Abstract: The purpose of this research is to fix process and improve the student’s mathematics learning outcomes in class VII5 SMP Babussalam Pekanbaru by using Problem Based Learning (PBL) model in 2017/2018 academic year at Aljabar form material. This research is a colaborative action class research where the researcher and the teacher of matematics in class VII5 SMP Babussalam Pekanbaru were colaborated in planning, doing action, doing observation, and reflecting. The sample of this research is 16 female students of class VII5 SMP Babussalam Pekanbaru with heterogen intelligent. The instrument of data collection in this research consist of observation sheet and assessment sheet. Data collection techniques in this study consisted of observation techniques and test results of mathematics learning techniques. The analysis technique used is descriptive descriptive data analysis technique and descriptive statistical data analysis. Data obtained from the observation sheet is qualitative data and analyzed by descriptive quantitative analysis technique. Data obtained from the learning result test were analyzed by descriptive statistical analysis technique. The result of data analysis show teacher’s and student’s activity have been done very well in cycle II and weakness/deficiency that happened less from cycle I to cycle II. Implementation of PBL model enables students to observe and understand problems and can collect information related to problems given by teachers. The students 'mathematics learning outcomes also increased in UH I and UH II seen from the achievement of students' knowledge and skills and frequency distribution analysis. The results of this analysis indicate that the application of PBL model can improve the learning process and improve students' mathematics learning outcomes of students of grade VII5 SMP Babussalam Pekanbaru in 2017/2018 academic year at Aljabar form material.Key Words : Problem based learning model, mathematics learning outcomes

Abstract

Corn (Zea mays L.) is one of the important food commodities in Indonesia. The use of corn, especially as an industrial raw material and animal feed, continues to increase. Increasing corn production can be done by utilizing sub-optimal soils, one of which is saline soil. The purpose of this study is to determine the effect of compost fertilizer, arbuscular mycorrhizae and biosaka on the production of corn plants in saline soil. The research consisted of 5 treatments, namely; chemical fertilizers., compost fertilizers., Compost fertilizers and arbuscular Mycorrhiza., Compost and Biosaka., Compost fertilizers, arbuscular mycorrhiza, and Biosaka. The results of the study were that the compost fertilizer treatment gave the best results at the plant height of 162.08 cm, the stem diameter was 18.15 mm, the weight of corn was 130.08 grams, the weight of seeds per cob was 236.33 grams, the weight of the cob was 89.00 grams, the biomass weight was 14.27 grams and the production per hectare was 16.88 tons/ha. Compost fertilizer and arbuscular microza treatment gave the highest number of leaves, which was 10.17 sheets. Compost fertilizer treatment provides better results for plant height, stem diameter, fruit weight, seed weight, cob weight, biomass weight and production per hectare and Combination treatment of compost fertilizer, arbuscular mycorrhizae and biosaka does not provide the best results for the growth and production of corn plants planted on saline soil.
