Abstract

Human activities in seeking agricultural lands, has change the traditional agricultural system into intensive cultivation system. One effort to minimize intensive agriculture system is the use of natural enemies to control pests. Habitat management should be implemented by creating habitat favored by natural enemies. This research aims to determine the spatial and temporal distribution of natural enemies of wild plants: Mimosa pudica, Vernonia cinera, Marsilea crenata, and Pistia startiotes on agricultural land. This research was conducted in March-April 2010 in Malang Sawojajar farmland. Plants placed in the corner field (refugia areas), visiting insects was observed starting from refugia areas and two meters away from the refugia area. Observations of insect use the "visual control" metode. The results showed that natural enemies visiting to the refugia areas were 6 orders (15 families): Coleoptera, Odonata, Aaraneae, Hymenoptera, Diptera, and Orthoptera. Not all natural enemies have spatial and temporal distribution, only 9 families who indicate a pattern spatial or and temporal distribution. Overall, natural enemies do not show any significant spatial pattern (F> 0.05), but indicate a temporal pattern (F

Abstract

Gumuk is a unique landscape in Jember Regency resulting from the eruption of Mount Raung that can provide ecosystem services through its ecological functions. Increased mining activity in Gumuk and land-use changes can lead to a decline in biodiversity and affect ecosystem services. This study aims to determine the diversity of herbaceous in the Gumuk ecosystem. Conducted in January - March 2021 in Ledokombo District, Jember Regency. The spatial distribution of Gumuk was carried out using GIS. Herbaceous sampling was carried out using 2x2 plots on three types of Gumuk utilisation, namely mixed gardens, sand mining, and stone mining. The results showed that there were 136 Gumuk in Ledokombo District. One hundred twenty herbaceous species (49 families) were found in all types of Gumuk. Mixed gardens have the highest species diversity (109 species, 49 families) compared to other types. Digitaria sanguinalis (L.) Scop. has high dominance in all types. Species dominance showed a moderate category for all types of Gumuk (D = 0.07). Community complexity in all types was in the high class (D' = 0.90) and species diversity was in the high class (H’ = 3.25). Evenness index € was different in the three types of Gumuk; in mixed gardens, the evenness of species was lower (0.23) than the other two types.

Abstract

Penelitian ini bertujuan untuk mendeskripsikan problematika penerapan Kurikulum Merdeka dalam pembelajaran Biologi kelas X di MA At-Taqwa Suren Jember tahun pelajaran 2024/2025. Penelitian ini menggunakan metode kualitatif deskriptif dengan teknik pengumpulan data berupa observasi, wawancara, dan dokumentasi. Analisis data yang digunakan dalam penelitian terdiri dari kondensasi data, penyajian data, dan penarikan kesimpulan. Hasil penelitian menunjukkan bahwa penerapan kurikulum merdeka berjalan efektif dan sistematis melalui dokumen kurikulum, metode ajar berbasis sains, bahan ajar, media ajar, serta sumber pembelajaran yang sesuai karakteristik siswa. Kendala utama yang dihadapi adalah keterbatasan sarana, prasarana, dan sumber belajar yang masih minim, sehingga kurang menunjang proses pembelajaran. Faktor pendukung utama adalah upaya guru dalam memanfaatkan media pembelajaran alternatif agar siswa tetap aktif dalam pembelajaran.
