Abstract

The average temperature of global warming on the earths surface today has increased by 0.74 ± 0:18°C, the increase was due to the increase in the average temperature of the atmosphere, ocean and land earth. Emissions of the most influential on the quality of the air is carbon emissions, especially carbon dioxide (CO2). The CO2 contributes to global warming is 50%. The CO2 gases absorb and reflect radiation emitted waves of the earth, so that the heat will be stored on the surface of the earth. This study aimed to design a data logger system monitoring the level of concentration of CO2 using the oxygen sensor (OOM202), carbon dioxide sensor (MG81), as well as temperature and humidity sensors (DHT22) with microcontroller-based SMS gateway information. The study tested are simulated in the laboratory with electronic testing and testing communication systems. The test results showed good performance with the prototype, the results of monitoring CO2 emissions seen huge levels of carbon dioxide (ppm) is proportional to the output voltage (Vout) is generated. The greater the concentration levels of gas detected by the sensor, the output voltage generated will be greater, than that difference or distinction ADC output between the measured and calculated because of several errors, such as error output ADC ± 2 bits, error rounding conversion of ADC to volt. The measurement results are different, in the closed and open area refers to the measurement parameters are displayed on an alphanumeric display. Measuring system can transmit data via SMS information system with an average response time of less than 1 minute, it depends on the quality of the signal and traffic data from a provider by the user.

Abstract

Telah dilakukan prediksi model adsopsi Mn+2, Cd+2 dan Hg+2 dalam sistem air-sedimen di sepanjang sungai Code, Yogyakarta. Tujuan dari penelitian ini adalah untuk memprediksi model perpindahan ion logam Mn+2, Cd+2,dan Hg+2 dari badan air ke dalam sedimen berdasarkan fenomena adsorpsi isoterm. Selain itu, penelitian ini diharapkan dapat memberikan informasi terhadap rona awal sungai Code, dinamika, dan keadaan ion logam Mn+2, Cd+2 dan Hg+2 di sepanjang sungai Code dari hulu hingga hilir. Berdasarkan data percobaan ternyata perpindahan ion logam Mn+2 dan Cd+2 ke dalam sedimen akan mengikuti model adsorpsi Langmuir, dengan koefisien determinasi (R2) sebesar 0,9929 dan 0,9701, sedangkan nilai energi adsorsinya masing-masing adalah 20,95 kJ/mol dan 16,85 kJ/mol. Perpindahan ion logam Hg+2 ternyata akan cenderung mengikuti model adsorpsi Freundlich. Dari energi adsorsi yang didapat ternyata ikatan untuk ion logam Mn+2 ke dalam sedimen akan berupa kimisorpsi, sedangkan ion logam Cd+2 akan cenderung mengikuti fisisorpsi, dan kekuatan ikatannya dapat diurutkan sebagai Mn+2 > Cd+2 > Hg+2.

Abstract

The ability of plants to absorb metallic pollutants varies. The research has been conducted to compare the effectiveness of Tanjung (Mimusops elengi) and Bungur (Lagerstroemia) plants in absorbing Pb metal in particulate matter. The effect of location and leaf height on the effectiveness of pollutant uptake was also observed. Sampling was carried out in July 2020-September 2020 by taking leaves that were not too dark or light in color. Leaves taken at heights 3, 6, and 9 m on Timoho side Street. The particulate and leaf samples were digested and then analyzed their Pb levels using an Atomic Absorption Spectrophotometer (AAS). The results showed that the Tanjung plants with denser leaves captured more particulate deposits than the Bungur plants. This plant is also more effective at absorbing and accumulating Pb metal, which is indicated by the ratio of Pb metal in the leaves to Pb in particulates which is higher than the Bungur plant. These results were consistent for each sampling period, at each location and each crown height.
