Published: February 2023

This study aims to determine the ability of watercress plants in absorbing mercury (Hg). Mercury is one type of heavy metals dangerous and toxic (Hakim, 2003). If the amount in the water has crossed the threshold will cause pollution. For that required effort to minimize the levels of Hg metal before the waste into the waters, such as by using watercress plants as phytoremediation agent. Research was conducted experimentally. The purpose of this study is to know the ability of watercress in accumulating mercury in water media.Phytoremediation media in the form of HgNO3 solution with concentration 0,5 and 1 ppm and addition of NPK 1 gram in insert plastic container as much as 1 liter. Measurements of Hg concentration in plants were performed on day 5, 10, 15 using SSA. The resulting data is processed using qualitative method of descriptive. The result showed that there was no accumulation of mercury in watercress concentration of 0,5 and 1 ppm during exposure 5, 10, 15 days, and concentration 5 ppm during exposure 5 and 10 days, but accumulated at concentration 5 ppm for 15 days exposure that is equal to 0,116 ppm, therefore watercress is still safe from mercury at low concentration of 0,5 and 1 ppm, but dangerous at concentration of 5 ppm.

Endophytes are microbes (bacteria, fungi, or actinomycetes) that live and colonize the host tissue without causing negative effects, even giving benefits to the host. One of the advantages is as a biological control agent for both insect pests and pathogens that cause plant diseases. As a biological agent, endophytes can reduce plant damage by insects, nematodes, or pathogens that cause disease through induction of plant resistance. In addition, endophytes can also function as biological agents through antagonistic interactions and competition. The purpose of this study was to obtain endophytic fungi which are potentially as biological agents of insect pests; the mechanism, as well as the application of endophytes in plantation crops. The potential of enndofit fungus in controlling Fusarium sp carried by soybean seeds was also tested.

Published: February 2023

Bryophyte is a non-vascular plant, consisting of three classes: mosses, hornworts, and liverworts. The body forms have a thallus, and some have a leaf-like organ. The class division of the Bryophyte division is base on anatomical and morphological traits, such as meristem tissues, stomata, and vascular tissues. M Bryophyte has no vascular tissue, but it has a capillary that has functions like xylem and commonly refers to as hydroid. Mosses and hornworts have stomata on the sporophyte part, while in the liverworts, stomata are not found. Hornworts have a basal meristem that has an unpredictable cleavage. Meristem on the mosses only divides up the formation of sporangial. In the liverworts, the apical meristem does not see. Members of the hornworts consider the most advanced because the meristematic phase is more prolonged, so that it is closer to the characteristics of Tracheophyta group.

Rhizosphere bacteria live in the soil around plant roots. Various rhizosphere bacteria are able to produce the hormone Indole-3-Acetic Acid (IAA) which stimulates plant growth. This study aims to isolate and characterize IAA-producing rhizosphere bacteria in rice plants in the rice fields of Kedungpani urban village, Semarang city. Bacterial enumeration was carried out using the total plate count (TPC) method. The isolates obtained were characterized by observation of colony and cell morphology, gram staining, endospore staining, catalase test, and sugar fermentation test. The ability to produce the IAA hormone was tested using Salkowski's reagent. The enumeration results showed that the total bacteria in the sample was 2.9 x 105 CFU / g. A total of 10 isolates were obtained and were able to produce the IAA hormone with various concentrations. Isolates KP1, KP2, KP3, KP4, KP5, KP6, KP9, KP13, KP14, and KP15 produced IAA with concentrations of 3.389, 5.111, 3.000, 1.667, 1.944, 5.056, 5.444, 4.500, 5.056, and 10.833 ppm, respectively. The results showed that there were 5 isolates with the highest IAA concentrations, namely KP2, KP6, KP9, KP14, and KP15 which had the potential to be used as biostimulant agents for plants.
