Abstract

Penelitian ini bertujuan untuk membangun dan menganalisis model Matematika NQC pada pengaruh eksistensi live music terhadap perkembangan cafe di Kota Makassar. Selanjutnya dilakukan analisis model Matematika NQC dalam menentukan titik kesetimbangan, kestabilan model dan penentuan bilangan reproduksi . Simulasi dilakukan dengan menggunakan software Maple berdasarkan data primer yang diperoleh melalui kuisoner mulai Maret 2023 sampai dengan Mei 2023. Hasil penelitian ini diperoleh dari simulasi yaitu simulasi menggunakan strategi implementasi eksistensi live music. Pada simulasi tersebut diperoleh bilangan reproduksi dasar yang artinya bahwa tidak ada cafe yang sepi akibat pengaruh live music dan dalam jangka waktu tertentu cafe yang sepi pengunjung akan semakin berkurang atau bahkan menghilang dari populasi sehingga sangat besar pengaruh live music terhadap perkembangan cafe.

Abstract

The low numeracy literacy skills of students are due to the fact that the mathematics learning process has not yet produced the habit in students of reading with reflection and applying thinking and skills in understanding important information in solving problems. The aim of this research is to determine the increase in students' numeracy literacy skills through the application of problem based learning (PBL). This research is classroom action research that describes students' numeracy literacy abilities. The subjects of this research were class VIII students at SMP 1 Mamasa with a total of 15 students. The research results showed that the average numeracy literacy score in cycle I was 64.13 or in the medium category with 20% completeness. The average value of numeracy literacy in cycle II increased to 100 or was in the high category with 100% completeness. The increase in students' numeracy literacy skills was 35.87, which means that the problem based learning (PBL) learning model can improve the numeracy literacy skills of junior high school students

Abstract

The country of Indonesia is rich in culture where there are elements of mathematics in it. One of these cultures is Ulos cloth with various motifs. The results of this study of mathematics in culture can then be implemented in contextual mathematics learning by paying attention to cultural background, which is expected to facilitate and motivate students. The purpose of this research is to explain and expose the existence of ethnomathematics-based learning methods that associate elements of a culture with mathematical learning. With the existence of a culture, every person or individual can know everything that is contained in that culture. By choosing a topic about the cultural diversity of communities in the region of North Sumatra about the customary clothing of Ulos Batak, which in this study explains the existence of ethnomatematics contained in the motifs of the fabric of the Ulos of the Tribe of Batak Toba used in the wedding ceremony. The research method used is descriptive qualitative. The research also reveals how mathematical concepts are reflected in the fabric motifs of the outline, such as transformation, symmetry, and balance. This research uses data analysis techniques i.e. reduction, presentation and drawing conclusions. The data collection technique is carried out with the method of literature study where it is done by searching from various sources about Batak Toba's Modern Clothing then reduced by selecting the necessary information. Research results show that ethnomatematics is present in a variety of fabric motifs, including Passamot, Pengantin, Holong, and Sadum. By understanding the interrelationship between mathematics and culture in the context of the textile fabric, mathematical learning can become more interesting and meaningful for students. The research also emphasizes the importance of understanding and preserving the cultural heritage of the Batak Toba tribe.

Abstract

In learning mathematics, critical and logical thinking processes are needed to solve problems correctly, including material about arithmetic sequences and series, which requires good concentration in studying it. This type of research is descriptive qualitative which aims to analyze students' thinking processes in solving problems of arithmetic sequences and series. The subjects in this research were class XI high school students. One of the abilities developed in learning mathematics is the ability to solve problems. Students can do math problems but are not good enough at analyzing and thinking optimally. This causes students' low ability to solve mathematical problems. The research results showed that students were able to work on calculated reasoning cycle questions. Because, in responding to or answering these questions the subject will generally use ideas that have been researched, and the subject can communicate or understand the methods taken to overcome these problems. Some students who use a semi-reasonable reasoning cycle when evaluated in solving problems are not ready to communicate it in their own words. In understanding a problem, students have used these ideas but not enough and students cannot. don't understand the steps to solve this problem. The equation used is correct, but the steps to overcome it are still inappropriate.

Abstract

The research aims to describe the readiness, attitude and motivation of self-learning towards collaborative online based mathematics learning during the covid-19 pandemic. The researcher applies a quantitative descriptive methods in this study. Data collection has been done by giving three kinds of questionnaires including readiness, attitude and self learning motivation during covid-19 pandemic, and has distributed to 80 students in 3 Senior High School and 1 Vacational High School at Nuha district. The result of this research shows that the students are ready for Mathematics learning collaborative online based during covid-19 pandemic. That is supported by their ability to operate the computer and the usage of internet as well as their online learning experience they have been through for 2 years in online learning situation. Students' motivation towards learning mathematics through the implementation of online based collaborative learning is inconsistent even though it is in moderate level of motivation. Some students prefer the face to face learning process to online learning process and think that the previous learning will provide better learning outcomes. This is a challenge for teachers to prepare for the new normal phase with more interesting teaching material, strategies and learning methods by the development of digitalization of learning

Abstract

Insurance companies do not cover the entire risk of policyholders. The risk is generally transferred in part to the reinsurance company. Stop loss reinsurance is a form of reinsurance contract where there is a limit on the risk value that can be borne by the insurance company. This value is the retention value or retention limit in the reinsurance contract, which is the maximum risk or insurance value that can be borne by the insurance company. Determining the right retention value is very important. Optimizing the Value at Risk risk measure is one approach in calculating optimal retention. Optimal retention criteria were identified in this research so that optimal retention values ​​could be calculated. This research uses a large claim data sample with the Weibull distribution. Determining optimal retention depends on the distribution of claim sizes and loading factors (additional factors in the insurance policy). With a 95% confidence level, for loading factors of 10%, 15%, and 20%, the estimated optimal retention values ​​are $1,080.56, $1,393.54, and $1,567.20. This means that the risk transferred to the reinsurer is the remaining claim amount, if the claim size exceeds the optimal retention value.
