Analisis Lanjut Metode Beda Hingga Eksplisit Untuk Menentukan Harga Opsi
Authors: Sastro Wahyudi 
Published: May 2021

Abstract. Explicit finite difference method is used to approximate a partial differential equation that is applied to determine the option pricing. The results of this study note that the calculation of option pricing using explicit finite difference method is negative when partition N ≥ 25 with a value of -2.21. Thus, the results of the calculation of option pricing are not convergent and away from the results of analyzing the option pricirng (Black-Scholes) solution. This is because one of the three probabilities Bj = 1- σ2j2Δt is negative, namely (-0.12) when j ≥ 12 with S ≥ 16.25 (in units). So this explicit finite difference method cannot be used to determine the option pricing.
Keywords: Option Pricing, Explicit Finite Difference Method

Abstrak. Metode beda hingga eksplisit digunakan untuk mengaproksimasi suatu persamaan diferensial pasial yang aplikasikan untuk menentukan harga opsi. Hasil penelitian ini diketahui bahwa perhitungan harga opsi dengan menggunakan metode beda hingga eksplisit bernilai negatif pada saat partisi N ≥ 25 dengan nilai -2,21. Dengan demikian, hasil perhitungan harga opsi tidak konvergen dan menjauhi hasil solusi analitik perhitungan harga opsi (Black-Scholes). Hal ini disebabkan karena salah satu ketiga probabilitas Bj = 1- σ2j2Δt yaitu bernilai negatif yaitu (-0.12) saat j ≥ 12 dengan S ≥ 16.25 (dalam satuan). Sehingga metode beda hingga eksplisit ini tidak dapat digunakan untuk menentukan harga opsi.

Abstract. One of the methods used to overcome overdispersion in poisson regression model is a bivariate negative binomial regression model also known as BNBR Model. Leprosy is a dangerous infectious disease, because it can cause paralysis. Leprosy is divided into 2 types, namely is a leprosy Pausibasilier(PB) type and leprosy Multibasilier (MB) type. Where PB type leprosy is a dry leprosy and MB type leprosy is a wet leprosy. Analysis of the data used to model the number of PB leprosy and MB leprosy cases and find out what factor influence it in East Java, the writer uses the BNBR models. Parameter estimation of the BNBR model uses to Maximum likelihood estimation (MLE) methods with Newton-Raphson iteration as well as testing the hypothesis using MLRT methods. After regression analysis, the results are obtained that of the 10 predictor variables tested, both in PB leprosy and MB leprosy, there are 3 predictor variables that are not significant in the model, namely are: variable percentage of poor population, variable ratio of population who did not graduated SMA, and variable ratio of health facilities.

Published: May 2021

El cavernoma cerebral es una lesión vascular del sistema nervioso central, la segunda más frecuente (10-15%) de los cuatro tipos de malformaciones cerebrales, entre las que se encuentran la malformación arteriovenosa, telangiectasia capilar y la anomalía venosa del desarrollo; asociándose a esta última en aproximadamente 9% de los casos. Su prevalencia estimada es solo del 0,4% en la población general. Reporte de caso de mujer de 23 años de edad, que acudió al servicio de urgencias por cefalea intensa, acompañada de vértigos intensos y de vómitos en varias oportunidades; con alteración del estado de conciencia. Se realizó tomografía axial computarizada simple de cráneo, debido a la edad de la paciente y a la localización de la lesión se procedió a realizar una resonancia magnética nuclear que demostró imágenes sugestivas de un cavernoma cerebeloso complicado con hemorragia y un angioma venoso contiguo. Se realizó tratamiento conservador y se solicitó la repetición de la RMN al mes de la primera indicación con el objetivo de valorar la evolución de la lesión y de la hemorragia. Los cavernomas frecuentemente no son detectados con una angiografía por presentar un flujo lento y por la tendencia a trombosis, siendo la herramienta diagnóstica más sensible la resonancia magnética nuclear. Se sugiere la conducta expectante frente a lesiones múltiples, a aquellas que son inaccesibles quirúrgicamente o que cursan sin complicaciones.

This paper is aimed to provide the best advice related to the importance of risk culture in facing Covid-
19 pandemic. As we know, until now, July 2020, the number of victims who were infected by Covid-
19 is increasing every day. The latest information on July 20, 2020, In Indonesia, there were more tha n
88,000 people were positive covid-19 and more than 4000 people died. This number continues to increase every day. It even happened in one day, the number of positive victims increased to more than 1000 cases. This indirectly indicates a failure in managing risk and a lack of awareness of all parties toward the importance of risk culture. In this paper, we will learn how to develop and nurture risk culture in organization by integrating risk management, transformational leader, and change management. This paper was written based on the study literatures. The result of the paper explains that risk culture is one of the most importance things which should be done in facing this Covid-19 pandemic and facing others risk. It is also provided guidelines related to what should be done or not when facing risks. For organizations, the given advice is that all parties in that organization (risk management, transformational leader, and change management) must collaborate in developing and nurturing risk culture. Moreover, specially to face Covid-19 Pandemic, the given advice is that all of the parties (community, government, and medical personnel) must understand the importance of risk culture and cooperate to face the pandemic.
