Abstract

Background: Air pollution is a threat to the environment. Sources of air pollutants in urban environments can be in the form of dust, heavy metals, and hydrocarbons. Plants can help clean air pollutants from the atmosphere by absorption through the stomata, accumulating them, or by adsorption on the leaf surface. The Air Pollution Tolerance Index (APTI) is used as an evaluation benchmark for the Physiological conditions of plants exposed to air pollution. This research aims to study the physiological conditions of six tree species in air conditions in the Depok City area and to assess the plants' tolerance level based on the APTI calculation. Methods: The physiological parameters measured to calculate APTI were ascorbic acid, total chlorophyll, leaf extract pH, and Relative Water Content (RWC). The six tree species used as objects in this study were Artocarpus altilis, Artocarpus heterophyllus, Bauhinia purpurea, Ficus septica, Filicium decipiens, and Nephelium lappaceum. Results: Differences in the physiological conditions of six tree species in the Depok City area based on the average ascorbic acid values, total chlorophyll, leaf extract pH, and RWC. In addition, there are also differences in APTI parameters between the two research locations. Conclusions: Filicium decipiens is the plant species with the highest APTI, while Artocarpus heterophyllus has the lowest. Based on the APTI scores, Bauhinia purpurea, Ficus septica, Filicium decipiens, Nephelium lappaceum belong to moderately tolerant category, Artocarpus altilis belongs to an intermediate category, Artocarpus heterophyllus belongs to sensitive category.

Abstract

Background: The learning process emphasizes students' active involvement and is oriented towards applying the concept of learning by doing and prioritizing personal experiences through observing, asking, and communicating to increase student creativity. However, reality proves that the application and implementation of learning in schools are not as expected. Some problems include the learning process only focusing on completing the subject matter, not on forming an understanding of the subject matter for students. This study aimed to analyze the need to develop electronic teaching materials according to the needs of students based on problem-based learning (PBL) learning models in biology subjects at MAN 1 Palembang school. Methods: The research used a qualitative descriptive method with a survey method by conducting interviews and questionnaires with biology teachers and students. Questionnaires, observations, and interviews provided data collection techniques. Results: The results obtained are textbooks and learning videos are the teaching materials most often used by teachers using discovery learning and project-based learning (PjBL) models. Students' activeness can be seen when the discussion activities and presentations of assignments take place, but it does not make students think critically. Conclusion: Teachers want problem-based learning (PBL) electronic teaching materials so that students can learn the material earlier and improve learning outcomes in material that is difficult for students to understand.

Abstract

Background: Brown Oyster Mushroom (Pleurotus cystidiosus) is a type of mushroom that has different advantages from other oyster mushrooms. Generally, farmers make planting media for brown oyster mushrooms made from sawdust of sengon wood. The availability of raw materials for sawdust of sengon wood is increasingly difficult to obtain. So we need other alternative materials as a source of nutrition, one of which is banana stem waste. This study aims to determine the effect of banana stem flour on the diameter of the cap, the number of fruiting bodies, and the wet weight of the fungus. Methods: This study used a completely randomized design (CRD) which consisted of one factor. This study used 4 treatments and 3 replications. Data was tested by quantitative descriptive analysis using the Analysis of Variance (ANOVA) test. Results: Banana stem flour has a significant effect on all parameters. The JM2 treatment resulted in a cap diameter of 10.3 cm, mushroom fruiting bodies of 10.6 and wet mushroom weight of 103.8 g. Conclusion: The addition of banana stem powder can increase productivity in the parameters of mushroom cap diameter, number of mushroom fruiting bodies, and wet weight of mushrooms, which can be used by readers or researchers. Utilization of waste such as sawdust of sengon wood and waste of banana fronds for the cultivation of brown oyster mushrooms is one way of handling plantation waste.

Abstract

Background: A public burial place (TPU) is used to bury the dead. There is an active decomposition of corpses in the soil, which produces soil nutrients and minerals that can support the growth of microorganisms in the ground, including pathogenic bacteria. Pathogenic bacteria have a more severe impact if they are resistant to antibiotics. Methods: Soil samples were taken in the Bonoloyo TPU area, Surakarta, Central Java, at 3 points each of 2 depths of 20 and 50 cm. Soil samples were inoculated on NA (Nutrient agar) media using the spread plate method. After 48 hours, colony counting and morphology observations were carried out, followed by gram staining. Isolated bacterial isolates were tested for resistance to 3 types of antibiotics. Results: The average population of soil bacteria in blocks 12, 17, and 21 at a depth of 20 cm is 4 x 10⁶ CFU/g; 8 x 10⁶ CFU/g; and 1 x 10⁶ CFU/g, while at a depth of 50 cm, it is 2.3 x 10⁶ CFU/g; 6 x 10⁶ CFU/g; and 4 x 10⁶ CFU/g. The morphology of bacterial colonies is irregular (26 isolates), flat elevation (19 isolates), and the color of isolates is predominantly white. The Gram staining results obtained 23 isolates are Gram-negative, and 22 are Gram-positive with a dominant cell form in cocci. Antibiotic resistance tests showed that the bacterial isolates were resistant to ampicillin (28.9%), Bacitracin (64.4%), and Cefepime (57.8%). Conclusions: Burial soil bacterial populations at Bonoloyo TPU at different depths did not differ markedly, with numbers ranging from 1 - 8 x 10⁶ CFU/g.

Abstract

Background: A public cemetery (TPU) is where bodies are buried. Before being buried, the body is wrapped in a shroud or full clothes and sometimes put in a coffin. These materials contain cellulose, a substrate for cellulolytic microorganisms, including bacteria, to decompose. Exploration of cellulolytic bacteria in TPU has not been found, even though TPU holds potential cellulolytic bodies. This study aims to determine the cellulolytic potential and identify bacterial isolates from TPU. Methods: 36 bacterial isolates tested for cellulolytic potential have been isolated from TPU Pracimaloyo Kartasura, Sukoharjo. Selection of cellulolytic bacteria used selective Carboxymethyl Cellulose (CMC) media dripped with Congo red 0.1%, while identification was based on colony morphology and Gram staining. Results: This study obtained one isolate (2.78%) showing high cellulolytic activity with a cellulolytic index (IS) 7, namely P14, 24 isolates (66.67%) in the "moderate" category, four isolates (11.11%) with category "low," and seven isolates (19.44%) did not show cellulolytic ability. Isolates cellulolytic positive have a shiny white colony color, entire edges, raised elevation, and belong to the Gram-negative coccus form. Conclusions: From the results of this study, it can be concluded that public burial sites (TPU) harbor potential cellulolytic bacteria.

Abstract

Background: Plants’ response and antagonistic reaction against disease-causing organisms are two crucial characteristics of Plant Growth Promoting Bacteria (PGPB). Seventeen endophytic bacteria have been isolated from Musa balbisiana. However, the plants’ reaction against these isolates and their antagonistic activities against disease-causing organisms remained unknown. This study aims to (1) determine the sensitivity effect of endophytic bacteria isolates to tobacco and (2) test the antagonism of endophytic bacteria isolates against the blast disease actor, namely Pyricularia oryzae. Method: Sensitivity tests were performed by inoculating bacterial isolates into tobacco leaves with infiltration. Bacterial isolates were prepared with a minimum OD 600: 0.5. Then, a milliliter volume of each isolate was infiltrated into tobacco leaves from the abaxial side using a 3 mL syringe. The lesion on the tobacco leaves was observed seven days after inoculation (DAI). The antagonism test was carried out by growing Pyricularia oryzae on a PDA plate for seven days, subsequently transferred to an NA medium for three days then inoculated with endophytic bacteria. The assessed parameter of the antagonistic test was the formation of an inhibitory zone between endophytic bacteria and Pyricularia oryzae at 4 DAI. Results: No hypersensitive reaction of tobacco leaves against K117, K324, K38, K86, K18, K28, K102 isolates inoculation at 7 DAI. Furthermore, the antagonistic test indicated that all isolates inhibited the growth of Pyricularia oryzae, with the range of inhibition from 32.36 to 40.46%. Implication: Thus, these results revealed the PGPB characteristics in the newly isolated endophytic bacteria from the banana.

Abstract

Background: Liquid organic fertilizer is a fermented solution of organic plant residues, animal and human feces containing nutrients. Lamtoro and tofu liquid waste contain N, P, K, Mg, and Ca, which are suspected to have the potential for liquid organic fertilizer to increase the growth of cayenne pepper (C. frutescens). This study aims to determine the effect of giving POC from lamtoro leaves and tofu liquid waste on the growth of cayenne pepper (C. frutescens). Methods: This study used a completely randomized design (CRD) with two replications. POC volume 1:1 consisted of two-liter lamtoro leaf extract and 2-liter tofu liquid waste. The first factor is the volume concentration of POC with the respective concentrations of V0: 0%, V1: 10%, V2: 20%, and V3: 30%. The second factor is the time of spraying POC T1: 3 days interval and T2: 6 days interval. Parameters measured included plant height (cm), number of leaves (strands), and plant fresh weight (g). Results: 20% volume (V2) with three-day intervals (T1) gave the best results for plant height (20.10 cm), number of leaves (7.00 leaves), and plant fresh weight (11.50 g). 0% volume (V0) with an interval of 6 days (T2) gave the lowest yield on plant height (6.35 cm), number of leaves (3.00 leaves), and fresh weight of plants (3.00 leaves). Conclusions: Application POC from lamtoro leaves and tofu liquid waste can potentially increase the growth of cayenne pepper (C. frutescens).
