Judul: The Analysis of Food Consumption in West Java Province
Abstrak: Tujuan penelitian ini adalah menganalisis ketersediaan pangan; karakteristik sosiodemografi; karakteristik ekonomi; dan situasi konsumsi pangan; serta hubungan antara ketersediaan pangan, karakteristik sosiodemografi, dan karakteristik ekonomi dengan konsumsi pangan penduduk Provinsi Jawa Barat. Tidak terdapat kabupaten/kota yang mencapai skor PPH ketersediaan pangan ideal sebesa 100. Beberapa wilayah termasuk padat penduduk seperti Kota Bogor, Kota Bandung, Kota Bekasi, dan Kota Depok. Rata-rata lama sekolah di kabupaten/kota belum ada yang memenuhi program pemerintah wajib belajar 12 tahun. Pengeluaran pangan penduduk, tingkat kemiskinan serta harga pangan di setiap kabupaten/kota tidak merata. 17 kabupaten/kota termasuk TKE cukup dan 10 kabupaten/kota termasuk TKE lebih. 10 kabupaten/kota termasuk TKP cukup dan 17 kabupaten/kota termasuk TKP lebih. Tidak ada kabupaten/kota yang mencapai skor PPH 100. Uji korelasi menunjukkan bahwa terdapat hubungan searah antara TKE ketersediaan(p<0,01) dan tingkat kemiskinan (p<0,05) dengan TKE konsumsi. Terdapat hubungan tidak searah antara rata-rata lama sekolah (p<0,01) dan harga minyak (p<0,01)dengan TKE konsumsi. Terdapat hubungan searah antara pengeluaran pangan (p<0,05) dengan skor PPH konsumsi. Tidak terdapat hubungan antara ketersediaan pangan, jumlah penduduk, rata-rata lama sekolah, pengeluaran pangan perkapita, harga pangan dan tingkat kemiskinan dengan TKP konsumsi.

Judul: Situation Analysis of Food Consumption, Stunting, and  Life Expectancy in West Java Province
Abstrak: Penelitian ini bertujuan menganalisis situasi konsumsi pangan, stunting, dan Angka Harapan Hidup (AHH) kabupaten/kota di Provinsi Jawa Barat tahun 2015 sampai 2018. Data yang digunakan yaitu data sekunder dengan unit analisis 27 kabupaten/kota di Provinsi Jawa Barat tahun 2015 sampai 2018. Hasil penelitian menunjukkan di Provinsi Jawa Barat terjadi peningkatan jumlah penduduk, AHH, dan skor pola pangan harapan (PPH); penurunan laju pertumbuhan penduduk dan tingkat kemiskinan; serta fluktuasi tingkat kecukupan energi (TKE), tingkat kecukupan protein (TKP), dan prevalensi stunting. Selama empat tahun (2015– 2018), terdapat 71 (65,7%) kabupaten/kota dengan TKE baik dan 37 (34,3%) kabupaten/kota dengan TKE sedang, serta terdapat 97 (89,8%) kabupaten/kota dengan TKP baik dan 11 (10,2%) kabupaten/kota dengan TKP sedang. Jumlah kabupaten/kota dengan masalah stunting yang tinggi dan sangat tinggi meningkat setiap tahun dari tahun 2015 sampai 2018. Uji korelasi berganda menunjukkan terdapat hubungan terikat yang kuat (r=0,750) antara jumlah penduduk, LPP, tingkat kemiskinan, TKE, TKP, skor PPH, dan prevalensi stunting secara simultan dengan AHH., This research aims to analyze the situation of food consumption, stunting, and life expectancy in regencies/cities of West Java Province 2015–2018. Data that used was secondary data with units of analysis were 27 regencies/cities in West Java Province in 2015 to 2018. The result showed that in West Java Province, the population, life expectancy, and Desirable Dietary Pattern (DDP) score have increase; population growth rate and poverty rate have decrease; and energy adequacy levels, protein adequacy levels, and stunting prevalence have fluctuated. Within four years (2015–2018), there are 71 (65,7%) regencies/cities with good energy adequacy level and 37 (34,3%) regencies/cities with moderate energy adequacy level, there are 97 (89,8%) regencies/cities with good protein adequacy level and 11 (10,2%) with moderate protein adequacy level as well. The number of regencies/cities with high and very high stunting categories are increasing every year from 2015 until 2018. The multiple correlation test showed there was a strong correlation (r=0,750) between population, population growth rate, poverty level, energy adequacy level, protein adequacy level, DDP score, and stunting prevalence simultaneously with life expectancy.

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.
