Item Aplikasi Pupuk Npk Terhadap Pertumbuhan Kakao (Theobroma cacao L.) Yang Ditanam Diantara Kelapa Sawit(2013-03-06) Marajahan M, Yudika; Islan. Khoiri; Khoiri,M. AmrulCocoa (Theobroma cacao L.) is a plant commonly grown in tropical countries. One place that has shade is under oil palm plantations. the use of compound fertilizers is also very good to do. Compound fertilizer is a fertilizer that contains more than one element(N, P, and K). To reduce the cost of fertilizer, compound fertilizer is often used as an alternative as a single-use fertilizer. This research was conducted to determine the effect of NPK fertilizer to cocoa (Theobroma cacao L.) planted among several stands of oil palm plantation. The design used Completely Randomized Design (CRD) non factorial consisting of one factor, namely NPK fertilizers, the treatment was repeated 4 times, so the total number of plants used are 20 cocoa crop. The dosage was as follows: N0 = 0 g / plant, N1 = 10 g / plant, N2 = 20 g / plant, N3 = 30 g / plant and N4 = 40 g / plant. Based on the study conducted we found that the NPK fertilizer applied on the seed plants in several doses gives a real influence on the parameters of plant's height and girth, but not significantly different from the parameters of the number of leaves, root dry weight and leaf area. NPK fertilizer at a dose of 30 g / plant showed better results compared to no fertilizer NPK, giving 10 g / NPK plant, giving 20 g / NPK fertilizer plant and the provision of 40 g / NPK plants.Item Pemberian Berbagai Dosis Abu Boiler Pada Pembibitan Kelapa Sawit (Elaeis guineensis jacq) di Pembibitan Utama (Main nursery)(2013-01-10) Astianto, Ardi; Ardian; Khoiri,M. AmrulThis study aimed to determine the effect of giving the boiler ash on the growth of oil palm seedlings. This research was conducted at the Experimental Farm of the Faculty of Agriculture, University of Riau, Rimbo panjang Village, Kampar regency for 4 months, starting from February 2012 to May 2012. The design used was completely randomized design (CRD) non factorial with 3 replications. As each of these factors is A0 (Without giving boiler ash), A1 (14 g / polybag boiler ash), A2 (19 g / polybag boiler ash), A3 (24 g / polybag boiler ash), A4 (29 g / polybag boiler ash). Then proceed with the trial of Duncan's New Multiple Range Test (DNMRT) at the level of 5%. Parameters observed increase plant height (cm), bulb diameter increment (cm), the number of leaves (pieces), plant dry weight (g) and root volume (ml). Based on the study conducted found that the increase in boiler ash dose given to oil palm plantations showed a significant effect on plant height increment, diameter increment hump, the number of leaves, plant dry weight and did not significantly affect root volume parameters. From this study that gives the best effect at a dose of boiler ash 29 g / polybag.Item Pengaruh Dosis Kompos Ampas Tahu Terhadap Pertumbuhan Bibit Kakao (Theobroma cacao, L)(2013-07-11) Mulyadi; Islan; Khoiri,M. AmrulGrowth of cocoa seedlings to a maximum of one of them with the required nutrient availability in the soil. Utilization of tofu waste into compost is a waste of effort to change the negative perceptions of the environment to be beneficial to plants. This study aims to get a dose of compost tofu is best for the growth and development of the cocoa seedlings. Studies have been conducted in experimental field of the Faculty of Agriculture, University Village Rimbo Riau Kampar Regency Long District Mine Riau province for 6 months from March to September 2012. This research was conducted using completely randomized design (CRD) consisting of 7 treatments and 3 replications, each re-treatment at 3 times so it gets 21 experimental units. Parameters measured were seedling height increment (cm), increase the number of leaves, stem diameter increment (cm), root volume, and plant dry weight ratio of the root crown. Used statistical analysis using analysis of variance and tested further by Duncan's test New Multiple Range Test (DNMRT) at the level of 5%. Based on the research that has been done dosing compost tofu 250 g / polybag showed the best results on the High parameter Seeds, stem diameter, root volume and plant dry weight, so to get a good growth of cocoa seedlings can use tofu waste compost dose 250 g / polybag.Item Pertumbuhan Bibit Karet (Hevea brasiliensis muell erg) Klon Unggul Penghasil Lateks-Kayu Pada Medium Yang Menggunakan Kompos Sampah Kota(2013-06-25) Purba, Hotni Mutiara; Sampoerno; Sampoerno; Khoiri,M. AmrulOptimal increase in rubber production should start with the selection of superior clones, use of quality seeds and good maintenance. This study aimed to determine the effect of dose on the growth of municipal waste compost seedling clones of rubber tree latex-rubber seedling growth and getting better. Research carried out for 4 months starting from October 2012 to January 2013 in UPT (Technical Implementation Unit), Experimental Farm Faculty of Agriculture, University of Riau Pekanbaru. Research conducted experiments using a completely randomized design (CRD) which are arranged in factorial consisting of two factors: The first factor is the dose that consists of compost composting A1 = 30 g / polybag, composting A2 = 40 g / polybag, A3 composting = 50 g / polybag. Factor II is a rubber seed clones producing latex-timber comprising IRR K1 = 5, K2 = IRR 118. The data obtained were statistically analyzed using analysis of variance and Duncan's test further with the New Multiple Range Test (DNMRT) at the level of 5%. Parameters measured were seedling height (cm), number of leaves (pieces), trunk circumference (cm), seedling dry weight, root crown ratio, and seed quality index. The results showed that the combination treatment of compost 50 g / polybag (20 tons / ha) in clones of IRR 5 that can increase seedling height, number of leaves, stem circumference, seedling dry weight, crown root ratio and seed quality index.
