Effectiveness of guided inquiry-based module to improve science process skills

Abstract: Science process skills (SPS) are important in science learning. SPS is a skill process that encourages lifelong learning. In guided inquiry-based science learning, students engage in many of the activities and thought processes that scientists use to generate new knowledge. This inquiry approach can be implemented effectively with the use of chemistry modules for investigation in which students learn to understand the content of the subject. This study examines the effectiveness of guided inquiry-based modules for SPS. The study participants were 63 students in 11th graders. Data were collected through the test. Quantitative analysis is done to know the SPS of student. The test result shows that the n-gain of SPS students in the treatment class has a better percentage of categories than the control class. The effect size (ES) also shows a value of 0.51 which is moderate category. The achievement of indicator SPS in the treatment class is also better than the control class.

Pembelajaran ipa menggunakan pendekatan inkuiri terbimbing melalui metode eksperimen dan demonstrasi ditinjau dari kemampuan analisis dan sikap ilmiah siswa

Abstract: The aims of the research were to know the effect among guided inquiry approach through experiment and demonstration methods, analytical skill, and scientific attitude and their interaction toward students’ achievement in science. The research used quasi experimental method. The sample was taken using cluster random sampling consisted of 2 classes, VIIIB as experiment learnt by experiment method and VIIID as experiment II learnt by demonstration method. The data was collected using test for cognitive achievement and analytical skill, questionnaire for scientific attitude and affective achievement, and observation sheet for affective achievement. The data was analyzed using Anova with 2X2X2 factor design and continued using Scheffe’ calculated by PASW 18. The result showed that: (1) there was no effect of guided inquiry usage through experiment and demonstration method toward students’ achievement; (2) there was no effect of high and low of analytical skill toward students’ achievement; (3) there was effect of high and low of scientific attitudes toward students achievement; (4) there was no interaction between guided inquiry usage through experiment and demonstration method and analytical skill toward students’ achievement; (5) there was interaction between guided inquiry usage through experiment and demonstration approach and scientific attitude toward students’ achievement affective domain but there was no effectin cognitive one; (6) there was no interaction between analytical skill and scientific attitude toward students’ achievement; (7) there was no interaction among guided inquiry approach through experimentand demonstration methods, analytical skill, and scientific attitude toward students’ achievement. Keywords: guided inquiry, experiment, demonstration, analytical skill, scientific attitude

Semantic mapping relational to graph model

Abstract: Making data to be more connected is one of the goals of Semantic Technology. Therefore, relational data model as one of important data resource type, is needed to be mapped and converted to graph model. In this paper we focus in mapping and converting without semantically loss, by considering semantic abstraction of the real world, which has been ignored in some previous researches. As a graph schema model, it can be implemented in graph database or linked data in RDF/OWL format. This approach studies that relationship should be paid more attention in mapping and converting because, often be found a gap semantic abstraction during those processes. In our small experiment shows that our idea can map and convert relational model to graph model without semantically loss.

Karakterisasi senyawa bioaktif isoflavon dan uji aktivitas antioksidan dari ekstrak etanol tempe berbahan baku koro pedang (Canavalia ensiformis)

Abstract: The objectives of the research were to find out: (1) the contents of the isoflavone compounds of daidzein,genistein, glisitein, and factor-2, and (2) the antioxidant activity of jack bean andits tempeh product. The material used for the researchwas jack bean with the treatment of the whole and choppedseed size and length of fermentation (0,1,2, 3,4 days) compared with the ethanol extract of the soy bean and its tempeh product and several natural antioxidants (α-tocoferol, s carotene, and Vitamin C) and BHT synthetic antioxidant. The method used to extract the isoflavone compounds was maceration, and the method used toidentify the isoflavone compounds was that of HPLC. The test of antioxidant activity used the method ofDPPH. Theanalysis of the data of the test of antioxidant activity used the methodof GeneralLinear Model – Univariate and Compare Means – One-Way Anova. The largesttotal content of the isoflavone compounds of the tempeh made of the whole and chopped jack bean tookplace in the 1-day fermentation, that is,0.786% and 0.590% whilethe largesttotal content of the isoflavone compounds of the tempeh madeof the soy bean took place inthe 2-day fermentation, that is, 1.812%. The highest antioxidant activity of the tempeh made of thewhole and chopped jack bean and soy bean took place in the 3-day fermentation, that is, 77.32%, 68.63%, and 81.43% respectively. Theantioxidant activity of the tempeh made of the soy bean was relatively similar to that of of BHT, that is,at the range of 81%, and the antioxidant activityof the tempeh made of the wholejack bean was relatively similar to those of vitamin C and α-tocoferol, that is, ranging from 75% to 77%. The oxidant activity of the tempeh made of the chopped jack bean was lower compared to those of soy bean, natural antioxidant (Vitamin C and α-tocoferol and BHT) significantly different that is 69%, and s carotene (45%) had the lowest antioxidant activity.

The Associations between Exclusive Breastfeeding, Complementary Feeding, and the Risk of Stunting in Children Under Five Years of Age: A Path Analysis Evidence from Jombang East Java

Abstract: Background : Stunting in children becomes a health problem that gets priority and must be addressed immediately. Delayed development, a decrease in cognitive function and immune function and the risk of diabetes mellitus, coronary heart disease, hypertension, and obesity are the effects of stunting. This study aimed to analyze the determinants of stunting in children aged 2-3 years in Jombang, East Java. Subje cts an d Met hod : This was an analytic observational study with case-control design. The study was carried out at Plandaan and Kabuh community health centers, Jombang, East Java, from March to April 2019. A sample of 200 children aged 2-3 years old was selected by fixed disease sampling. The dependent variable was stunting. The independent variables were maternal age, maternal height, maternal attitudes, maternal occupation, birth length, infant birth weight, exclusive breastfeeding, breastfeeding, family income, mother's education, and mother's know­ledge. The data collection was done using questionnaires and analyzed with path analysis. Results : Stunting was directly and negatively affected by birth length ≥ 48 cm (b= -2.37; 95% CI= -3.25 to -1.50; p 150 cm, employed mother, maternal education, and maternal knowledge. Conclusion : Stunting is directly and negatively affected by birth length of ≥48 cm, birth weight ≥ 2500 g, exclusive breastfeeding, timely complementary feeding. It was indirectly affected by family income, maternal age, attitude, maternal height >150 cm, employment, education, and knowledge.
