Abstract

In this COVID-19 pandemic period, the majority of people do their activities indoors. A high number of activities could increase indoor pollution. Some of the pollutants easily found in the house include particulate matter with sizes of <2.5 micrometers (PM2.5) and carbon dioxide (CO2). Both types of these pollutants can enter the body and interfere with health. This study aims to measure the concentration of pollutants in the house and estimate daily exposure and risk level. This study measured the concentration of PM2.5 and CO2 in two houses, house A located in a housing complex in Bandung Regency, and house B, located on the side of Garut City main road. The measuring instruments are placed in 3 points: kitchen, family room, and outdoors. The concentration of PM2.5 in the neighborhood of house A is higher than the concentration of PM2.5 in the neighborhood of house B due to the high construction activity. Large ventilation in house A causes the PM2.5 concentration to follow the outdoor concentration pattern. As for house B, the concentration of PM2.5 is much influenced by the source from the kitchen. The activities much influence the concentration of CO2 for both houses in each room. The relative risk of PM2.5 for cardiovascular and cardiopulmonary disease in each house differed depending on the duration of exposure. Calculation of the relative risk of PM2.5 was conducted on normal people in house A and house B, and the chef in house B. The highest relative risk was obtained by the chef in house B, followed by normal people in house B and house A. The level of relative risk for the chef at house B is 30% for cardiovascular disease and 34% for cardiopulmonary disease. ABSTRAK Di masa pandemi COVID-19, mayoritas masyarakat melakukan kegiatannya di dalam rumah. Aktivitas yang tinggi dapat menyebabkan polutan dalam rumah meningkat. Beberapa jenis polutan dapat dengan mudah ditemukan di dalam rumah di antaranya adalah partikulat berukuran <2,5 mikrometer (PM2,5) dan karbon dioksida (CO2). Kedua jenis polutan tersebut dapat masuk ke dalam tubuh dan mengganggu kesehatan. Penelitian ini bertujuan untuk mengukur konsentrasi polutan dalam rumah dan mengestimasi paparan harian dan tingkat risikonya. Penelitian ini mengukur konsentrasi PM2,5 dan CO2 di dua tipe rumah, yaitu rumah A yang terletak di perumahan Kota Bandung, dan rumah B, terletak di samping jalan utama kota Garut. Alat ukur diletakan pada tiga ruangan, yaitu dapur, ruang keluarga, dan luar ruang. Lingkungan rumah A memiliki konsentrasi polutan PM2,5 yang lebih tinggi dari rumah B karena tingginya aktivitas pembangunan permukiman dan jalur kereta cepat. Ventilasi yang besar pada rumah A menyebabkan konsentrasi PM2,5 cenderung mengikuti pola luar ruang. Sementara itu untuk rumah B, tingginya aktivitas di dapur mempengaruhi konsentrasi polutan PM2,5 dalam rumah. Konsentrasi CO2 untuk kedua rumah pun berbeda untuk tiap ruang. Rata-rata sumber CO2 pada tiap ruang di masing-masing dipengaruhi oleh aktivitas dari tiap ruangan tersebut. Tingkat risiko PM2,5 terhadap penyakit kardiovaskular dan kardiopulmoner pada masing-masing rumah berbeda tergantung dari durasi paparannya. Perhitungan tingkat risiko PM2,5 dilakukan pada orang normal di rumah A dan B, dan juru masak di rumah B. Tingkat risiko tertinggi dihasilkan oleh juru masak di rumah B, diikuti dengan orang normal di rumah B dan A. Tingkat risiko pada juru masak di rumah B sebesar 30% untuk penyakit kardiovaskular dan 34% untuk penyakit kardiopulmoner.

Abstract

The limitations of expensive main monitoring stations can be addressed by using low-cost sensor-based measuring stations. A low-cost sensor-based air quality monitoring system has been implemented in Telkom University, BRIN Pasteur, and BRIN Taman Sari areas to measure PM2.5 and CO2 concentration in Bandung vertically and horizontally. Vertically, the CO2 concentration at the highest measuring station is indirectly affected by local activities. However, PM2.5 concentration is still influenced by local actions. Horizontally, using the independent T-test and ANOVA, PM2.5 concentrations tended to be homogeneous regarding the significance values in the four periods, namely 0.916, 0.03, 0.727, and 0.047. Meanwhile, the concentration of CO2 at each station tends to be heterogeneous along significance values of 0.646, 0.03, 0.02, and 0.01. The vertical and horizontal analysis shows that CO2 concentrations tend to be heterogeneous due to differences in altitude and spatial characteristics of the measurement sites. Meanwhile, PM2.5 tends to be more homogeneous by having the same pattern at different heights and spatial locations. The long-distance potential sources of PM2.5 are estimated to come from the Indian Ocean and Cirebon region because they have the highest PSCF and CWT values, 0.5-0.7 and 55-65 µg/m3.

Abstract

One of the problems that occur in Indonesia is air pollution caused by the high intensity of citizen activity, especially most of which still use fossil-fueled motor vehicles to carry out their activities. The fossil fuel that is not burned perfectly can cause gas and particle pollution to form which can cause its amount to increase in the air and affect the environment. Therefore, measurement of motor vehicle emission tests based on low-cost sensors is conducted with CO, CO2, NO2, PM2.5, temperature, and humidity as its parameters. The usage of flow rate is addressed to the flow of the emission gas, which will be measured from an exhaust of a motor vehicle into the testing chamber and forwarded into the air for disposal. The flow rate used in this test ranges from 12-15 lpm. For that reason, the author performed the test for 10 minutes and got the average results of the measured parameters. The results are 1200 ppm for CO, 140000 ppm for CO2, and 80 °C for temperature (the show results are the average of the test results). The results shown are due to the small range of the low-cost sensor resulting in a huge difference.

Abstract

Masih banyak orang yang menganggaptinggi badan bukanlah sesuatu hal yang penting.Pengukuran tinggi badan secara rutin pada anak jugasangat dianjurkan untuk memantau pertumbuhan dandapat mencegah terjadinya stunting. Di Indonesia, stuntingmerupakan masalah yang serius. Berdasarkan data SurveiStatus Gizi Balita Indonesia tahun 2019, stunting diIndonesia mencapai 27,7%. Angka tersebut masih tinggidibandingkan ambang batas WHO yaitu 20%. Penelitianyang akan dilakukan adalah pembuatan aplikasi yangdapat melakukan pengukuran tinggi badan pada citradigital dan memprediksi status gizi anak yang diukur. Citraakan diolah menggunakan ArUco marker danmenggunakan algoritma Decision Tree untuk memprediksistatus gizi.
