Effectiveness of the development of the inquiry-based learning model to improve students’ psychomotor achievement

Students often consider chemistry as a difficult subject. Therefore, an engaging learning model is important in chemistry learning. This study aimed to produce an effective learning model to improve students’ psychomotor achievement. This study used research and development using ADDIE model. The research was conducted in two senior high schools in Padang Sidempuan, North Sumatera. The participants were divided into an experimental class and a control class. The effectiveness of the learning model was investigated by assessing students’ learning achievement, especially on the psychomotor aspect. The result showed that the inquiry-based learning model was effective. This result implies that the model can be used to improve students’ psychomotor achievement.

Stress heterogeneity and its impact on seismicity pattern along the equatorial bifurcation zone of the Great Sumatran Fault, Indonesia

A stress transfer modeling revealed the stress heterogeneity and its correlation with the seismicity pattern in the bifurcation zone of the Great Sumatran Fault (GSF), where the GSF is divided into two separate sub-parallel segments up to 35 km apart, i.e. Angkola and Barumun, forming a strike-slip duplex at around equator. The analysis was conducted using a seismic catalog compiled from five institutions, i.e. the Indonesian Agency for Meteorology, Climatology, and Geophysics (BMKG), United States Geological Survey USGS), Harvard and Global Centroid Moment Tensor (GCMT), International Seismological Center (ISC), and Geoforschungzentrum (GFZ) Germany, in the period of 1970–2017. Our frequency-magnitude distribution analysis indicates that this zone has a high stress regime. Especially at the tip of the bifurcation zone, in which 20° clockwise rotation of principal stress and 20% increase in stress ratio are observed from the stress inversion. Consequently, events with magnitude larger than 6.0 are concentrated in this area. In addition, our stress transfer modeling reveals the mechanism of the stress heterogeneity at the bifurcation zone and a possible interaction between segment ruptures. Two main internal structures perpendicular to the strike-slip duplex are also observed from the displacement vector. Due to its high stress concentration and its close distance to populous cities of Padang Sidempuan, Bukittinggi, Solok and Padang Panjang in western Sumatra, the tip of GSF bifurcation poses a big potential of seismic hazard. The information of the principal stress rotation and stress ratio obtained in this study can be used further to assess the potential of great ruptures and estimate the possible damage in the study area.

Workshop GURAME "Guru Asyik Menyenangkan/Fun Teachers" at Darul Hasan Padang Sidhuan School

Teachers are the spearhead of educational success. Learning will be enhanced if the teacher is able to provide fun learning and meaningful activities. However, to be a fun teacher is not an easy task to create and implement. There are so many issues that often emerge, one of them is the inability of teachers to detect learning modality as the first step in determining the appropriate learning strategies in the classroom. This misunderstanding ultimately leads to uniform learning that causes problems in learning. In addition, the lack of understanding and use of ice breaking as one way to break the ice in the class and selection of ice breaking activities in accordance with teaching materials is worth contributing. Thus, these two things are still very necessary to understand in managing the class because thesetwo things lead to pedagogic competence that must be owned by teachers according to Law no 4 of 2005. Able to understand learners, designing learning and evaluating learning outcomes. The purpose of this Workshop activity is (1) the teacher is able to detect learning modality to jump-start learners' learning potential (2) Teachers are able to master ice breaking as a trick to create a fun class. Because mastering these two things will help teachers in creating and managing the class become fun. This devotion was held at Darul Hasan Foundation in Padang Sidempuan City, followed by 50 teachers. The result of the GURAME workshop is that the participants have been able to detect learning modality, understand the application of ice breaking in the classroom as well as motivated to keep learning to be fun

Peramalan Indeks Harga Konsumen dengan Metode Singular Spectral Analysis (SSA) dan Seasonal Autoregressive Integrated Moving Average (SARIMA)

Consumer Price Index (CPI) are the indicators used to measure the inflation and deflation of a group of goods and services in general. Forecasting CPI to be important as early detection in facing price hikes. This study uses the SSA and SARIMA. SARIMA a parametric model that requires various assumptions while SSA is a nonparametric technique that is free from a variety of assumptions, but both methods require seasonal patterns in the data. Based on the research results, methods of SSA with length window(L) of 24 and a grouping of 4 (1 group of seasonal and 3 groups of trends) and SARIMA models of order (0,1,1), (0,1,1) 6 is the most accurate and reliable models in forecasting CPI to the value Padang Sidempuan City. Forecasting CPI Padang Sidempuan City for the next 5 months with SSA method and SARIMA (0,1,1), (0,1,1) 6 shows the pattern of a trend is likely to increase but forecasting the 5th month with SSA method showed a surge in the value of CPI high or high inflation will occur.

MODEL PENDEKATAN ALAT UJI KEPADATAN RINGAN UNTUK TANAH DI LABORATORIUM (PENELITIAN LANJUTAN I)

The study, entitled "the application of the Model as a means of Testing the density of light to the ground in the lab (Advanced Studies 1)". Backed by research from previous research, entitled "the application of the Model as a means of Testing the density of light for the soil in the laboratory", in previous studies of soil clays used example is the land of clays from the village of Baringan, the city of Palangkaraya. While soil samples in this study used is the land of the village of Palopat Sub-district of Padang Sidempuan PK, Southeast, or rather in the STA 500 Padang Sidempuan 4 heading Mandailing Natal. This study aimed 
 to compare the CBR and UCS clay stabilized sand and cement for the pavement. The research aims to conduct an analysis of the maximum density of soil clays based on Models by as much as 33 collisions per layer as much as 2 layers obtained the maximum dry weight (?d max) and optimum moisture content (w opt) and SNI 1742:2008. If the level of the margin of error is obtained and has 5% < assessment of performance against the same heap, then the Model can be used as a means of testing the density of light to the ground in a lab that has the same standard with SNI 1742:2008.

Placenta previa, anemia, care in antenatal, employment score: Development of a scoring system to predict low birth weight in underserved area in Indonesia

Background: Early intervention of low birth weight (LBW) should reduce maternal and fetal morbidity. In underserved areas, with inadequacy of health technologies, it was very important to develop a simple scoring system based on the LBW risk factors. Aims and Objective: The aim of this study is to develop a scoring system to predict LBW in underserved area. Materials and Methods: This case–control study enrolled total of women with a singleton LBW in Padang Sidempuan General Hospital. For every case, the subsequent woman who delivered a baby weighing ≥2500 g acted as control. All data were by Chi-square or Fisher’s exact test. Significant variables were taken to be analyzed in backward stepwise binary regression. Then, receiver operating characteristic curve was developed to determine cutoff point and diagnostic value. This was done by SPSS (Statistical Product and Service Solutions, Chicago, IL, USA) 22.0 with 95% confidence interval significant value. Results: This study involved 62 LBW and 62 normal birth weight newborns. Among all variables, only four variables were found to be significant, such as employment, antenatal care, history of anemia in pregnancy, and history of placenta previa in pregnancy. The placenta previa, anemia, care in antenatal, employment (PACE) score was obtained as score for employment was +1, antenatal care was −2, history of anemia in pregnancy was +2, and history of placenta previa was +3. The cutoff point was determined as 0, where a positive score will predict fetal with LBW and total score ≤0 (negative) will predict fetal with normal weight. This model had sensitivity of 88.7%, specificity of 66.1%, and area under curve 0.844 (P < 0.001). Conclusion: Positive total score of PACE could be a promising predictor for LBW in underserved area.
