Abstract

This study explores the novel effect of Extremely Low Frequency (ELF) magnetic field radiation on the ripening process of raw fermented tempe, a traditional Indonesian food made from soybeans. ELF magnetic fields are environmental factors that can influence the growth of microorganism activity. The study uses a unique laboratory experimental method that employs a Current Transformer (CT) device to produce an ELF magnetic field with an intensity of 500miu, which is a relatively high intensity compared to the natural background level of ELF magnetic field. The study examines 20 raw tempe samples, each weighing 100g, divided into two groups: a control group and an experimental group. The experimental group is exposed to the ELF magnetic field for 24 hours, while the control group is not. The study measures the changes in the microbial population, pH, moisture content, and sensory quality of the tempe samples after the exposure. The study aims to prove the effect of ELF magnetic field radiation on food security and to provide insights for the development of new food preservation techniques.

Abstract

The background of this study is based on the importance of urine as a health indicator, which reflects the body's metabolic condition and can identify the presence of abnormal or pathological substances. Urine contains various organic and inorganic compounds that can change depending on a person's health condition, such as diabetes or pregnancy. The objective of this study is to analyze the influence of bodily conditions on urine production and to identify abnormal substances in urine using various chemical tests. The research method involves testing urine samples from healthy individuals, pregnant women, and diabetes patients using pH, chloride, sulfate, phosphate, glucose, and albumin tests. The results of the study showed significant differences in urine composition between normal and abnormal samples, such as more acidic pH in diabetic urine and the presence of glucose and protein in certain urine. The implications of this study contribute to early diagnosis and health condition monitoring through urine analysis, as well as providing a basis for the development of more accurate and efficient examination methods.
