Material jalan yang paling dibutuhkan adalah aspal. Aspal Buton merupakan bahan galian yang sampai saat ini masih dilakukan penambangan dan pemanfaatannya untuk masyarakat lokal di Buton maupun di daerah lainnya. Salahsatu penambangan aspal serta industri pengolahan aspal alam berada di PasarWajo, Kabupaten Buton, Sulawesi Tenggara. Aspal Buton memiliki karakteristik yang berbeda-beda. Perbedaan sifat ini disebabkan perbedaan batuan asalnya dan penetrasi bitumennya. Tujuan penelitian ini untuk mengetahui karakteristik sifat fisik mineral aspal buton pada wilayah Kabungka di lokasi tambang pit B, C, dan Winto di PT.Wijaya Karya Bitumen. Metode yang digunakan dengan pengujian kadar bitumen dengan alat sokhlet, uji kadar air dengan alat denstrak, dan uji berat jenis. Berdasarkan hasil penelitian di dapatkan hasil pada Pit B, didapatkan kadar air  sebesar 5 %, dan kadar  bitumen 28,63 %, pada Pit C didapatkan kadar air sebesar 14.2 %, dan kadar bitumen 16,87 %, dan pada Pit Winto didapatkan kadar air sebesar 0,8 % dan kadar bitumen 23,49 %. Hasil analisis berat jenis pada Pit B didapatkan berat jenis sebesar 1,51 g/m3. pada Pit C didapatkan berat jenis sebesar 1,71 g/m3, dan pada Pit Winto didapatkan berat jenis sebesar 1.62 g/m3. Berdasarkan hasil analisis kadar air dan kadar bitumen Asbuton wilayah kabungka Pit B, C, Pit Winto, dapat diketahui bahwa karakteristik serta  kadar air dan kadar bitumen Asbuton tiap tambang berbeda-beda, dimana pada Pit B, sifat elastis (lunak) tidak muda pecah, warna coklat kehitaman-hitam, dengan berat jenis rata-rata 1,50 %. Pada Pit C sifat padat (keras) muda pecah, warna hitam, abu-abu kehitaman, dengan berat jenis rata-rata 1,71 %, dan struktur amorf (kompak).

Currently, HER2 breast cancer is detected using variety of medical test which are most expensive. Therefore, the aim of this study was to develop a computational model named convoHER2 for detecting HER2 breast cancer with image data using convolution neural network (CNN). Hematoxylin and eosin (H&E) and immunohistochemical (IHC) stained images were used as raw data from the Bayesian information criterion (BIC) benchmark dataset. This dataset consists of 4873 images of H&E and IHC. Among all images of the dataset, 3896 and 977 images were applied to train and test the convoHER2 model, respectively. All images of this dataset are resized due to high resolution of the image for forming better detection performance of convoHER2 model. Moreover, the dataset is classified into four different labels (0+, 1+, 2+, 3+) for identifying the grade of detected HER2 breast cancer. The convoHER2 model is able to detect HER2 cancer and its grade with accuracy 85% and 88% using H&E images and IHC images, respectively. The outcomes of this study determined that the HER2 cancer detecting rates of the convoHER2 model are much enough to provide better diagnosis to the patient for recovering their HER2 breast cancer in future.","PeriodicalId":36368,"journal":{"name":"AIUB Journal of Science and Engineering","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135757362","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Kualitas dan kuantitas udara di tambang bawah tanah kencana dikaji dengan memperhitungkan nilai Thermal Work Limit, debit udara yang masuk dan keluar serta kehilangan energi (head loss) pada secondary fan. Berdasarkan hasil pengolahan data diperoleh, ada 7 front yang berada pada zona aklimatisasi yang berada pada rentang nilai 140 – 219 dan 2 front yang berada pada zona buffer yang berada pada rentang nilai 116 – 139, 2 front berada pada zona buffer dikarenakan win speed yang sampai ke face rendah. Hasil pengolahan data debit udara secara kondisi aktual dan simulasi diperoleh udara di jalur exhaust lebih besar dibandingkan dengan udara di jalur fresh air, hal ini dikarenakan adanya kebocoran pada vent door yang membatasi antara jalur fresh air dan exhaust.
