Abstract

Kemampuan berpikir kritis adalah salah satu kemampuan yang dibutuhkan di abad ke-21, sehingga menjadi seorang pemikir kritis merupakan salah satu tujuan sistem pendidikan di Indonesia saat ini. Hingga saat ini informasi yang tersedia mengenai deskripsi proses berpikir kritis calon guru matematika masih sangat terbatas. Di lain pihak, pembelajaran matematika dalam setiap jenjang pendidikan harus memberikan kesempatan untuk melakukan suatu kegiatan investigasi matematik. Tujuan dari penelitian ini adalah untuk mendeskripsikan proses berpikir kritis mahasiswa dalam memecahkan masalah investigasi matematika. Penelitian ini merupakan penelitian deskriptif yang menggunakan metodologi pendekatan campuran. Hasil penelitian menunjukkan bahwa terdapat 4 tahapan proses kognitif yang dilakukan mahasiswa ketika memecahkan soal investigasi matematik pada materi induksi matematika, yaitu spesialisasi, pendugaan, generalisasi, dan justifikasi. Pada tahap spesialisasi, mahasiswa cenderung mencoba beberapa kasus khusus untuk dapat menemukan pola secara umum. Pada tahap pendugaan, mahasiswa cenderung mencari pola dari beberapa kasus khusus yang ada untuk kemudian dirumuskan secara umum. Pada tahap generalisasi, mahasiswa merumuskan pola yang didapat secara umum. Terakhir, pada tahap justifikasi, mahasiswa membuktikan kebenaran rumus yang didapatkan dengan menggunakan induksi matematika. Beberapa kesalahan ditemukan dalam tahapan proses kognitif tersebut, antara lain kesalahan konseptual dan kesalahan procedural.

Abstract

A reinsurance company is a company that provides reinsurance services against the risks faced by the insurance company (the insured). An insured is obliged to pay an amount of money in accordance with the agreement as a form of obligation from the insured for his participation in reinsurance which is called a premium. One method that can be used to determine future premiums based on past experience is limited fluctuation credibility which can predict the value of pure premiums in the future based on current data and insurance manual rates. Using the help of the limited fluctuation credibility method, this study will calculate the estimated value of claim frequency, claim size, aggregate losses and pure health insurance premiums using reinsurance claim experience data. The results of these calculations will be analyzed for differences in value with the value given by reinsurance companies in Indonesia. With this research it is hoped that it can become a standard reference for the credibility of reinsurance companies in determining premiums in the future.

Abstract

Mathematical problems frequently arise in various scientific fields, particularly in determining the roots of nonlinear functions. Since complex nonlinear functions are often difficult to solve analytically, numerical methods are commonly used as an alternative approach. This article aims to compare the number of iterations and the error levels produced by the Newton-Raphson and Steffensen methods. The tests were conducted on three types of functions, polynomial functions of the form a1xn+a2xn-1+...+amx0, exponential functions of the form aebx+d+t and trigonometric functions of the form a0sin(b0x)+a1cos(b1x)+a2. For each type, three different functions were used, and each was tested with three different initial guesses. The results show that, in terms of iteration count, the Newton-Raphson method outperformed the Steffensen method for polynomial and trigonometric functions by 84% and 62%, respectively, while for exponential functions, the Steffensen method was superior by 12%. In terms of error, the Newton-Raphson method yielded smaller errors across all function types, with improvements of 92%, 84%, and 98% for polynomial, exponential, and trigonometric functions, respectively, compared to the Steffensen method.

Abstract

Mataram City as one of the tourist destination cities in West Nusa Tenggara has a variety of culinary attractions spread in various locations. The effectiveness of travel routes is an important factor in maximizing the culinary tourism experience, both in terms of travel time and cost efficiency. This research aims to apply Kruskal's Algorithm in determining the most effective culinary tourism travel route in Mataram City. Kruskal's algorithm, known as one of the methods in graph theory to find the minimum spanning tree (MST), is used to minimize the total travel distance between culinary location points. Location and distance data between culinary places were collected through field surveys and digital mapping. The results of the algorithm implementation show that the resulting route is able to connect all culinary points with a total travel distance that is more efficient than a random or conventional route of 15.09445 Km. Thus, the use of Kruskal Algorithm is proven effective as a solution in planning optimal culinary tourism routes in Mataram.
