Pemanfaatan energy surya di daerah remote area adalah suatu hal yang makin hari makin dibutuhkan mengingat makin banyak peralatan yang dibutuhkan manusia yang menggunakan energy listrik dalam pengoperasiannya, sebaliknya tidak semua daerah yang memiliki suplai jaringan listrik, misalnya daerah laut , pesisir pantai maupun daerah-daerah terpencil lainnya. Indonesia merupakan daerah yang mendapatkan sinar matahari berlimpah sepanjang massa, namun konversi energy surya menjadi energy listrik sangat bergantung pada letak geografis, cuaca dan lingkungan tempat sel surya dioperasikan. Guna mengetahui potensi pembangkitan listrik dengan sel surya dilakukan pengujian dengan menggunakan sel surya monokristalin 100 Wp dengan waktu pengujian dari jam 07.30-16.30 WIB di halaman kampus Fakultas Teknik Cilegon pada tanggal 20 Mei 2018 – hingga 1 Juli 2018. Hasil pengamatan menunjukkan produksi listrik yang dihasilkan perhari per meter persegi luas permukaan didaerah tersebut mencapai nilai rata-rata 0,69 kWh/hari/m2. Sedangkan nilai maksimum yang mungkin dicapai adalah sebesar 1,062 kWh/hari/m2. Sehingga kebutuhan baterai terpasang untuk menampung produksi DAYA listrik yang dihasilkan perhari adalah baterai 12 V dengan kapasitas 62 Ah.

Chest-X ray (CXR) radiography can be used as a first-line triage process for non-COVID-19 patients with pneumonia. However, the similarity between features of CXR images of COVID-19 and pneumonia caused by other infections make the differential diagnosis by radiologists challenging. We hypothesized that machine learning-based classifiers can reliably distinguish the CXR images of COVID-19 patients from other forms of pneumonia. We used a dimensionality reduction method to generate a set of optimal features of CXR images to build an efficient machine learning classifier with Nvidia Jetson Nano that can distinguish COVID-19 cases from non-COVID-19 cases with high accuracy and sensitivity. By using global features of the whole CXR images, we were able to successfully implement our classifier using a relatively small dataset of CXR images. We propose that our COVID-Classifier can be used in conjunction with other tests for optimal allocation of hospital resources by rapid triage of non-COVID-19 cases.

Data dan informasi menjadi suatu hal yang tidak dapat dipisahkan dari setiap aspek kehidupan manusia. Perkembangan IT (Information Technology) yang semakin cepat juga memberikan tantangan terhadap masalah keamanan data, informasi, dan media penyimpanannya. Kriptografi dapat menjaga agar data atau informasi tetap aman, tanpa mengalami gangguan dari pihak ketiga dan kompresi dapat membuat ukuran sebuah data menjadi lebih kecil. Tujuan penelitian ini adalah untuk membandingkan antara kombinasi algoritma enkripsi-kompresi dengan algoritma kompresi-enkripsi. Penggabungan algoritma enkripsi AES 128 dan algoritma kompresi Shannon-Fano pada file txt, docx, dan pdf dengan kombinasi enkripsi-kompresi tidak cocok untuk digunakan karena membuat ukuran file bertambah dan memiliki waktu proses yang lebih lama apabila dibandingkan proses kompresi-enkripsi. Rata-rata nilai rasio kompresi untuk proses enkripsi-kompresi pada file txt, docx, dan pdf masing-masing sebesar 1.01 sedangkan rata-rata nilai rasio kompresi untuk proses kompresi-enkripsi pada file txt adalah sebesar 0.64 dan untuk file docx dan pdf masing-masing sebesar 1.00. Rata-rata nilai penghematan ruang untuk proses enkripsi-kompresi pada file txt, docx, dan pdf masing-masing adalah sebesar -1.074%, -1.040%, dan -1.025% sedangkan rata-rata penghematan ruang untuk proses kompresi-enkripsi adalah sebesar 35.896%, -0.759%, dan -0.0291%. Rata-rata waktu proses yang didapat untuk kombinasi enkripsi-kompresi pada file txt, docx, dan pdf masing-masing adalah 2.22 s, 2.179 s, dan 2.204 s sedangkan rata-rata waktu proses untuk kombinasi kompresi-enkripsi 2.05 s, 2.114 s, dan 2.122 s.

Presensi adalah suatu pendataan kehadiran, bagian dari pelaporan aktivitas suatu institusi, atau komponen institusi itu sendiri yang berisi data-data kehadiran yang disusun dan diatur sedemikian rupa sehingga mudah untuk dicari dan dipergunakan apabila sewaktu-waktu diperlukan oleh pihak yang berkepentingan. Aplikasi komputer yang dikembangkan pada sistem presensi adalah aplikasi komputer yang dapat mengenali wajah seseorang hanya dengan menggunakan webcam. Sistem pengenalan wajah ini menggunakan algoritma eigenface, dengan menggunakan citra yang dihasilkan melalui webcam dan menggunakan informasi mentah dari pixel citra yang kemudian direpresentasikan dalam metoda Principal Component Analysis (PCA). Hasil dari pengujian sistem presensi menggunakan ekspresi wajah, aksesoris wajah dan variasi jarak, didapat sensivisitas 100%, spesifisitas 55.55 %, dan akurasi 69.33 %.

Health is a valuable treasure in survival and can be used as a parameter of quality assurance of human life. Some people even tend to ignore of health, so don’t care about the disease that will them attack and finally to death. Noted the main disease that causes death in the world is cancer. Cancer has many types, but the greatest death in each year is caused by breast cancer. Indonesia found more than 80% of cases in advanced stage, it is estimated that the incidence get 12 people from 10000 women. These numbers will to grow when there is no such treatment as prevention or early diagnosis. Growing of breast cancer patients inversely proportional to the percentage of complaints patients to doctors diagnosis in USG (Ultrasonography) breast cancer 20%. The problem is ultrasound imaging which is distorted by speckle noise. The solution is to help easier for doctors to diagnose the presence and form of breast cancer using USG. Speckle noise on USG is able to good reduce using SRAD (Speckle Reducing Anisotropic Diffusion). The filtering results are then well segmented using Fuzzy C-Means Clustering with an accuracy 91.43% of 35 samples USG image breast cancer.

The energy use that is in excess of practicum students’ needs and the disturbed comfort that the practicum students experience when conducting practicums in the Electrical eengineering vocational education (EEVE) laboratory. The main objective in this study was to figure out how to predict and streamline the use of electrical energy in the EEVE laboratory. The model used to achieve this research’s goal was called the adaptive neuro-fuzzy inference system (ANFIS) model, which was coupled with principal component analysis (PCA) feature selection. The use of PCA in data grouping performance aims to improve the performance of the ANFIS model when predicting energy needs in accordance with the standards set by the campus while still taking students’ confidence in conducting practicum activities during campus operating hours into consideration. After some experiments and tests, very good results were obtained in the training: R=1 in training; minimum RMSE=0.011900; epoch of 100 per iteration; and R=0.37522. In conclusion, the ANFIS model coupled with PCA feature selection was excellent at predicting energy needs in the laboratory while the comfort of the students during practicums in the room remained within consideration.

Development of microprocessor technology provides new ideas for creating smart devices, one of which is in the field of smart home. Smart home is a concept of a home integrated with a smart system and supported by technology that enables all work to be more effective and efficient. Mirror is a household device that is beneficial to humans. In this paper, a research on smart mirrors is explained. A smart mirror is a mirror integrated with an intelligent system so that it can display multimedia data originating from the internet using Raspberry as a computing tool, PIR sensor as a tool to control monitors, and DC fans as a tool to control temperature system. In this paper, the mirror was able to display information about time, weather, academic calendar, lab work schedules, prayer schedules, and academic news. A PIR sensor has a good accuracy when the device is placed at 180 cm above the ground and the distance between mirror and humans when mirroring is 70 cm. A DC fan was utilized to stabilize the system temperature in a range of 40 to 50 oC.
