Abstract

Dengue fever was one of the dangerous diseases due to it might cause death in a short time. It transmitted through its vectors, namely, Aedes aegypti and Aedes albopictus. Maya index is an indicator that used to identify a high-risk area or not as a breeding ground for Aedes sp. The purpose of this study was to determine the type of landfill which has the potential as a breeding ground for mosquitoes, to find out the larvae found in various landfill sites, and to know the Maya index status in Metro Timur Subdistrict which was carried out in November-December 2017. This research conducted by a direct survey of 100 residents' houses in East Metro. The results indicated that the type of controlled water reservoir that had the most potential as a breeding place for mosquitoes was a bathtub, while the type of water reservoir that was not controlled which had the potential as a place for mosquito breeding was a fish pond usage. There were 2 types of larvae found, namely, Aedes aegypti larvae with a percentage of 47.7% and Aedes albopictus larvae with a percentage of 52.3%. The Maya index status detected there, was a medium category, which obtained from the BRI combination and HRI category. Besides, it did not mean that the area has been free from dengue cases. The role of the community is still very much needed in eradicating landfills which has the potential as a breeding place for dengue mosquitoes vector.

Abstract

The residue of paraquat herbicides may cause human health problems. Paraquat causes the testosterone hormone to decline. Testosterone hormone affects aggressive and sexual behavior. It is caused by free radicals in the body. Free radicals can be non-reactive if in the body there are antioxidants. Red ginger could be used as an antioxidant because it has active phenolic compounds, such as arginine, gingerol, shogaol, zingerone, gingerdiol, and zingiber. Ginger could increase serum testosterone levels. The purpose of this research is to know the effect of red ginger ethanol extract on aggressiveness and libido of male mice induced by paraquat herbicide. This study used a Completely Randomized Design (RAL) consisting of six treatment groups with four replications each. Group P1 as control (aqua dest), P2 (paraquat at dose 20 mg/kg BM), P3, P4, P5 (paraquat with dose 20 mg/kg BM and red ginger extract at 200 mg/kg BM, 400 mg/kg BM, 600 mg/kg BM) and P6 (red ginger extract at 600mg/kg BM). Paraquat is given 2 times a week for 21 days and the red ginger extract is given daily for 35 days. The result of analysis with One-way ANOVA and continued BNT at 5% showed that giving of red ginger ethanol extract can increase aggressive behavior and libido of male mice induced paraquat herbicide.

Abstract

Cattleya was one of the most popular orchids by Indonesian. Constraints in cultivating Cattleya included the lack of water availability in an area, causing drought stress. Stress in drought in vitro can be simulated by adding Poly Ethylene Glycol 6000 and growth regulators in atonic form. The purpose was to determine the effect of atonic solution and PEG 6000 on the stomata index toward in vitro drought stress conditions. This study was carried out in a 3 x 3 factorial experiment. Factor A was an atonic solution with 3 concentration levels: 0 mL/L, 2 mL/L, and 3 mL/L. Factor B is PEG 6000 with 3 concentration levels: 0% b/v, 20% b/v, 25% b/v. The results showed that the higher the concentration of PEG 6000 and atonic concentrations caused a decrease in the stomata index of Cattleya orchid plantlets under drought stress conditions in vitro.

Abstract

Dendrobium sp. was a popular ornamental plant and has high economic value. One of many difficulties in the growth of orchids in Indonesia is low humidity and lack of water availability. Regulatory Substance Growth in the form of an atonic solution can increase the growth of orchid plants. The purpose of this study was to determine the effect of atonic solutions on orchid chlorophyll content in drought stress conditions. This study used a 3x3 factorial design. Factor A is the atonic solution with 3 levels of concentration: 0 mL/L, 2 mL/L, and 3 mL/L. Factor B is PEG 6000 with 3 concentration levels: 0% b/v, 20% b/v and 25% b/v. The parameters tested were chlorophyll a, b and total Dendrobium orchid plantlets. The results showed that atonic solution and PEG 6000 significantly affected the chlorophyll a, b and total content of chlorophyll. The higher concentration of the atonic solution, the more content of chlorophyll a, b and total plantlets of decreased in drought stress conditions in vitro.

Abstract

Jeruju had various chemical components. This study was conducted on the teratogenic test of jeruju leaf extract to determine abnormalities in fetal mice (Mus musculus L.). This study used a completely randomized design (CRD) method with 20 pregnant female mice divided into 4 groups: 1 group as a control and 3 groups treated with a dose of 3.75 mg/30grBB, 7.5 mg/30grBB, 15 mg/grBB, each with jeruju leaf extract consists of 5 repetitions. The results showed that the doses of 7.5 mg/30grBB and 15 mg/grBB significantly decreased fetal weight and length when compared with controls. This is suspected because there is an active substance in the jeruju leaf extract which is cytotoxic. Anatomically the administration of jeruju leaf extract does not cause abnormalities in the structure of the fetal spine of mice. This is due to the growing fetus taking priority from the many types of nutrients in the mother fluid so that the fetal bone can continue to grow and develop.

Abstract

The purpose of this study was to find out whether the combination of KNO3 and GA3 solutions were more effective than a single solution of KNO3 or GA3 in keeping the freshness of cut flowers. The research was conducted in Botanical Laboratory, Department of Biology, Faculty of Mathematics and Natural Sciences University of Lampung from November to December 2017. The experiment was conducted in 2 x 3 factorial experiment with factor A is GA3 solution with 3 concentration level: 0% w/v, 25% w/v, and 0.5% w/v. Factor B is KNO3 solution with 2 concentration levels: 0% w/v and 5% w/v. The parameters of this study were fresh weight, dry weight, relative water content, total chlorophyll content, total chlorophyll of leaves, and total carbohydrate content of rose cut flowers. Measurements were made 7 days after the immersion of cut flowers in KNO3 or GA3 solution, and mixed both. Homogeneity of variance and analysis of variance is determined at confidence level 5%. KNO3 simple effect at every level of GA3 concentration is determined by the F test at 5%. The results showed that there was no interaction between GA3 and KNO3 to fresh weight, dry weight, relative water content and chlorophyll content a, b and total white roses, but KNO3 reduced fresh weight of cut flowers by 48.15% and dry weight 58.60%. KNO3 increased the relative water content of white rose flowers by 6.85%. The results of the study concluded that the combination of GA3 and KNO3 is not effective to keep the freshness of white rose flowers cut.
