Abstract

Photosynthesis is an important process for plants to produce energy through the conversion of carbon dioxide and water into glucose and oxygen with the help of light energy. Environmental factors such as light intensity, carbon dioxide availability, temperature, and water concentration affect the rate of photosynthesis. This study aims to analyze the effect of light and NaHCO₃ (Sodium Bicarbonate) concentration on the speed of photosynthesis process in plants. One way to increase the availability of carbon dioxide for plants is by adding NaHCO₃ (Sodium Bicarbonate) solution. In this experiment, variations in light intensity, irradiation time and NaHCO₃ concentration were used to observe the rate of photosynthesis as measured by changes in the amount of oxygen produced. The results of this study indicate that both light and NaHCO₃ have an important role in influencing the rate of photosynthesis, but there is an optimal limit where further increase does not give significant results.

Abstract

Education fosters students' curiosity and enthusiasm for learning. As a psychological aspect, interest in learning plays an important role by evoking a sense of enjoyment and comfort in learning without external pressure. This study focuses on the influence of school environment conditions on students' interest in learning, including factors such as physical facilities, classroom atmosphere, teacher-student interaction, and parental support. The research method used was a literature review, involving a collection of relevant studies from PubMed and Google Scholar published between 2021 and 2023, using the keywords "learning interest" and "school environment".These findings reveal that the school environment significantly contributes to increasing interest in learning. Adequate facilities, a supportive classroom atmosphere, and positive teacher-student relationships effectively encourage greater interest in learning.

Abstract

Penelitian ini bertujuan untuk mengetahui karakteristik pasien serta pemberian Vaksin Anti Rabies (VAR) pada kasus gigitan hewan di Puskesmas Kota Medan tahun 2024. Penelitian ini menggunakan metode deskriptif dengan pendekatan kuantitatif dan dilaksanakan pada Maret 2025. Sampel terdiri dari 50 pasien yang dipilih menggunakan teknik purposive sampling, dengan kriteria hanya pasien yang menerima VAR. Hasil penelitian menunjukkan bahwa mayoritas pasien yang menerima VAR adalah perempuan (59,09%). Kelompok usia yang paling banyak terdampak adalah dewasa (54,55%). Luka gigitan paling sering ditemukan pada bagian kaki (34,00%). Selain itu, jumlah total kunjungan pasien untuk menyelesaikan jadwal Post-Exposure Prophylaxis (PEP) hingga pemberian VAR ke-3 mencapai 150 kunjungan.
