To produce superior varieties, gene sources of high diversity are needed. The study was intended to reveal the diversity of qualitative and quantitative characters and the quality of Robusta coffee germplasm. The study conducted at Pakuwon Experimental Garden, Sukabumi Indonesia, used 14 accessions of Robusta coffee grown by a single stem system. The observed characteristics were qualitative and quantitative characteristics, caffeine content, and cup quality. The data were analyzed descriptively and grouped by cluster analysis using the PBSTAT program. The results revealed variations in the angle of insertion of primary branches, stipule shape, immature leaf color, leaf shape, leaf apex shape, young shoot color, mature leaf color, ripe fruit color, and fruit shape. The number of bunches/branch is the characteristic of the highest variation coefficient. Eleven accessions had cupping scores between 80 and 86 with a caffeine content of 1.39 - 2.06%. The accession B4-17-1 had the lowest yield, but its final cupping test score was the highest. At the dissimilarity coefficient of 0.25, 14 accessions of Robusta coffee are divided into two large groups, while at the dissimilarity coefficient of 0.15 they consist of four groups.

Coffee plants ( coffea sp ) is one type of biodiversity in Indonesia.Coffee is one of the most popular drink in the world.The high caffeine content in coffee has bad effect for health.One kind of coffee used in this research was Robusta, because caffeine content in robusta coffee is higher than arabica coffee, otherwise the type of arabica contain more sugar and volatile oil.To improve the quality of coffee then one of the process that need attention is on the process in the past harvest.One technology in the post harvested to fix tastes coffee is by fermentation using lactic acid bacteria ( BAL ).This research aimed to produce coffee with the caffeine levels lower by fermentation using BAL on yoghurt. Parameter this research include caffeine level, ph level, the water level, the ashes level and testing the like parameter of organolepticflavor, aroma, and colour of the coffee. The best experiment resulting from research coffee fermented with isolate yogurt for 48 hours, it had caffeine content of 1,09 % ,Ph of 4.73, water contentof 2.34, ashes content of 3.16, flavor parameter scored of 3.08, aroma parameter scored of 3, and color parameter scored of 2.09.

The objective of the present study is to evaluate the quality of the marketed and self collected samples of Plumbago zeylanica L. roots on the standardization parameters. This study is planned mainly to confirm changes with quality of drug. Now a day’s more demand of herbal drugs for disease treatment, lack of knowledge of proper methodology and availability are promoting the practices of adulteration and substitution. Thus, the standardization of the plant crude drugs is necessary to maintain their therapeutic efficacy. Comparative studies were carried out to evaluate the standards of P. zeylanica L. with emphasis on organoleptic evaluation, physicochemical and phytochemical analysis. Samples were procured from local market and self collected to determine the qualitative and quantitative variations. The result indicates that self collected sample showed significant results with comparison to marketed sample.

The quality of underwater images is an important problem for resource detection. However, the light scattering and plankton in water can impact the quality of underwater images. In this paper, a novel underwater image restoration based on non-convex, non-smooth variation and thermal exchange optimization is proposed. Firstly, the underwater dark channel prior is used to estimate the rough transmission map. Secondly, the rough transmission map is refined by the proposed adaptive non-convex non-smooth variation. Then, Thermal Exchange Optimization is applied to compensate for the red channel of underwater images. Finally, the restored image can be estimated via the image formation model. The results show that the proposed algorithm can output high-quality images, according to qualitative and quantitative analysis.

Coffee brews are one of the most popular drinks. They are consumed for caffeine and its stimulant properties. The study aimed to summarize data on the influence of various factors on caffeine content in brews prepared with different methods. The study was carried out using a literature review from 2010–2020. PubMed and Google Scholar databases were searched. Data on caffeine content was collected by analyzing the following factors: the influence of species, brewing time, water temperature, pressure, degree of roast, grinding degree, water type, water/coffee ratio as well as other factors (such as geographical origin). To sum up, converting caffeine content to 1 L of the brew, the highest content is that of brews prepared in an espresso machine (portafilter), with the amount of 7.5 g of a coffee blend (95% Robusta + 5% Arabica), and water (the volume of coffee brew was 25 mL) at a temperature of 92 °C and a pressure of 7 bar, but the highest content in one portion was detected in a brew of 50 g of Robusta coffee poured with 500 mL of cold water (25 °C) and boiled.

Although, the diverse activities and uses are one of the significant key factors to improve quality of streets, some places and shops in Mawlawi Street are disappeared or used by few number of people, while others are used by high number of people. Moreover, just some attractions and points of interest (POIs) are located in the Global Positioning System (GPS). This issues lead to lake of finding urban diversity in Mawlawi Street. This paper examines and find out the diversity of activities and uses that improves the quality of streets and makes successful streets in Sulaimaniya City Centre. It is also to identify POIs provided in GPS. The study employed a mix-methodology method. 330 questionnaire surveys, 20 semi-structured interview, and qualitative and quantitative observation, were conducted in Mawlawi Street. The results show that the diverse activities and choices are important key to make streets of Sulaimaniya City Center successful. There is also a need to define and insert many places on map for enhancing diversity. To secure the quality of the Street, this study suggests to improve the quality of goods and shops, provide night activities, and refresh some left places and shops along the Street.
