ABSTRAK Latar Belakang: Asimetri pada wajah dan lengkung gigi merupakan fenomena yang dapat ditemui hampir pada seluruh individu sehingga saat ini asimetri dengan batas-batas tertentu masih dianggap seimbang secara klinis dan dinilai normal. Asimetri mandibula merupakan asimetri yang paling sering terjadi dan mudah terlihat dikarenakan mandibula adalah bagian wajah yang paling mudah bergerak dibandingkan bagian wajah lainnya. Asimetri mandibula ditemukan paling tinggi dan dapat memengaruhi perawatan. Untuk mendiagnosis asimetri mandibula dapat dilakukan dengan pemeriksaan klinis ekstra oral yang meliputi pemeriksaan smile symmetry. Tujuan: Mengetahui frekuensi dan distribusi terjadinya asimetri mandibula pada mahasiswa angkatan tahun 2016 FKG UI dan mengetahui berapa persen mahasiswa yang mengalami asimetri mandibula. Metode: Metode yang digunakan pada penelitian ini adalah analisis gambaran klinis yang dilakukan untuk melihat adanya asimetri atau disporposi pada wajah tampak frontal khususnya pada mandibula. Analisis dilakukan dengan cara fotografi frontal dalam kondisi standar dan kondisi gigi tersenyum. Kesimpulan: Pada mahasiswa FKG UI angkatan 2016 terdapat 37 subjek (32,2%) dengan asimteri mandibula dan terdapat 57 subjek (49,6%) yang memiliki senyum tidak simetris.
ABSTRACT Background: Facial asymmetry is a phenomenon found in almost every individual, thus asymmetry within certain boundaries is accepted as clinically balanced and normal. Mandibular asymmetry is the most common asymmetry that can occur and is easily seen because the mandibula is the part of the face that is most mobile compared to the rest of the face. Mandibular asymmetry are the most common asymmetry that can affect treatment for asymmetry. Mandibular asymmetry can be diagnosed by extra oral clinical examination which includes smile symmetry. Objective: Knowing the frequency and distribution of mandibular asymmetry in In Faculty Of Dentistry batch 2016 students and knowing what percentage of students experience mandibular asymmetry. Method: The method used in this research is clinical image analysis which is used to see whether asymmetry or facial disproportion on the frontal face image, especially on the mandibula, is present. The analysis is done via frontal photography in a standard setting. Conclusion : In Faculty Of Dentistry batch 2016, there were 42 subjects with mandibular asymmetry and 58 subjects with asymmetry smile.

[Model Black-Scholes merupakan model pertama penentuan harga opsi. Terdapat asumsi-asumsi yang harus dipenuhi pada model Black-Scholes, salah satunya volatilitas yang konstan. Karena asumsi tersebut, maka nilai implied volatility berdasarkan model Black-Scholes akan sama untuk setiap harga opsi. Implied volatilty dipengaruhi oleh harga strike dan waktu jatuh tempo. Namun, pada skripsi ini, implied volatility dibatasi pada pengaruh harga strike saja dan hubungan antara implied volatility dengan harga strike diinterpretasikan dalam kurva smile. Bentuk kurva smile berbeda-beda tergantung pada data observasi nilai opsi di pasar dan bentuknya seperti senyum (smile), skew, atau smirk. Dengan mempelajari kurva smile, seorang investor dapat mempertimbangkan risiko berinvestasi opsi. Pada skripsi ini dibahas bagaimana cara menentukan implied volatility Heston yang diinterpretasikan dalam kurva smile. Untuk dapat menentukan implied volatility Heston, diperlukan harga opsi Heston yang disubstitusi ke model harga opsi Black-Scholes. Untuk memperoleh harga opsi Heston, dilakukan penurunan harga opsi saham Heston berdasarkan model pergerakan harga saham Heston. Kemudian, dengan menghitung beberapa nilai implied volatility Heston yang diperoleh dengan menggunakan harga strike yang berbeda, dapat dibentuk kurva smile Heston. Hasil analisis kurva smile dari implied volatility Heston menggunakan data Anglo American Shares dengan selang harga strike dan tingkat bunga bebas risiko yang berbeda serta waktu jatuh tempo yang tetap adalah sebuah kurva smile yang berbentuk smirk. ......Black-Scholes model is the first option pricing model. There are some assumptions that need to be satisfied in Black-Scholes model, one of them is the constant volatility. Because of that assumption, implied volatility from Black-Scholes model will be same for all option price. Implied volatility depends on strike price and time to maturity. However, in this skripsi, implied volatility is bounded by strike price only and the relation between implied volatility and strike price is interpreted in smile curve. The shapes of smile curve is vary through observed option price effect and its shape looks like smile, skew, or smirk. With studying smile curve, an investor can consider the risk of investing an option. This skripsi will study how to determine Heston implied volatility which is interpreted in smile curve. Heston option price which is substituted to Black-Schole model is needed to determine Heston implied volatility. For that purpose, deriving Heston option pricing model based on Heston stock price model is needed to be done. Then, by calculating some of implied volatilities that have different strike price, smile curve can be made. The analysis result of Anglo American Shares data with different in Strike Price interval and risk-free rates but same in maturity time (1 year) is a smirk shaped smile curve.;Black-Scholes model is the first option pricing model.

Latar belakang: Estetika wajah merupakan sesuatu yang dianggap penting oleh masyarakat karena selain meningkatkan rasa kepercayaan diri seseorang, estetika wajah juga dapat mempengaruhi kualitas hidup seseorang. Estetika wajah terdiri dari Estetika Makro (Facial), Estetika Mikro (Dental), dan Estetika mini (Dentofacial). Estetika mini atau senyum terdiri dari beberapa indikator penentu, salah satunya adalah incisor display. Estetika sendiri memiliki subjektivitas yang tinggi dan bergantung pada persepsi. Sehingga, penting untuk mengetahui persepsi senyum menurut ortodontis dan orang awam untuk menentukan rencana perawatan. Tujuan: Mengetahui perbedaan persepsi estetika senyum pada berbagai level incisor display di dalam masing-masing kelompok orang awam dan ortodontis. Metode: Penelitian ini dilakukan di Jakarta menggunakan metode cross-sectional. Kuesioner ini disebar kepada 100 orang awam dan 100 ortodontis menggunakan kuesioner daring. Hasil: Terdapat perbedaan bermakna persepsi estetika senyum pada level incisor display 0 mm dengan 4 mm, serta perbedaan sebagian bermakna pada level 1mm, 2mm, 3mm, 4mm menurut orang awam. Menurut ortodontis terdapat perbedaan bermakna pada level 0mm dengan 1mm, 2mm, 3mm, dan 4mm. Terdapat juga perbedaan sebagian bermakna pada level 1mm, 2mm, 3mm, 4mm. Kesimpulan: Incisor display pada level tertentu memengaruhi persepsi estetik orang awam dan juga ortodontis ......Background: Facial aesthetics are something that is considered important by the society. They consist of Macro Aesthetics (Facial), Micro Aesthetics (Dental), and Mini Aesthetics (Dentofacial). The mini or smile aesthetics consist of several defining indicators, one of which is the incisor display. Aesthetic itself has high subjectivity and depends on perception. Thus, it is important to know the perception of smile according to the orthodontist and the laypeople to determine a treatment plan. Objective: To determine the differences in the perception of smile aesthetics at various levels of incisor display within each group of laypeople and orthodontists. Methods: This study was conducted in Jakarta using a cross-sectional method. The questionnaire was distributed to 100 laypeople and 100 orthodontists, via online questionnaire. Results: There are significant differences in the aesthetic perception of smiles at the 0mm and 4mm incisor display levels, and partial differences are significant at 1mm, 2mm, 3mm, 4mm according to laypeople. According to orthodontists, there are significant differences in 0mm with 1mm, 2mm, 3mm, and 4mm and partial differences are significant at 1mm, 2mm, 3mm, 4mm. Conclusion: Incisor display influences the aesthetic perception of laypeople and orthodontists on most levels.

This paper presents a lip and smile detection method based-on the normalized RGB chromaticity diagram. The method employs the popular Viola-Jones detection method to detect the face. To avoid the false positive, the eye detector is introduced in the detection stage. Only the face candidates with the detected eyes are considered as the face. Once the face is detected, the lip region is localized using the simple geometric rule. Further, the the red color thresholding based-on the normalized RGB chromaticity diagram is proposed to extract the lip. The projection technique is employed for detecting the smile state. From the experiment results, the proposed method achieves the lip detection rate of 97% and the smile detection rate of 94%.

Paper ini menyajikan medote pendeteksi bibir dan senyum berdasarkan diagram tingkat kromatis RGB ternormalisasi. Metode ini menggunakan metode Viola-Jones yang populer untuk mendeteksi wajah. Untuk menghindari kesalahan positif, detektor mata diperkenalkan pada tahapan deteksi. Hanya kandidat wajah dengan mata yang telah terdeteksi yang dianggap sebagai wajah. Setelah wajah dideteksi, bagian bibir ditempatkan dengan menggunakan aturan geometris sederhana. Selanjutnya, batasan warna merah berdasarkan pada diagram kromatisitas RGB ternormalisasi digunakan untuk mengekstrak bibir. Teknik proyeksi digunakan untuk mendeteksi keadaan tersenyum. Dari hasil percobaan, metode yang diusulkan mencapai 97% untuk tingkat deteksi bibir dan 94% untuk tingkat deteksi senyum.
