Abstract

Pepper is a plantation commodity that belongs to the spice category and has an important role in Indonesia's economic growth. Southeast Sulawesi is one of the centers for the development of pepper plants, especially in the South Konawe area. The purpose of this study was to determine the effect of indigenous mycorrhizae on the growth of pepper plants which were carried out in Sindangkasih Village, West Ranomeeto District, South Konawe Regency. Analysis of dry weight and infection of indigenous mycorrhizae on the roots of pepper plants was carried out at the Agrotechnology Laboratory, Faculty of Agriculture, University of Haluoleo Kendari. Data analysis in this study used a single factor Randomized Block Design (RBD) with 4 treatments and 3 replications, so there were 12 trials. The treatment consisted of 4 levels, namely without mycorrhizae (A0), 10 grams of mycorrhizae (A1), 15 grams of mycorrhizae (A2) and 20 grams of mycorrhizae (A3). The results showed that the application of indigenous arbuscular mycorrhizae had an effect on the growth parameters of pepper plants in the form of plant height, number of leaves and number of tendrils, where A3 produced higher plant height, number of leaves and number of tendrils and was significantly different from other treatments. Treatment A2 was not significantly different from treatment A1 but significantly different from treatment A0 (without mycorrhiza). Mycorrhizal inoculation of 20 grams/polybag can cause root infection of pepper plants to increase by 80.00%.

Abstract

Sampah plastik merupakan masalah besar, bukan hanya di Indonesia, tetapi di seluruh dunia. Pencemaran sampah plastik tidak hanya berdampak buruk terhadap lingkungan. Namun dapat menimbulkan dampak yang sangat berbahaya bagi biota laut. Mikroplastik yang tertelan oleh biota laut dapat menyebabkan gangguan metabolisme, iritasi sistem pencernaan bahkan menyebabkan kematian. Kandungan mikroplastik yang terakumulasi pada organisme laut dapat berpindah ke tubuh manusia melalui rantai makanan. Sampah plastik diyakini menjadi penyebab penyakit terumbu karang. Upaya pencegahan pencemaran sampah plastik harus dilakukan secara holistik dan melibatkan pastisipasi masyarakat. Salah satu upaya yang dapat dilakukan adalah sosialisasi mengenai dampak pencemaran sampah plastik terhadap biota laut dan kesehatan manusia kepada masyarakat pesisir. Tujuan kegiatan ini adalah meningkatkan pengetahuan dan kesadaran masyarakat tentang bahaya sampah plastik, sehingga dapat meningkatkan peran masyarakat dalam upaya pencegahan pencemaran sampah plastik dan pengelolaan lingkungan. Kegiatan ini melibatkan 17 orang mahasiswa dan dosen program studi pendidikan biologi, 15 orang mahasiswa peserta KKA dan diikuti oleh 37 orang warga desa Banabungi sebagai mitra. Kegiatan ini meliputi koordinasi, sosialisasi, aksi pengumpulan dan reduksi sampah dan evaluasi melalui quisioner. Hasil evaluasi menunjukkan pemahaman masyarakat meningkat sebesar 15,2%. Keberhasilan kegiatan juga terlihat pada partisipasi masyarakat dalam mengikuti kegiatan
