Get PDFOcimum basilicum is one type of vegetables that can be consumed without having to be processed. Food consumed must have high nutritional value, clean and free of microbes. Coliform is one of the bacteria that can cause disease in humans. This study aims to determine the value of MPN on samples Ocimum basilicum leaves from warung lamongan in Pontianak and determine the existence of coliform bacteria on Ocimum basilicum leaf samples from warung lamongan in Pontianak. Detection of coliform bacteria using the MPN method. Detection of E. coli was carried out using EMBA media. The results showed that all samples had interval values between 210 MPN/g to > 1100 MPN/g. It showed that all samples excced the threshold determined by BPOM (2016), which was the maximum limit of coliform bacteria contamination in ready-toconsume vegetables was < 3 APM/g. The results of the identification of the bacterial genus coliform grouphad the members of genera Escherichia and Citrobacte

Pertumbuhan Tanaman Pakchoy (Brassica chinensis L.)pada Tanah Gambut dengan Pemberian Pupuk Kompos Kotoran Kambing
Get PDFThe cultivation of pakchoy (Brassica chinensis L.) on peat soil is challenged by a low soil fertility. The addition of goat manure compost is expected to increase the growth of pakchoy and the quality of the soil. The aim of the research were to identifying the infleunce of goat manure compost towards the growth of pakchoy (B. chinensis L.) on the peat soil. Additionally, it attempts to study the lowest concentrational of goat manure compost which can provide the best result for the growth of pakchoy (B. chinensis L.) on the peat soil.The research was conducted in a green house and a biology lab oot of the faculty of Mathematics and Natural Sciences, Tanjungpura University Pontianak. The analysis of soil, compost, leaf area and lime needs were carried out in an agronomy lab and chemical and soil fertility lab since October 2016 to March 2017. The research employed a completely randomised design (CRD) with a four-lewel treatment, including P0= 0 (control), P1= 62,5 gram, P2= 97,5 gram, and P3= 125 gram. The data in this research was then analysed through ANOVA test (Analysis of Variance). The result of ANOVA test which provides a clear influence was continued by a Duncan test at the level of 5%. The result showed that the provision of goat manure compost provides a clear effect toward all growth parameters. Moreover, the compost concentration on 62.5 gram is the lowest concentration which can provide the best result towards the plant height by 19.13 cm, number of leaves by 8.67 cm, total leaf area by 291.5 cm2, gross weight by 17.71 gram and dry weight by 1.22 gram

Pertumbuhan Anggrek Hitam (Coelogyne pandurata Lindl.) secara In Vitro Dengan Penambahan Ekstrak Tomat (Solanum lycopersicum L) Dan Benzyl Amino Purine (BAP)
Get PDFBlack orchid (Coelogyne pandurata Lindl.) Is an endemic germplasm Kalimantan. This orchid is in great demand because of the potential to have high economic value. Consequently, it is often overexploited, yet it has not been widely cultivated. This research aims to find out the effect of augmenting tomato extract and benzyl amino purine (BAP) in the growing of black orchid. This research started from January to March 2017 in Tissue Culture Laboratory Aloe Vera Center (AVC) Pontianak. This research used Completely Randomized Design (CRD) with 2 treatment factors and 3 repetition. The first factor was tomato extract (0%; 7,5%; 10%; 12,5%) and second factor was BAP (0 M; 10-6 M; 10-7 M). The results show that the single factor of tomato extract and BAP and the combination factor also did not have a real effect on the time shoots appear and the number of leaves. The interaction factor of tomato extract and BAP did not have a real effect on the number of shoots, but the single factor of tomato extract and BAP had a real effect on the number of shoots and single factor of BAP had a real effect on the number of leaves. The highest number of shoots was 3,33 in the treatment of tomato extract 7.5% and 1.33 in the treatment of BAP of 10-6 M. The highest number of leaves was 11.33 sheets in the treatment of tomato extract of 12,5% and the lowest number of leaves was in the treatment of tomato extract of 10% and BAP of 10-6 M with an average of 3,00 sheets
