Interpersonal Communication
Communication is derived from Latin word "communicare" that means "to share" or "to make common" (Coates, 2009). In this context, sharing or making common means to share information or message that could be received by other people. Communication is the process of conveying message or information from one to another (Keyton, 2011). Communication happens when it fulfills some elements (Cheney, 2011) as depicted in Fig. 1. The use of media in communication tends to be disturbed, such as network interference when using internet. From the statements above, communication can be defined as a process of conveying message done by two or more people, involving message sender and message receiver and subsequently induce a feedback.
Interpersonal communication is a communication that usually done by two individuals. Interpersonal communication is usually based on an intimacy of formality to someone (McLean and Moman, 2012). Other argument states that interpersonal communication is a communication that involved two to three people (Wood, 2014).
From those definitions, it can be concluded that interpersonal communication is a process of conveying message done by two people involving message sender and message receiver that induce feedbacks from those people.

Blackberry Messenger and WhatsApp
Blackberry Messenger is an application provided in Playstore that can be usedto chatby text, voice call, or video call. Blackberry Messenger can also be used to share photo, send a location, broadcasting, multi personal chatting, and group chatting.

WhatsApp is a chat application as well as Blackberry Messenger that runs by the presence of internet connection (4G/LTE, 3G, 2G, Edge, or Wifi).

WhatsApp can be installed in numerous Smart phones like Android, iPhone, Windows Phone, and some types of Nokia phone. WhatsApp can also be used to send text messages, phone calls, video calls, making group, and send various files such as images, videos, recordings, music, and locations.

Research Method
This research used qualitative research method with some samples to strengthen the research results. A qualitative research is done by constructing reality and understanding its meaning (Somantri, 2005). Qualitative research method was chosen because of the limitation of research, incomplete data, or insufficient research variables (Yin, 2011). Qualitative research originated from the depth, nuance, context, multidiscipline, and complexity. The result of qualitative research could be derived from valid findings through comparison and conclusion (Kumar, 2011). This research used media richness theory, which states that through communication channel a conveyed message has high noise level so that by this theory the message can be conveyed perfectly (Daft and Lengel, 1984).

Result and Discussion
Through media richness theory, this research results showed that emoji and emoticon have a very important role in interpersonal communication. In media richness theory, Blackberry Messenger and WhatsApp fulfill the criteria of: 1) Ability of communication channel in conveying message signals such as facial expression, body movement, and vocal inflection; 2) Feedbacks are directly given by the message receiver as response to every chats, 3) Variety of language such as the presence of symbols and foreign language, and 4) Ability of communication channel in conveying personality such as showing personal emotion (Daft and Lengel, 1984).
Through chat trials with a number of WhatsApp users, the use of emoji in WhatsApp can be shown on Fig. 2. Through three different chats shown in Figure 2, it can be concluded that emoji or emoticons are indeed can be used to strengthen the message content. By using emoji, the message sender can express emotions through pictures available on their Smart phones. Angry, sad, happy, disappointed, shocked, or any other emotions can be expressed in form of a picture. But the expression of emotion through emoji is not always correct. For example, an angry girl will not always use angry emoji to express her feeling. She can use other emoji to cover the real feeling so that the message receiver wouldn't be guilty.
Emoji and emoticon can strengthen the meaning of sent message so that the receiver will feel the emotion of message sender. In message delivery, an emoticon can make the difference. With an emoji or emoticon, a message can have more extreme emotion (Ip, 2002). An emoji can also help to express thoughts and feelings by using digital media with universally known facial expression (Mesquita et al., 1997). Emoji or emoticon should be used in suitable message so that the message can have stronger emotion and represent the sender's emotion (Stark and Crawford, 2015). Emoticon is an icon with facial emotion shape which is usually used in text message to represent emotion and personality in interpersonal communication (Dunlap et al., 2016). By the use of emoji, the emotion of message receiver will be triggered more strongly, and furthermore understanding the message meaning (Luminet et al., 2000).

Emoticon is frequently used in positive messages such as thankfulness, compliment, regards, etc (Brown and Levinson, 1987)  Some examples above show that emoticon can strengthen the positive text message. The usage of negatively oriented emoticon is rarely seen because an angry person tends to bother making an emoticon with his present emotion.

According to media richness theory, there are four factors that determine good delivery of message: 1) Ability of communication channel in conveying message signals such as facial expression, body movement, and vocal inflection; 2) Feedbacks are directly given by the message receiver as response to every chats, 3) Variety of language such as the presence of symbols and foreign language, and 4) Ability of communication channel in conveying personality such as showing personal emotion (Daft and Lengel, 1984). In interpersonal communication, the usage of nonverbal symbols such as facial expression and body movement could make the message clearer (Cui et al., 2017). Responded nonverbal symbols will support feedback in form of other emotion. The essence of media richness theory is language and symbol (Littlejohn, 1983). Clear language and supporting symbol will make interpersonal communication in a media runs well as expected.

In interpersonal communication, emoticon's role is increasing the connection with other person in chat, showing emotion expression, and as a strategy to show present condition (Maíz-Arévalo, 2015). Brain is 60000 fold faster in responding pictures than ordinary text, so a picture is an important element in interpersonal communication (Jibril and Abdullah, 2013).
From the research result, it could be known that emoji and emoticon is highly needed in interpersonal communication through digital technology. The role of emoji and emoticon is to support the message meaning. The usage of emoji or emoticon should match with the message. For example, a warning message should use angry emoji or emoticon instead of happy ones.
