Judul: Konsumsi pangan sumber lemak, aktivitas fisik, status gizi, serta tekanan darah pasien lanjut usia di Rumah Sakit Salak Bogor.
Abstrak: Penelitian ini bertujuan menganalisis konsumsi pangan sumber lemak, aktivitas fisik, status gizi, serta tekanan darah pasien lanjut usia di RS Salak. Desain penelitian yang digunakan adalah cross-sectional study dengan jumlah subjek 18 lansia yang ditentukan berdasarkan metode non probability accidental sampling. Makanan sumber lemak yang sering dikonsumsi contoh secara berurutan adalah gorengan, telur ayam, susu, dan daging ayam. Asupan lemak seluruh contoh berada di kategori cukup (≤ 30% energi total). Contoh memiliki tingkat aktivitas fisik sangat ringan (66.7%) dan ringan (33.3%). Hasil uji statistik menunjukkan bahwa, terdapat korelasi yang signifikan antara usia dengan tekanan darah diastolik (p<0.05), demikian pula antara status gizi dengan tekanan darah diastolik dan sistolik (p<0.05).

Judul: Hubungan Konsumsi Pangan dan Aktivitas Fisik dengan Status Gizi serta Tingkat Kebugaran Lansia Peserta PUSAKA V Jakarta Pusat
Abstrak: Tujuan penelitian ini adalah menganalisis hubungan konsumsi pangan dan aktivitas fisik dengan status gizi dan tingkat kebugaran lansia peserta Pusaka V Jakarta Pusat. Desain penelitian ini adalah cross sectional study dan melibatkan 32 orang lansia. Konsumsi pangan dilihat dari makanan yang di konsumsi lansia. Aktivitas fisik didapat dari hasil wawancara. Tingkat kebugaran didapat dari hasil tes kebugaran. Hasil penelitian menunjukan rata-rata konsumsi energi contoh 1723 Kal. Rata-rata aktivitas fisik contoh tergolong ringan (87.5%). Status gizi contoh sebagian besar tergolong dalam kategori normal (46.8%), under weight (9.3%), dan over weight (43.7%). Hasil penelitian menunjukan bahwa terdapat hubungan yang signifikan antara konsumsi pangan dengan status gizi (p<0.05). Ada hubungan yang signifikan (p<0.05) konsumsi zat gizi (energi, karbohidrat dan fospor) dengan tingkat kebugaran (chair sit and reach dan back scartch).

Judul: Hybrid solar cells of ZnO nanoparticles/chlorophyll was modified metal ions (Zn2+ and Cu2+ )
Abstrak: Zinc Oxide (ZnO) is a n-type semiconductor with a wide the energy band (Band Gap) is 3.37 eV at room temperature and 3.34 eV at low temperature with a large exiton binding energy is 60 meV. ZnO has been synthesized by hydrothermal method, resulting in a decrease in particle size over the duration of the hydrothermal changes. Crystallographic structure of ZnO were characterized using XRD, has shown the characteristic pattern of a hexagonal wurtzite structure, the crystallite size increases to changes in particle size. Changes in particle size has also led to a change in the absorption peak of ZnO as has been demonstrated posted under test using the optical properties of UV-Vis spectrophotometer. Changes of this uptake has also led to changes in the energy band gap, which increases its band gap energy of the particle size. In electronic applications, especially in solar cells. Chlorophyll is considered less effective, because of their very nature are easily degraded as a result of several reactions which are acid, lighting and temperature. The results of the stability test using a halogen lamp 34 W/m2 for 5 hours, that the substitution of chlorophyll with metal ions Zn2+ and Cu2+ has been shown to form more stable than natural chlorophyll. The characterization of the optical properties, the combination of ZnO / chlorophyll in the form of hybrid films has led to a shift in the absorption region of ZnO becomes more widely from the UV to Visible. ZnO/chlorophyll has absorption range of 350-515 nm, ZnO / Zn-feofitin 332-401 nm and 332-632 nm for Cu-feofitin. The combination of ZnO/chlorophyll and CuSCN as a solid electrolite in hybrid solar cell, a modified chlorophyll with metal ions Zn2+ and Cu2+ has been shown to form a more stable I-V curve. It is characterized by its fill factor value greater than natural chlorophyll. Nevertheless, solar cells with natural chlorophyll has been able to produce higher efficiency values of chlorophyll were substituted.
