This research was carried out with the aim of finding out the effect of the jurisprudential inquiry learning model on the ability to write editorial texts. The population of this study was all class XII of SMA Negeri 2 Tanjung Morawa, totaling 7 classes. The sample was taken with no more than 40 students per class, so class XII Science 2 had 35 students as the experimental class and class XII Science had 34 students as the control class. The instrument used is a test of the ability to write editorial texts. Data measurements were carried out twice, namely measurements in the experimental class and the control class. From the data processing, it shows that the ability to write editorial texts in class .05, standard deviation 13.15. This can be seen in the normality test, the jurisprudential inquiry learning model is Lcount < Ltable namely 0.205 < 0.337. Then in the conventional learning model Lcount < Ltable, namely 0.192 < 0.319. Because Lcount is smaller than Ltable, the two data above are said to be normally distributed. Likewise, the results of the data homogeneity test are Fcount < Ftable , namely 0.54 < 0.56, so the data comes from a homogeneous population. After testing normality and homogeneity, hypothesis testing was carried out, obtained tcount > ttable  with hypothesis test results of 6.35 and significance a = 0.05 and df = 35+34-2 = 67, so at the 5% level we obtained ttable = 1.99601. Thus it can be concluded that tcount > ttable , namely 6.35 > 1.99601, so the null hypothesis (H0) is rejected and the alternative hypothesis (Ha) is accepted. This proves that the jurisprudential inquiry learning model is more influential in improving the editorial text writing skills of class XII students at SMA Negeri 2 Tanjung Morawa.

Integrative learning is a study that contains more than one subject into a particular learning theme, so that it can provide students with experience in the learning process by using a field of study approach. The integrative learning process can be seen in aspects such as the time aspect and learning process, curriculum aspects and teaching aspects. Based on the results of observations that have been made, students' motivation and interest in learning is low. This is shown by students' lack of enthusiasm in participating in learning due to monotonous learning, teachers still using a dictation system and the provision of learning tools being inadequate so that the learning process feels saturated and boring. Therefore, the activity of implementing this integrative learning model requires students to be more active than the teacher who is the guide in the learning process. As for the steps that must be taken in this learning activity, students must interact with the learning material and must interact with learning resources so that they can easily master the concepts and indices in the integrative learning process.
