Pengaruh Media Assemblr EDU Berbasis Augmented Reality terhadap Kemampuan Berpikir Tingkat Tinggi Siswa pada Materi Sistem Ekskresi

Febrianti Putri Lubis — 2024-12-16

The reason of this think about was to decide the impact of Increased Reality-based Assemblr Edu media on students' high-level considering aptitudes within the excretory framework fabric at MAN 2 Mandailing Natal. This consider may be a sort of quantitative investigate with a quasi-experimental plan chosen by cluster irregular choice for the pretest, posttest, and control gather plan. The populace of this consider was four classes of review XI IPA understudies of Madrasah Aliyah Negeri 2 Mandailing Natal, with course XI IPA-I as the exploratory lesson and XI IPA-2 as the control lesson. The investigate instrument was within the frame of ten exposition questions. The autonomous test T test appeared that Ha was acknowledged and H0 was rejected based on the theory test, which delivered a sig esteem (2-tailed) of 0.000 < 0.05 and 0.01. This shows that teaching materials based on Augmented Reality Assemblr Edu have an influence on advanced cognitive abilities

Pengaruh Geotropisme dan Hidrotropisme terhadap Panjang dan Kemunculan Radikula pada Kacang Hijau (Vigna Radiata L) dengan Metode Selang Tunggal

Berri Situmorang — 2024-12-16

Geotropism is the movement of plants influenced by the Earth's gravitational force. Hydrotropism plays an important role for plants by helping to improve access to water, a vital factor for successful plant growth. Mung bean plants are rooted by their root system which is divided into two types, mesophytes and xerophytes. Growth affects the length of mung bean radicle without significantly affecting radicle emergence. This study was conducted with experimental methods using two groups of data: quantitative for radicle length and percentage of radicle emergence; and qualitative data for the direction of radicle growth. Based on the results of the study, it was found that the medium on dry-dry the direction of radicle growth in geotropism samples was positive, namely the direction of the roots towards the center of the earth While wet-dry treated with water limited by cotton, the radicle in geotropism samples was negative, namely the direction of the roots against gratification This is due to the roots being treated with water from the top of the hose which is limited by cotton, so that the roots go towards the water source.

Pengaruh Cahaya dan NaHCO3 terhadap Laju Reaksi Fotosintesis pada Hydrilla verticilata

Marina Azzahra Nasution — 2024-12-16

Fotosintesis merupakan proses penting bagi tumbuhan untuk menghasilkan energi melalui konversi karbon dioksida dan air menjadi glukosa dan oksigen dengan bantuan energi cahaya. Faktor-faktor lingkungan seperti intensitas cahaya, ketersediaan karbon dioksida, suhu, dan konsentrasi air memengaruhi laju fotosintesis. Penelitian ini bertujuan untuk menganalisis pengaruh cahaya dan konsentrasi NaHCO₃ (Natrium Bikarbonat) terhadap kecepatan proses fotosintesis

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.

Pengaruh Perendaman Air Kelapa dalam Pematahan Dormansi Biji Saga (Adenanthera pavonine L) dalam Meningkatkan Daya, Waktu dan Tinggi Kecambah

Novayanti Gultom — 2024-12-16

ABSTRACT

This study aims to determine the effect of soaking Adenanthera pavonina L with various concentrations of coconut water to improve the quality of germinated seeds and determine the best concentration of soaking Adenanthera pavonina in coconut water to maintain the quality of germinated seeds. The research method used was a completely randomized design (CRD) with 4 treatments, namely 1 control and 5 repetitions. The treatments consisted of: K0 = saga seeds without soaking coconut water; K1 = soaking saga seeds in 10% concentration coconut water; K2 = soaking saga seeds in 20% concentration coconut water; K3 = soaking saga seeds in 30% concentration coconut water; and K4 = soaking saga seeds in 40% concentration coconut water. The study showed that soaking Adenanthera pavonina seeds in 10% coconut water had a significant effect on the height of seed germination (3.36 cm) and soaking Adenanthera pavonina seeds in coconut water had no significant difference on seed germination power and seed germination time.

Studi Literatur: Pengaruh Lingkungan Sekolah Terhadap Minat Belajar Peserta Didik Mata Pelajaran Biologi

Forentina Limbong — 2024-12-16

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.
