Abstract

ABSTRAKTujuan dari penelitian ini adalah untuk mengidentifikasi miskonsepsi siswa dengan analisis menggambar. Tiga puluh empat siswa di kelas 8 di sekolah menengah pertama digunakan sebagai subyek dalam penelitian ini. Teknik sampel menggunakan teknik purposive sampling. Data yang diperlukan untuk penelitian ini dikumpulkan melalui kuesioner, menggambar analisis rubrik, dan wawancara. Identifikasi Kesalahpahaman ditentukan dengan menggambar siswa berdasarkan menggambar kriteria klasifikasi oleh Kose (2008). Siswa diperintahkan untuk menarik tentang konsep fotosintesis setelah proses pembelajaran. Gambar siswa dianalisis dengan rubrik dan setelah itu mereka diwawancarai. Hasil penelitian menunjukkan tidak semua tingkat kriteria menggambar dari tingkat 1 sampai 5 diidentifikasi. Dari hasil analisa, gambar paling banyak ditemukan adalah pada tingkat 4. Gambar pada tingkat 4 dikategorikan sebagai gambar lengkap konsep fotosintesis dan tidak ada kesalahpahaman ditemukan. Berdasarkan gambar mereka, ada siswa 2,9% diidentifikasi yang diselenggarakan kesalahpahaman. Ada perbedaan jumlah siswa yang diadakan kesalahpahaman antara gambar hasil analisis dan hasil wawancara. Dari hasil wawancara, ada siswa 35,2% dimiliki kesalahpahaman, lebih dari menggambar hasil analisis. Ini berarti bahwa identifikasi kesalahpahaman melalui analisis gambar tidak efektif. Kesalahpahaman siswa yang paling sering terjadi pada konsep fotosintesis adalah tempat berlangsungnya fotosintesis. Faktor yang membuat kesalahpahaman siswa yaitu karena siswa itu sendiri dan lingkungannya.ABSTRACTThe aim of this study was to identify students’ misconception by drawing analysis. Thirty-four students on 8th grade at junior high school were used as subject in this study. The sample technique was used purposive sampling technique. Data required for this study were collected through questionnaire, drawing analysis rubric, and interview. Misconception identification was determined by students’ drawing based on drawing classification criteria by Kose. Students were ordered to draw about photosynthesis concept after learning process. Students’ drawings were analyzed by rubric and after that they were interviewed. The result showed not all criteria level of drawing from 1st level until 5th was identified. From the analysis result, the drawing most found was on 4th level. The drawing on 4th level was categorized as incomplete drawing of photosynthesis concept and no misconception found. Based on their drawing, there were 2,9% students identified which held misconception. There was difference amount of students which held misconception between drawings analysis result and interview result. From the interview result, there were 35,2% students held a misconception, more than drawing analysis result. It means that identification misconception through drawing analysis was not effective. The most students’ misconception on photosynthesis concept was the location of photosynthesis occurred. Factor that made students’ misconception because students’ itself and their environment.

Abstract

This study was conducted to determine the physiological response of acute heat stress in Kampung Unggul Balitbangtan (KUB) and Walik chickens with four different HSP70 gene haplotypes (H1', H1, H2, and H3). Acute heat stress is carried out at 35°C for one hour. The data was analyzed based on rectal temperature measurements, distribution of body surface temperature (head, neck, body, and leg area), hormone levels (corticosterone and triiodothyronine), and time of panting. Body surface temperature is detected using infrared thermography. The results showed that haplotype H1 Walik chicken is more susceptible to heat stress based on the rectal temperature. In contrast, H1' haplotype Walik chicken released more heat through the body surface in the leg area. Keywords: heat stress, hormone, KUB chicken, infrared thermography, walik chicken

Abstract

This study aims to determine the effect of the Argument-Driven Inquiry (ADI) learning model application on the concepts mastery and argumentation skills of high school students on reproductive system material. The research method used quasi-experimental and non-equivalent control group design. The sample of this research were second-grade high school MIPA students in one of the public high schools in Bandung, which consists of 30 students in the experimental class and 33 students in the control class. The sample was taken by using the purposive sampling technique. The instruments used consisted of a concept mastery test in the form of multiple choices, an argumentation ability test in the form of an essay, and questionnaire of students’ responses to the ADI model. The results showed that the application of the ADI learning model significantly affected the students' concepts mastery on reproductive system material in the experimental class compared to the control class, especially in the cognitive aspects of C3 (applying). The results also show that the application of the ADI learning model significantly affects the ability of argumentation, especially on the warrant component. Student response data shows that students respond very well to the application of the ADI learning model. Therefore, the ADI learning model is recommended for biology teachers to improve students’ concepts mastery mastery and argumentation skills in other biological materials.

Abstract

Our research was designed to identify the sequence variations of heat shock protein 70 (HSP70) gene in three breeds of native Indonesian chickens, Kampung Unggul Balitbangtan (KUB) chicken, Walik chicken, and Kate Walik chicken. Total DNA was isolated from the whole blood using a DNeasy blood and tissue kit. The HSP70 gene was amplified and sequenced from 94 chickens using PCR. The amplification product was 787 bp long, consisting of a 210 bp promoter region, a 112 bp long 5′untranslated region (UTR), and a 465 bp protein coding region. Our KUB, Walik, and Kate Walik chicken HSP70 gene sequence alignments express genetic diversity in the promoter region (insertions and deletions), 5′UTR (deletions and nucleotide substitutions), and at the beginning of the coding region (nucleotide substitutions). Four haplotypes, H1, H2, H3, and H4, were identified in the HSP70 gene protein coding region. The haplotype H2 was found in all three chickens, while H4 was only found in Walik chicken. The H4 is a novel haplotype which never reported before. Based on a median-joining network analysis, H4 is a haplotype produced by mutations at two specific sites (g.370A>G and g.388C>G) in the protein coding region of the HSP70 gene of the chicken. It could be concluded that Walik chicken can be used as a standard for heat stress genotyping in Indonesian local chickens, because it has complete HSP70 gene haplotypes.

Abstract

This study aims to analyze the classification ability in animal biosystematics learning as the basis for making numerical taxonomies in biology education students. The method in this research consists of qualitative and quantitative analysis. Descriptive method is used for qualitative analysis and correlation method for quantitative analysis. The mixed methods strategy uses simultaneous triangulation because both qualitative and quantitative data are collected at the same time, then compared to identify convergence of differences or combinations of data. The number of students was 57 people who were divided into 11 groups. Ability classification is determined based on indicators that refer to science process skills. The classification ability indicator is made into six indicators, where each indicator is broken down into four sub indicators. The results of the analysis show that the classification abilities of the six indicators are: (1) recording each observation separately 89.04%, (2) looking for similarities and differences of 66.23%, (3) contrasting the features of 57.89%, (4) comparing of group characteristics 67.32%, (5) determining the basis for grouping 73.46%, and (6) connecting the results of observations 76.32%. The ability of individuals to make classifications in animal biosystematic learning reached 71.72%, while in groups it was 71.98%. Based on the results above, it can be concluded that the classification ability of participants in animal biosystematic learning is good with the medium category, this can support in making numerical taxonomy.
