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

This study aims to formulate a development strategy for the Climate Village of Eka Jaya Village and Tanjung Sari Village in Jambi City using SWOT analysis. The instrument used to compile the company's strategic elements is the SWOT matrix. This matrix effectively describes how external opportunities and threats faced by the company can be aligned with its strengths and limitations. This matrix can provide four sets of potential strategy possibilities. The research findings indicate that the development approach for the Climate Village in Eka Jaya Village and Tanjung Sari Village shows significant potential. The main strengths of Eka Jaya are community dedication, local government involvement, and collaboration with the commercial sector. The main constraints are financial constraints and regulatory restrictions. The main opportunities are external funding and environmental laws, while the main risks are environmental degradation and climate change. In Tanjung Sari, the main strengths are ongoing commitment and stakeholder collaboration, while the main problems are financial constraints and political fluctuations. The main opportunities are external funding and program credibility, while the main risks are environmental degradation and climate change. The strategy includes enhancing strengths and opportunities while addressing weaknesses and threats.
