Abstract

Penyebab terbesar terjadinya polusi udara adalah asap kendaraan bermotor yang mengandung senyawa atau partikulat berbahaya. Kandungan tersebut dapat masuk dalam tubuh melaui proses respirasi dan membahayakan organ paru. Oleh karena itu perlu dilakukan penelitian untuk mengukur partikel ultrafine yang terdapat pada asap kendaraan bermotor dan mengetahui bagaimana pengaruh asap kendaraan bermotor terhadap organ paru. Pada asap kendaraan bermotor mengandung partikulat matter berupa partikel ultrafine yang dapat masuk melalui saluran pernafasan dan sampai pada organ paru yang merupakan satu-satunya organ yang berhubungan dengan udara luar. Keberadaan senyawa dan partikulat di dalam tubuh akan membahayakan organ paru yang berperan penting untuk proses respirasi. Pada penelitian ini dilakukan pemberian asap yang berasal dari sepeda motor terhadap mencit sebanyak 3 kali setiap hari selama 10 hari dengan variasi pemberian asap sebanyak 6 perlakuan (0, 30, 60, 90, 120, dan 150 detik). Hasil penelitian ini didapatkan persentase kerusakan alveoli paru mencit mencapi 70% dan total partikel ultrafine mencapai 2,4x1010. Semakin lama pemberian asap, semakin besar total partikel ultrafine, semakin meningkat persentase kerusakan alveoli paru mencit.

Abstract

Asap kendaraan bermotor menduduki posisi pertama sebagai sumber pencemaran udara. Asap kendaraan bermotor mengandung partikel ultrafine yang berbahaya bagi tubuh khususnya organ hati. Oleh sebab itu dilakukan penelitian yang bertujuan untuk menganalisis dampak yang ditimbulkan oleh partikel ultrafine yang berasal dari kendaraan bermotor terhadap organ hati. Pada penelitian dilakukan pengasapan terhadap hewan coba menggunakan 2 sepeda motor dengan 6 perlakuan. Pengasapan dilakukan selama 3 kali sehari selama 10 hari berturut-turut. Berdasarkan penelitian yang telah dilakukan didapatkan semakin banyak partikel ultrafine yang diberikan maka semakin tinggi persentase kerusakan organ hati mencit. Selain itu terbukti jika salah satu kandungan asap kendaraan bermotor yaitu partikel ultrafine dapat merusak organ hati. Partikel ultrafine dapat masuk dalam tubuh melalui proses respirasi. Partikel ultrafine dapat menembus sel epitel paru dan mausk ke dalam peredaran darah yang akhirnya terbawa oleh darah menuju hati. Partikel ultrafine yang masuk dalam tubuh akan menyebabkan stress oksidatif dan peradangan yang pada akhirnya menimbulkan efek kerusakan. Pada penelitian ini persentase kerusakan sel hati akibat pengasapan mencapai 40% pada kendaraan bermotor 1 dan 44% pada kendaraan bermotor 2. Kata kunci : Asap kedaraan bermotor, Partikel ultrafine, Organ Hati.

Abstract

The increase of motor vehicle population in Indonesia causes the increase of pollution substances in ambient air, such as Particulate Matter with the diameter <2.5 µm or fine particle (PM2.5). There are many methods developed to reduce the PM2.5 concentrations emitted by motor vehicles, such as a biomass particulate filter. This study was aimed to develop biomass PM2.5 filters made of sawdust and wood glue with three different composition ratio: F1, F2, and F3. The PM2.5 concentrations before and after passing through the filters were measured using a Digital Dust Monitor (Kanomax, Model 3443) for 200 seconds of the sampling times. The filter efficiency was obtained from the reduction ratio of the PM2.5 concentrations before and after being filtered. Based on the surface morphology test using an electron microscope SEM, the diameters of the filter pores were 9.11 – 19.7 µm with the different densities. The efficiency was 33% to 52%, depending on the ratio of the sawdust and wood glue. A higher filter density (2.72 x 10-3 g/cm3) generated a higher filter efficiency (52%).

Abstract

Carbon dioxide (CO2) has been known well as a contributor gas for the global warming. Regarding the impact, the measurement of the CO2concentration in the air is very important for the assessment. This paper presents the design of a CO2 instrument built by using the components that are available in the market.  The instrument contains a CO2 sensor, an interfacing system, and a computer. The test showed that the instrument worked well. It could be used to measure a CO2 concentration on line and in real time.

Abstract

A practical monitoring system implementing an asynchronous interrupt driven sampling technique has been developed in this research. This system is intended to acquire power-line single-phase voltage and current signals as well as their related information such as RMS values and harmonic contents. The system uses a voltage transformer and a current transducer to acquire the signals of the voltage and current. A microcontroller is used in the system to perform acquisition processes, calculation, and wireless data transmission. The design activities include the development of hardware of the system and software in the microcontroller as well as monitoring software with Bluetooth technology that will run on portable devices. As part of the research, a new sampling technique was developed to provide constant and precise timings during the acquisition processes. In this technique, some peripherals related to the acquisition process were driven asynchronously using interrupt mechanisms. Some experimentation has been carried out, and the result showed that the system implementing this technique could successfully manage the timings for the synchronous acquisition sequences. Furthermore, the use of the Bluetooth interfaces in the system allowed practical monitoring process to be performed using portable devices.

Abstract

Background: Lung cancer is the second leading cause of death in the world due to delays in diagnosis. Non-invasive Volatile Organic Compound (VOC) method to diagnose and monitor the progressivity of lung cancer. Interleukin-17 (IL-17) has an important role in the progression and treatment of lung cancer. Objective evaluation of chemotherapy using Response Evaluation Criteria in Solid Tumors (RECIST 1.1). This study aims to determine the relationship between VOC, IL-17, and lung cancer chemotherapy response based on RECIST at Saiful Anwar General Hospital, East Java.Methods: In a prospective cohort study, 47 lung cancer patients received first-line chemotherapy pre and post-three series of chemotherapy. Exhaled breath was collected with Tedlar Bags and then analyzed with µβreath for VOC. IL-17 in blood serum is determined by an enzyme-linked immunosorbent assay (ELISA). The data were analyzed using the Wilcoxon, Mann-Whitney, and Spearman tests.Results: There were significant in VOC Components (p 0.05) Formaldehyde (CH2O), Toluene (C7H8), Acetone (C3H6O), Hexane (C6H14), Methane (CH4), RECIST non-target lesions, and new lesions pre and post-three series of chemotherapy but not found in IL-17. Acetone (C3H6O) pre and Methane (CH4), IL-17 post-three series of chemotherapy based on RECIST Overall Response (OR) found significant. The analysis showed a positive correlation between Formaldehyde (CH2O) pre and Methane (CH4), IL-17 post-three series of chemotherapy based on RECIST OR, but a negative correlation between Acetone (C3H6O) pre-chemotherapy. Conclusions: There was a significant decrease in formaldehyde, toluene, hexane, methane and an increase in acetone in lung cancer patients pre and post-three series of chemotherapy. There was a significant relationship between formaldehyde, acetone pre-chemotherapy, and methane, IL-17 post-three series of chemotherapy based on the RECIST overall response

Abstract

The adverse effects of air pollution on human health, climate change, and ecosystems have made air pollution a major problem in the last four years. Ammonia is a pollutant that has an impact on human health. This study aims to develop a monitoring system for NH3 concentrations using radio communication. The radio module used in data communication is SX1278. The sensor used in this system is MICS-6814, which is integrated with Arduino Nano. The sensor used has been tested and can be used in emission detection. Monitoring results data is displayed on the LCD and serial monitor. Data communication performance for the monitoring process was tested at various distances. This system can reach a measurement distance of 80 meters, with the best distance used for monitoring being less than 50 meters. This system was tested to be able to monitor a different level building. The result shows that the system's performance is the RSSI at a distance of 0 meters is -28 dBm. At the same time, the farthest distance of 80 meters is -101 dBm. The data transmission has a delay time of 1,300 ms and an accuracy of 91%. The ambient NH3 concentration in the area of Malang is found in the range of 0.001 ppm.
