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

Mechanical harvesting in cayenne pepper is developing, however, factors affecting canopy architecture and fruit characteristics are still lack. Study aimed to evaluate the effect of shade intensities on canopy architecture and fruit position in cayenne pepper to support developing smart harvesting tools. The experiment was conducted in Babakan Sawah Baru Experimental Farm, IPB from September 2021 to March 2022. The experiment used nested design with shade levels (no shade, 25%, 30%, 50%, 60%, 90%, and 100%) as the main plot and time of shading application (4, 6, 8, and 10 weeks after planting) as sub-plot. The canopy architecture and fruit position were affected by the shade level and its time application. Plant height increased and the canopy widened with increasing shade levels up to 50%. Thus, the shading level should be considered in the development of smart harvesting methodology. Keywords: cabai rawit, climate change, labor, low light intensity, plant architecture

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

Amomum compactum (Javanese cardamom) is valued for its unique flavor and aroma, commonly used as a culinary spice or medicinal ingredient. The numerous accessions of cardamom in Indonesia present a significant potential for developing this spice. However, the specific potential of each accession remains to be discovered. This study records the variation of agronomical traits and metabolomic profiles of nine cardamom accessions from Central Java, Indonesia. Multivariate analysis using a heatmap on agronomical traits indicated significant variation among accessions, with clustering based on growth locations. Genetic parameter analysis revealed high phenotypic variability, but varying broad-sense heritability among traits, suggesting the influence of both genotypic and environmental factors. Metabolomic analysis using GC-MS reveals the presence of specific compounds in certain accessions, such as beta-panasinsene in the Kulonprogo Putih accession, 1-docosene and alpha-terpinene in the Banyumas Putih accession, and 9-tricosene in the Banyumas Hybrid, which can serve as markers for these accessions.
