Pertumbuhan Bayam Merah (Amaranthus tricolor L.) yang diberi Pupuk Kompos Kotoran Kambing dengan Dekomposer Trichoderma harzianum
Get PDFRed spinach (Amaranthus tricolor L.) is one of vegetables which contains anthocyanin. This crop has not planted widely in West Kalimantan since this area has pits land. One of planting techniques to grow this crop on pits land is by adding fertilizer. The basic compost is goat manure. To fasten the composting process, Trichoderma harzianum was added as decomposer. The study was aiming at knowing the effect of goat manure compost with T. harzianum decomposer on the red spinach growth. The study used complete randomized design with 6 treatments. ANOVA result showed that adding compost fertilizer had significant effect on 6 treatment of red spinach (A. tricolor L.), such as plant height (F5,24 = 22,734, p = 0,0001), number of leaf (F5,24 = 17,266, p = 0,0001), wet weight stem (F5,24 = 11,717, p = 0,0001), dry weight stem (F5,24 = 11,770, p = 0,0001), wet weight root (F5,24 = 5,965, p = 0,0001), and dry weight root (F5,24 = 5,196, p = 0,002)
Cemaran Mikroba Berdasarkan Angka Lempeng Total dan Angka Paling Mungkin Koliform pada Minuman Air Tebu (Saccharum officinarum) di Kota Pontianak
Get PDFSugarcane juice is a drink that is quite favored by the people in Pontianak city. However, most sellers of sugarcane juice do not pay attention to hygiene in the use of equipment, storage and processing of sugarcane juice. This can be a cause of microbial contamination in sugarcane juice. The research aims to determine the microbial contamination based on the examination of Total Plate Count (TPC) and Most Probable Number (MPN) coliform in sugarcane (Saccharum officinarum) juice in Pontianak city. The samples in this research were sugarcane juice drinks without ice taken each 10% of the total sellers randomly in every district in the city of Pontianak. This is a descriptive study using TPC and MPN coliform methods, and supporting data such as temperature, humidity and hygiene factor. The results of the 30 samples tested showed the average TPC ranging from 2,4 x 104 to 1,7 x 105 CFU/ml and the avarage value of MPN coliform was >1100 CFU /ml. The values exceeding the threshold value of microbial contamination in juice drinks based on SNI 3719: 2014 in which for TPC the maximum is 1 x 104 CFU/ml, and for MPN coliform the maximum is 20 CFU/m

Get PDFCocoa (Theobroma cacao L.) is one of the plantation crops and major export commodity in Indonesia, but its development is widely still face barriers that their pests and diseases. Rotten fruit is the most dominant disease because it causes a large loss, one of the causes fruit rot disease is a fungal pathogen attack named Phytophthora palmivora (Butl.). This research aims to examine the ability of the fungus Trichoderma spp. insuppressing the growth of P. palmivora. Isolation and identification of fungi were calculated using direct planting method and dilution method, also the antagonists were tested in vitro. The results showed that three types of fungus Trichoderma found on cocoa plantations that Trichoderma sp. 1, Trichoderma harzianum, and Trichoderma viride. Based on the research results, T. viride most capable of inhibiting the growth of the fungus P. palmivora antagonist with highest percentage of 71.95%
Kualitas Kompos dari Kombinasi Eceng Gondok (Eichornia crassipes Mart. Solm) dan Pupuk Kandang Sapi dengan Inokulan Trichoderma harzianum L.
Get PDFWater Hyacinth (E. crassipes Mart. Solm) and cow manure can be used as organic fertilizer because they are organic materials which contain C, N, P, and K needed by plants. The composting process of E. crassipes and cow manure cannot be directly used as compost as they need a decomposer to accelerate thedecomposition of composting by adding T. harzianum. This research aims to find out the quality of compost from a combination of water hyacinth (E. crassipes) and cow manure with inoculant T. harzianum. The study was conducted for three months from March to May 2015. The method used was theCompletely Randomized Design (CRD) with Replacemant Series method consisting of five stage treatments which were repeated 3 times. The results indicated that the organic C content ranged between 31.29% and 35.42%, nitrogen content between 1.57% and 2.28%, the ratio of C / N ranged between 14.20 and 19.20, P2O5 ranged between 0.47% and 0.72%, K2O between 2.27% and 5, 57%, water content between 14.97% and 29.16%, pH between 6.4 and 6.8, the temperature between 270C and 280C, and humidity between 54.6% and 58.3%

Get PDFArabica coffee (Coffea arabica L.) is one of the commodities witha high economic value. The production of the arabica coffee plant (C. arabica L.) is influenced by seed dormancy. This research aimed to find out the effect of sulfuric acid (H2SO4) and gibberellin (GA3) in accelerating the dormancy breaking and germination of the seeds of arabica coffee (C. arabica L.). This research used a completely randomized design (CRD), which consisted of two factors. The first factor was the concentration of H2SO4consisting of 5 treatments, i.e. the concentration of 0% (A0), 5% (A1), 10% (A2), 15% (A3), and 20% (A4). The second factor was the concentration of 0 ppm GA3 0 ppm (B0), 20 ppm (B1), 40 ppm (B2), 60 ppm (B3), dan 80 ppm (B4). Each treatment was repeated 3 times, so 75 experimental units were obtained. Data were analyzed using ANOVA (Analysis of Variance) and a further test using the Duncan test. The research findings showed thatthe treatment of sulfuric acid (H2SO4) at concentration of 10% was the best concentration for accelerating the growth ofthe seed of arabica coffee (C. arabica L.) with a percentage of 57.18%. The combination of sulfuric acid (H2SO4) of 10% and gibberellin (GA3) of 40 ppm was the best concentration for the growth of germination of arabica coffee (C. arabica L.) with a percentage of 38%
PERTUMBUHAN STEK PUCUK TANAMAN JABON PUTIH (Anthocephalus cadamba (Roxb.) Miq.) SETELAH DIRENDAM DALAM URIN KAMBING (Capra aegagrus)
Get PDFJabon (Anthocephalus sp.) is native species of Indonesia and the cultivation of white jabon in west Kalimantan is still rare. One of the efforts to increase the production of jabon is through vegetative propagation shoot cutting. Propagation through shoot cutting often fails, in which the roots cannot grow. One of the ways of overcoming such failure is by providing exogenous growth regulator, namely, goat urine. This research aimed to find out the effect of the concentration of goat urine (Capra aegagrus) and soaking time on the growth of the shoot cuttings of white jabon. This research used a completely randomized factorial design (CRD) i.e. the factor of concentration (A) consisting of 4 levels of 0%, 6%, 8%, 10%, 12% and the factor of soaking time (B) consisting of four levels, i.e. 0 min, 5 minutes, 10 minutes and 15 minutes. The treatment was repeated three times. The research findings indicated that adding goat urine concentration of 12% and 15 minutes soaking time generated the average root number of 29 pieces, the plant height of 20.33 cm, thewet weight of 16.33 grams and the dry weight of 3.46 grams, and the average number of leaves of 9 pieces, which were obtained from the treatment of a concentration of 10% and a soaking time of 15 minutes

Get PDFThis research aimed to find out the types of plants, benefits parts of plant organs, and processing methods used for making natural flavor. The research was carried out on the Jangkang Tanjung Dayak community in Ribau Village and the Malay community in Sungai Kosak Village, Sanggau Regency. The method used in this research was interviews with the respondents being determined through snowball sampling. Quantitative analysis was also performed by calculating the frequency of citation, percentage of habitat, and parts of the plants used as natural flavor by the communities of the two villages. The research found 7 species of plants used as natural flavor by the Jangkang Tanjung Dayak community in Ribau Village and 9 species of plants by the Malay community of in Sungai Kosak Village. The leaves were the mots commonly used parts of the two villages with a percentage of 100%. The habitat from which the plants were mostly found was in the forest and the garden. The processing method depended on the parts and types of plant used. The plants used as natural flavor had the highest citation frequency value which reached 100% of the two villages; and the lowest value in the Jangkang Tanjung Dayak community was 40% and in the Malay 25%
