Abstract

Bukit Tigapuluh National Park has an ODTW (Tourist Attraction) that is attractive for tourists to visit and has a unique tourist attraction, namely the Granit area, a former Granit mining area. One of the dominant plant species in the Granit area's tourist attraction in Bukit Tigapuluh National Park is Shorea spp. This study aims to determine the diversity of species and morphology of Shorea spp. in the Granit tourist area in Bukit Tigapuluh National Park, Riau Province. This study used a purposive sampling method using a pathway system. The composition of tree species uses manuals and tree species records to obtain observations of species diversity, while morphological observations can be taken using cameras or data from the Bukit Tigapuluh National Park as supporting material. The results showed that the morphology of each Shorea spp. Species seen from the shape of the leaves and stems had differences. The diversity of meranti species (Shorea spp.) In the Granit area of Bukit Tigapuluh National Park (TNBT) was eight species with 67 individuals. The index value of species diversity (H ') in Granit Bukit Tigapuluh National Park (TNBT) is line 1, which is 1.81 in the medium category, and lane two is 0.89 with the low category, and lane 3 is 0.82 with the low category. Keywords: Morphology, national park, shorea spp.

Abstract

Simpai (Presbytis melalophos)  or Sumatran surili is one of the primate species that has an important role for nature in the smooth process of natural forest succession. Simpai (Presbytis melalophos) is one of the endemic monkeys on the island of Sumatra from the family Cercopithecidae which is a rare and threatened primate based on the Regulation of the Minister of Environment and Forestry of the Republic of Indonesia Number P.20/MENLHK/SETJEN /KUM.1/62018. Camp Granite is one of the hoop habitat locations in Bukit Tiga Puluh National Park. However, until now there has been no information reporting research on hoops in the area. This study aims to find out information about the roaming area of the Simpai group (Presbytis melalophos) at Camp Granite Bukit Tiga Puluh National Park. The data collection in this study used a concentrated observation method with direct and hidden observations so as not to interfere with hoop activities. The data were analyzed using a geographic information system, namely the ArcGis 10.3 application. Based on the data results, the hoop group in the Camp Granite area has a roaming area of 3.66 ha. The range of hoops in thearea Camp Graniteis at coordinates S 00º 49' 42,240”, E 102º 31' 37,380”- S 00º 49' 53,040”, E 102º 31' 40,440” and S 00º 49' 46,620”, E 102º 31' 35,160”-S 00º 49' 50,400”, E 102º 31' 42,300”Keywords: Simpai (Presbytis melalophos), Roaming Area, Camp Granit.

Abstract

Batam City is an industrial city and has a total area of 1,570.35 km2 with a land area of 715 km2. Following the economic development and increasing population, the green open space in Batam City is decreasing. The purpose of this research was to analyze the adequacy of Batam’s green open space based on the criteria of Law No. 26 of 2007 concerning Spatial Planning and Minister of Public Works Regulation No. 5 of 2008 concerning Guidelines and Utilization of Green Open Space. This research was conducted with a spatial analysis method based on land cover information from the interpretation of Landsat 8 OLI image recording on 05-06-2018. Based on the results showed that Batam’s green open space is still 221.400 ha or 32.05% from land area. It means, Batam City’s open space is still sufficient at least 30% according to Law No. 26 of 2007 and Minister of Public Works Regulation No. 5 of 2008. The largest type of land cover in green open space is secondary dry land forest, covering 79.200 ha (11.45%). Keyword : Batam City, analysis, green open space.

Abstract

Ekosistem mangrove merupakan suatu komunitas tumbuhan yang khas, dipengaruhi pasang-surut air laut. Sungai Kembung merupakan salah satu ekosistem mangrove di Pulau Bengkalis dan saat ini cenderung mengalami tekanan seperti adanya aktivitas budidaya tambak udang dan penebangan liar. Penginderaan jauh dapat dijadikan sebagai solusi dalam pemantauan ekosistem mangrove. Penelitian ini bertujuan untuk memetakan penutup lahan mangrove Sungai Kembung menggunakan citra satelit Sentinel-2A dengan penerapan algoritma klasifikasi nearest neighbor. Segmentasi multiresolusi dengan nilai parameter scale yang berbeda (10, 30, 50, 100 dan 150) digunakan untuk menghasilkan objek penutup lahan. Hasil penelitian menunjukkan bahwa segmentasi terbaik diperoleh dari nilai scale 30 dengan jumlah objek sebanyak 10.750. Semakin besar nilai scale maka jumlah objek yang tersegmen semakin sedikit serta nilai akurasi keseluruhan yang dicapai cenderung menurun. Hasil perhitungan matrik kesalahan menunjukkan akurasi keseluruhan terbaik sebesar 74%. Penelitian ini merekomendasikan penerapan nearest neighbor sebagai algoritma klasifikasi alternatif untuk memetakan penutup lahan mangrove.

Abstract

The sumatran elephant is rare animals wich spreadin almost all parts of sumatera island. The conflict between people with the sumatran elephants often occurred in the forest area alongside people settlement. The large amount of sumatran elephants population in Tesso Nilo National Park highly dependent on the carrying capacity of the habitat and the available feed. This research aims to know populationof sumatran elephants and carrying capacity of feedthe sumatran elephantin the area of Tesso Nilo National Park Province of Riau. The studywas usedthe method purposive sampling by determined the position of elephant on the track, determinationof sample plot offeed location the sumatran elephants and carrying capacity collected of feed the sumatran elephant. Data obtained areComposition Vegetation (species density, species frequency, species dominance), IndexValue Important (IVI), Species Diversity, Biomass Feed, CarryingCapacity of Feed and Carrying Capacity of habitat. The result of interviews with the mahout in the village Lubuk Kembang Bunga, there are 2 groups the sumatran elephants with the total as many 38 tail. The results of the research showed that the availability of feed in 1 Hectare areasin a Tesso Nilo National Park were not sufficient to 1 tail sumatran elephants.The carrying capacity of habitat sumatran elephant wich exists at Tesso Nilo National Park regional with broad area 1331.19 Hectare can not accommodate for sumatran elephants. Keywords: elephant, location, population, feed.
