PENGEMBANGAN MEDIA PEMBELAJARAN KOTARANG (KOPER TAMBAH KURANG) PADA MATA PELAJARAN MATEMATIKA DI KELAS II SEKOLAH DASAR

Learning takes place at SD Muhammadiyah 4 Batu which uses the Merdeka curriculum in classes I, II, IV and V, while classes III and VI still use curriculum 13. Learning will be effective and enjoyable if accompanied by learning media. . The aim of this research is to develop Kotarang learning media that motivates students to learn. With the development of learning media, it is hoped that students will be able to understand addition and subtraction material in class II elementary school mathematics learning. This study uses the ADDIE development model consisting of 5 stages, namely (1) analyze, (2) design, (3) development, (4) implementation, and (5) evaluation. ). Data collection techniques use observation, interviews and documentation. The data analysis techniques used are qualitative data analysis techniques and quantitative data analysis techniques. Data were taken in class II at Muhammadiyah 4 Batu Elementary School with a total of 25 students and carried out on September 6-7 2023. The results of this study resulted in a product in the form of Kotarang learning media. The research has gone through the stages of validation, namely material validation to get a percentage of 93% and media experts 92%. This study received good responses from students as evidenced by the evaluation results of 25 children getting an average score of 86,8%. Suggestions for further research are to develop learning media better, in terms of appearance, shape and how to use it, so that it is even more practical. The guidebook can be designed in more detail. The marble media can be replaced with other media to make its use more practical

Memaksimalkan keterampilan berpikir kritis menggunakan model problem heads review horay

Permasalahan pada penelitian ini adalah siswa masih kurang memahami materi pelajaran PPKn, siswa kurang aktif dalam mengikuti kegiatan pembelajaran di kelas, dan siswa juga kurang mampu menyelesaikan soal-soal berbasis masalah. Upaya untuk mengatasi permasalahan tersebut adalah dengan menerapkan model pembelajaran Problem Based Learning dengan kombinasi model Heads Review Horay (Numbered Heads Together, dan Course Review Horay) dalam kegiatan pembelajaran. Tujuan dari penelitian ini adalah untuk menganalisis keterampilan berpikir kritis siswa. Sedangkan, analisis data menggunakan Penelitian Tindakan Kelas (PTK). Temuan ini menunjukkan keterampilan berpikir kritis siswa mencapai kriteria kritis. Dapat disimpulkan bahwa pembelajaran menggunakan model pembelajaran Problem Based Learning dengan kombinasi model Heads Review Horay dapat meningkatkan aktivitas, dan keterampilan berpikir kritis

Mencetak Generasi yang Berakhlak Mulia: Perspektif Pendidikan dalam Tafsir al-Mishbah dan Tafsir al-Azhar pada Q.S. As-Saffat Ayat 100-111

Al-Qur’an Surah As-Saffat Verse 100-111 shows that Islamic teachings are very concerned about how important it is to create a generation that has noble character and is close to their Lord. This illustrates that the content of the verse has an educational perspective. However, in order not to leave the spirits of Islamic education, it is necessary to put the thoughts of the scholars into one of their works, including the interpretation of the Qur’an. This article concludes: First, the educational perspectives contained in the interpretation of al-Mishbah are: 1) Religious values, namely belief in God, divine guidance, trials, tawakkal, patience, piety, and the fruit of faith; 2) Social values, namely honest, democratic, and polite; 3) Ethical values, namely responsibility, hard work, and resilience; and 4) Aesthetic Values, namely appreciating achievements, giving values and awards. Second, the educational perspective contained in the interpretation of al-Azhar are: 1) Religious values, namely belief in God, divine guidance, trials, patience, tawakkal, syaja’ah (courage) and piety; 2) Ethical values, namely hard work, the fruit of faith; and 3) Aesthetic Values, namely appreciating achievements and giving values and awards. Third, the educational perspective contained in the two interpretations is understood from almost the same substance, the difference only lies in the narrative

PENGARUH PENAMBAHAN BERBAGAI JENIS SUSU TERHADAP KADAR ASAM LAKTAT PADA PEMBUATAN SUSU PREBIOTIK UBI JALAR (Ipomoea batatas L) OLEH BAKTERI Lactobacillus bulgaricus MENGGUNAKAN AUTOKLAF (The Effect of Additional Types of Milk to Lactic Acid Levels in The Making for Prebiotic Milk Sweet Potato by Lactobacillus bulgaricus Using The Autoclave)

Development of sweet potato processing (Ipomoea batatas L) as a food ingredient is now more rapidly one of which is processed as prebiotic milk that has high nutritional value as done in this research. This research aims to examine the effect of milk addition on lactic acid levels in prebiotic milk of sweet potato. Prebiotic filtrates sweet potatoes obtained by means of sweet potatoes steamed and crushed using a blender which then given the addition of 5% of sucrose. There are 3 treatments of milk addition to 3 types of sweet potato prebiotics (purple sweet potato, white sweet potato and yellow sweet potato) is without adding milk, the addition of sweetened condensed milk and the addition of full cream milk to each type of sweet potato. Prebiotic sweet potato milk is sterilized on autoclave using 121 ° C for 15 minutes. An autoclave is a tool used to sterilize various materials and devices in the microbiological world using pressurized steam. Observations made in this research is the measurement of lactic acid levels affected by Lactobacillus bulgaricus bacteria on 9 variables produced. Prebiotic purple sweet potato milk is superior prebiotic milk with higher lactic acid content than prebiotic milk of white and yellow sweet potatoes. Variable 2 is purple sweet potato prebiotic milk with the addition of sweetened condensed milk is the optimum variable which has the highest lactic acid content that is equal to 0,023%. Keywords : Autoclave, Lactat Acid, Lactobacillus bulgaricus, Prebiotic Milk Sweet Potat

IMPLEMENTASI LOGIKA FUZZY MAMDANI UNTUK PERAMALAN BEBAN LISTRIK JANGKA PENDEK PERUSAHAAN LISTRIK NEGARA (PLN) RAYON BANDA ACEH

Kebutuhan listrik di era teknologi saat ini sangat penting. Akibatnya semakin tinggi kebutuhan beban listrik yang dibutuhkan semakin besar pula energi listrik yang harus disediakan Perusahaan Listrik Negara (PLN). Untuk itu diperlukan peramalan beban listrik, agar beban listrik yang dihasilkan sesuai dengan kebutuhan. Penelitian ini bertujuan untuk meramalkan beban listrik jangka pendek dengan waktu ramalan 24 jam kedepan pada PLN Rayon Banda Aceh khususnya penyulang UNSYIAH, dengan suhu permukaan bumi dan beban listrik sebagai variabel prediktor. Peramalan menggunakan Fuzzy Inference System (FIS) Mamdani dengan membandingkan antar-lima metode defuzifikasi pada metode Mamdani yaitu centroid, bisektor, Mean of Maximum (MoM), Largest of Maximum (LoM), dan Smallest of Maximum (SoM). Dari hasil penelitian yang dilakukan, peramalan beban listrik pada tanggal 6 Mei 2015 menggunakan metode defuzifikasi pada metode Mamdani diperoleh hasil ramalan terbaik menggunakan metode defuzifikasi Bisektor dengan perhitungan Mean Absolute Percentage Error (MAPE) sebesar 4.62% dibandingkan dengan data aktual. Kata kunci: Peramalan beban listrik, Fuzzy Inference System (FIS) Mamdani, metode defuzifikasi
