Abstract

This study aims to determine the effectiveness of a community empowerment program using the Asset-Based Community Development (ABCD) method in improving the numeracy skills of second-grade students at SD Negeri 5 Jatimulyo, South Lampung, through Jarimatika. The research employed a descriptive approach following the ABCD stages, which include discover, dream, design, define, and destiny. The subjects of the study were 24 second-grade students aged 7–8 years. Data were collected through observation, interviews, documentation, and numeracy tests in the form of pre-tests and post-tests. The results showed a significant improvement in students’ addition skills and calculation speed after the program was implemented. The average pre-test scores increased by 41,38% across count components after participating in the finger-counting activities. In addition, students demonstrated enhanced fine motor coordination, improved learning focus, and greater enthusiasm during lessons. The ABCD approach also succeeded in increasing teacher and parent involvement in the learning process, thereby creating a more collaborative and sustainable learning environment. In conclusion, the ABCD-based community empowerment program proved effective in improving students’ numeracy skills and can serve as a creative and practical alternative learning method in elementary schools.ABSTRAKPengabdian ini bertujuan untuk mengetahui efektivitas program pemberdayaan masyarakat melalui metode Asset-Based Community Development (ABCD) dalam meningkatkan kemampuan berhitung siswa kelas 2 SD Negeri 5 Jatimulyo Lampung Selatan melalui kegiatan Jarimatika. Metode pengabdian menggunakan pendekatan deskriptif dengan tahapan ABCD yang meliputi discover, dream, design, define, dan destiny. Subjek pengabdian adalah 24 siswa kelas 2 yang berusia 7–8 tahun. Data dikumpulkan melalui observasi, wawancara, dokumentasi, serta tes berhitung berupa pre-test dan post-test. Hasil pengabdian menunjukkan adanya peningkatan signifikan pada kemampuan penjumlahan dan kecepatan berhitung setelah program diterapkan. Rata-rata nilai pre-test meningkat sebesar 41,38% aspek berhitung setelah mengikuti kegiatan Jarimatika. Selain itu, siswa menunjukkan peningkatan koordinasi motorik halus, fokus belajar, dan antusiasme dalam mengikuti pembelajaran. Pendekatan ABCD juga berhasil meningkatkan keterlibatan guru dan orang tua dalam proses pembelajaran, sehingga menciptakan lingkungan belajar yang lebih kolaboratif dan berkelanjutan. Kesimpulannya, program pemberdayaan masyarakat berbasis ABCD efektif dalam meningkatkan kemampuan berhitung siswa dan dapat dijadikan alternatif metode pembelajaran yang kreatif dan aplikatif di sekolah dasar.

Abstract

The increasing scarcity of clean water, exacerbated by population growth and climate change, calls for effective and efficient water management, especially at the household level. This study aims to develop a simple linear mathematical model to estimate daily household water consumption based on commonly observed domestic activities. The total water usage (W) is expressed as a function of key variables such as the number of residents, shower duration, laundry frequency, and dishwashing frequency, each multiplied by an empirical coefficient. These coefficients are drawn from published data to ensure representativeness. A case study conducted on a four-member household in Bandar Lampung, Indonesia, shows an estimated daily water consumption of 631.5 liters, aligning with global benchmarks. The study concludes that this linear model provides a practical and accessible framework for estimating household water use and can serve as a foundational tool for promoting water conservation strategies and informing public policy.

Abstract

Statistical literacy is one of the essential competencies that students must possess to face a data-based society in the 21st century. Various education policies in Indonesia, including the implementation of the Independent Curriculum and National Assessment, place the ability to understand, interpret, and use data as an important part of numeracy competence. In line with these developments, research on strategies to improve statistical literacy in secondary school students in Indonesia has increased in the last decade. This article aims to review and synthesize the results of research published in the 2015–2025 period regarding learning strategies used to improve statistical literacy of secondary school students. The research uses a narrative literature review approach through several stages, namely topic identification, collection of relevant publications, critical reading of the research content, grouping by theme, and synthesis of research results. The focus of the analysis included the learning strategies used, the research design, the factors that affect statistical literacy, and the implications of learning. The results of the synthesis showed that the most widely used strategies included Problem-Based Learning, Guided Discovery Learning, the use of PISA-type questions, and the use of digital technology. Factors that affect the successful implementation of the strategy include teacher competence, early math ability, learning motivation, digital literacy, curriculum support, and the use of authentic data in learning. This study shows that learning that is student-centered and emphasizes solving real problems has the greatest potential in improving statistical literacy. The research findings are expected to be the basis for teachers, curriculum developers, and researchers in designing more effective statistical learning ABSTRAKLiterasi statistik merupakan salah satu kompetensi esensial yang harus dimiliki peserta didik untuk menghadapi masyarakat berbasis data pada abad ke-21. Berbagai kebijakan pendidikan di Indonesia, termasuk implementasi Kurikulum Merdeka dan Asesmen Nasional, menempatkan kemampuan memahami, menafsirkan, dan menggunakan data sebagai bagian penting dari kompetensi numerasi. Sejalan dengan perkembangan tersebut, penelitian mengenai strategi peningkatan literasi statistik pada siswa sekolah menengah di Indonesia mengalami peningkatan dalam satu dekade terakhir. Artikel ini bertujuan untuk meninjau dan mensintesis hasil penelitian yang dipublikasikan pada periode 2015–2025 mengenai strategi pembelajaran yang digunakan untuk meningkatkan literasi statistik siswa sekolah menengah. Penelitian menggunakan pendekatan literature review naratif melalui beberapa tahapan, yaitu identifikasi topik, pengumpulan publikasi yang relevan, pembacaan kritis terhadap isi penelitian, pengelompokan berdasarkan tema, serta sintesis hasil penelitian. Fokus analisis meliputi strategi pembelajaran yang digunakan, desain penelitian, faktor-faktor yang memengaruhi literasi statistik, serta implikasi pembelajaran. Hasil sintesis menunjukkan bahwa strategi yang paling banyak digunakan meliputi Problem-Based Learning, Guided Discovery Learning, penggunaan soal bertipe PISA, dan pemanfaatan teknologi digital. Faktor-faktor yang memengaruhi keberhasilan implementasi strategi tersebut meliputi kompetensi guru, kemampuan awal matematika, motivasi belajar, literasi digital, dukungan kurikulum, serta penggunaan data autentik dalam pembelajaran. Kajian ini menunjukkan bahwa pembelajaran yang berpusat pada peserta didik dan menekankan penyelesaian masalah nyata memiliki potensi paling besar dalam meningkatkan literasi statistik. Temuan penelitian diharapkan menjadi dasar bagi guru, pengembang kurikulum, dan peneliti dalam merancang pembelajaran statistik yang lebih efektif.
