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

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

Giberellic acid (GA3) is a natural and sintetic grower hormone for speeding up the germination process. The research objective is for knowing the soaking time effect, giberelin (GA3) concentration and the interaction of both factors toward germination and growth of the Robusta coffee seed. This research was carried out in a nursery garden of The State Polytechnic of Lampung, from June 2014 until July 2015. Research arranged by factorial used Randomized Completely Block Design (RCBD). First factor was Giberelin (GA3) concentration i.e. G0 (without GA3), G1 (Giberelin concentration 1000 mg.l-1), G2 (Giberelin concentration 1250 mg.l-1), and G3 (Giberelin concentration 1500 mg.l-1). The second factor was soaking time i.e. A1 (soaking until 12 hours), A2 (soaking until 16 hours), A3 (soaking until 20 hours), and A4 (soaking until 24 hours). The results showed the seed soaking with giberelin (GA3) could affect germinate power, germinated seed quantities, and dry weigh of shoot. There was interaction between giberelin (GA3) concentration and soaking time that could increase germinated seed quantities, leaves wide and dry weigh of shoot.Keywords: Robusta coffee seed, soaking time, giberelin (GA3)Permalink: http://jurnal.polinela.ac.id/index.php/AIP/article/view/31

Abstract

The process of roasting the coffee beans will produce a good quality of taste and aroma. To conduct this research activity in the roasting researchers used a minimalist roaster machine (mini roaster). This study was conducted to determine the effect of temperature and duration of roasting, and the interaction of temperature and long roasting on the quality of Robusta coffee.The experiment was conducted in analysis laboratory, plant laboratory, and THP State Polytechnic of Lampung in November 2014 to February 2015. The experiments were performed with a patterned factorial randomized block design with 2 factors and each treatment combination was repeated 3 times. The first factor is the temperature which consists of three levels i.e. 190 oC, 200 oC, and 210 oC. The second factor is roasting duration wich consist of three levels i.e. 10 minutes, 16 minutes and 22 minutes. The results showed that the temperature 190 oC was the best in the roasting. Roasting duration 10 minutes was the best in the roasting process. Temperatures above 190 oC and duration above 10 minutes will reduce the quality of the coffee. The combination of the best treatment in the process of roasting seen from the middle value in the variable water content, juice coffee and caffeine levels are long roasting temperature of 190 oC and 10 minutes. Based on advanced testing methods Tukey confidence level of 95%, no interaction by the temperature and duration of roasting the coffee extract and the water content, but shows the interaction of the ash content and the caffeine content.Keywords: quality of Robusta coffee, roasting duration, roasting temperaturePermalink: http://jurnal.polinela.ac.id/index.php/AIP/article/view/34
