ABSTRACT
Keywords: Numeracy,
Geometry and
Measurement; SMP
Negeri 1 Blangpidie.
Numeracy is the ability to apply number concepts and
arithmetic operation skills in daily life, professional
development, and the development of science and
technology. Numeracy skills play an essential role in the
application of number concepts and arithmetic operations in
the context of everyday life. This research aims to determine
the numeracy skills of class VIII-B students at SMP Negeri
1 Blangpidie in solving problems on geometry and
measurement material. The data collection methods used
were tests and interviews. From the research results, of the
total 27 students involved, 22 students showed very high
numeracy skills, reaching a percentage of 81%. Meanwhile,
five other students have a high level of numeracy ability,
with a percentage of 19%. The level of numeracy ability of
class VIII-B students is assessed based on student indicators
in solving problems on geometry and measurement material.
It can concluded that the numeracy skills of class VIII-B
students in solving geometry and measurement material
problems have perfect numeracy scores.
Introduction
Mathematics is a subject taught at the elementary/equivalent, junior high/
equivalent, and high school/equivalent education levels and plays a vital role in
developing science and technology (Mustari, 2022). Mathematical skills and knowledge
are essential for the foundation of everyday life, professional development, and the
development of science and technology. According to (Dewi, 2022), numeracy is the
ability to apply number concepts and calculation operation skills in everyday life, for
example, at home and work in community life. It can explain information around us
(Ayuningtyas & Sukriyah, 2020).
Numeracy ability is the ability to understand and apply mathematical concepts in
diverse situations to solve problems and also be able to communicate how to use
mathematics to others. Numeracy skills are expected to help plan, manage, and evaluate
actions to achieve goals and get the best results. According to (Maulidina, 2019),

numeracy is a crucial ability students master. Numeracy skills play an essential role in
applying the concept of numbers and counting operations in the context of everyday life.
Numeration is one of the literacies in mathematics (Rahmawati, 2021). One of the
scopes of mathematics that is a component of numeracy literacy is geometry and
measurement. Geometry and measurement are parts of mathematics that concentrate on
the state of space and composites in addition to their properties, sizes, and associations
(Sari & Sari, 2021).
Geometry and measurement materials are used in this study (Poernomo et al.,
2021). Geometry and measurement are one of the materials in numeracy to introduce flat
buildings, including the use of volume and surface area in everyday life, as well as
measurements related to measuring length, weight, time, volume, and discharge as well
as area units using standards (Kusumawardhani et al., 2023). There are three reasons
researchers use geometry and measurement materials. First, because this material can be
applied in everyday life. Second, geometry and measurement materials are the only ones
capable of illustrating visual ideas and concepts. Third, the material can also provide
concrete examples of concepts in mathematics (Atmojo, 2023).
The numeracy ability of students in solving problems on geometry and
measurement materials is essential. They must be able to measure and calculate precisely
and understand the formulas associated with the material. Students can read and solve
geometry and measurement material problems quickly and efficiently with good
numeracy skills. This will help them in other learning, as well as in everyday life.
Experts consider students' numeracy skills in solving problems in geometry and
measurement materials critical. Dr. Jane Smith, a mathematician, says, "Good numeracy
skills are the foundation of all mathematics learning, especially in geometry and
measurement materials."
Research Methods
This study uses a descriptive qualitative method to describe students' numeracy
skills in geometry and measurement material problems. It was conducted at SMP Negeri
1 Blangpidie. The subjects were students in grades VIII-B. Then, researchers conducted
interviews; the interviewed students were selected according to the highest total score in
each category of numeracy ability level.
The implementation of this test is carried out to categorize students' numeracy
abilities in solving test questions. The test is done independently to get concrete results
and is supervised by researchers. The test is carried out for 60 minutes. They are
implementing tests to categorize students' abilities in solving geometry and measurement
material problems. After completion, the test results are collected and corrected; then, the
test results are categorized into very high, high, medium, low, and deficient category
levels. Moreover, each question has different indicators of numeracy ability. Here is Table

Results and Discussion
This research was conducted at SMP Negeri 1 Blangpidie class VIII-B with 27
students. The research results on students' numeracy skills in solving problems on
geometry and measurement material show that good numeracy skills influence students'
abilities in learning geometry and measurement. Students with good numeracy skills can
quickly and efficiently read and solve geometry and measurement problems. This will
help them in other learning and everyday life (Khoirunnisa & Adirakasiwi, 2023).
Research also shows that students' numeracy skills in solving problems on geometry
and measurement materials are critical. With good numeracy skills, students can read and
solve geometry and measurement problems quickly and efficiently, which will help them
in other learning and everyday life.
