Abstract

Mangrove forests in Timbulsloko and Bedono villages have very important benefits in minimizing abrasion, due to tidal flooding and land absorption in this area. A large number of people have planted mangroves to restore the function of mangrove forests in coastal areas which conducted by NGOs, students, government agencies, and awareness from local residents. This study aimed to determine the dynamics of mangrove area and mangrove species dominant area changes in 2016, 2018, 2020 and 2022 based on Sentinel-2 Satellite Imagery processing, and to analyze the dynamic changes based on geospatial analysis. The method used in this study is divided into two: satellite imagery data processing and field survey. The result showed that the area of mangrove species in Timbulsloko and Bedono increased from 2016 to 2022. In 2016 the area of mangroves was 140.04 ha, 159.57 ha in 2018, 171.05 ha in 2020, and 234.8 ha in 2022. The use of Sentinel 2 Satellite Imagery to map the distribution of mangrove species dominant produce overall accuracy of 84.62%. The mangrove species with the highest area are Avicennia marina followed by Avicennia alba, Rhizophora apiculata, and Rhizophora mucronate. The increase in this area of mangroves in this area is due to natural additions and artificial additions due to mangrove planting conservation by several parties and the awareness of the local residents to protect mangroves.Keywords:Mangrove SpeciesDynamicsCoastal AreaSentinel 2Remote Sensing

Abstract

Total suspended solids (TSS) concentrations and distribution provide information to determine the quality of the carrying capacity of waters as marine resources. The purpose of the research is to analyze the concentration and distribution of TSS in marine waters due to anthropogenic impacts on land. The concentration and distribution changes of TSS were analyzed using a geospatial model approach. The in-situ data were collected in September 2023 at 14 stations in the east monsoon and analyzed in the laboratory using the gravimetric method. The results show that TSS concentration range from 29.2–52.6 mg/L. The distribution of MPT content in the Mojo River Estuary, Pemalang has several groups of stations with convergent forms, where the high source of MPT comes from around the lagoon, namely the aquaculture and mangrove areas, then in general it is also affected by waste from anthropogenic activities of the, surrounding industries seasonal currents, which are related to wind and seasons, as well as currents due to waters from tides.

Abstract

Penelitian ini bertujuan untuk mengevaluasi pembangunan Ekowisata Mangrove Park Kota Pekalongan dalam kaitannya dengan keberlanjutan lingkungan dan kepuasan pengunjung. Studi ini mengidentifikasi kendala yang dihadapi selama pengelolaan ekowisata, mengukur persepsi dan tingkat kepuasan stakeholder terhadap kondisi fisik, fasilitas, serta layanan yang tersedia, dan menganalisis dampak perubahan lingkungan terhadap ekosistem mangrove. Metode penelitian meliputi observasi lapangan, wawancara mendalam, dokumentasi, dan analisis data persepsi menggunakan skala Likert. Sepuluh aspek yang dianalisis menggunakan skala Likert mencakup atraksi wisata, kondisi alam, kebersihan, tempat ibadah, toilet umum, gazebo, area parkir, kondisi jalan dan aksesibilitas menuju lokasi, pemasaran ekowisata, serta keterlibatan masyarakat, menghasilkan beragam persepsi sesuai kategori interpretasi. Data nilai aset ekowisata menunjukkan bahwa ekowisata ini belum mampu mengoptimalkan potensinya karena keterbatasan jumlah pengunjung. Selain itu, perubahan lingkungan pesisir, termasuk kenaikan muka air laut dan penurunan tanah, memberikan dampak signifikan terhadap kondisi ekowisata, mengancam infrastruktur, dan menurunkan daya tarik kawasan. Dalam jangka panjang, tanpa mitigasi yang tepat, tren penurunan kualitas lingkungan ini dapat semakin menghambat keberlanjutan Mangrove Park. Oleh karena itu, diperlukan strategi rehabilitasi ekosistem, peningkatan kualitas fasilitas dan layanan, serta optimalisasi pemasaran untuk meningkatkan daya tarik ekowisata ini.
