Recently, many hydroponic farms have emerged. This is due to the increasingly limited agricultural land and also as a way to fill time during the Covid-19 pandemic. In hydroponics, the role of water as a planting medium plays a very dominant role. This is because air is a solvent for the nutrients that plants need. So air is a key factor in poverty in the Hydroponic farming system. That need to be considered when choosing water for hydroponic cultivation is that it is based on the air acidity value. The air acidity value is important as a parameter that influences plant growth in the hydroponic cultivation method. The ideal temperature value ranges between pH 5.5-6.5. In Cangkringsari Village, Sukodono District, Sidoarjo Regency, Karang Taruna Tunas Cangkring has tried to develop hydroponic farming, but because the supply of acidic air with a pH that is not ideal causes plant growth to be poor. Therefore, an automatic control model for hydroponic irrigation is needed. The method developed uses the Fuzzy method. The Fuzzy method applied functions to control the air pump automatically, so that the Arduino Uno microcontroller and the 4502c pH sensor combined can detect the pH of the nutritious air that will be given to hydroponic plants in the range of 5.5 to 6.5. The application of the Fuzzy method can be applied to drive the nutrient pump perfectly so that with its application it can maintain the air pH in the specified range.

Sourdough is a mixture of wheat flour, water and other components processed by fermentation. Sourdough, in other terms, is natural yeast which can be used as a food additive for starters in making bread, cakes and other bakery products. The process of making sourdough can take place naturally through a fermentation process, resulting in a unique taste and aroma of bread and better nutritional content. However, currently natural sourdough yeast is being developed as a bread developer. This is because some Istan yeast can cause allergens if they enter the body and are consumed directly. The use of natural sourdough yeast is an alternative for developing whitebread. This research aims to determine the effect of different sourdough concentrations on the physical and microbiological properties of white bread. The method used in this research used a Completely Randomized Design (CRD) with one factor, namely sourdough concentration of 0%, 30%, 60% and 90%. Apart from that, the proofing time has been determined at around 135 minutes. The parameters observed were physical quality (expandability, texture), microbiology (total number of lactic acid microbes), and water content analysis. Data analysis uses ANOVA and if there is a significant difference then proceed with the Least Significant Difference test (LSD). The results of the study showed that the addition of sourdough had a significant effect on the physical, microbiological and water content of white bread. In addition, fermentation time has a significant effect on the number of natural sourdough yeast microbes. The natural sourdough yeast used to make white bread with a fermentation time of 16 days.
