Judul: Access and Consumption of Population Food and Its Relationship with the Prevalence of Obesity in the Adult Population in Indonesia in 2018
Abstrak: Prevalensi obesitas penduduk usia dewasa di Indonesia terus mengalami peningkatan.Obesitas dapat meningkatkan risiko penyakit tidak menular yang dapat menyebabkan penurunan kualitas hidup dan kematian.Tujuan penelitian ini adalah mengetahui hubungan antara akses pangan dan konsumsi pangan penduduk dengan prevalensi obesitas penduduk usia dewasa per provinsi di Indonesia tahun 2018. Variabel yang diteliti yakni pendapatan per kapita, Rata Lama Sekolah (RLS), Indeks Harga Konsumen (IHK), TKE, TKP, skor PPH, dan prevalensi obesitas penduduk usia dewasa. Desain penelitian adalah crossectional study dengan pendekatan ecology study yang menggunakan data sekunder berasal dari data Provinsi Dalam Angka 2019, Direktori Perkembangan Konsumsi Pangan Penduduk Indonesia 2019, dan Riskesdas 2018 Dalam Angka. Hasil uji korelasi moment pearson menunjukkan ada hubungan positif antara rata-rata pendapatan per kapita dan RLS penduduk dengan prevalensi obesitas penduduk usia dewasa. Tidak ada hubungan antara IHK dengan prevalensi obesitas penduduk usia dewasa. Tidak ada hubungan antara TKE, TKP, dan skor PPH konsumsi pangan penduduk dengan prevalensi obesitas penduduk usia dewasa per provinsi di Indonesia tahun 2018.

Judul: Analysis of Socio-economic Factors Associated with  Animal-based Food Consumption in Indonesia
Abstrak: Konsumsi pangan hewani dalam jumlah cukup dinilai penting untuk membantu mencegah terjadinya masalah gizi termasuk stunting. Faktor sosial ekonomi menjadi salah satu faktor yang dapat mempengaruhi konsumsi pangan hewani penduduk. Penelitian ini bertujuan untuk menganalisis hubungan antara berbagai faktor sosial ekonomi terhadap konsumsi pangan hewani di Indonesia. Desain penelitian ini adalah cross sectional menggunakan data sekunder dari 34 provinsi di Indonesia yang mencakup data jumlah penduduk, rata-rata lama sekolah, PDRB per kapita, pendapatan riil, tingkat kemiskinan, tingkat pengangguran, dan konsumsi pangan hewani. Penelitian dilakukan pada bulan April-September 2021. Hasil analisis regresi linear berganda menunjukkan bahwa PDRB per kapita dan tingkat pengangguran memiliki hubungan positif (p<0,05), sedangkan jumlah penduduk dan tingkat kemiskinan berhubungan negatif dengan konsumsi pangan hewani (p<0,05). Upaya untuk mengontrol jumlah yang bertujuan untuk mengurangi tingkat kemiskinan dan pengangguran, serta stabilitas ekonomi diperlukan untuk meningkatkan GDRP yang selanjutnya menjamin pemenuhan konsumsi pangan., To avoid nutrition disorders, including as stunting, adequate animal-based food consumption is required. Various socioeconomic factors may influence the community's intake of animal-based foods. The goal of this study was to look at the socioeconomic aspects that influence animal-based food intake in Indonesia. The study was cross-sectional and included secondary data from 34 Indonesian provinces, including information on population, mean school years, GDRP per capita, real income per capita, poverty level, unemployment rate, and animal-based food consumption. The research took place from April to September of 2021. Multiple linear regression analysis revealed significant positive relationships between GRDP per capita and unemployment rate and animal-based food consumption (p<0.05), but substantial negative relationships between population and poverty rates and animal-based food consumption (p<0.05). To increase GRDP and assure food consumption, population restrictions aimed at lowering poverty and unemployment rates, as well as macroenonomic stability, are required.

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.
