E-learning is learning process through electronic media, especially internet. E-learning enables learners to learn or possess science no matter when and where. The goal of this study was to develop Moodle in problem-based learning in order to improve learnersÃ¢â¬â¢ critical thinking skills. . The study was a research and development (R&D) study conducted in four stages, i.e. preliminary study, developing design, testing Moodle as media for problem-based learning, and result dissemination. Subjects of this study were students of physic education program of Faculty of Mathematics and Science Education of IKIP Mataram who enrolled in Wave course. Data on critical thinking skills is collected through tests, where tests have been validated by experts. The results of the study indicate an increase in students' critical thinking skills. Moreover, students gave positive response towards the use of Moodle developed as media in problem-based learning.

This study discusses the use of pumice as an aggregate material to reduce sand in making light brick. The purpose of this study was to, 1) find out the compressive strength of the brick by using a mixture of pumice stone, 2) knowing the exact number of comparisons between sand, cement and pumice to produce a lightweight brick. The research stage was carried out through several stages, namely: 1) Preparation of materials, 2) Making of brick making, on sample A1 (pumice stone 0.50 cm in diameter) with composition (20% SM + 50% PS + 30% BA), A2 (20% SM + 40% PS + 40% BA), A3 (20% SM + 30% PS + 50% BA) while in samples B1, B2, B3 (pumice stone 0.25 cm in diameter) and C1, C2, C3 (rock smoothed float) equal to sample A1, A2, A3. 3) Light brick drying process is carried out for 22 days, 4) density test and compressive strength, 5) data analysis. A lightweight brick made of cubes with a side length of 9 cm (volume 729 cm3). The results showed that the density of the samples A1, A2, A3 in the composition as above were: 1.87 kg / m3, 1.48 kg / m3, 1.73 kg / m3. While the density of samples B1, B2, B3 and C1, C2, C3 as above composition are: 1.43 kg / m3, 1.64 kg / m3, 1.69 kg / m3 and 1.92 kg / m3, 1, 69 kg / m3, 1.57 kg / m3. The best density in sample B1 with a composition of 20% SM + 50% PS + 30% BA = 1.43 kg / m3. The compressive strength values in a row, such as the composition above, are: sample A = 4.66 MPa, 3.97 MPa, 8.29 MPa. Samples B = 5.12 MPa, 6.73 MPa, 6.48 MPa. Samples C = 8.1 MPa, 4.77 MPa, 6.65 MPa. The best compressive strength value on A3 sample with a composition of 20% SM + 30% PS + 50% BA = 8.29 MPa. This study proves that pumice can be used in the manufacture of lightweight concrete blocks that have low density values and high compressive strength.
