Abstract

The purpose of this study was to determine the growth response of the cocoa seed to compost filter cake and nitrogen fertilizer application. This research has been carried out in State Polytechnic of Lampung teaching farm from September 2013 to March 2014 The method used was randomized block design (RBD) with factorial pattern consisting of two factors. The first factor is the compost filter cake, consisting of four levels, namely B0 = 0 g (control), B1 = 50 g, 100 g = B2, and B3 = 150 g per polybag. The second factor is the rate of nitrogen (Urea) fertilizer that consists of four levels, namely N0 = 0 g (control), N1 = 2.5 g, N2 =5.0 g and N3 = 7.5 g per polybag. The indicator used is cocoa seedlings (Theobroma cacao L.). Observations of plant height, leaf number, stem diameter, leaf width, root volume, shoot dry weight, root dry weight, and water content of the soil. Data were analyzed by analysis of variance with the level of accuracy of 5%, then if the calculated F value is greater than the F table, then followed by LSD test. The results showed the use of compost filter cake 150 g and 5.0 g of nitrogen fertilizer each per polybag give value stem diameter, root volume, stover dry weight, and root dry weight of cocoa seedlings higher than the other treatments.Keywords: filter cake compost, growing media, nitrogen fertilizer, Theobroma cacao L.Permalink: http://jurnal.polinela.ac.id/index.php/AIP/article/view/23

Abstract

Indonesia as the worlds second largest natural rubber producer, products derived predominantly (> 90%) in the form of crumb rubber. In the management of crumb rubber factoryshould basically be dynamic is to follow developments in technology and customer requirements, as well as efforts to increase competitiveness. To determine the performance of crumb rubber factory on the current and future compliance requirements have made observations on the management of crumb rubber factory. This research was conducted using a survey of crumb rubber factory in South Sumatera province. Determination respondents crumb rubber factory done intentionally (purposive sampling) the criteria for the location of the plant, production capacity, production processes, energy use, and production control. Survey activities conducted in crumb rubber factory located in Musi Banyuasin, Muara Enim and Banyuasin districts, as well as four factories located in the city of Palembang. Parameter observations include raw rubber material conditions, contamination control, energy aspects of processing, and the malodor control. The survey results indicate the selectivity in the purchase raw rubber material by the crumb rubber factories decreased due to competition tightly, it could have an impact on the risk of contamination problems in products SIR. Management of crumb rubber factories have sought to convert the use of fossil fuel resources  to materials that are environmentally friendly. Tata factory work generally show has been categorized as good, there is even a plant considered to be very good, fairly intensive use of labor inspectors in some parts of the process and the results are assessed effectively. Odor problems at the crumb rubber factories can be reduced by using good air circulation room and poring Deorub into blanket  before the drying.Keywords: consistency, contaminant, crumb rubber, energy, factory, quality, raw materialPermalink: http://jurnal.polinela.ac.id/index.php/AIP/article/view/24

Abstract

NPK fertilizer and organic fertilizer on the growth of oil palm seedlings in the main nursery aims to determine a single effect or interaction between the two on the growth of oil palm seedlings in the main nursery.  The experiment was conducted at the Polytechnic of Lampung from July 2013 to March 2014.  The study used Complete Randomized Design (CRD) factorial, which consists of two factors and each combination was repeated 3 times.  The first factor of NPK fertilizer with 3 levels, 100%, 50%, and 25% of the dose recommendation as much as 142 g.  The second factor is the dose of organic fertilizer (Organonitrofos) with 3 levels of treatment, without organic fertilizer, 18 g polybag-1, and 36 g polybag-1. Observation variables such as plant height, number of midrib, stem diameter, length of midrib, shoot dry weight, root dry weight and P total.  The results showed that NPK fertilizer at the age of 9 months to increase the length midrib, shoot dry weight and root dry weight. Effect of dosage of the best there is at 100%.  The combination of NPK fertilizer and organic fertilizer there is an interaction of the dry weight of the roots and the best interaction was achieved by treatment of 50% NPK fertilizer and organic fertilizer  36 g polybag-1.Keywords: NPK fertilizer, oil palm, organonitrofosPermalink: http://jurnal.polinela.ac.id/index.php/AIP/article/view/20

Abstract

Cocoa plants are plantation crops that have high economic value and stable. Cocoa prospects quite good because the market demand is very big commodity. The research was conducted in field trials, Lampung State Polytechnic, from  September 2014 up to February 2015. Experiments conducted with factorial randomized block design with 2 factors and any combination treatment was repeated three times. The first factor, namely the provision of oil palm fiber to the growing media consisting of 0% oil palm fiber and 100% soil, 25% oil palm fiber and 75% land, 50% oil palm fiber and 50% of the land. The second factor, namely the provision of liquid organic fertilizer of cow urine which consists of 0 ml of cow urine, cow urine of 40 ml, 80 ml of cow urine, cow urine and 120 ml. This study was conducted to determine the effect of oil palm fiber and cow urine, as well as the provision of fiber interactions palm and cow urine on the growth of cocoa seedlings. The results showed the provision of oil palm fiber 0% gives better results than the 25% and 50% in high-seed, stem diameter, number of leaves, dry weight and root length stover. Giving cow urine of 40 ml to 120 ml showed better results than without the provision of cow urine on seedling height, stem diameter, number of leaves, dry weight stover, and root length. In general, oil palm fiber giving no effect on the growth of cocoa seedlings and cow urine giving a dose of 40 ml to 120 ml to give effect to the growth of cocoa seedlings. There is interaction granting palm fiber and cow urine on a number of leaves and length of plant roots.Keywords: cocoa seed, cow urine, fiber palm oilPermalink: http://jurnal.polinela.ac.id/index.php/AIP/article/view/25

Abstract

Virgin Coconut Oil (VCO) is the coconut oil that is produced naturally without chemicals and heating process. Papain enzyme is a protease that is used in the fermentation of milk serves as a catalyst in the manufacture of the VCO. The main of the research is to determine the dose of enzyme papain that can produce the highest yield of VCO and determine the effect of papain enzyme dosage on the quality of the VCO. This research used a randomized block design (RBD) by using the enzyme papain treatment 0%, 0:03%, 0:06%, 0:09%, 0:12%, and 0:15% and it was repeated for three times. The result of the study treatment dose is 0.15%. The enzyme papain produces the highest yield of 31.53%. Based on the BSN about the quality standard ISO VCO No.7381: 2008 include moisture content, free fatty acids, color, and aroma of the VCO papain enzyme. And the result of the treatment did not affect the quality of the VCO.Keywords : fermentation, papain enzyme, VCOPermalink: http://jurnal.polinela.ac.id/index.php/AIP/article/view/21

Abstract

Growing medium influence plant growth and development. The purpose of this study was to determine the best growing medium used in the nursery of pepper (Piper nigrum L.). The experiment was conducted by using a randomized block design (RBD) with treatment: P0: subsoil, P1: subsoiland manure (2: 1), P2: subsoil and sand (2: 1), P3: subsoil, manure and sand (2: 1: 1), P4: topsoil, P5: topsoil and manure (2: 1), P6: top soil and sand (2: 1), P7: topsoil, manure and sand (2: 1:1). There are 8 treatment, 4 replicates of each treatment was repeated. Each experimental unit comprises 3 cuttings, cuttings planted each polybag, so there are 32 experimental units  with overall there are 96 polybags. Based on the results of the study there were significant differences among the medium on the growth observed variables: shoot height, number of leaves, shoot diameter, shoot dry weight and root dry weight. Subsoil + manure (2: 1), subsoil + manure + sand (2: 1: 1), topsoil, topsoil + manure (2: 1), topsoil + manure + sand (2: 1: 1) provide good growth on cuttings of pepper, so it can be used in the nursery cuttings pepper.Keywords :pepper cutting, planting medium, seedling growthPermalink: http://jurnal.polinela.ac.id/index.php/AIP/article/view/22
