Abstract

Coral reefs are coastal ecosystems with the highest level of diversity with about one million species worldwide and are habitats for assemblages of millions of polyps that produce limestone to form their skeletons and develop into vast expanses of colonies. Corals are invertebrates belonging to the phylum Coelenterata (hollow animals) or Cnidaria. In order to preserve the coral reef ecosystem in the future in the Bahowo area, quantitative data is needed that can explain/describe the condition of coral reefs. The purpose of this study was to determine the condition of coral reefs, in this case, data on coral cover and associated biota in Bahowo waters. The data collection of this research used the UPT (Underwater Photo Transect) method. Analysis of the data in the form of research images using the CPCe (Coral Point Count with Excel extensions) application. The results of the analysis of the condition of coral reefs in Bahowo waters are in the damaged/bad category with live coral cover percentage data of 16.33%.Keywords: Live coral cover; Underwater photo transect (UPT); Coral reef condition; Bahowo watersAbstrakTerumbu karang merupakan ekosistem pesisir dengan tingkat keanekaragaman tertinggi dengan jumlah sekitar satu juta spesies di seluruh dunia dan merupakan habitat bagi kumpulan dari berjuta-juta hewan polip yang menghasilkan zat kapur membentuk skeletonnya dan berkembang menjadi hamparan koloni yang luas.  Karang adalah hewan tak bertulang belakang yang termasuk dalam filum Coelenterata (hewan berongga) atau Cnidaria.  Dalam rangka pelestarian ekosistem terumbu karang ke depan di daerah Bahowo, maka dibutuhkan data kuantitatif yang dapat menjelaskan/menggambarkan tentang kondisi terumbu karang.  Tujuan dari penelitian ini adalah untuk mengetahui kondisi terumbu karang, dalam hal ini data tutupan karang dan biota asosiasi di perairan Bahowo.  Pengambilan data penelitian ini menggunakan metode UPT (Underwater Photo Transect).  Analisis data berupa gambar penelitian menggunakan aplikasi CPCe (Coral Point Count with Excel extensions).  Hasil analisa kondisi terumbu karang di perairan Bahowo masuk dalam kategori rusak/buruk dengan data presentase tutupan karang hidup sebesar 16,33%.Kata kunci: Tutupan karang hidup; Underwater photo transect (UPT); Kondisi terumbu karang; Perairan Bahowo

Abstract

Coral recruitment is the entry of new coral individuals into coral reef populations due to reproduction or migration. Juvenile coral is the result of metamorphosis and growth of coral planula measuring 5 cm and attached to certain substrates. There are two types of substrates in the waters, stable substrates and unstable substrates such as rubble. The purpose of this study was to study hard coral recruitment, both in terms of density, the composition of juvenile coral colony types, size, and the type of substrate occupied by juvenile corals. This research was conducted in August 2021 in the waters of Molas, Bunaken District, Manado City. The method used for site selection is the purposive sampling method and data collection using a sampling method with quadrant transects. The results showed that the density of coral recruitment at the study site was 8,43 colonies/m2. The percentage of juvenile coral attachment on stable substrates is 90% and 10% on unstable substrates. The average size of juvenile corals at the study site was 2.4cm. The composition of the juvenile coral genus found at the research site were corals of the genus Acropora, Anacropora, Coeloseris, Cycloseris, Cyphastrea, Echinopora, Favites, Fungia, Galaxea, Goniastrea, Isopora, Leptastrea, Leptoseris, Lobophyllia, Merulina, Montastrea, Montipora, Oulophyllia, Pachyseris, Pavona, Platygyra, Plasiastrea, Pocillopora, Porites, Psammocora, Scolymia, Seriatopora, Symphyllia, and Trachyphyllia. Of the entire genus, corals of the genus Porites were dominated by the number of juveniles as many as 36 colonies.Keywords: Molas, coral, recruitment, ScleractiniaAbstrakRekrutmen karang adalah masuknya individu karang baru pada populasi terumbu karang dikarenakan reproduksi ataupun migrasi.  Juvenil karang merupakan bentuk hasil metamorphosis dan pertumbuhan planula karang yang berukuran ≤ 5 cm dan menempel pada substrat tertentu.  Terdapat dua tipe substrat di perairan, substrat yang stabil dan substrat yang tidak stabil seperti pecahan karang (rubble).  Tujuan penelitian ini adalah untuk mempelajari tentang rekruitmen karang keras, baik dari densitas, komposisi jenis koloni juvenil karang, ukuran, hingga tipe substrat yang ditempati oleh juvenil karang.  Penelitian ini dilakukan pada bulan Agustus 2021 di perairan Molas Kecamatan Bunaken Kota Manado.  Metode yang digunakan untuk pemilihan lokasi adalah metode purposive sampling dan pengumpulan data menggunakan metode sampling dengan transek kuadran.  Hasil penelitian menunjukan bahwa densitas rekruitmen karang pada lokasi penelitian sebesar 8,43 koloni/m2.  Persentase penempelan juvenil karang pada substrat stabil sebesar 90% dan pada substrat yang tidak stabil sebesar 10%.  Ukuran rata-rata dari juvenil karang pada lokasi penelitian adalah 2,4cm.  Komposisi genus juvenil karang yang ditemukan pada lokasi penelitian adalah karang genus Acropora, Anacropora, Coeloseris, Cycloseris, Cyphastrea, Echinopora, Favites, Fungia, Galaxea, Goniastrea, Isopora, Leptastrea, Leptoseris, Lobophyllia, Merulina, Montastrea, Montipora, Oulophyllia, Pachyseris, Pavona, Platygyra, Plasiastrea, Pocillopora, Porites, Psammocora, Scolymia, Seriatopora, Symphyllia, dan Trachyphyllia.  Dari keseluruhan genus, didominasi oleh karang genus Porites dengan jumlah juvenil sebanyak 36 koloni.Kata kunci: Molas, karang, rekrutmen, scleractinia

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.

This study aims to determine the differences in shell dimensions (length, width, and height) of Patelloida heroldi between two locations: an exposed intertidal stony shore and a sheltered intertidal stony shore. The research was conducted at Magarizaki Beach, Tomioka Peninsula, Amakusa, Japan, over two months from March to April 2024. Sampling was conducted using 25 x 25 cm quadrats along a line transect. The results showed that the average shell size of P. herolda at the exposed shore was 7.52 mm in length, 5.57 mm in width, and 2.23 mm in height, while, at the sheltered shore was 5.34 mm in length, 4.10 mm in width, and 1.81 mm in height. The shell size of limpets living on the exposed shore was significantly larger than those on the sheltered shore (t-student, P < 0.05). This study suggests that the difference in limpet shell sizes between the two locations was not influenced by population density, but was likely affected by differences in food supply and sedimentation levels in the areas. The impacts of environmental factors and food supply on the growth of limpets at the two locations are necessary to study in the future.

Penelitian ini dilaksanakan di Pantai Magarizaki, Semenanjung Tomioka, Amakusa, Jepang selama 2 bulan, Maret-April 2024. Metode yang digunakan yaitu metode sampling kuadrat dengan menggunakan transek garis dan kuadrat yang berukuran 25 x 25 cm. Hasil penelitian menunjukkan bahwa rata-rata ukuran cangkang Patelloida heroldi di pantai berbatu terbuka, yaitu masing-masing panjang, lebar, dan tinggi cangkang sebesar 7,52 mm, 5,57 mm, dan 2,23 mm, sedangkan yang di pantai berbatu terlindung, yaitu masing-masing panjang, lebar, dan tinggi cangkang sebesar 5,34 mm, 4,10 mm, dan 1,81 mm. Ukuran cangkang limpet yang hidup di pantai berbatu terbuka lebih besar dibandingkan dengan yang hidup di pantai terlindung (t-student, P < 0,05). Penelitian ini memperlihatkan bahwa perbedaan ukuran cangkang limpet di kedua lokasi tidak dipengaruhi oleh faktor kepadatan, melainkan diduga dipengaruhi oleh perbedaan suplai makanan dan tingkat sedimentasi pada kedua area pantai intertidal berbatu yang terbuka dan terlindung. Pengaruh faktor-faktor lingkungan dan suplai makanan terhadap pertumbuhan limpet pada kedua lokasi perlu diteliti lebih lanjut. Kata kunci: Cangkang, morfometri, pantai berbatu intertidal terbuka, pantai berbatu intertidal terlindung, Patelloida heroldi
