Abstract

Even though phytoremediation is considered a green technology for remediating heavy metals, there are some problems with the application of this technology, particularly when it comes to managing the biomass that is used. So, processing biomass needs to be given a lot of attention. This study outlined the utilization of extracts obtained from the hyperaccumulator plant Brassica oleracea var. alboglabra to synthesize nickel oxide nanoparticles. Subsequently, the nanoparticle underwent testing to determine its suitability as an absorbent for heavy metals, specifically lead, as well as its efficacy as an antifungal agent against Fusarium sp. strain. The characterization of nickel oxide nanoparticles involved several measurements, such as scanning electron microscopy analysis, high- and low-resolution transmission electron microscopy, energy dispersive spectroscopy, X-ray diffraction, and hysteresis curve acquisition. The research findings indicate that the extract from hyperaccumulators can be utilized for the synthesis of NiO, which exhibits an absorption capacity exceeding 98% and serves as an efficient antifungal agent against Fusarium sp. pathogens. The approach utilized in this study not only prioritizes "green" and sustainability factors but also takes into account the economic aspects associated with the items being manufactured. The research has important implications in two areas. Firstly, it demonstrates the utilization of natural resources (B. oleracea var. alboglabra) in the production of nickel oxide, which serves as a safer and more eco-friendly substitute for dangerous chemicals. Furthermore, it aids in the advancement of novel techniques for effectively managing biomass hyperaccumulators.

Abstract

The formation of student character through habituation and example can be the basic capital for character building in Islamic educational institutions. With this habituation and example, students get real examples where they study. This study aims to describe the character formation of students through habituation and example of teachers at MIN 1 Minahasa. This study used descriptive qualitative method. The results showed that the formation of student character through habituation at MIN 1 Minahasa was carried out by habituation in carrying out the dhuha prayer, greeting parents, teachers, older siblings, and peers. Students are accustomed to wearing uniforms, memorizing short verses and Asmaul Husna, the attributes of Allah, and getting used to reading prayers before and after the lesson begins and ends. Meanwhile, character building through the example of teachers is carried out by providing advice related to character education during the implementation of the morning apple, the learning process, and students' daily activities at school.

Abstract

Masyarakat pesisir di Sindulang Dua sangatlah majemuk, dengan kuantitas muslim sebagai minoritas dan tingkat ekonomi berada pada level pra sejahtera, akibatnya muncul berbagai problem sosial-keagamaan seperti lemahnya pengetahuan agama sehingga ada beberapa yang keluar dari Islam, terjadi kekerasan dalam rumahtangga hingga berdampak pada perceraian dan broken home pada anak, bahkan terjadi kriminalitas di wilayah setempat karena faktor kebutuhan ekonomi. Inilah urgensi dilakukannya pengabdian kepada masyarakat di wilayah tersebut dengan fokus pembinaan keluarga bahagia, tahsin al-Qur'an, perbaikan arah kiblat, dan pembinaan ekonomi syari'ah. Metode yang dilakukan adalah penyuluhan, pelatihan, dan pendampingan kepada selupuh orang peserta aktif, dengan pendekatan Asset-Based Community Development. Hasilnya dari sepuluh orang peserta tersebut; mampu memahami dengan baik beberapa norma tentang hak dan kewajiban dalam rumahtangga beserta implikasinya; memahmi dan mempraktikkan kembali tahsin al-Qur'an; perbaikan arah kiblat Musholla Al-Huda berdasarkan ilmu falak dan teknologi modern; dan penyuluhan tentang praktik ekonomi syari'ah beserta pelatihan memproduksi abon cakalang yang halal lagi baik.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh lingkungan sekolah terhadap pembentukan karakter siswa muslim dan kristen di SMPN 1 Modayag Kecamatan Modayag. Jenis penelitian yang digunakan dalam penelitian ini adalah eksplanatory dengan pendekatakan kuantitatif, di mana penelitian ini bermaksud unutk mengetahui apakah terdapat hubungan sebab-akibat antara dua fenomena yang terpisah. Penelitian ini menggunakan teknik analisis regresi linear sederhana. Sampel pada penelitian ini sebanyak 125 siswa. Metode pengumpulan data menggunakan angket untuk mengukur variabel lingkungan sekolah dan variabel pembentukan karakter siswa.Hasil dari penelitian ini adalah lingkungan sekolah berpengaruh positif dan signifikan terhadap pembentukan karakter siswa muslim dan kristen di SMPN 1 Modayag Kecamatan Modayag. Hal ini dapat dijelaskan dengan nilai Fhitung > Ftabel yaitu 154,999 > 3,92 atau bisa juga dilihat dari taraf signifikan 0,000 < 0,05 yang artinya H0 ditolak. Hasil persamaan regresi linear sederhana adalah: Ŷ = 26,521 + 0,708X, yang menunjukan bahwa nilai koefisisen X sebesar 0,708 yang artinya bahwa jika nilai lingkungan sekolah nilainya bertambah 1 skor maka pembentukan karakter siswa akan bertambah sebesar 0,708. Sehingga dapat dikatakan bahwa terciptanya lingkungan sekolah yang mempunyai relasi guru dan siswa yang baik, relasi siswa dan siswa yang kondusif, dan tata tertib yang ditegakkan secara teratur dan konsisten akan membentuk karakter siswa yang disiplin, jujur, dan toleran. Kata kunci: Lingkungan, Sekolah, Pembentukan Karakter

Abstract

The lack of integration between research-based learning and character education remains a major challenge in Islamic higher education today, where students are required to master 21st-century skills while also developing strong character and academic integrity. This study aims to develop a Research-Based Learning model integrated with Character Education (RBL-ICE) and its associated instructional devices for the Basic Science course. The study employed a Research and Development (R&D) approach with the 4D model (define, design, develop, disseminate). The population comprised all Madrasah Ibtidaiyah (MI) pre-service teachers enrolled in the Basic Science course at IAIN Manado. The sample consisted of 15 students selected through purposive sampling. The measured variables included learning outcomes, learning motivation, and student character. Learning outcomes were obtained through pretest and posttest, learning motivation was measured using a questionnaire based on the ARCS model, and character was assessed using observation sheets. The validity of the model and instructional devices was evaluated by two material experts and two media experts. The material experts rated the research instruments, lesson plans, teaching materials, and student worksheets as very feasible, while the media experts rated the student worksheets and teaching materials as very feasible. Learning outcomes data were analyzed using prerequisite tests (normality) and hypothesis testing with a paired sample t-test, whereas motivation and character were analyzed descriptively. The implementation of the RBL-ICE model improved students’ learning outcomes, with an average pretest score of 66.67 and posttest score of 77.07, and an N-gain of 0.3271 (moderate category), accompanied by increased motivation and character in the positive category. These findings indicate that the RBL-ICE model is effective in enhancing the learning outcomes, motivation, and character of prospective MI teachers in the Basic Science course at IAIN Manado.

Abstract

The program aims to foster students’ eco-theological awareness through tree-planting activities as a form of responsibility toward God’s creation, while also creating a green, healthy, and spiritually enriched school environment. The activity took place at Al-Faqih Foundation Kauditan, North Minahasa, on September 18, 2025, involving the foundation board, school leaders, teachers, and students in a spirit of collaboration to care for the environment. The program included several stages: planning, socialization and education, tree planting, as well as evaluation and reflection to strengthen understanding and participation among all stakeholders. The results showed a significant increase in environmental awareness, with about 80% of students actively participating in the planting activities and 90% of teachers supporting the ongoing initiatives. Through the planting of 75 tree seedlings around the school area, the learning atmosphere has become greener, fresher, and more enriched with educational and spiritual values. This program is designed to be sustainable, with regular tree maintenance and continued student involvement in environmental activities to nurture spiritual awareness and ecological responsibility as part of daily school life.
