Abstract

Salah satu pengaruh dari berkembangnya teknologi dan ilmu pengetahuan adalah munculnya bidang kimia baru yaitu kimia komputasi. Kimia komputasi adalah penggabungan antara unsur eksperimental dengan teori dalam suatu sistem kimia menggunakan perangkat komputer. Pada penelitian ini, digunakan software Hyperchem 8.0 (windows) dengan metode semi-empiris PM3 untuk menghitung celah energi senyawa kompleks bis(benzoiltrifluoroaseton)zirkonium (bis(btfa)2Zr). Selain itu, dilakukan juga analisis spektrum ultraviolet (UV) pada senyawa kompleks tersebut untuk menentukan panjang gelombang maksimumnya. Berdasarkan hasil perhitungan, diperoleh celah energi ligan btfa lebih besar dibandingkan senyawa kompleks bis(btfa)2Zr. Sebaliknya, berdasarkan analisis UV diperoleh panjang gelombang maksimum kompleks bis(btfa)2Zr lebih panjang dibandingkan ligan btfa. Hasil data ini menunjukkan bahwa celah energi senyawa kompleks bis(btfa)2Zr berbanding terbalik dengan panjang gelombang maksimumnya.

Abstract

The authority of the Constitutional Court is a separate study in this article. The authority of the Constitutional Court in accordance with the provisions of Article 24C Paragraphs (1) and (2) is to adjudicate at the first and final level to test laws against the Constitution, decide disputes over the authority of state institutions whose authority is granted by the Constitution, decide on the dissolution of political parties and decide disputes regarding the results of general elections. . Apart from that, the Constitutional Court can also give decisions to the DPR if they commit violations and also the President and Vice President who are submitted to the Constitutional Court

Abstract

Kemajuan teknologi memberi dampak pada berbagai hal. Salah satu dampak kemajuan teknologi adalah munculnya inovasi baru dalam bidang kimia, yaitu kimia komputasi yang mengolaborasikan komponen dari konsep-konsep kimia dan eksperimen dengan bantuan perangkat komputer. Pada riset ini, software yang digunakan adalah Hyperchem 8.0. Metode yang digunakan adalah semi-empiris PM3. Penelitian ini bertujuan untuk menghitung nilai celah energi dan panjang gelombang maksimum dari ligan dibenzoilmetana dan senyawa kompleks bis(dibenzoilmetanato) zirkonium. Berdasarkan hasil perhitungan, diperoleh celah energi ligan lebih besarĀ  dibandingkan celah energi senyawa kompleks. Selanjutnya, panjang gelombang maksimum ligan lebih kecil dibandingkan panjang gelombang maksimum senyawa kompleks. Hasil yang diperoleh ini telah sesuai dengan teori, yaitu persamaan energi foton yang menyatakan bahwa energi berbanding terbalik dengan panjang gelombang maksimum.

Abstract

This research discusses the effect of the storytelling method conducted by Sunday School teachers on the understanding of the Bible in children aged 3-6 years. The decline of attitude in early childhood is a cause for concern. This decline in attitude is caused by one of the problems, namely the lack of understanding of the Bible. The lack of teaching the Bible to children from an early age is a matter of concern. The storytelling method is a learning approach that prioritizes narratives or stories as the main medium in the religious learning process. Through interesting and interactive narratives, this method aims to increase children's understanding, engagement, creativity, and cognition, as well as forming positive attitudes towards religion and transferring moral values. This research uses a descriptive qualitative approach by collecting data from various literature sources related to the research topic. Data analysis was conducted systematically using a qualitative approach to generate new insights that can increase understanding of existing knowledge. The results showed that the storytelling method had a significant impact in several aspects. Firstly, it increases children's engagement in religious learning, allowing them to be actively involved and building a strong interest in the Bible. Second, it influences the growth of children's positive attitude towards religion, positively shaping their character and morality. Third, the storytelling method facilitates a deeper understanding of the Bible, allowing children to internalize the spiritual and moral values contained in the Bible stories. Fourth, it helps in the development of children's language and cognitive skills, enriching their learning experience. Fifth, the storytelling method facilitates the transfer of moral values, allowing children to understand moral concepts and develop attitudes that are in line with religious teachings. So, the storytelling method practiced by Sunday School teachers has a significant impact on the understanding of the Bible in children aged 3-6 years. This approach is not just about transferring knowledge, but also about shaping the child's character, morality and attitude towards religion. Therefore, it is important for religious educators to consider using the storytelling method in Bible learning for pre-school children in Sunday school.
