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: Perhitungan Dana Pensiun Program Pensiun Normal dan Dipercepat Menggunakan Metode Cost Prorate Tipe Constant Percent dengan Beberapa Skenario Asumsi
Abstrak: Dana pensiun didefinisikan sebagai dana yang ditabung pegawai atau karyawan di masa produktif di mana hasilnya dinikmati ketika pegawai atau karyawan tersebut memasuki masa pensiun. Program pendanaan pensiun terbagi menjadi dua jenis, yaitu program pensiun manfaat pasti dan program pensiun iuran pasti. Penelitian ini membahas penggunaan metode Cost Prorate tipe Constant Percent dalam penghitungan aktuaria program pensiun manfaat pasti. Tujuan penelitian ini untuk menghitung besar manfaat pensiun, kewajiban aktuaria, dan iuran normal, serta memperlihatkan pengaruh kenaikan gaji dan inflasi terhadap besar kewajiban aktuaria dan iuran normal peserta program pensiun normal dan dipercepat. Hasil perhitungan memperlihatkan bahwa semakin cepat peserta memperoleh pensiun sebelum pensiun normal, semakin kecil manfaat pensiun, kewajiban aktuaria dan total iuran normal. Semakin besar tingkat kenaikan gaji dan inflasi, semakin besar pula kewajiban aktuaria dan iuran normal., Pension funds are funds invested by employees in their productive period, which the results are enjoyed by the employees after entering retirement. Pension funding programs are divided into two kinds, namely defined benefit pension plans and defined contribution pension plans. This study discusses the use of the Constant Percent of Cost Prorate method in actuarial calculation of defined benefit pension plans. The purposes of the research are to calculate the value of pension benefits, actuarial liability, and normal cost, and also to show the effect of salary increases and inflation on the value of the actuarial liability and normal cost of normal retirement and early retirement. The calculation results show that the sooner participants obtain pensions before normal retirement, the smaller the pension benefits, actuarial liability, and accumulation of normal costs. The higher salary and inflation, the higher the actuarial liability and normal cost.

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.
