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.

The research involves optimizing process conditions such as temperature, pH, enzyme concentration, and fermentation time. The results indicate that rice washing wastewater has the potential to be an efficient raw material for bioethanol production. Thus, this study contributes to the development of renewable energy sources and the utilization of agricultural waste to create a more sustainable economic cycle.  

 Assessment of food consumption can be used to determine the amount and source of nutrients eaten. This can help show the supply of nutrients in the body that is sufficient or less regular with balanced nutrition that supports stamina and body health, especially for children. This habit supports physical and mental growth. Familiarizing children with healthy eating patterns is easy. Many parents complain about their children's poor eating habits, such as refusing to eat rice complete with side dishes, choosing only sweet foods or refusing to eat the same for various reasons. Of course it makes parents worry about the development of the baby (Luchan, 2014). The results of the research obtained, can be seen from research on 32 respondents about the relationship between diet and nutritional status in toddlers aged 1-4 years in Huta III Village Tanjung Pasir Simalungun Regency can be drawn as follows: Based on the largest frequency of eating respondents have a good frequency of eating as many as 25 people (78.12%), respondents have a frequency of eating that is not good that is 7 people (21.88%). Based on the portion of food the majority of respondents had a good portion of food, namely 21 people (65.62%), the portion of food that was not good was 11 people (34.38%). Based on the main food, respondents have a good type of food, namely 19 people (59.38%) and 13 people (40.62%).

Tape is a traditional fermented food whose benefits can be increased by adding probiotic cells such as Saccharomyces boulardii and Lactobacillus plantarum Dad-13. Tape tends to be easily damaged, so to maintain the viability of probiotics and as a food diversification, tape can be substituted for ice cream dough. The purpose of this research was to determine the effect of substitution and the proportion of substitution of glutinous rice and cassava tape in the manufacture of ice cream on the characteristics and preference level of probiotic ice cream. This research method was carried out using a completely randomized design with a factorial pattern with two factors, the first factor was the type of tape, and the second factor was the proportion of substitution. The type of tape used are white cassava tape, yellow cassava tape, white glutinous rice tape, and black glutinous rice tape with substitution proportions of 0%, 10%, 20%, 30%, and 40%. Analysis of probiotic sticky rice tape and cassava ice cream included water content, total solids, melting time, antioxidant activity, total lactic acid bacteria, total yeast, and preference level. The data obtained will be calculated using the Anova statistikal method. If there is a significant difference between treatments, it is carried out with Duncan's Multiple Range Test significant difference test at a confidence level of α= 5%. The results showed that glutinous rice and cassava tape types and their substitution proportions affected the water content, total solids, melting time, antioxidant activity, total lactic acid bacteria, total yeast, and preference level. Based on the preference level and antioxidant activity, the best ice cream was produced with the substitution of 20% white cassava tape or 20% yellow cassava tape, which had an antioxidant activity of 32.41% and 33.17% RSA and total lactic acid bacteria of 1.79 x 108 and 1.67 x 108 CFU/g, respectively.
