Judul: Analisis pemilihan dan penempatan unit pembekuan untuk produksi daging sapi beku di DKI Jakarta
Abstrak: Pangan masih marupakan masalah yang penting khususnya dinegara barkembang seperti Indonesia. Hal ini disebabkan karena jumlah penduduk tidak seimbang dengan kenaikan produksi pangan, disamping tingkat kerusakan bahan pangan yang cukup tinggi sebelum dan sesudah panen.

Judul: Analisis usaha tani dan perhitungan harga pokok susu segar pada peternakan sapi perah rakyat  : (Studi kasus di Kelurahan Kuningan Timur, Kecamatan Setia Budi, Jakarta Selatan)
Abstrak: Usaha peternakan sapi perah di Indonesia telah ada sejak abad ke-19, yaitu dengan adanya impor sapi perah dari Australia, Kemudian pada awal abad ke-20 disusul dengan pengimporan sapi perah jenis "Fries Holland" (FH) dari Negeri Belanda. Pada tahun 1962 PN Perhewani mengimpor sapi perah FH dari Denmark guna mencukupi kebutuhan. susu pada pesta olah raga "Asian Games IV" di Jakarta. Kemudian pada tahun 1965 kembali diimpor sapi- sapi bibit FH dari Negeri Belanda oleh Jawatan Kehewanan. Pusat untuk meningkatkan produksi susu dalam negeri. DKI Jakarta merupakan salah satu daerah yang memiliki potensi cukup besar dalam usaha peternakan sapi perah. Permasalahan uBom yang dihadapi peternak dalam upaya pengembangan usaha peternakan sapi perah rakyat di DKI Jakarta khususnya di wilayah Kecamatan Setia Budi adalah sulitnya lahan untuk usaha peternakan, makin sulitnya ketersediaan hijauan ternak dan makin terdesaknya lahan usaha oleh adanya pembangunan/pengembangan wilayah serta adanya protes masyarakat terhadap dampak limbah usaha peternakan sapi perah. ...

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.
