Learning programming for the first time is very difficult to many students. This difficulty negatively influences the students’ interest in learning programming thus poses a challenge to the lecturers to maintain students’ active involvement in learning. Students find it difficult to grasp the abstract concept of memory location, thus affects their understanding in writing programs. A memory location simulation program (MeLSim) is proposed to assist students with a realistic and visual experience of the abstract memory location concept. The objectives of this research are to develop a memory location simulation program and to determine students' understanding of the memory location concept after using the simulation. The students were given a pre-test and then required to use MeLSim for two weeks. They were then given a post-test. It was found that, there is significant difference on median total scores before and after using MeLSim. From the results, it can be concluded that students’ using MeLSim improved their test scores. This research provides evidence that visualization can assist students in achieving better understanding of the lessons taught which in turn positively influence their test results.

Background. Hypnotherapy is a hypnotic application in curing psychological disorders and relieving physical disorders. The mechanism of action of hypnosis is based on the subconscious. Some scientists speculate that hypnosis stimulates the brain to release neurotransmitters (chemicals in the brain), encephalin, and endorphins and suppress the hypothalamus, which functions to improve mood so that it can change the individual's acceptance of nausea.   Purpose. This research aims to determine the effect of hypnotherapy techniques on the characteristics of nausea in patients who underwent chemotherapy in hospitals Mitra Plumbon Cirebon.   Method. This study used pre experimental methods with non-randomized one group pre test and post test design performed on patients chemotherapy who experienced nausea. The sample in this study is the entire population of patients who have undergone chemotherapy and experienced nausea in the hospital Mitra Plumbon the total samples are 54 respondent data  analysis used Wilcoxon Test.   Result. The result of the research on 54 subjects in hypnotherapy showed the nausea characteristics of chemotherapy patients before and after hypnotherapy was 51 people with decreased nausea, 3 people with the result remained nauseous and nobody experienced increased nausea. Wilxocon Signed Ranks Test Test results obtained significancy value 0.000 (p, 0.05), thus there is a significant difference of nausea characteristics before after hypnotherapy. Conclusions. This suggests that hypnotherapy is effective and effective against the reduction of nausea characteristics in chemotherapy patients. It is hoped that the action of hypnotherapy can be made as an intervention in dealing with nausea.

Smoking in adolescence is increasing. Prevention of smoking behavior in adolescents is needed, one of which is to predict behavior according to the Theory of Planned Behavior (TPB). In this TPB, it is explained that individual attitudes are predictors that can influence an individual's decision to perform a behavior. Therefore, it is necessary to have an intervention that can be used to influence individual attitudes about smoking behavior in order to reduce smoking behavior, especially in adolescents. The design of this research is one group pre test-post test. Univariable analysis was used to calculate the frequency to determine the characteristics of the respondents which included gender, age, class, smoking status and age for the first time trying smoking. Bivariable analysis was used to determine differences in attitudes, before and after being given counseling using the Wilcoxon test. The results showed that the majority of respondents in this study were women (53.48%), the majority had an age of 17 years, which was 62.79%. The majority consisted of teenagers in class XI, which was 65.12%. In the smoking status of adolescents, it is known that the majority of adolescents do not smoke, which is 67.4%. In adolescents, it was also known that they had tried smoking for the first time, namely at the age of 13 years. In the bivariable test, there was a significant difference in adolescent attitudes towards smoking behavior between before and after counseling with a p value of 0.001 (p <0.05). The conclusion of this study is that there is an effect of education with booklets on adolescent attitudes towards smoking behavior.Keywords: booklet;education;adolescent;attitude,smoking AbstrakMerokok pada usia remaja semakin meningkat.

One of the topics students have understanding difficulties in science is pressure. The study investigates the effectiveness of an active-learning environment on the students' understanding of the concept of pressure. The sample consisted of 30 students from a public secondary school in Turkey. This study used a pre-test, post-test, quasi-experimental research design with a control group. Ten lessons were conducted with both groups. The control group was taught using the coursebook's two activities, while the experimental group was taught using additional activities and models. After the treatment, a post-test was given to both groups to determine the active-learning environment's effectiveness on the students' understanding of the concept of pressure. Interviews were also conducted with the experimental group. The post-test results showed a significant difference in favor of the experimental group. It was determined that students in both groups had misunderstandings of the topic before and after instruction. The interviews showed that the experimental group students perceive that the active learning environment facilitated better and easier learning. The conclusion that can be drawn is that the active learning environment was more effective for the students in the experimental group to learn about the concept of pressure.
