This community service activity is Science and Technology Guidance and Training of Andaliman Plant Seed Germination Process (Zanthoxylum acanthopodium DC.) In Sitaratoit Village. Andaliman (Zanthoxylum acanthopodium DC.) Is a wild plant found in North Sumatra, Indonesia, the Rutaceae family. The Batak people use the fruit as a spice in their traditional cuisine. Breaking the seed dormancy period of andaliman plants is the initial treatment of the seeds intended to start the germination process, this effort can be in the form of physical, mechanical or chemical treatment. Andaliman plant germination is a process of growth and development of embryos that undergo changes where the plumula grows and develops into stems and radicles into roots. Dormancy is a state of stopping growth experienced by a living organism or its part in response to a condition that does not support normal growth. Thus, dormancy is a reaction to certain physical or environmental conditions. The trigger of dormancy can be mechanical, physical, or chemical. Specific objectives achieved were the provision of science and technology about breaking the seed dormancy period of andaliman plants to the people of Sitaratoit Village, Guidance to the Sitaratoit villagers about the seed germination process of andaliman plants, and the training of Sitaratoit villagers to cultivate andaliman plants. Specific target achieved is that the Sitaratoit Village Community can implement the cultivation activities of andaliman plants, andaliman plants in the Sitaratoit Village area can provide economic benefits for the community, andaliman plant management and cultivation are more noticed and known by the local community, and increase the percentage of seed germination of andaliman plants. The methods used in achieving the objectives of this activity are Village Potential Survey, Conducting dialogues through FGD program activities (Focuss Group Disscussion.), And Science and Technology based guidance and training. The stages of this activity are the Breaking of the Dormancy Period of the Seeds of Andaliman Plants, the Making of Planting Media for the Sprouts of Andaliman Plants, and the Making of the Andaliman Plant Shade. The results of this community service activity are the provision of science and technology about breaking the seed dormancy period of andaliman plants for 2 days to 18 people of Sitaratoit Village, 3 people from the village administration, and 3 students from private universities who are carrying out street vendors activities. The Sitaratoit Village community guidance about the process of seed germination of andaliman plants for 1 day the following day was also actively followed by the Sitaratoit Village community. And the training of the Sitaratoit Village community to cultivate andaliman plants for 1 day after 40 days later has also been carried out well and actively followed by the Sitaratoit Village community.Keywords : Andaliman, Seed dormancy, Seed germination.

The problem in this research is the low interest of physics student learning influence to the success of a process of physics learning. To overcome this problem, this research applied learning cycle model (Learning Cycle "5E"). This study aims to improve students' learning creativity, student learning activities, teachers' ability to manage learning and students' interest in physical learning through learning cycle model (Learning Cycle "5E") on Cubes and Balok subjects in class VIII-2 SMP Negeri 4 Angkola Timur. Data analysis shows that for the cycle I there is increase cycle II. The result of observation of student activity on cycle I obtained by cycle II increase. Observation on the ability of teachers to manage to learn in cycle I am in the category of "good," and for cycle II there is an increase that is in the category of "very good". The above conclusions suggest that the implementation of the learning cycle model (Learning Cycle "5E") can be used in an effort to increase the students' learning interest in physics and to the teacher, it is expected to implement the learning cycle model (Learning Cycle "5E") on other subjects on physics lessons or appropriate subjects. Keywords: Student Learning Interest, Learning Cycle Model "5e".

Pembelajaran yang bermakna salah satunya untuk meningkatkan kemampuan berhitung anak sekolah dasar di kelurahan pancuran pinang sibolga sambas kota sibolga mendorong diadakannya kegiatan Pengabdian kepada Masyarakat (PkM) dengan kondisi latar belakang ekonomi warga yang bertempat tinggal di kelurahan tersebut. Dengan pendidikan yang dirasakan oleh anak-anak belum maksimal. Anak-anak kurang menguasai konsep dasar dalam berhitung. Berhitung merupakan salah satu kemampuan matematika yang harus dikembangkan dan dikuasai pada setiap orang sejak berada pada usia dini. Bagi anak-anak berhitung merupakan pembelajaran yang membosankan, oleh karena itu diperlukan strategi belajar yang menarik dan menyenangkan. Berhitung termasuk salah satu kemampuan kognitif yang perlu dikuasai anak-anak. Pendidikan sekolah dasar (SD) di Indonesia saat ini mengharuskan siswanya selain sudah bisa membaca harus bisa juga berhitung. Oleh karena itu kemampuan berhitung sebagai kemampuan dasar harus dimiliki dan dikembangkan. Kelurahan pancuran pinang sibolga sambas berada di kota sibolga. Dimana di kelurahan ini terdapat anak-anak sekolah tingkat dasar yang masih kurang mampu dalam berhitung bahkan masih sulit dalam menyelesaikan perhitungan dalam pembelajaran matematika. Dengan dilaksanakannya KKN UM- Tapsel membantu anak-anak yang ada di wilayah kelurahan pancuran pinang sibolga sambas yaitu dengan membuat program PKM Bimbingan belajar khusunya dalam berhitung untuk anak tingkat sekolah dasar. PKM yang telah dilaksanakan memperoleh hasil yang maksimal baik, dilihat dari semangat dan antusian anak-anak peserta dalam setiap mengikuti proses bimbingan belajar berhitung hingga akhir.
