Abstract

Teaching physics by utilizing technology becomes a necessity for high school physics teachers to master. DIGICOM is an innovation in teaching physics that utilizes multi-technology. Interface-connected camera technology can help explain microscopic phenomena observed through a microscope. A total of 19 physics teachers in Batang Regency, Central Java received training on DIGICOM-based science learning. From the preliminary data it is known that almost all teachers have never carried out learning using multi-technology and only 50% of teachers or schools have digital microscopes and digital cameras in their schools. But after getting DIGICOM training in physics learning, teachers already have sufficient knowledge and they have the confidence to be able to implement the results of this training in learning physics in their classrooms.

Abstract

Making organic fertilizer based on cow dung as an environmentally friendly alternative for modern agriculture. The organic fertilizer produced not only functions to increase fertility land, but also helps manage waste and protect the environment. Making process Fertilizer involves several important stages, such as preventing ingredients, mixing, controlling humidity, aeration and cooling. Studies conducted show that organic fertilizers The resulting product contains good nutrients, provides physical, chemical and chemical improvements biology in soil. This product supports sustainable agricultural practices as well as produce healthier food.

Abstract

Abstract — This experimental study evaluates the use of blotong as a substitute material in the manufacture of paving blocks without using gravel. This study prepared 6 samples, with 2 samples tested for compressive strength at 21 days and the other 4 samples tested for compressive strength at 28 days. The results of this study indicate an increase in the compressive strength of the paving blocks as the age of the test specimens increases, from 50–60 kN at 21 days to 45.89–147.86 kN at 28 days. In this study, one of the samples had the lowest compressive strength, namely sample 6 with 45.89 kN. Sample 6 was tested at 28 days, but still showed the worst compressive strength, which could be attributed to the consistency of the mixture, the consistency of compaction, or the material. All test specimens in this study failed to achieve the standards of SNI 03-0691-1996 for Class D paving blocks, as the water absorption and compressive strength values of the test specimens did not meet the minimum values specified in SNI 03-0691-1996.  Keywords: blotong, paving block, compressive strength, water absorption, SNI- 03-0691-1996.
