Abstract

Saponins are secondary plant metabolites binding hydrophobic non-sugar components that can reduce ruminant methane (CH4) production. Previous studies revealed that tea saponin is one of the common sources of saponins used to reduce enteric CH4 production. However, the effect of different levels of dietary tea saponin on rumen fermentation remains inconclusive. This study aimed to investigate the effect of tea saponin on in vitro rumen fermentation and methane production through a meta-analysis approach. A total of 6 articles were selected and included in the meta-analysis database, continued by the statistical analysis using SAS software through mixed model formula. The results showed that tea saponin levels lowered in vitro organic matter degradability (IVOMD) and in vitro dried matter degradability (IVDMD; P=0.01) by a linear response. Furthermore, increased tea saponin levels in the diet reduced enteric CH4 emission expressed as CH4/DM substrate and CH4/IVOMD by a quadratic (P=0.01) and a linear response (P=0.04), respectively. Increased tea saponin levels also tended to decrease gas production linearly (P=0.08). Tea saponins inclusion also decreased pH levels linearly (P=0.04) but increased NH3 quadratically (P=0.01). Moreover, total VFA concentration in the rumen also raised quadratically, followed by the increased acetate (C2) and propionate (C3) proportion by a linear response (P<0.05). As a result, the C2/C3 ratio was decreased in a linear response (P=0.01) by the increased tea saponin levels, where the protozoa population was also diminished by a quadratic response (P=0.01). In conclusion, tea saponin levels directly reduced enteric CH4 production by diminishing microbial populations.

Abstract

This study has a goal, namely to describe the attitudes of junior high school students towards learning Mathematics. Disclosure of students' attitudes in learning mathematics is based on low mathematics learning outcomes at the junior high school level in Siak and Rokan Hulu Regencies, Riau Province. The type of research used is evaluation. The sample for this research was obtained from some students who were in Siak and Rokan Hulu Regencies, Riau Province. By using a sampling technique in the form of random sampling and data collection techniques in the form of surveys. The instrument used in this study was a questionnaire, to measure junior high school students' attitudes towards learning mathematics. Before the instrument was used, the instrument in the form of a questionnaire was validated in terms of content and construct. In terms of content, validity analysis used the aiken formula while construct validity used second order CFA. Statistical analysis by calculating the average and standard deviation and consulting the assessment guide table to obtain an assessment of individual student attitudes. The evaluation results show that the attitude of SMP towards learning mathematics is in the category of good students. Keywords: Attitude analysis, mathematics learning, junior high school

Abstract

This study aims to develop an instrument to evaluate Indonesia’s children-friendly school program (CFSP). This development research is then used to evaluate CFSP in Indonesia. Instrument development using the context, input, process, product (CIPP) approach and outcome evaluation. The population of this study was all students in the provinces of Riau and Yogyakarta. The research sample is of the students taken randomly from 108 schools that run CFSP. Data analysis used content validity, construct analysis, construct reliability, and descriptive statistics to evaluate the current CFSP. The content validity result shows that only 50 can be used of 56 of the developed items. The construct validity analysis result shows that all indicators obtained from theoretical exploration are valid and reliable. The model fit test shows that the instruments and data obtained from the respondents fit statistically. The results of the evaluation analysis show that the CFSP has been running well, but three indicators are still at a poor level and need to be improved so that the CFSP can run optimally. Indicators needing improvement are the completeness of documents and indicators of student participation, parental participation, community institutions, and the business world. This instrument became the new product to evaluate completely CFSP program because this instrument evaluates not only the process or implementation program but also every process until the program's outcome. Recommendations that need to be considered by stakeholders are to improve CFSP performance so that CFSP can maximally develop student character.
