Abstrak: SUMMARY SITI FATI HATUSSAADAH. A Systemic Review And Whatsapp group-Based Nutrition Education For Pre-Elderly And Elderly: Benefits Of Moringa Leaves In The Overcoming Of Uric Acid Levels. Supervised by CLARA MELIYANTI KUSHARTO, SITI MADANIJAH, and MIRA DEWI. Age and gender are factors that influence the increased risk of experiencing hyperuricemia (uric acid levels exceed normal limits), where the risk of hyperuricemia will tend to be high with age. A man is said to have hyperuricemia if his serum uric acid level is more than 7,0 mg/dL. Meanwhile, hyperuricemia in women occurs when serum uric acid levels are above 6,0 mg/dL. The elderly are grouped into two groups,1) pre-elderly, about 45-59 years old,2) elderly about >60 years old. Their nutritional needs are classified as active usually different from healthy adults. Aging has little effect on their health. This gave rise to the term “High-Risk Elderly” with criteria for age above 80 years who live alone, have depression, intellectual impairment, falling several times, urinary incontinence, and being unable to adjust in the past. The objective of this study were to analyze the benefits of Moringa leaves in the treatment of gout through systematic reviews, and provide nutritional education related to Moringa leaves in order to increased nutritional knowledge and motivation towards Moringa as alternative treatments for hyperuricemics through Whatsapp groupmedia. The Design of this study were systematic reviews design and one pretest and posttest design. The material for nutritional education was one of results from systematic reviews of some journals about Moringa in order to decreased uric acid levels in the body. Before and after intervention, subjects have given a pretest and posttest to evaluate nutritional knowledge and motivation of the subjects. The results showed that based on the Systematic Review method by searching using keywords, there were 313 articles. A total of 129 articles were excluded because based on the abstract their contents did not meet the criteria. There were 48 articles that were appropriate and relevant to the topic but 35 articles were excluded due to similar results, so that in the end there were 13 articles included in the analysis. The results of nutritional status from MNA, elderly have more percentage of risk nutrition status than pre-elderly. Based on the results of the analysis test in the knowledge category, it is known that the minimum score pretest is 14,30 and at the time post test is 57,10. Meanwhile, the maximum score of pre test is 71,40 and at the time post test is 100. This showed that there has been an increased in the subject's nutritional knowledge score after being given nutritional information through Whatsapp groupmedia. Then in the motivation category, it is known that the minimum score (pre test) is 14,30 and at the time post test is 71,40. Meanwhile, the maximum score of pretest is 71,40 and post test is 100. This showed that there has been an increased in the subject's nutritional motivation score after being given nutritional information through the Whatsapp group media.

Judul: The Effectiveness of Balanced Nutrition Online Education Using WhatsApp Application for Adolescents
Abstrak: Masa remaja merupakan masa perubahan yang berlangsung sangat cepat sehingga dapat menimbulkan masalah gizi. Salah satu cara dalam mengatasi permasalahan gizi pada remaja adalah edukasi gizi. Edukasi menggunakan aplikasi WhatsApp menunjukkan hasil yang baik. Namun, penelitian remaja di Jawa Barat masih jarang ditemukan sehingga peneliti ingin mengembangkan media edukasi gizi berupa edukasi online yang diberikan melalui aplikasi WhatsApp berdasarkan pesan gizi seimbang serta melakukan analisis pengaruh media edukasi gizi tersebut terhadap perubahan pengetahuan dan sikap remaja. Penelitian dilakukan dengan partisipasi 83 remaja yang sebagian besar subjek berjenis kelamin perempuan (63,9%), berusia 17 tahun (56,6%), berada dalam keluarga yang kecil (92,8%), dan memiliki status gizi yang normal (66,3%). Pemberian edukasi online dengan menggunakan aplikasi WhatsApp mampu meningkatkan pengetahuan (p=0,000) dan sikap (p=0,000) terkait gizi seimbang pada subjek. Analisis daya terima menunjukkan bahwa sebagian besar subjek menyatakan bahwa edukasi online yang diberikan cukup menarik (82,9%), durasi video cukup (97,6%), sangat mudah dipahami (80,5%), dan sangat mudah diakses (61%)., Adolescence is a period of rapid change that could cause nutritional problems. One way to overcome nutritional problems in adolescents is nutrition education. Education using WhatsApp application shows good results but research on adolescents in West Java is still rarely found. Therefore, researcher wants to develop nutrition education media in the form of online education provided through WhatsApp application based on balanced nutrition and analyze the effect of the nutritional education media on changes in adolescent knowledge and attitudes.

Judul: Bifurkasi Hopf pada Model Siklus Bisnis Kaldor Kalecki tanpa dan dengan Waktu Tunda
Abstrak: Business cycle model is one of dynamical system models in economic. One of the business cycles model is Kaldor-Kalecki model. Kaldor-Kalecki business cycle model that is written in delayed defferential equations, is a business cycle model that involves gross product and capital stock of a company. In this paper Kaldor-Kalecki business cycle model is analyzed using both nondelay and delay in time of capital stock. By Taylor expansion for the time delayed model, an analysis of stability around the fixed points has been done. Furthermore, by using Hopf bifurcation theorem, it can be shown that there exists periodic orbits and limit cycle. In the nondelayed model, changing the parameter of goods market could lead to the occurrence of Hopf bifurcation and the existence of limit cycle. Similarly, for the delayed model, it has been shown that changing the time delay parameter may result in the occurrence of Hopf bifurcation and limit cycle.
