Abstract

Intisari Kesenjangan nilai ekonomis yang cukup tinggi yang terjadi pada komoditas beberapa jenis daging konsumsi menjadi penyebab utama terjadinya kecurangan pada proses penjualannya. Secara kasat mata, beberapa jenis daging akan terlihat sama sehingga sulit untuk diidentifikasi. Dengan menggunakan pengolahan citra, data matriks dari beberapa jenis daging konsumsi akan menampilkan kecenderungan tertentu sehingga dapat dijadikan ciri identifikasi. Sampel pada penelitian ini adalah daging Kambing, daging Anjing, daging Babi, dan daging Celeng. Metode Substraksi RGB merupakan turunan dari matriks citra RGB. Dengan menggunakan metode ini, citra masing-masing jenis daging konsumsi dapat diidentifikasi. Hasil penelitian menunjukkan bahwa daging Kambing dan daging Celeng dapat diidentifikasi menggunakan substraksi GB, sedangkan daging Anjing dan daging Babi dapat diidentifikasi menggunakan substraksi GB yang dilanjutkan dengan substraksi RB.Kata kunci kecurangan penjualan daging, identifikasi daging, pengolahan citra, substraksi RGBAbstract High gap of the economic values that occurs in several types of meat commodities is a major cause of fraud of the meat sales. In plain view, several types of meat will be look similar so these were difficult to identify. By using image processing, matrix data from several types of meat will display certain trends so that it can be used as an identification feature. Samples in this study were goat meat, dog meat, pork meat, and boar meat. The RGB Substraction Method is a derivative of an RGB image matrix. Using this method, images of each type of meat can be identified. The results showed that goat meat and boar meat could be identified using GB substraction, while dog meat and pork meat could be identified using GB substraction followed by RB subtraction.Keywords meat sales fraud, meat identification,image processing, RGB substraction

Abstract

Intisari Setiap yang berputar memiliki potensi energi kinetik, tidak terkecuali putaran kubah masjid. Penelitian ini bertujuan untuk mengetahui potensi pemanfaatan kubah putar masjid sebagai penghasil energi listrik skala kecil. Generator yang diuji cobakan adalah generator magnet permanen dan generator DC yang dirangkaikan dengan turbin kubah putar. Pengujian dilakukan di dua lokasi, di Jembatan Musi 2 Palembang dan di perairan Sungsang Kabupaten Banyuasin untuk mengukur besaran tegangan dan arus output yang dihasilkan pada berbagai kecepatan angin menggunakan multimeter dan anemometer. Hasil penelitian menunjukkan bahwa tegangan yang dihasilkan oleh putaran kubah masjid menggunakan generator magnet permanen mampu mencapai 14,21 V pada kecepatan angin 3,8 m/det dibandingkan dengan generator DC yang hanya mencapai 3 V pada kecepatan angin 8 m/det. Jika ditinjau dari besaran arus, generator magnet permanen menghasilkan arus konstan sebesar 0,3 A sedangkan pada generator DC arus yang dihasilkan tidak terukur karena nilainya yang amat kecil. Penelitian ini menunjukkan bahwa kubah putar masjid dapat dijadikan sebagai turbin angin pada daerah yang memiliki kecepatan angin rendah. Kata kunci kubah masjid putar,generator magnet permanen,generatorDC, turbin angin kecepatan rendah Abstract - Every spinning has kinetic energy potential; the mosque dome is no exception. This study aims to determine the potential use of the mosque's turning dome as a producer of small-scale electrical energy. Two types of the generator were tested, which were permanent magnet generator and DC generator, which were coupled with a rotary dome turbine. The test was carried out at two locations, at Palembang Musi 2 Bridge and in the waters of Sungsang, Banyuasin Regency, to measure the amount of voltage and output current generated at various wind speeds using a multimeter and anemometer. The results showed that the voltage generated by the mosque's dome rotation using a permanent magnet generator was able to reach 14.21 V at wind speeds of 3.8 m / sec compared to DC generators, which only reached 3 V at 8 m / s wind speed. When viewed from the amount of current, permanent magnet generators produce a constant current of 0.3 A while in DC generators, the current generated is not measurable because the value is minimal. This research shows that the mosque's rotary dome can be used as a wind turbine in areas that have low wind speeds. Keywords rotary mosque domes, permanent magnet generators, generator DC, low speed wind turbines
