AbstractCholesterol is a natural substance that has physical properties similar to fat but has the formula steroids. Cholesterol belongs to the non-hydrolyzed lipid group and is the main sterol in body tissues. When cholesterol levels increase, it can cause blockages in blood vessels. Several studies have explained that one of the compounds that can reduce cholesterol is flavonoid compounds, one of the plants containing flavonoid compounds is guava leaf (Syzygium aqueum (Burm.f.) Alston). The purpose of this study was to determine the activity and percent reduction in cholesterol levels and the EC50 value of the ethanol extract of guava leaves (Syzygium aqueum (Burm.f.) Alston) in vitro using UV-Vis spectrophotometry with a wavelength of 665 nm. Anticholesterol activity analysis was carried out using Lieberman-Burchard reagent with a test solution series of 150; 300; 450; 600; and 750 ppm. The results showed that the greater the concentration, the lower the absorbance produced and the higher the percent reduction in cholesterol levels. At a concentration of 750 ppm cholesterol decreased by 58.74%. And the obtained EC50 value of 462 ppm, which means at that concentration the ethanol extract of guava leaves (Syzygium aqueum (Burm.f.) Alston) can reduce 50% of the initial cholesterol.Keywords:Cholesterol, Guava leaf, In Vitro, Spectrophotometry UV-Vis, Syzygium aqueum (Burm.f.)Alston. AbstrakKolesterol merupakan suatu zat alami yang memiliki sifat fisik hampir sama dengan lemak tetapi memiliki rumus steroida. Kolesterol adalah sterol utama yang ada pada jaringan tubuh dan termasuk dalam golongan lipid yang tidak terhidrolisis. Apabila kadar kolesterol mengalami kenaikan, dapat menyebabkan penyumbatan pada pembuluh darah. Dari beberapa penelitian dijelaskan bahwa salah satu senyawa yang dapat menurunkan kolesterol adalah flavonoid, salah satu tanaman yang mengandung senyawa flavonoid adalah daun jambu air (Syzygium aqueum (Burm.f.)Alston). Tujuan dari penelitian ini adalah untuk mengetahui aktivitas dan persen penurunan kadar kolesterol serta nilai EC50 dari ekstrak etanol daun jambu air (Syzygium aqueum (Burm.f.)Alston) secara in vitro menggunakan spektrofotometri UV-Vis dengan panjang gelombang 665 nm. Analisis aktivitas antikolesterol dilakukan dengan menggunakan pereaksi Lieberman-Burchard dengan seri larutan sampeli 150; 300; 450; 600; dan 750 ppm. Hasil penelitian menunjukkan semakin besar konsentrasi, absorbansi yang dihasilkan adalah semakin rendah dan persen penurunan kadar kolesterolnya semakin tinggi. Pada konsentrasi 750 ppm terjadi penurunan kolesterol sebesar 58,74%. Dan diperoleh nilai EC50 sebesar 462 ppm yang artinya pada konsentrasi tersebut ekstrak etanol daun jambu air (Syzygium aqueum (Burm.f.)Alston) dapat menurunkan 50% dari kolesterol awal.Kata kunci: Daun jambu air;Kolesterol;In Vitro;Spektrofotometri UV-Vis;Syzygium aqueum (Burm.f.)Alston

In Toulouse, around 1850, a controversy about the structure of the Pyrenees pitted observatory director Frederic Petit against geology professor Alexandre Leymerie. The object of the debate was an assumption formulated by Petit: that the inside of the Pyrenees was practically hollow. This proposal was based on work that Petit initiated in order to determine the latitude of Toulouse. The debates, which took place within the Toulouse Academy of Science and also in local newspapers, illustrate the organization of disciplinary spaces in the nineteenth century. Petit defended his research method based on calculation; the geologist's perspective was from the field. The emergence of the less mathematical science of geology came up against nineteenth-century astronomical practices, centered on calculation. Dissected by calculation or by visual observation, the mountain was an object of controversy from the perspective of distinct scientific practices.

Guava leaf tea of Psidium guajava Linnaeus is commonly used as a medicine against gastroenteritis and child diarrhea by those who cannot afford or do not have access to antibiotics. This study screened the antimicrobial effect of essential oils and methanol, hexane, ethyl acetate extracts from guava leaves. The extracts were tested against diarrhea-causing bacteria: Staphylococcus aureus, Salmonella spp. and Escherichia coli. Strains that were screened included isolates from seabob shrimp, Xiphopenaeus kroyeri (Heller) and laboratory-type strains. Of the bacteria tested, Staphylococcus aureus strains were most inhibited by the extracts. The methanol extract showed greatest bacterial inhibition. No statistically significant differences were observed between the tested extract concentrations and their effect. The essential oil extract showed inhibitory activity against S. aureus and Salmonella spp. The strains isolated from the shrimp showed some resistance to commercially available antibiotics. These data support the use of guava leaf-made medicines in diarrhea cases where access to commercial antibiotics is restricted. In conclusion, guava leaf extracts and essential oil are very active against S. aureus, thus making up important potential sources of new antimicrobial compounds.

Guava leaves contain quercetin which can inhibit the growth of Propionibacterium acne. Thus, guava leaves have the potential to be anti-acne. Based on the benefits of guava leaves, it is necessary to formulate the ethanol extract of guava leaves in cream preparation and its characterization as well as to know the rate of releasing active substances. Preparation and standardization of guava leaf simplicia was carried out. After that, maceration, standardization and phytochemical screening of guava leaf ethanol extract were done. Positive extracts containing flavonoids were formulated into cream preparation. The concentration of stearic acid as emulgator of 14% and 18% was optimized. The formula was tested for physical and chemical properties such as organoleptic, spreadability, adhesion, viscosity and pH. The optimum formula was characterized using Franz diffusion test to determine the release of the active substance. The results showed that concentration of stearic acid as emulgator influenced the physical and chemical properties of the cream. Based on the results of this study it could be concluded that the optimum formula was stearic acid concentration of 14% with the release active substances for 3 hours of 2,5882 mg.

Natural dyes extracted from Cassia fistula and onion peels are used to dye wool that is pretreated with chitosan by using tannic acid as a mordant. The effect of the mordant concentration on the color strength (K/S) is discussed. The results obtained indicated that K/S increases after treatment with chitosan. It is also noticed that K/S increases with an increasing concentration of chitosan. K/S also increases with an increase of mordant concentration until 4% and then decreases. The effect of the dye bath pH, dyeing temperature and dyeing time are also studied. The K/S and dye uptake exhibit high values. Good fastness properties of the dyed fabric are achieved. The antimicrobial activity of chitosan-treated wool fabric is tested in accordance to diffusion agents. Test organisms, such as Escherichia coli, Bacillus subitilus Pseudomons aeruginosa and Staphylococcus aureus are used and the results indicate that the samples treated with a lower concentration of chitosan exhibit a smaller inhibition zone.

Subang Crystal Guava farmer groups have problems in the management and maintenance of plants that are still carried out by way of going down outside the Operating System Procedure (SOP) provided by the Subang Agriculture Service, especially in the management of disease prevention or plant pests and harvesting of Crystal Guava fruit . This makes the process of checking yields take a long time if it has to be adjusted to the SOP provisions. One alternative solution that aims to provide direction and treatment to farmers in managing guava crystals is to apply informatics technology in the form of an application model built for disease identification on Android-based guava leaves. This application uses the camera facilities on mobile phones to take photos of guava leaf samples. The research method used is a software development method (Enterprise Unified Process) whose stages include Construction, Transition, and Production. Java as a programming language, and Android Studio Tools as the editor. Application Identification of diseases on the guava leaves that were built after the trial can be used by the Crystal Guava Farmers in the Subang farmer group as a tool to determine the disease in the guava plants so that a method is obtained to treat the guava plants with a yield that is harvested expected to be optimal.

Fish is kinds of food that easy to spoil. High protein content in fish makes the food is a good medium for microorganisms. People commonly buy fish for consumption, however, not all fish are consumed at the same time. Fishes were stored in freezer for several days or preserved with additional chemical preservation. The use of organic preservatives have no harm. This paper discussed guava (Psidium guajava L) leave as natural fish preservation. The objectives were to analyze the potency of the leaves as a natural preservation for mackerel fish (Rastrelliger sp.). Fime parameters used to determine the fish quality as follows : gills, eye, texture, odour and mucilage. The treatments were leaf methanolic extract with doses 0, 20, 40, 60 and 80%. Data were taken on from 1 to 5 days after storage. The results showed that (i) Fish quality was decline and start to depraved at 2 day storage, especially at control treatment (0% extract). Treatment at doses 60 and 80%, the fish quality were still relatively good over 3 days storage. Even though the fish samples have been starting spoilage, those fishes were still available to be consumed. At the same time, with the other treatment, the fish samples have been spoiled and no more available to be consumed. However, at 5th day of storage, all samples at all treatments were spoiled. Overall results, it can be concluded that extract of guava leaves can be has as fish preservativedosage

Environmental science and management is often the most discussed subject nowadays all over the world. In a number of countries, presently plenty of harms are associated with the effluent by industrial due to growing industrialization; this issue should be considered at large scale. Textile sector is one of the leading areas, which uses a high amount of chemicals and creating environmental pollution. Textile wet processing sector uses a lot of chemicals, surfactants and synthetic dyes, hence produce a large amount of wastewater having a high concentration of chemicals. This research is an effort to investigate the amount of residue remained in liquor after bleaching and reuses this liquor by adding a few chemicals according to the requirement. Afterward, the comparison was made between the bleached sample with fresh liquor and bleached sample with reused liquor. It was observed that bleaching with reused liquor shows good results though these results are insignificantly less than fresh bleaching liquor. On the other hand, fortunately, the color yield of dyed fabric bleached with reused liquor is higher than fresh liquor.
