The use of technology in the process of learning activities can create a new atmosphere in biology learning, namely direct learning and learning using quipper school online. Learning like this is known as blended learning. The class used for the study was taken through cluster random sampling technique namely X MIPA 2 (experimental class) which implements blended learning and X MIPA 3 (control class) which implements a scientific approach. The implementation of blended learning on the topic of ecology is expected to be effective towards understanding concepts. Blended learning is effective on understanding concepts in ecological discussion because they fulfill three indicators, namely: (1) the average posttest of the experimental class 74.95> the mean posttest of the control class is 64.98, (2) The value of understanding the concepts to the two classes shows a significant difference with the values significance of 0,000<0,05, (3) Mean value of N-Gain experimental class 0.52> N-Gain mean value of control class 0.32. Thus, the implementation of blended learning in the ecology chapter in terms of understanding the concept is said to be effective.

AbstrakPendidikan pada bangku persekolahan terkadang tidak bisa diterima secara totalitas oleh semua peserta didik, dikarenakan peserta didik mempunyai gaya belajar masing-masing sehingga memunculkan sebuah permasalahan dalam proses pembelajarannya, khususnya seorang guru kadang dalam proses mengajar di kelas masih sering menggunakan media papan tulis dan metode ceramah hingga membuat peserta didik merasa bosan dan tidak mampu memahami materi yang disampaikan oleh gurunya. Penelitian ini bertujuan untuk mengembangkan media pembelajaran biologi berbasis PowToon yang valid, praktis, dan efektif. Penelitian ini mengadaptasi model pengembangan 4-D yang meliputi empat tahap yakni define (pendefenisian), design (perancangan), develop (pengembangan), dan disseminate (penyebaran). Berdasarkan hasil penelitian, diketahui tingkat kevalidan media pembelajaran biologi berbasis PowToon berada pada kategori sangat valid dengan nilai rerata sebesar 3,66. Tingkat kepraktisan media pembelajaran biologi berbasis PowToon berada pada kategori sangat praktis dengan nilai rerata sebesar 3,53. Hasil tes peserta didik dikategorikan sangat efektif karena mencapai rata-rata hasil belajar 83,54 dengan interval >80). Sehingga media pembelajaran biologi berbasis PowToon layak digunakan karena memenuhi tiga kriteria yakni kevalidan, kepraktisan serta keefektifan. Media pembelajaran biologi berbasis PowToon diharapkan dapat diimplementasikan pada kegiatan pembelajaran di kelas. AbstractEducation in school is sometimes not acceptable in totality by all learners, because learners have their own learning style so that it raises a problem in the learning process, especially a teacher sometimes in the process of teaching in the classroom still often uses whiteboard media and lecture methods to make learners feel bored and unable to capture the material delivered by their teachers. This research aims to develop a valid, practical, and effective PowToon-based biological learning medium. This research adapts the 4-D development model which includes four stages namely define (defining), design (design), develop dessiminate. Based on the results of the study, it is known the the level of validity of the PowToon based biology learning media is in the valid category and the mean value is 3.66. The level of practicality of the PowToon based biology learning media is in the very practical category with an average value of 3.53 student test results are categorized as very effective because they achieve an average learning outcome of 83.54 with intervals (>80). So that the PowToon based biology learning media is feasible to use because it meets three criteria, namely validity, practicality and effectiveness. PowToon based biology learning media is expected to be implemented in classroom learning activities.

Chemotherapy shows high effectiveness, but also has side effects, including mucositis. Mucositis can cause pain, difficulty sleeping, eating disorders, mood, and activity, which has implications for the quality of life of children. The purpose of this study was to identify the incidence of mucositis and the factors that influence the incidence of mucositis in cancerous children receiving chemotherapy treatment. This research method is descriptive correlational analysis with cross sectional design. Consecutive sampling technique was used to establish respondents as research samples so as to get 60 respondents. Data were analyzed univariately and bivariately. Bivariate analysis was performed with Chi square test and 2 mean difference test to see differences in the mean values of mucositis before and after chemotherapy. The results showed that almost all cancer children who received chemotherapy had 53 people (88.3%) and a small portion, 7 people (11.7%) had no mucositis. There was a significant difference in the mean value (p = 0,000) between before and after chemotherapy with an increase in the average mucositis value of 3.12. The research shows that there is a significant relationship (p <0.05) between previous mucositis experience (p = 0,000), type of cancer (p = 0.025), type of chemotherapy (p = 0.010), and duration of therapy (p = 0.027) and the incidence of mucositis. Meanwhile nutritional status was not related to the incidence of mucositis (p = 0.077). Nurses, as health workers who most often contact with patients, should be able to improve nursing care in cancer children who get chemotherapy in minimizing the occurrence of mucositis by conducting routine mucositis and oral care assessments.

Speaking is the ability to pronounce words in order to convey or stated intention, ideas, thoughsts, feeling and dificult to deal with students. There are some problems as causes of the students’ difficulties in speaking, such as they are afraid of making mistake, less convidence, seldom to communicate and cannot express their ideas. To solve the problems, the researcher suggests the use of PPP Model in learning process. Based on the previous explanation, the researcher formulates the objective of the research is to find out whether or not the speaking ability of the seventh grade students of SMP Negeri 9 Parepare can enhance through the Use of PPP Model In this research, the researcher applied quasi-experimental design, with two group namely experimental class and control class. The samples was chosen using cluster random sampling technique. The total numbers of sample were consisted of 55 students from two classes taken from the population of the seventh grade students of SMP Negeri 9 Parepare. The instrument used in this research was speaking test by record the students’ utterance. The data were analyzed by using t-test formula. The result of the data analyzed shows that the students’ speaking ability improved significantly. It was showed by the mean score of pre-test was 45.33 and the post-test was 72. 83. Besides, the mean score of the students in post-test (72.83) was higher than the Kriteria Ketuntasan Minimal (71) in SMP Negeri 9 Parepare and include good classification base on Dirjen Pendidikan Dasar dan Menegah (2005). In the same line, the result of t-test value was 2.102 and t-table value was 2.004 in post-test. It means that the t-test value (2.102) was higher than t-table value (2.004). Those indicate that H1 was accepted and H0 was rejected. It also shows there is a significant difference between the speaking ability of the students who were taught through the Use of PPP Model and the speaking ability of the students who were thought by Discovery Learning Model (Conventional Ways).

Background: Human Immunodeficiency Virus (HIV) / Acquired Immunodeficiency Syndrome (AIDS) has been a global problem nowadays. To reduce its spread, Voluntary Counseling and Testing (VCT) and Provider-Initiated Testing and Counseling (PITC) have been provided. However, these interventions remain ineffective to discover new cases, as the stigma among health officers may exist.Objective: To compare the stigma towards people living with HIV/AIDS between VCT and PITC officers.Methods: This was a descriptive comparative conducted in Makassar City, Parepare City and Sidenreng Rappang Regency, South Sulawesi Province Indonesia. There were 139 samples were selected using convenience sampling technique, which consisted of 66 VCT counseling officers and 73 PITC officers. The questionnaire from Health Policy Project in Thailand was used to measure the HIV/AIDS related-stigma. Data were analyzed using descriptive analysis and Mann Whitney test. Results: Findings show that there was a statistically significant difference in stigma between the group of VCT and PITC on people living with HIV/AIDS (PLWHA), which the mean of stigma in the PITC group (73.07) was higher than the mean value in the VCT group (66.61). Conclusion: There is a significant difference in stigma between VCT and PITC officers towards PLWHA. It is suggested that PITC curriculum should be evaluated and supervision and monitoring in both VCT and PITC groups should be implemented regularly to reduce the stigma towards PLWHA.

SummaryThe plasma tissue factor (TF) concentration was correlated to factor VII concentration (FVIIag) and factor VII activity (FVIIc) in 498 healthy volunteers ranging in age from 17 to 64 years. Immunoassays using monoclonal antibodies (mAbs) were developed for the determination of TF and FVIIag in plasma. The mAbs and the test systems were characterized. The mean value of the TF concentration was 172 ± 135 pg/ml. TF showed no age- and gender-related differences. For the total population, FVIIc, determined by a clotting test, was 110 ± 15% and the factor VIlag was 0.77 ± 0.19 μg/ml. FVII activity was significantly increased with age, whereas the concentration demonstrated no correlation to age in this population. FVII concentration is highly correlated with the activity as measured by clotting assay using rabbit thromboplastin. The ratio between FVIIc and FVIIag was not age-dependent, but demonstrated a significant difference between men and women. Between TF and FVII we could not detect a correlation.
