Judul: Peranan komunikasi dalam meningkatkan partisipasi keluarga berencana masyarakat petani
Abstrak: Komunikasi merupakan proses yang penting dalam upaya merubah perilaku dan sikap seseorang terhadap stimuli tertentu. Upaya-upaya memasyarakatkan program Keluarga Berencana (KB), dimaksudkan agar pesan-pesan KB dapat dikenal, dimengerti dan diadopsi oleh masyarakat, tentu harus dikomunikasikan secara efektif sehingga masyarakat bersedia melaksanakan program KB yang dicanangkan oleh pemerintah ikut Progranm KB di Indonesia secara resmi oleh pemerintah sejak tahun 1968. Pada awalnya merupakan program pemerintah yang tidak mudah untuk dicanangkan program KB diterima oleh sebagian besar masyarakat Indonesia, tetapi dari waktu ke waktu menunjukkan keberhasilan yang patut dibanggakan oleh bangsa Indonesia. Hal ini terbukti Bapak Presiden Suharto pernah mendapat penghargaan dari badan Internasional (United Nation Population dari PBB pada tahun 1989) atas keberhasilan Indonesia di bidang kependudukan khususnya KB. Upaya menyadarkan masyarakat sampai berhasil demikian, tidak lain adalah melalui proses belajar mengajar masyarakat, mengetahui, mau memperhatikan, mau melakukan agar penilaian, mau mencoba dan pesan-pesan KB. akhirnya diharapkan mau menerima Salah satu metode mengajar masyarakat adalah dengan upaya-upaya mengkomunikasikan program tersebut dengan efektif sehingga masyarakat mau berpartisipasi (ikut serta) melaksanakan program-program KB. Kalau demikian halnya maka dapat dikatakan bahwa komunikasi berperan penting dalam upaya meningkatkan partisipasi KB masyarakat. Menyadari bahwa komunikasi mempunyai peran yang penting dalam menunjang keberhasilan KB, maka bertitik tolak dari pemikiran tersebut dilakukan penelitian ini untuk hui mengeta- peranan komunikasi dalam meningkatkan partisipasi KB masyarakat petani di desa-desa Kecamatan Wanareja, Kabupaten Cilacap. Lebih lanjut penelitian ini ingin mengetahui unsur-unsur komunikasi yang ikut berperan dalam menyampaikan pesan-pesan KB, yang meliputi: (1) Kemampuan komunikator, (2) Pentingnya isi pesan KB bagi komunikan, dan (3) Ketepatan penggunaan saluran /alat bantu komunikasi yang dipakai dalam me-nyampaikan pesan-pesan KB. ...

Judul: Faktor-faktor yang mempengaruhi efektivitas komunikasi di dalam sekolah lapang padi
Abstrak: A study was carried out to analyze the relationships among influencing factors to communication effectiveness in socialization of technological innovation in conducting the program of Field School of Integrated Crop Management of Rice, in Cikarawang Village, Bogor Barat Sub-district, Bogor City. Data were collected using questionnaire method, and then analyzed using τ - Kendal descriptive method. The results of the study showed that the factor of field guide characteristic had a significant correlation with the communication participation of farmer. The field guide characteristics also had a significant correlation with the technological innovation characteristic (i.e. trialibility and observability). Some elements of farmer characteristics (i.e. age and experience) significantly correlated with the communication participation of farmer. However, all elements of communication channels (type of media and place and time suitability) were not correlated with the communication participation of farmer. This could be due to the absence of other type of media, other than the direct communication (meeting, discussion and field practice). Farmer participation to the main activities of the field school program (PRA, meeting, discussion and field practice) significantly correlated with the knowledge enhancement (cognitive) and with the attitude change tendency (affective) of program-involved farmers. However, the communication participation of farmer was not correlated with the action of program-involved farmers to apply technological innovation of the field school. In other words, although program-involved farmers had obtained enough knowledge and had tendency to choose technological components in the field school program, but in general they had not yet applied optimally the components.

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.
