On a worldwide basis, freshwater is becoming increasingly limited, particularly in dry and distant regions. This presents a complex problem for regions such as islands, where the transportation of water that is suitable for drinking is expensive. In order to address this dilemma, the primary focus of the 21st century ought to be on boosting water purification through the use of renewable energy technology in the desalination industry. To be more specific, the incorporation of solar energy into the business has the potential to extend the lifespan of units, reduce expenses, and reduce the positive impact on the environment. The article contains a sufficient number of studies on a variety of passive and active stills, and it offers an understanding of the effectiveness of each form of still. Vacuum tube solar stills are more efficient than others. In addition to this, it investigates several approaches to cooling the glass cover and the elements that influence the productivity of solar stills, among which are environmental and design considerations. Resolving the problem of diminishing freshwater resources and integrating solar energy for water purification.

Salah satu masalah yang sedang dihadapi di beberapa daerah di Indonesia adalah air. Air merupakan sumber kehidupan yang digunakan untuk berbagai keperluan. Salah satu sumber air yang sering digunakan oleh masyarakat adalah sungai. Sungai merupakan salah satu habitat hidup air bagi sebagian makhluk hidup air tawar. Salah satu unsur kualitas air adalah tingkat kecerahannya. Air dengan tingkat kecerahan yang tinggi sangat memungkinkan terjadinya proses asimilasi dalam perairan. Tingkat kecerahan air sangat mempengaruhi proses fotosintesis fitoplankton. Tujuan dari kegiatan pengabdian kepada masyarakat ini adalah untuk membantu masyarakat Kelurahan BP. Nauli Kecamatan Siantar Marihat Kota Pematangsiantar dalam mengetahui tingkat kecerahan air sungai Bah Toge sehingga air sungai dapat dipergunakan untuk berbagai kegiatan yang menguntungkan seperti tambak ikan. Metode pelaksanaan kegiatan adalah memberikan pelatihan dalam pembuatan Secci disk serta penggunaannya. Dari hasil pengujian terhadap kecerahan air sungai Bah Toge diketahui bahwa tingkat kecerahan air pada sungai Bah Toge masih sangat keruh dengan tingkat kecerahan di bawah 50% dari kedalam air.

“…The problem of lack of clean water can be overcome if people have new ways to produce their own clean water. Data obtained from WHO shows that water consumption per human is between 60 and 120 liters per day and will even increase dramatically in the 20th century with consumption reaching 75-100 liters per day [2,3].…”

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.
