Reverse osmosis (RO) technique is one of most efficient methods to desalinate the salt water. An accurate and detailed experimental method was established to analyze the performance of the unpotable water RO process, which is the solution-diffusion and mass transfer theory. The RO is going to be operated using an alternative energy source, solar energy. The solar cells are utilized to run the RO unit with a single vertical membrane. DC current is produced by a solar panel which produces 18 maximum volt and 4.25 maximum DC current. The solar panel was utilized to run out the DC booster pump without using an inverter. The production of freshwater is the major studied parameter in this project with other parameters, such as the efficiency of the RO unit and the salt rejection percentage (610 max PPM). The experimental work provides a more detailed understanding of solar RO unit in order to be utilized in the remote areas.

The need for energy sources today is very urgent required a variety of products that support the performance of humans today. At this time more and more developed source of energy or alternative energy source. one of them is using solar power. Many built solar cell modules that can absorb solar energy and convert it into a source of electricity or energy that can be used in everyday life. The purpose of this research is to design and analyze the making of solar cell module which is expected to expend the minimum cost by using Matlab simulation. The making of this solar panel module will be simulated first with Matlab Simulation Program where here we can design and analyze the calculations Generally used in making module from solar cell how efficient the model and also can reduce the cost of making solar cell. The manufacture of solar panel module simulation is intended to determine the maximum working point of solar panels. In the module by utilizing two solar panels that have an irradiance value of 1000 at a temperature of 25 ⁰ C capable of generating power of 61.2 Watt

Alternative Power

Energy that comes from the sun is energy without limits and never runs out. This energy is alternative energy that can be converted into electrical energy, namely by using solar cells. But people who live in remote areas will have difficulty getting electricity. Solar panels are an alternative power source. Solar panels are an alternative way to produce electricity. The production of good solar panels is an important thing that must be done to produce the desired electrical energy. The uncontrolled production process causes various types of defects that appear in solar panels. This study applies the Bayes theorem to classify data by estimating the probability that tuple X is in a class. Using thirty samples consisting of fifteen images of undamaged solar panels and fifteen images. The level of accuracy of image processing for identification of flawed solar panel textures by the Naive Bayesian Classifier method or Simple Bayesian Classifier is around eighty three percent. The results of this study are expected to be used as a reference for the initial detection system of damage that occurs on the surface of the Solar Panel

Abstract Re-Design Stalled Water Pump in Middle Siberut sub-district to be used again by using solar panel as an alternative energy source. Solar Panels used in this re-design are 48 pieces with capacity 200 WP. Energy produced from solar panels is stored in batteries with capacity 48 volts 400 Ah. Electrical equipment used is still alternating voltage, an inverter is needed so that can change the voltage in the same direction produced on solar panels be alternating voltage which will then be used as a source of electrical energy for activate water pump as well as other electrical equipment.

Biogas technology is an important alternative energy source worldwide. Blackwater and kitchen refuse represent ideal waste streams for bioenergy recovery through anaerobic co-digestion. Modeling of the biokinetics of anaerobic digestion on several aspects, such as microbial activity, substrate degradation, and methane production, from co-digestion of black water (BW) and kitchen refuse (KR) was the objective of this research. A mathematical model was developed towards a simulation based on mass balances on biomass, the organic substrate, and biogas. The model was implemented in INSEL and experimental data from the literature were used for model validation. The study shows that the simulation results fit well with the experimental data. The energy consumption and generation potential of anaerobic co-digestion of BW and KR were calculated to investigate if the produced biogas could supply the digester’s energy demand. This study can be used to pre-design anaerobic digestion systems in eco-districts.

This paper presents a concept for desalination by reverse osmosis (RO) using a vapor-trapping membrane. The membrane is composed of hydrophobic nanopores and separates the feed salt water and the fresh water (permeate) side. The feed water is vaporized by applied pressure and the water vapor condenses on the permeate side accompanied by recovery of latent heat. A probabilistic model was developed for transport of water vapor inside the nanopores, which predicted 3–5 times larger mass flux than conventional RO membranes at temperatures in the range of 30–50°C. An experimental method to realize short and hydrophobic nanopores is presented. Gold was deposited at the entrance of alumina pores followed by modification using an alkanethiol self-assembled monolayer. The membranes were tested for defective or leaking pores using a calcium ion indicator (Fluo-4). This method revealed the existence of defect-free areas in the 100–200 μm size range that are sufficient for flux measurement. Finally, a microfluidic flow cell was created for characterizing the transport properties of the fabricated membranes.
