Full text linkQuality degradation, modification, and habitat loss are significant threats to bird species. The natural habitat of birds has been modified into residential land and facilities to meet the needs of human life as happened at Tanjungpura University. This study aims to determine of birds species at Tanjungpura University. Observations were carried out from January to March 2019. The method used in collecting the data from bird was “Encounter rates” which was conducted in the morning starting at 6 – 9 am and at 3 - 6 pm. The data obtained were analyzed with the formula of simple abundance scale and frequency of attendance. The birds found at Universitas Tanjungpura are 28 species classified into 23 genera, 17 families, and seven orders. Birds found to have an abundance order scale are classified into abundant, general, frequent and, unusual categories. Birds included in the abundant category are Collocalia fuciphaga and Passer montanus. The types of bird foods at Tanjungpura University consist of frugivore, insectivore, granivore, herbivore, carnivore, piscivore, omnivore, molluscivore, and nectarivore. The value of attendance frequency have range between 10-100%. The bird species with highest frequency of attendance’s value is Passer montanus, Pycnonotus aurigaster, Pycnonotus goiavier, Collocalia fuciphaga, and Anthreptes malacensis

Full text linkShallots (Allium cepa var. Bauji) are plants that are included in the Liliaceae family. The dominance of peatlands in West Kalimantan is one of the factors causing the low production of shallot plants. This study aims to determine the effect and concentration of duck manure tricho-compost (TKB) on the growth of shallot plants in peatlands. The research was conducted from July to October 2019. The compositions used included distilled water, bran, dolomite, sugar, potato, duck dung, urea, TSP and KCL, Trichoderma harzianum isolates, liquid Trichoderma starter, peat soil, and shallot bulbs (Allium cepa var. Bauji). The study used a completely randomized design with six treatments in the form of negative control (-); 50 g of TKB; 100 g of TKB; 200 g TKB; 400 g TKB and positive control (+). The results showed that there was a significant effect between the application of tricho-compost duck manure on growth parameters. Tricho compost treatment with 100 g of duck manure was the concentration with the best results on the growth of shallots, with a height of 28.88 cm, number of leaves 19.88, total wetness of 15.99 g, wet tuber weight 5.37 g and wet root weight 0.69 g

Universitas Tanjungpura is an area with variable vegetation physiognomies that has the potential to have a lot of ant microhabitat. This study aims to determine the most effective method for collecting arboreal ants (Hymenoptera: Formicidae) found in the campus area of Universitas Tanjungpura. The study was conducted from August 2018 to February 2019 at ten locations based on their environmental condition. Ants were collected in three different methods: hand collecting, bait traps, and yellow pan traps. There were 39 species of Formicidae collectedfromall locations. These results were obtained by hand collecting (32 species), bait traps (32 species), and yellow pan traps (4 species). Hand collecting and bait traps are the most effective method for collecting arboreal ants in Universitas Tanjungpura
Isolasi dan Identifikasi Jamur Pada Buah Cabai Rawit (Capsicum frutescens L.) Yang Bergejala Antraknosa Dari Lahan Pertanian Di Dusun Jeruk
Full text linkAnthracnose is a disease that often attacks cayenne pepper (Capsicum frutescens L). This study aims to determine the species of fungus from the fruit of cayenne pepper with anthracnose symptoms. Fungal isolation was carried out using the direct plating method and fungal identification was carried out by observing the macromorphological and micromorphological characteristics of the fungi. The results showed that two fungal species were obtained, namely Colletotrichum sp (WA2) and Idriella sp. (WA3). Colletotrichum sp. (WA2) is a pathogenic fungus that causes anthracnose and Idriella sp (WA3) is a saprophytic fungus, but it is also known to be capable of being a pathogenic fungus

The highest reserve carbon was on street of Jalan Ahmad Yani 1 with the value of reserved carbon was around 236.71 ton C/Ha and the lowest reserved carbon was at the garden of Tugu Khatulistiwa, that was 18.42 ton C/Ha
Eksplorasi Bakteri Selulolitik dari Tanah Hutan Mangrove Peniti, Kecamatan Segedong, Kabupaten Mempawah
Full text linkPeniti Mangrove is one of the forests in West Kalimantan which has a high forest productivity rate. This highly supports the existence of cellulolytic bacteria, a cellulase-producing microorganism which can degrade cellulose into glucose. This research aims to measure the total density of bacteria, cellulose degradation power and the genera members of cellulolitic bacteria on Mangrove soils in Peniti, Mempawah. The soil samples were obtained through composite samplings, by setting 20 spots in four different locations: A,B,C dan D. Bacterial isolation was conducted using dilution technique and pour plate method on carboxy methyl cellulose (CMC) agar medium. The count of the density was done through total plate count (TPC) method. The degrading power was counted using cellulolytic index value. From the cellulose degrading test, 9 isolates of cellulolytic bacteria from 16 isolates were obtained. Cellulolytic bacteria isolates were characterised by colony morphology, cell morphology and biochemical tests. Through the identification process, 7 genera were identified: Aeromonas, Bacillus, Alcaligenes, Pseudomonas, Actinobacillus, Listeria and Chromobacterium
