Penelitian ini membahas konstruksi distribusi Marshall-Olkin-Kumaraswamy-Eksponensial (MOKw-E), yang merupakan kombinasi distribusi Marshall-Olkin (MO) dan Kumarawasmy-Eksponensial (Kw-E). Distribusi ini dikenal sebagai model fleksibel yang dapat diaplikasikan untuk data dengan berbagai bentuk distribusi. Estimasi parameter dilakukan menggunakan Maximum Likelihood Estimation (MLE) dengan bantuan dua metode numerik, yaitu metode Nelder-Mead dan metode Gradien Konjugat Fletcher Reeves. Kedua metode ini banyak digunakan dalam penyelesaian permasalahan optimasi karena memiliki tingkat efisiensi yang tinggi dengan komputasi yang sederhana tetapi memberikan hasil yang akurat. Kedua metode ini akan dibandingkan dengan melihat nilai Mean Squared Error (MSE) yang merupakan suatu metrik untuk melihat seberapa cocok model dengan data yang digunakan. Terakhir, model yang dikembangkan diaplikasikan pada data severitas klaim asuransi pengangguran untuk menunjukkan kemampuan model dalam memodelkan data severitas klaim. Model tersebut akan dibandingkan dengan model yang dibangun dari distribusi Kw-E dengan melihat nilai Akaike Information Criteria (AIC) dan Bayessian information criteria (BIC) untuk menunjukan bahwa model yang dikembangkan lebih baik dibandingkan model asalnya.

This research discusses the construction of the Marshall-Olkin-Kumaraswamy-Exponential (MOKw-E) distribution, which is a combination of the Marshall-Olkin (MO) and Kumaraswamy-Exponential (Kw-E) distributions. This distribution is known as a flexible model applicable to data with various distribution shapes. Parameter estimation is performed using Maximum Likelihood Estimation (MLE) with the assistance of two numerical methods the Nelder-Mead method and the Conjugate Gradient Fletcher Reeves method. Both methods are widely used in solving optimization problems due to their high efficiency with simple computations yet accurate results. These methods will be compared by examining the Mean Squared Error (MSE) values, which is a metric to assess how well the model fits the data. Finally, the developed model is applied to unemployment insurance claim severity data to demonstrate the model's capability in representing severity claim data. The model will be compared with a model built from the Kw-E distribution by evaluating the Akaike Information Criteria (AIC) and Bayesian Information Criteria (BIC) values to show that the developed model is superior to the original model.

"Distribusi Lindley diperkenalkan oleh Lindley 1958 dalam konteks inferensi Bayes. Baru-baru ini, perluasan dari distribusi Lindley diusulkan oleh Ghitany 2013 dan disebut distribusi yang dihasilkan disebut distribusi power Lindley. Skripsi ini akan memperkenalkan perluasan dari distribusi power Lindley menggunakan metode Marshall-Olkin dan akan menghasilkan distribusi power Lindley Marshall-Olkin PLMO. Distribusi PLMO dapat lebih fleksibel dalam merepresentasikan data dengan berbagai bentuk. Sifat fleksibilitas ini disebabkan oleh penambahan parameter ke distribusi power Lindley. Beberapa sifat PLMO akan dijelaskan dalam skripsi ini, seperti probability density function pdf, cumulative distribution function cdf, fungsi survival, fungsi hazard, kuantil, dan momen ke-r. Estimasi parameter PLMO dilakukan dengan menggunakan metode maksimum likelihood. Distribusi PLMO diterapkan pada data dan akan dibandingkan dengan distribusi Lindley, power Lindley, Lindley Marshall-Olkin LMO , gamma, dan Weibull. Perbandingan model akan menggunakan nilai log likelihood, AIC, dan BIC.

Lindley distribution was introduced by Lindley 1958 in the context of Bayes inference. Recently, a new generalization of the Lindley distribution was proposed by Ghitany et al. 2013 , called power Lindley distribution. This paper will introduce an extension of the power Lindley distribution using the Marshall Olkin method, resulting in Marshall Olkin Extended power Lindley MOEPL distribution. The MOEPL distribution offers a flexibility in representing data with various shapes. This flexibility is due to the addition of a tilt parameter to the power Lindley distribution.

Some properties of the MOEPL were explored, such as probability density function pdf, cumulative distribution function cdd, hazard rate, survival function, and quantiles. Estimation of the MOEPL parameters was conducted using maximum likelihood method. The proposed distribution was applied to data. The results were given which illustrate the MOEPL distribution and were compared to Lindley, power Lindley, Marshall Olkin Extended Lindley MOEL, gamma, and Weibull. Models comparison using the log likelihood, AIC, and BIC showed that MOEPL fit the data better than the other distributions. "

"Fungsi hazard dapat dikategorikan menjadi dua, yaitu monoton (naik atau turun) dan non monoton (bathtub shape dan upside down bathtub shape). Untuk memodelkan datadengan fungsi hazard monoton, naik atau turun, dan non monoton bathtub shape umumnya digunakan distribusi Gamma atau Weibull. Pada skripsi ini, akan diperkenalkan sebuah distribusi yang dapat memodelkan data dengan fungsi hazard berbentuk upside down bathtub shape. Distribusi ini diturunkan dari distribusi Lindley dengan melakukan transformasi yang disebut distribusi generalized inverse Lindley. Distribusi ini lebih fleksibel dalam memodelkan data dengan fungsi hazard non-monoton upside down bathtub. Hal ini dikarenakan parameter shape pada distribusi tersebut menyebabkan fungsi hazard memiliki banyak variasi bentuk namun tetap mempertahankan bentuk upside down bathtub. Beberapa karakteristik dari distribusi seperti fungsi kepadatan peluang, fungsi distribusi, fungsi survival, fungsi hazard,dan momen ke-r akan dicari. Untuk mengestimasi parameter distribusinya akan digunakan metode maximum likelihood. Di akhir skripsi ini, akan dibangun data untuk mengestimasi parameter dari distribusi yang bersangkutan

Hazard rate are categorized by their shape, either its monotone (decreasing or increasing) or non-monotone (upside down bathtub shaped and bathtub shaped). Modelling data from monotone hazard rate, either decreasing or increasing, and bathtub shaped hazard rate are possible with common distribution such as Gamma distribution or Weibull distribution. For data which has upside down bathtub shaped hazard rate is usually done by using inverse transformation of exponential distribution such as inverse Gamma, inverse Weibull, and inverse Lindley. In this paper, a distribution that can model a data with upside down bathtub shaped hazard rate is introduced. The distribution is derived from Lindley distribution with transformation and is called generalized inverse Lindley distribution. The distribution is more flexible because shape parameter which make wide variety of shape without changing its hazard rate from upside down bathtub shaped. Somestatistic properties of the distribution such as density function, cumulative function, survival function, hazard function, and moment will be discussed. For estimatingparameter of the distribution, maximum likelihood method will be used. In the end, simulation data will be generated to see the estimation of the distributions parameter."

"Data lifetime biasanya digunakan peneliti untuk mengetahui tingkat survival atau tingkat kegagalan suatu objek. Distribusi Weibull merupakan distribusi probabilitas yang sering digunakan untuk memodelkan data lifetime. Namun, distribusi Weibull hanya dapat memodelkan data lifetime dengan tingkat kegagalan atau hazard rate yang monoton. Sehingga dibutuhkan distribusi baru yang dapat memodelkan data lifetime dengan karakteristik tingkat kegagalan atau hazard rate yang beragam. Distribusi inverse Weibull adalah distribusi hasil transformasi inverse dari distribusi Weibull. Distribusi inverse Weibull merupakan distribusi yang dapat memodelkan data lifetime dengan hazard rate monoton (turun) maupun  non-monoton (upside-down bathtub shaped). Namun, untuk membuat kepadatan fleksibel dengan berbagai macam bentuk diperlukan generalisasi dari distribusi ini dengan menambahkan suatu parameter shape. Distribusi generalized inverse Weibull merupakan generalisasi dari distribusi inverse Weibull yaitu yang dibentuk dengan memangkatkan fungsi distribusi inverse Weibull dengan suatu parameter baru. Distribusi generalized inverse Weibull memiliki 2 parameter shape dan 1 parameter scale sehingga distribusi ini dapat menggambarkan shape dari fungsi hazard yang lebih beragam. Pada  skripsi ini, akan dibahas mengenai pembentukan distribusi inverse Weibull dan pembentukan distribusi generalized inverse Weibull, serta fungsi kepadatan probabilitas, fungsi distribusi, fungsi survival, fungsi hazard, dan karakteristik-karakteristik dari kedua distribusi tersebut. Penaksiran parameter dari distribusi generalized inverse Weibull menggunakan metode maksimum likelihood.

Lifetime data is usually used by researchers to determine the level of survival or failure rate of an object. Weibull distribution is a probability distribution that is often used to model the lifetime data. However, the Weibull distribution is only used to model the lifetime data with monotone failure rate or monotone hazard rate. So that, a new distribution is needed to model the lifetime data with varying characteristics of failure rates or hazard rates. Inverse Weibull distribution is a distribution that is formed from the inverse transformation of the Weibull distribution. Inverse Weibull distribution is a continued distribution which can model lifetime data with a monotone hazard rate (constant, increase, and decrease) or non-monotone hazard rate (upside-down bathtub shaped). However, to make a density flexible with wide variety of shapes the generalizations from this distribution are needed by adding a shape parameter. Generalized inverse Weibull distribution is derived from generalization of inverse Weibull distribution that is formed by raising the inverse Weibull distribution function with a new parameter. Generalized inverse Weibull distribution has two shape parameters and one scale parameter. So, this distribution can describe a more diverse shapes of hazard function. In this skripsi, we will discuss how to construct inverse Weibull distribution and Generalized inverse Weibull distribution, and probability distribution function, cumulative distribution function, survival function, hazard function, and characteristics of these distributions. Parameter estimation of the generalized inverse Weibull distribution is using the maximum likelihood method."

"[ABSTRAKPada sistem tenaga listrik memiliki bagian yang saling berkaitan antara satu dengan yang lainnya yaitu sistem pembangkitan, sistem transmisi dan sistem distribusi. Untuk menyalurkan listrik ke konsumen dari sistem distribusi digunakan transformator. Apabila transformator terkena gangguan, maka konsumen dapat langsung merasakan dampaknya. Gangguan-gangguan ini dapat merusak transformator. Sehingga memprediksikan waktu kegagalan transformator sangat penting untuk dilakukan. Terdapat beberapa cara untuk memprediksikan waktu kegagalan transformator yaitu dengan menggunakan distribusi weibull dan distribusi eksponensial. Dengan membuat program aplikasi berbasis Microsoft Excel untuk kedua distribusi ini, dapat langsung memprediksikan waktu kegagalan transformator. Hasil dari program ini adalah kapan transformator akan mengalami waktu kegagalan. Apabila kedua distribusi ini dapat digunakan, program ini dapat menentukan distribusi yang paling akurat untuk digunakan. Sehingga waktu kegagalan yang didapat akan lebih akurat.

There are several ways to predict the time of the failure of a transformer is to use and distribution of the exponential and weibull distribution. By making an application program based on Microsoft excel for this distribution, a transformer failure can be directly predicted time. The result of this program will have the time when the transformer is going to failure. If both the distribution can be used, this program can determine the most accurate distribution to use. Therefore the time failure which were found would be more accurate., On an electric power system there are three parts interconnected between one and another and that is generation system, transmission system and distribution system.
