Judul: The Application of a Defined Benefit Retirement Plan at PT. Pertani (Persero) Based on the Indonesian Mortality Table IV
Abstrak: Setiap orang membutuhkan penghasilan untuk menghidupi kehidupannya dan kebutuhan tersebut tidak berhenti meskipun mereka sudah tidak lagi produktif bekerja. Diperlukan suatu cara untuk menjaga kesinambungan penghasilan di hari tua. Salah satu caranya yaitu dengan mengikuti program dana pensiun. Penelitian ini bertujuan untuk merumuskan dan melakukan penghitungan iuran dan manfaat Program Pensiun Manfaat Pasti (PPMP) PT. Pertani (Persero). Data yang digunakan dalam penelitian ini adalah data peserta PPMP pada tahun 2001-2020. Dana Pensiun PT. Pertani (Persero) merumuskan besarnya iuran dan manfaat pensiun, yaitu iuran sebesar 5% dari Penghasilan Dasar Pensiun (PhDP) dan manfaat pensiun sebesar 2.5% sebagai faktor penghargaan dikalikan dengan PhDP serta faktor penunjang lainnya seperti masa kerja, faktor nilai sekarang, dan faktor nilai sekaligus. Dalam penelitian ini juga dilakukan analisis terhadap keadaan pendanaan Dana Pensiun PT. Pertani (Persero) yang didapatkan hasil bahwa Dana Pensiun PT. Pertani (Persero) mengalami defisit pendanaan., Everyone needs income to support their lives, which doesn’t stop even though they are no longer productive. Needed a solution to maintain a sustainable income in old age. One way is by joining a pension plan. This study aims to formulate and calculate the contributions and benefits of Defined Benefit Pension Plan (PPMP) PT. Pertani (Persero). The data used in this study is the Defined Benefit Pension Plan participant data from 2001-2020. Pension Fund of PT. Pertani (Persero) formulates the number of contributions and pension benefits, namely a contribution of 5% from basic income (PhDP) and a pension benefit of 2.5% as an award factor multiplied by PhDP and other supporting factors such as years of service, present value factor, and a lump sum factor. This study analysis of the state of the funding of the Pension Fund of PT. Pertani (Persero) the results obtained are that the Pension Fund of PT. Pertani (Persero) experienced a funding deficit.

Judul: Optimizing Normal Pension Fund Financing Using the Actuarial Valuations Method with Variation of Assumptions
Abstrak: Program Dana Pensiun merupakan suatu upaya untuk mengantisipasi risiko pada masa pensiun dengan memberikan manfaat bagi karyawan yang pensiun. Penelitian ini membahas penghitungan aktuaria untuk program pensiun manfaat pasti dengan menggunakan metode Unit Credit (UC), Projected Unit Credit (PUC), Entry Age Normal (EAN), dan Attained Age Normal (AAN). Tujuan penelitian ini adalah melakukan penghitungan aktuaria yang mencakup penghitungan iuran normal dan kewajiban aktuaria serta menentukan metode yang optimal bagi peserta dan perusahaan berdasarkan pada akumulasi nilai iuran normal dengan tiga asumsi. Asumsi pertama adalah kondisi Indonesia 2020 yaitu suku bunga 10,24% dan kenaikan gaji 2%, asumsi kedua adalah suku bunga 8,34% dan kenaikan gaji 2% serta asumsi ketiga adalah suku bunga 6,06% dan kenaikan gaji 3%. Berdasarkan pada hasil penghitungan untuk masing-masing asumsi, metode EAN adalah metode yang optimal bagi peserta sedangkan metode UC adalah metode yang optimal bagi perusahaan., The pension fund program is an attempt to anticipate risks in retirement period by providing benefit the retired employees. This research discusses actuarial calculations for defined benefit pension plans using the Unit Credit (UC), Projected Unit Credit (PUC), Entry Age Normal (EAN), and Attained Age Normal (AAN) methods. The research aims to perform actuarial calculation including the calculation of normal cost and actuarial liability, and to determine the optimal method for participants and companies based on the accumulation of normal cost with three assumptions. The first assumption is the condition of Indonesia in 2020 with an interest rate of 10,24% and a salary increase of 2%, the second assumption is an interest rate of 8,34% and a salary increase of 2% and the third assumption is an interest rate of 6,06% and a salary increase of 3%. Based on the calculations for each assumption, the EAN method is the optimal method for the participants while the UC method is the optimal method for the companies.

Judul: Construction of Strongly Optimal Binary Linear Code with Minimum Distance 9 and 11
Abstrak: A binary linear code of length n over q F is a subspace of n q F . A code has three parameters that attached to it, namely length, dimension, and minimum distance. A code with length n, dimension k and minimum distance d is often called [n, k, d ]-code. Usually, when two parameters are given, then we want to find a code that has the best value for the last parameter. Based on Gilbert- Varshamov bound, if a [n, k, d ]-code exists and can not be expanded, we call it a strongly optimal code. In this paper, we construct strongly optimal code with minimum distance 9 and 11. In constructing the code, we created a theorem and algorithm based on Gilbert-Varshamov bound before we implement the algorithm to MAPLE programming language. Because of computational limitations, the program can only construct up to k = 10 for d = 9 and k = 12 for d = 11.
