Abstract

Daun ketapang (Terminalia catappa) merupakan salah satu bahan alami yang bisa dimanfaatkan untuk menurunkan pH. Penelitian ini bertujuan untuk mengetahui pengaruh serta mendapatkan dosis terbaik larutan daun ketapang terhadap perbaikan parameter kimia air media pertumbuhan ikan jelawat. Metode yang digunakan adalah metode eksperimen dengan Rancangan Acak Lengkap (RAL) empat taraf perlakuan dan tiga kali pengulangan. P0 (kontrol), Penggunaan larutan daun ketapang dengan dosis 2 g/L (P1), P2 dosis 4 g/L, P3, dosis 6 g/L. Daun ketapang diblender hingga menghasilkan bubuk halus, selanjutnya bubuk halus ditimbang masing-masing, yaitu 20 g, 40 g, dan 60 g, kemudian dilarutkan menggunakan air panas dengan suhu 100°C sebanyak 1 L untuk masing-masing perlakuan, diaduk dan seduhan disaring. Larutan berupa cairan dimasukkan ke dalam wadah pemeliharaan dengan volume air 9 L/perlakuan. Pemberian larutan daun ketapang memberikan pengaruh nyata terhadap perbaikan parameter kimia air media pertumbuhan ikan jelawat. Perlakuan dosis terbaik adalah P2 dengan menghasilkan pertumbuhan berat mutlak sebesar 1,46 ±0,57 g, dan panjang mutlak sebesar 0,93 ±0,57 cm.

Abstract

Located in Central Java Province, Semarang City is one of Indonesia’s major urban centers. As a type of paradiplomacy, the Regional Government of Semarang City has established sister city relationships with the governments of Brisbane (Australia), Beihai, Nanjing, and Fuzhou (China), Split (Croatia), and Jung-gu, Ulsan Metropolitan City (South Korea). At the office of the Mayor of Jung-gu in Ulsan Metropolitan City, South Korea, the Governments of Semarang and Jung-gu signed a point of cooperation formalizing their sister city relationship. Shared interests, exchanging potentials, reciprocal relationships, being actively oriented toward the community, the existence of short- and long-term strategic benefits, exclusivity and closeness in the sense of not having a sister city relationship with other cities, and stable political conditions in the country where the sister city was located were all principles that should be prioritized in carrying out this cooperation. The historical foundations of the diplomatic relationships between Semarang and Jung-gu were bolstered by infrastructure and natural resources facilitating and encouraging further development of the two cities’ previously substantial relations.

Abstract

Education is a process in which there are rules and procedures that every student must have. Improving the quality of education requires student learning independence in the learning process. Participants in this research were all students of the Dharma Patra Pangkalan Berandan Private High School in Sei Lepan sub- district, Langkat district, totaling 497 students. The quantitative method approach used in this research is an explanatory or explanatory quantitative approach. Based on the research results which show a CR value of 2,647 > 1.96 and a P value of < 0.05, it can be concluded that there is a significant influence between subjective well-being and learning motivation. In other words, students who have a higher level of subjective well-being tend to have stronger learning motivation. The relationship between subjective well-being and learning motivation is complex and influenced by various factors. However, the results of this study emphasize the importance of paying attention to students' emotional well-being and life satisfaction as an integral part of strategies to increase student motivation and learning outcomes.
