Abstract

Vertisol has a clay texture, high micropores, and high water and nutrient absorption ability. The high water content of Vertisol causes the air to decrease, thus inhibiting root development. Stretching of the Vertisol structure is expected to increase soil porosity and reduce ion and water absorption. This study examines interactions between organic matter and percent sand on soil porosity and nutrient availability. The study was arranged according to a factorial Completely Randomized Design (CRD), repeated three times. The first factor was seven kinds of organic matter (control, cow dung + banana peel compost, cow dung + leaf litter compost + compost water hyacinth + cow dung, humin, humic acid, and biochar. The application doses are respectively for each treatment: humic acid and humin 20 kg ha-1, biochar 1 Mg ha-1, compost+manure fertilizer 15 Mg ha-1. Changes in soil chemical characteristics were evaluated against pH, C-org, and Available-P, while changes in soil physical characteristics were evaluated against bulk density, particle density, and soil porosity. The results showed that the combination of organic matter and percent sand could improve the physical and chemical characteristics of the soil. Bulk density (BD), particle density (PD), and soil porosity increased with the addition of sand. The organic matter significantly correlated with improving soil properties was humic acid, humin, biochar, compost, and manure, with the best percentage of sand at 20%.

Abstract

Soil contamination by heavy metals poses a significant threat to sustainable agriculture, especially in areas adjacent to industrial zones. This study demonstrates that while the initial application of the biosilica-humic acid (BSi-HA) soil amendment did not result in statistically significant changes in soil chemical properties within the first 7 days of incubation, prolonged incubation for 60 days revealed meaningful effects, particularly in reducing heavy metal availability in soil. Significant decreases in iron (Fe) and lead (Pb) concentrations were observed over time, with Fe reductions ranging from 45–67% and Pb reductions between 8–40%. These results are attributed to the synergistic effect of functional groups in BSi-HA—especially the carboxyl (–COOH) and hydroxyl (–OH) groups in humic acid—which exhibit high metal-binding affinity under acidic conditions (pH ~5). Although soil fertility parameters such as C-organic content and cation exchange capacity (CEC) showed a declining trend due to microbial activity during incubation, the ability of BSi-HA to immobilize heavy metals without exceeding safe thresholds highlights its potential as a sustainable soil amendment. Moreover, previous findings indicating reductions of up to 90% for Pb and 76% for Cd in plant tissues further support the efficacy of BSi-HA in mitigating heavy metal contamination in agricultural soils near industrial zones. Further long-term studies are recommended to evaluate BSi-HA's remediation capacity, persistence, and impact on crop yield and food safety. Combining biosilica and humic acid offers a promising, eco-friendly approach for managing heavy metal contamination in soils.

Abstract

Salah satu permasalahan lahan pertanian adalah terjadinya salinisasi tanah yang biasa terjadi pada lahan yang berdekatan dengan garis pantai. Kabupaten Lamongan dan Tuban merupakan dua daerah yang berdampingan dan berbatasan dengan garis pantai utara. Kedua daerah merupakan dua daerah yang berkontribusi dalam produksi padi tertinggi di Jawa Timur. Keduanya memiliki bagian pesisir yang dimanfaatkan untuk kegiatan budidaya sehingga memerlukan perhatian. Penelitian ini bertujuan untuk mengidentifikasi salinitas tanah dan dampaknya terhadap hasil produksi padi di hilir Kabupaten Lamongan dan Tuban. Penelitian ini menggunakan metode deskriptif eksploratif dan kegiatan pengambilan sampel tanah dilakukan dengan menggunakan metode cluster sampling berdasarkan pada jarak titik pengambilan sampel dengan garis pantai. Titik pertama ditetapkan pada jarak sekitar 2 km dari garis pantai, lalu berjarak 1 km ke titik berikutnya. Lahan T1 memiliki nilai EC tertinggi yaitu 0,65 dS.m-1 dan kurang dari 2 dS.m-1 sehingga dikategorikan sebagai lahan non salin dan pengaruhnya terhadap tanaman dapat diabaikan. Penggunaan pupuk anorganik (Urea dan Phonska) yang melebihi dosis tidak meningkatkan hasil produksi, melainkan pengaruh positif dan signifikan berasal dari masukan pupuk kandang yang diberikan di lahan. Penambahan bahan organik berupa pupuk kandang ke lahan dapat ditingkatkan untuk meningkatkan kestabilan sifat fisik dan kimia tanah serta hasil produksi.

Abstract

Land is an important part of the watershed because it is where the hydrological process occurs. There are several problems that can lead to land damage, especially in the downstream area of the watershed, precisely in the Manten Sub-watershed because it has the potential to become critical land. Therefore, this research was conducted with the aim to overcome the existing problems, it is necessary to identify the standard of land degradation in the Manten Sub-Watershed area in accordance with PP No. 150 of 2002. Manten sub-watershed covers 4 sub-districts namely Wajak, Poncokusumo, Tajinan, and Bululawang. Land use in Manten sub-watershed is divided into 3, namely rice fields, kailyards and fields. Based on the results of the analysis of all land use in Manten Sub Watershed, all parameters that have been observed do not exceed the critical threshold criteria except for the redox parameter has a very low value of <200mV. However, this condition can still be improved with proper management such as improving soil aeration using the addition of organic materials so as to increase oxygen levels in the soil and increase redox values.

Abstract

Land damage generally occurs due to erosion by the flow of rainwater on the soil surface. Erosion is closely related to the intensity of rainfall in an area and the slope of the land (slope). Soil erosion is an environmental problem which, if left unchecked in the long term, can reduce soil fertility. The Erosion Hazard Index (EHI) is used as a solution in controlling erosion at certain locations. The research was conducted in the Kali Gunting Sub-watershed in Wonosalam District, Jombang, East Java, in January 2021 to April 2023. The research locations covered several villages, namely: Galengdowo, Jarak, Wonomerto, Sambirejo, Wonosalam, Carangwulung, Panglungan, Wonokerto and Sumberrejo. Meanwhile, for soil sample analysis activities carried out at the Land Resources Laboratory I and II of the Faculty of Agriculture, East Java "Veteran" National Development University. Determination of the Erosion Hazard Index (EHI) is conductedusing the RUSLE method. The results showed that the villages of Carawangwulung, Jarak, Wonokerto, Sumberejo, Wonosalam, Wonomerto, Galengdowo, Sambirejo and Panglungan had EHI in the very low category. Efforts that can be made to maintain the rate of erosion are to maintain annual plants, add organic mulch from the remaining twigs and leaves, change traditional terraces to bench terraces and apply the Groundwater Conservation Area system. Furthermore, land with traditional terrace conservation in Sambirejo and Wonokerto sub-districts can be replaced by making bench terraces.

Abstract

The state asset land managed by UPN "Veteran" East Java is located in the Wonosalam District based on land certificate data issued by the Jombang BPN covering 13.5 hectares. Currently more than 50% of the land has not been used optimally to support learning, research and community service. The problems that arise in utilizing land assets to support learning, research and community service are 1) the legal boundaries of land ownership are not yet clear, 2) there is no land use master plan to support the learning process, 3) there is no potential data that can be used. prepare use and development plans. Against the background of the problems above, this research aims to map the potential of state land assets by "spatial interpolation, scoring and weight overlay" of land characteristics. Interpolation is a way of calculating the area of several representative measurement points, while scoring and "Weight Overlay" is a facility provided by ArcMap GIS which combines input spatial data with weighting (weight factor) and scoring. Land unit maps are obtained from overlaying relief, geology, slope and land use maps. Interpolation, Scoring and Weight Overlay of the nine land characteristics yielded a potential land asset for buildings, good category 16.61% (44,130.38 m2); moderate 25.66% (67,382.75 m2) and bad 7.523% (19,784.88 m2). Playing field potential, good category 54.73% (71,865.05 m2) and medium 45.27% (59,432.62 m2). Potential for road infrastructure development in the good category 32.38% (42513.74 m2); Moderate 42.68% (56035.24 m2) and Bad 24.94% (32748.69 m2), and all of these potentials are in Slightly Flat topography (Slope, 0-3%) to hilly (Slope, 15-25%).

Abstract

Soil erodibility is an important factor in determining soil loss. The objective of this study was to evaluate the soil erodibility value based on the Wischmeier-Smith Method. The study was carried out in Jatiarjo Village, Prigen District, Pasuruan Regency, at four land use units (LUU), including Mounts (MO), Mixed Garden (MI), Monoculture Garden (MG), and Shrubs (SR). Wischmeier-Smith algorithm was used to determine the erodibility values and classification. Results showed that shrub was identified as the land use with the highest potential for erosion and erodibility value. The correlation between clay fraction and erodibility has a negative value wit r = -0.76, while other fractions had r value < 0.5. This implied that the clay fraction and soil erodibility have an inverse relationship, where each increase in the clay fraction value will be followed by a decrease in the erodibility value. One way to reduce soil erodibility is to increase plant diversity on the land. Apart from adding organic matter, a variety of plants also have roots that are able to bind soil aggregates and help absorb water into the soil, thereby reducing water flow on the surface. If conservation is not taken seriously, it can undoubtedly result in.
