Abstract

The tropical climate in Indonesia supports the presence of many types of plants that have the potential to produce abundant vegetables and fruit, however the presence of fruit flies is an obstacle to fruit and vegetable productivity. Lemongrass and basil have been studied to contain several compounds that have the potential to control fruit fly attacks. This study aims to determine the effect of the ethanol extract of lemongrass pseudo stem (Cymbopogon citrates) and basil (Ocimum sanctum) leaves on the catch of Bactrocera fruit flies and to determine the concentration of the extract that has the highest number of catches. The method used in sampling was factorial randomized block design (RBD). The ethanol extract of the pseudo-lemongrass, the extract of basil leaves or the mixture of both extract (1:1) that was given at concentrations of 15%, 30% and 45% was dropped onto a piece of cotton and for then be put within a trap before placing on the tree. The cathes obtained from each extract at each concentration were observed if they show a significant difference in the number of fruit fly. Data were tested using analysis of variance (F test) at α = 0.05, followed by the Honest Significant Difference test (HSD). The results showed that the catch obtained from ethanol extract of lemongrass pseudo stem or from basil leaf ectract as well as  from their mixture had a significantly higher number of Bactrocera fruit flies than without using these extracts. The difference in extract concentration did not cause a difference in the ability to attract fruit flies. The conclusion of this study is that there is an effect of the  pseudo stem ethanol extract of lemongrass or basil leaf ectract as well as their mixture on the catch of Bactrocera fruit flies and these extract are recommended as non-synthetic pesticidesalternatives.

Abstract

White pomegranate (Punica granatum L.) is one of potential plant that can be use as an antimicrobial. The objective of this study was to determine antimicrobial activity of endophytic bacteria from white pomegranate (Punica granatum L.) in inhibiting the growth of pathogenic microbia (Staphylococcus aureus, Streptococcus viridans, Shigella dysentriae, Klebsiella pneumoniae and Fusarium sp. fungi). The stages of the research were isolation endophytic bacteria, antimicrobial assay, and characterization of potential endophytic bacterial. Endophytic bacterial were isolated from bark, leaves, flower, and fruit peel of white pomegranate taken from Gebang Baru, Mataram District. Antimicrobial assay was then performed using agar diffusion method, using supernatant of endophytic bacteria, water as negative control or ciprofloxacin as positive control. The potential isolates were characterized using Gram staining and biochemical test. The results showed that 2 endophytic bacterial isolates (DNX2 and BNG1) show strong activity against S. aureus, 3 endophytic bacterial isolates (BTG1, DNX11, and BNG1) show strong activity against S dysentriae, and 1 isolate KLBX11 shows medium activity against Fusarium sp. fungi. Those isolates are gram-possitive with bacill-shaped and produce spores. It can be concluded that it is possible to obtain potential endophytic bacterial from white pomegranate are potential as an alternative source for antimicrobial compounds.

Abstract

Fertilizer substitutes elements that have been used by plants. There are two available fertilizers, inorganic and organic fertilizers. Long-term use of inorganic fertilizers on a land negatively affects the crop and the soil fertility, hence, the organic one is a better choice. This study aims to determine the effect of liquid organic fertilizer of banana peels on the growth of red spinach and determine the best treatment for red spinach growth. This study used a Completely Randomized Design consisted of 2 factors (dosage of POC banana peel and length of fermentation time). Each has 4 levels, 3 replicates. The results of data analysis using ANOVA test show that the treatment of fermentation length and dosage of POC banana peel increase growth parameters of red spinach include plant height, leaf number, leaf area, fresh weight, and dry weight, while the interaction treatment of fermentation length and dosage of POC banana peel affects almost all growth parameters, except for the leaf area parameter that shows no interaction. DMRT (α 5%) test shows that the best combination treatment for plant height and fresh weight is a dosage of 8 ml POC of banana peel that have been fermented for 15 days, and the best treatment for leaf number and dry weight is a dosage of 8 ml POC of banana peel that have been fermented for 10 days.

Abstract

Bacillus thuringiensis is one of the bacteriae species that be able to kill insects. The latest research showed that the cell plasm of this bacteria contains crystalline protein with natural insectisides properties. Therefore the insecticidal effect of this species on insects which is decreasing cultivation plant production is interest to be examined. One of the insect species that are well-known causes of loss of farm production in fruit flies (Drosophila melanogaster). Therefore this research is designed to isolate, purify, and thenassess Bacillus thuringiensis toxicity against Drosophila melanogaster as animal treatment. Bacillus thuringiensis was successfully isolated from soil of  cows cage by using Lauria Bertani medium contain 0,25 M buffer solution Acetic, pH 6.8. The result shows that Bacillus thuringiensis isolate is a gram-positive bacteria. Position of endospore is located between the middle and the end of the cell (subterminal spore). Toxicity test was conducted by mixing 0.5 g/L, 1 g/L, 2 g/L, 4 g/L of pure Bacillus thuringiensis isolate into  Drosophila melanogaster medium. The treatments effect were monitored for 15 consecutive days. Toxicity test shows that the treatment has no significant effect on the treated animal mortality. This result shows that crystal-producing Bacillus thuringiensis strain isolated from cows cage soil do not have insecticidal properties for Drosophila melanogaster. It is concluded that Drosophila melanogaster is a non-target species of Bacillus thuringiensis.

Abstract

Cayenne pepper (Capsicum frustescens L.) is one of the commodities in Indonesia. The agricultural sector still relies on organic fertilizers to increase the productivity of Cayenne pepper plants. Excessive use of inorganic fertilizers will disrupt the balance of the amount of nutrients in the soil which results in plant metabolism. This study aims to determine the effect of liquid organic fertilizer from vegetable waste on the growth of cayenne pepper plants a completely randomized design (RAL) with 6 levels of treatment (0 ml, 20 ml, 40 ml, 60 ml, 70 ml and 80 ml), was used plants each with 4 repetitions and 4 fertilization times. The plant growth variables observed in this study includ plant height, number of leaves and wet weight. The data obtained were analyzed using one way Anova and further test using Duncan Multiple Range Test (DMRT) at a test level of 0.05. The results showed that the liquid organic fertilizer treatment of vegetable waste had a significant effect on the growth of cayenne pepper plants. Concentration of 80 ml of liquid organic fertilizer gave the best effect on plant height, number of leaves and wet weight among the concentrasi applied.
