Students' collaborative thinking skills in the elementary schools still need attention to be improved. Most elementary school students have difficulty in cultivating this skill. Even though, this skill is one of the 21st century skills, namely 4C (creative thinking skill, critical thinking skill, communication skill and collaborative thinking skill). This study aims to improve the students collaboration thinking skills under the implementation of a cooperative learning type, namely a quantum teaching model. This research was conducted by using quasi experiment in the form of non-equivalent (pre-test and post-test) control group design. The sample in this study were students of the Integrated Islamic Elementary School, Al-Musabbihin, Medan City, totaling 55 students. To test the difference of the students' collaborative thinking skills in the control class and experiment class under the implementation of quantum teaching model, we used statistics analysis tools, namely homogeneity test and independent sample t-test. The results of Levene Statistic for homogeneity test showed a significance value of 0.762 > 0.05, which means the two classes are homogeneous. The independent sample t-test showed that the score is 0.007 < 0.05, which implies the difference between the two classes is significant. It concludes that the implementation of quantum teaching model can improve the students' collaboration thinking skills in Islamic Religious Education Learning. Therefore, increasing the teachers skills in developing quantum teaching learning materials needs to be improved simultaneously through government policy programs or independently through deliberation activities for teachers of Islamic religious education subjects.

Pengembangan karakter anak usia dini harus menjadi prioritas. Karena saat ini, karakter bangsa kita sudah mengalami reduksi di seluruh lini kehidupan. Apalagi metode bercerita  yang digunakan dalam mengembangkan karakter anak kurang maksimal. Hasil observasi, guru di TK ABA Aisyiyah se Kota Medan juga belum maksimal menggunakan metode bercerita tersebut untuk mengembangkan karakter anak. Tujuan penelitian ini adalah menghasilkan prototype model pengembangan bercerita dengan teknik Chain Story. Subjek penelitiannya adalah para guru TK ABA di Kota Medan. Metode penelitiannya menggunakan analisis dokumen, observasi, wawancara, dan FGD. Teknik Chain Story dilakukan berpusat pada anak, guru sebagai pemantik cerita berdurasi singkat. Anak bebas bercerita dengan kata-kata, cara, dan gayanya sendiri. Namun, kontennya  tetap sesuai dengan tema dan tujuan pembelajaran yang telah ditetapkan. Guru mengawasi jalannya pembelajaran, menilai kemampuan dan karakter saat anak sedang bercerita. Penelitian ini berimplikasi pada penerapan metode bercerita yang tidak lagi berpusat pada guru, tetapi menjadi berpusat pada anak (Child Centered-Learning)

The problem of garbage is a classic problem that repeatedly faced by the surrounding residents, especially in the Village of Peace. Because of the amount and level of danger, waste, especially plastic waste composed of chemicals, is difficult to decompose so that it is dangerous for the environment, so it is necessary to process waste to turn plastic waste into something useful. Based on surveys in the peaceful village area, North Binjai people still mostly do not have a fixed income. The implementation of the results of plastic bottle waste treatment into liquid hand soap packaging products in Damai Village was carried out to raise awareness of residents and provide ideas on how to increase their income. In addition, it can minimize pollution, so that the residents of The Peace Village can be more concerned about environmental cleanliness. The methods used in the program of utilizing plastic waste as packaging products are divided into two, namely the stage of exposure or explanation and the stage of practice to the community. Through training and mentoring the manufacture of hand washing soap and the utilization of plastic bottle waste, residents get insight into business opportunities that can be created through these creative ideas, and residents are already able to make liquid hand soap that can be sold. Through the training program on making hand soap in Damai Village, it is hoped that it can be an alternative to the use of plastic bottle waste which can be a product that can help improve the economy of the surrounding community.
