Water is very important for all aspects of life on earth, agriculture is one of the fields that really need large amounts of water because of the use of water in the process of plant photosynthesis. Water that has good quality is if the water is not excessively polluted by harmful chemicals or minerals. One indicator that water is polluted is a change in temperature and pH (acidity) of the water. Temperatures that are too hot in the water will interfere with the growth of plants and other microorganisms. While the normal pH of water has a pH that ranges from 6.5 to 7.5. The quality of water and soil is very important in agriculture. The level of acidity (pH) and soil temperature are one of the things that affect plant fertility. Therefore, the quality of water and soil on agricultural land is one of the important things that needs special attention in its management. One solution so that water and soil quality can be monitored and managed efficiently is to utilize a Wireless Sensor Network based on the Internet of Things (IoT). The use of the ESP8266 Module as a WIFI module, is widely used by Internet of Things-based applications because the price is cheap so it reduces a lot of costs and has a fairly good speed of 80 MHz. This study aims to develop the concept of a Wireless Sensor Network by utilizing the ESP8266 module to monitor pH values using a pH Meter Analog Kit sensor and temperature from agricultural land using a DS18B20 Waterproof sensor and can be monitored at any time using a smartphone.

Skincare are very important for facial care. There are various skin problems one of which is premature aging and dull skin. The perpose of the writer is to know and explain the process making mangosteen skin serum and white rice as anti-aging and brightening, to find out and explain the benefits of mangosteen skin and white rice as anti-aging and brightening and to explain the public acceptance of the mangosteen skin serum and the white rice as anti-aging and brightening. the methoud used is observation, documentation, experiment, interview, questionares and literature. The third experiment produced the composition are 2ml glyserin, 1,5ml mangosteen extract, 1,5ml white rice extract, 5ml aquades, 0,5ml phenoxythanol, 1gr allantoin and 0,5g hydroxtethyl cellulose. Gives off the color beige, nice smell, thick texture and a moist application. After 14 times use, the face will feel moist, bright and fine line and wrikles on the faces are camouflaged. Based on public trials, the average output of 30 panels is the third product with an average of 3,43. The second product has an average of 3,26 and the first product hasan average of 2,93. Thus, it can be concluded that products could be the innovation of problems of premature aging and dull skin
