Abstract

The aim of this research is to analyse the effect of the number of buds per stem cutting on vegetative growth, especially from germination phase to budding phase of sugarcane GMP2 and GMP3 varieties. Research carried out in the garden practices of The State Polytechnic of Lampung, Rajabasa, Bandar Lampung in November 2014 to February 2015. The research method used a factorial randomized block design, consisting of two factors. The first factor was the sugarcane varieties, i.e. GMP2 and GMP3. The second factor was the amount of buds from stem cutting which consists of 4 levels: 1, 2, 3, and 4 buds per stem cutting. Based on the results of this research there was no interaction between variety and number of buds from stem cutting. Varieties affected on plant height, number of leaves, number of tillers, length of roots shoots (butters roots) and roots length rope (rope system roots). While the number of buds seeds mule had no effect on plant height, number of tillers, stem diameter, length of roots surface (superficial roots), and heavy roots.Keywords: number of buds, stem cutting, sugarcane varietiesPermalink: http://jurnal.polinela.ac.id/index.php/AIP/article/view/33

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

Abstract

Public rubber platation Indonesia reached 80% from the vast number of rubber Indonesia. But people rubber low quality, because the use of coagulant is not advice. The researc aims to use liquid smoke from midrib plam oil as an alternative coagulants formic acid to maintain the quality of crepe rubber. Dose of liquid smoke from midrib plam oil 4, 6, 8, 10, 12, and 14% given in each treatment 250 ml latex and will be tested pH, long clotting time, dry rubber content, plasticity retention index (PRI), leves of substance evaporates, until ash, and levels of dirt in acordance with the SNI 1903 : 2000. Tests conducted in te laboratory PTPN VII business Wwy Unit Berulu, Pesawara, Lampung. The results showed a dose of liquid smoke 4 – 12% crepe rubber produce with quality SIR 10, long clottng time dose treadment liquid smoke 14% but quality is only reached SIR 20 and dose treadment liquid smoke from midrib plam oil is best dosage 8% v/v.Keywords: crepe rubber, latex coagulant, liquid smoke, oil palm frondPermalink: http://jurnal.polinela.ac.id/index.php/AIP/article/view/35

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

Waste water that comes out of the milling process latex factory so many and has not been utilized, often becomes a problem for the environment if the handling is not optimal. This wastewater is known as latex serum. Latex serum can be used as an alternative coagulant because it has a low pH and containing metal ions. Low pH will lower the pH of the latex to the isoelectric point and cations of alkali metals will reduce electro kinetic potential latex, so latex becomes frozen. Research purposes to determine the length of time coagulation of latex, yield of coagulum and yield dry rubber. Research conducted at the Laboratory of Plant Production at Politeknik Negeri Lampung. The material used are latex serum and latex and other materials. The equipment used is the coagulation bath, digital pH meter, a wooden spatula, milling, stopwatch, and other analysis tools. The research tested in completely randomized design with one independent variable used is composed of coagulant doses: 0%, 4%, 8%, 12%, 16% and 20% v/v and replicated 3 times. The observation are pH of latex serum, pH oflatex, coagulation time, and yield dry rubber. The result showed that for pH of latex serum is 4.9, pH of latex is 6.22, the best doses to coagulation is 20% with time to coagulation 17 minute time, coagulum yield of 59.83 and dry rubber yield of 42.10.Keywords: coagulant, latex coagulation, latex serumPermalink: http://jurnal.polinela.ac.id/index.php/AIP/article/view/36

Abstract

Sugarcane (Saccharum officinarum L.) is a major source of commercial sugar production. Sugar is a commodity that is essential for the people of Indonesia both as a basic requirement as well as industrial raw material of food or beverage. Sugar demand is increasing with population growth and increasingly diverse array of foods. This study aims to determine the effect of mycorrhizal appropriate biological fertilizer for vegetative growth of sugarcane varieties of GMP and its interactions. Research carried out in the experimental garden of the State Polytechnic of Lampung, from July to December 2014. The method used was a randomized block design (RBD) factorial pattern, consisting of two treatment factors. The first factor was the rate of biofertilizers mycorrhizae which consisting of four levels, namely: M0 = 0 g of biofertilizers mycorrhizae per polybag, M1 = 10 g of biofertilizers mycorrhizae per polybag, M2 = 20 g of biofertilizers mycorrhizae per polybag and M3 = 30 g of biofertilizers mycorrhizae per polybag. The second factor was the varieties of sugarcane consisting of three varieties, namely: V1 = GMP1, V2 = GMP2 and V3 = GMP3. The results were analyzed using analysis of variance then continued with test least significant difference (LSD) 5%. The results showed that the effect on the variety of plant height and number of tillers. Mycorrhizal treatments and their interaction does not give effect to all parameters.Keywords: mycorrhizae, Saccharum officinarum L., vegetative growthPermalink: http://jurnal.polinela.ac.id/index.php/AIP/article/view/32
