Abstract

This study aims to analyze the effect of the use of multilevel gutters on the production volume and efficiency of the desalination system. The method used is an experimental method with two types of basins, namely a basin without a gutter (Basin A) and a basin with multilevel channels (Basin B). The test results show that the highest solar radiation intensity reaches 1409.77 W/m², which causes an increase in seawater temperature and evaporation rate. Freshwater production increases over the test time, with an average total distillate volume of Basin A of 1284 ml and Basin B of 971 ml. In Basin B, the condensate distribution shows that gutter II produces the largest distillate volume. The maximum efficiency obtained by each basin is 2.55% for Basin A and 2.05% for Basin B. In general, the use of multilevel gutters does not improve condensate distribution and does not increase the effectiveness of the condensation process.

Abstract

Referring to the International Energy Agency and the COP21 targets regarding carbon emission reduction and the depletion of fossil fuel reserves, hydrogen is one of the energy alternatives with high energy density. One of the hydrogen production methods is through water photolysis but is constrained by the high recombination of electrons e- and holes h+. For this reason, research was conducted to test this problem using a Multi-Wavelength Photoelectrochemical (MW-PEC) system that integrates photocatalytic and electrochemical. This study compares hydrogen production through electrolysis, photolysis, and MW-PEC combining both methods. The system works by containing 715 mL with KOH solution and the anode is coated with a composite as conductive. Meanwhile, a buck converter for power controller of UV-A LEDs and electrode plates as well as a blower for solution homogeneity. While at UV-C is constant with a function to conduct \(TiO_{2}\). Test results for 30 minutes, electrolysis produced HHO gas of 1.9 mL at 2.7 Vdc and 3.3 mL at 5 Vdc. For photolysis with 2.7 Vdc and 3.5 Vdc produced 1.5 mL and 1.8 mL. Meanwhile, MW-PEC produced 0.7 mL at 2.7 V and 1.3 mL at 5 V.
