Aplikasi ESP32 Untuk Monitoring dan Perawatan Aquascape

Aquascape adalah seni menyusun tanaman dalam air seperti pasir, batu, ranting dan komponen lainnya dalam suatu aquarium yang terkesan menghasilkan ekosistem buatan mirip dengan aslinya. Faktor penting dalam aquascape adalah kualitas kekeruhan air, proses fotosintesis, pemberian pupuk dan pemberian pakan ikan. Dari faktor diatas menjadi sebuah kesulitan untuk  para penghobi agar dapat menjaga keberlangsungan kehidupan ekosistem, namun karena keterbatasan waktu dan kesibukan, para penghobi menemukan banyak kesulitan. Maka perlu adanya inovasi alat agar perawatan aquascape dapat berjalan secara otomatis, seperti mendeteksi kekeruhan dengan sensor turbidity, proses fotosintesis buatan dengan lampu LED, proses pemberian pupuk dengan minipump dan pakan ikan menggunakan motor DC. Semua alat dirancang menggunakan ESP32 yang dihubungkan dengan telegram sebagai monitoring perawatan. Pada umumnya ramgka awal yang dilakukan mencari studi literatur untuk membuat rancangan sistem dan desain sesuai kebutuhan sebelum dilakukan pengujian dan analisa hasil. Tahap kedua yang dilakukan antara lain pengujian sensor dan pengujian waktu. Tahap yang terakhir yaitu evaluasi analisa pada sistem untuk mengetahui selisih sistem yang diprogram dengan realisasi alat yang diterapkan

Learning Application Derivative Algebraic Functions: Ethnomathematical Studies and Digital Creator Books

Learning mathematics has been meaningful if it is associated with real-life problems. Ethnomathematics is an activity in which mathematical concepts are related to the local "Lontong Sayur" culture that students often encounter in real life. Ethnomathematics needs to be applied to students at the high school level. It aims to make it easier for students to understand mathematical concepts, one of which is ethnomathematics based on Digital Book Creator. This study aims to create a product as a Book Creator based on the application of ethnomathematics in learning. Applications derived from algebra help teachers create conducive conditions for students to learn. The development model used in this research is the Borg and Gall development model in the research and data collection stages. Book Creator is a simple tool for creating exciting books. The validation of materials, learning media, and culture received a score of 3.58 using "good" criteria. Book Creator can be developed to understand documents more in context to understand documents from concrete to abstract and provides several menus, namely: a) Presenting user guides and brief descriptions of Book Creator; b) Business plans and concept maps; c) A summary of the material is presented in stages equipped with sample questions and quizzes containing learning videos, audiovisual sections, and aptitude tests; and d) Summarizing, presenting summary/basic learning materials

ANALISIS KEMAMPUAN BERPIKIR INTUITIF SISWA SMP DALAM PENYELESAIAN MASALAH PADA MATERI SEGI EMPAT

Intuitive thinking is very important to use in solving rectangular area problems. because by thinking intuitively students are able to generate creative inspiration impulsively. The emergence of intuitive thinking in solving rectangular area problems is the solution to getting the right answer. The purpose of this study was to find out students' intuition in solving rectangular area problems. This research is descriptive research with a qualitative approach involving 7 students as potential subjects. Two students become the main subject because the answers meet the indicators of intuitive thinking. procedures in this study: 1) determine the material; 2) make test questions; 3) giving tests to prospective subjects; 4) Analyze the answers of prospective subjects with the indicator rubric; 5) Selected as a subject; 6) Conducting interviews on the subject; 7) Analyze the results of interviews from the subject. Collecting data on students' intuitive thinking in solving rectangular area problems using written test instruments and interview tests. Data analysis in this study consists of three categories of intuitive thinking (Catalic Inference, Power of Synthesis, Common Sense). The results of this study are subjects with catalic inference intuitive thinking categories giving short answers and no logical reasons and subjects with Power of Synthesis intuitive thinking categories giving answers that are less organized while common sense intuitive thinking categories giving thorough answers using complete arguments. The categorization in this study is viewed from indicators of intuitive thinking that have been achieved by students in the process of solving questions and interview tests.

The Role of Teachers and Communication Information Technology (ICT) Media in the Implementation of Mathematics Learning in the Digital Age

The current era of modernization has brought the Indonesian nation forward in the development of science and technology. This is marked by the existence of information and communication that spreads quickly in life, including in the world of education. Along with the development of ICT, one must also be able to adjust, sort, and utilize the development of information and communication so that it can make a positive contribution to students. The purpose of this study was to describe the role of teachers and information communication technology (ICT) media in the implementation of mathematics learning in the Digital Age. This research is a literature study with a descriptive qualitative research type with a literature review that seeks to describe the role of educational innovation in digital technology-based learning. In this study, the authors used various written sources such as articles, journals, and documents that were relevant to the studies in this study. This Literature Study focuses on the role of a teacher in learning mathematics, digital technology in education, and the use of technology in education, as well as digital-based learning media. Learning has an important role in efforts to improve the quality of education, so that learning can bring meaning and benefits to students. The conclusion in this paper is that ICT mastery is an indicator of a teacher's competence. The selection and use of ICT media must be correlated with learning and adapted to the needs of learning activitie

The Effectiveness of Independent Learning on Student Mathematical Learning Outcomes in Online Learning

Learning independence is something that plays a very important role in improving student learning outcomes, so that both educators and other parties must pay attention to the learning independence possessed by students. This study aims to determine the effectiveness of student learning independence on learning outcomes in online learning. The method used in this research is SLR (Systematic Literature Review). In this study identification, assessment, and description of the results of the research will be carried out. In this study the researcher will review and systematically identify articles/journals which at each stage are in accordance with what has been determined.
