Abstract

The purposes of this research are (1) to know the influence of genotype and biological fertilizer to the soil biological properties, and (2) to know the influence of genotype and biological fertilizer to the soybean plants productivity at its ultisols. This experiment was conducted at experimental garden of Bengkulu University. It was arranged in factorial split plot design and consisted of two factor. The first factor was soybean cultivars i.e. Pangrango, Ceneng, and DS1 (Malabar and Kipas Putih variety breeding). The second factor was double inoculation of Rhizobium and VAM i.e. Glomus manihotis + Rhizobium of KLR 5.3 strain, Glomus manihotis + Rhizobium of TER 2.2 strain, Gigaspora margarita + Rhizobium of KLR 5.3 strain, Gigaspora margarita + Rhizobium of TER 2.2 strain, fertilizer NPK at recommended dosage without inoculants respectively. The collected data was analyzed statistically and tested by F test at level of 5% and continued with Duncan Multiple Range test for differences among the treatments. The result of the research showed that (1) the soil that had been planted genotype DS1 soybean has the highest level of C-Organic (2,69%) compare with pangrango or ceneng and biological fertilizer produces higher level of respiration than its control. (2) ceneng’s genotype produce the effective amount of nodules, plant dry weight (3,90 g), and seed weight (5,66 g) is higher than if we compare with pangrango and DSI.Keywords : soybean, biofertilizer technology , Ultisols

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

Soybeans (Glycine max (L.) Merrill) are a popular food commodity in Indonesia, but domestic production is still insufficient to meet the demand. To increase production, planting superior varieties on coastal land could be a viable solution. Despite the challenging biological, physical, and chemical conditions of coastal land, nutrients such as phosphorus (P) are crucial for enhancing production. Typically, the phosphorus content in the soil is lower than that of nitrogen (N) and potassium (K), and the ability of soybean plants to absorb phosphorus varies among varieties. This research aims to compare the growth, yield, and phosphorus uptake of four soybean varieties on biocomposted coastal land. The study was conducted using a Randomized Complete Block Design (RCBD) with a single factor consisting of four soybean varieties: Wilis, Anjasmoro, Malika, and Detam 1. The results indicate that the Anjasmoro, Wilis, Detam 1, and Malika varieties exhibit similar responses in phosphorus absorption. However, the Anjasmoro and Wilis varieties demonstrate better adaptability compared to Malika and Detam 1, as evidenced by their superior growth and yield. This suggests that Anjasmoro and Wilis have a higher capability to adapt to the challenging conditions of coastal land. Therefore, these two varieties are recommended for cultivation in coastal areas to boost soybean productivity, ensuring the sustainability and stability of the national food supply.

Abstract

This study investigates the spatial dynamics of social vulnerability to tsunami hazards in Bengkulu City by applying the BNPB (2012) framework as a national reference for index-based assessments. Five key social indicators: population density, gender ratio, poverty, disability, and age were analyzed using spatial techniques and secondary socio-demographic data to identify spatial disparities in vulnerability across sub-districts. The findings reveal that Teluk Segara and Ratu Samban Sub-Districts are the most socially vulnerable areas, driven not only by high population density and poverty but also by their low-lying coastal topography, direct exposure to the Indian Ocean, and limited evacuation accessibility. In contrast, inland sub-districts such as Selebar and Singaran Pati demonstrate lower vulnerability levels due to their higher elevation and greater distance from the coast. These spatial variations indicate that social vulnerability in Bengkulu City is strongly influenced by the interaction between socio-economic vulnerability and oceanographic conditions. The study emphasizes the importance of integrating social and oceanographic dimensions into tsunami risk assessments to better reflect site-specific realities and support more effective mitigation planning.  Teluk Segara and Ratu Samban Sub-Districts need to be a priority for targeted preparedness efforts, improved evacuation infrastructure, and the restoration of coastal ecosystems is essential to reduce tsunami impacts. The results contribute to advancing integrated coastal disaster risk management in Indonesia by reinforcing the need to link human vulnerability with coastal environmental processes to achieve sustainable and resilient coastal communities.
