Abstrak :
Skin cancer is a malignant growth on the skin caused by many factors. The most common skin cancers are Basal Cell Cancer (BCC) and Squamous Cell Cancer (SCC). This research uses a discriminant analysis to classify some tissues of skin cancer based on criterion number of independent variables. An independent variable is variation of excitation light sources (LED lamp), filters, and sensors to measure Autofluorescence Intensity (IAF) of visible light to near infrared (VIS/NIR) ratio of paraffin embedded tissue biopsy from BCC, SCC, and Lipoma. From the result of discriminant analysis, it is known that the discriminant function is determined by 4 (four) independent variables i.e., Blue LED-Red Filter, Blue LED-Yellow Filter, UV LED-Blue Filter, and UV LED-Yellow Filter. The accuracy of discriminant in classifying the analysis of three skin cancer tissues is 100 %.

Skin cancer as the most common cancer diagnosis tend to be increasing. This condition is a particularly significant issue in developed countries. This study aimed to describe the clinical features, histopathological features, complications, and early surgical treatment outcomes of skin cancer in Can Tho Oncology Hospital from 2014 to 2015. This descriptive prospective study involved all patients with non-melanoma skin cancer that were examined and treated at Can Tho Oncology Hospital from July 2014 to March 2015. There were 78 cases selected. Skin cancer was found to be more common among older patients. The prevalence of basal cell carcinoma was found higher than squamous cell carcinoma with percentage worth 76.9% and 23.1% respectively. Worth 73.1% of all the patients in the study underwent surgery with wide resection and reconstruction. In this study, most patients were the elderly. The basal cell carcinoma was the most common. The main treatment was surgery with wide resection and reconstruction. The complication was rare 1.3% with skin flap necrosis.

Kanker kulit di Indonesia menempati urutan ketiga teratas dengan persentase sebesar 15,1% dari total 13 kanker yang paling umum diderita di Indonesia. Kanker kulit disebabkan oleh radiasi sinar ultraviolet yang merusak DNA di dalam sel kulit manusia. Penggunaan tabir surya setiap hari dapat meminimalkan probabilitas terjadinya kanker kulit. Efisiensi tabir surya dinyatakan dalam nilai SPF. Penggunaan bahan pelindung matahari dari bahan alam dipercaya lebih aman dan tidak banyak memiliki efek samping. Salah satu sumber hutan Indonesia yang berpotensi mengandung SPF alami adalah lemak tengkawang. kehadiran senyawa fenolik pada lignin memiliki kemampuan pertahanan terhadap sinar UV, sehingga lignin disebut sebagai bahan penahan sinar UV alami. Penelitian ini mengevaluasi penambahan lignin yang mengandung fenolik untuk meningkatkan kandungan SPF pada lemak tengkawang. Pada penelitian ini lemak tengkawang mengalami tahap degumming, netralisasi dan pemucatan. Hasil penelitian menunjukkan bahwa nilai SPF pada lemak tengkawang bernilai 7,052 dan penambahan l0% (b/b) lignin berhasil meningkat nilai tersebut menjadi 53, 549. ......Skin cancer in Indonesia ranks the top three with a percentage of 15,1% of 13 most common cancers suffered in Indonesia. Skin cancer is caused by ultraviolet radiation with ability to damages human DNA skin cell. The use of sunscreen every day can decrease the probability of skin cancer. The efficiency of sunscreen is expressed in SPF values. The use of sun protection agent from natural materials is believed to be more safe and less side effects. One of Indonesia's forest resources that potentialy contain natural sun protection factor is illipe butter. The presence of phenolic compounds in lignin has the ability to defend against UV rays, so lignin can be called as natural UV retaining agent. This study will evaluate the addition of lignin which contain phenolic that has the ability to increase the SPF value in illipe butter. In this research, the treatment of illipe butter will consist of degumming, neutralization and bleaching. The result showed that the SPF value of illipe butter is 7,052 and the addition of 10% (w/w) lignin succeded in increasing SPF value into 53,549.

Penelitian ini menyajikan ekstraksi fitur citra dermatoskopik untuk diagnosis kanker kulit melanoma berdasarkan asymmetry, border irregularity, color variation, dan diameter (ABCD). Fitur ABCD adalah informasi yang penting berdasarkan analisis morfologi lesi citra dermatoskopik. Fitur tersebut digunakan dalam perhitungan Total Dermatoscopic Value (TDV) untuk diagnosis kanker kulit melanoma. Fitur asymmetry terdiri dari informasi asimetri dan indeks perpanjangan luka. Fitur border irregularity terdiri dari informasi indeks compactness, dimensi fraktal, edge abruptness, dan transisi pigmentasi dari lesi. Warna fitur homogenitas terdiri dari informasi homogenitas warna dan korelasi antara fotometri dan geometri lesi. Ekstraksi diameter adalah diameter lesi. Ada tiga diagnosa yang digunakan pada penelitian ini yaitu melanoma, diduga melanoma, dan benign skin lesion. Percobaan ini menggunakan 30 sampel dari lesi citra dermatoskopik kanker kulit melanoma yang mencurigakan. Berdasarkan percobaan, akurasi dari sistem ini adalah 85% dan terdapat empat diagnosa palsu dari 30 sampel.
Abstract
This research present asymmetry, border irregularity, color variation, and diameter (ABCD) feature extraction of image dermatoscopic for melanoma skin cancer diagnosis. ABCD feature is the important information based on morphology analysis of image dermatoscopic lesion. ABCD feature is used to calculate Total Dermatoscopic Value (TDV) for melanoma skin cancer diagnosis. Asymmetry feature consist information of asymmetry and lengthening index of the lesion. Border irregularity feature consist information of compactness index, fractal dimension, edge abruptness, and pigmentation transition from the lesion. Color homogeneity feature consist information of color homogeneity and the correlation between photometry and geometry of the lesion. Diameter extraction is diameter of the lesion. There are three diagnosis that is used on this research i.e. melanoma, suspicious, and benign skin lesion.
