On Generalization of Fibonacci, Lucas and Mulatu Numbers

Fibonacci numbers, Lucas numbers and Mulatu numbers are built in the same method. The three numbers differ in the first term, while the second term is entirely the same. The next terms are the sum of two successive terms. In this article, generalizations of Fibonacci, Lucas and Mulatu (GFLM) numbers are built which are generalizations of the three types of numbers. The Binet formula is then built for the GFLM numbers, and determines the golden ratio, silver ratio and Bronze ratio of the GFLM numbers. This article also presents generalizations of these three types of ratios, called Metallic ratios. In the last part we state the Metallic ratio in the form of continued fraction and nested radicals

STOCK PORTFOLIO ANALYSIS USING MARKOWITZ MODEL

A common problem that often occurs in investment is the selection of the optimal portfolio according to the wishes of investors. This thesis ueds the Markowitz Model as a basis to formed a model to choose the optimal portfolio that provided the lowest risk. Efforts to minimize risk were carried out by conducting a diversification strategy. After the selection of several companies with the criteria of capitalization value and DER (Debt Equity Ratio), a combination of stocks is formed to form a portfolio. The formed portfolio was then analyzed to determine the optimal proportion of each stock. Using the Markowitz model, which is then solved by Non Linear Programming, an optimal portfolio is obtained with the proportion of each stock minimizing risk. In general, the results of this analysis indicate that portfolios with more stocks will produce lower risks compared to portfolios with fewer stocks, thus providing optimal diversification solutions, namely portfolios with members of five stocks with optimal risk of 0.886%

Application of Exogenous Liquidity Risk Models to Analyze Single Assets

Exogenous liquidity risk measurement is a measurement of liquidity risk that affects all market participants and is not affected by the actions of any other actors. Exogenous liquidity risk measurement is usually called the Cost of Liquidity (COL). The main problem is how the level of liquidity of one currency against other currencies and the effect of liquidity risk on VaR (Value at Risk) on a single asset. This thesis examines the importance of liquidity risk on a single asset. Combining basic VaR and liquidity risk will result in more effective calculations. The model used is to add the basic VaR value with the Cost of Liquidity (COL) or also called Liquidity VaR (L-VaR). The calculation results show the different effects of liquidity for each country\u27s currency. Indonesian Rupiah (IDR) is the currency that has the highest liquidity component compared to the Japanese Yen (JPY) and the Thai Baht (THB). The lower the liquidity component of a currency, the currency is very liquid, and the Japanese Yen (JPY) is the most liquid currency compared to the Indonesian Rupiah (IDR) and the Thai Baht (THB)

ON QUASI NEWTON METHOD FOR SOLVING FUZZY NONLINEAR EQUATIONS

This paper presents Quasi Newton’s (QN) approach for solving fuzzy nonlinear equations. The method considers an approximation of the Jacobian matrix which is updated as the iteration progresses. Numerical illustrations are carried, and the results shows that the proposed method is very encouraging

The Estimated Value of Losses and Insurance Due to Citarum River Flooding

Flooding in Citarum always happens in Bandung District which causes loss of property, household damage, diseases moreover decease. The government provides aid for flood victims, but the help is not cover losses. In this circumstance, people need insurance.

Integrating Technologies in the New Normal: A Study of Blended Learning

The objective of this research is to describe how the teacher integrates technologies in blended learning and to analyze students’ perception and challenges in blended learning. The research was conducted in a private senior high school in Bandung and used a qualitative descriptive method. The data were collected through interview and questionnaire. The findings show that the teacher had already integrated technologies to run the process of teaching and learning in the new normal era as a replacement of a face to face learning due to Covid-19 pandemic. In the blended learning, the teacher integrated the variety of technologies in teaching-learning activities, namely zoom meeting and WhatsApp group chatting for the synchronous learning and she utilized google classroom, screencast o matic screen recorder, viva video editor, YouTube, and Quizizz the synchronous learning. The students perceived  blended learning positively and determined that it is it is one of the effective ways of teaching. The biggest challenge overcome by the teacher is more time needed to learn and adapt to this new situation where they must employ technology in our educational culture. For the students, the stability of internet connection also becomes major obstacle in blended learning. Apart from that, blended learning can be an option applied in the learning process in the current pandemic era
