Abstract

This study seeks to evaluate the effectiveness of coconut shell biochar (CB)  and/or Leucaena compost (LC) as ameliorants in improving soil chemical and physical properties, as well as enhancing tomato yields. The goal is to identify the most effective combination of ameliorant formulations that can improve land quality and increase yield of tomato. The study was carried out over a 10-month period, spanning from March 2024 to December 2024. The research method used a Group Random Design, the treatments studied were: A0: no ameliorant + inorganic fertilizer as recommended;   A1 :  CB 15 Mg ha-1;   A2 :  LC 15 Mg ha-1;   A3 : LC 5 Mg ha-1 + CB  10 Mg ha-1;   A4 : LC 10 Mg ha-1 + CB 5 Mg ha-1. All treatments were repeated 5 times.  The data obtained from this study were subjected to statistical analysis and further evaluated using the Duncan’s New Multiple Range Test (DNMRT). The findings reveal that applying coconut shell biochar and Leucaena compost, whether individually or in combination, markedly enhances the physical properties of the soil. These improvements include reduced bulk density (BD), increased soil organic matter SOM), total porosity (TP), and hydraulic conductivity (HC), as well as better pore distribution and water retention. Furthermore, these treatments resulted in an increase in both the tomato weight per plant and the fresh tomato weight per plot. The most effective combination for maximizing tomato yield was determined to be 10 Mg ha-1 of LC combined with 5 Mg ha-1 of CB.

Abstract

ABSTRACT Land conversion due to human activities, such as clearing forest land for agricultural use, has led to a decline in land quality. This decline is characterized by a deterioration in the physical properties of the soil, reduced water absorption capacity, and increased surface runoff. Land use changes in highland areas generally involve slopes with gradients exceeding 15%. The village of Mukai Pintu is situated in the Siulak Mukai sub-district of Kerinci District. The area has undergone land use changes, where land on steeper slopes has a high potential for erosion and landslides. The objective of this study is to investigate changes in several physical properties of soil resulting from land conversion from forest to agricultural land on slopes with gradients of 25-40% and greater than 40% in Mukai Pintu Village. This study employed a survey method with a purposive sampling approach. The study focused on three land uses: forest, mixed gardens, and fields, as well as two slope classes: 25-40% and greater than 40%. The results of this study indicate that the conversion of forest land into agricultural land (mixed gardens and fields) causes changes in several physical properties of the soil, particularly on slopes with gradients of 25-40% and 40%, including a decrease in soil porosity, soil organic matter, percentage of formed aggregates, aggregate stability, soil permeability, and an increase in soil bulk density. Significant changes in soil physical properties occurred in fallow fields   Keywords: forest conversion, Kerinci, land use, soil physical properties   ABSTRAK Konversi lahan akibat aktivitas manusia dalam membuka lahan hutan menjadi lahan pertanian menyebabkan penurunan kualitas lahan.

Abstract

Ultisol is one type of soil available for the development of oil palm plantations in Indonesia. Oil palm development is faced with negative perceptions due to the degradation of soil and regional hydrological functions. The purpose of this research was to evaluate the impact of the application of biopores filled with various types of oil palm waste on the hydrological function of Ultisols with oil palm plantations. This research used an experimental method designed by creating eight experimental plots consisting of seven plots with biopores filled with various types of oil palm waste and one plot without biopores. The research data included organic carbon content, bulk density, porosity, permeability, infiltration, and water retention of soil. Data were obtained through analysis of soil samples in the laboratory and field measurements. Data were analyzed descriptively and by regression analysis with a confidence level of 95% (? = 0.05). The research results showed that the application of biopores with various oil palm wastes was able to improve soil characteristics and hydrological functions of Ultisols in oil palm plantations. The application of biopores with a combination of Mucuna bracteata, empty oil palm fruit bunches, oil palm pruning leaves, and oil palm shell biochar showed the best effect on improving soil characteristics and hydrological functions. Improvement of soil characteristics was correlated with improvement of hydrological function in Ultisols. Therefore, biopores filled with oil palm waste can be recommended as an integrative soil and water conservation technology for controlling the hydrological functions of Ultisols in oil palm plantations.

Abstract

Low infiltration is one of the limiting factors on suboptimal land for agriculture. The infiltration is closely related to the soil's available water for plants. Low infiltration impacts soybean productivity. The contour planting system is a soil and water conservation technology that can be applied to increase infiltration. This research aimed to examine the impact of modifying the contour planting system on the infiltration characteristics of suboptimal land and soybean yields. The research used a quantitative approach with experimental methods (split-plot design) and three replications. The main plot treatment was the position of the land on the slope (the upper, middle, and lower). The subplot treatment was the contour planting system (standard contour planting system, 30o, 45o, and 60o from the contour line). Data were analyzed using analysis of variance and Duncan’s Multiple Range Test. The results showed that the modification of contour planting systems had no significant effect compared to the standard contour planting system in improving organic carbon content, bulk density, infiltration characteristics, and soybean plant height. The standard contour system resulted in higher soybean yields than the modification of the contour planting system. The position of the soil had a significant influence on soil properties, infiltration characteristics, plant height, and yields of soybeans. The soil characteristics, infiltration characteristics, and soybean yields resulting from standard and modification of contour planting systems showed suboptimal improvements. Therefore, further studies are needed to optimize the application of modification of contour planting systems to support the implementation of conservation agriculture systems.

Abstract

This study analyzes the local wisdom of the Skouw community in Muara Tami District, Jayapura City, as a contextual science learning resource to stimulate elementary school students’ critical thinking skills through a deep learning approach. Motivated by the scarcity of culturally relevant learning resources in elementary science education—particularly in communities with rich indigenous ecological knowledge—this investigation employed a qualitative exploratory case study design complemented by a development-oriented stage. Data were collected through observations, semi-structured interviews, and document analysis involving school principals, science teachers, and selected elementary school students, as well as school documents and contextual community observations. Analysis followed a systematic procedure comprising data reduction, coding, data display, thematic interpretation, and conclusion verification, with trustworthiness ensured through source triangulation, method triangulation, and member checking. The findings indicate that Skouw local wisdom—encompassing environmental knowledge, traditional agricultural practices, simple technology, customary resource management, and cultural values—can be meaningfully connected with elementary science concepts such as ecosystems, biodiversity, conservation, adaptation, energy, simple machines, and human–environment interaction. Implementation of local wisdom-based science learning encouraged students to relate scientific concepts to real-life cultural and ecological experiences, participate more actively, and develop reflective and analytical thinking. However, challenges related to limited contextual learning resources, teachers’ competence, school–community collaboration, and learning facilities were also identified. The study implies that culturally grounded science learning can provide an alternative pedagogical framework for contextual, meaningful, and identity-based science education, while supporting teachers in designing activities that stimulate critical thinking through local cultural resources.
