Humic Acid for Reducing Carbofuran Content of Rice Grown in Carbofuran-Contaminated Soil
Full text linkCarbofuran insecticide widely used in rice production. The carbofuran residue in agricultural threatens wide life and human health since its active ingredient carbamate is toxic. Humic acid (HA) amendment is an effective way to minimize the residue in soil since HA can adsorb the organic pollutant and induce growth of fungus that degrade the carbofuran. The objective of this research was to observe the influence of HA on the carbofuran residues in soil, straw, and rice; as well as yield of paddy (Oryza sativa L.) grown in carbofuran contaminated potted soil. The level of carbofuran residue in soil before experiment was 10 mg kg-1. The experiment was setup in Randomized Block Design to test various HAs extracted from organic matter. The results indicated that humic acid didn’t affect plant growth and yield but decreased the carbofuran residue in straw and unhusked rice grain. Rhizosphere of rice treated with HA showed higher fungal count than control. This experiment suggests that HA were effectively used to control the carbofuran residue in soil and rice grown in low carbofuran-contamination agricultural soi

Pengaruh Stres Kekeringan terhadap Pertumbuhan dan Kandungan Sinensetin Tanaman Kumis Kucing (Orthosiphon aristatus (Blume) Miq.)
Full text linkThe response of plants to environmental stress depends on the type of plant, the level, and the duration of stress. Drought stress affects growth, development, and the content of secondary metabolites produced by the plant. Kumis kucing (Orthosiphon aristatus (Blume) Miq.) is one example of a tolerant plant to drought stress. A study was conducted to compare the effect of several drought stress levels on plant growth and its sinensetin content. For this purpose, the experiment was carried out in a greenhouse with a one-factor complete randomized design, namely the level of water availability. The treatment tested consisted of: 100; 50; 37.5; 25; 12.5 percent of field capacity. Data were analyzed using analysis of variance and further tested with the Duncan Multiple Range Test level of 5% on significant results. The High-Performance Liquid Chromatography method was employed to test the sinensetin content (in percentage). The results showed that low water availability (50-12.5% field capacity) harmed plant growth and negatively affected leaf, stem, and root dry weight. The reduction in growth was highly significant in plants with water availability of 12.5% of field capacity. In low water availability, the plant that experience drought stress produced greater sinensetin content (0.0133%). Increased sinensetin in drought stress condition is a biochemical and physiological response of plants to unfavourable conditions

Pengaruh Komposisi Media Semai Sistem Tertutup Terhadap Perkecambahan Padi (Oryza Sativa L.) Inpari 32
Full text linkOne of the efforts to facilitate the way of taking rice seeds from the nursery media is to use plastic sacks instead of directly from the soil. To obtain the best planting media, experiments have been carried out on the no tidal swamp Rice Fields, Pemulutan Village (3°05'42.7"S, 104°44'01.7"E), Ogan Ilir Regency, South Sumatra Province from June to August 2022. The design method used was a Randomized Block Design. The treatments tested were four compositions of planting media mixtures, namely a mixture of soil with chicken manure, a mixture of black sand and chicken manure, a mixture of white sand and chicken manure, and black sand. The media composition ratio was 1:1 (V/V). All treatments were replicated three times to obtain 12 units. The seeds used are rice seeds of the Inpari 32 variety. The size of the seeding media made from plastic sacks was 160 cm x 100 cm, and the thickness of the entire planting media composition was 3 cm. The plastic sacks used had a length of 180 cm and a width of 112 cm, and were used as a pad for a rice nursery which were 160 cm x 100 cm, and the thickness of all media compositions was 3 cm. The composition of the four treatments prior to the study showed that the pH was relatively the same (6.9-7.0) and the EC valuesvaried greatly (207-7734 mS), and at 14 day after plant (DAP) there was a decrease in pH to 4.3-5.3 and EC decreased drastically with narrow variations being (170-384 dS/cm). Changes in the chemical properties of the media certainly had an impact on seed germination (70-90%) at 14 DAP of each media, and it turned out that the composiion of the type of planting media had significant effect on sprout height, number of leaves, leaf length and sprout root length. In general, it can be concluded that the best media composition for rice germination is soil and chicken manure
