Abstract

Dalam dekade terakhir ini, perkembangan saham syariah meningkat secara signifikan. Hal iniditunjukkan dengan makin banyaknya saham-saham yang berbasis syariah. Selain itu, munculnyaindeks yang menjadi benchmark saham syariah di bursa efek menambah menariknya kegiataninvestasi bagi para investor. Seperi harga saham pada umumnya, harga saham syariah juga seringberubah-ubah (berfluktuasi), sehingga investasi pada saham syariah pun dihadapkan pada risikoinvestasi. Berdasarkan karakteristik tingkat risiko, kinerja investasi pada suatu saham syariah perludilakukan analisis. Oleh karena itu, dalam paper ini dilakukan analisis kinerja beberapa sahamsyariah dengan pendekatan rata-rata dan volatilitas tak konstan. Rata-rata tak konstan dimodelkandengan menggunakan model-model Autoregressive Moving Average (ARMA), sedangkan Volatilitastak konstan dianalisis menggunakan model-model Generalized Autoregressive ConditionalHeteroscedastic (GARCH). Sedangkan untuk menganalisis kinerja investasi pada saham syariahdilakukan dengan menggunakan model Sharpe’s measure. Sebagai ilustrasi numeric, metodetersebut digunakan untuk menganalisis beberapa saham syariah di Indonesia. Hasil yangdiharapkan adalah dapat diketahuinya kinerja investasi saham syariah untuk beberapa periodemendatang.

Abstract

Since the early 1990s, a slew of chaotic-based communication systems have been proposed, all of which take advantage of chaotic waveform properties. The inspiration stems from the substantial benefits that this form of nonlinear signal offers. Many communication schemes and applications have been specifically designed for chaos-based communication systems to achieve this goal, with energy, data rate, and synchronization awareness being taken into account in most designs. However, non-coherent chaos-based systems have recently received a lot of attention in order to take advantage of the benefits of chaotic signals and non-coherent detection while avoiding the use of chaotic synchronization, which has poor performance in the presence of additive noise. This paper provides a thorough examination of all wireless radio frequency chaos-based communication systems. It begins by describing the difficulties of chaos implementations and synchronization processes, then moves on to a thorough literature review and study of chaos-based coherent techniques and their applications.

Abstract

Conjugate Gradient (CG) method is a technique used in solving nonlinear unconstrained optimization problems. In this paper, we analysed the performance of two modifications and compared the results with the classical conjugate gradient methods of. These proposed methods possesse global convergence properties for general functions using exact line search. Numerical experiments show that the two modifications are more efficient for the test problems compared to classical CG coefficients.

Abstract

Fractional calculus is related to derivatives and integrals with the order is not an integer. Fractional Black-Scholes partial differential equation to determine the price of European-type call options is an application of fractional calculus in the economic and financial fields. Laplace decomposition method is one of the reliable and effective numerical methods for solving fractional differential equations. Thus, this paper aims to apply the Laplace decomposition method for solving the fractional Black-Scholes equation, where the fractional derivative used is the Caputo sense. Two numerical illustrations are presented in this paper. The results show that the Laplace decomposition method is an efficient, easy and very useful method for finding solutions of fractional Black-Scholes partial differential equations and boundary conditions for European option pricing problems.

Abstract

Extreme distribution is the distribution of a random variable that focuses on determining the probability of small values in the tail areaof the distribution. This distribution is widely used in various fields, one of which is reinsurance. An outbreak catastrophe is non-natural disaster that can pose an extreme risk of economic loss to a country that is exposed to it. To anticipate this risk, the government of a country can insure it to a reinsurance company which is then linkedto bonds in the capital market so that new securities are issued, namely outbreakcatastrophe bonds. In pricing, knowledge of the extreme distribution of economic losses due to outbreak catastrophe is indispensable. Therefore, this study aims to determine the extreme distribution model of economic losses due to outbreak catastrophe whose models will be determined by the approaches and methods of Extreme Value Theory and Peaks Over Threshold, respectively. The threshold value parameter of the model will be estimated by Kurtosis Method, while the other parameters will be estimated with Maximum Likelihood Estimation Method based on Newton-Raphson Iteration. The result of the research obtained is the resulting model of extreme value distribution of economic losses due to outbreak catastrophe that can be used by reinsurance companies as a tool in determining the value of risk in the outbreak catastrophe bonds.

Abstract

Bonds are types of securities in the form of a debt acknowledgment letter for loan money from the public in a certain form, but with a minimum tenor of three years and promise of interest rewards in which the amount and payment have been determined in advance. Looking at the current global problems regarding degradation of environmental equality and climate change, bonds were developed where the proceeds of issuance were exclusively applied to finance environmentally friendly projects, is green bonds. However, the issuance of green bonds in Indonesia is slight. This research aims to find out the comparison of individual performance of green bonds and conventional bonds traded on the Indonesia Stock Exchange. The method used to measure performance is Sharpe Ratio. The result indicates that performance of green bond worse than conventional bond. This research can be used as a consideration for investor in making investment based on performance.

Abstract

As with any other business that has a risk of any incident in the future, the insurance business also needs protection against the risks that may arise in the company so that the company does not lose. Therefore, the need for anticipation in organizing any claims submitted by the insurance company to Reinsurance Company so that insurance company may assign any or all of the risks to reinsurance companies. In the method of reinsurance excess-of-loss there is a certain retention limits that allow reinsurance companies bear no claims incurred on insurance companies. The results of this study showed the average occurrence of claims and the risks that may be encountered by Reinsurance Company during the period of insurance. The magnitude of the risk assumed by the reinsurer relies on the model claims aggregation formed from individual claim size distribution models and distribution models the number of claims incurred in the period of insurance. Besides the magnitude of risk was also determined from the retention limit of insurance and reinsurance method used.
