Judul: Aktivitas Fisik, Pola Konsumsi Pangan, Status Gizi dan Tekanan Darah Hubungannya dengan Kadar Asam Urat pada Peserta Lansia Wanita Posbindu Bukit Duri Jakarta
Abstrak: Penelitian ini bertujuan untuk menganalisis hubungan antara aktivitas fisik, pola konsumsi pangan, status gizi dan tekanan darah dengan kadar asam urat pada peserta lansia wanita Posbindu Bukit Duri Jakarta. Desain studi yang digunakan yaitu cross-sectional study dengan jumlah contoh sebanyak 60 orang lansia wanita. Teknik pengambilan subjek yang digunakan adalah purposive sampling. Subjek adalah wanita usia lanjut ≥ 60 tahun, memiliki pendengaran yang baik, dapat diwawancarai, tidak mengonsumsi alkohol dan dalam keadaan sehat. Penelitian ini dilaksanakan pada Maret – Mei 2015. Hasil penelitian menunjukkan kadar asam urat contoh 68.3% tergolong normal dan 31.7% tergolong tinggi. Lebih dari setengah (56.7%) status gizi contoh tergolong normal. Sebagian besar contoh (61.7%) memiliki aktivitas fisik tergolong ringan dan 35% contoh memiliki tekanan darah tergolong hipertensi II. Berdasarkan uji korelasi spearman terdapat hubungan signifikan (p<0.05) antara aktivitas fisik, status gizi, tekanan darah, tingkat kecukupan vitamin C dan frekuensi konsumsi nasi dengan kadar asam urat. Tidak terdapat hubungan yang signifikan antara tingkat kecukupan energi, protein, lemak, karbohidrat dan asupan purin dengan kadar asam urat.

Judul: Hubungan Pola Konsumsi, Status gizi dan Aktivitas Fisik dengan Kadar Asam Urat Lansia Wanita Peserta Posbindu Sinarsari
Abstrak: Arthritis is one of the diseases that are often found in women aged 55-70 years who often occured after menopause. The purpose of this study was to analyze the relationship between consumption patterns, nutritional status, physical activity with levels of uric acid in older women. Study design used in this study is a cross-sectional design. The sampling of this reasearh is 48 elderly people ≥50 years. There was significant difference (p<0.05) on age of menopause among the samples of normal and high uric acid level. There was no relationship between water consumption, coffee drinking habits, consumption of energy, carbohydrate intake, protein intake, fat intake, purines intake, nutritional status, physical activity and exercise habits with uric acid levels in the sample. There is a relationship between age at menopause with high levels of uric acid in the sample (p<0.05).

Judul: Penggunaan Teorema Homeomorphy 2-Manifold dan Teorema Euler Poincare pada Torus 𝑇�� dan Simplicial Complex 𝐾��
Abstrak: Two dimensional topological spaces are said to be homeomorphic if they have the same topological invariant, where one of topological invariant used is an Euler characteristic. Homeomorphy 2-Manifold’s Theorem and Euler Poincare’s Theorem are used to distinguish two topological spaces. Homeomorphy 2-Manifold’s Theorem uses Euler characteristic to identify two dimensional topological spaces. Euler Poincare’s Theorem is an alternative way to find Euler characteristic with Betti number, which is topological invariant as well. The objective of this paper is to investigate the homeomorphism of torus 𝑇����� and simplicial complex 𝐾�����. Topological space torus and simplicial complex 𝐾����� have the same Euler characteristic, which is two. Based on Homeomorphy 2-Manifold’s Theorem topological space torus 𝑇����� and simplicial complex 𝐾����� is homeomorphic.
