sub-indicators consisting of respect, empathy, being listened to or understood, openness, 
and humility possessed by communicators or extension workers.  
The results of this study are in line with  Rasyid, (2012) in extension activities for 
farmers carried out using a system of training and visits. The visit was carried out at the 
secretariat  of  the  group  and  gapoktan  or  rice  fields  owned  by  farmers  and  asked what 
problems were faced by farmers, but not all problems could be solved at the location. This 
system of exercises and visits is carried out three times a week. 
Sadono, (2009) as communication between people face-to-face, which allows each 
participant to capture the reactions of others directly, both verbally and nonverbally. Such 
communication indicates that the communicating parties are in close proximity, sending and 
receiving messages both verbal and nonverbal simultaneously and spontaneously. 
 
2. The Effect of Group Communication on the Adoption Rate of Postharvest Technology 
Innovation in Rice Rice Fields 
Indicators of group communication variables associated with the level of adoption of 
postharvest technology innovations are: (1) group discussion, and (2) group effectiveness. 
Nurdin et al., (2013) states group communication as face-to-face interaction between three 
or  more  people,  with  better  known  goals,  such  as  sharing  information,  taking  care  of 
themselves, problem solving, whose members can remember the personal characteristics of 
other members precisely. Group communication is a very important method of counseling 
because it produces opportunities to influence the behavior of its participants. 
The  results  of  statistical  calculations  show  that  the  communicator  regression 
coefficient of 0.510 with Sig at 0.038 shows a significant influence on the communicant 
variable.  This  result  proves  that  the  higher  group  communication  shown  from  group 
communication indicators, among others: (1) group discussion, (2) group effectiveness. In 
the group discussion indicator, there are sub-indicators consisting of increasing knowledge, 
changing attitudes and changing behavior, in the sub-indicators of increasing knowledge, 
group discussions can help members integrate knowledge by providing opportunities to ask 
questions, connect new information with what is already known. In the sub-indicators of 
attitude change, creating awareness of problems, problem formulation, changes in norms, 
and opinion formation. In sub-indicators of behavior change such as individual decision 
making,  collective  decision  making,  choice  making,  conformity,  social  facilitation  that 
shows smooth work quality, and polarization.  
In the group effectiveness indicator, there are sub-indicators of situational factors of 
group  characteristics  such  as group  size,  communication networks,  group cohesion and 
leadership, and group personal factors consisting of interpersonal needs, communication 
actions and roles. In this case the farmer says the members of the group work together to 
carry out the task of the group and maintain the morale of its members, besides that the 
purpose of the group is to share information with each other.  
This result is in line with the results of research conducted by Cahyanto & Sugihen, 
(2008)  which  revealed  that  group  communication  is  more  effective  than  other 
communications  because  farmers  are  guided  and  directed  in  groups  to  carry  out  more 
productive activities on the basis of cooperation. Group communication is more beneficial 
because it allows for feedback and group interaction that provides opportunities to exchange 
experiences and influence on its members. In this method, organizing in extension activities 
is directed at accelerating technology distribution at each level of the target of development. 
And B. Curtis, James J. Floyd, and Jerril L. Winsor  (2005) in (S. Suryanto & Safrizal, 
(2015) stated that group communication occurs when three or more people meet face-to-
