Abstract

The aim of study to test the inhibitory solution of lidah merua (Sansevieria trifasciata) on amount of bacteri, protein content, and organoleptic characteristics (color, aroma, and, mucus) of broiler chickens meat (Gallus domesticus). Study was conducted in a completely randomized experimental design with 5 level solution of S. Trifasciata (0, 15, 30, 45, and 60 g/100 ml), each of treatment was 4 replication. Application have done by soaking 100 g broiler chickens meat in solution of S. Trifasciata for 30 minutes. The result of this study shown soaking broiler chickens meat in solution of S. Trifasciata significant (P<0,05) influence amount of bacteri, but not significant (P> 0.05) influence protein content, and organoleptic characteristics (color, aroma, and mucus). solution of S. Trifasciata concentrations 15 g/100 ml can be durable chicken brioler meat and not change protein content. But organoleptic characteristics color and aroma of broiler chickens meat which like panelists are the concentration 15 g/100 ml and mucus of broiler chickens meat which like panelists are the concentration 45 g/100 ml. Study conclude that soaking broiler chickens meat in solution of S. Trifasciata can be hamper amount of bacteri but not change protein content and organoleptic characteristics (color, aroma, and mucus) of broiler chickens meat. Keywords: Sansevieria trifasciata broiler chickens meat amount of bacteri protein content organoleptic

Abstract

The solvents of aloe (Aloe vera) are known to be used as an antibacterial. This study aims to prove the antibacterial activity in broiler chicken meat (Gallus domesticus), the variables were observed in this studythe number of bacteria, protein content and organoleptic properties of broiler meat soaked in a solvents ofaloe vera. Aloe vera is obtained from MIPA laboratory of blender, then dissolved in aquadest. This study wasconducted using a completely randomized experimental design consisting of 5 concentration of aloe vera (0,25, 30, 35, 40 g / 100ml) with 4 replications. The results showed that the concentration of aloe significanteffect (P<0.05) against the number of bacteria on broiler chicken meat. However, no significant effect (P>0.05) on protein content and organoleptic properties. Results of this study indicate that aloe vera solventsconcentration of 25 g / 100 ml can be used to preserve meat broiler without altering the protein contentand organoleptic properties. Keywords: broiler chicken meat, Aloe vera, bacteria, proteins, organoleptic

Abstract

ABSTRACT This study aims to menegetahui effect of leaf extracts of lime (Citrus aurantifolia) and extract lemongr ass (Cymbopogon nardus) on mortality of larvae of Aedes aegypti and A. aegypti. The design of this study used a sample of 500 larvae of A. aegypti who has reached the third instar, the test was divided into 2 groups, each group has the same concentration of test ie 0, 0,5, 1,0, 1.5, and 2,0 g / l. Each test group contained 25 larvae in the leaf extract solution of lime and lemongrass with replication performed 4 times. Based on the analysis of the effect of the leaf extract of citrus and lemon grass extracts and concentrations that meet the criteria in the ability to kill larvae were started at a concentration of 0, 0,5, 1,0, 1,5, and 2,0 g/l. Concentration of extract lime leaves and lemongrass extracts can kill mosquito larvae A. aegypti is the lime leaf extract concentration of 2,0 g / l with an average mortality of larvae as larvae 18,75. While the lemongrass extract concentrations that kill larvae more effectively is 2,0 g / l with an average mortality of larvae as larvae 16,25. T-test results showed that there was no significant difference (P> 0,05) between the leaf extract lemon with lemon grass extract against mosquito larvae mortality rate A. aegypti. Can be concluded that the leaf extract of lemon and lemongrass naymuk effect on mortality of larvae of A. aegypti. Lethal concentration 50 to extract lime leaves and lemongrass extracts respectively 1,57 and 1,59 g / l in water. Keywords: lime, lemon grass, A. aegypti, and mortality

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh pemberian ekstrak daun kecubung gunung (Brugmansia suaveolens) dan daun bintaro (Cerberra maghas) terhadap mortalitas larva nyamuk Anopheles sp. Sebanyak 1000 larva Anopheles sp tahap instar III dibagi menjadi 2 kelompok. Setiap kelompok mendapatkan perlakuan penambahan ekstrak daun sebesar 0, 1, 2, 3, dan 4 g/l. Masing-masing perlakuan menggunakan 25 larva uji dengan 4 kali pengulangan. Hasil uji aktivitas larvasida menunjukkan penambahan masing-masing ekstrak daun berpengaruh terhadap kematian larva nyamuk Anopheles sp. Aktivitas larvasida kedua kelompok semakin meningkat seiring dengan meningkatnya konsentrasi masing-masing ekstrak etanol daun. Semua perlakuan (1, 2, 3,4 g/L) kedua kelompok berbeda signifikan dengan kontrol (0 g/L), kecuali perlakuan ekstrak etanol daun kecubung gunung 1 g/L. Penamb ahan ekstrak etanol daun kecubung gunung dan daun bintaro pada konsentrasi 4 g/l rata-rata mampu membunuh larva berturut-turut sebanyak 21 dan 23 ekor. Penelitian ini menyimpulkan, bahwa ekstrak daun kecubung gunung dan ekstrak daun bintaro terbukti memiliki aktivitas larvasida terhadap larva nyamuk Anopheles sp, sehingga dapat digunakan masyarakat sekitar sebagai altenatif pengganti abate dalam memberantas larva nyamuk Aedes sp. Kata kunci : kecubung gunung, bintaro, Anopheles, dan larvasida.

Penelitian ini bertujuan untuk mengetahui aktivitas larvasida ekstrak daun bandotan (Ageratum conyzoides L.) dan bunga kenanga (Cananga odorata L.) pada larva nyamuk Aedes aegypti L. Sebanyak 500 ekor larva Aedes aegypti instar III dibagi menjadi 2 kelompok masing-masing 250 ekor. Kelompok pertama dibagi 5, masing-masing 25 ekor dimasukan ke dalam toples kaca dan disemprot ekstrak daun bandotan dengan konsentrasi 0, 1,0, 2,0, 3,0, dan 4,0 g/l. Kelompok kedua dibagi 5, masing-masing 25 ekor dimasukan ke dalam toples kaca dan disemprot ekstrak bungan kenanga dengan konsentrasi 0, 1,0, 2,0, 3,0, dan 4,0 g/l dalam air. Hasil penelitian memperlihatkan bahwa penyemprotan ekstrak daun bandotan dan ekstrak bunga kenanga berpegaruh signifikan (P<0,05) terhadap mortalitas larva nyamuk A aegypti. Mortalitas tertinggi larva nyamuk A aegypti diperoleh pada penyemprotan ekstrak daun bandotan dan ekstrak bunga kenanga 4,0 g/l dengan rata-rata mortalitas larva masing-masing 18 ekor dan 22 ekor larva. Hasil uji-t menunjukan bahwa mortalitas larva nyamuk A aegypti yang disemprot ekstrak bunga kenanga signifikan (P<0,0%) lebih tinggi dibandingkan mortalitas larva nyamuk A aegypti yang disemprot ekstrak daun bandotan. Dapat di simpulkan bahwa ekstrak daun bandotan dan bunga kenanga mempunyai aktivitas larvasida pada pada larva nyamuk Aedes aegypti L.

Abstract

This study aims to determine the effect of long storage of infused water lemon (Citrus limon) and cucumber (Cucumissativus L) on bacterial growth. Infused water will be stored for 0 hours, 12 hours, 24 hours, 36 hours, and 48 hours at room temperature. This research uses experimental method. The sample used in this research is infused water lemon and infused water cucumber. The research was conducted in Bacteriology laboratory of Surabaya Health Analyst Department in January 2017 - March 2017. Data analysis was done by observing bacterial colony using total plate number by comparing the two sample treatments. Then proceed with statistical test Independent sample t-test about colony calculation results on infused water lemon and infused water cucumber. The final results show that there is an increase in the number of bacteria in the infused water lemon and infused water cucumber every hour. This increase in the number of bacteria can occur due to improper infusion of water storage, and several factors affecting infused water damage. Keywords : Infused water lemon, infused water cucumber, storage duration, bacterial growth, Total Plate Number.
