Abstract

Mimosa pudica leaves contain of metabolites such as tannin, flavonoid and alkaloid which have the anthelmintic effects. This effect would be expected to minimalize the infection of parasitic worm Ascaridia galli in chicken. The research aim was to determine the effectivity of ethanol extract from mimosa leaves to A. galli worm in vitro. Mimosa leaves were extracted using maceration process. Worm samples were grouped randomly, consist of the positive control (Piperazine 1%), negative control (CMC Na 0.5%) and the treatment groups (10%, 20% and 50% of extract concentration). Mortality and paralysis data from the worm samples were collected and analyzed using Kruskal Wallis and Mann Whitney Test. The phytochemical analysis showed that mimosa leaves extract contains all the secondary metabolite which can cause paralysis and mortality of A. galli. The 50% concentration of mimosa leaves extract can cause paralysis in 90 minutes equal with the positive control. The mortality time achieved by positive control, 50%, 20% and 10% of ethanol extract of mimosa leaves sequentially as follows 120, 270, 645 and 780 minutes. In conclusion, 50% mimosa leaves extract concentration have the best effect of anthelmintic, the paralysis effect equal with Piperazine but the mortality time is still slower than Piperazine.

Abstract

Hydroponic drip irrigation technique is a system of giving water by dripping directly on the area around plant roots. Nutrients commonly used in hydroponic systems are AB Mix which is made from synthetic chemicals. It is expected that these nutrients can be replace with liquid organic fertilizers (POC), but the use of POCs has resulted in poor plant growth due to the lack of plant absorption of POCs. Liquid organic fertilizer absorption can be increased by using planting media with high CEC (cation exchange capacity) such as zeolites. This study was conducted to determine the effect of zeolite on POC absorption on the growth of mustard greens (Brassica juncea L.) grown hydroponically with drip irrigation technique and to determine the optimum concentration. The study used the RAL method (Completely Randomized Design) with a ratio of zeolite and husk charcoal, namely 100% husk charcoal as control (P0), zeolite 15% (P1), 30% (P2), and 45% (P3). Twenty plants used in each treatment. The results showed that P3 had the most optimal growth compared to other treatments, both in terms of the average leaf area of ​​162.88 cm2, as well as fresh weight of 17.24 grams, and dry weight of 1.08 grams.

Abstract

In order to maintain the continuity of the ecotourism area and several infrastructures built in the coast of sekotong, we need to conduct a further research about the bernacles diversity that has a potential to caused damage to the waterfront-city building made with wood, rocks and tiles. This study aims to see the bernacles diversity in three different ecosystems such as mangrove, seagrasess and coral reef ecosystem with three different natural growth medium made with wood, rocks and tiles. The result demonstrated that there's only two species of bernacles found growth and living in all of the growth medium in three different ecosystems. These species were belongs to the genera of amphibalanus and terctralitella The tetraclitella genus only found grow and live on a wooden medium in the mangrove and seagrasses medium. Meanwhile the amphibalanus found mostly in every growth medium om each ecosystems. Thus, made the amphibalanus as dominant genus with the density of 1644,4 individual/m2. Whereas the tertraclitella density were only 22,22 individu/m2.

Abstract

Staphylococcus aureus is one of the pathogenic bacteria that causes pyogenic infections that lead into several diseases such as ulcers, acne, throat infections, food poisoning, and pneumonia. Papaya leaves (Carica papaya L.) contains flavonoid, tannins, alkaloids, and saponins that has functioned as an antibacterial. The aim of this research to test the effectiveness extracts of 96% ethanol, ethyl acetate, n-hexane, and infusion of aquadest of papaya leaves, as well as to see the effect of the concentration of the best extracts using the sumuran method. The results were carried out by measuring the diameter of the clear zone formed in each extract. Ethyl acetate extract of papaya leaves had the highest activity with a clear zone diameter 21.5 mm, followed by aquadest, n-hexane, and 96% ethanol infusion extract with each clear zone has diameter 15.8 mm, 13.0 mm, and 0.0 mm. The higher the concentration of the extract, the higher the inhibitory power, this can be seen from the results of the measurement of the clear zone of papaya leaf ethyl acetate extract with a concentration range of 80%, 60%, 40%, and 20%, respectively 21.5 mm, 13, 0mm, 8.5mm, and 0.0 mm. This shows that papaya leaves (Carica papaya L.) can be used as an antibacterial against Staphylococcus aureus.

Abstract

Cilok is a boiled snack made from starch with or without a mixture of minced meat, has a savory and chewy taste. Cilok is one of the favorite snacks in Indonesia. Most cilok sellers sell their cilok right on the side of the main road for hours. This allows cilok that are sold to be contaminated with various bacteria. This study aims to calculate the Total Plate Count (TPC) of bacteria and to identify Salmonella sp. in cilok and its sauce in Selaparang District, Mataram City. This study used quantitative method in the form of calculating the TPC of the bacteria and qualitative method in the form of sample isolation on selective media, sugar, and biochemical tests. The results of this study showed that the TPC of the bacteria from the cilok sellers samples number 1 to 8 were 1,2x102, 1x101, 1x101, 2x101, 1,2x102, 1,5x102, 3,9x101, and 3,5x102 cfu/g respectively. Meanwhile, the TPC of the bacteria from sellers' sauce samples number 1 to 8 were 2x102, 1,8x103, 1x101, 1x101, 1,5x101, 7,9x103, 1,7x105 and 1,7x103 cfu/mL, and there was no contamination of Salmonella sp. on cilok nor its sauce samples. All the cilok samples that has been examined had TPC bacterial value that did not exceed the standards set by SNI 7388-2009, so they were still safe for consumption. Meanwhile, one out of eight sauce samples had a bacterial TPC value that exceeded the standard, making it not safe for consumption.
