Abstract

Perovskite materials, including barium titanate (BaTiO3), are important ferroelectric materials in industry and research today. Ferroelectrics have unique properties such as piezoelectricity, high permittivity, and electrocaloric and electrooptic effects that are beneficial in technological applications. BaTiO3, for example, is a lead-free ferroelectric material relevant for FeRAM and ferroelectric tunnel junctions. However, research on BaTiO3 flexible thin films is still limited, especially in the context of flexible substrates. Therefore, research in the preparation of stable and flexible BTO ferroelectric films is crucial for the advancement of nonvolatile memory devices. The manufacturing method in this study is the Sol Gel Method where the relative molecular mass of BaCO3 material is calculated, then the mass value is entered with the composition of (X)BaTiO3-(1-X)BaZr0.5Ti0.503. After the test is performed using mangosteen leaves, the resulting wave peaks from the FTIR Spectroscopy analysis can be seen. This is one of the characterization methods used to analyze the molecular structure and functional groups of various materials from which samples are made. This analysis indicates that mangosteen leaves contain various organic compounds, including alcohols, alkanes, and carbonyl compounds. In this research, further development is needed so that improvements can be made in the synthesis of ferroelectric material BaTiO3 used as a stabilizing agent.

Abstract

Motivasi individu merupakan hal yang mendorong seseorang untuk bertindak. Motivasi masyarakat desa bergabung dengan BUMDES Trimulya Mandiri Desa Pematang Manggis Kecamatan Batang Cenaku Kabupaten Indragiri Hulu mempunyai berbagai alasan baik yang bersifat internal maupun eksternal. Tujuan dari penelitian ini adalah untuk mengidentifikasi faktor pendorong yang melatarbelakangi keputusan Masyarakat Desa Pematang Manggis untuk bergabung dengan BUMDES Trimulya Mandiri. Pendekatan pada penelitian ini yaitu penelitian deskriptif kualitatif lapangan (field research). Teknik pengumpulan data beruapa wawancara, observasi dan dokumentasi. Teknik sampel penelitian dengan teknik purposive sampling. Key informan yaitu Kepala Desa, Sekretaris Desa, Direktur BUMDES, Kepala Dusun serta Masyarakat setempat. Analisis data pada penelitian ini berupa triangulasi, redaksi data, penyajian data dan penarikan kesimpulan.  Hasil penelitian menyimpulkan bahwa faktor-faktor yang menjadi ketertarikan masyarakat bergabung dengan BUMDES seperti kemudahan sistem, lokasi yang dekat, keamanan dalam menabung, serta manfaat ekonomi dan sosial menjadi motivasi utama bagi anggota untuk bergabung. Dengan semakin banyaknya partisipasi masyarakat, BUMDES Trimulya Mandiri diharapkan dapat terus berkembang dan memberikan kontribusi nyata dalam meningkatkan kesejahteraan desa.

Abstract

This study aims to understand the perspective of the Regional Disaster Management Agency (BPBD) of Medan City in interpreting the concept of disaster, as well as how this understanding influences the implementation of duties and cross-agency coordination. The research method used is a descriptive qualitative approach through in-depth interviews with BPBD Medan City officials and documentation studies of relevant policies and legislation. The results of the study indicate that BPBD Medan City possesses a conceptual understanding consistent with Law Number 24 of 2007 on Disaster Management; however, there remains a gap in understanding at the community level. BPBD serves as the main command, coordinator, and executor of disaster management efforts and forms integrated teams according to the type of disaster occurring. Nevertheless, the low level of community literacy regarding the meaning of disasters often leads to misconceptions about BPBD’s responsibilities.
