“…Moreover, the ecosystem also plays an important role in increasing water productivity by providing food for lobsters and other marine organisms. In addition, it is essential to provide natural lobster food and places for laying eggs to spawn [62]. The coral reefs' role in the survival of lobsters and marine life is also supported by [63] statement, where the role of coral reefs for lobsters (Panulirus spp.)…”

Lobster is one of the fisheries products which has become the most searched in international trade because of its high price. Therefore, the highest number of lobsters is from the natural fishing effort. The increasing market has an impact on decreasing habitat. Uncontrollable degradation impact requires an alternative to save the stability of lobster production in nature. This study aims to analyse the suitability of candidate locations for the placement of Lobster Artificial Reefs. The selection site uses the Stationary Visual Census method, while oceanography parameters use Water Quality Checker. Data collection was done in August and October 2021. The analyse suitability site was based on the bio-ecological parameters from some research stations. The research recommended all stations from 2014 to 2016 and FGD in July 2021. Recommendation site was found around Tiung Stone station. It is expected to be a protected area from predators, and it can be a feeding area to provide natural food during lobsters’ life cycle in nature. These results still need to ensure the effectiveness of the artificial habitat function for lobster breeding. Further analysis is required to see the effectiveness value of the location and lobster artificial reef before being implemented in other locations.

Efforts to mitigate damage to coral reef ecosystems can be made by developing techniques for coral transplantation. The purpose is to know the survival rate of coral Isopora palifera and Measure the length increase of coral Isopora palifera using the Image-J application as the measurement. The research method was that artificial blocks made of concrete were used as containers for the installation of 27 colonies of coral Isopora palifera. Data collection in the field in the form of colonies that were successfully transplanted to artificial reef units will be explored using a camera from each concrete block which will take perpendicular pictures and colony portraits from each artificial reef unit. The results are then analyzed using the Image-J application. The transplantation results survival rate in Isopora palifera coral colonies in Paputungan village is 66.6% of 100%, while the Isopora palifera coral colony increase length was around 1.51 mm/5 months or 0.302 mm/month. Keywords: Coral, Isopora palifera, Transplant, Concrete block, North Sulawesi Abstrak Upaya penanggulangan kerusakan ekosistem terumbu karang dapat dilakukan dengan menggembangkan teknik transplantasi karang. Tujuan adalah Mengetahui tingkat ketahanan hidup karang Isopora palifera dan Mengetahui laju pertambahan karang Isopora palifera dengan menggunakan aplikasi Image-J sebagai pengukuran pertumbuhan. Metode penelitian yaitu balok buatan dari beton dijadikan wadah tempat pemasangan karang Isopora palifera sebanyak 27 koloni. Pengambilan data di lapangan berupa koloni yang berhasil ditransplantasi ke unit terumbu buatan akan didokumentasikan menggunakan kamera dari tiap-tiap balok diambil gambar tegak lurus dan memotret koloni dari masing-masing unit terumbu buatan. Hasil pemotretan tersebut selanjutnya dianalisa menggunakan aplikasi Image-J. Proses transplantasi di desa Paputungan menghasilkan 66,6% dari 100% tingkat kelangsungan hidup pada koloni karang Isopora palifera, sedangkan untuk laju pertabahan koloni karang Isopora palifera berada disekitar 1,51 mm/5 bulan atau 0,302 mm/bln.

The formation of coral reefs is a long and complex process. The process of forming coral reefs begins with the attachment of various lime-producing biota on a hard substrate. Coral reefs take quite a long time to recover and are highly dependent on water conditions. Until now, pressures caused by human activities such as pollution from land and destructive fisheries practices have been considered a major threat to coral reefs. Efforts to overcome damage to coral reef ecosystems can be done by developing coral transplantation techniques. In response to this, the research wiil apply the method of artificial reefs from concrete blocks as a container for the installation of colonies of Acropora formosa spesies and Porites cylindrica spesies. A total of 75 branched coral colonies were transplanted in the waters of 75 branched coral colonies were transplanted in the waters of the Paputungan cape 39 colonies of branched growth forms of Acropora form and 36 colonies of branched grotwth forms of Porites cylindrica spesies were transplanted in artificial reef units. Data collection in the field in the form colonies that were successfully transplanted into artificial reef units totaling 6 units will be documented using cameras from each block taken perpendicular pictures and photographing colonies from earch artificial reef unit. The results of the shoot were then analyzed using software of the Image-J application. At the end of the observation process, it was found that the highest resistence of transplane colonies was 97.2 % where there were 35 surviving colonies and 1 dead colony out of a total of 36 colonies transplanted by Porites cylindrica spesies. Meanwhile, observations found that the lowest resistnce of transplant colonies that survived and 13 colonies that died out of a total of 39 colonies transplanted by acropora formosa spesies. Acropora formosa has a relatively fast increase compared to Porites cylindrica spesies. The highest accretion was dominated by the 18.05 mm fragment-size Acropora formosa spesies at the end of the sixth lunar observation.Keywords: Restoration, transplantation, Branching Coral, Tanjung Paputungan, North Minahasa ABSTRAKTerbentuknya terumbu karang merupakan suatu proses yang lama dan kompleks. Proses terbentuknya terumbu karang dimulai dengan penempelan berbagai biota penghasil kapur pada substrat yang keras. Terumbu karang membutuhkan waktu yang cukup lama untuk pulih kembali dan sangat tergantung dari kondisi perairan. Hingga kini, tekanan yang disebabkan oleh kegiatan manusia seperti pencemaran dari daratan dan praktek perikanan yang merusak telah dianggap sebagai ancaman utama untuk terumbu karang. Upaya penanggulangan kerusakan ekosistem terumbu karang dapat dilakukan dengan menggembangkan teknik transplantasi karang (coral transplantation). Menanggapi hal tersebut, maka dalam penelitian kali akan menerapkan metode terumbu buatan dari blok beton sebagai wadah untuk pemasangan koloni spesies Acropora formosa dan spesies Porites cylindrica. Sebanyak 75 koloni karang bercabang yang di transplantasi di perairan tanjung Paputungan 39 koloni bentuk pertumbuhan bercabang spesies Acropora formosa dan 36 koloni bentuk pertumbuhan bercabang spesies Porites cylindrica ditransplantasikan pada unit terumbu buatan. Pengambilan data dilapangan berupa Koloni yang berhasil di transplantasi ke unit terumbu buatan berjumlah 6 unit akan didokumentasikan menggunakan kamera dari tiap-tiap blok di ambil gambar tegak lurus dan memotret koloni dari masing-masing unit terumbu buatan. Hasil pemotretan tersebut selanjutnya dianalisa menggunakan sofware atau aplikasi Image-J. Akhir proses pengamatan ditemukan bahwa ketahanan koloni transplan tertinggi yaitu 97,2 % dimana terdapat 35 koloni yang bertahan hidup dan 1 koloni yang mati dari total 36 koloni yang di transplantasi spesies Porites cylindrica. Sedangkan pengamatan ditemukan bahwa ketahanan koloni transplan terendah yaitu 66,6 % dimana terdapat 26 koloni yang bertahan hidup dan 13 koloni yang mati dari total 39 koloni yang di transplantasi spesies Acropora formosa. Acropora formosa mempunyai pertambahan relatif cepat di bandingkan janis Porites cylindrica. Pertambahan paling tinggi didominasi oleh spesies Acropora formosa ukuran fragmen 18,05 mm di akhir pengamatan bulan keenam.Kata Kunci: Restorasi, Transplantasi, Karang bercabang, Tanjung Paputungan, Minahasa Utara
