Abstract

Pendidikan karakter bertujuan untuk membentuk individu yang tidak hanya unggul secara intelektual, tetapi juga memiliki nilai-nilai seperti integritas, tanggung jawab, dan empati. Namun, penerapan pendidikan karakter terhadap Gen Z menghadapi berbagai tantangan. Salah satunya adalah kesenjangan antara nilai-nilai tradisional dan pengaruh budaya digital yang sering kali mendorong perilaku individualistis dan instan. Selain itu, paparan konten digital yang beragam dan tidak selalu positif dapat memengaruhi perkembangan karakter generasi ini. Penelitian ini bertujuan untuk mengetahui tantangan pendidikan karakter terhadap Gen Z melalui pendekatan geografi. Metode yang digunakan pada penelitian ini adalah library research (studi literatur) yang kemudian dianalisis dengan pendekatan deskriptif. Hasil penelitian menemukan bahwa untuk melaksanakan pendidikan karakter pada Gen Z perlu melibatkan upaya bersama dari berbagai komponen seperti keluarga, sekolah, dan masyarakat. Mata pelajaran geografi dapat menjadi salah satu pendekatan untuk menerapkan pendidikan karakter karena mempelajari tentang alam, manusia, serta interaksi timbal balik di antara keduanya. Melalui pendidikan karakter yang baik, diharapkan perkembangan teknologi dapat dimanfaatkan untuk menghadapi tantangan dan memanfaatkan peluang yang ada.

Abstract

This study aims to investigate the effect of pH variations and collector types on the recovery efficiency and Cu content in copper sulfide mineral samples. The experiment was conducted by varying the pH (6, 8, 10, and 12) and using different types of collectors, namely Xanthate, Potassium Amyl Xanthate (PAX), Diethyl Dithiophosphate (DTP), and a combination of PAX + DTP. Control variables included flotation time (5, 10, 15, 20, and 25 minutes), collector concentration at 50 mg/L, particle size <75 µm, and the use of Frother Methyl Isobutyl Carbinol (MIBC) at a concentration of 10 mg/L. Modifiers such as NaOH and H₂SO₄ were used to adjust the pH, while Copper Sulfate (CuSO₄) served as an activator and Sodium Metabisulfite (Na₂S₂O₅) as a depressant. The results showed that variations in pH and collector types significantly influenced recovery efficiency and Cu content in the concentrate. In general, the highest recovery efficiency was achieved at pH 10 with the combination of PAX + DTP, which resulted in a higher Cu content compared to other single collectors. This combination was able to improve recovery efficiency to over 75%, with Cu content in the concentrate reaching 28%. Therefore, the findings suggest the use of a collector combination and pH optimization as strategies to enhance the performance of copper sulfide flotation.

Abstract

Tidak adanya minat, komitmen, dan pemahaman dari berbagai pihak terkait seperti guru, orang tua, dan peserta didik sering menyebabkan sekolah tidak berkarakter. Banyak sekolah menemukan bahwa mereka tidak memiliki pendekatan yang sesuai dengan nilai-nilai karakter yang diinginkan, yang menyebabkan ketidakjelasan dalam penerapannya. Tujuan pada penelitian ini adalah untuk merumuskan dan mengidetifikasi bagaimana strategi menciptakan sekolah yang berkarakter di Indonesia. Hal ini sangat penting karena sistem Pendidikan yang di terapkan di Indonesia belum mampu secara efektif dalam menanamkan nilai-nilai karakter pada peserta didik. Teknik analisis data yang digunakan dalam penelitian ini meliputi pengumpulan data dengan cara menganalisis dan mengidentifikasi konten dari berbagai sumber yang berhubungan dengan “Menciptakan sekolah berkarakter.” Proses pengumpulan data yang dilakukan melalui Teknik dokumentasi, yang mencakup membaca text reading, dengan cara mengkaji, mempelajari dan mencatat literatur yang relevan. Hasil dari penelitian ini menujukkan bahwa menciptakan sekolah berkarakter harus menjadi bagian intregral dari kurikulum sekolah. Sekolah sangat wajib dan perlu menerapkan Pendidikan berkarakter yang bermoral secara praktis dan mengembangkan figur teladan di kalangan guru dan peserta didik. Selain itu, penting juga melibatkan masyarakat dan keluarga dalam proses menciptakan sekolah berkarakter, sehingga Pendidikan yang berdasarkan karakter dapat berjalan efektif dan berkelanjutan. Dengan kata lain Pendidikan karakter yang ada disekolah mampu membangun peserta didik yang berkualitas dan dapat mengurangi perilaku negatif terhadap peserta didik.

Abstract

Effective geography education requires instructional media capable of visualizing spatial phenomena in a realistic and interactive manner. Google Earth, a digital mapping application based on satellite imagery and geospatial data, offers an innovative approach to address this need. This study aims to examineimplementation and advantages of Google Earth as a contextual learning medium in geography education through a systematic literature review. The analysis reveals that Google Earth significantly enhances students’ comprehension of key geographical concepts, including absolute and relative location, spatial distribution, spatial interaction, and regional dynamics, through 3D visualizations and geospatial data exploration. Furthermore, its integration supports project-based and inquiry-based learning models aligned with the Merdeka Curriculum. However, several challenges hinder its implementation, such as limited technological infrastructure, low digital literacy among educators and learners, and various technical issues. To fully leverage the potential of Google Earth in geography instruction, strategic implementation planning, teacher training, and institutional support are essential.

Abstract

This study aims to evaluate the implementation of differentiated instruction in Chemistry subject for Grade 10 students across senior high schools in Gorontalo City using Stake’s Countenance Model. The evaluation focused on three key components: antecedent (lesson planning), transaction (instructional implementation), and outcome (student learning results). Data were collected through the analysis of lesson plans and teaching modules, classroom observations, teacher interviews, and assessments of student learning outcomes. The analysis employed both congruence and contingency approaches. The findings indicate that both lesson planning and instructional implementation fall into the "moderate" category, with average scores of 69.82% and 67.52%, respectively, while student learning outcomes were categorized as "good" with an average score of 68.89%. The contingency analysis revealed a misalignment between antecedent and transaction with the outcome, suggesting that student achievement was more strongly influenced by administrative targets (KKTP) rather than the effectiveness of differentiated instruction strategies. This study recommends the need for pedagogical training focused on strengthening conceptual understanding of differentiation, designing adaptive instructional materials, and applying authentic assessment practices to promote inclusive and responsive learning tailored to diverse student needs.
