Abstract

Soybeans are among the best plant-based sources of protein. However, a high intake of rich potassium legumes such as soybean could have negative impacts on people who are sensitive to high potassium. A study on NPK stoichiometry of the most popular Indonesian soybean varieties was conducted as a preliminary evaluation to develop low-potassium soybeans. The experiment was conducted at Cikabayan Experimental Station, IPB University, from January to April 2024. The field experiment was arranged in randomized block design using 12 soybean varieties: “Anjasmoro”, “Deja 2”, “Dena 1”, “Dering 1”, “Denasa 1”, “Denasa 2”, “Dering 3”, “Devon 1”, “Devon 2”, “Grobogan”, “Mallika”, and “Slamet”. Results showed that “Slamet” produced the highest stover while “Anjasmoro” was the lowest. “Slamet”, “Dering 1”, and “Mallika” produced the highest bean production per hectare (3.75-4.73 t ha- 1). N uptake was higher than P, and K. Seed of “Dena 1” had the lowest K content, while the highest was “Denasa 1”. The stoichiometric ratios of N/P, N/K, P/K showed different values according to varieties. Thus, decreasing the K level in seed could be done by selecting a low K variety.

Abstract

Realizing sustainable urban agriculture is one of the sustainable development goals (SDGs) targets that must be achieved. This research was conducted to analyze and explain environmental risk control for the development of sustainable urban agriculture. The research location was in East Jakarta, one of the cities in Indonesia that has implemented urban farming practices. Identification of urban agricultural environmental risks caused by biotic and abiotic factors determined of 17 categories of questions that can be represented in this research. Three risk assessment scales were used, low, medium and high risk. The environmental risk of urban agriculture caused by biotic and abiotic factors was found to have the highest risk in the air dust category. Based on the research results, it was concluded that, in general, respondents had quite effective knowledge of environmental risks but needed to increase their knowledge and deeper understanding of creating sustainable urban agriculture. Urban agriculture, due to its social, economic, and environmental benefits, should be considered part of a dynamic urban system during planning and implementation.

Abstract

The manual and time-consuming nature of current agronomic technology monitoring of fertilizer and irrigation requirements, the possibility of overusing fertilizer and water, the size of cassava plantations, and the scarcity of human resources are among its drawbacks. Efforts to increase the yield of cassava plants > 40 tons per ha include monitoring fertilization approach or treatment, as well as water stress or drought using UAVs and deep learning. The novel aspect of this research is the creation of a monitoring model for the irrigation and fertilizer to support sustainable cassava production. This study emphasizes the use of Unnamed Aerial Vehicle (UAV) imagery for evaluating the irrigation and fertilization status of cassava crops. The UAV is processed by building an orthomosaic, labeling, extracting features, and Convolutional Neural Network (CNN) modeling. The outcomes are then analyzed to determine the requirements for air pressure and fertilization. Important new information on the application of UAV technology, multispectral imaging, thermal imaging, among the vegetation indices are the Soil-Adjusted Vegetation Index (SAVI), Leaf Color Index (LCI), Leaf Area Index (LAI), Normalized Difference Water Index (NDWI), Normalized Difference Red Edge Index (NDRE), and Green Normalized Difference Vegetation Index (GNDVI).

Abstract

Indonesia has significant potential for food diversification through the development of sago as an alternative carbohydrate source. This study aims to analyze the processing methods, morphological characteristics, chemical properties, and heavy metal content of local sago in Bangka and Bangka Tengah Regencies. The research was conducted across six villages from November 2023 to March 2024, with chemical and heavy metal testing performed in accredited laboratories. The results indicate that modern processing methods produce high quality starch with a starch content ranging from 79.06% to 83.73% and heavy metal levels such as tin (Sn), lead (Pb), and cadmium (Cd) below the established safety limits, making it safe for consumption. Morphologically, habitat differences influence the physical characteristics of sago, such as trunk height, bark thickness, and leaf area, which affect starch productivity. The study also identifies that environmental factors, including nutrient availability and soil moisture levels, influence the chemical composition of sago. This research provides a scientific foundation for the integrated management of sago, supporting national food diversification efforts and opening opportunities for the development of sago based products that meet national quality standards (SNI) with an environmentally friendly approach. These findings are relevant for stakeholders in optimizing sago's potential as a strategic commodity contributing to national food security. Keywords: Food diversification, Heavy metal, Sago, Starch content, Sustainable agriculture.

Abstract

Cassava, an essential staple food with diverse applications, has been relatively underexplored in terms of health analysis using vegetation indices. Conventional field surveys face challenges in covering large areas due to resource constraints. Recent advancements in remote monitoring techniques, such as satellite imagery and Unmanned Aerial Vehicles (UAVs), offer a promising alternative. While satellite imagery enables broad-scale surveys, its limited spatial resolution restricts detailed analyses of individual plants or smaller ecosystems. UAV-based vegetation surveys commonly utilize Vegetation Indices (VI) to assess unique spectral information. This study investigated UAV-based methods for mapping cassava distribution in the Telaga Kahuripan smallholder plantation in Bogor, Indonesia, focusing on UAV imagery, segmentation, and vegetation indices to evaluate cassava plant health at 2, 5, and 8 months of age. The results revealed significant variations in vegetation indices across different cassava plant ages. Particularly, the highest values observed at 5 months of age indicated substantial growth, with NDVI and GNDVI values exhibiting R2 ranging from 0.95 to 0.98, indicating a strong correlation. The robust correlation between NDVI and GNDVI implies that both indices can effectively predict plant health using UAV-based monitoring. Comparisons with existing studies suggest potential variations attributable to factors such as geographical location, environmental conditions, and cultivation practices. Understanding these variations is crucial for refining monitoring techniques and informing agricultural practices. Consequently, the findings have implications for enhancing cassava health monitoring and optimizing agricultural practices to ensure sustainable crop production.

Abstract

 Indonesian strawberry quality is generally still low leading to high strawberry imports. Research aimed to evaluate the effect of Boron (B) and Molybdenum (Mo) applications on the production and quality of strawberries. The research was conducted at a farmer’s field in Rancabali-Bandung, Indonesia, from July to August 2024. Formulated foliar fertilizer containing 500 ppm B and 5 ppm Mo was applied with different concentrations (0%, 0.5%, 0.6%, 0.8%). It was applied at different fruit stages (5 and 12 days after anthesis). Data were evaluated for the number of fruits, fruit size and weight, and fruit quality. Results showed that application time at different fruit ages had no significant effect on all variables. Fertilizer concentration did not affect fruit production, but it affected fruit firmness, TTA, and TSS levels. The concentration of 0.8% resulted in the highest level of firmness, the lowest TAA level (0.32%), and the highest TSS (12.40 oBrix). Thus, the B and Mo applications enhanced some indicators of fruit quality in strawberries. It is important to evaluate the effect of B and Mo applications at the farmer’s level to enhance strawberry quality.  Keywords: Acidity, Brix, foliar fertilizer, production, vitamin C
