Pandemik COVID-19 cukup mempengaruhi sistem pendidikan di Indonesia. Untuk memutus mata rantai penyebaran COVID-19 maka pemerintah dan praktisi pendidikan mencari solusi untuk kegiatan pembelajaran. Bichronous online learning banyak diimplementasikan dalam pembelajaran saat pandemik COVID-19. Namun pembelajaran seperti ini berdampak kepada kesehatan mental pelajar sampai dapat menurunkan motivasi belajar. Dalam penelitian ini peneliti menyebarkan kuesioner untuk mendapatkan informasi tentang motivasi berprestasi mahasiswa dalam bichronous online learning. Kuesioner terdiri dari 72 butir pernyataan dan responden terdiri dari 27 mahasiswa. Hasil penelitian menunjukkan bahwa motivasi berprestasi mahasiswa dalam bichronous online learning terdapat pada kategori cukup. Disimpulkan bahwa pembelajaran daring bichronous tidak menyurutkan motivasi berprestasi mahasiswa, namun tidak pula meningkatkan motivasi berprestasi mereka.

Background: Teachers as educators have challenges in their student's learning during the transition from a pandemic to a COVID-19 endemic. Therefore, strategies and innovations are needed to improve effective education, especially in increasing concentration and body fitness. This is also a problem faced at SDN Inpres Enemawira, Tabukan Utara District, Sangihe Islands Regency. Based on this, the team aims to introduce body stretching training as a physical activity to support learning more effectively. Methods: This service uses an educational approach with 11 stages of health planning. The data collection technique is an observation method with a success indicator of 80% of students' ability in body stretching developing as expected. This program targets students in grades 4, 5, and 6, held on July 23, 2022, by the service team of the Nusa Utara State Polytechnic. Results: The results of this activity were as many as 18 students participated in the activity. Then the evaluation results showed that the completeness of 88.9% of participants had developed in following and repeating body stretching movements for three repetitions. Conclusion: The introduction of body stretching activities can support learning more effectively than before being introduced to body-trying activities. It can be seen by increasing students' concentration power and physical fitness.

Dampak yang ditimbulkan oleh organisme penempel (biofouling) masih menjadi tantangan bagi nelayan pemilik perahu atau kapal. Pumpboat merupakan alat transportasi antar pulau dan sarana yang digunakan masyarakat pesisir kepulauan Sangihe untuk menangkap ikan. Biaya operasional yang tinggi seharunya tidak lagi ditambah dengan biaya pemeliharaan yang tinggi, sehingga nelayan dapat meminimalisir kerugian dimasa mendatang. Penelitian ini bertujuan untuk mengetahui daya tahan material plywood marine use yang biasanya digunakan nelayan Sangihe terhadap pertumbuhuan biofouling. Perendaman material yang sudah dicat dan dikeringkan dilakukan selama satu bulan. Perhitungan IS (intensitas serangan) dilakukan dengan mengumpulkan data luas permukaan material sebelum diserang dan setelah diserang setiap minggu. Hasil yang diperoleh yaitu minggu pertama 19.8 %, minggu ke-2 48.8 %, minggu ke-3 63.6% dan minggu ke-4 87.4%. Tingginya laju pertumbuhan ini mengharuskan pengaplikasian metode khusus, sehingga performa konstruksi dan mesin kapal tetap maksimal saat melaut.   The impact caused by adhering organisms (biofouling) is still a challenge for fishermen who own boats or ships. Pumpboat is an inter-island transportation tool and a means used by the coastal communities of the Sangihe Islands to catch fish. High operational costs should no longer be coupled with high maintenance costs, so that fishermen can minimize losses in the future. This study aims to determine the durability of marine use plywood material, which is usually used by Sangihe fishermen against biofouling growth. Immersion of the material that has been painted and dried is carried out for one month. The calculation of IS (intensity of attack) is done by collecting data on the surface area of ​​the material before being attacked and after being attacked every week. The results obtained are 19.8% in the first week, 48.8% in the 2nd week, 63.6% in the 3rd week and 87.4% in the 4th week. This high growth rate necessitates the application of special methods, so that the ship's construction and engine performance remains optimal while at sea.

Weight problems are often a concern for teenagers. Be it overweight or underweight. The GADIS (Balanced Diet Action) program counseling was carried out to increase knowledge about a healthy and balanced diet based on these problems. Including adolescents in the Sangihe Islands Regency, North Sulawesi Province, based on the results of dietary observations carried out, namely, eating one time a day to lose weight. The activity was conducted on February 11, 2022, at SMKN 3 Tahuna, Sangihe Islands Regency. Activities are carried out in counseling with lecture methods, discussions, and demonstrations. Sixty-nine students attended the training. The action results in the form of an increase in knowledge of 8.9 through the consequences of pre-test and post-test assessments. This activity aims to increase understanding about regulating the balance of nutrients through the type and portion of each person's needs.
