Abstract

This study aims to identify the type of coffee powder aroma from the coffee beans blending using backpropagation artificial neural network (ANN). Backpropagation is a controlled training implementing a weight adjustment pattern to achieve a minimum error value between the the predicted and the actual output. Within this study, the coffee aroma testing utilized electronic tasting sensor system consisted of 4 sensors namely TGS 2611, TGS 2620, TGS 2610 and TGS 2602. The coffee aroma monitoring and data collection in this system applied LabVIEW software as a virtual instrumentation. The testing result of this ANN was able to distinguish the coffee variety of Robusta, Arabica coffee powder and the one without any coffee aroma. The backpropagation architecture was formed by 3 layers consisting of 1 input layer with 4 input nerve cells, 1 hidden layer with 8 neural cells, and 2 output layers by applying the backpropagation training algorithm. The training data was taken from 70 data samples of each circumstance of coffee with 5 testing times. The results of the training and testing showed that the established backpropagation was capable to identify and differenciate the coffee powder in accordance with the given input with different average success rate;  91.96% for Robusta coffee, 100 % for Arabica coffee, and no 84.24% for without coffee aroma.

Abstract

Temperature set of the coffee bean roasting to get the roasting temperature of arabica using thermocouple temperature cencor. Temperature monitoring is controlled by microcontroller. The suitable temperature set of roasting process determine the temperature of three conditions, they are light roast, medium roast, and dark roast. Roasting temperature set of the coffee bean have a goal to get the best quality of coffee bean.

Abstract

This study uses a backpropagation neural network to determine the evenness of the chayote chip dough. The Tcs3200 Color Sensor mounted on the stirrer alt is used as a sensor to determine the color of the chayote emping dough. A regression score of 1 indicates that the input and target data match in the test results of the artificial neural network, which has an objective error (MSE) value of 0.0096306 achieved in the 313th epoch. Changes in RGB color readings on the TCS sensor from min values ??<40 and max values>52 in mixing dough are influenced by distance and light intensity which will be converted in the form of frequency.

Abstract

Penerangan jalan akan lebih bermanfaat apabila ditempatkan pada area jalan menuju tempat-tempat ibadah seperti, masjid, mushola, gereja, pura, vihara, klenteng, dan tempat-tempat ibadah lainnya. Sebab dengan adanya penerangan jalan menuju tempat ibadah akan mempermudah akses umat beragama untuk melaksanakan ibadah di tempat ibadahnya, misalnya saja umat beragama islam yang selalu melaksanakan ibadah sholat lima waktu sehari semalam secara berjamaah di masjid atau di mushola. Terutama pada malam hari penerangan jalan sangat bermanfaat bagi masyarakat di sekitar masjid atau mushola yang terletak di kawasan yang belum terdapat PJU dari pemerintah setempat, seperti pada kasus mushalla Al-barkah Lambung Bukit kecamatan Pauh kota Padang. Mushalla Al-barkah Lambung Bukit kecamatan Pauh kota Padang merupakan salah satu tempat ibadah umat muslim  yang terletak di kawasan yang belum terdapat penerangan jalan dari pemerintah setempat, karena mushola ini dalam kondisi baru dibangun di bagian sisi sebelah jalan. oleh sebab itu, dosen prodi D3 Teknik Listrik PNP berinisiatif untuk melakukan planning PJU pada mushalla Al-barkah yang berpedoman pada SNI 7391:2008. Berdasarkan perhitungan sesuai dengan SNI 7391:2008, maka diperoleh sebanyak 47 titik lampu PJU yang akan dipasang disekitar jalan mushalla Al-Barkah. Namun untuk penerangan jalan sementara mushalla Al-Barkah, maka dipasang lampu sebanyak 6 buah di teras mushalla.
