Abstract

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.

Abstract

Survival analysis is a statistical method used to evaluate the time an event occurs, particularly in censored data. In this study, the Nelson-Aalen method was applied to analyze the survival probability of patients with kidney failure based on medical data from Hasanuddin University Hospital. This method was used to calculate the cumulative hazard and survival function of patients. The analysis results showed that the longer a patient was treated, the greater the chance of recovery. The Nelson-Aalen method was considered more efficient in handling small samples compared to other non-parametric methods. This study provides important insights for healthcare practitioners in planning patient care and improving their quality of life.

Abstract

The coronavirus first appeared in Wuhan, China, in early December 2019. This virus is also known as Coronavirus disease 2019 (COVID-19). Based on the increasing number of COVID-19 cases and the high number of deaths, further research is deemed necessary. In this case, an effective treatment is needed to accelerate patient recovery. Two commonly used drugs are Remdesivir and Favipiravir. This study used the Kaplan-Meier method to evaluate the recovery time of COVID-19 patients based on two types of treatment: Remdesivir and Favipiravir. Survival analysis was conducted to compare the effectiveness of the two treatments in prolonging patient recovery time. The results showed a difference in effectiveness between the two types of treatment in terms of survival probability.

Abstract

Sukuk Ritel merupakan instrumen investasi syariah yang banyak diminati masyarakat karena menawarkan imbal hasil tetap serta kepastian hukum syariah. Harga Sukuk Ritel di pasar sekunder dapat mengalami perubahan, yaitu mencapai kondisi harga premium ketika harga pasar lebih tinggi dari nilai nominal/harga par (face value) dan sebaliknya ketika mencapai harga diskon. Fenomena ini menarik bagi para investor karena dapat menghasilkan capital gain dan capital loss. Penelitian ini bertujuan membangun model matematika penentuan harga premium dan harga diskon pada Sukuk Ritel menggunakan pendekatan nilai ekonomi dari waktu yang sesuai dengan prinsip keuangan syariah. Metode penelitian menggunakan studi literatur, studi simulasi, studi kasus, konstruksi formula matematika, analisis terhadap kepatuhan syariah dan analisis model matematika yang dikembangkan. Hasil simulasi menunjukkan bahwa harga premium dan harga diskon terbentuk berturut-turut ketika tingkat kupon sukuk lebih tinggi dan lebih rendah dari tingkat harga pada pasar perdana. Penelitian ini memberikan kontribusi terhadap ketersediaan model matematika untuk ketiga kemungkinan harga Sukuk Ritel (premium, par dan diskon) berbasis syariah dan dapat dijadikan rujukan bagi investor serta pengambil kebijakan di bidang keuangan syariah.

Abstract

Salah satu masalah dalam model risiko kumpulan untuk periode yang diperluas adalah menentukan model peluang kebangkrutan perusahaan asuransi. Dalam model tersebut, proses klaim diasumsikan mengikuti proses Poisson Majemuk, sedangkan distribusi besar klaim dimisalkan eksponensial. Tujuan penelitian ini adalah menentukan peluang kebangkrutan pada kasus proses klaim mengikuti proses Poisson Majemuk dan distribusi besar klaim adalah eksponensial. Model peluang kebangkrutan diperoleh dengan dua cara yaitu menggunakan pendekatan koefisien penyesuaian dan persamaan integro-diferensial. Hasil penelitian memperlihatkan bahwa kedua cara tersebut memberikan model peluang kebangkrutan yang sama.

Abstract

This study aims to model and analyze the ruin probability of an insurance company using an integro-differential equation under the assumption that claim sizes follow a Gamma distribution. The research method employed is a literature study, conducted by reviewing relevant books and scientific articles. The modeling process is carried out using an integro-differential equation and simplifying it into the form of a homogeneous linear differential equation. Numerical computations are performed using Python programming, and the results are presented in tables and graphs to facilitate analysis. The model is developed in four cases based on variations in the parameters of the Gamma distribution. The results show that the ruin probability decreases as the initial capital and premium loading increase, and increases as the expected value of claims rises. Therefore, an increase in the insurance company’s surplus will reduce the risk of ruin.

Abstract

Since 2016, the Government of the Republic of Indonesia has implemented the Rice Farming Insurance (AUTP) program as mandated by law. In the context of Central Java, with its large Muslim population and successful implementation of sharia economics, it is necessary to develop an AUTP model based on sharia principles. This research aims to create an AUTP model by applying sharia principles (Sharia AUTP or AUTPS) based on a rainfall index and to determine the amount of contribution and compensation within the AUTPS framework. The research methodology employs literature study and model development through stages of planning, analysis, pre-design, actuarial calculation, and final design. The research data comprises rainfall and rice production data from Brebes Regency for the years 2018–2022. The novelty of this research lies in the application of sharia principles and the use of a rainfall index to replace crop failure-based insurance. Consequently, the actuarial calculation for implementing contributions and compensation is based on the rainfall index. The contribution amount is calculated using the Black-Scholes Cash-or-Nothing Put Option equation, while compensation is calculated using the historical burn analysis method. The research results in a proposed rainfall index-based AUTPS model, where the contribution amount is determined based on rainfall percentiles, and compensation payments are categorized as maximum compensation, partial compensation, or no compensation. The mechanism for managing contributions (premiums) follows sharia principles and yields two types of AUTPS: AUTPS-R (without a savings element) and AUTPS-RI (with a savings element). The recommendation from this research is the need to pilot the developed concept in collaboration with a sharia insurance company before it is adopted as a policy by the Regional Government of Central Java Province.

Abstract

Kronogram merupakan bentuk penyandian yang banyak digunakan dalam budaya Barat dengan mengusung penggunaan angka Romawi. Dalam budaya Timur, terdapat penyandian yang menyerupai kronogram dan disebut sengkala, sengkalan atau sangkalan dengan cara merangkaikan kata-kata yang memiliki watak bilangan atau nilai numerik 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 serta menggunakan prinsip angkanam vamato gatih. Tujuan penelitian ini adalah menjelaskan eksistensi dua buah sengkala yang terkait dengan Kabupaten Banyumas. Penelitian dilakukan dengan penelusuran pustaka. Hasil penelitian ini adalah ditemukan adanya dua buah sengkala yang terkait dengan Kabupaten Banyumas yang disusun menggunakan kalender Masehi, sehingga kedua sengkala lamba tersebut berupa suryasengkala lamba. Selanjutnya, penyusunan kedua suryasengkala lamba tersebut mengikuti cara penyusunan sengkala dalam Kitab Negarakertagama sehingga rangkaian kata yang menyusun masing-masing suryasengkala lamba menghasilkan makna tertentu.
