Abstract

Melon (Cucumis melo L.) is a plant that has economic value and has been cultivated in several areas of Indonesia with intensive fertilization. The mineral nutrient that is expected to improve the quality of melon growth and fruit is silica. The aim of the research was to improve the growth and melon fruit quality by addition of silica fertilizer. The treatments in this experiment were the application of silica (Novelgro, water soluble) which was carried out on melon plants with silica concentrations of 0.67; 1.33 ppm; and control (without silica). The results showed that silica increased the plant height, leaf area, and diameter of melon fruit. Melon plant with silica treatment of 1.33 ppm had silica content in the high category (>4% Si) which was 5.31% in the skin of the fruit. Moreover, the addition of silica can prolong the fruit storage period in room temperature compared to control.

Abstract

High methane oxidation activity of local isolated methanotrophic bacteria have a potent as methane gases reducing agent while combined with nitrogen fixing bacteria as paddy biofertilizer. The aim of the research was to evaluate the effectiveness of the bacteria as methane gases reducing agent and biofertilizer in paddy plantation. The research was arranged in a completely randomized design consisted of fertilizer types and watering system treatments with four replicates. The research showed that paddy shoot length was not affected by the treatment. On the other hand, both plant freshand dry weight, as well as the number of productive tiller were affected by interaction of fertilizer types and watering system. Fertilizer types affected grain per panicle and methane flux after fertilization. In the end of paddy vegetative stage, bacterial fertilizers were capable to reduce methane emission in different rate. The different result in methane flux was likely due to the interaction between soil local microorganisms and soil chemical component.

Abstract

Keong mas, Pomacea canaliculata, adalah salah satu hama padi di Indonesia. Berbagai penelitian terkait hama tersebut telah banyak dilakukan di Indonesia dan negara lainnya. Untuk memberikan masukan kebijakan berbasis sains, penelitian ini membandingkan basis data penelitian keong mas di Indonesia dan negara lainnya. Analisis menunjukkan tren penelitian keong mas sebagai pakan ternak di Indonesia. Penelitian moluskisida keong mas secara umum lebih populer di dunia. Penelitian bertema keong mas lain di Indonesia masih perlu dilakukan bersamaan dengan peningkatan kualitasnya, seperti penggunaan metode eksperimen dan analisis terkini. Selanjutnya, perlu dilakukan upaya peningkatan partisipasi masyarakat dalam manajemen informasi distribusi keong mas dan kearifan lokal penanganannya. Hal-hal tersebut dapat menjadi dasar untuk formulasi penelitian lanjutan, kebijakan, dan manajemen keong mas berkelanjutan.

Abstract

Mutualistic plant-microbe interaction can increase the availability or absorption of nutrients and affect plant metabolism. Metabolomics is the study of all metabolites contained in living beings at a specific time. This research aims to study the effect of metanotrophic bacteria (BGM 9 isolate) and nitrogen-fixing bacteria (ITJ 7 isolate) on rice plant growth and reveal the information about metabolites produced by rice plant interacting with the bacteria. Three rice plant varieties (Ciherang, Hawara Bunar, and IR64) were grown on liquid media (Yoshida solution) and were inoculated with the bacteria five weeks after planting. Metabolites in the liquid media were detected seven days after inoculation using Liquid Chromatography-Mass Spectrometry and analyzed using MassLynx v4.1. The results showed that the bacterial inoculation had significant effect on rice growth. Chromatograms resulted from LC-MS showed there are 34 unique peaks from Ciherang, 21 unique peaks from Hawara Bunar, and 30 unique peaks from IR64. The unique peaks in each variety were affected by the bacteria inoculation treatments.

Abstract

Oil palm requires sufficient water for optimal growth. However, oil palm plantations in Indonesia face the challenge of global climate change, which causes increased temperatures and unpredictable rainy seasons. The research aimed to analyze oil palm accessions from Jambi that are tolerant to drought based on plant morphophysiological characteristics and metabolite profile. The experiment was conducted in the greenhouse using a factorial randomized block design. Five oil palm accessions were evaluated in this study, i.e., Muara Jambi (MJ), Tebo (TB), Tanjung Jabung Barat (TJB), Merangin (MR), and Simalungun (SM). Seedlings were planted in pots containing 20 kg of soil and acclimatized for 14 days before treatment. Drought treatments were carried out for two, four, and six weeks. Observations were made on growth, physiological, and metabolite changes at the end of each drought period. The study showed that the SM accession exhibited a higher photosynthetic rate and fresh and dry biomass than the other accessions. However, the content of proline and MDA increased significantly in oil palm throughout the drought periods. Metabolomic profiling revealed a significant increase in 13 metabolites under drought stress, i.e., citramalate, L-tyrosine, ferulate, and 3-4-dihydroxybenzoate were the four most prevalent metabolites in the leaf. The root produced more L-proline, aspartate, aconitate, kaempferol-3-o-pentoside, oxoadipate, citrate, L-phenylalanine, maltose, phenylacetic acid, and citramalate. These metabolites have roles in plant metabolic pathways such as valine, leucine, and isoleucine biosynthesis, phenylpropanoid biosynthesis, arginine and proline metabolism, citrate cycle (TCA cycle), lysine biosynthesis, phenylalanine metabolism, and starch and sucrose metabolism.
