Abstract

Penelitian ini berfokus pada pembahasan mengenai perhitungan premi asuransi jiwa gabungan dwiguna. Asuransi jiwa gabungan dwiguna memberikan dua manfaat sekaligus yaitu manfaat diberikan jika salah satu tertanggung meninggal dunia atau memberikan manfaat jika kedua tertanggung masih hidup hingga akhir masa kontrak asuransi. Perhitungan premi asuransi jiwa gabungan dwiguna ini melibatkan asumsi Gompertz pada probabilitas hidup dan pengaruh nilai tukar pada tingkat bunga. Perhitungan premi dihitung berdasarkan asumsi mortalita Gompertz, yang mempengaruhi probabilitas hidup tertanggung status gabungan. Selain itu, adanya pengaruh fluktuasi dollar terhadap tingkat bunga yang berdampak pada nilai premi asuransi. Berdasarkan hasil yang diperoleh, turunnya nilai tukar rupiah mengakibatkan tingkat bunga meningkat jika dibandingkan dengan tingkat bunga acuhan. Sehingga, dapat disimpulkan nilai premi asuransi dipengaruhi nilai tukar. Hal ini berakibat adanya peningkatan risiko yang dialami perusahaan asuransi.Kata kunci: asuransi jiwa gabungan dwiguna, hukum mortalita Gompertz, nilai tukar.

Abstract

Injective partial linear transformations in the vector space V and the function composition operations form semigroups called semigroups of injective partial linear transformations denoted by I (V). Suppose Z is a subspace in a vector space V, then the set of all members of I (V) whose function results are contained in Z to the function composition operation is also a semigroup denoted by I (V, Z) which is called a semigroup of injectable partial linear transformations with range restrictions. . In this article, we will examine how the characteristics of regular elements and the characteristics of two set members in I (V, Z) are related to Green using the literature study method. The results of the research in this article are the necessary and sufficient conditions needed so that any element is called a regular element and the characteristics of the two members of the set I (V, Z) are related.

Abstract

We studied the Leslie-Gower model of predator-prey with herd behavior. The square root functional response models predator and prey interactions that show herd behavior. This study aims to determine the formulation of the predator-prey model with herd behavior on prey, knowing the fixed points and its stability and simulating the model numerically. We found three fixed points that may exist: the extinction point of both species, the extinction of predator point, and the point of coexistence of the two species. The extinction of predator points is always unstable, while the point of coexistence of the two species can be stable under certain conditions. Due to the presence of square roots, the behavior of the solutions near the extinction point of the two species is not readily apparent. Numeric simulation shows that changing the initial condition and parameters can change the system's stability.Keywords: predator-prey; functional response; herd behavior; square root functional response, Leslie-Gower model. AbstrakArtikel membahas model predator prey Leslie-Gower dengan perilaku bergerombol pada prey. Interaksi predator dan prey yang menunjukkan perilaku bergerombol dimodelkan dengan fungsi respon akar kuadrat. Penelitian ini bertujuan untuk mengetahui formulasi model predator-prey dengan perilaku bergerombol pada prey, mengetahui titik ekuilibrium dan kestabilannya serta menyimulasikan model tersebut secara numerik. Hasil menunjukkan terdapat tiga titik tetap yang mungkin eksis, yaitu titik kepunahan kedua spesies, titik kepunahan predator dan titik koeksistensi kedua spesies. Titik kepunahan predator selalu tidak stabil, sedangkan titik koeksistensi kedua spesies bisa stabil dengan syarat tertentu. Karena adanya akar kuadrat, perilaku solusi di dekat titik kepunahan kedua spesies tidak mudah terlihat. Simulasi numerik menunjukkan bahwa perubahan nilai awal dan parameter dapat mengubah kestabilan sistem.Kata Kunci: predator prey; fungsi respons; perilaku bergerombol; fungsi respon akar kuadrat; model Leslie-Gower.

Abstract

The district map in Grobogan Regency can be optimized using the Greedy algorithm. The point on the graph represents the district and the line represents two areas that are directly adjacent. Greedy Algorithm is one of the algorithms developed to solve the problem of graph coloring to be able to produce minimal colors that are used without having the same color in areas that are directly adjacent. Greedy’s algorithm uses a set of color candidates and solutions in its solution. Staining is done at the point with the greatest degree followed by an examination of the appropriateness of the color with the principle that no neighboring points have the same color. The resulting color is included in the solution set. The process is continued until all the dots have been colored. Regional coloring in Grobogan district produces four colors with a greedy algorithm as the minimum color solution obtained

Abstract

Motivasi dan belajar merupakan dua hal yang saling mempengaruhi. Belajar adalah perubahan tingkah laku secara relatif permanen dan secara potensial terjadi sebagai hasil dari praktik atau penguatan yang dilandasi tujuan untuk mencapai tujuan tertentu. Kurangnya motivasi belajar siswa dapat terjadi akibat beberapa hal, salah satunya kurangnya inovasi dari guru dalam pelaksanan pembelajaran. Rendahnya motivasi belajar siswa ini terjadi juga di SD Negeri 1 Loram Kulon. Berdasarkan permasalahan tersebut, pelaksanaan pengabdian masayrakat di SD Negeri 1 Loram Kulon ini bertujuan untuk: (1) meningkatkan motivasi belajar siswa dengan pembelajaran berbasisi permainan tradisional (engklek); dan (2) sedangkan untuk guru diharapkan dapat menerapkan Pernainan Tradisonal (Engklek) Sebagai Media Pembelajaran. Maka dari pelaksanaan pengabdian masyrakat ini dapat memberikan pengetahuan dan pengalaman baru kepada guru maupun siswa.

AbstractThe disease caused by the virus has caused a continuous pandemic worldwide since 2012. In order to slow down the rapid spread of the virus, many countries have taken recovery measures. This paper aims to analyze the trends of modeling pandemic cases in Scopus-indexed journals. The research method is a literature review using a bibliometric analysis approach starting from defining the keywords modeling' and ‘pandemic' in the Publish or Perish application with Google Scholar as the database. After narrowing the results by selecting the topic of modeling the pandemic problem it consisted of 200 articles in total. After that, the metadata was compiled using the Mendeley application, the VosViewer application was used to create a research trend visualization. The results obtained by bibliometric analysis show that the number of publications continues to increase. Which journals are published, which organizations and countries publish the most, how the evolution of perspective has changed since 2012, and which articles are most cited. We conclude that since the pandemic, there is a possibility of an evolution in the quality of publications.Keywords: bibliometric analysis; pandemic; mathematical model; Mendeley; Publish or Perish; Vosviewer. AbstrakPenyakit yang diakibatkan dari virus telah menyebabkan pandemi berkelanjutan di seluruh dunia sejak 2012.
