Abstract

The provision of clean water in Indonesia is a people's right guaranteed by the state, especially to meet the minimum daily basic needs for a healthy, clean and adequate quantity, maintained quality and affordable. The availability of fresh water as a source of clean water illustrates the potential for water availability and sustainability. The limited amount of fresh water is a challenge to meet community needs in the form of transportation facilities, toilets for local communities and aquaculture. This condition is also affected by climate change, especially for Indonesia which is in the tropics. The water parameters of the Batang Tapakis River illustrate that the quality of river water is influenced by the people around the river and seawater has entered the river. Community empowerment in providing access to drinking water through community-based activities is a strategic step to overcome the scarcity of fresh water. Participation of the community, government and various related parties can provide reinforcement and commitment so as to achieve the availability of water sources with an insight into sustainable development

Abstract

Most students need help understanding physics material, especially Newton's laws. This is due to the thought that physics material is complex and requires memorizing formulas. This study aims to make it easier for students to understand physics material through Scientific-Based Textbooks. The research method uses research and development, which is used to create teaching material products and test product effectiveness. This study uses four stages: defining, designing, developing, and disseminating. The results showed that the teaching materials made in the form of textbooks were valid according to the results of the validation instruments that the validator had validated. The validator instruments include the eligibility of textbooks in the form of material, presentation systematics, language, contextual aspects, accessibility, navigation, communication, display quality, and the overall function of the media. The results of the percentage of validators related to the language feasibility of the Physics Textbook show the average rate by the two validators, namely 88.3% and 85%. The resulting percentage is feasible because the validity coefficient is > 85%. These results indicate that the Scientific Based Physics Textbook can be used after revision

Abstract

The purpose of this research is to test the validity and feasibility of physics textbooks that have been developed based on Problem Based Learning (PBL) on Newton's gravitational force material. This research uses development research methods. The validation sheet is used as a research instrument. The validation sheet was validated by two experts and declared valid according to predetermined criteria. Textbook validation data was collected from two experts, one textbook media expert and one physics material expert. There are two aspect criteria that are tested for validity, the form of dialogical and interactive presentation of language and the contextual nature of textbooks. The purpose of this research approach is to describe the effectiveness, validity and feasibility of using physics textbooks. The research results obtained are the percentage of aspects of dialogic and interactive language validation as well as aspects of contextual nature that have been tested by material experts obtained an average percentage of 87.5%, which means that the physics textbooks that have been developed are included in the feasible criteria. The results of the research tested by media experts on aspects of dialogic and interactive language as well as on aspects of contextual nature both obtained an average percentage of 100%. This means that a physics textbook based on Problem Based Learning (PBL) on Newton's gravitational force is very feasible to be tested based on validity testing by one material expert and one media expert.

Abstract

A tensimeter is an instrument works with concept of physics used to measure blood pressure. The measured blood pressure is the relative pressure between the pressure inside the blood vessels compared to the pressure of the atmosphere. Blood pressure measurements using a digital tensimeter are much more acurate than measurements using a aneroid tensimeter. Measurements with an aneroid sphygmomanometer at a hospital in the city of Mataram showed a measurement error up to 20 mmHg compared to a digital sphygmomanometer. Source of error consist of two main factors ie. Instrument error and human error. From this research it was found that measurements using a digital sphygmo-manometer are more accurate, so the use of this type of sphygmomanometer is highly recommended for clinical measurements in hospitals and health hospitals.

Abstract

The learning process is still teacher-centered, resulting in students being less active during learning. This research aims to increase the influence of the Problem-Based Learning model on students' critical thinking abilities in mechanical wave material. This quasi-experimental research uses a non-equivalent control group design. The research population included all students in class XI MIPA at one of the State High Schools in East Praya. Sampling used a purposive sampling technique so that 2 groups were obtained, namely 30 experimental class students and 30 control class students. The experimental class was given treatment in the form of using the Problem-Based Learning model, while the control class used the conventional model. Students' critical thinking abilities are obtained from the description questions they work on. Data from the pretest results of experimental class students obtained an average score of 25 and control class students obtained an average score of 23. The posttest scores showed that the critical thinking abilities of experimental class students were in the good category with an average score of 78.6 and the students in the control class were in the good category with an average score of 74.3. The research hypothesis was tested using the polled variance t-test at a significance level of 5%. Data analysis shows that the tcount value, namely 3.384, is greater than ttable, namely 2.002, which means that H0 is rejected and Ha is accepted, so it can be concluded that there is an influence of the Problem-Based Learning model on students' critical thinking abilities in mechanical wave material.
