Abstract

The pattern of food and medicine consumption among children is a crucial thing that is important for parents and teachers to pay attention to at school. It is very important to provide guidance and reinforcement regarding hygiene, sanitation or food safety to food makers, including parents and the implementation team or school canteen organizers. Based on the results of initial observations, it was found that the food presentation met standards, but there were still teachers who did not understand how to use cooking utensils correctly. The aim of this service is to increase teachers' knowledge in terms of providing nutritious and safe food and the use of medicines that are commonly given in the school environment. The method used in this service is providing material in the form of counseling. The results of the service showed that there was an increase in the knowledge of service participants after being given counseling material in the form of providing food and medicine in a safe and hygienic manner.

Abstract

Surface tension is an important physicochemical property that plays a major role in determining the interfacial behavior of a liquid in various scientific and industrial applications. Accurate surface tension measurement is required to understand liquid interactions, optimize formulation processes, and predict the stability of dispersed systems such as emulsions. This review article examines and compares several commonly used methods in surface tension measurement, namely the capillary rise method, the Du Noüy ring method, the drop and drop–weight/volume comparison method, the maximum bubble pressure method (MBPM), and micro-droplet measurement using Atomic Force Microscopy (AFM). Each method is analyzed based on its working principle, level of accuracy, advantages, limitations, and suitability for various types of liquids. The results of the review show that classical methods such as Du Noüy and the stalagmometer remain relevant because they are practical and easy to use, while modern methods such as AFM offer high sensitivity for micro-droplet samples. Overall, selecting the appropriate measurement method must consider sample characteristics, instrument availability, and analytical objectives. This review is expected to serve as a comprehensive reference for researchers, students, and industry practitioners in determining the most suitable technique for surface tension measurement.
