Abstract

Tujuan dari penelitian ini adalah untuk mengetahui pengaruh dari kurs, utang luar negeri, penanaman modal asing di Indonesia tahun 2000-2023, dengan menggunakan data sekunder dari publikasi Badan Pusat Statistik, Bank Indonesia (BI) dan dianalisis menggunakan metode analisis regresi linier berganda program eviews 12. Hasil analisis menunjukkan kurs memiliki perngaruh positif tidak signifikan terhadap cadangan devisa di Indonesia tahun 2000-2023, utang luar negeri memiliki pengaruh positif tidak signifikan terhadap cadangan devisa di Indonesia tahun 2000-2023, kemudian penanaman modal asing memiliki pengaruh positif signifikan terhadap cadangan devisa di Indonesia tahun 2000-2023. Koefisien Determinasi (R2) sebesar 0,782008 maka dapat dikatakan bahwa variabel bebas dapat menjelaskan keberagaman variabel tak bebas sebesar 78,2008%. Berdasarkan kesimpulan tersebut pemerintah dan Bank Indonesia harus dapat menerapkan kebijakan yang dapat menstabilkan nilai tukar rupiah (kurs), kemudian utang luar negeri dimanfaatkan sebaik mungkin terutama untuk investasi sektor-sektor yang akan berkontribusi dalam peningkatan cadangan devisa.

Abstract

Antibiotic resistance is a global health issue largely caused by the misuse of antibiotics. Increasing public knowledge about rational antibiotic use is a key step in controlling antimicrobial resistance. This study aimed to determine the effect of educational content on the social media platform TikTok on students’ knowledge about antibiotics at Universitas Islam Indonesia. The research employed a pre-test–post-test design, with a 63-second educational video as the intervention. The study involved 351 students selected through accidental sampling. The research instrument was a questionnaire that had been tested for validity and reliability. The results showed a significant increase in the average knowledge score from 73.25% in the pre-test to 91.16% in the post-test (p < 0.05). These findings indicate that TikTok-based educational content effectively improves students’ understanding of appropriate antibiotic use. Social media can serve as an engaging and accessible platform for health education, especially among young people. Utilizing TikTok as a medium for health promotion is expected to support national efforts in preventing antimicrobial resistance in Indonesia.

Abstract

Produktivitas nilam (Pogostemon cablin Benth) sebagai salah satu tanaman penghasil minyak atsiri dapat ditingkatkan dengan penggunaan pupuk hayati dan pupuk organik. Tujuan penelitian ini adalah untuk mengetahui pengaruh FMA dan pupuk organik terhadap kolonisasi FMA dan kadar hara tanaman nilam. Penelitian ini menggunakan rancangan acak kelompok (RAK) pola faktorial dengan dua faktor yang diuji dan tiga ulangan. Faktor pertama adalah FMA (tanpa FMA, A. tuberculata dan Glomus sp), sedangkan faktor kedua adalah dosis pupuk organik (0, 10, dan    20 t ha-1). Hasil penelitian menunjukkan bahwa A. tuberculata memberikan pengaruh lebih tinggi terhadap kolpnisasi FMA, Glomus sp.memberikan pengaruh lebih besar terhadap kadar nitrogen (N) dan fosfor (P). Kedua spesies FMA tersebut memberikan pengaruh yang sama terhadap kadar kalium (K) tanaman.  Peningkatan dosis pupuk organik menurunkan kolonisasi FMA namun meningkatkan kadar N, P, dan K tanaman.  Kedua spesies FMA tersebut memberikan respon negatif terhadap tingginya dosis pupuk organik dalam mempengaruhi kolonisasi FMA. Aplikasi pupuk organik mengurangi pengaruh A. tuberculata terhadap kadar K tanaman, namun sebaliknya dengan Glomus sp.  Hasil penelitian ini menunjukkan FMA dan pupuk organik,  tanaman baik sebagai aplikasi tunggal maupun ganda,  merupakan strategi untuk meningkatkan produktivitas tanaman nilam.

Abstract

Student learning outcomes should be the main focal point in learning. Good learning outcomes show the level of students' understanding of the teaching material, as well as the success of teachers in carrying out learning in the classroom. The study aims to determine the differences in student learning outcomes taught using LKS Kharisma and LKS PAIKEM on the material of the human circulatory system. The type of research used is quantitative, namely a comparative study or comparative study with a total sample of 38 people. The sample was selected using the cluster random sampling technique. The instruments used are tests and observations. Tests are carried out to determine student learning outcomes and observation is used to objectively determine learning conditions. The data analysis technique used is to use the t-test. The results of the analysis showed that there were differences in student learning outcomes taught using LKS Kharisma and LKS PAIKEM on the material of the human circulatory system. The average score of students who studied using LKS PAIKEM was 73.84 and students who studied with LKS Kharisma obtained an average score of 64.74

Abstract

This study aims to determine the improvement of biology learning outcomes through the application of the Student Teams Achievement Divisions (STAD) type cooperative learning model to grade VIII students of SMP Negeri 4 Salahutu. The type of research used is Classroom Action Research which consists of four stages, namely planning, implementation, observation, and reflection. The subjects of this study numbered 34. The instruments used are observation sheets, learning outcome tests, and documentation. Based on the results of data analysis, it was found that the application of the STAD type cooperative learning model can improve student learning outcomes in grade VIII SMP Negeri 4 Salahutu. These results are intended by increasing the results of the initial test, cycle I, and cycle II tests. This is shown from the results obtained by students who have achieved the Minimum Completeness Criteria individually, namely 67 and classically the completeness of student learning reaches 75% of students who are complete. In the initial test, the percentage of student learning completeness only reached 26.47% and increased in the first cycle test to 64.71%, and again increased in the end of the second cycle test to 94.12%. While the average score obtained classically also increased, namely in the initial test the average value obtained was 52.65, there was an increase in cycle I to 69.12 and increased significantly in cycle II to 83.24.

Abstract

Several types of aquatic plants are known to have the ability to improve water quality. The application of phytoremediation to domestic waste can significantly reduce Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), ammonia, nitrate, and phosphate levels, as well as increase dissolved oxygen (DO) levels in the water, thus improving water quality and making it suitable for aquatic organisms. This study investigated the efficacy of three aquatic plants Water Spinach (Ipomoea aquatica), Watercress (Nasturtium officinale), and Genjer (Lemna minor) in enhancing the quality of domestic wastewater. The experiment was conducted in a controlled environment at the Greenhouse facility of Universitas Advent Indonesia, utilizing seven containers stocked with domestic wastewater and catfish specimens. Treatments consisted of systems with and without the incorporation of these aquatic plants. Results demonstrated that all three plants significantly ameliorated water quality parameters, including reductions in Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), and Total Suspended Solids (TSS), alongside elevations in pH and Dissolved Oxygen (DO) levels. Notably, Ipomoea aquatica exhibited superior performance, yielding the highest catfish survival rates. These outcomes underscore the potential of integrating aquatic plants into aquaponic systems as aviable, environmentally sustainable approach to domestic wastewater remediation.
