Abstract

Mount Semeru eruption in 2020 and 2021 damaged 851 ha of productive land. Restoration of the affected lands requires information such as wide area, distribution, and eruption material characteristics. This community service aimed to provide a database as an overview of pyroclastic materials characteristics and elucidate potential-and-adaptive plants and microbes on post-Mt. Semeru eruptions. The volcanic ash contains significant elements (Al, Si, K, Ca, Ti, and Fe) and minor elements (V, Cr, Mn, Cu, Zn, Sr, Ba, Eu, and Re). Some of the plants that have survived post-eruption are annual shrubs and herbaceous plants such as grasses, so these plants can be used to restore the affected lands fertility after the Mt Semeru eruption. Based on economic evaluation and conditions in the field, the recommended adaptive plants are Pennisetum puparium and Musa paradisiaca. Both plants provide economic benefits for animal feed and farmers' income during post-eruption land recovery.

Abstract

Sistem pertanian pada dataran tinggi mempunyai keunikan dan tantangan tersendiri, termasuk kawasan pertanian di Desa Wonokitri, Pasuruan, Jawa Timur. Kesesuain lahan untuk budidaya komoditas hortikultura menyebabkan praktek pertanian yang digunakan termasuk intensif melalui pengolahan tanah, pola tanam, penggunaan pupuk hingga pengendalian hama penyakit. Komoditas utama pada lahan ini adalah kentang, selain syarat tumbuh terpenuhi juga dikarenakan nilai jual kentang yang tinggi. Namun, yang menjadi tantangan adalah praktek penanaman dilakukan pada lahan berlereng dan tidak disertai dengan penerapan tindakan konservasi. Kegiatan pengabdian masyarakat ini bertujuan untuk mengembangkan pertanian koservasi yang berbasis kearifan lokal pada lahan berlereng di Desa Wonokitri, Pasuruan, Jawa Timur. Metode yang digunakan mencakup observasi lapangan, analisis tanah, dan Focus Group Discussion (FGD) dengan petani setempat. Sifat tanah di lahan pertanian wonokitri termasuk dalam tekstur lempung berdebu, berat isi tanah 0,62 g cm-3, porositas tinggi (> 50%), permeabilitas cepat (>12,7 cm jam-1) dan kemantapan agregat sangat stabil sekali (>2 mm), sehingga secara fisik sangat baik dalam menopang pertumbuhan tanaman kentang. Namun, sistem pertanian berlerang tanpa konservasi yang dilakukan sangat berpotensi menurunkan produktivitas lahan di masa mendatang. Oleh sebab itu, berdasarkan kondisi aktual lahan, kesesuaian tanaman dan sosial ekonomi dirumuskan tindakan konservasi yang dapat diterima yakni dengan penanaman pada bedengan searah lereng yang dilengkapi dengan saluran pengelak dan saluran pembuangan air (SPA) serta bak penampung untuk menangkap limpasan permukaan dan sedimen. Pada setiap petak lahan ditanami tanaman penguat guna meningkatkan kestabilan lereng dan perlindungan lahan. Program ini menunjukkan potensi besar dalam meningkatkan kesadaran dan penerapan konservasi tanah oleh petani setempat

Abstract

Terdapat sekitar 900 titik pertambangan emas skala kecil (PESK) di Indonesia yang memperoleh emas melalui teknik amalgamasi dan sianidasi. Teknik amalgamasi menyebabkan pencemaran merkuri (Hg) di tanah. Penelitian ini merupakan penelitian pendahuluan (preliminary study) yang bertujuan untuk mengisolasi mikroorganisme endofit dan rhizosfer resisten Hg dari rumput pionir yang tumbuh di tanah yang tercemar Hg. Mikroorganisme paling berpotensi akan diaplikasikan pada fitoremediasi merkuri di penelitian selanjutnya. Sampel rumput pionir diambil dari lahan pertanian bekas kawasan pertambangan emas dengan teknik amalgamasi di Desa Bonjeruk, Kecamatan Jonggat, Kabupaten Lombok Tengah, Nusa Tenggara Barat. Total mikroorganisme dihitung menggunakan Colony Forming Unit (CFU) atau Standard Plate Count. Koloni mikroorganisme dikarakterisasi berdasarkan ciri morfologi. Mikroorganisme endofit dan rizosfer yang resisten Hg berhasil diisolasi dari rumput pionir (Cynodon dactylon dan Eleusine indica) di lokasi penelitian. Koloni mikroorganisme rizosfer sangat beragam secara morfologi dibandingkan dengan mikroorganisme endofit berdasarkan jumlah mikroorganisme terisolasi, berturut-turut 20 isolat dan 17 isolat. Kepadatan mikroorganisme rizosfer lebih tinggi (96%) dibandingkan mikroorganisme endofit (4%). Kepadatan bakteri dan jamur rizosfer masing-masing adalah 47x103 dan 2x103 CFU g-1 sedangkan kepadatan bakteri endofit dan jamur masing-masing hanya 2x103 dan 1x103 CFU g-1.

Abstract

The continuous use of chemical fertilizers and pesticides in soil can result in the presence of cadmium (Cd) residues that may interfere with plant growth and pose a risk of uptake by plants. The issue of soil contamination by Cd can be addressed through soil bioremediation, which involves the use of Cd-resistant bacteria and compost. The objective of this study was to analyze the impact of Cd-resistant bacteria and compost application on the growth and Cd uptake of water spinach. The research design was a completely randomized design with seven treatments: (1) control, (2) 5 mL Cd-resistant bacteria consortium, (3) 10 mL Cd-resistant bacteria consortium, (4) 10 tons/ha compost, (5) 20 tons/ha compost, (6) 5 mL Cd-resistant bacteria consortium +10 tons/ha compost, and (7) 10 mL Cd-resistant bacteria consortium +20 tons/ha compost. The results demonstrated that the application of Cd-resistant bacteria and compost did not notably impact the growth of water spinach. However, it did significantly influence the reduction of Cd uptake in water spinach. The application of the Cd-resistant bacterial consortium and compost was effective in reducing the Cd uptake of the water spinach plants in all treatments. The combination of 10 mL of bacterial isolate and 20 tons/ha of compost demonstrated the greatest reduction in Cd uptake by water spinach, reaching 73%. Keywords: Bioremediation, Cadmium-resistan bacteria, Compost, Environmental monitoring, Soil contamination.

Abstract

Lead (Pb) is a toxic heavy metal for humans. Agrochemical applications contribute to Pb contamination and accumulation in plants which is harmful to humans. This study aims to investigate the habits of horticultural farmers in applying inorganic fertilizers and pesticides intensively on Pb concentration in the soil and cultivated plants, and its effect on plant growth. The measured parameters consisted of soil and plant Pb content, soil pH, organic C, total N, available P, and exchangeable K. This study used a randomized block design consisting of 4 treatments (Control (KT); (PR); (TN); and (TP)). The results showed that horticultural farmers' dosage of inorganic fertilizers exceeded Indonesia Ministry of Agriculture recommendation. The application of inorganic fertilizers and pesticides by farmers (business as usual) increased Pb content in plants up to 31.46 mg/kg. Besides the application of inorganic fertilizers increases fertilizer residues in the soil by up to 65%, which increases environmental pollution even though the application of inorganic fertilizers increases plant growth and production (shoot length,  the number of leaves, and plant dry weight). Thus, wisely applying agrochemicals is required in order to support plant growth and production without further environmental problems.

Abstract

Soil quality is the ability of the soil to perform its function, such as providing nourishment to the plants. However, intensive paddy farming, such as Hazton’s paddy farming method, is suspected to deteriorate soil quality status and degrade land sustainability. This study aimed to analyze soil quality under Hazton’s paddy farming. This study was conducted on paddy fields in Banyumas Regency using a randomized block design with treatment consisting of 1) conventional method as a control, 2) Hazton’s method + organic fertilizer, 3) Hazton’s method + organic fertilizer + decomposer, and 4) Hazton’s method + organic fertilizer + decomposer + leaf fertilizer. Soil quality was determined according to a minimum data set (MDS) that consisted of organic C, pH, total N, available phosphorus (P) and potassium (K), base saturation (BS), cation exchange capacity (CEC), bacterial density, soil respiration, and C/N ratio. The MDS was scored and calculated using the soil quality index formula and then classified from very low to very high (<0.19-1). This study highlighted that the soil quality in paddy farm using Hazton’s method in Banyumas Regency ranged from low (0.444) to very low (0.308). The application of organic fertilizer is not sufficient enough to refill the nutrient pool equal to harvested plant biomass. This leads to soil quality deterioration and affects land sustainability. Therefore, yield and biomass production should be included as soil quality indicators in future studies. Additionally, further soil degradation can be avoided by continuously assessing soil quality and the necessary conservation measures for preventing and minimizing further land degradation can be applied.

Abstract

Precise and detailed land mapping is essential for sustainable land management, environmental conservation, and regional planning, especially in complex and diverse landscapes. This study aims to present an innovative framework for the development of Land Mapping Units (LMUs) at a detailed scale (1:20,000), through the integration of Random Forest (RF) analysis and high-resolution remote sensing data. This study was conducted in the South Malang Plateau, Indonesia (the area characterized by karst, tectonic, volcanic, and alluvial landforms) from June to December 2024. As part of the methodology, the study utilized a combination of geospatial data, including geological maps, DEM-derived topographical indices, and remote sensing indices (Normalized Difference Soil Index/NDSI, Soil Adjusted Vegetation Index/SAVI, Normalized Difference Water Index/NDWI, Modified Soil Adjusted Vegetation Index/MSAVI). A total of 10,903 field observation points were analyzed, with 70% used for model training and 30% for validation. The results show that RF-based LMUs achieved R2 of 0.93 and Root Mean Square Error (RMSE) of 0.645, which is reliable to use. The LMUs provide a comprehensive understanding of landform-specific characteristics, including soil fertility linked to parent material, erosion sensitivity, and slope variability. These insights support applications in precision agriculture, disaster mitigation, and environmental planning. Moreover, the result can guide informed decision-making to prioritize sustainable land management that effectively prevents land degradation in the South Malang Plateau region, as stated in the Sustainable Development Goals (SDGs). The study demonstrates the potential of combining machine learning and remote sensing to refine spatial analysis and address the limitations of manual mapping methods. The proposed framework is scalable and adaptable to other diverse landscapes, making it a valuable tool for advancing sustainable land management in a rapidly changing world.
