Full text linkThe existence of Ephemeroptera, Plecoptera and Trichoptera (EPT) macroinvertebrates in water can be used as the indicators to identify the water quality. This study aims to determine the diversity of Macroinvertebrates and physical and chemical factors in water of the Mentuka River. Macroinvertebrate sampling was carried out in February 2018 using random with surber and dip net at three stations spread overthe upstream, middle and downstream of the Mentuka River. The measurements chemicals and physical factors such as water temperature, brightness, current velocity, depth, TDS, TSS, acidity (pH), dissolved oxygen (DO) and free carbon dioxide (CO2), which is carried out together with macroinvertebrates sampling. There are 378 macroinvertebrates individuals belonging to nine genera, namely Polypedilum, Hydropsyche, Anthopotamus, Baetis, Acroneuria, Libellula, Rhyacophila, Parathelphusa and Macrobrachium in Mentuka River. The Ephemeroptera, Baetis is the most abundance with 5.76 ind/m2. Based on the diversity index, the Mentuka was categorized as moderately polluted river

Perkecambahan Benih Padi (Oryza sativa L.) Lokal Asal Kalimantan Barat Berdasarkan Tingkat Salinitas
Full text linkThe selection of variety of local rice from West Kalimantan is essential in order to increase the production of reice seed. Rice seed that is resistant to saline concentration is especially needed to increase production. The purpose of this research is to know the effect of salinity on the seed germination of local rice varieties from West Kalimantan. This research used rolled paper test technique with standing position, and the research design used was Completely Randomized Design (CRD) with NaCl treatment at 0 ppm (control), 2000, 4000, 6000, and 8000 ppm with 5 repetitions. The rice varieties that were used were Padi Putri, Padi Renggak, Padi Bungkok, Padi Gadis, Padi Waes, Padi Banjar, Padi Beras merah, Padi Kunyit and Padi Ketan. The research findings showed the presence of salinity-level effect on the growth of local rice seed germination. The nine varieties of local rice from West Kalimantan could survive in condition with NaCl solution concentration at the range of 2000 – 8000 ppm
PENGARUH TUMBUHAN KABOMBA (Cabomba aquatica Aubl.) TERHADAP KADAR TSS, DO dan COD LIMBAH CAIR LABORATORIUM KIMIA FMIPA UNTAN
Full text linkLaboratory is one of the producers of waste water with a high content of hazardous materials before being discharged into water bodies. One effort to process laboratory waste with phytoremediation is to use Kabomba plants (Cabomba aquatica Aubl). This study aims to determine the ability of Kabomba (Cabomba aquatica Aubl.) To see the influence of plants on the levels of Total Suspended Solid (TSS), Dissolved Oksigen (DO) and Chemical Oxygen Demand (COD) from the Untreated Chemistry Laboratory Liquid Waste of FMIPA. This study used a Completely Randomized Design consisting of five treatments of waste concentration: control, 25, 50, 75, 100%. Based on the results of the study, Cabomba plants (Cabomba aquatica, Aubl.) able to reduce TSS values by 37.67% and increase DO values by a percentage of 77.5% on day 5 of treatment but not yet able to reduce COD values and increase pH values
Pengaruh Konsentrasi Biourin Kelinci Terhadap Pertumbuhan Vegetatif Bayam Batik (Amaranthus Tricolor L. var. Giti Merah)
Full text linkBatik spinach (Amaranthus tricolor L.) is a plant that is rich in nutrients and can be used as diabetes medicine and dysentery. Therefore, increasing the growth of batik spinach plants needs to be done, one of which is the use of organic fertilizers, which can be used as rabbit biourin. The use of rabbit urine is done because rabbit urine has a high nutrient content compared to other livestock. The aim of the study was to determine the effect of biourin on the growth of batik spinach (Amaranthus tricolor L.). The study used a Completely Randomized Design (CRD) with 5 levels of concentration treatment consisting of controls, 25 ml / L, 30 ml / L, 35 ml / L, 40 ml / L, with 5 replications. The results showed that the administration of rabbit biourin significantly affected plant height, number of leaves, wet weight, dry weight and ratio of roots / canopy. The concentration of 25 ml / L gave the highest effect on the parameters of plant height, leaf number, root / crown ratio, wet weight, and dry weight
Jenis-Jenis Pakan Alami Leptobarbus melanopterus di Taman Nasional Danau Sentarum Kabupaten Kapuas Hulu
Full text linkAs the endemic fish of Danau Sentarum National Park, peam fish or Leptobarbus melanopterus had environmental problem such as overfishing due which threaten either juvenile or adult fish. These conditions were feared will led L. melanopterus population decrease in future if there is no sustainable management such as aquaculture. This research aims to identify the natural foods of L. melanopterus. Sixty four samples of L. melanopterus were collected through purposive sampling method. The results of gut analysis were found 17 genera of phytoplankton, 4 genera of zooplankton, 1 plant, and 1 Insecta. Zygnematophyceae had the most various genera which consisted of 7 genera while Ulvophyceae and Xanthophyceae only had 1 genera each of them. The natural food of L. melanopterus can be used as preliminary data for the application of aquaculture in the future
Pertumbuhan Tunas Lidah Buaya (Aloe barbadensis Mill.) Dengan Penambahan Naftalene Acetic Acid (NAA) dan Benzyl Amino Purine (BAP) Secara In Vitro
Full text linkAloe vera (Aloe barbadensis Miller) is one of plants consumed by many poeple. This plant can be regenerated using in vitro culture to get identical plants as their mother plants with many seeds in short time by adding NAA and BAP. This research work aimed to investigate the effect of NAA and BAP on growth of Aloe vera’s shoots. This research was conducted from December 2016 to January 2017 at tissue culture laboratory of Aloe Vera Centre Pontianak. The treatments were arranged in a completely randomized design with two factor. The first factor, NAA (0 M , 10-6M , 5×10-6 M , 10-7 M) and the second factor BAP (0 M , 10-6M , 5×10-6 M , 10-7 M) were aplicated. The research finding indicated that the single NAA and BAP treatmnet and their interaction did not give significant effect, however, the treatments descriptively enhanced growth of shoots, leaves, and roots contens. The treatment for of 0 NAA + 10 7 BAP and 10 -7 NAA + 10-7 BAP enhanced 1 shoot, the treatment of 5 × 10-6 NAA + 5 × 10-6 BAP generated 2,33 leaves, and concentrtion 5 × 10-6 NAA + 10-6 BAP generated 2,66 roots
Respon Pertumbuhan Sorghum (Sorghum bicolor (L.)) Varietas Kawali Pada Tanah Bekas Pertambangan Emas Rakyat
Full text linkSorghum (Sorghum bicolor (L.)) is a cereal food plantswhich can be utilized as heavy metal hyperacumulating plant. The research aims to find out the response of the growth of sorghum that cultivated on post gold mining soil (tailing). This research was conducted for 3 months from November 2016 to January 2017. It was done in the Greenhouse and Biology of Biology Departement in MIPA Faculity Universitas Tanjungpura Pontianak. Soil analysis was done in PT. Sucofindo Pontianak. This research used Completely Randomized Design (RAL) with five variations of soil sampling distance, namely P1 = 0 m, P2 = 75 m, P3 = 150 m, P4 = 225 m, P5 = 300 m. Each treatment was repeated three times, so there were 15 experimental units. The results show that sorghum can grow on soil sampling at distance 0- 300 m, but the best growth is at distance of 300 m. The further the distance from the tailing center, the vhiger the number of its leaves, height, wet weight, and dry weight
