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 The Situation and Determinant Factors  Affecting Food Consumption among Population in DKI Jakarta Province
Abstrak: Penelitian ini bertujuan untuk untuk menganalisis situasi konsumsi pangan penduduk serta faktor determinan wilayah terkait di Provinsi DKI Jakarta. Penelitian ini menggunakan data sekunder dari BPS dan Badan Ketahanan Pangan yang diolah dan dianalisis secara kuantitatif dengan teknik deskriptif. Hasil penelitian ini menunjukkan bahwa rata-rata peningkatan jumlah penduduk sebesar 84.591 jiwa tiap tahunnya. Rata-rata peningkatan RLS sebesar 0,09 tahun dan rata rata peningkatan pengeluaran pangan sebesar Rp 52.267/kap/bulan tiap tahunnya. Rata-rata persentase pengeluaran pangan sebesar 38,65%. Tingkat kecukupan energi (TKE) di Provinsi DKI Jakarta tahun 2013-2020 terendah sebesar 86,2% dan tertinggi sebesar 106,2%. Tingkat kecukupan protein (TKP) terendah sebesar 102,1% dan tertinggi sebesar 126,8%. Skor PPH belum ada yang mencapai skor PPH maksimal tetapi sudah tergolong cukup baik yaitu terendah sebesar 81,7 dan tertinggi sebesar 89. Forecasting jumlah penduduk tahun 2021-2023 menggunakan metode deret geometri. Forecasting RLS, pengeluaran pangan, TKE, TKP, dan skor PPH menggunakan metode moving average. Hasil uji regresi menunjukkan bahwa jumlah penduduk dan pengeluaran pangan tidak berpengaruh secara signifikan terhadap TKE, TKP, dan skor PPH konsumsi pangan (p>0,01). RLS berpengaruh secara signifikan terhadap TKE (p=0,0948) dan skor PPH (p=0,0775), tetapi tidak berpengaruh secara signifikan terhadap kuantitas TKP konsumsi pangan (p>0,01)., This research aims to analyze the population's food consumption situation and related regional determinant factors in DKI Jakarta Province. A secondary data from BPS and Food Security Agency which was processed and analyzed quantitatively using descriptive techniques. The results of this research showed that the average population increase is 84591 people each year. The average increase in RLS is 0.09 years and the average increase in food expenditure is IDR 52267,00/cap/month each year. The energy adequacy level (TKE) was the lowest at 86.2% and the highest at 106.2%. The lowest level of protein adequacy (TKP) was 102.1% and the highest was 126.8%. No PPH score has yet reached the maximum PPH score but it is quite good, the lowest is 81.7 and the highest is 89. Forecasting total population in 2021-2023 uses the geometric series method. Forecasting RLS, food expenditure, TKE, TKP, and PPH scores using the moving average method. The results of the regression test showed that total population and food expenditure did not significantly affect TKE, TKP, and PPH score of food consumption (p>0.01). RLS did significantly affect TKE (p=0.0948) and PPH score (p=0.0775), but did not significantly affect TKP food consumption (p>0.01).

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.
