Judul: Persentase Karkas dan Potongan Komersial Ayam IPB D1
Abstrak: Ayam kampung lebih unggul dari segi ketahanan terhadap penyakit, kondisi lingkungan yang kurang optimal, pemeliharaannya tidak membutuhkan persyaratan yang berat, namun memliki kekurangan seperti pertumbuhan lambat, produksi telur dan dagingnya rendah. Masalah ini dapat diselesaikan dengan persilangan antara ayam lokal (ayam pelung, sentul, dan kampung) dengan ayam ras pedaging yang menghasilkan ayam IPB-D1. Penelitian ini bertujuan untuk mengevaluasi persentase potongan komersial terhadap bobot potong ayam IPBD1 di Laboratorium Lapang Fakultas Peternakan Institut Pertanian Bogor pada umur 12 minggu. Bahan yang digunakan dalam penelitian ini adalah 15 ekor ayam IPB-D1 di Laboratorium Lapangan Fakultas Peternakan, Institut Pertanian Bogor pada umur 12 minggu. Data penelitian ini dianalisis secara deskriptif dengan menyajikan rata-rata (x̅) dan standar deviasi (sd). Persentase karkas D1- IPB di Laboratorium Lapangan Fakultas Peternakan, umur 12 minggu, jantan dan betina adalah 61.19% dan 60.86%. Ayam IPB-D1 memiliki nilai persentase dada dan jeroan yang tinggi, ini merupakan keunggulan ayam IPB-D1.

Judul: Persentase Bobot Karkas, Potongan Komersial dan Non Karkas Ayam IPB-D2 Generasi Keempat pada Umur 10 sampai 12 Minggu
Abstrak: Ayam lokal umumnya mudah dipelihara dan sistem ketahanan terhadap penyakit cukup baik serta adaptasi terhadap lingkungan cukup tinggi. Ayam IPB-D2 merupakan galur baru indukan (female line) yang dibentuk dari hasil seleksi ayam IPB–D1 berdasarkan sifat ketahanan penyakit yang baik dengan proporsi darah sama dengan ayam IPB–D1. Tujuan penelitian ini untuk mengkaji dan mengevaluasi persentase bobot karkas dan non-karkas, serta potongan komersial karkas dan non-karkas ayam IPB–D2 umur 10 hingga 12 minggu. Penelitian ini menggunakan ayam IPB-D2 Sukabumi sebagai data primer dan ayam IPB-D2 Boyolali sebagai data sekunder dengan jumlah ayam masingmasing 30 ekor. Jumlah ayam IPB-D2 G4 keseluruhan yang digunakan sebanyak 15 ekor. Hasil penelitian ini menunjukkan bahwa persentase karkas ayam IPBD2 Sukabumi lebih rendah dibandingkan Boyolali. Namun persentase bagian non karkas ayam IPB-D2 Sukabumi lebih tinggi dibandingkan Boyolali., Local chickens are generally easy to raise and have a fairly good system of disease resistance and high adaptation to the environment. IPB-D2 chickens are a new breed of broodstock (female line) which was formed from the selection of IPB-D1 chickens based on good disease resistance characteristics with the same blood proportion as IPB-D1 chickens. The aim of this research was to examine and evaluate the percentage of carcass and non-carcass weight, as well as commercial cuts of carcass and non-carcass IPB–D2 chickens aged 10 to 12 weeks. This research used IPB-D2 Sukabumi chickens as primary data and IPB-D2 Boyolali chickens as secondary data with 30 chickens each. The total number of IPB-D2 G4 chickens used was 15. The results of this research show that the percentage of IPB-D2 Sukabumi chicken carcasses is lower than Boyolali. However, the percentage of non-carcass portion of IPB-D2 Sukabumi chicken is higher than Boyolali.

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.
