One of the functions of the forest is natural disaster such as flood control and the landslide that is how these forests absorb water into the root of the tree. Most forests in North Aceh Regency is protected forest which has undergone deforestation due to the presence of illegal logging and opening of new land like planting oil palm that impact against water infiltration. This research was conducted to identify deforestation forests in 2000, 2003 and 2015 using the techniques of remote sensing by satellite images landsat landsat 7 and 8. The method used was algorithm NDVI to get the classification of forest distribution and the level of deforestation forests based on the density of the vegetation from the Forestry Department 2003. Analysis of the rate of deforestation and loss of vast forests is done by leveraging the value of NDVI and other supporting data.The results showed that the NDVI value for forest distribution based on vegetation density in 2000 was -0,620438 � 0,628743, in 2003 between -0,364238 � 0,530055 and in 2015 between -0,274592 � 0,642049. The rate of deforestation in the district of North Aceh based on the value of the vegetation index (NDVI) yields 3 classes of deforestation are severe deforestation, light deforestation and not deforested, in 2000 there was deforestation of 25,62%, in 2003 it was 99,91% and in 2015 amounted to 15,89%, most deforestation occurs in production forests.
Kegiatan pengabdian kepada masyarakat berupa pelatihan pengukuran luasan sawah bertujuan memberikan solusi atas permasalahan terkait dengan luasan sawah di Desa Gunung Ketek dan Desa Dalam Kec. Samadua Kab. Aceh Selatan yang datanya tidak diketahui. Solusi yang ditawarkan berupa pelatihan pengukuran luasan sawah, sehingga dapat memberikan informasi kepada masyarakat Desa Gunung Ketek dan Desa Dalam tentang tata cara pengukuran lahan sawah serta dapat menganalisis luasan sawah dan mengetahui informasi luasan sawah dari hasil pengukuran menggunakan alat GPS. Metode yang digunakan berupa penyuluhan dan pelatihan. Adapun tahapan pelaksanaan kegiatan pengabdian, yaitu Adapun tahapan pelaksanaan kegiatan PKM ini, yaitu survey kondisi lahan sawah, mengajak aparatur kecamatan untuk mengarahkan batas lahan sawah yang akan diukur karena lahan sawah yang diukur berada di tiga Desa, yaitu Desa Gunung Ketek, Desa Dalam dan Desa Tengah yang termasuk wilayah Kec. Samadua Kab. Aceh Selatan. Lalu, melakukan pengukuran dengan pengambilan waypoint, yaitu dengan mengambil titik-titik batas lahan sawah yang diukur menggunakan GPS Garmin, dari hasil waypoint digunakan software map source dan software GIS. Berdasarkan hasil pelaksanaan kegiatan PKM berupa pelatihan pengukuran luasan sawah di Desa Gunung Ketek dan Desa Dalam Kec. Samadua Kab. Aceh Selatan, dapat disimpulkan bahwa luas lahan dan peta sawah ketiga desa tersebut didapatkan perhitungan luas lahan sawah di Desa Dalam adalah ± 1 Ha dan luas lahan sawah di Desa Gunung Ketek berkisar ± 11 Ha, sedangkan Desa Tengah diperoleh luas lahan sawah berkisar ± 2 Ha.
