Abstract

Arbuscular mycorrhizal fungi (AMF) belong to endomycorrhizae and are symbiotic with nearly 90% of plants. Studies on the diversity of AMF with the Duabanga tree species (Duabanga moluccana Blume.) Have not been widely reported. This study aims to determine the diversity of arbuscular mycorrhizal fungi (AMF) in Duabanga plants in Konda District, Konawe Selatan Regency. Soil and plant root samples were taken in Konda District, Konawe Selatan Regency, Southeast Sulawesi Province. Observations of root colonization, isolation and identification of AMF were carried out at the plastic house of the Indonesian Mycorrhizal Association (AMI) Southeast Sulawesi Branch, Kendari City, Southeast Sulawesi Province, for 4 months. The results showed that the two dwarf plants were colonized by AMF. The types of AMF found were 5 types of spores from the genus Glomus. The AMF structures found are internal hyphae, external hyphae and vesicles. The diversity of AMF is in the low category.

Abstract

Penanganan benih jabon merah oleh pengelola persemaian permanen Anduna, Konawe Selatan, Sulawesi Tenggara masih terbatas. Oleh karena itu, perlu upaya peningkatan pengetahuan para pengelola melalui bimbingan teknis. Tujuan pelaksanaan bimbingan teknis adalah untuk meningkatkan pengetahuan dan kapasitas pengelola persemaian permanen tentang ekstraksi dan perkecambahan benih jabon merah. Bimtek ini telah dilaksanakan pada tanggal 11 Mei 2024 bertempat di Persemaian permanen Anduna, Konawe Selatan dengan jumlah peserta 30 orang. Metode yang digunakan dalam program ini adalah metode Technology Transfer. Hasil pengabdian menunjukkan bahwa terjadi peningkatan pengetahuan dan kapasitas pengelola persemaian terkait pengenalan jabon merah, teknik ekstraksi dan perkecambahan benih jabon merah. Selain itu, tersedia benih jabon merah untuk kebutuhan produksi bibit jabon merah di persemaian permanen BPDAS Sampara.han produksi bibit jabon merah di persemaian permanen BPDAS Sampara.Abstarct. Handling of red jabon seedlings by managers of the Anduna permanent nursery, South Konawe, Southeast Sulawesi is still limited. Therefore, efforts are needed to increase managers' knowledge through technical guidance. The aim of implementing technical guidance is to increase the knowledge and capacity of permanent nursery managers regarding extraction and germination of red jabon seeds. This technical guidance was carried out on 11 May 2024 at the Anduna permanent nursery, South Konawe with a total of 30 participants. The method used in this program is the Technology Transfer method. The results of the service show an increase in the knowledge and capacity of nursery managers regarding the introduction of red jabon, extraction techniques and germination of red jabon seeds. Apart from that, red jabon seeds are also available for the production of red jabon seedlings at the BPDAS Sampara permanent nursery.

Abstract

This study analyzes the variation of infiltration rates across different land-use types in the upper watershed of the Jompi River Basin, Muna Regency, as an effort to understand hydrological responses to land-use change. Forest ecosystems play a crucial role in regulating water balance through enhanced soil porosity and organic matter accumulation, whereas land conversion often reduces infiltration capacity and increases surface runoff. Using a quantitative cross-sectional design, field measurements were conducted from August to October 2023 on four dominant land-use categories forest, agriculture, plantation, and settlement. Infiltration was measured using a double ring infiltrometer, while soil physical properties were analyzed through laboratory testing. The results indicate substantial variation in infiltration rates: plantations recorded the highest average value at 24.23 cm/hour, followed by secondary forest at 22.38 cm/hour, settlements at 19.23 cm/hour, and agricultural land at 16.59 cm/hour. These differences are strongly influenced by soil texture, organic matter, and porosity conditions. The findings demonstrate that land-use changes significantly alter soil hydrological behavior, highlighting the need for sustainable watershed management strategies. Further research is recommended to incorporate additional soil parameters such as permeability and to employ alternative infiltration models and rainfall simulators for improved measurement accuracy
