Abstract

Mangrove ecosystems contribute significantly to climate change mitigation because of their capacity to content carbon and sequestration large amounts of carbon dioxide (CO₂). This research was carried out to examine the carbon content and CO₂ sequestration of mangrove forests in the Essensial Ecosystem Area (EEA), Bagek Kembar, Sekotong, West Lombok. Data were collected through by applying a line transect approach in combination with plot based sampling. Carbon content and CO₂ sequestration were calculated using an allometric method based on equations established by the IPCC. Rhizophora mucronata emerged as the dominant species, representing 39.54% of the total number of individuals. The findings demonstrate that the mangrove forest within the Bagek Kembar EEA has a carbon content of  34.56 ton C/ha and CO₂ sequestration of 126.82 CO₂/ha. These findings indicate that the mangrove forest in the EEA Bagek Kembar play a crucial role in carbon content and CO₂ sequestration, thereby contributing to climate change mitigation while serving as a scientific foundation for the sustainable conservation and long term management of mangrove ecosystems.

Abstract

Pandanan Beach is a coastal area in West Lombok, Indonesia, where seagrass meadows provide habitat for various species of Echinodermata. However, information on the structure of Echinodermata communities in this area remains limited. This study aimed to analyze the community structure of Echinodermata in the seagrass meadow of Pandanan Beach, Sekotong District, West Lombok, based on species composition, density, species diversity, evenness, and dominance. Data were collected using a combination of line transects and 2 × 5 m quadrats. A total of 16 species comprising four classes Asteroidea, Echinoidea, Ophiuroidea, and Holothuroidea were recorded within the quadrats, with 803 individuals documented. The average density was 3 individuals/m². The highest relative abundances were recorded for Macrophiothrix sp. (33.00%) and Tripneustes gratilla (32.00%). The Shannon–Wiener diversity index (H′ = 1.82) indicated moderate diversity, while the evenness index (E = 0.66) suggested a moderately even distribution of individuals among species. The dominance index (D = 0.23) indicated that no single species strongly dominated the community. Two additional species, Ophiomastix elegans and Diadema savignyi, were observed outside the quadrats and were therefore excluded from the quantitative community analysis. These findings provide baseline information on Echinodermata community structure in the Pandanan Beach seagrass meadow and may support future monitoring and ecosystem management initiatives.

Abstract

Media pembelajaran Virtual Reality (VR) adalah teknologi yang memanfaatkan lingkungan simulasi 3D untuk menyampaikan informasi dan pengalaman belajar yang imersif kepada pengguna. Teknologi VR memungkinkan pengguna untuk berinteraksi dengan lingkungan yang diciptakan secara digital dengan menggunakan perangkat seperti headset VR. VR dalam konteks pendidikan dapat digunakan untuk menciptakan pengalaman belajar yang mendalam dan meyakinkan di berbagai bidang, mulai dari sains, sejarah, matematika, sampai pelatihan profesional. Kecenderungan gaya belajar siswa merujuk pada cara siswa lebih suka untuk mengakses, memahami, dan mengolah informasi. Tujuan dari kegiatan ini untuk memberikan sosialisasi dan implementasi bagi guru SMP dan SMA di kota Mataram yang selama ini belum menerapkan media pembelajaran sesuai dengan kecenderungan gaya belajar siswa. Hasil implementasi media pembelajaran tersebut nantinya diterapkan di kelas sehingga dapat meningkatkan kualitas pembelajaran khususnya pemahaman siswa terhadap materi. Metode pelaksanaan yang terkait dengan kegiatan sosialisasi dan implementasi ini adalah 1) observasi/analisis masalah, yaitu melakukan observasi/analisis masalah terkait dengan media pembelajaran yang telah diterapkan di kelas dan kecenderungan gaya belajar yang dimiliki siswa 2) menentukan solusi, yaitu berdasarkan hasil observasi/analisis masalah maka diputuskan untuk memberikan sosialisasi dan implementasi kepada guru SMP dan SMA di Kota Mataram mengenai media pembelajaran berbasis gaya belajar visual yaitu Virtual Reality (VR) yang dapat diterapkan di kelas dan 3) pelaksanaan kegiatan meliputi tahap persiapan, tahap observasi, tahap pelaksanaan kegiatan dan tahap penyusunan laporan.
