Introduction
Nowadays, the development of technology runs so fast and sophisticated. Everyone can get the up to date information through the use of internet quickly. It is a worldwide network that has fast speeds to help people to interact, connect and communicate with the others even from different countries. Moreover, the fourth industrial revolution stimulates the advanced technology in which internet is the smart tool to optimize the promotion of product (Liao, 2017, p. 1). It means that in this era, people are expected to face the globalization which is very competitive by optimizing their capacities by accessing internet to get the up to date information. Regarding the internet users in Indonesia, it shows that 2 million users and it has the fast growth as of June 2018 exceeded 100 million . Considering this, it proves that the majority of Indonesian people have already made use of digital information through the internet. Interestingly, they have accessed the internet for certain purposes such as to obtain the current information, promote something and so on.
In accordance with promotion, internet can be useful to promote local wisdom in a region or country in order the people around the world can know and hopefully after knowing the promotion of certain local wisdom, they want to visit it. Discussing about local wisdom, Indonesia has a number of local wisdoms that should be promoted in order foreign and local tourists can visit and enjoy the beauty of Indonesia in order to increase Indonesian devise. There is a local wisdom in Indonesia such as Raja Ampat in Papua, Mandeh Island in Padang, Kudus Minaret and Jenang Museum in Kudus, Central Java etc. By keeping the local wisdoms in Indonesia, it can create the harmony between man, nature and the built environment in an area that is also influenced by its culture (Dahliani, 2015, p. 157).
Unfortunately, there are some Indonesian local wisdoms that have not been promoted yet. Consequently, people do not know them because less promotion and they are nearly extinct such as the existed of Joglo house in Java, Padang house in Padang Kebaya house in Jakarta and, Panjang house in Kalimantan (Source: Liputan 6, 30 th August 2019). Indeed, they are rarely found in Indonesia nowadays. Ideally, Indonesia must be great country as big as USA because it has so many local wisdoms and it is a must for Indonesian to keep all of the local wisdoms in great ways. If the Indonesian do not do that, it will cause the other countries steal the ownership of them such as Batik case which claimed by the other country. Furthermore, Indonesian must filter annoyances from the other countries which are not suitable with the characteristics of Indonesia and give negative impacts to our beloved country especially in this disruption era that are very innovative, progressive and challenging to keep surviving (Santoso, 2018, p. 2). Therefore, as Indonesian, we must have the spirit of nationalism.
One of the ways to increase the spirit of nationalism is to keep the existence of local wisdoms in Indonesia is by using promotion through social media. Social media is online sharing tool to increase the communication of people around the world. They can communicate with other people in a fast way with or without face to face. There are many kinds of forms of social media such as Internet forums, you tube, weblogs, social blogs, micro blogging, wikis, podcasts (Baruah, 2012, p. 2). Social media has positive and negative impacts. One of the positive impacts of social media is the use of you tube to promote local wisdom.
A number of studies related to the use of social media have been undertaken by previous researchers. Video can be used as a media to create a project-based learning in learning speaking (Wahyuningsih, 2018, p. 82). Wahyuningsih & Dewi (2019, p. 2) have explored the use of YouTube Project in promoting English speaking proficiency in broadcasting among students in the department of Islamic Broadcasting and Communication at State Islamic Institute of Kudus. In addition, social media can be used as a meaningful media to create digitization of hadith in millennial era (Istianah & Wahyuningsih, 2019, p. 26). In term of entrepreneurship, social media especially Facebook has been used by women online entrepreneurs to promote their business (Mukolwe & Korir, 2016, p. 248). Likewise, social media can be considered as an effective tool to boost women entrepreneurship due to its flexibility (Melissa, Hamidati, & Hamidati, 2013, p. 77).
Unlike the previous studies exploring the social media for enhancing the qualified learning in educational and entrepreneurship settings, the present study highly focuses more on the use of investigating the use of social media particularly YouTube to promote local wisdom in Indonesia in accordance with the rapid development of technology in industrial revolution 4.0 era. In this sense, YouTube could be assumed as social media having positive roles in promoting something since the viewers can see the subject of the video, the object or place, the voice of the video and the colorful display picture in order the viewers are interested in accessing it. In addition, the YouTubers particularly the students in the department of Islamic Broadcasting and Communication at State Islamic Institute of Kudus can freely promote the Indonesian local wisdom so that it can be accessed by people around the world.
Surprisingly, the creator of YouTube can create the creative videos which are suitable with his or her own desire. Sometimes, to be creative, the creator can add with song or writing which are appropriate with the theme (Griffiths, 2017, p. 367). Hopefully, as the result of promotion, the Indonesian can keep the local wisdom in responding the industrial revolution 4.0 era. Thus, this study explores the role of social media in promoting the Indonesian Local Wisdoms especially in Central Java covering a number of cities such as Semarang, Demak, Kudus, Jepara and Pati.
