Abstract

Ferroelectric materials of  Barium Strontium Titanate  (BST) with its  composition  of Ba0,3Sr0,7TiO3  was  succesfully deposited by a solid solution method. The samples were prepared in the form of pellets  and then  were annealed  at  the temperature of 600, 700, 800oC.   Characteritation of the samples was performed  using X-Ray diffraction (XRD). The results of characteritation using XRD was described on a graph  of the intensity  vs. 2 theta. The XRD  patterns of  Ba0,3Sr0,7TiO3  have  peaks. It was confirmed that the material of Ba0,3Sr0,7TiO3 has cubic crystalline structure, and its lattice parameter was  in average of 3,961 Å. The particle sizes (D) and lattice strains (η) of the material that was annealed at temperature of 600, 700, 800°C for 1 hour were 42.60, 44.43, 46.89 nm and -4,49x 10-3, -4,05 x 10-3,  -2,96 x 10-3, respectively. The increase in annealed temperature will raise the particle size and lattice strain.

Abstract

This study examines the legal responsibility of digital mobility platforms for merchant losses resulting from fictitious orders made by online transportation drivers, viewed from the perspective of consumer protection law. Using an empirical legal research method, the study combines normative analysis of laws such as the Consumer Protection Law and the ITE Law with field data obtained through interviews with the owner of the Burger Taqwa business. The findings reveal that fictitious orders often stem from weaknesses in the verification system and dishonest driver behavior. Although platforms like Gojek and Grab have implemented policies to delete fictitious orders and offer compensation, their enforcement is inconsistent and lacks transparency. Legal protections for merchants remain limited in practice, as the current regulatory and platform mechanisms prioritize end-consumers over business partners. The study highlights the need for stricter supervision, clearer legal accountability, and improved enforcement mechanisms to ensure fair protection for merchants in the digital economy ecosystem.

Abstract

The childfree phenomenon has become a hot topic in contemporary society. This choice not only reflects the dynamics of modern lifestyles but also raises legal, social, and religious controversies. This research aims to analyze childfree law from various perspectives, namely legal philosophy, Islamic family law, sociology, and anthropology, as well as career and population aspects. A multidisciplinary approach is used to understand this phenomenon in its entirety and comprehensively. From the perspective of Islamic law, child freedom is considered contrary to maqashid al-shariah, especially in safeguarding offspring (hifzh al-nasl), which is one of the purposes of marriage. However, from the perspective of legal philosophy, such decisions can be justified through the principles of personal autonomy and freedom of choice. Meanwhile, sociological and anthropological perspectives view childfree as a reflection of changes in social structure, individualistic values, and the influence of modern economics and lifestyle. In addition, career factors and population density also influence these preferences, which indirectly impact demographics and development. This study shows the importance of a balanced approach between religious norms, individual freedom, and social responsibility in responding to the childfree phenomenon in the modern era.
