The nonhomogeneous Poisson process is one of the most widely applied stochastic processes. In this article, we provide a confidence interval of the intensity estimator in the presence of a periodic multiplied by trend power function. This estimator's confidence interval is an application of the formulation of the estimator asymptotic distribution that has been given in previous studies. In addition, constructive proof of the convergent in probability has been provided for all power functions.

The Cattle Business Insurance Program is a protection cow yields program launched by the government to anticipate the risk of loss of farmer due to crop failure. The government started this program in 2015 by working together with an insurance company PT. Jasindo. This program is beneficial for farmer in Indonesia. Unfortunately, the impact of this program is still having a negligible effect on society because there is still a lack of attraction from the farmer to follow this insurance program. This research has a purpose in analyzing factors that caused the farmer’s interest, making them want to join this insurance. We use a structural equation model (SEM) of data that has been obtained to provide the method. Based on the results, we can conclude that the accuracy factor is a dominant factor that influences the farmer’s decision to join the AUTS program. This insurance has been beneficial in developing a better Cattle business insurance program in the future and motivates farmer to join this insurance. For insurance companies, this research has provided information for companies interested in opening similar and better insurance programs to increase the enthusiasm of local farmer and national cattle productions.

Pemahaman konsep matematika merupakan suatu aspek yang sangat penting dalam pembelajaran matematika. Dengan memahami konsep, siswa dapat mengembangkan kemampuannya dalam menyelesaikan permasalahan matematika. Hal ini sesuai dengan tujuan pembelajaran matematika yaitu memahami konsep dan menerapkan prosedur matematika dalam kehidupan sehari-hari. Kenyataannya, kemampuan pemahaman konsep matematika siswa masih tergolong rendah, sehingga dibutuhkan suatu model pembelajaran yang dapat meningkatkan kemampuan pemahaman konsep matematika siswa yaitu model pembelajaran Auditory Intellectually Repetition. Tujuan dari penelitian ini adalah untuk mengetahui perbedaan kemampuan pemahaman konsep matematika siswa SMP yang diajarkan melalui model pembelajaran Auditory Intellectually Repetition dengan yang diajarkan melalui pembelajaran konvensional. Metode penelitian yang digunakan adalah penelitian quasi experiment dengan desain control group pretest-posttest. Populasi dalam penelitian ini adalah seluruh siswa kelas VIII SMPN 13 Banda Aceh. Pengambilan sampel dilakukan dengan menggunakan simple random sampling, yang terdiri dari dua kelas yaitu kelas VIII2 sebagai kelas eksperimen dan kelas VIII1 sebagai kelas kontrol. Pengumpulan data digunakan dengan menggunakan lembar tes kemampuan pemahaman konsep matematika. Teknik analisis data yang digunakan adalah uji-t independen. Dari hasil penelitian dengan uji-t independen, kami memperoleh kesimpulan bahwa kemampuan pemahaman konsep matematika siswa SMP yang diajarkan melalui model pembelajaran Auditory Intellectually Repetition lebih baik daripada kemampuan pemahaman konsep matematika siswa SMP yang diajarkan melalui pembelajaran konvensional.

Inventory of raw materials is a big deal in every production process, both in company production and home business production. In order to meet consumer demand, a business must be able to determine the amount of inventory that should be provided. The purpose of this research is to choose an alternative selection of ordering raw materials that produce the maximum amount of raw materials with minimum costs. The raw material referred to in this study is pandan leaves used to make pandan mats. Analysis of raw material inventory used in this research was the Markov decision process with the policy iteration method by considering the discount factor. From the analysis conducted, it is obtained alternative policies that must be taken by producers to meet raw materials with minimum costs. The results of this study can be a consideration for business actors in the study location in deciding the optimal ordering policy that should be taken to obtain the minimum operational cost.

One of the premium determination techniques is to use credibility theory. In this study, a credibility premium determination model was derived with the best accuracy approach in the form of Bühlmann’s credibility premium. The claim data is assumed to have a Negative Binomial and 2-Poisson distribution. Bühlmann's credibility premium formula is given explicitly for these two data distributions. The obtained model is also applied to the correct data following these distributions. From the simulation results, it is obtained that the premium values are very close in value so that both models can be applied to the data and have a high level of credibility because they have a high credibility factor value.

One of the phenomenon in marine science that is often encountered is the phenomenon of water waves. Waves that occur below the surface of seawater are called internal waves. One of the mathematical models that can represent solitary internal waves is the modified Korteweg-de Vries (mKdV) equation. Many methods can be used to construct the solution of the mKdV wave equation, one of which is the extended F-expansion method. The purpose of this study is to determine the solution of the mKdV wave equation using the extended F-expansion method. The result of solving the mKdV wave equation is the exact solutions. The exact solutions of the mKdV wave equation are expressed in the Jacobi elliptic functions, trigonometric functions, and hyperbolic functions. From this research, it is expected to be able to add insight and knowledge about the implementation of the innovative methods for solving wave equations.

The ability of mathematical representation is one of the abilities that must be possessed by students in learning mathematics. In fact, students 'mathematical representation ability is still relatively low, so we need a learning model that can improve students' mathematical representation abilities, namely Model Eliciting Activities (MEA) with STAD type. The purpose of this study is to compare the mathematical representation ability of students taught using MEA with STAD type and those taught with conventional learning. The approach to be used is a quantitative approach with a quasi-experimental research method and using a control group pretest-posttest design. The population in this study were all VII grade students. Sampling was done using simple random sampling, which consisted of two classes, class VII1 as the experimental class and class VII2 as the control class. Data collection is used by using a mathematical representation ability test sheet. The data analysis technique used is independent t-test. Based on these analysis it can be concluded that the mathematical representation ability of students taught using MEA with STAD type is better than conventional learning.
