The COVID-19 pandemic has disrupted many aspects of normal social life. The community is required not to leave the house too much if it is not necessary. Often during times of independent isolation or in personal cases, people are afraid to leave the house. They are faced with boredom so this is an opportunity for the digital entertainment industry to develop. On the other hand, many violations of COVID-19 health protocols still occur in society and people are still reluctant to stay-at-home. The question is what medium is good for persuasion as well as giving pleasure to people to entertain themselves during independent isolation and with low levels of boredom. Video games are a growing industry during the COVID-19 pandemic, unfortunately, this media has not been widely used as a means of persuading people to obey health protocols and stay-at-home. This study shows a correlation between gaming activity and the tendency not to leave the house. Besides, what types of games have the potential to keep someone from leaving the house are also discussed in this paper.

The potential for agricultural waste such as rice husks and corn cobs is very abundant and also can disturb the environment. However, this waste can be returned to agricultural land in the form of biochar or activated charcoal by means of pyrolysis using either low temperature or high temperature. Biochar is a byproduct of the thermochemical conversion of biomass which is recognized as a favorable soil amendment, which is introduced into the soil to increases groundwater retention in order to increases the saturated hydraulic conductivity of upper soil, affecting an aggregation, infiltration, and water capacity, decreasesing soil penetration resistance. Based on several previous studies, biochar can bind heavy metals contained in leachate, especially heavy metal Fe content. Utilization of leachate as an organic fertilizer which contains many nutrients essential for the growth of soybean plants. This research purposes to get the Fe-reduction influenced by biochar based on rice husk. The method used is to make biochar by pyrolysis process with low to high temperatures to obtain adsorption of heavy metals contained by leachate.

The COVID-19 pandemic has had a profound impact on the tourism industry since its emergence in late 2019. Visitor restrictions have led to a significant decline in activity across various sub-sectors of tourism, and prospective travelers have experienced burnout due to isolation. In such a situation, the digital industry has emerged as a rapid and interim solution. One intriguing digital technology that has garnered attention is Virtual Reality (VR). These efforts have been undertaken to ensure the sustainability of tourism destinations, and VR technology has piqued the interest of potential tourists. Despite its effective role in virtual promotion and learning, particularly for cultural heritage and archaeological sites like the Trowulan Site, stakeholders need to be supported through education on immersive technologies such as VR and their utilization in tourism and education, especially in the field of history. The adoption of VR technology in tourism destinations has experienced significant growth, but issues have arisen due to the lack of Human Resources (HR) related to VR Tourism content creation. As a result, the presentation of VR Tourism experiences has been delayed in terms of content updates, which can have a detrimental impact on the image of the tourism destination, potentially undermining its full potential. Awareness of this issue has been recognized by the Tourism Awareness Group (Pokdarwis) Ladewa, a stakeholder involved in the management of tourism destinations and travel packages in the Trowulan region. To address this issue, a proposed solution involves training related to VR Tourism and Social Media Content Creation as part of the digital marketing strategy for the tourism destination. This training will primarily focus on tourism themes with a sub-theme of enhancing the capacity of the Tourism Awareness Group (POKDARWIS) LADEWA.

In the last two decades, the Indonesian film ecosystem has been enlivened by the presence of local film festivals in various cities. The presence of film festivals is often seen as a space to channel interests, express creativity, build networks, and exchange knowledge and experiences. Local film festivals are generally initiated by student associations, film enthusiasts' communities, or government programs. Festival organizers also face various environmental challenges that are unstable in order to maintain their existence. It is not uncommon to find film festivals that have only been successfully held once or a few times, then postponed or discontinued for various reasons. Malang Film Festival (MAFI Fest) is the oldest local film festival initiated by a campus institution and has been able to survive from 2004 until now. This research aims to analyze the communication strategies used by the organizers to establish MAFI Fest as a sustainable local film festival, providing a space of appreciation for filmmakers to showcase their work. The research adopts a qualitative-descriptive approach, and data collection is conducted through interviews, observations, and documentation. The results of the research indicate that MAFI Fest implements repetitive, informative, and educative communication strategies through the media they use. The sustainability of the film festival is inseparable from the shrewdness of the organizers in innovating, support from stakeholders, their ability to obtain funding, and the commitment and activeness of its members. This research contributes to adding insight to academics and practitioners regarding the efforts that can be undertaken to maintain the sustainability of a local film festival in the long run.
