Abstract

Water has become a vital necessity for every living organism to survive, leading to a threefold increase in global freshwater usage over the past 50 years. However, only 2.8% of the Earth's surface water is freshwater, while the rest is seawater. Therefore, seawater is processed into clean freshwater through desalination methods to make it consumable for the public. The desalination process involves two stages: evaporation and condensation aided by heat energy from a heater plate and a vacuum system. The use of vacuum in the desalination device aims to accelerate evaporation. In this study, three vacuum pressure variables were tested, namely no vacuum, 1 inHg vacuum pressure, and 2 inHg vacuum pressure. Data will be collected every 5 minutes for a total duration of 30 minutes for each variable. The research findings indicate that desalination using a vacuum system significantly affects the evaporation rate and the amount of freshwater obtained from the condensation process.

Abstract

Indonesia, the largest archipelagic country in the world, possesses a vast marine area. Despite being surrounded by the sea, many coastal communities in Indonesia lack access to clean water. Seawater distillation presents a viable solution to this scarcity. This process involves separating salt from seawater to produce fresh water. This study aims to analyze the effect of nozzle spray pressure on the evaporation process of seawater to optimize fresh water production. Experiments were conducted using a fogging nozzle with a diameter of 0.3 mm, varying the nozzle pressure at 40 psi, 70 psi, and 100 psi. The data were statistically analyzed to determine the impact of nozzle pressure on seawater evaporation. The results indicate that the highest evaporation occurred at a nozzle pressure of 40 psi, yielding 10 g of condensed seawater, whereas the lowest evaporation was observed at 100 psi, producing 4 g.

Abstract

Religious moderation between the younger and older generations shows that both have unique characteristics and challenges. The younger generation, with an innovative spirit and access to information, can become agents of change that encourage tolerance and understanding between religious communities. Meanwhile, the older generation has experience and wisdom that are important to be used as a basis in efforts to strengthen religious moderation, the spirit of religious moderation to find common ground in religion. The method of this research is qualitative, data collection is interview, observation, and documentation. Seber data is the older generation and the younger generation to find and search for definitions related to research phenomena. The analysis technique used is the Descriptive Analysis technique. The results of the study show that the comparison shows that there are differences in religious moderation attitudes between generations. The younger generation is more inclusive, tolerant, and open to differences, which is largely influenced by interfaith interactions on social media. In contrast, older generations tend to maintain more conservative views, both from a religious perspective and the needs of life. The implication of this research is to understand the differences in mindsets and approaches to religious moderation between generations, so that it can be the basis for cross-generational dialogue programs to strengthen social harmony, Religious education in schools and religious institutions can adjust teaching methods to be more relevant to the needs of each generation.
