Abstract

Punti Kayu Natural Tourism Park is a conservation forest contained in Palembang with an area of 50 hectares. Conservation forest utilization as a natural tourism park has a fantastic tourism development potential. Considering this matter, it is necessary to research about vegetation analysis at Punti Kayu nature tourism park for tourism development at Punti Kayu Palembang. The purpose of this research is to know the composition and structure of tree vegetation at TWA Punti Kayu Palembang. The research was conducted from April to June 2017. The method used in this research is Simple Random Sampling with 63 plot total sample.The results of this study obtained 24 tree species consisting of 949 tree phases, 114 pole phases, 141 sappling phases, and 375 phases of seedlings.Tree phases was dominated by Pinus Spesies with total 750 trees (INP 212,65%), in the pole phase, sapplings phase and seedling phase were dominated by Talok with total 25 poles (INP 57,96%), 17 sapplings (INP 39.89%) and 60 seedlings (INP 29.51%), The level of diversity of tree species and seedlings included in the low category, the tree of 0.493 and the seedlings of 0.824. One characteristic of good vegetation is the high level of species diversity. according to Kristinawanti et al (2013) good tree vegetation will have a positive impact on increasing tourist visits The results of this research can be used to support tourism in Punti Kayu Nature Tourism Park because it can be used as a reference to assess the management of Punti Kayu Nature Tourism Park.

Abstract

Tissue culture techniques can be used for propagation of uniformaly large teak solomon seeds.The purpose of this research was knowing the effect of activated charcoal, the addition of benzyladenine (BA) and combination of BA with 6-furfurylaminopurine (kinetin) to the growth of shoots of solomon teak in vitro. The solomon teak explants used were singlestem cuttings from aseptic shoots obtained from in vitro cultures. This research was conducted in laboratory with complete randomized design with 3 replications. The experimental treatment was a single factor consisting of basic MS medium (Murashige and Skoog, 1962), with 6 treatments: MS without growth regulator (control), MS without growth regulator + 2 g/l activated charcoal, MS + 0,1 m/l BA , MS + 0,2 m/l BA, MS + 0,1 m/l BA + 0,1 m/l kinetin and MS + 0,2 m/l BA + 0,1 m/l kinetin. Observation on the number of books/ shoots, number of leaves/ shoots, shoot/ bud height and visual apperance of culture was taken at 8 weeks after planting. The data were analyzed for variety and continue the separation of the LSD at 5% level. The results showed that in general, all six treatments could be used for propagation of in vitro teak solomon (Tectona grandis Linn. f) and produced at least 6,22 books/ shoots every 8 weeks. The best media were MS medium + 0,1 m/l BA and MS + 0,1 m/1 BA + 0,1 m/l kinetin, because it able to produce 7,78 books/ shoots. The highest number of leaves was obtained at the treatment of MS + 0,1 m/l BA, while the average shoots/ shoots produced were not different for all.

Abstract

The weaver ant (Oecophylla smaragdina) is a eusocial insect, whose colonic life is highly dependent on the existence of trees. The existence of the weaver ant in natural habitat is now reduced due to the destruction of habitats caused by humans. To preserve the existence of weaver ant in nature needs to be studied bioecology as the purpose of this research is to know the characteristics of habitus and environment of weaver ants nest in Bandar Lampung. The research was conducted in June-October 2017 at the location of yard and plantation, using 50% sample from the sample population, from 20 districts in Bandar Lampung, 10 sub-districts were used as randomly selected research sites. The results showed as many as 15 types of plants used weaver ant for nesting. The most widely planted species of weaver ant is Mangifera sp. with characteristics of slippery surface habitus, sympodial branching, tree height of 3.9 to 11.5 m and an average canopy of> 65%, more nests found in yards (76%) far from urban areas, the percentage of the dominant nest toward the east , which is 41.8% of the total number of 86 nests.

Abstract

The purpose of this study was to decide whether the mixture of KNO3 and GA3 solutions was more effective than a single solution of KNO3 or GA3 in maintaining the freshness of cut flowers. The study was conducted at the Botanical Laboratory of the Department of Biology, Faculty of Mathematics and Natural Sciences, University of Lampung from November - December 2017. The research was carried out in a 2 x 3 factorial experiment with reason A was the GA3 solution with 3 concentration levels: 0%, 0.5%, and 1%. Factor B is KNO3 solution with 2 concentration levels: 0% and 5%. The limits in this study were fresh weight, dry weight, relative water content, and total dissolved carbohydrate content of gerbera cut flowers, qualitative limits were the level of reducing sugars. Measurements were made 7 days after soaking cut flowers in KNO3 or GA3 solutions, and a mixture of both. Homogeneity of variance and analysis of variance were determined at a significant level of 5%. Simple effect of KNO3 at each concentration level of GA3 decide by F test at 5% significance level. The results showed that GA3 with a concentration of 0.25% and 0.5% increased the fresh weight and dry weight of Gerbera cut flowers. KNO3 0.5% much reduced the relative water content of Gerbera cut flowers. The interaction between GA3 and KNO3 does not much effect all freshness of cut flowers. From the results of the study concluded that the single treatment of GA3 was more effective than the combination treatment of GA3 and KNO3 in maintaining the freshness of Gerbera cut flowers.

Abstract

Paraquat is one of the chemicals that contributes to increasing pollution Indonesia. The careless use of paraquat can increase production of ROS (Reactive Oxygen Species), resulting in damage to a wide range of vital organs and reproductive system disorders such as infertility. ROS in the body can be captured by antioxidants. Red Ginger contains high antioxidants because there are active phenolic compounds such as gingerol, shagaol, zingeron, ginggerdiol, and zingibren which are proven to protect body cells from damage caused by ROS. This study was aimed to test the effectiveness of red ginger extract (Zingiber officinale Roxb. Var. Rubrum) on the quantity and quality of sperm in male mice (Mus musculus L.) induced by paraquat dichloride.This research uses a completely randomized design and is divided into six treatment groups with each four replications: K1 as the control group (only given H2O); K2 (paraquat induced a dose of 20 mg/kg Body Weight (BW) without the administration of the test substances); K3; K4; K5 (paraquat induced a dose of 20 mg/kg Body Weight (BW) and was given a red ginger extract at a dose of consecutive succession 6 mg / ml, 12 mg / ml, 18 mg / ml) and K6 (Only given a test material the red ginger extract as much as 18 mg / ml). Paraquat was given 2 times a week for 21 days and the red ginger extract was given for 35 days. The results of analysis by One-way ANOVA followed LSD at 5% significance level showed the ethanolic extract of red ginger can increase the sperm count, motility, viability and Morphology sperm of mice induced by the paraquat diklorida.
