Solar distillation is a method of thermal desalination in which water is evaporated using solar energy and the separated water vapor is condensed again as pure water. This is a good practical alternative in offering a renewable energy source that is used to produce clean water in areas where there is a lack of clean water. This study aims to obtain the results of the amount of thermal energy obtained from a passive solar desalination system with a double slope and the factors that greatly affect the amount of thermal energy in the system. In this study, the method used for data collection was an experiment carried out for eight days. From the research results, the highest thermal energy produced is 9.18 kWh and the lowest is 1.23 kWh, and the factors that affect the amount of thermal energy are the heat transfer coefficient and the amount of distilled water produced by the system. By knowing the amount of thermal energy produced by the system, areas that have a lack of clean water can use a passive solar desalination system with a double slope that uses solar energy as its energy source.

“…The basic principle of desalination is to evaporate water into condensate. One of the factors that causes water to evaporate is by providing heat energy [4] [5]. The advantage of the water desalination used is that it is able to produce clean water that can be used to meet daily water needs such as drinking, cooking, washing and so on.…”

Solar desalination functions to filter water, both sea water and brackish water, to produce clean water that is fit for consumption with energy from the sun. Solar energy is a renewable energy source that has been widely studied for its use. One of its uses is in a double slope passive solar still where the sun is the main source. Energy and exergy obtained from solar energy are not all used to evaporate water in the desalination system, so it is necessary to calculate efficiency energy and exergy in the system. This study aims to obtain data on the amount of efficiency energy and exergy from the double slope passive solar still as well as the factors that affect efficiency energy and exergy. The results showed that energy efficiency was in the range of 30.20% to 55.15% and exergy efficiency was in the range of 0.93% to 5.36%. The factors that influence the amount of energy efficiency and exergy are solar intensity, basin area, basin cover area, amount of water produced and ambient temperature.

“…Temperatur dan kecepatan udara merupakan faktor yang memiliki pengaruh cukup besar terhadap proses pengeringan. Semakin tinggi nilai temperatur maka akan mempercepat proses pengeringan begitu juga sebaliknya, dan semakin tinggi nilai kecepatan udara sebagai konveksi paksa maka akan mempercepat proses pengeringan [5] [6].…”

Drying is a mass transfer and heat transfer process that is strongly influenced by temperature and air velocity. The importance of analyzing the temperature distribution and air velocity is expected to be used as a reference to optimize the drying process to be faster and better. This study aims to analyze the temperature distribution and air velocity that occurs in a coffee bean dryer with a forced convection system using CFD simulation. CFD simulations are carried out using ANSYS Fluent software. with steady conditions, and using a pressure-based solver method. The obtained temperature distribution occurs with an estimated absorber temperature difference with the drying chamber is 31% during the day.
