Peningkatan Motivasi Dan Hasil Belajar Siswa Pada Materi Koordinat Kartesius Melalui Pembelajaran Discovery Learning Berbantuan Powerpoint Interaktif

Mery Kristin Maiten — 2024-11-27

The underlying issue addressed in this research is the low motivation and learning outcomes of students. This is attributed to the conventional teaching model, which is teacher-centered and the use of media that tends to make students passive and uninterested in the learning process. The aim of this study is to describe the improvement in motivation and learning outcomes of 8th-grade students at Catholic Junior High School Muder Teresa on cartesian coordinate material through discovery learning assisted by interactive powerpoint. The research method used is Classroom Action Research (CAR) using the Kemmis and McTaggart model, consisting og 4 stages, namely Planning, Impelemtation, Observation and reflection. Data collection techniques used include observation, interviews, questionnaires tests and documentation. Furthermore, the data were analyzed descriptively. The research result showed in the initial condition average motivation score of students at 53,86. Increasedto 70.5 in first cycle, and 79.64 in the second cycle. While the percentage of students who complated was 57.14% in the first cycle and second cyclewas 89.29%. Thus it can be concluded that the discovery learning model assisted by interactive powerpoint can improve the motivation and learning outcomes of 8^th-grade students at Catholic Junior High School Muder Teresa on cartesian coordinate material.

Penerapan Model Antrian Untuk Mengoptimalisasikan Pelayanan Pada Loket Pengambilan Obat Di Puskesmas Desa Meko

Irmawati Molanu — 2024-11-27

Queuing is a waiting line state where a number of entrants are involved to get services from a service providing facility. One example of queuing activities that are common in the community is taking medicine at the Meko Village Health Center. The purpose of this study was to obtain an optimal queuing model at the drug collection counter at the Meko Village Health Center. Based on the analysis, at this time the service at the drug collection counter at the Meko Village health center that uses queues with a single channel single phase (M/M/1) model is not optimal. To optimize services, the application of the multi-channel single phase multiple line queue model (M/M/c) where c = 3 results in a measure of system performance, namely the probability of no customers in the system ( ) is 0.034 = 3.4%, the service utility rate (ρ) is 0.866 = 86.6%, number patient in the queue ( ) is 5 customers, number patient in the system ( ) is 8 customers, waiting time in the queue ( ) is 22,38 minutes, and waiting time in the system ( ) is 34,38 minutes. By applying the multi-channel single phase (M/M/c) multiple line queue model, it becomes an alternative solution in providing good and optimal service to patients at the Meko Village health center.

This study aims to analyze the level of mathematics anxiety and the factors that cause mathematics anxiety in terms of neuroscience. The research method used is qualitative research with a qualitative descriptive approach. The research subjects were 31 students of class XII of SMA Swasta Bintang Timur 1 Balige. Data on the level of math anxiety was obtained through a literature study assisted by a questionnaire to determine the factors that affect math anxiety according to neuroscience. The results showed that 18 students experienced high levels of math anxiety and 13 other students experienced moderate levels of math anxiety. Students experience the most math anxiety from a cognitive perspective as shown by a percentage of 37.1% and the symptoms that are often felt are often forgetting formulas and feeling overwhelmed when doing math tasks that require a high level of thinking. From a neuroscience point of view, cognitive math anxiety is influenced by the neocortex; math anxiety based on personality factors is influenced by the autonomic nervous system; and math anxiety from social factors is influenced by the anterior cingulate cortex (ACC) brain network.
