Faekhuna'a Village is one of the villages affected by asphalt oil spills. The oil spillage that has polluted the waters has led to a decline in the income of fishermen, due to the damage to coral reefs. To address this problem, direct implementation of the "one house, one coral transplantation" initiative using science and technology (IPTEK) can help mitigate the issues. The objective is to address the problem of asphalt oil spills through the application of IPTEK, optimize the role of the community, educate the community, and create a mindset among the community regarding the importance of environmental factors in the local economy. The method conducted by outreach and simulation. The stages are preparation, participation in the activities by the Faekhuna'a Village officials, 15 members of fisherman group (KUB), PPK 15 students of ORMAWA team and one supervising lecturer, lecturers and students from the University of North Sumatra's Off-Campus Study Program (PSDKU) in North Nias, and support from National Search and Rescue Agency (BASARNAS) of North Nias Regency. Through the program, providing education and awareness about the ecological aspects of life. The application of science and technology (IPTEK) has been warmly received by the community, who have actively contributed to ecosystem restoration through the PPK ORMAWA program. The fishermen has been educated about the crucial role of the coral reef ecosystem in improving the livelihoods. The use of IPTEK, specifically coral transplantation, has proven to be a viable, efficient, complex, adaptable, and compatible approach that is easily implementable.

Saat ini kelompok budidaya ikan koi di Desa Perbarakan masih terfokus pada proses pemijahan alami sehingga perlu penerapan teknologi pemijahan semi alami yang dinilai dapat meningkatkan kuantitas dan kualitas produksi ikan koi. Metode eksperimen lapangan yang dilakukan dengan melakukan perbandingan pemijahan alami dengan pemijahan semi alami menggunakan induk ikan koi yang siap dipijahkan dengan perbandingan 2 : 1 yaitu 2 ekor jantan (Kohaku dan Shiro) dan 1 betina (Tancho sanke doitsu) dengan melalui parameter pengamatan fekunditas, derajat pembuahan, daya tetas telur dan sitasan larva. Hasil variasi nilai fekunditas pemijahan alami adalah 7000 butir dan pemijahan semi alami adalah 14.000 butir, derajat pembuhan telur (FR) pemijahan alami adalah 71,42% dan pemijahan semi alami sebesar 85,71%, selanjutnya persentase daya tetas telur ikan koi pada pemijahan alami adalah 90% dan pemijahan semi alami sebesar 95% , sintasan larva tertinggi pada pemijahan semi alami 78,26% sedangkan pada pemijahan alami 44,44%. Sehingga penggunaan bantuan hormon ovaprim dinilai dapat menghemat waktu proses pemijahan dan tingkat keberhasilan lebih tinggi dibandingkan dengan teknik pemijahan alami

Binasi Beach is located in West Sorkam District, Central Tapanuli Regency, North Sumatra Province and borders the Indian Ocean. This beach is one of the beaches where several types of turtles land. Characteristics of the sandy substrate and coastal vegetation such as sea pine which is not too thick and the beach is sloping make turtles often land to lay their eggs. Semi-natural nests are widely used by conservation communities in an effort to protect endangered turtle eggs in natural habitats. This research was carried out from January to February 2022. The purpose of this activity was to determine the characteristics of the nesting habitat and the location of the turtle eggs (Lepidochelys olivacea) hatching as a turtle conservation area effort on the Binasi coast of North Sumatra Province. The method used is a descriptive survey method. Descriptive survey method is a method of collecting data by direct observation. The results showed a beach length of 1.50 m, narrow beach width, gentle beach slope, tidal type of semi-diurnal tide, white fine sand substrate and other parameters classified as normal for turtle nesting sites. The hatching rate of eggs at Station I is 100%, this is the highest value for each station, followed by station II which has the lowest hatching rate of 93.75% with a total average of 96.87%, this concludes that the success rate of hatching semi-natural eggs is very high good).

Afulu Village, located in Afulu Sub-district, North Nias Regency, has three interconnected ecosystems: coral reef ecosystem, seagrass ecosystem, and mangrove ecosystem. One of the main problems that occurs in Afulu Village is the damage to the coral reef ecosystem due to destructive activities such as the use of bombs, potassium, and poison by irresponsible people. This damage has caused the fishing grounds to become more distant, resulting in a decline in fishermen's catches from year to year. In addition, earthquakes and sedimentation events also have the potential to have a negative impact on coastal ecosystems such as coral reef ecosystems and mangrove ecosystems. These problems are exacerbated by the lack of community knowledge about coastal area management. To overcome these problems, this service activity aims to provide solutions to increase fishermen's catches through coral reef conservation management efforts. One of the innovations applied is the Science and Technology-based Coral Reef Transplantation Model Fish Apartment. The implementation method includes socialization, training and application of science and technology innovation of coral reef transplantation model fish apartment, as well as mentoring and evaluation. The main target of this activity is the Aman Setia Joint Business Group (KUB), which consists of fishermen groups in Afulu Village, Afulu District, North Nias Regency. It is expected that with the implementation of this activity, fishermen can maximize catches, increase daily income, and be able to disseminate information on science and technology innovations in coral reef transplantation model fish apartments to the people of Afulu Village. This is expected to support the recovery of ecosystem habitats independently and sustainably.
