Abstract

 The primary role of vegetation is to provide structural support for the surrounding ecosystem, while also contributing to the visual appeal of the road environment. The presence of Green Open Space (GOS) as a venue for sustaining the urban environment is inherently essential, owing to its substantial capacity to enhance both the qualitative and quantitative aspects of urban living. This study aimed to analyze the indigenous vegetation well-suited for developing GOS along road routes within the urban center of Bekasi Regency. The study utilizes a multi-faceted approach, including field surveys, and historical data comparison, to offer a comprehensive analysis of spatial and temporal variations in vegetation diversity. The analysis of vegetation diversity involved the quantification of canopy density, dominance frequency, important/historical value, function in landscape design, and habitat profile analysis of vertical and horizontal structures. These measurements collectively provided an assessment of the state of local vegetation that is being inventoried. The vegetation in Bekasi Regency, within both GOS and urban residential areas, generally meets satisfactory standards in supporting ecological functions. However, in specific residential locations, there remains a lack of diversity in local and rare vegetation. In summary, the study underscores the pressing demand for comprehensive conservation approaches that effectively harmonize development initiatives with the protection of indigenous biodiversity. The results of this study offer a pivotal asset for policymakers and environmental planners in crafting sustainable development strategies for Bekasi Regency.

Abstract

Soil formation in volcanic terrains presents a significant challenge due to the diverse physical and chemical properties imparted by volcanic activity, which are not yet fully understood. This study investigates the unique morphological characteristics of soil profiles within crater topography sequences at the Tangkuban Parahu Volcano, Indonesia. To address this gap, five representative sample profiles (I, II, III, IV, V) were analyzed. The Ratu Crater pathway topography was characterized by steep to very steep slopes. Detailed analysis identified three predominant soil layers, each with distinct features such as color, texture, porosity, and chemical composition, reflecting different stages of soil formation. At the highest elevation near the crater rim, Profile V was composed mainly of volcanic ash, with a loose structure, high porosity, and acidic pH, indicative of recent volcanic deposits. Profile III, at intermediate elevations, consisted of highly weathered soil with sandy loam textures and clear layer demarcations, suggesting prolonged soil development and consolidation. Profile I, at the lowest elevation, featured loamy sand with significant weathering and organic matter incorporation, indicating advanced soil development stages. The findings underscore the impact of volcanic activity on soil morphology, revealing distinct layers that correlate with various ages and developmental stages. Understanding these processes can inform agricultural practices.

Abstract

The Advanced Independent Workforce (AIW) program plays a pivotal role in facilitating the development of micro and small enterprises in Indonesia. Nonetheless, various challenges, including inconsistent mentorship and limited evaluation mechanisms, impede its overall effectiveness. In response to these issues, a Dual Monitoring and Evaluation (DME) system was implemented to enhance the role of AIW mentors. This system comprises one-on-one meetings aimed at delivering personalized guidance, as well as onsite monitoring and evaluation to assess real-time business progress and operational challenges. This initiative was executed across multiple provinces in Indonesia, engaging mentors, mentees, and relevant stakeholders. The findings indicate that the DME system significantly enhances mentor effectiveness, bolsters business sustainability, and improves problem-solving capabilities. The one-on-one meetings afforded structured feedback and capacity-building opportunities for mentors, while onsite evaluations facilitated direct observation and timely interventions for mentees. The integration of direct engagement and field-based evaluation not only strengthened mentorship strategies but also increased mentee confidence and promoted adaptive business practices. This study underscores the importance of a structured mentoring model in workforce development and recommends the expansion of DME coverage, the incorporation of digital tools, and the development of standardized evaluation metrics. This approach presents a scalable model for analogous economic empowerment programs, thereby ensuring sustainable mentorship and the success of enterprises.

Abstract

The primary objective of this study was to determine the current condition, areas, and potential of soil degradation due to biomass production in Bekasi Regency. This study used a survey-based methodology that involved direct field observation and collection of soil samples from specified agricultural and forestry areas based on work maps. The laboratory analysis was conducted on the collected soil samples. The initial phase of soil damage determination involved an evaluation of the current soil condition. Soil condition maps were created utilizing data derived from the determination of key soil parameters based on the standard of so il damage criteria. The result of the analysis indicated that the degree of soil damage in Bekasi Regency due to biomass production varied from slight to moderate. The primary limiting factors were identified as soil permeability (p), redox potential (r), to tal porosity (v), electrical conductivity (e), bulk density (d), and pH level (a). The limiting factors were predominantly influenced by the constraints associated with the physical characteristics of the soil. The phenomenon is commonly associated with the high level of land exploitation, characterized by the use of chemical inputs, resulting in soil compaction. The process of compaction has a substantial impact on soil properties, including permeability, porosity, redox potential, bulk density, and electrical conductivity.
