This study aims to see the effect of the gallery walk method application to the attitudes and activeness of the students. The research data was obtained through quasi-experimental research by using randomized subjects posttest only controlled group design. This research was conducted at VIII grade students of MTsS Darussalam Sitiung 1 Islamic Boarding School Dharmasraya Regency which consisted of 2 classes with a population of 50 students. Samples were selected by simple total sampling technique, where the experimental and the controlled class were selected by lotting method. Data collection was carried out using observation and data analysis techniques through statistical tests consisting of normality, homogeneity and hypothesis tests with a significance level of 5%. Data from the hypothesis using the t test shows that the tcounted for the formation of attitudes, and activeness is 3.21 and 2.16, respectively with v = 48. Based on these values it is known that tcounted> ttable for the attitudes and activeness of students, namely (3.21> 1.677), and ( 2.16> 1,677) at the 5% significance level. Thus the hypothesis Ho is rejected and H1 is accepted, where the formation of the attitudes and activeness of students using the gallery walk method is better than using conventional learning with a certainty of 95%.

Differential equations are one of the topics in mathematics that have many applications in mathematical modeling, for example in population growth. Population growth is an important thing that needs to be considered in order to be able to see the development of an area so that it can assist the regional government in determining the policies taken for the progress of the region related to the potential growth of the existing population. In this paper we will study population growth models with limited growth. From this model, the population of a region can be predicted in the coming year

Infant growth is largely determined by the amount of breast milk obtained including the energy and other nutrients contained in breast milk. Breastfeeding in Indonesia has decreased, especially in West Sumatra based on Indonesia Health Profile in 2014. This study aims to determine the Influence of Exclusive Breastfeeding on the growth and development of infants aged 6-24 months in Nagari Sariak Laweh Working Area Batu Hampar Puskesmas, District Akabiluru. The measured growth consists of body weight, body length and Head Circumference. Progress was seen through KPSP (Pre-Growth Questionnaire Developments). This type of research is an observational research that is analytic with Cross-Sectional research design. Data analysis used was univariate and bivariate (Independent T test). The study period was from October 2017-February 2018. The population in the study were infants aged 6-24 months in Nagari Sariak Laweh. The sample in this study amounted to 30 babies. Data collection was done by using questionnaire and direct measurement. The statistical results show that there is no Influence of Exclusive Breastfeeding on Infant Growth (body weight, body length, head circumference) and no Influence of Exclusive Breast Feeding on Infant Development (based on KPSP questionnaire).

ANALISA KUALITATIF DAN KUANTITATIF KANDUNGAN ALKOHOL PADA TAPAI KETAN DI KOTA BATUSANGKAR Sari, Maya; Fajar, Najmiatul

The black sticky tapai/ Tapai ketan hitam in Batusangkar, made by fermentating black sticky rice and yeast. The fermentation of black sticky tapai take several days to produce a sweet taste. This process may some assumption that the sweetness in black sticky tapai comes from alcohol as a result of sticky rice fermentation reaction with yeast. As the time of fermentation increases alcohol content, this raises doubt the halalness of black sticky tapai, because based on MUI Fatwa Number.4 in 2003 says the drinks containing ethanol (C2H5OH) more than one persen are categorized haram. Because of that, need some research to see the impact of duration fermentation to alcohol concentration on black sticky tapai in Batusangkar city. The reaserch data was obtained by distillation from various duration of fermentation. The result data were analyzed by product moment correlation test (? = 5%). Base on the research conducted, obtained information that in black sticky tapai contain etanol which has increased alcohol concentration along with the increase of fermentation duration. However, it becomes contradictory with the result of analysis where Y = 3,635 - 15,54 X, t arithmetic ? t table, that is 0,16 ? 3,18. This conclusions that there is no relationship between duration of fermentation with alcohol concentration.

As a heavy polluted river in Yogyakarta, Gajah Wong River has been the target of Environment Agency (BLH) for its protection and water treatment program. Our preliminary research shows it had DO 0 mg/L, BOD 27, 86 mg/L, COD 79, 49 mg/L, Pb 0,03 mg/L and PO4 3,250 mg/L. The aim of this research was exploring the effectiveness of water treatment system using carbon nano tube based on coconut shells activated carbon integrated with wetland system. The Carbon nano tube was synthesized by using CVD methods while wetland system contains plants (which absorb pollutants. The result of this research are participated from Gajah Wong community and the water become more purify signed by BOD, DO, PO4 and COD normal value.
