Kejadian dismenorea primer di Indonesia sekitar 54,89%, sisanya 45,11% dismenorea sekunder. Dismenorea primer  pada siswi SMP X dari 35 siswi 25 siswi mengalami disminor bila haid. Salah satu pengobatan dismenorea secara non-farmakologis yaitu hipnoterapi. Hipnoterapi merupakan salah satu cara yang mudah, cepat, efektif, dan efisien dalam menjangkau pikiran bawah sadar. Penelitian ini bertujuan untuk mengetahui pengaruh hipnoterapi terhadap dismenorea pada siswi SMP. Metode penelitian yang digunakan adalah Pre Eksperimental dengan rancangan penelitian one group pre-test-post-test. Jumlah populasi yang didapat 117 orang dan jumlah sampel yang diambil 20 orang, dengan teknik purposive sampling. Pengumpulan data diperoleh secara langsung dari responden dengan menggunakan alat ukur Verbal Descriptor Scale (VDS). Analisis data melalui dua tahapan, yaitu univariat dan bivariat dengan menggunakan uji t-dependen. Hasil penelitian didapatkan nilai rata-rata skala dismenorea sebelum diberikan intervensi adalah 6,50 dan nilai rata-rata sesudah diberikan intervensi adalah 1,35, terdapat pengaruh hipnoterapi terhadap dismenorea (t=17,596, p-value= 0,001). Hipnoterapi dapat disarankan untuk diterapkan sebagai tindakan nonfarmakologis untuk mengatasi dismenorea.Kata kunci: Dismenorea primer, hipnoterapi, SMP.Effect of Hypnotherapy on Alleviating Primary Dysmenorrhea in Junior High School StudentsAbstractThe incidence of primary dysmenorrhea in Indonesia amounts to approximately 54.89%, while another 45.11% is secondary dysmenorrhea. 25 out of 35 female students at SMP Patriot Bangsa (Patriot Bangsa Junior High School) experience primary dysmenorrhea when menstruating. One of nonpharmacological treatments for dysmenorrhea is hypnotherapy. Hypnotherapy is an easy, fast, effective, and efficient way to treat dysmenorrhea by reaching the subconcious. This research aimed to identify the effect of hypnotherapy on dysmenorrhea in junior high school students. This research used a pre-experimental method with one group pretest- posttest design. The population of this research was 117 students and 20 students were chosen as sample with purposive sampling technique. Data were collected from respondents using Verbal Descriptor Scale (VDS) instrument. Data were analyzed in two steps, univariate and bivariate with t-dependent test. The results showed that the average value of dysmenorrhea before intervention is 6.5 and after intervention is 1.35. Hypnotherapy was found to have an effect on dysmenorrhea (t=17,596, p-value 0,001). It was suggested to the school that they should conduct nonpharmacological interventions such as hypnotherapy as treatment of dysmennorhea.Key words: Dysmenorrhea primer, hypnotherapy, SMP.

This study aim to determine the effect of Problem Based Learning (PBL) models in mind map integration to creativity of problem solving in the environmental pollution concept of graders X. The method used is a Quasi-experimental design form Nonequivalent Control Group Design (pretest- posttest). The study population is all the students of graders X academic year 2017/2018 as many as 9 classes with the number of 360 students. The sample used was 80 students from two classes as an experimental class and a control class. Sampling was done by Cluster Random Sampling technique. Instruments used include test descriptions, questionnaires and teacher observation sheets. The results of the analysis of the test descriptions creativity in problem solving obtained results of hypothesis testing (t test) i.e. 20.5 t count > t table of 2.66 means that Ho refused and Hi accepted, it means PBL learning models in Mind Map integration effect on creativity in problems solving. This is indicated by an increase in the average score on each indicator of creativity in problem solving in which students are able to grow various ideas, enrich ideas, add or detail the details of an idea and determine the truth to solve the problems. From the analysis of questionnaire data showed an interest in learning to use the PBL modela in Mind map integration, students agreed that if the model of PBL in Mind map integration may be easier to learn about the concept of Environmental Pollution. In addition, students also agreed that if the PBL models in Mind map integration effect on creativity in problems solving. The results showed that there was a significant influence between learning using PBL models in Mind map integration those not using the learning models to creativity in problems solving in the concept of environmental pollution of graders X.

Burhān al-Dīn al-Zarnūjī in his treatise Ta'līm al-Muta'allim Ṭorīq al-Ta'allum proposed that the academic achievement has six things dependency: ingenious acumen, fervent desire, patience, sufficent sustenance, guidance of a teacher, and length of time. In other side, Paul Stoltz in his book Adversity Quotient: Turning Obstacles Into Opportunities coined adversity quotient term as a score that measures the ability of a person to deal with adversities in his or her life. Hence, adversity quotient is commonly known as the science of patience. Based on this perspective, we was empirically tested students scientific literacy through correlational research. In particular, first adversity quotient was measured with Adversity Response Profile (ARP) includes four dimensions that are characterized as control, ownership, reach, and endurance. Second, scientific literacy was tested with Scientific Literacy Test (SLT) that focused on three competencies. Third, we used Pearson r to elaborate correlation of scientific literacy with adversity quotient. The participants of the study were 50 students in Kabupaten Kudus choosen by purposive sampling technique. The findings suggest that it is important to facilitate students’ adversity quotient to guide them on achieving scientific literacy.
