Today's technological developments provide very real changes in human life. There are many tools made to facilitate human work. With advances in science and technology, innovations are developed that are better. Automatic control systems in the field of science and technology lately also growing rapidly. This can be seen from the range of applications ranging from household to sophisticated equipment. Automatic curtains using Arduino-based light sensors are an idea that arose to meet the needs of home automation systems. Automatic curtains work based on the intensity of light that is captured by the light sensor and is real to be processed by Arduino and gives the task of the driving motor to carry out orders to go up or down the curtain according to the light intensity settings that have been set to the system. Simply put, when the light intensity is 271 - 1000 lux then the curtain goes up, then if the light intensity is 1001 lux the curtain will go down, and if the light intensity is 270 lux then the curtain stays down or closed.

Tesso Nilo National Park is one of the protected areas designated as KPA by the Decree of the Minister of Forestry No.225/Menhut-II/2004 dated July 19, 2004 covering an area of ​​38,576 ha, then expanded again through the Decree of the Minister of Forestry No.663/Menhut/2009 dated 19 October 2009 with an area of ​​± 83,068 ha. The Tesso Nilo National Park area is experiencing the dynamics of land cover changes, namely the conversion of forest land which causes the forest area to become increasingly narrow in this area. With the reduction in forest area in this area, it causes a decrease in ecosystem network connectivity due to forest fragmentation that occurs, so that forests are separated and further apart. This study aims to analyze changes in land cover in the Tesso Nilo National Park area to find out information on changes in habitat ecosystems in the last 20 years. the observations were made using satellite images in 1999, 2010 and 2019. so that it can be seen the effect of forest fragmentation on ecosystems in the Tesso Nilo National Park area. From the results of the analysis, it was found that the area of ​​forest cover in the Tesso Nilo National Park decreased from 1999 to 2019 and caused changes in the connectivity network of forest ecosystems, which was found in the study, the weakest connectivity separated forest fragments as far as 17394.47 meters due to forest cover fragmentation.

This research is based on the problem of modules used by lecturers in Electrical Materials Science courses who are still not able to encourage students to be able to study independently because the modules used have not directed students to be able to find learning concepts and the material in the module does not fully cover every competency. The syllabus is applied based on the curriculum. The material presented by the lecturer in the regulatory system course at the Faculty of Engineering, Padang State University, has not been fully understood by students. This is because the material is not conceptual, and also less interactive so sometimes students feel bored and do not have the motivation to study independently after or before learning. This has an impact on the one-way learning system, where students only expect explanations from the lecturer. This study aims to produce an E-Module for Electrical Materials Science courses that are valid, practical, and effective. This study used development research methods using a 4D model, namely define, design, development, and dissemination. While the subjects in this study were students of Electrical Engineering, Padang State University. The subjects of the research were students of the Faculty of Engineering, Department of Electrical Engineering. The research instrument is a validity questionnaire, a practicality questionnaire, and a test. The results of the study obtained the validity of the E-Module data from material experts and media experts with valid categories. Practical test with the lecturer and student respondents obtained E-Module learning Electrical Materials Science is included in the very practical category. Test the effectiveness of the E-Module in Electrical Materials Science through the results of the post-test. Students obtained that the E-module is in the effective category.

Degenerative diseases are developing today. One of them is gouty arthritis, also known as gout. This disease is very common in society. In Indonesia, the prevalence of gouty arthritis is 34-32 years old. According to a report from the Padang City Health Office in 2018, gouty arthritis was ranked the 4th highest disease in the city of Padang after gastritis. The highest prevalence was in North Padang District with 400 sufferers and Alai Health Center ranked 2nd with 118 cases. Gouty arthritis is characterized by high levels of uric acid in the blood (hyperuricemia). Arthritis is rarely fatal, but can be stressful for patients. The therapy used is anti-inflammatory drugs with many side effects. Turmeric (Curcuma longa) is one of the herbal plants that has the potential to treat rheumatism and gout. Turmeric (Curcuma domestica Val) is an herbal plant with anti-inflammatory properties for gouty arthritis. The large old turmeric rhizome is often used as medicine. Turmeric contains the active ingredient curcumin. It has been extensively studied as an anti-inflammatory drug. This is because curcumin can inhibit the protein Cyclooxygenase-2 (COX-2). COX-2 is an enzyme that mediates inflammation. Therefore, the curcumin in turmeric has a potential anti-inflammatory effect and can be used as the basis for the treatment of artritis gout.
