Pola Pertumbuhan Ikan Peam (Leptobarbus melanopterus) di Taman Nasional Danau Sentarum Kabupaten Kapuas Hulu
Get PDFOverfishing has been being the major problem for Leptobarbus melanopterus population in Danau Sentarum National Park. This activity was feared could affect the declining of L. melanopterus population in the future. This research aims to determine growth pattern of L. melanopterus through length-weight relationship and relative weight analysis. The total of 64 fishes were collected which consisted of 32 males and 32 females. The range of male total length was 146-248 mm with weight was 40-170 gram, whereas total length female was ranging 141-299 mm with weight was 40-350 gram. Based on the regression analysis of length-weight data, the b value of male and female were estimated 2,46 and 2,81 respectively. Moreover, the b value of all samples without distinguishing sex type was 2,69 with relative weight was 101,33. The results of this research confirms that either females or males has negative allometric growth pattern
PENGARUH CEKAMAN SALINITAS GARAM NaCl TERHADAP PERTUMBUHAN KACANG TUNGGAK (Vigna unguiculata L. Walp) PADA TANAH GAMBUT
Get PDFVigna unguiculata L. Walp is one of the cultivated plants in West Borneo, usually cultivated on dry land in the dry season and can live on land that is affected by sea water intrusion. High salt levels in the soil can cause crop growth disorders. The purpose of this study was to determine the growth response of cowpea (Vigna unguiculata L. Walp) to the stress of salinity of NaCl. The study was carried out from 2019 to June 2019. Research was carried out using a Completely Randomized Design (CRD), which consisted of four treatments namely 0 ppm, 2500 ppm, 5000 ppm and 7500 ppm. The results showed a significant effect on the parameters of plant height, root length, number of leaves and wet weight, but no significant effect on the parameters of dry weight, root nodules and effective nodules
Identifikasi dan Deteksi Aktivitas Daya Hambat Bakteri Actinomycetes yang diisolasi dari Tanah Gambut di Desa Tajok Kayong Kalimantan Barat
Get PDFActinomycetes bacteria can grow well in soil media with acidic pH conditions such as peat soil. This study aims to determine the genus of Actinomycetes bacteria from peat soil.

Profil Hematologi Ikan Gabus (Channa striata Bloch, 1793)
Get PDFThe hematology profile that include hematocrite value, erythrocyte count, leucocyte count, differential leucocyte can used to determined the health state and diagnosis of fish diseases. The purpose of this research is to study the hematology profiles of gabus (C. striata). This research was conducted on August to October 2016. Gabus with body length about 25-35 cm and the blood samples were collected from vena caudalis (caudal vein) to evaluate hematocrite value, erythrocyte count, leucocyte count, eythrocyte and leucocyte diameter and differential leucocyte. The result of the research showed that hematocrite values 23,25-24,83%, erythrocyte counts 2,34-2,51x106cell/mm3, erythrocyte diameter 7,69-8,16 μm, leucocyte counts 1,53-1,65x105cell/mm3, leucocyte diameter 5,73-6,53 μm, monocytes 5,73-6,53%, limphocytes 76,13-78,20% and neutrophils 16,07-17,40%
Komposisi Dan Struktur Vegetasi Riparian Di Kawasan Taman Wisata Gunung Poteng Singkawang Kalimantan Barat
Get PDFRiparian ecosystem s an area that has ecological potential in supporting river ecosystems. This area is usually overgrown by various types of plants that have adapted to live in a place that is often inundated by river water, especially when it rains. Research on the composition and structure of riparian vegetation in Mount Poteng area was carried out in April - June 2017. The method used in this study was a line method with a combination of paths carried out in 4 locations. The width of each lane is 20 meters and the length is ± 100 meters. Results of the sample plot of 0.03 ha in riparian forest around the Poteng mountain area found a composition of riparian vegetation consisting of 23 species, 21 genera and 19 families.
