Abstract

Root isolation activities to obtain dark septate endophytic fungi are currently mostly carried out on agricultural and plantation crops, while less so on forestry crops. Roots are a suitable habitat for the growth of various microorganisms, including dark septate endophytic fungi. The research aims to isolate the roots of Pinus merkusii plants from four locations, test pathogenicity, and test the biomass of sweet caisim mustard seeds. The research used a descriptive method by observing the number of dark septate endophytic fungal isolates obtained and the pathogenicity of these isolates. Meanwhile, sweet ciasim mustard seed biomass from the pathogenicity test results of non-pathogenic isolates was analyzed using a completely randomized design. The results of root isolation from Pinus merkusii stands obtained as many as 25 isolates by isolating 1,160 root segments. Isolation of Pinus merkusii roots from the IPB Dramaga Campus obtained 16 isolates, Dabun Gelang Village, Gayo Lues Regency obtained 2 isolates, Gunung Walat University Forest obtained 2 isolates, and Gunung Halimun Salak National Park obtained 5 isolates. Pathogenicity tests showed that 12 isolates were pathogenic and 13 isolates were non-pathogenic. Biomass analysis of sweet ciasim mustard seeds on non-pathogenic isolates obtained the highest biomass in the control treatment (not inoculated) and the lowest in isolates Apg 23.5 and Hs 14.6b. There is still a lack of isolates obtained from isolation activities in this research, so it is necessary to find an appropriate sterilization method to obtain the maximum number of isolates and have the potential to become non-pathogenic isolates.

Abstract

Limbah kotoran ternak unggas merupakan salah satu sumber pencemaran lingkungan apabila tidak dikelola dengan baik. Melalui program pengabdian ini dilakukan edukasi dan pelatihan mengolah limbah kotoran ternak menjadi pupuk organik. Pengabdian ini bertujuan untuk mengoptimalkan pemanfaatan limbah peternakan unggas menggunakan mikroorganisme menjadi produk bernilai ekonomis dan ramah lingkungan, yaitu dengan pembuatan pupuk organik. Kegiatan ini dilaksanakan di Universitas Teuku Umar, Kabupaten Aceh Barat, dengan melibatkan dosen dan mahasiswa. Metode pelaksanaan meliputi sosialisasi, pelatihan pembuatan pupuk organik berbasis mikroba, serta pendampingan teknis. Kegiatan ini berdampak positif terhadap pemahaman dan keterampilan peserta dalam mengelola limbah secara mandiri serta potensi peningkatan pendapatan peternak. Program ini diharapkan dapat menjadi solusi berkelanjutan dalam pengelolaan limbah peternakan dan peningkatan kesejahteraan masyarakat.

Abstract

Arabica coffee is one of the world's leading coffee species that grows optimally in tropical highland areas, such as Central Aceh, and is often cultivated in agroforestry systems. Coffee agroforestry not only increases agricultural productivity but also plays a vital role in carbon sequestration and environmental conservation through the presence of shade trees that store carbon in biomass. This system is globally recognized as a climate change mitigation strategy and supports ecological balance. These places are included in the 568 ha Social Forestry area, has great potential for sustainable coffee agroforestry development. This study aims to analyze the potential carbon stocks and carbon dioxide (CO₂) absorption in the Social Forestry area of Kekuyang Village, Central Aceh Regency. Data were collected using a vegetation inventory method in 28 observation plots measuring 20 m × 20 m. Tree diameter data were used to calculate biomass using allometric equations, which were then converted into carbon stocks and CO₂ absorption. The results showed a total aboveground biomass (AGB) of 55,439.20 kg, with an estimated carbon stock of 26,135.74 kg from the total area of the research plot. The potential for carbon dioxide absorption reached 85.64 tons/ha after conversion. The plant species with the largest contribution to carbon stocks was lamtoro (Leucaena leucocephala), followed by avocado (Persea americana) and Arabica coffee (Coffea arabica). The coffee agroforestry system in Kekuyang Village has proven to be ecologically effective in storing carbon and has the potential to become a model for sustainable land management that supports climate change mitigation.
