Abstract

Media pembelajaran berbasis teknologi merupakan salah satu hal yang penting dalam pembelajaran Matematika dan IPA di sekolah. Hal ini bertujuan untuk menciptakan suasana belajar yang menyenangkan, kreatif dan inovatif sehingga dapat meningkatkan motivasi dan hasil belajar siswa. Salah satu media pembelajaran Matematika dan IPA yang sering digunakan adalah aplikasi GeoGebra, yaitu aplikasi Matematika dalam kajian geometri dan aljabar. Namun data dan penelitian sebelumnya menunjukkan masih kurangnya penguasaan guru Matematika dan IPA dalam menggunakan software tersebut, khususnya di lokasi mitra pengabdian, yaitu di sekolah SD, SMP, dan SMA/MA Darunnajah, Jakarta. Oleh karena itu, pengabdi mengajukan untuk melaksanakan pengabdian dalam bentuk pelatihan pemanfaatan aplikasi GeoGebra bagi para guru sebagai solusi dari permasalahan tersebut. Kegiatan pengabdian tersebut berjalan dengan lancar, baik dari segi persiapan, pelaksanaan, maupun evaluasi. Hal ini ditunjukkan dengan hasil evaluasi dua arah antara pengabdi dan mitra pengabdian. Peserta mampu menjawab dan mempraktekkan secara langsung materi yang disampaikan pada sesi evaluasi. Selain itu, Berdasarkan jawaban kuesioner kepuasan/kesetujuan, secara kesuluran kepuasan peserta terhadap kegiatan yang dilaksanakan mencapai rata-rata yang cukup tinggi, yaitu mencapai 87,80%.

Abstract

Life insurance is an insurance product that provides guarantees in the form of benefits to the insured's family if the insured dies in the future. The amount of this benefit is influenced by the amount of the annual premium paid by the insurer to the insured. The researcher will calculate the amount of the individual's annual premium on endowment insurance. The researcher will use a fixed interest rate to calculate the discount factor and the Gompertz distribution approach to calculate the insurer's chance of survival. Previously, the researcher will estimate the Gompertz distribution parameters using the Maximum Likelihood Method (MLE) based on the 2011 Indonesian Mortality Table (female). Furthermore, the researcher will calculate the insurer's chance of survival using the Gompertz distribution to obtain the actuarial present value of the initial term annuity and the actuarial present value of the endowment life insurance. In addition, the researcher will calculate the comparison of the present value of the endowment life insurance to the present value of the life annuity. The last step is that the researcher will multiply the comparison of this present value by the benefits received to calculate the amount of the individual's annual premium. The calculation results show that the comparison of the present value of dual-purpose life insurance to the present value of a living annuity is getting smaller as the policy coverage period increases. As a result, the amount of the individual's annual premium will also be smaller. This shows that the amount of the annual premium is influenced by interest rate factors, the insurer's life chances, and the length of the coverage period.

Abstract

Technology-based learning media is one of the important things in learning Mathematics and Science in schools. It aims to create a fun, creative and innovative learning atmosphere so as to increase student motivation and learning outcomes. One of the learning media for Mathematics and Science that is often used is the GeoGebra application, which is the application of Mathematics in the study of geometry and algebra. However, previous data and research show that there is still a lack of mastery of Mathematics and Science teachers in using the software, especially in the location of service partners, namely in Darunnajah elementary, junior high, and high school schools, Jakarta. Therefore, the service proposed to carry out service in the form of training on the use of the GeoGebra application for teachers as a solution to these problems. The service activities ran smoothly, both in terms of preparation, implementation, and evaluation. This is shown by the results of a two-way evaluation between service and service partners. Participants are able to answer and practice directly the material presented in the evaluation session. In addition, based on the answers to the satisfaction / approval questionnaire, the participants' satisfaction with the activities carried out reached a fairly high average, reaching 87.80%.
