A study on community of phytoplankton in Diatas lake was conducted from April to September 2014. This study aimed to describe composition and structure of phytoplankton of the lake. We sampled phytoplankton at 6 stations purposively using plankton net that hauled vertically. We found 70 species of phytoplankton those belong to five classes, i.e. Bacillariophyceae (33 species), Chlorophyceae (27 species), Cyanophyceae (5 species), Dinophyceae (3 species) and Euglenophyceae (1 species). Total density of phytoplankton ranged from 881.06 to 3,196.02 ind/l. The highest density was at Station VI (Teluk Kinari) and the lowest one was at Station III (Muaro). Phytoplanktons with higher relative density (RD > 5 %) were Melosira italica, Synedra ulna, Melosira granulata (Bacillariophyceae), Staurastrum cereates, Chlorella vulgaris and Spirogyra fluviatis (Chlorophyceae). Shannon-Wiener Diversity index of phytoplankton (H`) ranged from 1.30 to 1.71 with the highest diversity index was at Station IV (Batang Hari) and the lowest was at Station V (central lake). Equitability index (E) was ranged from 0.39 to 0.57. Similarity index among stations were low which ranged from 34.48 to 62.50%.

Research about eggs hatching of olive ridley turtles (Lepidochelys olivacea Eschscholtz,1829) in the turtle conservation area of Pariaman City was conducted from October to January 2013. This research aims to determine a suitable location in eggs hatching of olive ridley turtles in the Turtle Conservation Area of Pariaman city. The research used experiment method with treatment A (beachsand near the shore) and B (beachsand near the sea), three repetitions in each location and 20 eggs per repeat. Results showed that the best location for hatching is beachsand near the shore with 80 % rate of hatching. The rate of hatching in beachsand near the sea is 37%. Environmental factors that influent rate of hatching are topography, temperature dan salinity.

Human activities along Batang Durian River can affect the diversity of aquatic organism, especially fishes. Fish diversity is the trophic characteristic based on its biological organisms that determine community structure. The research had been conducted from Mei to September 2016 to analyze the type of abundance, fish diversityand physical-chemical aspects of aquatic body. The research used survey method. Furthermore, the location and sampling effort were determined with purposive random sampling technique. Sample collection was set during 1 hour of catching till no more new species found in the three sampling location. The result revealed there were 9 species with 46 individuals in Batang Durian River. Diversity index in Batang Durian River was classified as medium with the distribution was even and no species dominated. The physical-chemical aspects of Batang Durian River were supposed to be able to support the live of aquatic organisms within. Human activities along the river body was fairly affecting fish diversity in it.

Kegiatan pengabdian ini bertujuan adalah untuk mentransfer pengetahuan dan teknologi serta berbagi pengalaman, penerapan ilmu, pengalian potensi diri dan pemecahan masalah yang terjadi di dalam masyarakat, terutama dibidang pertanian. Metode kegiatan yang dilakukan dalam bentuk penyuluhan, percontohan (demplot) dan pelatihan. Monitoring dan evaluasi kegiatan dilaksanakan sebanyak dua kali, yaitu pada saat survey pendahuluan dan pada akhir kegiatan pendampingan KKN mahasiswa Unand. Berdasarkan hasil survey dan data sekunder menunjukkan bahwa lapangan usaha pertanian setiap tahun mempunyai peranan yang paling besar dalam struktur perekonomian Kabupaten Tanah Datar. Berdasarkan distribusi persentase PDRB atas dasar harga berlaku, peranan lapangan usaha pertanian terhadap pembentukan PDRB Kabupaten Tanah Datar pada Tahun 2016 adalah sebesar 32,53 persen, sedangkan tahun 2017 adalah 31,55 persen atau mengalami penurunan sebesar 0,98 persen (Anonimus, 2017b). Iklim dan cuaca Tanah Datar yang mendukung serta keadaan tanah yang subur menjadikan lapangan usaha ini sebaga tumpuan dalam peningkatan kesejahteraan masyarakat, khususnya petani. Lapangan usaha ini perlu mendapat prioritas mengingat potensi sumber daya alam yang ada lebih banyak berada di lapangan usaha pertanian. Disamping itu, peningkatan bidang agroindustri dan agrobisnis juga dapat mendukung peningkatan nilai tambah lapangan usaha industri karena lapangan usaha ini termasuk lapangan usaha yang diandalkan dalam pembangunan prekonomian Kabupaten Tanah Datar di masa mendatang. Berdasarkan potensi daerah dan kondisi masyarakat di Nagari Pariangan tersebut, maka kami terdorong untuk melakukan kegiatan penyuluhan budidaya cabai merah di Nagari Pariangan, Kecamatan Pariangan, Kabupaten Tanah Datar, Sumatera Barat. Dari hasil kegiatan penyuluhan ini terlihat bahwa adanya sambutan dan antusias masyarakat untuk meningkatkan pengetahuan baik pada tingkat keluarga atau kelompok anggota masyarakat untuk mengembangkan budidaya cabai merah serta terjadi penurunan biaya produksi tanaman cabai, dengan demikian diharapkan terjadi peningkatan pendapatan petani cabai merah di Nagari Pariangan.

Seagrass bed on Karang Tirtas's coast consist of two species of seagrass namely Thalassia hemprichii and Enhalus acoroides. Thalassia hemprichii is the most dominating species with a frequency to be found about 96,3% while the frequency of Enhalus acoroides is 3,7%. Seagrass has ± 14 hektar distribution area with the pattern of distribution in group. The coverage of seagrass in Karang tirta's coastal included into poor cathegory. Meanwhile, the seagrass bed is one of the important ecosystem in the coastal area that are habitat for some other species and carbon sinc. Physical chemical factor's water of Karang Tirta's coastal area can support the growth of seagrass well except the temperature factor that is high.

This study was conducted with the aim of summarizing papers related to the distribution of the Dolphin Spinner (Stenella longirostris) in the Indian Ocean waters that had been discovered previously. The focus of the papers is to examine the distribution of S. longirostris with survey method data collection techniques. The existence of S. longirostris in the Indian Ocean waters is characterized by low levels of predation. The appearance of S. longirostris in Indian Ocean waters is located around the shore which is rich food sources at a depth of 0 - 250m. The data obtained shows in which years the distribution points in the Indian Ocean. The results obtained indicate that S. longirostris appears in the Indian Ocean almost every year.
