Abstract

Organic farming has been advocated as a more environmentally sound and ecologically balanced alternative to the dominant agricultural model. This study compared the decomposition of plant biomass in organically and non-organically managed soil properties. The treatments consisted of   non-organic land (A) and organic land (B). Non-organic land used chemical fertilizers as the main fertilizer, and organic fertilizers were not always given. In organic land, all fertilizers given were organic fertilizers, and organic pesticides have been carried out over the last five years. The area of ??each land studied was approximately 1,000 m2 divided into five points diagonally. Observations were made on soil pH, organic C, total N, and P Bray, as well as the amount and weight of soil macrofauna. The decomposition rate of the dried Edamame soybean biomass in the soil was estimated using the litterbag method. A litterbag measuring 30 x 20 cm with a pore size of 2-3 mm was used for this study. Seventy grams of plant biomass were put into the litterbag and buried in the soil to a depth of 10-20 cm. Analysis of C and N contents in plant biomass was carried out before and after incubation in the soil. The results showed that soil chemical properties are better, and soil macrofauna is more abundant in organic than non-organic land. Soil fertility in organic land was characterized by a larger decomposition rate constant (k) and a faster decrease in C/N ratios. The decomposition rate constant (k) in organic soil was 0.171, and that in non-organic soil was 0.105.

Abstract

The Karimunjawa National Park area has various coastal resources and ecosystems, such as mangrove forests, seagrass, and coral reefs, which provide a habitat for several vital organisms. The presence of natural and human factors in coastal areas causes environmental degradation. Changes in environmental conditions, increasing population, and land requirements in Karimunjawa National Park can have negative impacts if not appropriately managed. Therefore, coastal management strategies are needed to maintain sustainability and prevent the extinction of coastal resources. The research locations are Karimunjawa Island and Kemujan Island. This research aimed to develop a coastal management strategy based on changes in the shoreline of Karimunjawa Island and Kemujan Island. The SWOT (Strengths, Weaknesses, Opportunities, Threats) analysis model was used to identify coastal management strategies through the most effective priority scale. The research results showed that in 2008-2023, the average erosion on Karimunjawa Island was -11.41 m or -0.75 m/year, and accretion was 13.30 m or 0.87 m/year, while the average erosion on the island rainfall was -13.74 m or -0.90 m/year and accretion is 13.30 m or 1.07 m/year. Management strategies that can be implemented are (1) forming a board or committee; (2) conducting outreach and education activities; (3) identifying critical areas; (4) developing protection and utilization programs; (5) conducting research; (6) monitoring; (7) formulating policies.

Abstract

Degraded alluvial soil that is commonly used for growing ginger (Zingiber officinale) has many issues, such as deficiency in nutrients. To increase the yield of ginger, proper fertilizers along with soil improvement techniques must be employed. In this case, the study analyzed the combined effects of rice husk biochar and Mahkota NPK fertilizer on the yield and growth of ginger in alluvial soil. The study was performed using a completely randomized design arranged with two treatment factors. The first factor was the application of rice husk biochar consisting of three different levels: s1 (5 t/ha), s2 (10 t/ha), and s3 (15 t/ha). The second factor was the application of Mahkota NPK fertilizer consisting of three levels: m1 (50 kg/ha), m2 (150 kg/ha), and m3 (250 kg/ha). The results of this study showed that the treatment combination of rice husk biochar and Mahkota NPK fertilizer was highly significant in improving bulk density, total porosity, pH, organic C, total nitrogen, available phosphorus, and potassium of the Alluvial soil. The interaction also greatly affected plant growth in terms of height, tiller formation, and weight of fresh rhizomes. However, the number of leaves remained uninfluenced. The highest yield was obtained with s2m3 treatment (10 t/ha rice husk biochar and 250 kg/ha NPK fertilizer). From this result, it can be suggested that the application of rice husk biochar in combination with Mahkota NPK fertilizer has the potential to remedy degraded alluvial soils and improve the growth and yield of ginger in the soils.

Abstract

The management of Artisanal and Small-scale Gold Mining (ASGM) in Sekotong Sub-district, West Lombok Regency, encounters considerable challenges due to environmental and social repercussions. These situations indeed need to be restored by conducting the mining activities sustainably. This study examined stakeholders' interactions and influences in the context of sustainable ASGM management by employing the MACTOR method. MACTOR is a method used to identify key actors, relationships between key actors, and their strategic objectives. Research data were obtained from structured interviews and field data, which were then processed to identify each actor's level of influence and dependence in the management of ASGM Sekotong. The results of the analysis showed DESDM, DLH, DIKOP, and DIKES as actors with high influence and low dependence. Meanwhile, miners and cooperative administrators were actors who had high influence and high dependence on the management of ASGM Sekotong. In addition, the level of convergence between DESDM and UNDP showed a commitment to sustainable practices of ASGM Sekotong, while the divergence of DESDM and miners highlighted the challenges in the management of ASGM Sekotong in aligning the goals of economic development and preserving the environment. This study emphasized the importance of strengthening the role of actors with low influence and reducing their dependence on dominant actors. Strong alliances among actors are essential to support the sustainable management of Sekotong ASGM. These findings provide strategic insights to formulate more inclusive and sustainable Sekotong ASGM policies and practices.

Abstract

Soil Quality Index (SQI) assessment is a crucial parameter for evaluating the effectiveness of land reclamation objectives. This research aimed to analyze trends in soil quality changes across various stages of post-coal mining reclamation. This research was conducted in June 2024 at sites with varying soil ages at PT Inti Bara Perdana and in natural forest areas. This research employed descriptive-exploratory methods and involved open-field surveys. Sampling was conducted using purposive sampling at locations representative of the conditions at each site. Principal Component Analysis (PCA) was utilized to identify key indicators and determine the SQI. The results demonstrated that post-mining land reclamation significantly improved the physical, chemical, and biological quality of the soil. While the reclaimed soil quality has not yet fully reached the level of natural forest soil, the reclamation process exhibits strong potential for ecosystem recovery. SQI analysis revealed an increasing trend in soil quality as the reclamation age advanced. Linear variable analysis indicated a positive correlation between reclamation age and SQI development. Reclaimed areas aged 7 and 11 years exhibited SQI values exceeding 0.5, signifying successful reclamation and ecological sustainability.

Abstract

Excessive pesticide use and intensive shallot farming to satisfy high market demand can degrade soil quality and harm environmental sustainability. Sustainable agricultural practices, such as biochar and compost are alternatives to ensure long-term soil productivity and fertility. This study aimed to investigate the ability of biochar and compost made from bagasse waste to improve shallot growth, yield, nutrient absorption, and soil quality. The research used a factorial randomized block design in a greenhouse. The first factor was the application of biochar and compost (K1 = compost, K2 = biochar, K3 = biochar-compost (1:4/w:w) and K4 = biochar-compost (1:2/w:w), and the second factor was the dose of NPK fertilizer (0%, 50%, and 100% of the recommended dose). The planting medium used was an Inceptisol from shallot fields in Sukaharjo, Central Java. The variables measured included plant growth, yield components, soil chemical properties, and levels of N, P, and K in plants. The results showed that the combination of compost with 100% NPK fertilizer gave better results in plant growth, fresh and dry weight of plants and tubers, increased organic C, total N, and CEC of the soil, and increased the absorption of N, P, and K by plants.

Abstract

Land use changes and rainfall can trigger inundation. This study aimed to observe the dynamics of spatial patterns of temporal flood vulnerability due to rainfall and land use changes using the Maximum Entropy (MaxEnt) Model. Flood vulnerability was assessed using 12 environmental variables, including elevation, slope gradient, slope direction, slope curvature, Topographic Wetness Index (TWI), flow density, distance from rivers, distance from roads, soil texture, soil aggregates, rainfall, and land use. Rainfall and land use were dynamic variables analyzed in 2013-2023. Past flood occurrence points were obtained using the participatory mapping method. Temporal flood vulnerability mapping in 2013, 2018, and 2023 showed the influence of elevation, Topographic Wetness Index (TWI), and distance from rivers, which were very dominant. Typically, the flood vulnerability pattern formed showed a percentage of moderate (13%), high (17%), and very high (5%) class areas consistently clustered in the southern region. An interesting finding is that rainfall changes have a more significant influence (7.2%), causing the dynamics of high and very high-class vulnerability patterns, compared to the influence of land use changes (0.4%). MaxEnt's flood vulnerability prediction accuracy is classified as very good, as evidenced by its AUC values of 0.835 in 2013, 0.819 in 2018, and 0.824 in 2023. Finally, the findings showed that the accuracy of the MaxEnt Model is classified as very good, so it can be extrapolated globally with similar regional typologies.

Abstract

The presence of greenery in urban residential and office areas can improve the comfort of residents who live in these environments. In an urban setting, vegetation serves an ecological purpose by absorbing carbon dioxide, supplying oxygen, lowering the temperature to produce a tolerable microclimate, acting as a water catchment area, and reducing noise. Urbanization and anthropogenic activity-driven growth of urban and            sub-urban regions put stress on the local vegetation and have the potential to lower environmental comfort. To promote the creation of a sustainable urban environment, a thorough analysis of the urban environment is required. Applications for remote sensing in all spectral, geographic, and temporal dimensions have increasingly adopted the usage of deep learning methods with artificial neural networks. This study attempted to predict the application of remote sensing data for analyzing environmental comfort in metropolitan areas based on multitemporal Landsat-8 data. The study area is Greater Jakarta. The approach was based on supervised classification with neural network techniques and land parameters like surface temperature, brightness index, greenness index, and wetness index. According to the study's findings, the proposed method could accurately predict that very uncomfortable classes predominated in Jakarta, Bogor, Depok, Tangerang, Bekasi, and surrounding areas by more than 92%. In addition to being densely populated with communities, urban environments are uncomfortable due to a lack of vegetation cover, which increases surface temperatures. In the future, this research can provide input for similar research, especially in the use of deep learning Artificial Neural Network methods for environmental analysis.

Abstract

Soil fertility maps are vital tools in agriculture and land management, offering essential information for decision-makers. The availability of soil nutrients significantly impacts crop production. This study aimed to assess soil nutrient content and develop a soil fertility map for mixed farmland in the Banggai Islands region of Central Sulawesi, Indonesia. The research involved soil sampling at a depth of 0-20 cm from 60 random points, followed by laboratory analysis and geostatistical interpolation using the Kriging Semivariogram (Spherical) method in ArcGIS to create the soil fertility status map. Validation was conducted using absolute mean error (AME) and absolute error of variation (AVE). Results indicated that soil pH in the area ranged from slightly acidic to neutral, while organic C, nitrogen, and cation exchange capacity were evenly distributed but classified as low to medium fertility. Potassium levels were consistently low across the study area. Additionally, available phosphorus varied from low to very high, and base saturation was predominantly high to very high. By overlaying the nutrient distribution maps, three soil fertility categories, very low, low, and medium, were identified. These findings offer valuable insights into nutrient management and sustainable agricultural practices in the Banggai Islands, Central Sulawesi.

Abstract

With its abundant groundwater potential, East Java faces a growing risk of contamination due to rapid industrial growth. This study assessed groundwater quality in four regional groundwater basins (GWB) using the Water Quality Index (WQI), water quality standard comparison, Piper diagram, and hydrogeochemical ion analysis. The WQI analysis revealed that 59% of the samples were classified as excellent and good for consumption, predominantly found in volcanic, river alluvial, and limestone hill areas. In comparison, 11% were unsuitable for consumption due to contamination, particularly near coastal, industrial, and agricultural zones. The Piper diagram showed that most groundwater samples were unpolluted, reflecting the natural interaction between groundwater and surrounding lithology. However, ion standard comparison identified samples exceeding acceptable ion levels, and ion correlation analysis confirmed contamination from industrial, agricultural, anthropogenic, and municipal wastewater activities. These findings highlight the need for targeted groundwater management, particularly in areas vulnerable to contamination.
