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

Indonesian corn production data in 2018 reached 30 million tons, and generally, corncobs have not been utilized. This research is processing corncobs into bioethanol as an effort to exploit the potential of abundant corncobs. The process is carried out in 3 stages, namely hydrolysis with acid (H2SO4 0.5N), fermentation with bread yeast (fermipan), and distillation at 1000C. The study conducted in a three-neck flask equipped with heating, stirring, and turning cooling. The research material used was 40 grams of corncobs powder, H2SO4 0.5N as much as 300 ml, yeast 3 grams, and urea 0.1 gram. The hydrolysis process was carried out using 40gr of corncobs powder, and 0.5N H2SO4 with a volume of 300 ml. Stirring is carried out at 140 rpm rotation with varying time and temperature. Next, the fermentation process is carried out by adding as much as 3 grams of yeast and 0.1 grams of urea. The fermentation process takes 3 days. The distillation process is carried out at a temperature of 1000C with a long time for 2-3 hours. Based on our research, it knows that the time and temperature of hydrolysis affect the ethanol content produced. Optimal addition of yeast at 0.4271% ethanol content is weighing 3 grams. The optimal fermentation time for ethanol content 0.66447% is at the time of fermentation of 3 days.

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.

Abstract

Mengingat pentingnya kebutuhan air bersih pada suatu gedung maka sistem plambing penyediaan air bersih merupakan bagian yang tidak dapat terpisahkan agar distribusi air bersih ke seluruh bagian yang memerlukan dapat terpenuhi dengan debit dan tekanan yang sesuai. Dengan perkembangan fungsi dan kebutuhan maka terjadi pengembangan gedung tanpa dilakukan analisis kesesuaian sistem penyaluran air bersih sehingga akan mengakibatkan sistem penyediaan air bersih menjadi kurang efisien dan efektif dan berdampak pada biaya operasional yang tinggi. Sistem plambing penyediaan air bersih pada gedung meliputi sistem penyediaan air bersih, instalasi air bersih, analisa perhitungan kebutuhan air bersih yang meliputi mengetahui perkiraan jumlah penghuni, mengetahui pemakaian air bersih dalam sehari, dan mengetahui berapa pemakaian air bersih berdasarkan jenis dan jumlah alat plambing, analisa perhitungan perencanaan pipa air bersih yang meliputi mengetahui dimensi pipa air bersih dari ground water tank ke roof tank, dengan menggunakan sumber air tanah maupun PDAM.
