Abstract

This research concerns the morphometry of seagrass E. acoroides (Linnaeus) Royle in 1839 in the coastal waters of Budo Village, Wori District, North Minahasa Regency. The existence of seagrass ecosystems in coastal waters is so important that it is necessary to carry out morphometric studies of seagrass, both for scientific purposes and for the sake of knowledge about seagrass itself. This research aims to describe the morphometrics of E. acoroides seagrass on the coast of Budo Village, Wori District, North Minahasa Regency, to compare the morphometrics of E. acoroides seagrass based on sampling stations, and to determine the condition of the aquatic environment (temperature, salinity, pH, substrate). The research location was divided into 3 sampling stations, namely the first mangrove area with 20 individuals, the second seagrass area with 30 individuals, and the third coral reef area with 10 individuals. The sampling process is carried out using a roaming survey method, the sample is washed and put into a plastic sample which will then be measured. The results statistically show that E. acoroides species in the coastal waters of Budo Village at three stations show significant differences in morphometric size, where station three is smaller than stations one and two. Environmental conditions and existing environmental parameters cause this. The condition of the environmental parameters at the three stations is still within safe limits, so it is still good for seagrass growth. Keywords: Seagrass, Enhalus acoroides, Morphometrics, Budo Village Abstrak Penelitian ini mengenai Morfometrik Lamun E. acoroides (Linneaus f.) Royle, 1839 di Perairan Pesisir Desa Budo, Kecamatan Wori, Kabupaten Minahasa Utara. Keberadaan ekosistem lamun di perairan pantai ini sangat penting sehingga perlu adanya kajian mengenai morfometrik lamun, baik untuk kepentingan ilmiah maupun untuk kepentingan pengetahuan tentang lamun itu sendiri. Adapun tujuan dari penelitian ini yaitu Mendeskripsikan morfometrik dari lamun E. acoroides di pesisir pantai Desa Budo, Kecamatan Wori, Kabupaten Minahasa Utara, Membandingkan morfometrik lamun E. acoroides berdasarkan stasiun pengambilan sampel,dan Mengetahui kondisi lingkungan perairan (suhu, salinitas, pH, substrat). Lokasi penelitian dibagi 3 stasiun untuk pengambilan sampel yaitu stasiun satu daerah mangrove dengan mengambil 20 individu, stasiun dua daerah lamun 30 individu, dan stasiun tiga daerah terumbu karang dengan mengambil 10 individu. Proses pengambilan sampel dilakukan dengan metode survei jelajah, sampel dicuci dan dimasukkan ke dalam plastik sampel yang kemudian akan diukur. Hasil yang diperoleh secara statistik bahwa spesies Enhalus acoroides di Pesisir Pantai Desa Budo pada tiga stasiun terlihat ada perbedaan nyata untuk ukuran morfometriknya, dimana stasiun tiga ukurannya lebih kecil dibanding stasiun satu dan dua. Hal ini karena kondisi lingkungan dan parameter lingkungan yang ada. Kondisi parameter lingkungan pada tiga stasiun masih dalam batas aman dimana masih baik untuk pertumbuhan lamun.

Abstract

The purpose of the study was to determine the type of mangrove, mangrove density, mangrove thickness, tides, associated biota objects, tourism suitability index, and carrying capacity of the Darunu mangrove tourism area.  The research period is October-December 2023.  The research methods used are cruising survey for mangrove species, line transect for mangrove density, remote sensing for mangrove thickness, and visualization for associated biota objects.  Data analysis for the tourism suitability index (IKW) and area carrying capacity (DDK) is guided by the provisions of Yulianda (2019).  The IKW value is 2.0 with the appropriate category and the DDK value is 25 people per day.  The size of the DDK value of the mangrove tourism area depends on two main factors, namely the length of tracking and the length of operating time.  The greater the value of tracking length and the length of operating time, the greater the DDK value, conversely the smaller the value of tracking length and the length of operating time, the smaller the DDK value.  As a recommendation to the village government to be able to extend the tracking distance by utilizing the mangrove spaces that are still available, in addition to the tourist period can be extended with adequate facilities such as electricity, lighting, etc. so that the value of DDK can still be achieved as much as possible to increase the economic income of the village community while still paying attention to environmental sustainability.  Furthermore, community participation to preserve this mangrove forest area is needed for the sustainability of ecotourism-based mangrove tourism at Darunu Mangrove Park. Keywords: Area carrying capacity, Darunu Mangrove Park, Ecotourism, Mangrove, Tourism suitability index. Abstrak Tujuan penelitian adalah untuk mengetahui jenis mangrove, kerapatan mangrove, ketebalan mangrove, pasang surut air laut, objek biota asosiasi, indeks kesesuaian wisata dan daya dukung kawasan wisata Darunu Mangrove Park.  Periode penelitian yaitu Oktober-Desember 2023.  Metode penelitian yang digunakan yaitu survey jelajah untuk jenis mangrove, transek garis untuk kerapatan mangrove, penginderaan jauh untuk ketebalan mangrove, visualisasi untuk objek biota asosiasi.  Analisis data untuk indeks kesesuaian wisata (IKW) dan daya dukung kawasan (DDK) berpedoman pada ketentuan dari Yulianda (2019).  Nilai IKW sebesar 2,0 dengan kategori sesuai dan nilai DDK sebanyak 25 orang per hari.  Besar kecilnya nilai DDK kawasan wisata mangrove tergantung pada dua faktor utama, yaitu panjang tracking dan lamanya waktu operasi. Semakin besar nilai panjang tracking dan lamanya waktu operasi, maka semakin besar pula nilai DDK tersebut, sebaliknya semakin kecil nilai panjang tracking dan lamanya waktu operasi maka semakin kecil nilai DDK tersebut.  Sebagai rekomendasi kepada pemerintah desa untuk dapat memperpanjang jarak tracking dengan memanfaatkan ruang-ruang mangrove yang masih tersedia, disamping itu periode waktu wisata dapat diperpanjang dengan dilengkapi fasilitas yang memadai seperti listrik, penerangan, dan lain-lain, agar nilai DDK masih dapat dicapai semaksimal mungkin dalam rangka peningkatan pendapatan ekonomi masyarakat desa dengan tetap memperhatikan kelestarian lingkungannya. Selanjutnya peran serta masyarakat untuk menjaga kelestarian kawasan hutan mangrove ini sangat dibutuhkan demi keberlanjutan wisata mangrove berbasis ekowisata di Darunu Mangrove Park. Kata kunci: Daya dukung kawasan, Darunu Mangrove Park, Ekowisata, Indeks kesesuaian wisata, Mangrove.

Abstract

Pemangkat is a coastal area in Sambas Regency which has a mangrove ecosystem. One of the biota found in mangrove forest areas is the Giant Mudskipper. This fish is often used as an environmental bioindicator due to its characteristics of living in the intertidal zone and being able to absorb and accumulate metals. Heavy metal pollution in marine and coastal areas has become a global problem that causes negative impacts on ecosystems, biota, and human health. One of the heavy metals that can pollute waters due to fishing and port activities is lead (Pb). Pemangkat is one of the centers of capture fisheries activities in West Kalimantan. Therefore, this research aims to analyze the content of the heavy metal of Pb in water, sediment, and Mudskipper in the Pemangkat mangrove ecosystem, Sambas, West Kalimantan. The Pb content in water, sediment, and Giant mud skipper samples was analyzed using an Atomic Absorption Spectrophotometer (AAS) at a wavelength of 283.3 nm. Accumulation of heavy metal in the biota was determined by the bioconcentration factor (BCF). The concentration of lead metal (Pb) in water and sediment samples was highest at Station II, such as 0.40 mg/L and 0.25 mg/L respectively. The metal content of Pb in Giant Mudskipper was highest at Station I (0.224 mg/kg). The BCF values for Giant Mudskipper at Stations I and II were 1.18 and 0.86. Keywords: Lead (Pb), Mangrove, Mudskipper, Boleopthalmus. Abstrak Pemangkat merupakan wilayah pesisir di Kabupaten Sambas yang memiliki ekosistem mangrove. Salah satu biota yang hanya ditemukan di daerah hutan mangrove adalah ikan tembakul.

Abstract

Community structure is an ecological term to indicate what organisms are present in a given environment, in what numbers, and how they are interconnected, through ecological indices that reflect dominance, evenness, and richness traits. The estuary is the most downstream part of the river and is connected to the sea. The Bahu River estuary is a habitat for a variety of aquatic life, especially fish, where water quality conditions greatly affect the abundance, diversity, and dominance. The methods used in this study were general field survey methods and fishing methods using the "swept area" method (Sparre & Venema, 1998). Data collection was carried out based on the time of collection using beach seine gear. This research was conducted with several stages, namely fishing in the field which will become data, data analysis and discussion. The results of this study indicate the composition of fish species in the Bahu River Estuary there are 11 families, 11 genus, and 14 species with a total of 86 individuals. The results of data analysis of the highest relative abundance in the Bahu River Estuary were in June, namely the Ambassis urotaenia species with a value of 45.90%. The results showed the community structure in the Bahu River Estuary in June and July (H' = 1.53 - 1.64, J' = 0.64 - 0.79, D = 0.31 - 0.26). Keywords: Diversity; Evenness; Dominance; River Estuary.
