Get PDFThe agroecosystem is an ecological system that exists within the agricultural environment and one of the natural systems that occur after it is formed by the human. The Dayak people plant local rubber and are left to grow without intensive care along with various types of pioneering plants, fruit trees and woody trees. The aim of the study is to determine the composition and vegetation. The method used in this study is purposive sampling. The results are that there are 36 species consisting of 33 genera and 23 families. Generally, there are 16 tree species, 17 pole species, 18 stake species, and 16 seedling species. The most dominant families in the Nanga Pemubuh Village in all growth rates comprise 3 families, namely Arecaceae, Dipterocaearpace, and Moraceae with each number including 4 types of vegetation. The diversity of vegetation species of rubber agroecosystem is rated as medium or stable values (H' tree = 2,339, H' pole = 2,294, and H' stake = 1,652). Uniformity of the vegetation species of rubber agroecosystem is relatively high 0.794-0.941 and there is no dominance (C) in all growth rates 0.107-0.224
Pertumbuhan Tanaman Bayam Kuning (Amaranthus blitum L.) dengan Pemberian Pupuk Organik Cair Dari Kulit Kecambah Kacang Hijau (Vigna radiata L.)
Get PDFYellow spinach (A. blitum L.) is a rarely cultivated plant in West Kalimantan. To overcome this situation, farmers can use Liquid Organic Fertilizer (LOF). This research aims to find out the effects of LOF from The Hulls of Mung Bean Sprouts towards the growth of Yellow Spinach Plant and to find out the concentration of LOF from The Hulls of Mung Bean Sprouts which generates the highest growth on yellow spinach plant. This research was conducted from February to April 2017 in Biology Laboratory of Mathematics and Natural Science Faculty, Tanjungpura University Pontianak. This research used completely Randomized Design which consisted of 5 levels of treatment that are without LOF (control), LOF 55 (P1), LOF 60 (P2), LOF 65 (P3), and LOF 70 ml/L (P4). Each treatment was given 4 times so there were 20 units of experiment. The results show that the giving of LOF with 60 ml/L of concentration offered a significant effect towards all growth parameters. The optimum results of the average height of the plant was 20.17 cm, the number of leaves was 17.25, the shoot wet weight was 6.65 g, the shoot dry weight was 0.69 g, the root wet weight was 16 g, and the root dry weight was 9.50 g

Get PDFBasal stem rot is one of the diseases in siamese citrus (Citrus nobilis var. microcarpa) wich is caused by fungi Phytophthora sp. Im5. Phytophthora sp. Im5 growth can be inhibited by utilizing natural antifungi compounds deried from plant extracts. One of the plants that has potential to be antifungi is siamese citrus peel. This research aimed to find out the effect of ethanol extract in siamese citrus peel on inhibiting the growth of fungi Phytophthora sp. Im5. This research was conducted for 2 months from March to April 2017 in Microbiology Lab of Mathematics an Natural Science Faculty Tanjungpura University and in Plantation Processing Laboratory of State Polytechnic Pontianak. The research used completely randomized design with 4 treatments, namely control, siamese citrus extract 0,55 g/ml, 0,65 g/ml and 0,75 g/ml. The results show that the inhibition of the growth of fungi Phytophthora sp. Im5 with concentration of ethanol extract of 0,55 g/ml, 0,65 g/ml and 0,75 g/ml was not significantly different between treatments, but significantly different from control. A concentration of 0,55 g/ml is the best concentration to inhibit the growth of fungi Phytophthtora sp. Im5 with a percentage of inhibitory power of 78,41% and the activity level was very strong
EFEKTIVITAS Pseudomonas sp. BOT4 DALAM MENDEGRADASI MINYAK JELANTAH MENGGUNAKAN SUMBER NITROGEN NATRIUM NITRAT DAN YEAST EXTRACT
Get PDFJelantah is the residual waste of cooking oil. The disposal of untreated waste directly into the environment has the potential to promote damage such as water channels clogging and water body pollution. Form of waste treatment such as biodegradation can be done using potential bacteria such as Pseudomonas spp. which has been known for being effectively in decomposing organic waste. This study aimed to observe the ability of Pseudomonas sp. BOT4 in degrading jelantah with different nitrogen sources i.e. NaNO3 and yeast extract. This study was carried out from August to October 2018. The used cooking oil samples were homemade with deep frying method and the isolate samples were collected from used cooking oil-contaminated sewer water. Split plot design was used with time of incubation as main plots and nitrogen sources as subplots. The parameters observed were cell density and degraded oil weight. The results obtained stated that nitrogen sources of NaNO3 and yeast extract given optimum effect on cell density of Pseudomonas sp. BOT4 on day three each with OD600 value of 1,361 and 2,300. Nevertheless both nitrogen sources did not really give real effect on final weight of degraded oil, each with weight of 1,28 g dan 1,09 g
Analisis Cemaran Bakteri Coliform pada Makanan Tradisional Sotong Pangkong di Jalan Merdeka Kota Pontianak Berdasarkan Nilai Most Probably Number (MPN)

This research was observative and descriptive in nature,the data were tabulated by presenting table. The result showed that the sample of sotong pangkong was contaminated by coliform bacteria in which the MPN values was above the maximum limit, except for sample which had been roasted from seller IV (1100 MPN/gram. Meanwhile the lowest contamination on the sample before-roasted sample was recorded from seller II by 11 MPN/gram. The bacteria contamination was above the limit of bacterial contamination based on BPOM No. HK.00.06.1.52.4011 Year 2009 by <3/gram
Angka Lempeng Total Mikroba pada Minuman Teh di Kota Pontianak
