Abstract

A pandemic situation such as Covid-19 which is still ongoing has given significant impacts to various sectors such as education, economy, tourism, and social which is in turn impacting the community at a national scale. On the other hand, the pandemic situation has also brought a positive impact on companies engaged in finance that utilizes information technology, namely digital wallets, a company that runs a market place in the digital world. In an effort to anticipate a dynamic market place, the company needs to predict the movement of transactions from time to time by building a model and performain the simulation to such model. Based on this problem, this paper presents simulations on the prediction models based on methods namely, naïve, Single Moving Average (SMA), Exponential Moving Average (EMA), combined SMA-naive methods, combined EMA-naive methods, as well as did the comparison of the best performance of every model by using Mean Absolute Percentage Error (MAPE) measurement. From the results of comparison, it is concluded that exponential moving average method delivers the best performance as prediction tool with MAPE of 23,4%.

Abstract

Teachers' ability in pedagogical competence must be improved. Teachers must always innovate in designing the learning process where learning is the main activity in the education process. Teachers are still found to use learning that is focused not on students. A big challenge for educators, especially elementary school teachers, is to be able to provide interesting and easily understood material for students. Through these challenges, every educator is required to be more creative in delivering material and attracting the attention of students. Observing the conditions that occur at SDN Tlogowaru 1, this activity aims to provide Digital Learning Transformation Training to Improve Teachers' Pedagogical Skills at SDN Tlogowaru 01 Malang. The training participants were 22 teachers with the Participatory Action Research (PAR) Method. The results of Community Service (PPM) activities increased teachers' knowledge and skills in creating interactive teaching materials through flipbook and scratch applications. Teachers are expected to be able to implement them into their learning in their respective classes. PPM participants gave a positive response of satisfaction of 16.36% Strongly agree, 82.73% Agree

Abstract

Hasil observasi terhadap mahasiswa dan dosen yang menunjukkan bahwa kegiatan selama pembelajaran matematika berfokus dengan penyediaan formula praktis dan procedural cenderung menghambat pengembangan kemampuan untuk berpikir kritis mahasiswa. Salah satu kompetensi esensial untuk menilai pendapat, menganalisis informasi, dan membuat keputusan secara rasional adalah kemampuan berfikir kritis. Oleh sebab itu, kemampuan ini diperlukan untuk memahami konsep matematis tingkat tinggi, khususnya menuntut kemampuan analisis seperti persamaan differensial. Kondisi tersebut menunjukkan perlunya model pembelajaran yang dapat mendorong peningkatan kemampuan berpikir kritis matematis yang salah satunya model pembelajaran RCODE. Penelitian ini bertujuan untuk mengetahui besarnya peningkatan kemampuan berpikir kritis matematis mahasiswa melalui penerapan pembelajaran RCODE pada mahasiswa DIII Teknik Elektronika. Jenis penelitian yang dilakukan merupakan penelitian kuantitatif dengan subjek 21 mahasiswa kelas IB semester genap tahun akademik 2024/2025 dengan pokok bahasan persamaan differensial orde dua. Pengumpulan data dilakukan melalui pemberian soal kemampuan berpikir kritis matematis, angket respon, serta wawancara untuk memperkuat temuan kuantitatif. Analisis data menggunakan SPSS dengan pengujian normal, homogen, proporsi, dan pengukuran N-gain. Temuan penelitian menyimpulkan bahwa ketercapaian mahasiswa terhadap Kriteria Ketuntasan Minimal (KKM 67) terpenuhi baik secara individu maupun klasikal dengan persentase ketuntasan sebesar 75%. Peningkatan Kemampuan Berpikir Kritis Matematis (KBKM) mahasiswa setelah penerapan pembelajaran RCODE diperoleh nilai N-gain sebesar 0,47 yang termasuk dalam kategori peningkatan cukup. Rata-rata KBKM mahasiswa mencapai 8,19 pada skala 0–10. Secara lebih rinci, aspek pemahaman terhadap masalah memperoleh skor rata-rata 8,55; aspek perencanaan atau permodelan dalam penyelesaian sebesar 8,26; aspek pelaksanaan dalam penyelesaian dan proses perhitungan sebesar 7,92; dan aspek pengambilan kesimpulan sebesar 8,03. Temuan menunjukkan pembelajaran RCODE mampu memberikan dampak positif terhadap peningkatan KBKM khususnya dalam membantu mereka memahami konsep, menganalisis strategi, mengevaluasi solusi penyelesaian masalah.The results of observations of students and lecturers indicate that mathematics learning activities that focus on the provision of practical formulas and procedural approaches typically impede the growth of students' critical thinking abilities. One of the key skills for information analysis, argument evaluation, and logical decision making is critical thinking. Consequently, it is essential for comprehending more complex mathematical ideas, particularly those that require strong analytical abilities, such as differential equations. These conditions indicate the need for a learning model that can encourage the enhancement of students’ critical thinking abilities, one of which is the RCODE teaching model. The purpose of this study is to ascertain how much RCODE learning of growth students' mathematical critical thinking abilities for Diploma III (DIII) Electronic Engineering students. The research employed a quantitative approach with 21 students of class IB in the even semester of the 2024/2025 academic year as the subjects, focusing on the topic of second-order differential equations. Data were collected through tests of mathematical critical thinking skills, response questionnaires, and interviews to strengthen the quantitative findings. Data analysis was conducted using SPSS, including tests of normality, homogeneity, proportion, and N-gain measurement. The results of the study indicate that students successfully met the Minimum Mastery Criteria (KKM = 67), both individually and collectively, achieving a classical mastery level of 75%. The enhancement of students’ Mathematical Critical Thinking Skills (MCTS) following the implementation of the RCODE learning approach produced an N-gain score of 0.47, which is categorized as a moderate level of improvement. The overall average MCTS score was 8.19 on a 0–10 scale. In more detail, the average score for the problem comprehension aspect was 8.55; for planning or solution modeling, 8.26; for execution and calculation, 7.92; and for drawing conclusions, 8.03. These results suggest that the RCODE learning approach has a positive effect on improving students’ mathematical critical thinking skills, particularly in enhancing their ability to understand concepts, analyze strategies, and evaluate problem-solving outcomes.

Abstract

Penggunaan panel surya secara statis tidak mampu mengikuti pergerakan matahari sehingga menurunkan efisiensi serapan energi sepanjang hari. Untuk mengatasi hal ini, pada penelitian ini dikembangkan sistem solar tracker satu sumbu berbasis logika fuzzy yang mampu mengatur arah panel secara otomatis mengikuti arah datangnya cahaya matahari. Sistem terdiri dari dua sensor DFRobot_B_LUX_V30B yang membaca intensitas cahaya kiri dan kanan, dikendalikan oleh mikrokontroler ESP32 Devkit V1, dan mengatur arah aktuator linear melalui driver IBT-2 menggunakan 16 rule fuzzy. Hasil pengujian menunjukkan bahwa sistem dapat mendeteksi perubahan intensitas cahaya secara responsif, dan menggerakkan panel secara otomatis sesuai arah matahari. Berdasarkan pengujian di lapangan dengan beban, daya rata-rata dari panel dengan sistem solar tracker mencapai 56.06W, sedangkan pada sistem statis hanya mencapai 39.45W, Ini menunjukan bahwa sistem solar tracker berbasis logika fuzzy mampu meningkatkan efisiensi pengisian baterai panel surya sebesar 44% dibandingkan dengan sistem panel surya statis.
