Judul: Tinjauan Sistematis dan Edukasi Gizi Berbasis Whatsapp Group untuk Pra-Lansia dan Lansia: Manfaat Kelor dalam Mengatasi Asam Urat
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. The results of the analysis using the Wilcoxon test on knowledge category, there was

Judul: Pengaruh pemberian kapsul dan teh daun kelor (Moringa oleifera) terhadap kadar asam urat lansia
Abstrak: Daun Moringa oleifera telah terbukti memiliki sifat antimikroba, anti-inflamasi, antikanker, hepatoprotektif, antihipoglikemik dan antioksidan. Asam urat merupakan produk akhir metabolisme purin yang kemudian dikeluarkan tubuh melalui urin, feses, dan keringat. Jika kadar asam urat dalam darah tinggi (hiperurisemia) peranannya dapat beralih menjadi pro-oksidan serta menyebabkan terjadinya endapan dan pengkristalan asam urat pada persendian yang akan menimbulkan peradangan sendi (gout). Hiperurisemia dipengaruhi oleh aktivitas enzim xantine oxidase. Tujuan umum dari penelitian ini adalah menganalisis pengaruh kapsul dan teh daun kelor terhadap kadar asam urat lansia. Sejumlah 24 subjek berpartisipasi penuh dalam penelitian ini, dengan karakteristik sebagai berikut; berjenis kelamin perempuan dengan kisaran usia 47-68 tahun, dikategorikan sebagai pra lansia dan lanjut usia dengan status perkawinan 70.83% menikah. Tingkat pendidikan subjek sebagian besar sekolah dasar (75%) dan tidak bekerja (58.3%). Sebagian besar subyek tinggal bersama pasangan/anaknya (58.3%). Memiliki jumlah anak lebih ≥6 orang (37.5%). Berdasarkan MNA, sebagian besar lansia (87.5%) masuk dalam kategori status gizi baik, 62.6% subjek memiliki riwayat medis menderita satu jenis penyakit, seperti hipertensi (66.7%). Kecukupan energi dan protein subjek sebagian besar dikategorikan defisit ringan yang diperoleh data nya dengan FFQ semi-kuantitatif. Sebagian besar subyek mengkonsumsi makanan yang mengandung purin pada tingkat sedang sebesar 66.7%. Ekstrak teh daun kelor (Moringa oleifera) memiliki aktivitas antioksidan (IC50) sebesar 88.9 ppm, total fenol sebesar 4.5 mg GAE/g dan flavonoid sebesar 2 mgQE/g. Sedangkan pada bubuk daun kelor memiliki aktivitas antioksidan (IC50) sebesar 78.5 ppm, total fenol sebesar 8.9 mg GAE/g dan flavonoid sebesar 3.6 mgQE/g. Hasil tersebut menunjukkan bahwa daun kelor mengandung antioksidan yang berpotensi untuk kesehatan. Analisis statistik menunjukkan ada penurunan yang signifikan (p<0.05) pada semua perlakuan yaitu kelompok kontrol, kapsul dan teh daun kelor. Pada hari ketujuh intervensi, penurunan terbesar terjadi pada kelompok yang diberikan kapsul kelor sebesar 1.75mg/dL, dengan kelompok yang diberikan teh daun kelor sebesar 1.14mg/dL sedangkan pada hari ke-14 intervensi, penurunan terbesar terjadi pada kelompok yang diberikan teh daun kelor sebesar 2.83mg/dL, diikuti kapsul kelor dengan penurunan sebesar 2.76mg/dL dan kontrol sebesar 1.35 mg/dL

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.
