Penelitian bertujuan mengetahui populasi dan pola sebaran burung-burung yang terdapat di kawasan Galunggung periode pemulihan pasca 31 tahun meletus.Metode point count jarak tidak tetap digunakan dalam penelitian ini Gunung Galunggung telah ditetapkan sebagai kawasan Wanawisata Galunggung sejak tahun. Penelitian dilakukan dengan membagi dalam 5 blok pengamatan. Sejumlah 80 titik penghitungan burung ditetapkan dalam 0,7222 km2 luasan area. Berdasarkan hasil penelitian dijumpai 39 spesies burung dengan total 719 individu. Ada 10 spesies burung ditemukan dengan populasi tinggi, yaitu Cynniris jugularis (96,93 ind/km2), Lonchura leucogastroides (84,46 ind/km2), Orthotomus sutorius (70,61 ind/km2), Orthotomus cucullatus (62,30 ind/km2), Zosterops palpebrosus (67,85 ind/km2), Pycnonotus aurigaster (55,39 ind/km2), Brachypteryx leucophrys (41,54 ind/km2), Stachyris melanothorax (38,77 ind/km2), Streptopelia chinensis (30,46 ind/km2), dan Halcyon cyanoventris (26,30 ind/km2). Nilai indeks Morista sebesar 7,67, ini menunjukkan bahwa pola sebaran dari sebagian besar burung di Wanawisata Galunggung adalah mengelompok. Secara spesifik tercatat 1 spesies burung sebaran terbatas (Stachyris melanothorax), 1 spesies burung migran (Motacilla cinerea), dan beberapa spesies burung endemik dan dilindungi.When the Galunggung mountain erupted in 1982, most of Galunggungs flora and fauna were devastated severely. A research has been carried out to know about bird population and their dispersion patterns in the Galunggung Tourism Forest after 31 years of restoration phase. The research used nonfixed distance Point Count method and this research was conducted by dividing the observation area into 5 blocks. Eighty watchout points have been established in an area of 0.7222 km2. The study revealed 39 bird species with total of 719 individuals. Among them, 10 species had relatively high population, i.e. Cynniris jugularis (96.93 inds/km2), Lonchura leucogastroides (84.46 inds/km2), Orthotomus sutorius (70.61 inds/km2), Orthotomus cucullatus (62.30 inds/km2), Zosterops palpebrosus (67.85 inds/km2), Pycnonotus aurigaster (55.39 inds/km2), Brachypteryx leucophrys (41.54 inds/km2), Stachyris melanothorax (38.77 inds/km2), Streptopelia chinensis (30.46 inds/km2), and Halcyon cyanoventris (26.30 inds/km2). The Morisita index was 7.67, which indicates that some bird species flocked in groups. The range of Stachyris melanothorax was restricted, whereas Motacillacinerea is considered as migrant species, and others were endemics and protected birds.

Abstract

Scientific literacy is very important to generation Z (Gen-Z), while Gen-z’s scientific literacy in Indonesia needs to be improved. The use of gadgets by Gen-Z almost all the time in their daily lives enables research to improve scientific literacy by using gadgets. This study aims to determine the effectiveness of gadget-based interactive multimedia to improve Gen-Z scientific literacy and describe the Gen-Z response to interactive multimedia. This research was a pre-experiment study with one group pretest and posttest design. Interactive multimedia was designed to be applied on gadget, consists of Socioscientific Issues (SSI) which was relevant to pressure concepts. This research involved two junior high schools in East Java, Indonesia. Scientific literacy test instrument was designed based on scientific literacy aspects of PISA 2015. The inferential test results showed that posttest score was significantly greater than the pretest in the two schools. Results showed that the mean score of students’ scientific literacy at School I increased from 39.6 to 74.0 and N-gain score was 0.57 which was in medium category. In addition, the average scientific literacy score of students in School II also increased from 31.5 to 59.9 and Ngain score was 0.41 which was in the medium category. The inferential test results also showed that there were no significant N-gain differences in the two schools. It can be concluded that interactive multimedia developed effective to improve students’ scientific literacy. However, Gen-Z students cannot be satisfied with the multimedia. Students suggest several multimedia enhancements in terms of visual, audio, and music, so that they can enjoy the multimedia all the time by using the device.

Abstract

Gene markers are often usefull for selection process of cattle on commercial certain phenotypes. Saanen goat has predominance in milk production traits. Milk fat content is one of the commercial traits of milk production. Diacylglycerol Acyltransferase1 (DGAT1) gene was involved in the final process of triglyceride synthesis and associated with milk fat content. Single nucleotide subtitution or insertion-deletion in certain sequence of DGAT1 gene could be gene markers for milk fat content. The objective of this study was to identify differences variation in milk fat content among individual Saanen goats, to identify exon 14-16 polymorphism of DGAT1 gene and to examine its correlation between polymorphism and milk fat content on Saanen goats. The methodologies was collection blood and milk samples, DNA isolation from blood, amplification of DGAT1 genes, sequencing, detection of polymorphism of exon 14-16 DGAT1 gene with Polymerase Chain Reaction-Single Strand Conformation Polymorphism (PCR-SSCP), and examination milk quality on three lactation months using Lactoscan. The average of daily milk production from 70 Saanen goat was 2340±709 mL, 1880±632 mL, 1432±536 mL and average of milk fat content was 3.07±0.52%, 2.53±0.55%, 3.00±0.55% for the first, second and third months of lactation, respectively. The amplicon size of exon 14-16 of DGAT1 gene was ± 350 bp and showed monomorphic pattern from PCR-SSCP. Variation of milk fat content on Saanen goats not caused by polymorphism of exon 14-16 DGAT1 gene.

Abstract

This research aims to examine undergraduate students’ argumentation skills during and after the learning process in the classroom setting and their responses toward the implementation of socioscientific issues (SSI) through debate in the learning process. This research involved 32 undergraduate students and implemented design-based research with pretest and posttest in a natural classroom setting using three topics of SSI debate that widely discussed in Indonesia: Nuclear Powerplant (Topic 1), Food Preservation (Topic 2), and Genetically Modified Organism (Topic 3). Data was collected using observation sheets, tests, and questionnaires. Observation is to measure argumentation ability when applying the debate method in class settings, the test measures the improvement of argumentation skills, and questionnaires measure students’ responses to the application of the debate method. In this study, argumentation scores were obtained from six indicators and divided by a maximum score of 24 times 100. Normalized gain (N-gain) was calculated to determine the effectiveness of the intervention in the classroom. T-test was also conducted to test the significance of the differences in the pretest and posttest results on argumentation skills.  The results obtained in this study are: the argumentation skills score during the learning process for six groups were 95, 80.6, 90.3, 95, 83.3, and 77.5; the mean score of pretest and posttest were 52.22 ± 6.62 and 85.78 ± 4.72. The consistency of opinions shows the change from “agree” to “disagree” for Topics 1 and 3. The undergraduate students agree and consistently agree toward Topic 2. The paired t-test result also shows that the intervention statistically has a significant difference between the two means, indicating that the undergraduate students’ argumentation skills are better than before the intervention. Otherwise, most of the undergraduate students respond positively toward the implementation of the debate related to SSI. Despite some limitations, the debate on SSI can improve argumentation skills in classroom settings, especially in science education majors.

Abstract

Significant and unexpected changes need to be anticipated by all teachers, especially when facing difficult situations in the learning process. This study aims to determine the mediating role of attitude in the correlation between creativity and curiosity regarding the performance of outstanding science teachers. A quantitative causal method was used which involves 100 teachers that were selected using a purposive sampling technique. Collection of research data using four questionnaire instruments with a Likert-scaled were derived from the existing grand theory and met the psychometric properties as a suitable instrument to use. Multiple regression analysis is used to identify the relationship between these variables. The results of the data analysis showed that the creativity affects attitude directly and attitude also affects performance. Other results show that curiosity has a direct effect on performance and has no indirect effect on performance. Meanwhile, other results also explained that the investigated variables are positively correlated with the outstanding science teachers. The results of the study concluded that attitude can act as an effective mediator in the relationship between creativity and performance. Creativity and curiosity are important variables to support the performance of outstanding science teachers. The limitations of this study and discussions were subsequently explained in this article.
