Danau Aur memiliki biodiversitas yang kompleks baik jenis maupun manfaatnya. Salah satu yang menarik yaitu mikroalga, khususnya dari divisi Cyanobacteria. Tujuan penelitian ini untuk melihat keanekaragaman mikroalga divisi cyanobacteria di Danau Aur. Penelitian yang dilakukan dengan metode survei. Sampel diambil dari 5 stasiun dengan 3 ulangan. Mikroalga yang diperoleh diamati, diidentifikasi dan dianalisis dengan keragaman. Berdasarkan hasil penelitian, divisi Cyanobacteria di Danau Aur terdiri dari 2 kelas, 3 ordo, 3 famili, 5 genera dan 6 spesies. Mikroalga divisi Cyanobacteria yang ditemukan: Anabaena sp., Anacystis sp., Gelocapsa sp., Lyngbya sp., Oscillatoria sp. dan Oscillatoria limosa. Keanekaragaman tertinggi ditemukan di stasiun 1 (0,11) sedangkan keragaman terendah ditemukan di stasiun 2 (0,01). Hasil ini menunjukkan bahwa keanekaragaman mikroalgadivisi Cyanobacteria di Danau Aur rendah.

ABSTRAK Permasalahan yang dihadapi Kabupaten Musi Rawas Utara Sumatera Selatan tepatnya di Kecamatan Karang Jaya dan Rupit adalah pernah dilanda genangan air. Lokasi kedua mitra ini terdapat genangan air saat intensitas hujan deras. Padahal mayoritas penghasilan yang ada di lokasi tersebut petani. Jika terdapat genangan air maka petani rentan sekali terkena gagal panen. Dalam rangka membantu menyelesaikan permasalahan mitra, melalui program IbM ini tim memberikan bantuan alat Lubang Resapan Biopori (LRB), memfasilitasi pembuatan pupuk yang dihasilkan dari pengendapan sampah organik dari LRB, mengadakan pelatihan dan penerapan lubang resapan biopori di lokasi mitra. Metode yang digunakan dengan penyuluhan, pelatihan, demonstrasi dan demoplot. Hasil yang diperoleh dari program ini berupa pengenalan dan pemberian bor Biopori di 2 Kecamatan mitra (desa Terusan dan desa Beringin Jaya). Hasil IbM ini diketahui setelah adanya teknologi LRB laju infiltrasi tanah menjadi lebih baik, perencanaan jumlah LRB yang efektif untuk lahan perkebunan jeruk yaitu 597 LRB dengan memperhatikan kondisi intensitas curah hujan dan kondisi tanah pada kedua daerah tersebut. Topografis lahan perkebunan jeruk yaitu dataran datar dengan jenis tanah lanau, sampah organik yang diendapkan terbentuk kompos dan hasil tanaman cabai warga meningkat. Luaran kegiatan ini adalah teknologi tepat guna berupa alat bor biopori, dan kemampuan mengolah sampah organik berupa sampah sayuran, daun-daun kering, dan sampah buah menjadi pupuk kompos. Kata kunci: IbM, Banjir, LRB (Lubang Resapan Biopori) ABSTRACT The problem from Musi Rawas South Sumatera Utara precisely in Karang Jaya and Rupit was hit by a puddle. The location of both partners there are puddles when the intensity of heavy rainfall. Whereas the majority of existing income of farmers in these locations. If there are puddles of water that farmers vulnerable once exposed to crop failure. In order to help solve the problems of partners, through this IbM program team provides assistance tool Biopori Infiltration Hole (LRB), facilitating the manufacture of fertilizers produced from organic waste deposition of LRB, training and application of absorption holes biopores partner locations. The method used with counseling, training, demonstration and demoplot. The results obtained from this program in the form of recognition and awarding drill Biopori in 2 Subdistrict partners (village canal and village Beringin Jaya). The results of this IbM known after their infiltration LRB technology gets better, LRB number of effective planning for citrus plantation land, namely 597 LRB taking into consideration the intensity of rainfall and soil conditions in the two regions. Topographical citrus plantation is flat plains with silt soil type, organic waste is deposited to form compost and crop yields increased chili citizens. Outcomes of these activities is the appropriate technology in the form of a drill biopori, and ability to theprocess organic waste such as garbage vegetables, dried leaves, and fruit waste into compost.

The purpose of this study was to determine the effect of the Guided Note Taking learning model on the learning outcomes of biology students in class XI of SMA N 6 Lubuklinggau in the academic year 2017/2018. The design applied in this research is pretest-posttest control group design. The research sample was obtained using a random sampling technique. Namely students of class XI.IPA.4 as a control class and class XI.IPA.3 as an experimental class. To obtain student learning outcomes after treatment, a multiple choice test is used with a total of 26 items. The results of student learning data obtained through tests were analyzed using t-tests. The results of the t-test analysis showed that t-count> t-table (4.01> 1.68), it could be interpreted that the average value of the experimental class was greater than the average value of the control class. It can be concluded that the Guided Note Taking learning model influences the biology learning outcomes of Grade XI students of SMA Negeri 6 Lubuklinggau. Suggestions for improving student biology learning outcomes, teachers should innovate learning and apply active learning models. Keywords: learning outcomes, biology, guided note taking, models
