This phenomenon happened because of some factors. One of them was an unmotivated learning indicated by the laziness to engage the teaching learning process, such as the frequent going in and out of the class, absence, and not doing the task given by the teacher. This research aimed at investigating in what extent the influence of students’ learning motivation towards the learning achievement of the students having under minimum passing grade at the entrepreneurship subject at SMK Muhammadiyah 1 Pekanbaru. The population of this research was 183 students with 65 students as the samples. Probability sampling, simple random sampling, is used as the technique to gain the sample in this research. The data were collected using observation, questionnaire, and documentation. Based on the data analysis, it can be concluded that the significance value in the coefficient table 0.000 is less than critical value 0.1. Thus, it is obtained that 0.000 < 0.1, which means that the students’ learning motivation influences the students’ learning achievement in the entrepreneurship subject at SMK Muhammadiyah 1 Pekanbaru. Viewed from the R square 0.207 shows that the independent variable student learning motivation used in this research is influenced by the dependent variable student learning achievement at the rate of 20.7%. Thus, it can be said that the capability of the independent variable student learning motivation in influencing the dependent variable student learning achievement is high. Based on the calculation of t test, the t table 4,057 > t quantification 1.998 (Ho) is rejected or sig 0.000 < 0.05 (Ha) is accepted. It means that there is an influence of the students’ learning motivation towards the students’ learning achievement. Based on the regression coefficient, if the students’ learning motivation happens to increase at rate of 1%, the students’ learning achievement also will increase at the rate of 0.284 or 28.4%. The positive coefficient shows that there is positive correlation between students’ learning achievement and students’ learning motivation. The more students are motivated, the more students will reach the achievement.Keywords: Students’ Learning Motivation, Students’ Learning Achievement2

Composting process using two activators, namely Effective Microorganism 4 (EM4) and activated sludge. Mature compost meet the requirements of SNI 19-7030-2004. The best results were obtained in variations 5 using EM4 activator with a ratio of sludge: onion skins: fried onion = 8:2:1 with results C-organic 22.44%, 1.50% N-total, P-total 0.52 %, K-total of 1.08% and the ratio of C / N 14.92. In activated sludge activator with a variation of the same C-organic shows the results of 19.64%, 1.29% N-total, P-total of 0.39%, K-total 0.52% and the ratio of C / N 15.27.
