Obesity or overweight is a condition that occurs when the quantity of body fat tissue compared to total body weight is greater than the normal state. Diet, exercise, psychological factors, heredity, hormones, and drug side effects are a few of the factors that might cause obesity. Gastric heat syndrome was present in the patient in this case study. The patients received electrostimulator-assisted acupuncture treatment 12 times for a total of 15 minutes at the following points: Fenglong (ST40), Neiting (ST44), Sanyinjiao (SP6), and Quchi (LI11), and was also given the herbal remedy rosemary (Rosmarinus officinalis L.) for 28 days, taken twice daily. Through the activation of PPAR- g, inhibition of prankeas lipase, and inhibition of pre-adipocyte development into adipocytes, carnosic acid, a component of rosemary, helps people lose weight. Additionally, carnosic acid stimulates the excretion of fat in feces. According to the case study results, the patient's body weight dropped from 77.6 kg to 73.9 kg. This indicates that acupuncture treatments at the points Fenglong (ST40), Neiting (ST44), Sanyinjiao (SP6), and Quchi (LI11) together with the administration of rosemary herbs can result in weight loss of up to 3.7 kg over the course of 28 days.

Tuna (Thunnus thynnus) is a food that is often consumed raw to support raw food diet activities, so it has the potential to be contaminated with Salmonella typhi bacteria. Fish can be contaminated by bacteria due to their high water and protein content. Indonesia is the world's main tuna producer. Salmonella typhi detection in fresh tuna in Indonesia must be negative for Salmonella microbial contamination in order to meet food safety requirements. Microbial testing has drawbacks, such as long delays. An electronic nose was used to detect Salmonella typhi bacteria in tuna fish. The sample used consisted of 3 kinds of samples: Salmonella typhi bacteria, tuna, and tuna with Salmonella typhi contamination. The research was conducted with a shelf life of 48 hours and a sensing period every 6 hours with a sensor array of 8 sensors. The sensor output data is processed using the PCA (Principal Component Analysis) method. Through the PCA method, each variation of bacterial treatment can be classified. The result of the cumulative percentage variance of the two main components (PC) in the classification test between Salmonella typhi, tuna, and tuna with Salmonella typhi bacteria contamination was 90.5%. The most influential sensors in this study are TGS 825 for PC1 with a loading value of 0.625 and TGS 826 for PC2 with a loading value of -0.753. Therefore, it can be concluded that an electronic nose can classify between pure tuna and tuna contaminated with Salmonella typhi bacteria.
