Judul: Analisis permintaan konsumen rumah tangga terhadap telur ayam ras di Desa Margabakti Kecamatan Cibeureum dan Kelurahan Sukamulya Kecamatan Indihiang Tasikmalaya
Abstrak: Pertumbuhan ekonomi di segala sektor mengakibatkan meningkatnya pendapatan masyarakat, baik di kota maupun di pedasaan. Hal ini menunjukkan pengaruh nyata terhadap konsumsi pangan masyarakat, pada gilirannya akan mempengaruhi kemampuan untuk meningkatkan gizinya, terutama yang bersumber dari protein hewani yang relatif murah dan mudah di dapat sehingga yang berpendapatan menengah ke bawah lebih banyak mengkonsumsinya dibandingkan dengan daging sapi atau susu. Telur merupakan salah satu komoditas hewani yang berprotein tinggi serta murah dan mudah didapat, maka hal tersebut yang mendorong rumah tangga untuk mengkonsumsi telur. Tujuan penelitian ini adalah untuk menganalisis perilaku pembelian telur ayam ras konsumen rumah tangga, menganalisis faktor-faktor yang mempengaruhi jumlah permintaan konsumen rumah tangga terhadap telur ayam ras dan menganalisis elastisitas permintaan telur ayam ras di Desa Margabakti dan Kelurahan Sukamulya. ..

Judul: Permintaan rumah tangga konsumen terhadap telur ayam ras di Kecamatan Kandis, Kabupaten Siak, Riau
Abstrak: To day, egg is one of the primary consumption, because its price is relative low and as sources of protein. Prosperity of the people could be seen from the supply of nutrient. It is related with consumption and income. This research was held in Kandis Sub District, Siak District , Riau on September 1th 2th 2007. There were 60 housewives in Kandis Sub Diaict as respondents. The accidental sampling is used to pick the respondents. The result shows that cross elasticity of egg consumption was 17,8. There are three significant factors to egg consumptions in Kandis Sub District, they are price's egg of buras chicken, total of family member and taste. Total of egg consumption by holsehold consumer is 10,33 Kg/capita/year . The people in Kandis consume egg as protein source.

Judul: Characterizations of low alloy steel sae 4422  plated with chromic acid (Cro3)
Abstrak: Characterizations of low alloy steel SAE 4422 plated with chromic acid (CrOrO3) was use Optical Microscopy (OM), Scanning Electron Microscopy (SEM), X-Ray Diffraction (XRD), RD),Energy Dispersive Analysis of X-Ray (EDAX), Hardness Test and Roughness Test. Microstructures analysis exhibits cracks and grain boundaries microcracks as a characteristics of chrome metal found at plating metal. Perlite and Ferrite as grains of steel found at base metal with grain boundaries around it. Phase analysis of plating metal appropriate to chrome metal with lattice constant (a) is 2.559 Å and phase analysis of base metal appropriate to iron ferrite with lattice constant (a) is 3.318 Å. Both plating and base metal have cubic system. Chemical analysis of plating metal at surface section exhibits that cracks area have highest value of carbon element compare with grains and grains boundaries area. While chemical analysis of base metal at cross section exhibits that perlite have highest value of carbon element compare with ferrite and grain boundaries. The hardness value of plating metal at surface section and cross section are 753 and 637 VHN. While, the hardness value of base metal and interface area at cross section are 205 and 373 VHN. The roughness value at measurement points of chrome surface for as received sample are 0.445 μm. Observation used Optical Microscopy and Scanning Electron Microscopy exhibits surface irregularities combine to form surface texture of plating metal at surface section.
