Abstract

The intensive application of organophosphate pesticides containing profenofos as the active compound may lead to soil contamination and the emergence of pesticide-tolerant bacterial strains with potential for bioremediation. Comprehensive identification and characterization of these bacteria are crucial to support sustainable agricultural and environmental management practices. The aim of the study is to analyze the characteristics and identify indigenous bacteria tolerant to profenofos pesticide in Sleman agricultural land, DIY. This study is qualitative research using an exploratory-descriptive. Isolation was carried out by dilution to a level of 10-7 followed by a spread plate on Mineral Salt Medium (MSM) which was given with 100 ppm profenofos pesticide. Bacterial isolates were characterized and then identified using profile matching with reference genera. Based on the results of the study, it is found that 10 bacterial isolates tolerant to organophosphate pesticide with the active ingredient profenofos that have a similarity index of ≥70%. Based on the reference bacteria, 5 different genera are obtained, namely Paracoccus (D3, D8), Micrococcus (D5, D6, D9), Enterococcus (D2, D10), Arthrobacter (D1, D4), and Neisseria (D7). The bacterial isolates obtained have different characteristics. The characteristics of these bacteria are gram positive and negative bacteria with round, irregular, and rhizoid shapes. Their margins are lobate, curled, entire, undulate, and ciliate. Their elevations are umbonate, raised, and flat. The color of the bacteria is white to light orange, with various physiological test results.

Abstract

Gold is a fairly large contributor to Indonesia's foreign exchange. The area that has the potential to have minerals is Banyumas Regency. This area has been indicated to have gold mineral reserves of around 16,000 hectares. Until now, the gold processing process still uses mercury, which produces negative impacts such as post-mining waste containing heavy metal mercury (Hg), which can cause environmental damage. Environmental damage that arises, such as pollution of the soil and water environment, due to the gold bioleaching process that is disposed of without any treatment. One alternative that can be used to overcome this problem is by using hyperaccumulator plants. One plant that falls into the hyperaccumulator category is the bandotan plant (Ageratum conyzoides), because it is often found in gold mining areas contaminated with mercury. Mercury contamination will be absorbed from the environment into the body of Ageratum conyzoides through membranes and converted into less toxic substances. The aim of this research is to determine the ability of the Ageratum conyzoides plant as a phytoremediation agent in reducing mercury metal (Hg) in tailings from Paningkaban Village, Banyumas. There are two treatments, namely the planting media used with 2 kg of tailings soil and 2 kg of planting media mixed with tailings and compost. The mixture ratio between tailings and compost is 1:1. Each treatment, consisting of three replications, was observed using plant growth parameters (plant height and number of leaves), as well as control parameters (edaphic and microclimatic). The results of the research show that the Ageratum conyzoides plant is a phytoremediation agent that can reduce levels of the heavy metal mercury (Hg) in the planting medium of mining tailings soil from Paningkaban Village, because it gives test results of BCF values > 1 and TF < 1, which indicates that the Ageratum conyzoides plant has potential as a phytostabilizing agent.

Abstract

To solve problems accurately and focused, students must have problem solving skills. The purpose of this study was to evaluate class X students of SMA N 4 Yogyakarta in the even semester of the academic year. This study uses a descriptive quantitative research method. As a sample used simple random sampling. According to Polya, there are four indicators of problem-solving ability: Understanding the problem, preparing, implementing plans, and re-checking are steps that must be taken. On the topic of environmental change, the test instrument revealed that students' problem-solving abilities were in the high range. But if we look at each indicator separately, we can see that all four of them belong to a group. This is because students do not double-check their written answers and continue to doubt these answers. The non-test instrument study, on the other hand, the non-test instrument study found that students' problem solving abilities were very good. Based on these findings, it can be concluded that the students' overall problem solving abilities are of a high standard. Because research findings cannot be used with all materials, problem solving skills must be tested with different materials.

Abstract

Karangmalang and Kuningan are the area located near the campus ofYogyakarta State University and Gadjah Mada University. This causes the twoareas have crowded population. Many students from outside of Sleman Yogyakarta stay in many boarding houses that need laundry service since they do not have enough time and are very busy of studying activities. There are approximately 30 laundry service businesses in these areas. The condition has positive impact on local people income generating. However, it also cause adverse effects on the environment because of the laundry waste water directly discharged into the environment without prior treatment. The priority problem to solve is the disposal of waste water and dissemination of eco-friendly detergen. We had "Sekar Laundry" and "Ramadhani Laundry"as our partners in this programme. To achieve the objectives of the project we carried out the following methods: (1) socialization, counseling, and training for the introduction of ecofriendly detergents and simple sewage treatment; and (2) the application of appropriate technology of waste water treatment based on fitoremediation for both partners. The results obtained were in accordance with the purposes. We could overcome the environmental pollution caused by waste water of laundry activities. Based on laboratory tests, laundry waste water from the outlet of the Waste Water Treatment Plant (the WWTP) had significantly quality improvement that it made safer to be discharged into the environment, with 27,125% of BOD decline efficiency, 120,350% of COD decline efficiency, 17,300% of TSS decline efficiency, 11,597% of detergent decline efficiency, and 88% of phosphate decline efficiency
