Abstract

Kerusakan ekosistem mangrove di pesisir Pulau Batam menjadi masalah krusial yang berdampak pada lingkungan dan ekonomi masyarakat. Program Pemberdayaan Kemitraan Masyarakat ini bertujuan meningkatkan kapasitas kelompok masyarakat Akar Bhumi Indonesia dalam merehabilitasi mangrove dan pengelolaan sampah plastik secara berkelanjutan. Metode pelaksanaan meliputi tiga kegiatan utama: pelatihan penanaman dan perawatan mangrove, rehabilitasi mangrove dan workshop pembuatan paving block dari limbah plastik. Hasil kegiatan pemberdayaan kemitraan masyaraat menunjukkan 1).peningkatan signifikan pada pengetahuan mitra, dengan nilai rata-rata pre-test meningkat dari 47,25 menjadi 79,75 pada aspek pengelolaan mangrove dan pengolahan sampah plastik. Selain itu, kegiatan ini 2).berhasil mengurangi ±150 kg sampah plastik dan menghasilkan paving block yang dimanfaatkan untuk infrastruktur lokal dan 3).penanaman 750 pohon di area ±1.000 m², Program ini menunjukkan bahwa pendekatan edukatif dan partisipatif mampu memperkuat konservasi lingkungan dan memberdayakan masyarakat pesisir secara simultan.

Abstract

Mosque architecture, as a rich Islamic cultural heritage, contains numerous geometric elements that can be utilized as a source of contextual learning. However, the use of local architectural elements in mathematics learning has not been optimal, particularly in integration with digital technology. This study aims to explore geometric forms in the architecture of the Raja Hamidah Grand Mosque in Batam City through an ethnomathematics approach, and to dynamically visualize them using GeoGebra. The method used is qualitative with an ethnographic approach, through direct observation, documentation, and interviews with relevant parties. Data analysis techniques are carried out in three stages: data reduction, classification based on geometric categories, and interpretation.. The study results indicate that the ornaments and structures of mosque buildings contain concepts of plane shapes, solid shapes, as well as geometric transformations. GeoGebra is used to help visualize these geometric shapes dynamically and interactively. This study shows that the integration of ethnomathematics and digital technology can enrich contextual mathematics learning with local cultural nuances, as well as contribute to the preservation of Islamic architectural values.
