Judul: The Effectiveness of Online Learning during Pandemic (Cases: Students of Communication and Community Development Sciences IPB)
Abstrak: Adaptasi cara pembelajaran terhadap pandemi Covid-19 berpotensi merubah kebiasaan sehari-hari menjadi kebiasaan baru. Pemerintah Indonesia pun membuat beberapa kebijakan untuk memutuskan rantai penyebaran Covid-19, salah satunya yaitu belajar dari rumah menggunakan komunikasi daring. Seluruh instansi pendidikan mengikuti kebijakan tersebut termasuk Institut Pertanian Bogor. Tujuan dari penelitian ini adalah menganalisis karakteristik belajar daring mahasiswa Sains Komunikasi dan Pengembangan Masyarakat (SKPM) dan analisis strategi belajar daring mahasiswa serta untuk mengetahui hubungan dua variabel tersebut dengan keefektifan kegiatan belajar daring. Penelitian ini menggunakan pendekatan kuantitatif (survei) yang didukung oleh data kualitatif. Data kuantitatif dikumpulkan dengan menggunakan kuesioner di Google Form. Data kualitatif dikumpulkan dengan wawancara mendalam terhadap informan dan responden dengan menggunakan pedoman wawancara. Hasil penelitian menunjukkan bahwa tingkat keefektifan belajar daring mata kuliah ELKS cenderung tergolong tinggi. Terdapat dua aspek karakteristik belajar daring yang berkorelasi dengan tingkat keefektifan belajar daring yaitu aspek kepemilikan alat komunikasi dan motivasi. Pada variabel strategi pembelajaran daring terdapat tiga aspek yang berkorelasi dengan tingkat keefektifan belajar daring yaitu infrastructure, learning resources, dan learning and teaching methods.

Judul: Factors Affecting Bogor Agricultural  University Students' Academic Achievement in Online and Offline Learning
Abstrak: Meski pandemi Covid-19 telah berlalu, penerapan pembelajaran daring sebagian masih terus berlanjut. Alasan utamanya adalah, sistem ini memiliki fleksibilitas yang tinggi serta infrastruktur penunjangnya semakin baik, sehingga sistem perkuliahan hibrid menjadi suatu pilihan. Keberhasilan aktivitas perkuliahan tidak saja ditentukan oleh sistem perkuliahan yang digunakan namun terdapat faktor lainnya, baik dari sisi mahasiswa maupun institusi pendidikan, seperti faktor inteligensi, motivasi, kebiasaan, emosi, lingkungan belajar, lingkungan sosial, sarana kampus, dan sarana daring. Penelitian ini ditujukan untuk menguji pengaruh faktor-faktor tersebut terhadap prestasi belajar. Penelitian ini melibatkan 170 mahasiswa S1 Institut Pertanian Bogor yang mengikuti kuliah daring dan luring. Pengumpulan data dilakukan melalui voluntary sampling techniques, dimana kuesioner disampaikan melalui media sosial kepada target responden. Structural Equation Modeling digunakan untuk menduga koefisien model yang menjelaskan hubungan kausalitas antara prestasi belajar dengan faktor-faktor yang memengaruhinya. Hasil penelitian menunjukan, inteligensi mahasiswa menjadi faktor yang paling berpengaruh terhadap prestasi diikuti faktor lingkungan sosial., Although the COVID-19 pandemic has passed, the implementation of online learning continues partially. The main reasons are the high flexibility of this system and the improvement of supporting infrastructure, making the hybrid learning system a viable option. The success of lecture activities is not only determined by the lecture system used but also by other factors from both students and educational institutions, such as intelligence, motivation, habits, emotions, learning environment, social environment, campus facilities, and online facilities. This study aims to examine the influence of these factors on academic achievement. The study involved 170 undergraduate students from Bogor Agricultural University who participated in both online and offline learning. Data collection was conducted through voluntary sampling techniques, where questionnaires were distributed via social media to the target respondents. Structural Equation Modeling was used to estimate the model coefficients that explain the causal relationships between academic achievement and the influencing factors. The results show that student intelligence is the most influential factor on academic achievement, followed by the social environment factor.

Judul: Posisi Filogenetik Kura-Kura Carettochelys Insculpta  (Reptillia: Testudinata)
Abstrak: Carettochelys insculpta is an endemic freshwater turtle of southern Papua and northern Australia. Phylogenetic position of this turtle is remain unresolved until now. Most of the research conducted show close relationships of C. insculpta and members of Trionychidae family. However, some of the research show distance between C. insculpta and members of Trionychidae family. This research is conducted to analyze phylogenetic relationship between C. insculpta and other members of Testudinata using 12S rRNA, 16S rRNA, and both gene as markers. DNA samples were obtained from three different organisms of C. insculpta. Two species used as outgroups were Alligator mississippiensis and Iguana iguana. Phylogenetic analysis was carried out using Neighbor-Joining method with Felsenstein 1981 (F81) modeltest. A polytomy tree of Testudinata was produced by using 12S rRNA gene. However, analysis using 16S rRNA and both genes as markers confirmed that C. insculpta was located between the Chelonidae and the Trionychidae family.
