Judul: Pengaruh Pemberian Booklet tentang Tatalaksana Beternak Sapi Perah pada Kegiatan Penyuluhan terhadap Peningkatan Pengetahuan Peternak
Abstrak: Some breeders didn’t have the knowledge and sufficient insight to understand their problems, think of the solution or to choose best solutions to achieve their goals. There was the possibility of their knowledge based on erroneous information because of lack of experience, education or other cultural factors. Therefore, it needed the counceling that was intended to eliminate barriers by providing information and provide insight into the problems faced. This study aimed to determine respondents' level of knowledge prior to the beginning of counseling and to see the effects of counseling intacked with the giving of booklet for increasing knowledge within the respondent. The design of this study was the control group of non-equivalence involved two groups, one experimental group and a control group. Experimental group was the group that had been influenced by variables (booklet). Whereas the control group was a group that was not affected by that variable. The results of this study: (1) respondents' level of knowledge prior to the beginning of counseling was homogeneous, (2) counseling by giving booklet didn’t give significant influence on improving knowledge of respondents about dairy breeding knowledge. Whereas counseling without booklet, it provides guidance which meant that the influence of increasing knowledge of respondents about dairy breeding knowledge. Based on research results obtained, then recommended that the implementation of face-to-face counseling activities should consider supporting the use of communication media, in this booklet. However, if will use communication media support (booklet) should be given after counseling. Keywords: booklet, experimental, knowledge of respondents

Judul: Pengaruh warna gambar booklet pakan sapi perah terhadap peningkatan pengetahuan peternak KUD giri tani di Desa Cibeureum Kecamatan Cisarua Kabupaten Bogor
Abstrak: Media komunikasi dalam bentuk booklet yang dirancang khusus untuk mendiseminasikan inovasi pakan sapi perah merupakan salah satu media komunikasi massa bergambar yang berguna bagi peternak. Penelitian tentang pengaruh warna perlu dilakukan agar pesan menjadi lebih menarik, mudah diingat dan mudah difahami Penelitian bertujuan untuk melihat adanya pengaruh penggunaan warna gambar pada booklet pakan sapi perah terhadap peningkatan pengetahuan peternak. Penelitian dilakukan di KUD Giri Tani Desa Cibeureum Kecamatan Cisarua, Bogor dari tanggal 17 Juni 8 Juli 1995. Penentuan sampel dilakukan dengan metode "purposive Sampling", yaitu dipilih peternak yang memiliki 4 sapi laktasi dengan jumlah peternak 30 orang. 7 ekor Data yang dikumpulkan terdiri dari data primer dan sekunder. Variabel bebas adalah isi booklet yaitu booklet berwarna dan booklet yang tidak diberi warna sedangkan variabel tidak bebas adalah peningkatan pengetahuan peternak tentang pakan sapi perah. Analisa data dilakukan dengan uji-t analisis sidik ragam satu arah. Hasil penelitian menunjukkan bahwa 86,7% peternak responden berjenis kelamin laki-laki, 56,7% berumur 38-63 tahun, 46,7% tidak lulus SD tapi semua peternak responden dapat membaca dan menulis, 80% peternak responden sudah beternak antara 5-10 tahun, 56, 7% mempunyai anggota keluarga 6-10 orang dan produksi susu sapi perah yang dimiliki rata- rata 11,899 liter. Hasil ujit menunjukkan terdapat perbedaan yang sangat nyata antara skor pre-test dan skor post- test (p < 0,01) yang berarti bahwa pengetahuan peternak meningkat setelah membaca booklet pakan sapi perah. Hasil analisis sidik ragam satu arah menunjukkan bahwa booklet berwarna sangat nyata meningkatkan pengetahuan peternak dibandingkan booklet yang tidak diberi warna (p < 0,01) yang berarti skor peningkatan peternak yang membaca booklet berwarna lebih tinggi dibandingkan skor peningkatan peternak yang membaca booklet yang tidak diberi warna.

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.
