Abstract

Wildlife Sanctuary of Danau Pulau Besar Danau Bawah is surrounded by a forestconservation area of industrial timber estates and villages inhabited by indigenous peopleswhere their lives are very dependent on the forest. The consequence of these conditions is thatforest degradation is quite serious as the encroachment of trees and forest conversionpractices to agriculture and plantations. This study aims to gain estimation on forestencroachment and total loss of trees resulting in a decline in floristic diversity in this region.Data collection on forest encroachment map using satellite imagery analysis was done byusing Supervised Classification technique. The area assessed is conservation forest areaswhich has been encroached upon or degraded areas. Vegetation data were collected by usingthe plot method that illustrates the potential, type, density values, dominance of vegetationand its importance value index. The results of extensive analysis of vegetation encroachmentillustrated the potential value of forest degradation rate. Conservation forests area wasdegraded up to± 2339.73 ha or 8.29% of the total area, while the estimated loss due to theencroachment of trees during the period 1998 to 2012 reached 550,819.24 m3 or equal to39,344.23 m3 trees per year, or 3278.69 m3 per month and 109.29 m3 per day.

Abstract

Pests that are often a household problem in several cities in Indonesia are mosquitoes, rats, cockroaches, flies. Causes of settlement pests are dirty environments, food scraps, rubbish, and waterlogged gutters / ditches. The presence of pests in the house causes occupants to control pesticides. Pesticides are used primarily to control mosquitoes, ants, flies, cockroaches, mice and termites. This research is a descriptive research that aims to explain, detail and make a description of a phenomenon or object under study. The target population in this study is households residing in Pekanbaru City, namely in the Districts of Tenayan Raya, Sail and Pekanbaru City with three clean, medium and dirty categories. Determination of the sample is done purposively with multistage sampling technique. The sample was determined purposively with multistage sampling technique and the total sample was 101 households. The data obtained were nominal, ordinal and ratio, analyzed the relationship between these data using chi-square. The results showed that the physical environmental factors of housing settlements that affect the presence of residential pests are dirty environments caused by garbage and dirty drainage / ditches. Meanwhile, biotic environmental factors in residential housing that affect the presence of pests are plants grown in residential areas in the form of ornamental plants and unkempt shade plants. The dirty condition of the residential environment is due to the lack of environmental cleaning activities and the not yet routine transportation of waste from residential homes to landfills. In addition, there is less care for ornamental plants and shade in the yard, such as pruning.

Abstract

Information on meiofauna community structure in Indonesian mangrove areas is stilllimited compared to its vast areas. This study aimed to assess the community structureand abundance of meiofauna on four stations in mangrove areas, located in Teluk UmaVillage, Karimun Regency. Samples were collected from four stations. Station 1, 2,and 3 are dominated by mangrove vegetation Rhizophora sp., Avicennia sp., Bruguierasp., consecutively while station 4 is located in an area without mangrove vegetation(Coral Sand). Meiofauna abundance was analyzed using one-way ANOVA and Fisher'stest. The result indicated that meiofauna which were found at the study site consisted of12 taxa namely, Nematodes, Copepods, Polychaeta, Turbellarian, Cumacea,Oligochaeta, Holothuroidea, Syncarida, Isopoda, Ostracoda, Cnidaria, and Tardigrada.The average abundance of meiofauna was 3.22 ind/10 cm 2 . It was also found thatNematodes was the most abundance taxa followed by Copepoda and Polychaeta at allstations. One-way ANOVA results revealed that the abundance of meiofauna in eachstation was significantly different (F=3.52 P<0.05).

Abstract

Freshwater crab is widely distributed in river, lake, swamp, canal, and pond. Riau Province has many freshwater crabs, however biological information of these organisms are poorly known. This study aimed to understand the freshwater crab types from the Kampar Utara District, Riau Province. Samples from 14 sampling sites, in the Sawah, Sendayan and Sungai Jalau village had been collected from March to April 2013 using bamboo traps and scoop net. There were 178 crabs captured and all of them belonged to a single genus, Parathelpusa. Numbers of crab were obtained from the shallow riverines with numerous aquatic vegetation and no crab caught in the rivers. Based on the results, it can be concluded that the habitat of Parathelpusa in Riau is shallow riverine with dense aquatic vegetation.

Abstract

Batang Lubuh river has significant value to communities living close to the river. Generally, the people take some advantages from the river, such as for household activities (bath, washing and dumping the waste) and fishery. In addition, the river shed is such a beneficial for agriculture and mining. The use of macrozoobenthos as an indicator to identify the change of water quality was reported by some authors, but the information from Riau Province is scarce. The purpose or this research is to know the community structure or Macrozoobenthos at Batang Lubuh river, sub – district Rambah, Rokan Hulu Regency. Sampling was conducted using Eckman Grab 20 cm x 11 cm at 5 station along Batang Lubuh river of sub district Rambah, Rokan Hulu Regency. During this research we found two species of macrozoobenthos, Brotia costula family Thiaridae and Pila scutata family Ampullaridae. The abundance of macrozobenthos in study area was 408 ind/m2. Besides, we also found that Brotia costula as the dominant species. Regression analysis revealed that the correlation between physical and chemical factors such as temperature, brightness, depth, flow velocity, COD and phosphate on macrozoobentos was negative. In addition, DO and nitrate have a positive correlation to macrozoobenthos, while pH and turbidity have no correlation to macrozoobenthos.

Abstract

Potensi Pengembangan program pemberdayaan masyarakat harus berorientasi meningkatkan kesejahteraan masyarakat dengan menggunakan sumber daya yang ada. Program harus mempertimbangkan keunggulan yang dimiliki oleh suatu daerah. Oleh karena itu penting untuk melakukan analisis potensi desa sebelum mengambangkan sebuah program pengabdian kepada masyarakat. Kuliah Kerja Nyata (Kukerta) merupakan salah satu bentuk program pengabdian masyaraat yang dimotori oleh mahasiswa dan dibimbing langsung oleh Dosen Pembimbing Lapangan. Dari tahun ke tahun program Kukerta terus berkembang menyesuaikan kondisi yang ada. Dalam rangka untuk memasimalkan rancangan program yang dilaksanakan, perlu dilakukan analisis potensi desa terlebih dahulu. Dalam melaksanakan analisis potensi desa, focus pemetaan akan dilaksanakan pada sector (a) perkebunan dan pangan, (b) pariwisata, (c) tambang dan energi, (d) industry, serta (e) kesehatan. Lima indicator tersebut dijadikan sebagai acuan untuk penyusunan program. Data diperoleh melalui survey oleh mahasiswa Kukerta pada tahun 2022. Setelah itu data akan ditabulasi dan dipetakan untuk kemudian dijadikan bahan penyusunan model yang baru.
