Abstract

This study evaluated the chemical status of soils under maize (Zea mays L.) cultivation in Tibawa Subdistrict, Gorontalo Regency, Indonesia, to identify fertility constraints and inform site-specific management. A field survey was conducted in May 2025 at three villages (Isimu Utara, Datahu, and Iloponu). At each site, ten subsamples from the 0–20 cm plough layer were composited and analysed for soil pH (H2O and KCl), organic carbon, total nitrogen (Kjeldahl), available phosphorus (Bray I), exchangeable potassium (NH4OAc), and cation exchange capacity (CEC). Results indicated slightly acidic to neutral soils (pH 6.3 - 6.9) with moderate CEC (16.72 - 22.32 cmol(+)/kg). Organic carbon ranged from low to moderate (1.42 - 2.51%). Available P was consistently moderate (12.04–14.72 ppm), whereas exchangeable K was low across all sites (0.19 - 0.24 cmol(+)/kg). Total N varied from low in Isimu Utara (0.13%) to moderate in Datahu and Iloponu (0.24 - 0.26%). The primary limitations for maize production were low K availability and, locally, low N and organic matter. Management should prioritize organic amendments, balanced NPK fertilization based on soil testing, and periodic liming where acidification trends emerge. These findings provide a baseline for future monitoring of soil quality and developing recommendations to sustain maize yields while reducing nutrient losses under intensive management in Tibawa.

Abstract

Pengabdian ini bertujuan untuk meningkatkan pemahaman masyarakat mengenai pengelolaan sampah melalui edukasi berbasis pengetahuan durasi dekomposisi berbagai jenis sampah. Kegiatan dilaksanakan dengan pendekatan edukatif melalui sosialisasi, penyuluhan, dan pendampingan terkait pemilahan serta pengolahan sampah organik dan anorganik. Metode pelaksanaan meliputi tahap persiapan, pelaksanaan edukasi, dan evaluasi pemahaman masyarakat. Materi yang disampaikan mencakup perbedaan waktu dekomposisi sampah, faktor-faktor yang memengaruhi proses dekomposisi, serta penerapan prinsip 4R (Reduce, Reuse, Recycle, dan Replace). Hasil pengabdian menunjukkan adanya peningkatan pemahaman masyarakat terkait pentingnya pemilahan sampah dan dampak lingkungan dari sampah yang sulit terurai. Masyarakat mulai memahami bahwa sampah organik dapat terurai dalam waktu relatif singkat, yaitu dalam hitungan minggu hingga bulan, sedangkan sampah anorganik seperti plastik dan kaca membutuhkan waktu puluhan hingga ribuan tahun untuk terurai. Selain itu, kegiatan ini mendorong perubahan perilaku masyarakat dalam pengelolaan sampah rumah tangga, seperti mulai melakukan pemilahan sampah dan pengomposan sederhana. Dengan demikian, edukasi berbasis durasi dekomposisi sampah efektif dalam meningkatkan kesadaran dan partisipasi masyarakat dalam pengelolaan lingkungan yang berkelanjutan.

Abstract

Outing class is a fun teaching and learning activity. This learning activity can be said to be fun because playing is voluntary and creates a sense of enjoyment for students. Through play, learning activities that initially felt boring for students transform into enjoyable learning activities through play. Teaching and learning activities are not conducted indoors as is usually the case, but rather outdoors. This activity brings students closer to their environment. This research used a quantitative research with a Pre-Experimental Design with a One Group Pre-Test and Post-Test Design. The population consisted of five classes, and sampling was carried out using a purposive sampling technique. The sample was class XE 2 of SMAN 7 SMAN 7 BONE, with 26 students. Data collection techniques used in this study included providing pre- and post-test sheets to assess students' conceptual understanding and documentation. Based on the results of the research, it can be concluded that the outing class method has an effect on students' environmental awareness. Data management showed that the average pre-test score was 62 and the average post-test score was 84.42. The SPSS analysis results show a significance value of 0.000, which is less than 0.05, indicating that the use of the outing class method as a learning resource is effective in improving students' environmental awareness.
