Judul: Aktivitas Fisik, Konsumsi, Status Gizi, dan Tingkat Kebugaran Atlet Remaja Taekwondo dan Gulat
Abstrak: Tujuan penelitian ini adalah menganalisis hubungan antara tingkat aktivitas fisik, tingkat kecukupan gizi, status gizi, dengan tingkat kebugaran atlet taekwondo dan gulat. Penelitian ini menggunakan desain studi kasus yang melibatkan 25 orang atlet taekwondo dan gulat. Penelitian dilakukan pada bulan Mei sampai Juni 2018 di PPOP DKI Jakarta. Data yang dikumpulkan terdiri atas karakteristik contoh, aktivitas fisik, konsumsi makanan, status gizi, dan tingkat kebugaran. Hasil uji korelasi Pearson antar variabel menunjukan bahwa terdapat hubungan yang signifikan antara tingkat aktivitas fisik dengan tingkat kebugaran (p<0.05; r=0.512), namun tidak terdapat hubungan yang signifikan antara tingkat kecukupan energi, protein, lemak, dan karbohidrat serta status gizi dengan tingkat kebugaran.

Judul: Hubungan Konsumsi Pangan dan Status Gizi dengan Tingkat Kebugaran Atlet Taekwondo Remaja di Pemusatan Latihan Nasional Cipayung, Bogor
Abstrak: The general objective of study was to analyze food consumption, adequacy ratio, nutritional status, and fitness level of adolescents taekwondo athletes in Centralization of National Training Cipayung, Bogor. The research used cross sectional study design with 23 adolescents athletes as samples. The primary data included characteristic of samples, nutritional status by anthropometry (body mass index), and food consumption. The secondary data included fitness level by bleep test (VO2 max values), sit and reach test (flexibility), sit up and squat jump (muscle endurance), and overview of the study site which was Centralization of National Training. The study showed that overall athletes has normal nutritional status. Most athletes were lack of sufficient levels of energy and protein. There was positive correlations between the ages of athletes with flexibility (p<0,05, r=0,456) and muscle endurance (sit up test) (p<0,05, r=0,456). The correlations between with fitness level (VO2 max) was positive significantly correlated (p<0,05, r=0,456).

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.
