Judul: Kualitas Mikrobiologis Ayam Goreng Tepung yang Dijual di Dalam dan Sekitar Kampus IPB Dramaga Bogor Berdasarkan Jumlah Hitungan Cawan
Abstrak: Ayam goreng tepung merupakan makanan cepat saji yang banyak dijual dan dikonsumsi di Indonesia terutama mahasiswa. Penelitian ini bertujuan menghitung jumlah bakteri pada ayam goreng tepung yang dijual di kantin dalam dan sekitar Kampus IPB Dramaga Bogor. Sampel ayam goreng tepung dibeli dari 10 pedagang yang berada di dalam dan sekitar Kampus IPB Dramaga Bogor dalam radius sekitar 200 m dari batas luar lingkar Kampus dan setiap pedagang diambil 1 sampel dengan ulangan 3 kali. Ayam goreng tepung dibeli pada siang hari antara pukul 11.00 sampai 13.00. Ayam goreng tepung dibeli tanpa tambahan saus dan nasi. Sampel dimasukan ke dalam plastik steril kemudian dibawa dalam ice box yang berisi ice pack (suhu <7 oC) dan langsung diuji di laboratorium terhadap jumlah cemaran mikroorganisme berdasarkan metode SNI nomor 2897 Tahun 2008 tentang Metode Pengujian Cemaran Mikroba dalam Daging, Telur, dan Susu, serta Hasil Olahannya. Hasil penelitian diperoleh jumlah rata-rata mikroorganisme pada sampel ayam goreng tepung yang dijual di dalam dan sekitar Kampus IPB Dramaga Bogor yaitu 24 282.7+70 128.9 cfu/g. Dari penelitian ini dapat disimpulkan bahwa kualitas mikrobiologis ayam goreng tepung yang dijual di dalam dan sekitar Kampus IPB Dramaga umumnya baik untuk dikonsusmsi berdasarkan jumlah mikroorganisme. Jumlah mikroorganisme yang relatif tinggi pada ayam goreng tepung sebagai ready to eat food dapat memiliki resiko terjadinya penyakit bawaan pangan pada konsumen.

Judul: Total Microorganisms in Fried Chicken Sold Inside the Campus of IPB University Dramaga Bogor
Abstrak: The aim of this research was to observe the microbiological quality of fried chicken sold inside the campus of IPB University Dramaga Bogor based on the total plate counts. The samples were bought from 12 vendors which sold fried chicken inside the campus of IPB University Dramaga Bogor. In every vendor would be taken 1 sample with 3 repetitions and totally obtained 36 samples. The samples were taken between 1-2 pm and then delivered to the laboratory at Division of Veterinary Public Health and Epidemiology, Faculty of Veterinary Medicine, IPB University using coolbox with the temperature of 5-7 ºC. At the same day the samples were subjected to the examination of total plate counts using plate count method based on the method in SNI 2897:2008 regarding the Examination Method on Microbial Contamination in Meat, Eggs, and Milk and Their Products. The result showed that the average of total plate counts in the samples were 8 056.0 ± 17 215.0 cfu/g. All of the samples were below the maximum limit in the SNI 7388:2009 about Maximum Limit of Microbial Contamination on Foods (maximum limit 100 000 cfu/g). The microbiological quality of fried chicken based on total plate counts sold in the campus of IPB Dramaga Bogor was good. Key words: campus of IPB University Dramaga Bogor, fried chicken, total plate counts., Penelitian ini bertujuan untuk menentukan kualitas mikrobiologis daging ayam goreng yang dijual di dalam Kampus IPB Dramaga Bogor berdasarkan jumlah total mikrob. Sampel ayam goreng dibeli dari 12 kantin yang menjual ayam goreng di dalam Kampus IPB Dramaga Bogor. Setiap kantin diambil 1 sampel dengan ulangan 3 kali sehingga diperoleh 36 sampel. Sampel ayam goreng diambil pada pukul 13:00-14:30 WIB dan dibawa ke Laboratorium Divisi Kesehatan Masyarakat Veteriner dan Epidemiologi, Fakultas Kedokteran Hewan, Institut Pertanian Bogor menggunakan coolbox dengan suhu 5-7 ºC. Sampel ayam goreng diuji pada hari yang sama terhadap jumlah mikroorganisme atau total plate count (TPC) dengan metode hitungan cawan berdasarkan metode SNI 2897:2008 tentang Metode Pengujian Cemaran Mikrob dalam Daging, Telur, dan Susu, serta Hasil Olahannya. Hasil penelitian ini menunjukkan bahwa rata-rata jumlah total mikrob dalam ayam goreng adalah 8 056.0 ± 17 215.0 cfu/g. Seluruh sampel ayam goreng berada di bawah batas maksimum ketetapan SNI 7388:2009 tentang Batas Maksimum Cemaran Mikrob pada Pangan (batas maksimum sebesar 100 000 cfu/g). Kualitas mikrobiologi sampel ayam goreng berdasarkan jumlah total mikrob yang dijual di dalam Kampus IPB Dramaga Bogor tergolong baik.

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.
