This study aims to find out wheter there is an influence of the Hot Potatoes multimedia application in evaluating junior high school students' learning outcomes in Indonesian language learning. The study design uses an evaluation model with the multimedia application Hot Potatoes. The method used is quantitative description and qualitative description, which is to show the effect of evaluating student learning outcomes and student and teacher responses to the effectiveness of the use of multimedia Hot Potatoes. The data source of this research is the IX grade junior high school students in Buru Regency. Data collection techniques used in this study are test techniques using the multimedia application Hot Potatoes in the form of a Multiple-Choice Test (multiple-choice). The results showed that the application of the Hot Potatoes multimedia application in evaluating the learning outcomes of junior high school students in Indonesian language learning had a major influence on quality learning. This can be seen from the results of the evaluation of 50 middle school students from cycle I, cycle II, and cycle III. The percentage of students completeness in cycle I was 60%, cycle II was 86%, and cycle III was 94%. Meanwhile, the percentage of students completeness in the first cycle was 40%, second cycle was 14%, and third cycle was 6%.

In developing the character of environmental awareness and disaster response, the School of Care Partners (CPS) was launched which targeted teachers and students as partners. This is an effort to internalize the character of environmental care and disaster response to students and find out the teacher response from CPS and also helps CPS follow-up plans as commitments with students. This type of research is qualitative descriptive research. Data collection is done by Focus Group Discussion, questionnaires, and documentation. The sampling technique used was a sample and a population of 16 teachers at Baubau High School 2. Data analysis using qualitative analysis. From the results of data analysis, conclusions are obtained the efforts of teachers and students to internalize the character of environmental care and disaster response to students, namely through school learning activities and the application of daily activities in schools such as environmental cleanliness and disaster anticipation simulations and 100% school teachers respond positively and agree with the CPS program and participate in implementing it. The follow-up plan for the CPS program includes forming a branch coordinator in each target school in Baubau City as a node for the CPS implementing teacher, socialization to each school regarding the CPS program and pioneered the establishment of CPS extracurricular activities in each school as partakers in CPS implementation.

The purpose of this study was to find out (1) The effectiveness of the E-JAS model with the science edutainment approach to improving environmental care behavior (2) Effectiveness of the E-JAS model with the science edutainment approach to increasing responsibility behavior (3) Citizen response to the E-model JAS with a science edutainment approach. The method used in this study is the pre-experimental design method. Sampling in this study using purposive sampling. The results showed that the E-JAS model with a science edutainment approach could improve environmental care behavior by 73% with a high category, can increase responsibility behavior by 65% with the medium category, and citizen responses to the E-JAS model with the science edutainment approach in the category well.

Most surface layers in the Papua and Kalimantan regions are Laterite Land. When dry lateritic soil dries but when containing large amounts of water, laterite soil becomes overtime. Cement production requires a lot of energy so that geopolymer concrete and mortar is a material that has great potential as an alternative to reduce the use of Portland cement because it has mechanical properties that almost resemble Portland cement-based concrete. This study discusses the use of fly ash and alkali activator (NaOH and Na2SiO3) to bind laterite soil by adding quenched lime to reduce the use of ovens to form geopolymer mortar. Comparison of laterite and lime outages is used, namely 95%: 5% and 90%: 10%. Testing of the flow of fresh geopolymer mortar shows that all materials can be bonded well and no segregation occurs. The hardened test material is treated in air-exposed for 3, 7 and 28 days. Testing of compressive strength was analyzed to determine the behavior of geopolymer mortar. The test results showed that there was an increase in compressive strength from the age of 3 to 7 days but decreased at the age of 28 days due to rainy weather, sunlight which resulted in the specimen experiencing flowers (during rain) and shrinkage (during hot weather) so that cracks occurred cracks in specimens, as well as the use of comparison of laterite and lime soils, extinguished 90%: 10% resulting in better compressive strength compared to the use of the ratio of laterite and lime outages of 95%: 5%.
