Malang City has evolved into a prominent hub for students. Embracing this new role, it has become a sought-after destination for learners from outside Java who wish to pursue their education at local universities. The influx of international students brings a vibrant intercultural dynamic to the city, affecting both the local community and the students themselves. As these students undergo the adaptation process to integrate and thrive in their new environment, they often face challenges such as culture shock, which arises from insufficient preparation and knowledge about their new surroundings. Culture shock can be minimized in the process of student adaptation by the application of intercultural communication, which can bridge the constraints of understanding in society. This research aims to examine the impact of intercultural communication on the adaptation process of Hindu students in Malang City, focusing on how it can reduce the incidence of culture shock. Employing a qualitative-interpretative approach, the research gathers data through comprehensive and interactive interviews based on the informants' personal experiences. Informants are selected using purposive sampling, and data is analyzed using the Miles and Huberman framework, which involves data collection, reduction, and interpretation. The outcomes highlight that culture shock among Hindu students in Malang City is influenced by internal factors, including personal abilities, insufficient factual information, and experiences in intercultural social interactions. While external factors include language, food, customs, and climate. The phases of culture shock development in the adaptation process include the optimistic phase, cultural phase, recovery phase, and adjustment phase. The duration for students to transition from experiencing culture shock to achieving adaptation ranges from one month to a year. Effective intercultural communication plays a crucial role in this adaptation process, helping to reduce the impact of culture shock by facilitating stages of convergence, divergence, and maintenance.

Manipulation of inorganic materials with organic macromolecules enables organisms to create biominerals such as bones and seashells, where occlusion of biomacromolecules within individual crystals generates superior mechanical properties. Current understanding of this process largely comes from studying the entrapment of micron-size particles in cooling melts. Here, by investigating micelle incorporation in calcite with atomic force microscopy and micromechanical simulations, we show that different mechanisms govern nanoscale occlusion. By simultaneously visualizing the micelles and propagating step edges, we demonstrate that the micelles experience significant compression during occlusion, which is accompanied by cavity formation. This generates local lattice strain, leading to enhanced mechanical properties. These results give new insight into the formation of occlusions in natural and synthetic crystals, and will facilitate the synthesis of multifunctional nanocomposite crystals.
