Judul: The Relationship between Communication Network and Dissemination of Garden Tower Innovation in Women Farmer's Group
Abstrak: Jaringan komunikasi yang terbentuk di KWT dapat digunakan sebagai media dalam diseminasi terkait inovasi pertanian, salah satunya adalah Garden Tower yang dikembangkan oleh IPB dan USANA. Tujuan dari penelitian ini adalah untuk menganalisis jaringan komunikasi dan diseminasi Garden Tower serta hubungan di antara keduanya yang di KWT Melati dan Sekar Asri. Metode yang digunakan dalam penelitian ini adalah metode kuantitatif serta didukung oleh data kualitatif. Teknik pemilihan responden yang digunakan adalah teknik sampel jenuh. Hasil dari penelitian ini menunjukkan bahwa aktor yang sama menempati degree centrality, closeness centrality, dan betweenness centrality paling sentral dalam jaringan. Tingkat penilaian terhadap metode, model, dan strategi dalam diseminasi Garden Tower juga tergolong tinggi. Hasil uji korelasi menunjukkan adanya hubungan yang signifikan antara lama berusahatani dan lama keanggotaan dengan degree centrality, tingkat pendidikan dengan closeness centrality, dan tingkat pendidikan, lama berusahatani dan lama keanggotaan dengan betweenness centrality. Terdapat hubungan yang signifikan juga antara closeness centrality dan betweenness centrality dengan tingkat penilaian terhadap metode demonstrasi plot, model top-down, dan strategi fasilitatif., Communication networks formed in the Women Farmer’s Group can be used as a medium for disseminating related to agricultural innovation, one of it is the Garden Tower developed by IPB and the USANA. The aim of this research is to analyze the communication network and dissemination of Garden Tower as well as the relationship between them at KWT Melati and Sekar Asri. The method used in this research is a quantitative method and supported by qualitative data. The respondent selection technique used was a saturated sampling technique. The results of this research show that the same actors were in the most central of degree centrality, closeness centrality, and betweenness centrality in the network. The level of assessment of methods, models, and strategies in disseminating Garden Tower is also relatively high. The results of the correlation test show that there is a significant relationship between length of farming and length of membership with degree centrality, level of education with closeness centrality, and level of education, length of farming, and length of membership with betweenness centrality. There is also a significant relationship between closeness centrality and betweenness centrality with the level of assessment of plot demonstration methods, top-down models, and facilitative strategies.

Judul: Relationship between Group Dynamics and the Stages of acceptance of Garden Tower Innovation
Abstrak: Dinamika kelompok dapat membantu memfasilitasi tahap penerimaan inovasi yang menggunakan kelompok sebagai sasarannya karena di dalamnya melibatkan pengambilan keputusan bersama, seperti KWT Asri GWKP dan KWT Sawargi yang diberikan inovasi Garden Tower. Tujuan penelitian ini adalah untuk menganalisis hubungan dinamika kelompok dan tahap penerimaan inovasi Garden Tower pada KWT Asri GWKP dan KWT Sawargi. Penelitian ini menggunakan metode kuantitatif yang didukung oleh data kualitatif. Teknik pemilihan responden yang digunakan yakni teknik sampel jenuh. Hasil penelitian ini menunjukkan bahwa tingkat penilaian terhadap karakteristik inovasi seperti keuntungan relatif, kesesuaian, kompleksitas, kemungkinan dicoba dan kemudahan inovasi diamati tergolong cukup tinggi. Adapun dinamika kelompok pada kedua KWT tergolong tinggi. Hasil uji korelasi menunjukkan bahwa tidak ada hubungan antara karakteristik individu dan tahap pengetahuan pada penerimaan inovasi Garden Tower. Terdapat hubungan antara karakteristik inovasi dengan tahap persuasi. Terdapat hubungan yang signifikan antara dinamika kelompok dan kelima tahap penerimaan inovasi. Terdapat hubungan yang antar tahapan penerimaan inovasi Garden Tower., Group dynamics can help facilitate the adoption process of innovations that use groups as their target because it involves joint decision making, such as KWT Asri GWKP and KWT Sawargi who were given the Garden Tower innovation. The purpose of this study was to analyze the relationship between group dynamics and the adoption process of Garden Tower innovation in KWT Asri GWKP and KWT Sawargi. This research uses quantitative methods supported by qualitative data. The respondent selection technique used was saturated sample technique. The results of this study indicate that the level of assessment of innovation characteristics such as relative advantage, suitability, complexity, possibility of being tried and ease of innovation being observed is quite high. The group dynamics in both KWTs are high. The correlation test results showed that there was no relationship between individual characteristics and the knowledge stage of the Garden Tower innovation adoption process. There is a relationship between innovation characteristics and the persuasion stage. There is a significant relationship between group dynamics and all five stages of the innovation adoption process.

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.
