Abstract

Ultisol merupakan tanah marginal dengan keterbatasan sifat fisik, seperti struktur tanah padat, permeabilitas dan infiltrasi rendah, aerasi buruk, serta kandungan bahan organik rendah yang dapat menurunkan produktivitas tanaman. Penelitian ini bertujuan mengevaluasi pengaruh pengolahan tanah konservasi dan mulsa jerami padi terhadap sifat fisik Ultisol serta hasil jagung manis (Zea mays saccharata Sturt). Penelitian dilaksanakan di Kenali Asam Bawah, Kecamatan Kota Baru, Kota Jambi, menggunakan Rancangan Acak Kelompok (RAK) dengan lima perlakuan dan lima ulangan. Perlakuan meliputi pengolahan tanah konvensional (P0), olah tanah minimum + 30% jerami padi (P1), olah tanah minimum + 60% jerami padi (P2), tanpa olah tanah + 30% jerami padi (P3), dan tanpa olah tanah + 60% jerami padi (P4). Parameter yang diamati meliputi bahan organik tanah, berat volume, total ruang pori, kadar air tanah, permeabilitas, kemantapan agregat, dan hasil jagung manis. Hasil penelitian menunjukkan bahwa perlakuan olah tanah minimum dengan 60% jerami padi (P2) memberikan pengaruh terbaik terhadap perbaikan sifat fisik tanah melalui peningkatan bahan organik, total ruang pori, kadar air tanah, permeabilitas, dan kemantapan agregat, serta penurunan berat volume tanah. Perlakuan ini juga menghasilkan produksi jagung manis tertinggi sebesar 15,72 ton ha?¹. Dengan demikian, kombinasi olah tanah minimum dan mulsa jerami padi berpotensi meningkatkan kualitas Ultisol dan produktivitas jagung manis secara berkelanjutan.

Abstract

Flash floods are a hydrometeorological disaster that frequently occurs in mountainous watersheds, particularly in areas with land use that is not in accordance with its natural geomorphological conditions. This study aims to analyze the geomorphological characteristics of the Anai Valley, determine the level of flash flood vulnerability based on the integration of biophysical parameters, and assess the contribution of geomorphological mismatches to increasing flash flood vulnerability. This study uses a Geographic Information System (GIS) approach with a weighted overlay method through the integration of slope gradient, soil type, land use, river buffer, and rainfall parameters. The results show that the Anai Valley area is dominated by steep to very steep slopes, volcanic and alluvial soil types, and land use activities that develop along the Batang Anai River. High to very high flash flood vulnerability zones are concentrated in the valley plains and river corridors. Land use mismatches on steep slopes and river boundaries contribute significantly to increased surface runoff and environmental degradation.

Abstract

Spodosols are widely distributed across Indonesia, covering approximately 2.16 million hectares, presenting significant potential for utilization as industrial forest plantation land, heavily reliant on its physical properties. The selection of the type of HTI plants to be cultivated depends on their adaptability. Eucalyptus is one plant known for its good adaptability to less fertile soil. This research was conducted on the land of PT. Wirakarya Sakti for 3 months, from February to April 2023, located in District 1, Betara District, Tanjung Jabung Barat Regency, Jambi Province. The aim of the research is to investigate the impact of land use planted with Eucalyptus compared to conservation forest on the physical properties of the soil. The research utilized a field survey method covering an area of approximately 326.4 hectares and the determination of points and sample collection using the stratified random sampling method. Samples were taken at locations including the conservation forest and land planted with Eucalyptus aged 1, 2, and 3 years, with 6 samples taken at depths of 0-30 cm and 30-60 cm, totaling 48 samples. Observed variables included soil texture, organic matter, bulk density, total pore space, moisture content, and permeability. The research results indicate that the physical properties of Spodosol soil include high soil volume weight due to the presence of an albic horizon in the upper layer and a spodic horizon in the lower layer, as well as high organic carbon content in the spodic horizon

Abstract

Smallholder oil palm plantations generally do not apply organic fertilizer management systems or soil conservation techniques, whereas large private plantations (PT. MSP) apply organic fertilizers in the form of empty fruit bunches and implement soil conservation practices. Differences in land management between smallholder plantations and large-scale oil palm companies influence the physical properties of the soil. This study was conducted to compare the quality of soil physical properties in oil palm plantation areas of smallholder plantations and large private plantations (PT. MSP) in Bungo Regency, Jambi Province. The study employed a Systematic Grid Survey method, in which undisturbed and disturbed soil samples were collected at a depth of 0–30 cm within several Homogeneous Land Units (HLUs). The soil samples were subsequently analyzed for soil texture, bulk density, total pore space, moisture content, aggregate stability, and organic matter content. The resulting data were used to calculate the Soil Physical Quality Index (SPQI) as an indicator of soil physical quality. The results indicated that soil quality in the PT. Mega Sawindo Perkasa plantation was classified as ‘moderate,’ with an average SPQI value ranging from 0.59 to 0.69. In contrast, the smallholder plantations were categorized as ‘fairly poor,’ with an average SPQI value ranging from 0.50 to 0.56. To improve soil quality, it is recommended that smallholder plantations apply organic fertilizers and implement terracing practices to reduce erosion and enhance soil structure.
