Abstract

Heart disease is still ranked first in the WHO most dangerous and deadly disease in the world. This is also influenced by the individual's reluctance to check his heart condition routinely. So we need an application that is able to help overcome this. SIBioS application is a mobile-based application that functions to analyze heart rate. SIBioS is useful to help with the initial diagnosis of the presence or absence of cardiovascular disorders in individuals. The method applied for data analysis in SIBioS applications is case-based reasoning. Each heart rate data obtained will be calculated the degree of closeness of the distance to the heart rate contained in the knowledge base owned. So that the individual's heart rate can be informed. The test results show SIBioS is able to provide information about the status of the heart condition tester in accordance with the real condition of the tester at the time of measurement. In addition to using the right data analysis method, the results of heart rate data analysis are also influenced by the smartwatch device which is used as a media for tapping heart rate data, gender, age, daily physical activity, individual professional status, and supporting factors when measuring the resting heart rate. Case-based reasoning analysis methods can be applied to heart rate analysis to determine the condition of a person's heart under normal conditions or the presence of cardiovascular disorders. The physical activity recommendations given by the system are determined based on the individual's heart condition.

Abstract

Ikan merupakan salah satu sumber protein hewani dan sangat diminati masyarakat Indonesia, dari survey bahan makanan yang diminati, bandeng peringkat keempat dibanding bahan makanan yang lain. Khususnya ikan bandeng, ikan ini menjadi satu dari enam ikan yang banyak dikonsumsi masyarakat selain tongkol, kembung, teri, mujair dan lele, maka ketelitian masyarakat ketika membeli ikan bandeng menjadi perhatian serius dalam memilih ikan bandeng segar. Deteksi kesegaran dengan menyentuh tubuh ikan dapat mengakibatkan kerusakan tanpa disengaja, maka deteksi kesegaran ikan harus dilakukan tanpa menyentuh ikan bandeng dengan memanfaatkan citra kondisi mata. Dalam riset ini, kami melakukan eksperimen implementasi klasifikasi kesegaran ikan bandeng sangat segar dan tidak segar berdasarkan mata menggunakan transfer learning dari empat CNN, yaitu Xception, MobileNet V1, Resnet50, dan VGG16. Dari hasil eksperimen klasifikasi dua kelas kesegaran ikan bandeng menggunakan 154 citra menunjukkan bahwa VGG16 mencapai kinerja terbaik dibanding arsitektur lainnya dimana akurasi klasifikasi mencapai 0.97. Dengan akurasi lebih tinggi dibanding arsitektur lainnya maka VGG16 relatif lebih tepat digunakan untuk klasifikasi dua kelas kesegaran ikan bandeng. AbstractFish, one source of animal protein, is an exciting food for Indonesia's people. From a survey of food-ingredients demanded, milkfish are ranked fourth compared to other food-ingredients. Especially for milkfish, this fish is one of the six fish consumed by Indonesia's people besides tuna, bloating, anchovies, tilapia, and catfish, so the exactitude of the people when buying is a severe concern in choosing fresh milkfish. Detection of freshness by touching the fish's body may cause unexpected destruction, so detecting the fish's freshness should be conducted without touching using the eye image. In this research, we conducted an experimental implementation of freshness milkfish classification (vastly fresh and not fresh) based on the eyes using transfer learning from several CNNs, such as Xception, MobileNet V1, Resnet50, and VGG16. The experimental results of the classification of two milkfish freshness classes using 154 images show that VGG16 achieves the best performance compared to other architectures, where the classification accuracy achieves 0.97. With higher accuracy than other architectures, VGG16 is relatively more appropriate for classifying two classes of milkfish freshness.

Abstract

Rumah pintar yang sering disebut sebagai Smarthome atau e-Home yaitu suatu rumah yang memiliki sistem otomatis yang sangat canggih untuk mengontrol peralatan rumah. Pada umumnya, instalasi pada rumah masih menggunakan saklar untuk mengoperasikan peralatan elektronik. Contohnya menggunakan saklar untuk mematikan dan menghidupkan lampu. Dengan sistem tersebut kita masih harus menekan saklar jika ingin mematikan dan menyalakan lampu. Menjadi hal biasa bagi orang yang sehat untuk melakukannya. Akan tetapi, bagaimana dengan orang sakit yang berada di kursi roda/tempat tidur atau orang disabilitas atau orang lanjut usia yang tidak dapat mencapai saklar ketika ingin menghidupkan/mematikan perangkat rumah dan mereka tidak dapat melakukannya. Hal ini tentunya menjadi kebutuhan bagi mereka untuk membangun sebuah smart home berbasis IoT (Internet of Things) yang dapat membantu mereka mengontrol perangkat rumah dengan mudah dan dapat dikontrol dari mana saja, sehingga munculah teknologi berupa rumah pintar atau Smart Home. Selain menggunakan tombol On/Off pada interface berbasis web maupun mobile, smart home dapat dikontrol dengan menggunakan perintah suara. Perintah suara sangat cocok digunakan untuk sistem home automation. Pengolahan suara digital dikontrol dengan aplikasi untuk mengenali adanya perintah suara yang dideteksi, yang sering disebut dengan Voice Recognition. Voice Recognition dapat dikatakan sebagai suatu proses di mana mesin atau program menerima dan menafsirkan dikte serta memahami dan menjalankan perintah yang diucapkan. Berdasarkan hasil prototype yang telah dibuat dan diuji, dapat disimpulkan bahwa dalam kehidupan sehari-hari Smart Home sangat dibutuhkan, karena sangat efektif dan efisien dalam segi waktu dan kegiatan untuk mengontrol beberapa instalasi yang ada dirumah dengan perintah suara. Dengan adanya prototype smart home ini diharapkan bisa membantu kegiatan sehari-hari saat dirumah.

Abstract

The growth of organizations in the field of literacy is very good for the development of children's interest in reading and insight at an early age, especially in the city of Surabaya. Taman Bacaan Masyarakat (TBM) is an organization that has an important role to support and facilitate the community in seeking knowledge in the field of literacy in particular. The addition of TBM in Balai RW, Kelurahan, Kecamatan, and in the corners of community crowds is a tangible manifestation of the role of the Surabaya City Library and Archives Service as the authority that intersects directly in the field of literacy to facilitate the reach of the public in finding quality sources of information. However, several technical factors influence the selection of TBM addition locations that are still very objective. And the limited budget for the establishment of TBM also affects the number of TBM founding locations
