Persepsi Guru tentang Program Sertifikasi dalam Peningkatan Kompetensi Pedagogik di SDN Meruya Selatan 01 Pagi

The goal to be achieved in this study is to teacher’s perceptions of the certification program in enhancement pedagogical competence at Meruya Selatan 01 Elementary School Am. The method used in this research is descriptive quantitative. The population in this study were all teachers at Meruya Selatan 01 Elementary School am, totaling 25 teachers. Sampling was carried out using saturated sampling technique, in which the entire population was used as a sample. The data collection technique uses closed questionnaires. Data analysis in this study was carried out in a simple quantitative descriptive manner using intervals and percentages. The results showed that the majority of teachers' perceptions of the certification program were very good, obtained from 16 (64%) teachers who answered. In the implementation of pedagogic competence, there were 7 (28%) teachers doing it quite well. This is a pretty good discovery in the school environment, because it means that the teacher certification program pursued by the government with the aim of increasing competency is going quite well or there are still results, although not optimal. However, it should also be noted that teachers who have very good perceptions of the certification program do not always have very good pedagogical competence. In fact, from the results of the study, it was found that there were more teachers whose pedagogical competence was only in the fairly good category. This is also a note for teachers to be more creative in improving their competence

The Role of Leaf Characters of Peanuts on Whitefly (Bemisia tabaci Genn.) Infestation

Kutu kebul Bemisia tabaci Genn. merupakan salah satu hama utama pada tanaman kacang tanah. Karakter morfologi tanaman merupakan pertahanan awal suatu tanaman dalam menghadapi serangan hama. Kesesuaian antara karakter morfologi daun dengan perilaku serangga hama menentukan peletakan telur oleh imago kutu kebul B. tabaci. Penelitian ini bertujuan untuk mengetahui karakter morfologi daun kacang tanah yang menentukan kepadatan populasi kutu kebul. Penelitian dilaksanakan di rumah kaca pada Balai Penelitian Tanaman Aneka Kacang dan Umbi (Balitkabi) mulai bulan Nopember 2019 hingga Februari 2020. Penelitian menggunakan 10 genotipe kacang tanah yang disusun berdasar rancangan acak kelompok (RAK) dan diulang tiga kali. Variabel pengamatan adalah karakter daun, tebal lapisan lilin, epidermis, mesofil, dan daun total, luas daun, kerapatan trikoma, panjang trikoma, jumlah vena, warna daun, kandungan klorofil, dan populasi imago pada 50, 60, dan 70 hari setelah tanam (HST). Hasil penelitian menunjukkan bahwa tebal mesofil daun, tebal daun total, jumlah vena, dan panjang trikoma berbeda nyata antargenotipe serta menunjukkan korelasi positif dengan populasi kutu kebul. Sebagian besar genotipe kacang tanah mempunyai warna daun kuning kehijauan dengan kode 2880 U, dengan kandungan klorofil a, klorofil b, dan karotenoid pada daun masing-masing antara 86,65 – 160,73 mg/m2, 64,43 – 99,70 mg/m2, dan 690,82 – 1290,65 mg/m2. Sidik Lintas menunjukkan bahwa tebal daun, tebal mesofil, dan panjang trikoma berpengaruh langsung pada populasi kutu kebul, sedangkan jumlah vena berpengaruh tidak langsung. Dengan demikian, daun yang tebal dengan mesofil tebal, memiliki lapisan lilin dan trikoma panjang serta jumlah vena rapat lebih disukai imago kutu kebul untuk meletakkan telur

Environmental Enrichment and Aerobic Exercise Enhances Spatial Memory and Synaptophysin Expression in Rats

BACKGROUND: Exposure to environmental enrichment has a positive effect on brain function, including improved cognition. Environmental enrichment has many aspects, including social interactions, object stimulations, and physical activities. Exercise and environmental enrichment can be considered to improve cognitive function with different underlying mechanisms. This study aims to compare the effects of environmental enrichment and aerobic exercise at both synaptic and whole-organism levels using synapyophysin as a measure of synaptic physiology and spatial memory as a measure of cognitive function.METHODS: A six-week in vivo experimental study on 15, 6-month old male Wistar rats randomly divided into three groups (n=5): aerobic group (A), enriched environment group (EE), and enriched with an aerobic or combined group (EEA). All rats were tested four times in the Water-E maze (WEM) task at weeks 0, 2, 4, and 6 of the study. We used immunohistochemistry to determine the synaptophysin expression in hippocampal CA1 region.RESULTS: Based on synaptophysin immunostaining, there were higher optical density scores for synaptophysin in hippocampal CA1 region following EEA, but there were no statistically significant differences between groups (ANOVA test, p>0.05). The spatial memory test showed there were significantly reduced travel time and total errors from the 2nd and 4th weeks in the EEA group, respectively (p<0.05).CONCLUSION: The combination of enriched environment and aerobic exercise seems to rapidly improve spatial memory and enhances the presynaptic protein, synaptophysin in hippocampal CA1 region.KEYWORDS: aerobic exercise, environmental enrichment, spatial memory, synaptophysin, Water-E maz
