Graphs are one of the fundamental concepts in mathematics and computer science that represent relationships between objects. The structure of a graph consists of vertices (nodes) and edges that connect these vertices. With its ability to model various types of relationships and interactions, graphs have become an invaluable tool in many fields, ranging from mathematics and computer science to biology and social sciences. ...

The Golden Ratio, denoted by the symbol φ (phi), is a ratio that is considered highly aesthetic and has many applications in art, architecture, and nature. The value of φ, approximately 1.618, has existed since ancient times and has attracted the attention of many artists, scientists, and mathematicians throughout history. This concept symbolizes beauty and perfect proportion often found in various contexts. ...

The value of pi (π) is one of the most famous and influential mathematical constants, representing the ratio between the circumference of a circle and its diameter. Pi is an irrational number, meaning it cannot be expressed as a fraction of two integers, and its decimal representation never ends or forms a repeating pattern. In everyday practice, the ratio 22/7 is often used as an approximation for pi, although it is not entirely accurate. ...

Global climate change is increasingly worsening the conditions in the agricultural sector in many countries, including Indonesia. Unpredictable weather patterns—such as floods, droughts, and storms—often lead to crop failure, directly affecting food security. In facing this challenge, agricultural insurance has become a critical solution, especially for smallholder farmers who are most vulnerable to these risks. This innovation plays a significant role in protecting farmers from losses caused by natural factors while also supporting the achievement of several Sustainable Development Goals (SDGs), particularly SDG 1 (No Poverty) and SDG 2 (Zero Hunger). ...
Prime numbers are integers greater than 1 that can only be divided by 1 and themselves. Examples of prime numbers include 2, 3, 5, 7, 11, and so on. This property makes prime numbers unique and highly significant in mathematics, particularly in cryptography. The use of prime numbers in cryptography is applied in encryption algorithms that are used to safeguard data security. ...
