Abstract

Gastropoda air tawar merupakan makrozoobenthos yang memiliki peran penting bagi makhluk hidup, salah satunya dijadikan sebagai konsumsi makanan bagi manusia ataupun sebagai pakan ternak bagi hewan. Selain memiliki manfaat, beberapa jenis gastropoda air tawar menjadi hospes perantara untuk menyempurnakan siklus hidup bagi cacing Trematoda yang dapat menyebabkan penyakit bagi manusia ataupun hewan yang memakannya. Penelitian ini bertujuan untuk mengetahui keanekaragaman gastropoda air tawar dan menganalisis adanya cacing Trematoda yang ditemukan di Situ Gede dan Situ Cibeureum Kota Tasikmalaya. Metode yang digunakan yaitu survei dengan pendekatan kualitatif. Teknik analisis data menggunakan beberapa indeks ekologi diantaranya kelimpahan kumulatif, kelimpahan relatif, indeks dominansi, indeks keanekaragaman Shannon-Weiner, indeks keseragaman, dan prevalensi cacing Trematoda. Berdasarkan hasil penelitian yang diperoleh di Situ Gede terdapat enam jenis gastropoda air tawar dan dua jenis cacing Trematoda, sedangkan di Situ Cibeureum hanya terdapat tiga jenis gastropoda air tawar dan satu jenis cacing Trematoda, telur serkaria dan redia. Terjadinya perbedaan jumlah gastropoda air tawar disebabkan oleh beberapa faktor lingkungan yang mempengaruhi keanekaragaman gastropoda air tawar yaitu suhu, pH, kedalaman air dan substrat. Sedangkan adanya cacing Trematoda yang ditemukan pada gastropoda menyebabkan perbedaan prevalensi cacing Trematoda yang dipengaruhi oleh perbedaan jumlah cacing trematoda dan gastropoda air yang ditemukan serta kondisi lingkungan di masing-masing lokasi penelitian.

Abstract

Bats are the only mammals that can fly and belong to the order Chiroptera. Chiroptera consists of two suborders, namely Yangochiroptera and Yinpterochiroptera. This study aims to describe environmental factors and the diversity of bat species in the Cimaung Cave area. This research method is a quantitative descriptive research method with an exploratory approach, photo documentation, and data collection techniques using direct sweeping and a mist-net. The stations were used based on several existing zones, namely station 1 (Light Zone), station 2 (Dim Zone), and station 3 (Dark Zone). The results of research on bats found in Cimaung Cave belong to three families (Rhinolophidae, Hipposideridae, and Vespertlionidae) and four species (R. borneensis, R. affinis, H. larvatus, and M. australis). The results of the calculation of the ecological index of bats in the Cimaung cave area include the ShannonWeiner diversity index of 1.19 (moderate), the Krebs density index of 1.98 (very rare), the Simpson dominance index of 0.35 (moderate), the Krebs uniformity index of 0.86 (high) and the Magurran species richness index of 0.42 (low). Information on bat diversity in Cimaung Cave can be used as a basis for research development and utilization in the future. In addition, the presence of bat species in Cimaung Cave can also be used as a reference for education, conservation, and identification activities. As well as the utilization of the indirect economic value of bats, namely as plant pest controllers and guano providers as organic fertilizers.

Abstract

Presentation is one of the communication skills enabling the speakers to be able to think logically, accurately and firmly. This study was aimed at analyzing the students’ selfefficacy through their classroom presentations. The analysis was anchored on the empirical data obtained through observation results of 160 participants coming from the Biology Education Department, Siliwangi University, Tasikmalaya. In addition, the obtained data were analyzed and computed with descriptive statistical framework. The findings generally revealed that the students were accustomed to performing classroom presentations. This was supported by the evidence showing that the efficiency and effectiveness of classroom presentations were under 75% percentages of the total averages. Besides, the problem discussions were conducted with theoretical, practical, rationalistic and responsible attitudes, particularly under 75% percentages of the total averages. Also, the classroom presentations ran bi-directionally beyond 75% percentages of the total averages. Likewise, each member of presenters was actively engaged in classroom presentations with 75% percentages beyond the total averages. Additionally, the ability to present the materials attractively (e.g. videos, diagrams, pictures, etc.) was still under 75% percentages of the total averages. For these reasons, the students were accustomed to presenting the learning materials in the classrooms represented by their well-established presentation skills. However, a few skills should be taken into account through intensive trainings because they were still under the expected results.

Abstract

The way of life back to nature, including in the field of health, forms the habit of using plants as traditional medicine. Traditional medicine is indicated to be able to cure a variety of diseases. As with the leaves of Ciplukan (Physalis peruviana L.) by the people of Desa Wanasuka Kecamatan Pangalengan Kabupaten Bandung is considered to be used as a traditional medicine for inflammatory diseases such as rheumatism, asthma, and gastritis (maag) due to side effects and toxicity produced relatively small when compared with modern medicine. The aim of this study is to identify the potential of the secondary metabolite compound found in the leaves of the Ciplulan (Physalis peruviana L.) as a candidate for anti-inflammatory drugs. These research methods are molecular methods of docking through physical chemical properties testing, pharmacokinetic profiles of test compounds through site Pre-ADMET (Absorption, distribution, metabolism, excretion, and toxicity) and Lipinski Rule of Five. The results of this study showed that the binding affinity of caffeic acid compounds with PTGS2 receptors (PDB ID: 5F19) showed a more negative result compared to the comparative drugs Aspirin and Ibuprofen -7.4. There was a molecular interaction similar to Aspirin, in which the addition of amino acid residues from ASN 382 and TYR 385 produces a strong irreversible inhibition of PTGS2 (PDB ID: 5F19) and is predicted to inhibit prostaglandin H synthase and indicate that caffeic acid is capable of producing irreverible inactivation of PTGS2 (PDB ID:5F19). So potentially a candidate for a safer anti inflammatory drug for the body. Because it has almost the same or close potential as Aspirin against inflammatory diseases.

Abstract

Ketidakmampuan untuk menyelesaikan konflik, mengekspresikan diri kepada orang lain, dan merasakan empati terhadap teman sebaya di kelas dapat berdampak negatif pada tingkat keterlibatan siswa di kelas, dan hasil belajar secara keseluruhan. Penelitian ini merupakan penelitian korelasional yang bertujuan untuk mengetahui hubungan antara kecerdasan emosional dengan hasil belajar peserta didik pada materi sistem gerak manusia. Teknik pengumpulan data menggunakan non tes berupa kuesioner untuk kecerdasan emosional dan tes untuk hasil belajar. Responden penelitian adalah 34 peserta didik kelas XI MIPA SMA Negeri 1 Majenang, Jawa Tengah. Teknis analisis data menggunakan uji regresi korelasi bivariat dengan terlebih dahulu dilakukan uji prasyarat analisis berupa uji normalitas dan uji linearitas. Hasil penelitian menunjukkan ada hubungan kuat antara kecerdasan emosional dengan hasil belajar peserta didik. Kecerdasan emosional memberikan kontribusi sebesar 46,2% terhadap hasil belajar peserta didik pada materi sistem gerak manusia. Nilai koefisien regresi sebesar 0,334 dan nilai konstanta sebesar -7,637 menunjukkan bahwa apabila variabel bebas kecerdasan emosional dianggap tidak ada, maka nilai hasil belajar akan menurun atau buruk. Artinya, hasil belajar berhubungan dengan kecerdasan emosional sebagai variabel bebas, yaitu apabila kondisi kecerdasan emosional peserta didik buruk maka memungkinkan hasil belajar yang diperoleh peserta didik akan buruk juga. The inability to resolve conflicts, express oneself to others, and feel empathy for peers in the classroom can negatively impact the student's level of engagement in the classroom, and overall learning outcomes. This research was a correlational study that aimed to determine the relationship between emotional intelligence and students’ learning outcomes on human motion system material. The data collection techniques used the questionnaire for emotional intelligence and the test for learning outcome. The research respondents were 34 students of class XI MIPA at SMA Negeri 1 Majenang, Central Java. The data analysis technique used a bivariate correlation regression test with prerequisite analysis tests in the form of a normality test and a linearity test.The result showed that there was a strong relationship between emotional intelligence and students’learning outcomes.  The emotinal intelligence contributed 46.2% to students’ learning outcomes on human motion system material. The regression coefficient value was 0.334 and the constant value was -7.637 indicating that if the independent variable of emotional intelligence was considered absent, then the value of learning outcomes will decrease or be bad. That was, learning outcomes were related to emotional intelligence as an independent variable, so that if the condition of students' emotional intelligence was bad, it was possible that the learning outcomes obtained by students will also be bad.
