Abstract

The study aimed to observe the prevalence, intensity, and relationship of ectoparasites in bats in the southern region of Lombok Island, West Nusa Tenggara. The study was conducted in March 2018-February 2019. Bat samples were obtained from four caves in the southern part of Lombok Island. These caves include the Gale-gale Bangkang Cave, Buwun Cave, Semeti Cave, and the Raksasa Cave. Trapping bat samples for identification is done by using the Mist net. While taking ectoparasite samples is done by combing using a toothbrush. The organisms found were collected into sample bottles containing 70% alcohol. Analysis of the relationship between ectoparasites and bats was done by collecting data on ectoparasite species and ectoparasite abundance in each bat species, then further analysis was carried out to find the value of the Similarity Index (IS). The similarity index found is then cluster analysis. Cluster analysis aims to group based on similarity using Euclidean distance. The results of the study stated that based on the examination of 9 species of bats there were 14 species of ectoparasites identified. The value of the highest prevalence of ectoparasites in Gale-gale Cave Bangkang is found in Cyclopodia horsfieldii at 80% with an intensity value of 0.63, in Buwun cave is Amblyomma sp. of 100% with an intensity value of 1.50, in Cave Kenculit is Amblyomma sp. of 40% with an intensity value of 4.25 and in the Raksasa Cave is Cyclopodia horsfieldii of 70% with an intensity value of 0.71. While the relationship between the existence of ectoparasites in the bat's body states that the ectoparasite group in the body of bats can be grouped into 5 community groups. Group I consisted of the ectoparasite community in the Macroglossus minimus, and Rosettus an amplxicaudatus with Euclidean distance of 11,916. Group 2, the ectoparasite community was in Miniopterus pusillus, Rhinopoma microphyllum and Rhinolopus acuminatus with Euclidean distance of 15,362. Group 3 ectoparasite communities in the Chaerephon plicata and Taphozous melanopagon with Euclidean distances of 6,000. Group 4, the ectoparasite community only inhabited Eonycteris spelaea with Euclidean distance of 27,423. And group 5 also only inhabits Rhinolopus simplex with Euclidean distance of 46,293.

Abstract

This study aimed to describe student responses toward online learning. The respondents in this study were students of the first semester of the Biology Education Department in academic year 2019/2020, totaling 33 people. The sample in this study used a convenience sampling technique. The data obtained were analyzed descriptively using Microsoft Excel. Research data shows that only 6 percent of students feel happy with online learning, because respondents think that they are more flexible about the time and place of learning. Meanwhile, 91 percent of students stated that they were not happy due to many factors such as being difficult to meet face-to-face with friends and lecturers, requiring a lot of money to buy internet quota and an unstable internet network. Referring to these results, it is very necessary to conduct an evaluation by lecturers and relevant policy makers to support the achievement of maximum learning objectives.

Abstract

This study aimed to analyze the improvement of students' critical thinking skills in teaching inquiry with cognitive conflict strategies. Quasi experiments were conducted in this study. The research sample was twenty students as physics teacher candidates at a private university in West Nusa Tenggara - Indonesia. The critical thinking skills test instrument in the form of essay questions is used to measure students' critical thinking skills. The analysis of increasing of critical thinking skills was analyzed descriptively with the n-gain equation, and the difference in critical thinking skills between the pretest and posttest using a pair t-test which was preceded by homogeneity and normality tests. The results of the n-gain analysis showed that the increase in students' critical thinking scores was in the moderate category. Qualitatively, the increase in scores from pretest to posttest in a row is from not critically to enough critically. The results of this study imply that inquiry teaching with cognitive conflict strategies has the potential to be implemented in classroom teaching for the purpose of improving students' critical thinking skills.
