Abstract
Pencemaran udara merupakan salah satu masalah yang ditimbulkan oleh pembakaran bahan bakar pada proses industri. Untuk mencegah pencemaran udara, dilakukan kegiatan pengamatan cerobong asap oleh Badan Lingkungan Hidup. Pengamat Badan Lingkungan Hidup akan mengukur tingkat kepekatan asap dari cerobong industri untuk mengetahui apakah asap yang dihasilkan oleh cerobong industri melebihi batas aman yang sudah ditetapkan atau tidak. Badan lingkungan hidup menggunakan skala Ringelmann Smoke Chart untuk menentukan tingkat kepekatan asap. Selama ini pengukuran tingkat kepekatan asap dilakukan pengamat dengan melihat citra asap melalui teropong dan kemudian membandingkannya dengan Ringelmann Smoke Chart ecara manual. Pengukuran dengan cara tersebut memiliki keterbatasan. Pengamatan tidak dapat dilakukan ketika penglihatan pengamat tidak dalam kondisi yang bagus. Selain itu data pengamatan masih dicatat dengan tulisan tangan pada kertas laporan pengamatan, sehingga tidak praktis dalam melihat perkembangan kepekatan asap dari cerobong. Untuk mengatasi permasalahan tersebut, dibuatlah aplikasi pengukuran tingkat kepekatan asap dan pencatatan data pengamatan yang berjalan pada smartphone berbasis Windows Phone. Aplikasi ini mengukur tingkat kepekatan asap dengan menghitung euclidean distance histogram RGB (Red, Green, Blue) dari citra asap dengan masing-masing tingkatan pada Ringelmann Smoke Chart. Tingkat kepekatan asap diambil berdasarkan tingkatan pada Ringelmann Smoke Chart yang memiliki euclidean distance terendah terhadap citra asap. Selain pengukuran tingkat kepekatan asap, aplikasi ini juga memiliki beberapa fitur lain, yaitu penyimpanan data pengamatan pada server, menampilkan riwayat pengukuran, dan benchmark nilai kepekatan asap.

Air pollution is one of the many problems caused by fuel combustion in industrial processes. To prevent air pollution, chimney observation activities conducted by the environmental agency. People from BLH (Badan Lingkungan Hidup) will measure the density of smoke from The industrial chimney to determine whether the smoke produced by The chimney exceeds safe limits that have been set or not. People from Badan Lingkungan Hidup is using the Ringelmann Smoke Chart scale to determine the opacity of the smoke produced by the chimney. Until now, the smoke density measurements performed by the observers is to see the image of the smoke through binoculars and then compare it with the Ringelmann Smoke Chart manually. Measurements in this way has its limitations, the observations can not be performed when the visual capability of the observer is not in a good condition, and the observational data is still written by hand on a paper reporting the observations, so that observers has difficulty in seeing the development of the smoke from the chimney. To overcome these problems, an application of smoke opacity measurement and recording of observational data ,that runs on Windows Phone, is made. This application measures the opacity of smoke by calculating the euclidean distance histogram of RGB (Red, Green, Blue) from the image of smoke with each level on the Ringelmann Smoke Chart. Smoke opacity levels chosen based on the Ringelmann Smoke Chart that has the lowest euclidean distance with the image of the smoke. In addition to the smoke opacity measurement, this application also has some other features such as, data storage of the observation data on the server, displays a history of measurement, and benchmarking the value of smoke opacity.
