Abstract

Through tourism, especially cultural tourism, cultural dynamics turmoil also occurs in tourist destinations. This is because there is an inevitable tug-of-war between culture on the one hand and tourism on the other hand. Cultural traditions represent the expression of tradition and tourism represents modernity (economy). In general, cultural traditions have a tendency to preserve and tourism as the industry wants to maximize its business activities for profit. This research is more focused on the study of cultural practices which a focus on the discussion of Roland Barthes’s semiotics on the traditional art of jaranan. The results of this study can be concluded that Barthes’s semiotic analysis of the commodification of culture in jaranan art experiences a variety of forms and dance offerings that be conceptualized as profit-making. The concept of withdrawal is very clearly seen by the shift in religious magical meanings from sacred to profane in every performance.Keywords: Jaranan, Semiotics, Commodification of Culture

Abstract

Organic photovoltaic (OPV) devices have lower efficiency, shorter lifetimes, faster degradation, and poorer stability than inorganic photovoltaics (IPV) in ambient conditions. In this paper, the equivalent electrical circuit of a two-diode model effectively extracts the model-fit electrical photovoltaic (PV) parameters from degraded OPV devices, especially the series (Rs) and shunt (Rsh) resistances. The result shows a better correlation between the resistances of the devices and performance of the devices over the degradation process where the devices are deliberately exposed to ambient conditions under constant illumination. The degradation of the devices is mostly caused by the degradation of the aluminum (Al) electrode from water and oxygen, which correlates to the Rs. However, it is possible that the degradation of the bulk active layer can also occur due to the constant illumination on the device, which causes a reduction of photocurrent.

Abstract

The geographical location of Indonesia's territory is traversed by the Pacific Circum which makes many active mountain ranges in Indonesia. Reporting from National Geographic, as many as 90 percent of earthquakes originate from the Pacific Circum which are caused by volcanic activity. The frequent occurrence of natural disasters causes many losses in addition to losses such as damage to buildings, deaths and victims who suffer minor to serious injuries are victims who experience emotional problems such as depression, anxiety, excessive fear and worry, even PTSD. The existence of trauma healing volunteers for victims of natural disasters as mentioned above is really needed to prevent the psychological problems experienced by victims of natural disasters from becoming worse. The volunteers needed by victims are volunteers who are not selfish or prioritize their own interests, volunteers who have an empathetic attitude towards victims and are aware of people who need help. Such volunteers by Santrock are volunteers who have a prosocial attitude. This research aims to look at the prosocial picture which includes: cooperation, sharing, helping, honesty and generosity of trauma healing volunteers. This research is a qualitative research type of phenomenological study. Online interview techniques by calling each informant were used to explore data for this research. The research informants were 3 active Indonesian volunteers to date who have been volunteers for at least 3 years. The results of the research describe the prosocial nature of natural disaster volunteers based on prosocial aspects, which include: 1) cooperation: the cooperation of volunteers is shown by the volunteers' willingness to balance personal interests with the interests of the volunteer organization and also that the informants can respect other people who have provided opinions. 2) Sharing: the form of sharing shown by volunteers is that volunteers like to share their joys and sorrows with other people. 3) Helping: the forms of helping behavior shown by volunteers are Informal Planned Helping and Emotional Helping. 4) Acting honestly: The form of honesty shown by volunteers is being honest in their words, namely saying what they are and not cheating. 5) Generous: the informant's form of generosity is that volunteers like to give charity by donating the proceeds from holding webinars and raising funds online via kitabisa.com for victims of natural disasters

Abstract

Literary work is a profound expression of the soul of a writer to describe the existence of his identity. It is not uncommon for a person to express his creative ideas in literary verses as a symbol of the author to show that his condition is as stated in his work. Also included in the Serat Gatholoco, it is clear that the author is likely to experience one side of his life that is left out. By using imaginary characters he can show his identity. Serat Gatholoco deserves to be studied in scientific research, in this case, researchers use postcolonial studies with qualitative research types. While the primary data in this study are words, phrases, sentences, and paragraphs contained in Serat Gatholoco by Damar Shashangka. The results of this study concluded that the Serat Case of New, Java Literature is loaded with a charge of rebellion due to the arbitrary actions of the superordinate group to the others (liyan) which he considers subordinate. Serat Gatholoco is a reflection of the disgust of those who continually see rigidity in religious life. So those various strategies are used to reverse the binary opposition so that their existence is maintained.

Abstract

This study aims to find out how the role of the preacher in bringing changes to the social conditions of the people who used to work in the Dadapan prostitution localization, Kediri City. Da'i plays an important role as a propagator of religion to protect the community. Thus, the relationship between the preacher and his community must be close regardless of the background or social conditions of the community. This research uses a qualitative approach with a case study method and is equipped with George Homans' social exchange theory, namely as an analytical tool to understand and seek clarity of cases so that researchers know more clearly about the phenomenon of da'wah in the ex-Dadapan localization community. The results of this study conclude that the da'wah process that occurs in Dadapan Village in social exchange theory explains that they are willing to interact when the interaction produces benefits for themselves. Therefore, in the dynamics of increasing religious understanding in the ex-Dadapan localization, it is necessary to have a reward given so that people want to interact in discussing religious studies.
