Judul: Pengaruh Ketergunaan Teknologi dan Kemandirian Belajar Terhadap Capaian Pembelajaran Saat Program Belajar dari Rumah di Lingkungan Mahasiswa IPB.
Abstrak: Selama pandemi COVID-19 diterapkan program belajar dari rumah (BDR) secara daring. Peran teknologi menjadi penting karena digunakan sebagai media pembelajaran, dan kemandirian belajar juga berperan penting, karena minimnya kehadiran dosen. Secara garis besar penelitian ini bertujuan untuk melihat pengaruh teknologi terhadap kemandirian belajar dan capaian pembelajaran mahasiswa. Responden yang akan diteliti adalah mahasiswa IPB strata sarjana dengan pembagian dua kelompok keilmuan yaitu humaniora dan sains. Analisis hubungan antar variabel menggunakan structural equation model - partial least square. Hasil penelitian mengungkapkan bahwa ketergunaan teknologi berpengaruh positif dan signifikan terhadap kemandirian belajar. Selanjutnya, Kemandirian belajar berpengaruh positif dan signifikan terhadap capaian pembelajaran. Sedangkan variabel ketergunaan teknologi berpengaruh positif secara tidak langsung terhadap capaian pembelajaran, yang berarti ketergunaan teknologi dapat meningkatkan capaiaan pembelajaran mahasiswa melalui kemandirian belajar.

Judul: Dampak Pembelajaran Jarak Jauh (Distance Learning) Terhadap Pencapaian Tujuan Pembelajaran (Studi Kasus Mahasiswa S1 IPB)
Abstrak: Pembelajaran jarak jauh (online) merupakan salah satu solusi metode pembelajaran pada saat pandemi Covid-19. Namun demikian, hasil dari beberapa penelitian mengungkapkan bahwa pembelajaran jarak jauh dapat berdampak negatif terhadap pencapaian tujuan pembelajaran. Berdasarkan informasi tersebut, penelitian ini ditujukan untuk mengungkap lebih jauh faktor-faktor lain yang diduga mempengaruhi pencapaian tujuan pembelajaran yang dilakukan secara online. Penelitian ini melibatkan 201 mahasiswa S1 IPB yang pernah mengikuti kuliah offline dan online yang dipilih secara purposive voluntary sampling technique. Sementara itu Structural Equation Model (SEM) digunakan sebagai basis analisis untuk menduga koefisien model kausalitas antar faktor. Hasil penelitian menunjukkan bahwa pembelajaran secara online signifikan menurunkan kemampuan mahasiswa dalam mencapai tujuan pembelajaran. Dari lima faktor yang mempengaruhi kinerja pembelajaran online, tiga diantaranya yaitu: faktor karakteristik mahasiswa, karakteristik dosen, dan motivasi memiliki pengaruh positif, baik terhadap pembelajaran secara online maupun pencapaian tujuan pembelajaran. Sebaliknya, faktor lingkungan secara langsung berdampak negatif terhadap pembelajaran secara online maupun pencapaian tujuan pembelajarannya. Sedangkan teknologi secara langsung berdampak negatif terhadap pembelajaran secara online dan berdampak positif terhadap pencapaian tujuan pembelajaran. Sehingga secara agregat faktor teknologi dan lingkungan masih belum mampu mendukung pencapaian tujuan pembelajaran yang dilakukan secara online., Distance learning (online) is one of solution to the learning method during the Covid-19 pandemic. However, the results of several studies reveal that distance learning can have a negative impact on the achievement of learning objectives. Based on this information, this research is aimed to reveal further of the other factors that influence online learning objectives. This study involved 201 IPB undergraduate students who had attended offline and online lectures selected by purposive voluntary sampling technique. Meanwhile, the Structural Equation Model (SEM) is used as the basis of analysis to estimate the coefficients of the causality model between factors. The results showed that online learning significantly reduced students' ability to achieve learning objectives. Of the five factors that influence online learning performance, three of them: students characteristic, lecturer characteristics, and students motivation have a positive influence, both on online learning and learning objectives. On the other hand, environmental factors directly have a negative impact on learning and learning objectives. Meanwhile, technology has also a negative impact on online learning but has a positive impact on educational learning objectives. So that in aggregate, technological and environmental factors are still not able to support the learning objectives carried out online.

Judul: Studi sistematika  Oreophryne Boettger, 1895Sulawesi (Anura: Microhylidae)
Abstrak: The cross frogs, genus Oreophryne Boettger, 1895 are most diverse in the mainland of New Guinea and adjacent islands, to the Wallacea region in the Moluccas, Sulawesi, and the Lesser Sunda Islands, even marginally to the Oriental region in Bali and to the southern Philippine Islands. In Sulawesi, this taxon consists of three species but has rarely been reported since their original descriptions and remained unstudied in both taxonomical work and molecular study. This research aims to evaluate the taxonomic status of the cross frogs in Sulawesi based on morphology and estimate the phylogenetic using the 16S rRNA gene. The phylogenetic tree was reconstructed under Maximum Likelihood (ML) and Bayesian Inference (BI) analyses. We used the specimens of Sulawesian Oreophryne which were stored at the Museum Zoologicum Bogoriense (MZB). A total of about 19 morphological characters were measured by a digital caliper and ocular micrometer to the nearest 0.01 mm. The phylogenetic tree shows that the three nominal species of Oreophryne from Sulawesi are clearly clustered. Correspondingly, the phylogenetic analysis supports the recognition of a new taxon, Oreophryne sp. However, the phylogenetic relationships between Oreophryne within Wallacea remain unresolved. Consequently, further systematic analysis along with additional sequences from the type locality is necessary to clarify the interspecific relationship among this region. We examined the morphology of 50 voucher specimens of Sulawesian Oreophryne. The validity of O. celebensis, O. variabilis, and O. zimmeri was confirmed in this study, but still the latter remains to be established. The three nominal species examined here were not collected from the type locality, so additional specimens, either in the type locality, new locations, or in other areas on this island are needed to evaluate the taxonomic status of these species deeply. Moreover, the unnamed species from the highland of the Mekongga mountains differ morphologically and genetically from all previously described Sulawesian Oreophryne. This distinct species will increase the number of cross frogs in Sulawesi to four species, all of which are endemic.
