Study of meta-analysis by selecting the random effect model was employed to investigate and examine students’ education level predicted as one of the causative factors of the heterogeneity of mathematical critical thinking ability (MCTA) through problem-based learning (PBL). Search engines such as Google Scholar and Semantic Scholar were used to find thirty journal or proceeding articles published in 2011 – 2021 and indexed by Scopus, Sinta, and Web of Science. The Z and Q Cochrane test were used to analyze the data. The results revealed that education level was one of the significant factors causing the heterogeneity of students’ MCTA through PBL. Therefore, mathematics teachers or lecturers should minimize the gap by improving the learning quality through PBL in education level in which students’ MCTA was still low.

The progress or decline of a company is influenced by the productivity of the workers. The pension program is one of the programs that can guarantee the welfare of employees. This study aims to implement the Cox Ingersoll Ross (CIR) model in approximating interest rates and using them to determine normal pension contributions. In order to be able to describe the actual situation, namely the interest rate which is the basis for determining pension contributions is fluctuating, the CIR model was chosen. The method used in actuarial calculations in this study is the Projected Unit Credit method. Based on the calculations, the Mean Absolute Percentage Error (MAPE) value is 6.45%. This suggests that the pattern of forecasted interest rates and market rates move in much the same way. In addition, the results show that the calculation of normal contributions using the CIR model tends to be larger than using a constant interest rate. The forecast results can help reduce risks in the future.Keywords: Cox Ingersoll Ross (CIR), Normal Cost, Pension, Projected Unit Credit (PUC). AbstrakKemajuan atau kemunduran dari perusahaan dipengaruhi oleh produktivitas para pekerja. Program pensiun merupakan salah satu program yang dapat menjamin kesejahteraan pegawai. Penelitian ini bertujuan mengimplementasikan model Cox Ingersoll Ross (CIR) dalam mengaproksimasi tingkat suku bunga dan menggunakannya dalam menentukan iuran normal pensiun. Supaya dapat menggambarkan keadaan yang sebenarnya, yaitu tingkat suku bunga yang menjadi dasar penentuan iuran pensiun bersifat fluktuatif maka dipilih model CIR. Metode yang digunakan dalam perhitungan aktuaria adalah metode Projected Unit Credit (PUC). Berdasarkan hasil perhitungan, diperoleh nilai Mean Absolut Percentage Error (MAPE) 6,45%. Hal ini menunjukkan bahwa pola perkiraan suku bunga dan suku bunga pasar bergerak dengan cara yang hampir sama. Berdasarkan metode PUC, perhitungan iuran normal dengan model CIR cenderung lebih besar dibandingkan dengan menggunakan tingkat bunga konstan. Hasil perkiraan tersebut dapat membantu mengurangi risiko di masa yang akan datang.

This study is about analysis by creating a Nelson-Aalen curve and determining differences in the curve between categories of each risk factor for Type II Diabetes Mellitus. The analysis method used is the Nelson-Aalen method which is used to create a curve by calculating the cumulative hazard value first and then followed by calculating survival odds, and the Weighted Log Rank Test is used to determine the difference in the curve. The data used was the medical record data of inpatients with Type II Diabetes Mellitus at the Sayang Public Hospital of Cianjur Regency. The result obtained is that the Nelson-Aalen curve shows decreased characteristics, namely the longer the patient is treated, the patient's chances of recovery will be smaller. In other words, the patient's chances of returning home in a state of recovery will be even greater. Furthermore, the test results showed that there was no difference in the case of survival in the factors of age, hypertension, current blood sugar levels, and diabetic legs, while gender factors and balanced diet patterns showed a difference in the chance of survival, which means that both factors affect the chances of survival of Type II Diabetes Mellitus patients at the Sayang Public Hospital of Cianjur Regency.Keywords: Diabetes Mellitus, Nelson-Aalen, Survival Analysis, Weighted Log Rank Test. AbstrakPada penelitian ini disajikan analisa ketahanan hidup dengan membuat kurva Nelson-Aalen dan menentukan perbedaan kurva antar kategori dari setiap faktor risiko Diabetes Mellitus Tipe II. Metode analisis yang digunakan adalah metode Nelson-Aalen yang digunakan untuk membuat kurva ketahanan hidup dengan menghitung nilai hazard kumulatif terlebih dahulu lalu dilanjutkan dengan menghitung peluang ketahanan hidup. Weighted Log Rank Test digunakan untuk menentukan perbedaan kurva. Data yang digunakan adalah data rekam medis pasien rawat inap penderita Diabetes Mellitus Tipe II di RSUD Sayang Cianjur. Diperoleh hasil bahwa kurva Nelson-Aalen menunjukkan karakteristik yang menurun, yaitu semakin lama pasien dirawat maka peluang pasien untuk belum mengalami kesembuhan akan semakin kecil. Dengan kata lain, peluang pasien untuk pulang dalam keadaan telah mengalami kesembuhan akan semakin besar. Selanjutnya, hasil pengujian menunjukkan bahwa tidak terdapat perbedaan peluang ketahanan hidup pada faktor usia, hipertensi, kadar gula darah sewaktu, dan kaki diabetik, sedangkan faktor jenis kelamin dan pola diet seimbang menunjukkan adanya perbedaan peluang ketahanan hidup, yang artinya kedua faktor tersebut memengaruhi peluang ketahanan hidup pasien Diabetes Mellitus Tipe II di RSUD Sayang Kabupaten Cianjur.
