The principles of chemistry learning emphasize that students study chemical concept in a structure and detailed manner. Until now, chemistry lessons are still a big challenge for teachers, because students often experience difficulties when learning chemical concept such as the concept of stoichiometry. This study aims to determine the level of concept understanding and the percentage of students' concept understanding on stoichiometry material using a five tier diagnostic test. The method used in this research is descriptive qualitative. The results showed: (1) the average level of students' concept understanding is classified in the category of lack of knowledge (LK); (2) the average percentage of students who understand the concept (SC) is 13.0% and the sub-concept with the highest percentage of understanding the concept (SC) is Relative Molecular Mass which is 33.0%. Of the 15 questions tested, question number 1 has the highest percentage of understanding the concept (SC) of 33.0%, while for the other 14 questions the average student is classified in the category of lack of knowledge (LK). It can be concluded that students' concept understanding on stoichiometry material is still classified as very low criteria.

Amanna Gappa is the third Matoa of Wajo. He formulated a maritime law known as Amanna Gappa, which was enacted in 1676. This law discusses the rules for trading and sailing during that time. Three hundred years later, a modern maritime law was established, known as the United Nations Convention on the Law of the Sea (UNCLOS). The research method used is qualitative research utilizing secondary data through literature studies such as documents, articles, reports, scientific journals, and internet sites. The collected data is then analyzed to produce descriptive information presented by the author in the form of sentences and words that support explanations related to the research.The laws within Amanna Gappa's maritime law consist of 21 articles and cover various matters, both technical and non-technical. It outlines efforts to achieve welfare on board ships, detailing the rights and obligations of everyone involved. This is quite similar to UNCLOS; however, its orientation is more towards the state, focusing on how UNCLOS seeks to regulate national welfare at sea. The values that continue to be upheld in current maritime law emphasize that regulations should be made as much as possible for the sake of welfare and justice.
