Abstract

Plumbum or lead is a type of heavy metal that is dangerous if it has exceeded the threshold of 0.07 µg/g based on the National Standardization Agency SNI 2004. This type of heavy metal is found in nature such as in soil, water, and air. The purpose of the study was to determine the phytoremediation ability of two types of ornamental plants, namely Celosia argentea L. and Mirabilis jalappa L., against Plumbum (Pb) metal in soil. The growth parameters observed consisted of plant height, plant stem diameter, number of leaves, leaf length, and leaf width. The ICP-MS (Inductively coupled plasma-mass spectrometry) was used to analyze the plumbum (Pb) content in soil and plants. The results ofinitial soil analysis prior to the plant planting process (phytoremediation) were 103.17 µg/g which had exceeded the predetermined threshold. The result of the analysis after phytoremediation of Celosia argentea L. showed plumbum (Pb) content of 49.685 µg/g in soil and 1,9548 µg/g in plants. Similarly, the analysis of Ph content after phytoremediation of Mirabilis jalappa L. was 47.802 µg/g in soil and 5.3077 µg/g in plants. Based on biomass calculation of Celosia argentea L. and Mirabilis jalappa L., the obtained Plumbum (Pb) content was 18.84% and 27.85%, respectively. The percentage of Pb removal of Celosia argentea L. was 51.842%, while Mirabilis jalappa L. was 53.667%. The efficiency of Pb absorption of Celosia argentea L. and Mirabilis jalappa L. was 1.895% and 5.145%, respectively. In conclusion, Ornamental plants Celosia argentea L., and Mirabilis jalappa L., are able to act as phytoremediation agents for Plumbum (Pb) metal that pollutes the soil as evidenced by the decrease in Pb levels in the soil after the phytoremediation process.Keywords: Plumbum (Pb), Phytoremediation, Celosia argentea L., Mirabilis jalappa L.

Abstract

One of the most promising agricultural commodities is the cultivation of mangoes. One way that can be used to maintain the quality and freshness of the fruit in a simple way is to do an emulsion coating. The purpose of this research was to determine the effect of citronella oil and sesame oil emulsion coating on the quality and storability of mango (Mangifera indica L.). The method used in this study was a Completely Randomized Design (CRD) with two factorial treatments and controls. The first factor was citronella oil under a concentration of 0.5% and 1%. The second factor is sesame oil under a concentration of 0.5% and 1%. The two oils were combined in the emulsion into three treatment combinations, namely S0W2, S2W0, and S1W1. The parameters measured in the observations were hardness, damage, and glucose levels in the fruit. The results showed that the level of hardness of mangoes decreased in the four treatments. Then it was found that there was an effect of delaying the maturity of the fruit with the S1W1 treatment because it was not damaged like the other treatments. While glucose levels in the fruit have increased due to the ripening process. Coating treatment with a ratio of citronella oil concentration of 0.5% to 0.5% sesame oil is the most effective treatment combination in maintaining quality and shelf life because this treatment can delay damage to mangoes.

Abstract

This research is an experimental study that aims to determine the effect of the application of N2-fixing bacteria Actinomycetes, Azospirillum, and Azotobacter on the vegetative growth parameters of corn plants and on the nitrogen content of corn plants. Parameters for measuring the growth of corn plants include: formation rate of radicle length, plant height, number of leaves, leaf length, fresh weight of plants, fresh weight of plant roots, dry weight of plants, dry weight of plant roots, total N content in plants, as well as physical and chemical qualities of the ground. Experiments on the application of N2 -fixing bacteria on corn plants on a laboratory scale were carried out to determine the in vitro effect of microbes on corn seeds. The pot test was carried out to determine the effect of N2-fixing bacteria on the vegetative growth of corn plants in vivo. Data were analyzed using ANOVA with Duncan's test. The results showed that corn plants inoculated with Actinomycetes, Azospirillum and Azotobacter showed a significant different growth from corn plants without nitrogen fixing bacteria, namely formation rate of radicle length, plant height, number of leaves, leaf length, fresh weight, dry weight, total N content (%) of crops, and soil physical and chemical quality. It can be concluded that the inoculation of nitrogen-fixing bacteria in corn plants has a significant effect on plant vegetative growth parameters and plant nitrogen content.Keywords: Nitrogen fixing bacteria, Actinomycetes, Azospirillum, Azotobacter, Plant vegetative growth.

Abstract

The canals in the center of Sanggau City, West Kalimantan serve as a medium for wastewater which enters the Kapuas River. The density of community activities in this city has caused indications of its canals being polluted by organic and inorganic materials. These contaminants enter the canal continuously, hence its accumulation can change the texture of the substrate/sediment which is the habitat for aquatic Oligochaete. The purpose of this study was to identify and describe the types of aquatic Oligochaete in the canals of Sanggau City. The research was conducted from August to September 2020 using the purposive sampling method at five stations, namely Tanjung Sekayam Village, Ilir Kota Village, Beringin Village, and Bunut Village, with three replications at each sampling station. The results showed that aquatic Oligochaete at the canals of Sanggau City consisted of 1 order, 1 family, 2 genera, and 3 species with a total of 1367 individuals. The identified species are Branchiura sowerbyi, Limnodrilus claparedeianus, and Limnodrilus hoffmeisteri.Keywords: Species Identification, Aquatic Oligochaeta, Sanggau City Canal
