The Impact of 12 Weeks of Moderate-Intensity Aerobic Exercise on Reducing Obesity in Older Adults

Objective. Obesity is a significant health concern that can affect individuals of all ages, including children and adults. The purpose of this study is to evaluate the effectiveness of 12 weeks of moderate-intensity aerobic exercise in reducing complex obesity levels in older individuals. The research methodology used in this study is experimental, with a one-group pre-post test design. The study was conducted in June-July 2023 at the Jakarta State University Sports Hall, located in Rawamangun, East Jakarta. Following the participants' completion of 12 weeks of moderate-intensity aerobic exercise, a post-test was administered, which included measuring their BMI. Materials and Methods.  The study involved 30 elderly participants who were obese. The sampling technique used was purposive sampling, with several criteria such as being male, aged between 55-65 years, having a body mass index (BMI) between 27-32 kg/m2, coming from a large family from the Faculty of Sports Science, Jakarta State University, and being willing to participate in research on the effects of moderate-intensity aerobic exercise for 12 weeks. The research aimed to determine the effects of moderate-intensity aerobic exercise for 12 weeks on reducing the level of complex obesity in elderly people. Result. The research findings indicate that the 12-week program of moderate-intensity aerobic exercise, designed by researchers, is an effective approach to significantly decrease complex obesity in the elderly population. The results of the study demonstrate the potential benefits of engaging in regular physical activity to improve the health and well-being of older adults. Conclusion. The study results indicate that engaging in aerobic exercise of moderate intensity, such as running on a treadmill, for 12 weeks can lead to a significant decrease in body fat and weight, thus promoting effective obesity reduction.Objective.

UJI EFEKTIFITAS DAYA ANTHELMINTIK PERASAN BUAH SEGAR DAN INFUS DAUN NANAS (Ananas comosus (L.) Merr) TERHADAP Ascaridia galli SECARA INVITRO

Background : Pineapple (Ananas comosus (L.)Merr), a kind of fruit which is often consumed by people, can be used as a traditional medicine. Pineapple fruit and leaf have many functions,such as an anthelmintic. This research was aimed to prove that fresh pineapple fruit squeeze and pineapple leaf infuse have the anthelmintic potency by comparing with NaCl 0,9 % as negatif control and piperazin citrat (as positif control), as well as comparing anthelmintic potency between pineapple fruit squeeeze and pineapple leaf infuse. Methods : This research is an experimental research with post test only controlled group design. The sample were Ascaridia galli worms, which were taken randomly. The sample were treated with pineapple fruit squeeze in concentration 10%,20%,30%,40% and Pineapple leaf infuse was in the concentration of 25%, 45 %, 65 %,85%. Positif control was piperazin citrat in the concentrationm of 0,2% and The negatif control was NaCl 0,9% Liquid. Sample from each groups was replicated three times. Data were collected through the observation of total mortality in every hour. LC100 and LT100 was calculated by probit analysis. Result : Probit analysis showed that LC100 of fresh pineapple fruit squeeze at the concentration 47,775% and LT100 of fresh pineapple fruit squeeze was 665,529 minutes. Pineapple leaf infuse had LC100 88,629 % and LT100 of pineapple leaf infuse was 1119,951 minutes. Kaplan-Meier test showed that pineapple fruit squeeze 40% was the most effectif . Pineapple fruit squeeze had effectivity less than control positif . Conclusion : Pineapple fruit squeeze and pineapple leaf infuse have the anthelmintic potency to Ascaridia galli worms in vitro. Pineapple fruit squeeze has more effective anthelmintic potency than pineapple leaf infuse. Piperazin citrat is the most effective than pineapple fruit squeeze and pineapple leaf infuse. Key Words : Pineapple fruit squeeze, pineapple leaf infuse, anthelmintic potency, Ascaridia galli
