PERTUMBUHAN STEK PUCUK JABON PUTIH (Anthocephalus cadamba (Roxb.) Miq.) DENGAN PERENDAMAN MENGGUNAKAN EKSTRAK KECAMBAH KACANG HIJAU (Vigna radiata)
Get PDFWhite jabon (Anthocephalus cadamba (Roxb.) Miq) are plants with high economic value. It can be propagated vegetatively using its shoot cuttings. One of the way to enhance the growth of shoot cuttings by submersion in green bean sprout extract was expected to produce shoot cuttings with better growth. This study aimed to determine the submersion effect of white jabon (A. cadamba) shoot cuttings in green bean (Vigna sinensis) sprout extract. The Completely Randomized Design (CRD) consisted of 5 levels of treatment were used. The cuttings were submerged in extract concentrations of 0%, 25%, 50%, 75%, and 100%. The study parameters of number of roots and leaves, plant height, wet and dry weight were observed. The results showed that the concentration treatment with 75% green bean sprout extract produced 9,25±2,50 root strands, 5,75±0,50 leaves, plant height of 20,13±1,11 cm, wet weight of 12,39±3,62 g, and dry weight of 1,51±0,42 g
Deteksi Keberadaan Bakteri Staphylococcus di Udara Dalam Ruangan Pasar Tradisional Kota Pontianak
Get PDFBacteria belongs to the genus of Staphylococcus is pathogenic bacteria and its existence is an indicator of contaminated environment particularly in the air. The aim of this study is to detect the existence of bacteria belongs to Staphylococcus in the traditional market space of Pontianak city. The study was conducted in January - March 2018. Sampling was administered in 4 traditional markets of Pontianak City using volumetric air sampling along with a vacuum air pump YYP 550-12A1 with an air flow rate of 26 l / min for 6 minutes using Mannitol Salt Agar (MSA). The results showed that air bacteria member of the genus Staphylococcus found in all traditional markets in the city of Pontianak. The lowest number of bacteria belongs to the lowest Staphylococcus genus in the Flamboyan Market was 15 CFU/m3 and the highest was in Pasar Mawar 89 CFU/m3. The data indicates the air in the traditional market of Pontianak City has not fully fulfill the air health standards according to Sedyaningsih (2011), which is free of pathogenic bacteria 0 CFU/m3
Biomassa Dan Cadangan Karbon Di Kawasan Agroforestri Karet Tradisional Di Desa Nanga Pemubuh Kecamatan Sekadau Hulu Kabupaten Sekadau
Get PDFCarbon stock is carbon content strored either on the ground surface serving as plant biomass or in the ground functioning as soil organic matter. One of the area which can potentially absorb a large amount of carbon is traditional rubber agroforestry. This research aims at identifying biomass an carbon stock stored in the research site. The research was conducted for three mounths, starting from March to July 2017 in Nanga Pemubuh village. The identification of plant types was carried out in the biology lab of Mathematic and Natural Science Faculty, Tanjungpura University. To measure biomass and carbon stock, the research employed a transect method on tree stands with diameters more than 25 cm. Results revealed that the rate of density obtained in this research was about 6.5-46 trees/ha. After that, the biomass gathered was about 42.79 - 222.43 ton/ha and the stock ranged around 21.39 - 111.22 ton/ha
Pemanfaatan Lemna minor L. dan Hydrilla verticillata (L.f.) Royle untuk Memperbaiki Kualitas Air Limbah Laundry
Get PDFLemna minor and Hydrilla verticillata are types of water plants that have the potential to have the ability to process and improve the quality of polluted water. The purpose of this study is to determine the ability of Lemna minor and Hydrilla verticillata in improving the quality of laundry wastewater. The study used a completely randomized design (CRD) method with six treatments and three replications. The study was carried out on test media in the form of 5 liters of laundry wastewater with L. minor (L) 100 g, H. verticillata (H) 100 g, and combination treatment of both plants (L1H1, L1H2, L2H1) in weight L1H1 (50 g : 50 g), L1H2 (33 g : 67 g) and L2H1 (67 g : 33 g) for 14 days after acclimation for one week. The combination of L. minor and H. verticillata with a ratio of 1: 2 was able to reduce the highest Total Suspended Solid (TSS) and Total Dissolved Solid (TDS) of laundry wastewater with a decrease of 52.87% and 4.02% and increase dissolved oxygen (DO) of 7.13 mg/L. The highest decrease in chlorine occurred in L. minor and H. verticillata treatments with a ratio of 1:1 of 0.110 mg/L. All treatments of L. minor and H. verticillata both singly and in combination have not been able to reduce the phosphate content in laundry wastewater on day 14 of treatment

Angka Paling Mungkin (Most Probable Number/MPN) Coliform Sampel Kue Bingke Berendam di Pontianak
Get PDFBingke berendam cake is one of the traditional foods of Pontianak which is made from rice flour, eggs, sugar and coconut milk. Materials that are used such as sugar, milk and eggs are ingredients that are easily damaged and polluted by microbes. This study aimed to to find out the Most Probable Number (MPN) of coliform bacteria in bingke cakes. Taking bingke cake samples was done at five bingke cake shops in Pontianak city. Isolation of Coliform bacteria used the MPN method, with two stages, namely the estimator test tand the assertive test. Based on the results of this study, the five samples had MPN values ranging from 23 MPN/g to> 100 MPN/g. All samples had MPN values that exceed the threshold so that they did not meet the requirements for PERKA BPOM No. 16 of 2016, which is a 11 MPN/g
