Abstract

Petani holtikultura di Desa Nagori Urung Purba perlu melakukan efisiensi dalam penggunaan pupuk organic. Hal ini untuk menjaga keberlanjutan produkstivitas pertanian serta keberlanjutan dalam menjaga kesuburan lahan pertanian. Rangkaian pelaksanaan kegiatan yaitu pada tahap pertama adalah pemberian materi mengenai efisiensi pupuk organic dalam pertanian, penyuluhan pupuk organic dan pelatihan pembuatan pupuk organik (pengomposan) kepada kelompok sasaran yakni Petani di Desa Nagori Urung Purba. Untuk membuat pupuk kompos organik ini dengan memanfaatkan limbah sisa gulma, kompos kohe sapi, tanah humus dari lingkungan sekitar. petani mendapat arahan mengenai pembuatan pupuk organic yang efisien sehingga diharapkan pupuk organic ini dapat dimanfaatkan oleh petani dalam efisiaensi penggunaan modal terutama untuk alokasi pembelian pupuk sintetis.

Abstract

Abstract: This study aims to develop students' social and cognitive skills at Harford Institute through the Mapping Concept method. The research adopts a qualitative descriptive approach with a sample of 13 students selected using total sampling technique. Instruments such as questionnaires and tests were employed to assess social skills (communication, collaboration, and empathy) and cognitive skills (problem-solving, critical thinking, and knowledge organization). The results indicate that the Mapping Concept method effectively enhances students' social skills, especially in group discussions, and cognitive skills, such as understanding material. In conclusion, this method significantly contributes to a more inclusive and collaborative learning experience and can be widely applied in educational environments.Keywords: Social Skills, Cognitive Skills, and Concept Mapping Abstrak: Penelitian ini bertujuan untuk mengembangkan keterampilan sosial dan kognitif siswa di Harford Institute melalui metode Mapping Concept. Penelitian menggunakan pendekatan deskriptif kualitatif dengan sampel sebanyak 13 siswa yang dipilih menggunakan teknik total sampling. Instrumen berupa angket dan tes digunakan untuk mengukur keterampilan sosial (komunikasi, kerja sama, dan empati) serta kognitif (pemecahan masalah, berpikir kritis, dan pengorganisasian pengetahuan). Hasil analisis menunjukkan bahwa metode Mapping Concept efektif meningkatkan keterampilan sosial siswa, terutama dalam diskusi kelompok, dan keterampilan kognitif, seperti pemahaman materi. Kesimpulannya, metode ini memberikan kontribusi signifikan terhadap pengalaman belajar yang lebih inklusif dan kolaboratif, sehingga dapat diterapkan secara lebih luas dalam lingkungan pendidikan.Kata kunci: Keterampilan Sosial, Keterampilan Kogniti, dan Mapping Concept

Abstract

The purpose of this study is to investigate the morphophysiological characteristics of teak plants (Tectona grandis) in Sarinembah Village, Karo Regency. The research method employed in this study is a survey method, focusing on identifying the morphological characteristics of teak plants in Sarinembah Village, Karo Regency, and North Sumatra Province. The study explores the morphological characteristics of teak plants, including leaf color, leaf shape, leaf tip, leaf base, leaf edge, leaf surface texture, leaf vein pattern, height, and diameter of teak trees. The results show variation in leaf color depending on the position on the tree, with leaves typically being elliptical or inverted egg-shaped, pointed at the tip and base with flat edges, rough surface texture, and reticulate leaf veins. Additionally, the height and diameter of teak trees vary, influenced by genetic factors affecting tree growth.
