Perbandingan Pupasi Dua Jenis Kupu-kupu Troides Helena Dan Pachliopta Aristolochiae (Lepidoptera: Papilionidae)

T. helena dan P. aristolochiae merupakan spesies kupu-kupu yang memakan tanaman pakan yang sama (Aristolochia tagala) pada fase larva. Ketika akan memasuki fase pupa, larva kupu-kupu T. helena dan P. aristolochiae mengalami pupasi yang diawali dengan aktifnya hormon prothoracicotropic (PTTH) yang memicu larva untuk berhenti makan. Penelitian ini bertujuan untuk membandingkan tahapan dan waktu yang dibutuhkan dari awal pupasi hingga terbentuk pupa dari dua jenis kupu-kupu. Penelitian dilakukan pada bulan Januari 2016 di Taman Kupu-kupu Gita Persada Lampung. Sepuluh larva instar terakhir T. helena dan P. aristolochiae hasil penangkaran diamati aktivitasnya setiap satu jam hingga terbentuk pupa, serta pengukuran panjang benang dan penimbangan berat pupa. Data yang diperoleh dianalisis secara deskriptif, uji t (Independent Sample Test), dan analisis korelasi untuk panjang benang dan berat pupa. Hasil menunjukkan bahwa pada awal memasuki pupasi, larva instar terakhir T. helena dan P. aristolochiae memiliki aktivitas yang sama, yaitu berhenti makan dan mencari tempat yang cocok yang akan digunakan sebagai tempat menggantung. Larva memendekkan tubuhnya, membuat benang, menggantung dan kemudian membentuk pupa. Pembuatan benang T. helena dan P. aristolochiae terjadi pada malam hari. Hasil analisis uji t menunjukkan bahwa rata-rata lama pupasi kupu-kupu T. helena dan P. aristolochiae berbeda nyata ( < 0,03), rata- rata pupasi T. helena 4,8 jam lebih lama dibandingkan P. aristolochiae. Adanya korelasi positif antara panjang benang dan berat dengan nilai r T. helena : 0,94 dan r P. aristolochiae : 0, 6

BIJI MINDI (Melia azedarach L.) SATU ALTERNATIF PENGENDALI ULAT GRAYAK (Spodoptera litura F.) DAN KUTU DAM KEDELAI (Aphis glycines Mats.)

Telah dicoba menggunakan biji mindi, Melia azedarach untuk mengetahui kemampuannya dalam menekan populasi hama kedelai yaitu ulat grayak Spodoptera litura F. dan kutu daun kedelai Aphis glycines Mats. Dibuat dua seri larutan yang disiapkan dari biji mindi segar dan ekstraknya yang diperoleh dengan ekstraksi menggunakan etanol. Pengujian larutan seri dilakukan terhadap hama-hama tersebut dengan mengamati mortalitas dan kemauan makan setelah 24 jam perlakuan. Biji mindi segar dan ekstraknya mengurangi kemauan makan ulat grayak Spodoptera litura F. Pengaruh biji mind! segar dalam mengurangi kemauan makan ulat grayak lebih nyata diban¬dingkan dengan ekstrak biji mindi. Biji mindi segar dan ekstraknya bersifat toksik terhadap ulat grayak Spodoptera litura F. dan kutu daun kedelai Aphis glycines Mats. Biji mindi dapat dimanfaatkan sebagai alternatif pengen¬dali ulat grayak dan kutu daun kedelai. Pemanfaatan biji mindi sebagai pengendali hama lebih dianjurkan dalam bentuk segar mengingat segi praktis dan ekonomis. Aplikasi biji mindi untuk pengendalian hama dilapangan perlu diteliti lebih lanjut

Computational design of disulfide cyclic peptide as potential inhibitor of complex NS2B-NS3 dengue virus protease

Development of genomic and proteomic studies coupled with computational sciences could facilitate the discovery of various target proteins and potential inhibitor to be developed as drugs. Several researches by molecular docking method have been conducted to design disulfide cyclic peptide ligand as potential inhibitors for NS2B-NS3 protease (NS2B-NS3 pro) of dengue virus serotype DENV-2 in order to inhibit replication of dengue virus. This research studied and evaluated the interaction of ligands and the enzyme in the hydrate state using molecular dynamics simulations at two different temperatures. Simulations were performed using two disulfide cyclic peptide inhibitors KRK and RKR, along with one linear peptide Bz-Nle-K-R-R-H as standard ligand. The result shows that dynamic movement of three proposed ligand in hydrated state affects ligand interactions. RKR ligand has the best affinity with the enzyme than KRK and standard ligand. This is shown by the ligand interaction with enzyme active site which remains stable during the simulation. At the end of simulation 300 K, RKR formed a hydrogen bond with Asp75 and at the end of simulation 312 K, RKR also maintained hydrogen bond with Asp75Key words: Dengue virus (DENV), serine protease NS2B and NS3, molecular docking, molecular dynamics

Роль родительского участия и оценка учащимися начальной школы своих знаний по математике при онлайн-обучении

Introduction. Learning mathematics from home during the COVID-19 pandemic is a challenge for both parents and students to manage to engage in learning. Therefore, it is important to examine the involvement of parents in learning mathematics from home and students’ mathematics self-concepts and their relationship to mathematics performance. Aim. This study is aimed to analyse parental involvement and students’ mathematical self-concept, the relationship between the two, and their effect on students’ mathematical performance in online learning. Methodology and research methods. A cross-sectional survey was used to achieve the research objectives. There were 56 elementary school students in rural areas who were involved in this study. To assess parental involvement and mathematics self-concept, the authors employed questionnaires. Meanwhile, the results of the mid-semester test were used to assess student math performance. The answers to the research questions were reported using descriptive analysis, correlation, regression, and the t-test. Results. Based on the results of the analysis, parental involvement, both in terms of support and control aspects, has a significant influence on mathematics performance. On the other hand, mathematics self-concept and performance positively influence each other. The findings of the present research also show that the gender group and grade level group did not have significant differences for each variable. Practical significance. This study has implications for schools to maximise parental involvement in their children’s mathematics learning effectively. Communication between schools, teachers, and children, in particular, becomes critical to maximise children’s potential, including their math self-concept.Введение. Изучение математики дома во время пандемии COVID-19 является сложной задачей как для родителей, так и для школьников, которым необходимо научиться участвовать в образовательном процессе. Поэтому важно исследовать участие родителей в изучении математики дома, а также оценивание школьниками своих знаний по математике и их отношение к успеваемости по этому предмету. Цель исследования – проанализировать участие родителей в изучении математики, оценивание школьниками своих знаний по этому предмету, роли и взаимосвязи между данными аспектами, а также влияние на успеваемость учащихся по математике при онлайн-обучении. Методология и методы исследования. Для достижения поставленной цели был использован перекрестный опрос. В исследовании приняли участие 56 учащихся начальной школы из сельской местности. Для оценки участия родителей и оценивания школьниками своих знаний по математике авторы использовали анкеты. Между тем результаты тестов в середине семестра использовались для оценки успеваемости учащихся по математике. Ответы на вопросы исследования сообщались с использованием описательного анализа, корреляции, регрессии и t-критерия Стьюдента. Результаты. По результатам анализа участие родителей с точки зрения как поддержки, так и контроля оказывает существенное влияние на успеваемость по математике. С другой стороны, оценивание школьниками своих знаний по математике и успеваемость положительно значимо влияют друг на друга. Результаты исследования также показывают, что гендерная группа и группа класса в этом исследовании не имели существенных различий по каждой переменной. Практическая значимость. Это исследование имеет значение для школ, чтобы максимизировать участие родителей в эффективном изучении математики их детьми. Общение между школами, учителями и детьми, в частности, становится критически важным для максимального раскрытия потенциала детей, включая оценивание школьниками своих знаний по математике.The authors would like to thank all participants for their time and willingness to participate in the survey. Grateful thanks are also extended to the anonymous reviewers for their thoughtful and constructive suggestions on a draft of this paper.Авторы благодарят всех участников, которые нашли время пройти опрос. Авторы также выражают благодарность анонимным рецензентам за их вдумчивые и конструктивные предложения, которые значительно помогли улучшить качество публикации
