To show that banana inflorescence has effective adsorbent for the adsorption of dyes (congo red, remazol yellow, remazol black and methylene blue) from textile dyes waste and also to detrmine the optimum conditions of variety of pH (4-10), temperature (30°C-90°C), and contact time (15-105 minute) on the percentage adsorption capacity of banana inflorescence. Textile dyes waste and their degradation products such as aromatic amines are highhly carcinogenic. Adsorption-fluidization is a new technology for treatment of waste water containing different types of dyes. Adsorption-fluidization process is adopted for adsorption of dyes from the textile dyes waste using banana inflorescence in treated form and were analysed by Utraviolet-Visible Spectroscopy. The results showed that the optimum condition from adsorption process of Congo Red dye by banana inflorescence was reached at pH 5 (1.78%), temperature 60°C (1.51%) and 45 minute contact time (1.63%). While Remazol Yellow dye optimum at pH 9 (4.29%), temperature 50°C (4.65%) and 75 min (1.83%). Another dye, Methylene Blue showed the optimum condition at pH 9 (0.36%), temperature 40°C (0.22%) and 45 min contact time of adsorption (0.43%). The last, Remazol Black dye was reached at pH 5 (0.56%), temperature 40°C (0.56%) and 75 min contact time (0.56%).

Diabetes mellitus is a disease in humans characterized by an increase in blood glucose levels exceeds the normal limits. Cumin oil and olive oil is an alternative drug to a decrease in blood glucose levels for people with diabetes mellitus. Cumin oil and olive oil has several compounds that can lower blood glucose levels in excess. This study was conducted in January 2015 for 3 weeks in PUSVETMA Surabaya. Animals used in the study were female mice 2-3 months old with an average weight of 20-25 grams of a much as 30 individuals. At a dosage of dextrose 40% is 0.4 cc/ head/ day and the dosage of cumin oil and olive oil is 0.7 cc/ head/ day. This a study conducted of mice that had been induced dextrose 40% by using a sample of a much as 30 female mice. The results of statistical independent t-test, there was no difference or both of the test sample may lower blood glucose levels among female mice were treated with cumin oil and treated with olive oil. While the results of the data was tested using SPSS statistical Paired t-test showed that effectively lower blood glucose levels are olive oil, because there is a significant difference between before and after administration of olive oil after 7 days of dosing.

Dengue hemorrhagic fever (DHF) is a very dangerous disease, caused by Aedes aegypti mosquitoes. One alternative to controlling Aedes aegypti mosquitoes is to use insecticides. But it would be much better if the insecticides used are natural and environmentally friendly, one of them by using Tomato Leaf Extract (Solanum lycopersicum l.). Tomato leaves contain chemical compounds class Alkaloids and Saponins and can serve as anti larvacide. This research is a laboratory experiment which aims to find out the effect of tomato leaf extract (Solanum lycopersicum L.) activity on the death of III instar larvae of Aedes aegypti mosquito. the effectiveness of samples on Aedes aegypti mosquito larvae by treatment of variation of extract concentration 0.2%, 0.4%, 0.6%, 0.8%, 1% with repetition 2 times. In the results of research showed that the smallest concentration that can kill Aedes aegypti mosquito larvae is 0.6% at 16 hours and probit analysis showed that significance is 0,608 greater than intercept 0.003, it shows that the extract of tomato leaves affects the death of III instar larvae of Aedes aegypti mosquito.

Bunga sepatu (Hibiscus rosa-sinensis L.) merupakan tanaman semak kelompok Malvaceae yang berasal dari Asia Timur dan banyak dimanfaatkan sebagai pagar hidup maupun tanaman hias didaerah subtropis dan tropis. Bunga sepatu dulu banyak digunakankan sebagai pewarna alami untuk makanan. Bunga sepatu mengandung pigmen warna antosianin. Pemanfaatan antosianin telah banyak dilakukankan salah satunya pewarna produk makanan maupun minuman. Pewarna alami antosianin semakin banyak diminati karena dapat mengurangi penggunaan pewarna sintetik yang memiliki sifat toksik serta tidak ramah lingkungan. Tujuan penelitian ini adalah untuk mengetahui pemanfaatan ekstrak bunga sepatu (Hibiscus rosa-sinensis L.) sebagai pewarna alami pengganti eosin pada pengecatan diff quik. Sampel yang digunaakan untuk membuat sediaan sitologi berasal dari kerokan mukosa bukal. Bagian kelopak bunga sepatu yang diambil dan dikeringakan, kemudian diekstrak dengan pelarut etanol 96%. Dari hasil penelitian diketahui bahwa sediaan yang dapat terwarnai dengan baik pada konsentrasi ekstrak 0,5 gr/ml yang ditambahkan HCl 1% dengan waktu perendaman 30 menit. Serta pada konsntrasi ektrak 0,7 gr/ml dengan waktu perendaman 15 menit sel dapat terwarnai dengan cukup baik.

Telang flower (Clitorea ternatea L) is a type of vine that grows wild in rice fields and has been widely used as food coloring. Telang flowers contain several active compounds, which is anthocyanin gives a blue color. This research was conducted with the aim of knowing the telang flower extract as a natural dye to substitute methylenen blue in diff quik painting. The analysis samples used were oral mucosal ephithelial cells which were taken by scraping the oral mucosa using cytobrush. Dried and mashed telang flower was then dissolved with distilled water (1:5) to make an extracts before the trial process of the samples. The results showed that the epithelial cells stained with methylene blue were better than telang flower extract. The immersion time of 15 minutes gave different colors to the cell nucleus and cytoplasm compared to 2 minutes and 5 minutes of immersion.
