This study focused on creating an innovative learning tool – a rotating solar system model – to help sixth-grade elementary students in Natural Sciences (IPA) better understand the solar system. We identified key challenges in teaching this topic: students often showed low interest and struggled with the abstract concepts of planetary movement. To address these issues, we used a Research and Development (R&D) approach following the ADDIE model (Analysis, Design, Development, Implementation, and Evaluation). The rotating solar system model was designed as a three-dimensional teaching aid that students could manually rotate. This simple yet educational design visually demonstrates the orbit and rotation of planets around the sun. During development, we consulted with subject matter experts and media experts to ensure the content's accuracy and visual quality. Validation results were highly positive, with average scores of 88% from subject experts, 83% from media experts, and 92% from practitioners, all categorized as "good." We then conducted a limited trial with 29 sixth-grade students at SD Negeri 222 Palembang. The results were encouraging: we observed a significant improvement in conceptual understanding, as evidenced by pre-test and post-test score comparisons, as well as an increase in student motivation during the learning process. 

Skin diseases are health problems that require accurate diagnosis to evaluation and ultimately leading to treatment decisions. One of the crucial roles in the diagnostic process is medical imaging. Machine learning technology can assist in classifying skin diseases using image data and achieving high levels of accuracy in diagnosis. The purpose of this research is to review machine learning algorithms that can be utilized to develop image-based skin disease classification systems. The methodology employed is a Systematic Literature Review (SLR), which can be used to provide a comprehensive review of the application of machine learning in the classification of skin diseases. The literature search strategy was based on the Boolean technique, applied to the Scopus database. The selected articles were screened using predefined inclusion and exclusion criteria.

This study aims to analyze the legal implications of granting building use rights to foreign nationals under the Job Creation Law. The main problem that currently occurs is the limited availability of land in Indonesia, while development is progressing rapidly, especially in urban areas. To meet the needs of the community, including foreign citizens, for housing, the government then took the path of building flats as part of housing development, considering the limited land in urban areas. In its development, the government then enacted the Job Creation Law, which turned out to be inconsistent with previous regulations. This is interesting to study regarding the impact that will occur if Building Use Rights are granted to Foreign Citizens living in Indonesia, so that the problems that arise can be in the form of legal certainty of the Job Creation Law regarding ownership of Building Use Rights by Foreign Citizens and ownership of flat units by Foreign Citizens according to the Job Creation Law linked to the principle of nationality. This study uses a normative legal approach method by reviewing library materials or secondary data, and the nature of this research is descriptive and analytical. The results of the study concluded that the legal certainty of ownership of Apartment Ownership Rights on land with building use rights by foreigners based on the Job Creation Law is still not guaranteed, because in the UURS and UUPA, foreigners can only have usage rights, while in the UUCK, they can have HGB. The novelty of this study lies in its normative analysis of conflicting regulations and the identification of legal gaps in the implementation of foreign ownership of apartment units.
