Abstract

Eyat Mayang is a hilly Village where landslides can occur during heavy rains. The rainfall makes the dike unable to accommodate the overflow from the river. This condition is exacerbated by the unavailability of a Garbage Final Destination (TPA), causing the community to throw their garbage in the river. In addition, silting of the river naturally occurs. Garbage piling and river siltation are the main causes for flooding. Based on data, in 2021 there were 2 floods that resulted in damage to infrastructure, housing, and public facilities, which caused substantial material losses beside the immaterial things. There were 785 families that were impacted by floods in 2021. Therefore, Students of Mataram University (UNRAM) who were conducting Integrated Community Service in the area Period of 2021/2022 carry out programs, one of which was called "Towards a Disaster Response Village" (DESTANA). This service is an effort to prevent the danger of flooding and land sliding in the future by planting a thousand trees at certain points agreed by the leadership, village officials, and the local community. The seedlings planted were provided by the Mataram Environment and Forestry Service, West Nusa Tenggara. This service is carried out in mutual cooperation with Bhabinsa, village officials, and the local community. Activities were conducted in stages in several designated hamlets. The community were very enthusiastic about the program with the hope that this program will be able to reduce or even overcome floodings and landslides. Moreover, we all hope that the Tree Planting Program increases the awareness of the communitiy about protecting the environment. We do hope that the trees will reduce the increase of global warming.

Abstract

Abstrak: Berdasarkan kajian nilai ujian nasional Sekolah Mengengah Atas (SMA) dan Madrasah Aliyah (MA) tiga tahun berturut-turut (2008-2010) untuk kompetensi dasar (KD) yang nilainya selalu rendah adalah KD Protista. Dari hasil penelitian tahun 2010, terungkap bahwa kegiatan parktikum (termasuk pengamatan Protista) tidak bisa dlaksanakan secara maksimal karena berbagai kendala seperti mulai dari tidak cukup tersedia sarana pendukung, tidak cukup waktu, dan tidak tahu bagaimana melakukan kegiatan tersebut. Karena itu diperlukan kegiatan khusus pengenalan fitoplankton sebagai salah satu upaya penguatan materi Protista yang menyangkut: pengenalan spesies yang umum dijumpai, sumber sampel, dan teknik pengamatan dengan mikroskop. Kegiatan pengabdian ini ditujukan untuk penguatan atau pengayaan pengetahuan dan keterampilan siswa MA Hidayatul Muhsinin Desa Labulia Lombok Tengah tentang fitoplankton sebagai komponen utama materi KD Protista. Kegiatan pengabdian ini akan dilakukan dalam bentuk penyampaian teori dan praktek pengamatan secara langsung menggunakan mikroskop. Siswa kelas III jurusan IPA (Biologi) MA Hidayatul Muhsinin, peserta kegiatan ini sangat bersemangat melakukan pengamatan di bawah mikroskop yang sebelumnya belum pernah mereka lakukan. Mereka baru sadar bahwa dalam satu tetes air terdapat banyak sekali individu sel berbagai spesies fitoplankton yang bisa disaksikan. Pembelajaran teoritis di kelas diperkuat dengan fakta yang diamati dengan mikroskop. Kata kunci: IPA(Biologi), Fitoplankton, Madrasah Aliyah, Penguatan, Protista, Siswa
