Judul: Isolasi dan Identifikasi Bakteri Potensial Patogen pada Sampel Tanah Peternakan Kerbau (Sekolah Peternakan Rakyat) di Desa Tambang Ayam, Kecamatan Anyar, Kabupaten Serang
Abstrak: Banten merupakan salah satu provinsi yang memiliki jumlah populasi dan produksi ternak kerbau terbanyak di Indonesia. Peningkatan produktivitas ternak kerbau harus didukung dengan peternakan yang menunjang berbagai aktivitas ternak, terutama dari kondisi lingkungan. Penelitian ini bertujuan untuk mengembangkan sekolah peternakan rakyat melalui sektor kesehatan hewan dengan cara mengisolasi dan mengidentifikasi bakteri potensial patogen pada sampel tanah peternakan kerbau di Desa Tambang Ayam, Kecamatan Anyar, Kabupaten Serang yang dapat menimbulkan kerugian ekonomi bagi peternak rakyat. Sebanyak 11 sampel tanah diambil acak dengan metode komposit. Pengujian sampel dilakukan dengan menggunakan media API 20 E dan API 50 CHB untuk menentukan spesies bakteri. Data dianalisis secara deskriptif. Hasil penelitian menunjukkan bahwa spesies bakteri yang diperoleh terdiri dari 5 bakteri Gram negatif dan 4 bakteri Gram positif. Spesies bakteri tersebut adalah Pseudomonas fluorescens, Photobacterium damselae, Enterobacter cloacae, Pseudomonas aeruginosa, Vibrio parahaemolyticus sebagai bakteri Gram negatif. Sedangkan spesies bakteri Gram positif yang diperoleh adalah Bacillus cereus, Brevibacillus, Bacillus megaterium, dan Bacillus pumilus. Bakteri yang berhasil teridentifikasi berpotensial patogen dan dapat menimbulkan kerugian bagi ekonomi ternak adalah Bacillus cereus, Pseudomonas aeruginosa, dan Enterobacter cloacae.

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.
