented in other communities to raise environmental awareness and promote the use of eco-friendly technologies.
