Organic Waste Crushing Machine Automation in Eco Enzyme Production
No full textIn 2025, Indonesia has launched a zero-waste program. Towards a zero-waste program, of course, the community is given awareness in sorting and processing waste. Waste management is a common problem in urban or rural areas, along with the increase in population and people\u27s lifestyles. Waste problems that are not handled properly can cause environmental problems (pollution of air, soil, and water) and public health. Based on the origin, waste is divided into organic and inorganic waste; organic waste is produced from biological materials that can be degraded by microbes or are biodegradable, or waste from fruit, vegetable, and leaf residues. This organic waste is the majority of the waste generated from households, so it is necessary to think about how to process it that is beneficial and efficient. One of these organic waste processing is processed into Eco enzymes, namely processing organic waste with molasses and water in a ratio of !:3:10. The organic waste processing process is first chopped to become a small part to facilitate the fermentation process. The automation of this chopping machine uses Arduino as a microcontroller, a load cell as a measure of the weight of organic waste, an electric motor as a driving force, a solenoid door lock as a lock for the organic waste load before grinding, and a knife as an organic waste count. The purpose of making this tool is to help chop organic waste in the process of processing eco enzymes. The research results on the automation of this organic waste chopper machine loadcell with a load of 1 Kg runs well; the solenoid door lock can hold organic waste to work well. The research results on the motor for upper milling are given a large torque equipped with a downward knife position and a pillow block so that the motor does not shake

Comparison of Web 2.0 Use on State University Websites in Indonesia and Top World Universities Related to Webometric Ranking
No full textThe present work determines the presence in the web 2.0 that twenty universities had through their educational portals. The universities are selected according to the Webometrics ranking (the ten best located in Indonesia and the best located worldwide) to identify what Web 2.0 tools they use. This study explores the educational portals of the twenty selected universities to determine which Web 2.0 tools they use and variables of the tools found will be assessed. The study only considers those Web 2.0 tools which are linked to the websites of universities. Of the two most used tools, the relevant indicators are quantified from Youtube Subscribers and Views and Twitter tweets following , and followers . Afterward, the results are shown and analyzed to establish possible relationships between the indicators of each tool. The results reflect the heterogeneous and, in many cases, polarized presence that universities had on web 2.0 through their educational portals. We hope that the work will help universities have a verifiable reference instrument to develop their academic communication strategies through these tools on the way to a 2.0 university model
Manga versus webtoon: Alternative science learning module based on Dr Stone
No full textReading activities for junior high school students in Indonesia are carried out at school when the instructor requests that they study the learning topic being taught. Therefore, learners may become bored due to the thickness of the available books. Indonesian students are more likely to read when they encounter visualizations in images, and a small amount of text, commonly referred to as comics. Students like reading numerous popular comics, such as manga and webtoons, but it is exceptionally uncommon to discover a popular comic that teaches the subject of a specific discipline, particularly natural sciences, which has a challenging scientific picture. This study aims to examine the many forms of manga comics and webtoons that may be utilized as alternative student learning modules when students study from home without regard for space or time constraints during the covid-19 epidemic. The descriptive qualitative research approach was applied. Manga comics, particularly Dr Stone\u27s manga, were more acceptable for use as alternative scientific learning modules in junior high schools in terms of completeness of module parts and learning contexts. Comic Dr Stone can boost learners\u27 cognitive and psychomotor skills by vividly seeing daily situations. This research is intended to be expanded by further researchers to give more alternative module alternatives for students and aid teachers in educating Indonesian learners
