Abstract

The role of young people in interfaith religious communities still faces challenges in character building and understanding in the field of dialogue. This situation arises from the impact of boredom, trauma, fear, stigma, and group divisions they experience. On the other hand, the lack of motivation among young people to engage in dialogue affects their participation, which often ends up as mere enjoyment without beneficial transformation. This study will examine an effort to foster an interest in dialogue among young people through YIPC (Young Interfaith Peacemaker Community). They have been involved in religious diversity issues since 2012, encouraging youth engagement in forms of dialogue: scriptural reasoning, interfaith dialogue, and social dialogue in an open, honest, and profound manner. They are also involved in a transformative process that promotes peace for religions, society, and the nation. This effort will be analysed using Paul F. Knitter's mutualism model. The mutualism model will serve as a basis for analysing YIPC’s dialogue efforts and exploring how understanding, collaboration, and transformation can be achieved in dialogue to create cooperation in addressing interfaith issues. This research will use a literature review method. This study provides relevance for understanding the YIPC process and its potential role in fostering an interest in dialogue among young people.

Abstract

Oryctes rhinoceros larvae are one of the sources of cellulose and hemicellulose degrading bacteria. Nutrition and energy sources together, with environmental factors have significant impacts on cellulolytic bacteria growth. Carboxymethyl Cellulose (CMC) media is a media often used to obtain cellulosic bacteria, while Nutrient Agar (NA) media is used for bacteria propagation. The use of NA for bacterial growth media is expensive. For the growth of O. rhinoceros symbiont cellulolytic bacteria, it is necessary to use alternative media that are cheap, easily available and contain sufficient nutrients to sustain bacterial growth. Soybeans, mackerel tuna, and jackfruit seeds contain high levels of protein and carbohydrate, which can be used as a nitrogen and carbon source for cellulolytic bacteria growth are easily available and cheap. This makes them excellent alternative for growth media materials. The aim of this research was to determine growth of symbiotic cellulolytic bacteria from O. rhinoceroson different alternative growth media. The research was conducted from January to May 2024 at the Plant Disease Laboratory, Faculty of Agriculture and Microbiology Laboratory, Faculty of Mathematics and Natural Sciences, University of Sumatera Utara. The experimental method used a factorial Completely Randomized Design (CRD) with 2 factors and 3 replications for each treatment combinations. The results showed that alternative growth media were suitable to sustain cellulolytic bacteria. The best treatment was mackerel tuna flour media with an average number of colonies of 100.5×106CFU/mL.
