Now in these days infectious diseases seriously affect human health and sometimes these infections might become the cause of human mortality. Most of these infectious diseases are caused by bacteria, viruses, and fungi. Although large numbers of antibiotics are available increasing drug resistance in these microorganisms became a serious matter of concern in the scientific community. There is an urgent need for research on alternate natural products that can manage these pathogenic microorganisms without inducing any resistance. The purpose of this study was to determine the antibacterial activity of Robusta coffee (Coffea robusta L.) fruit peel extract against 5 human pathogenic bacteria i.e. Bacillus subtilis ATCC 6633, Staphylococcus aureus ATCC 25923, Escherichia coli ATCC 25922, Pseudomonas aeruginosa ATCC 27853, and Salmonella thypi NCTC 786. The sample was extracted using the maceration method with methanol as the solvent. The antibacterial activity of fruit peel extract was determined by using the agar diffusion method while the presence of active ingredients was determined by the using TLC-Bioautography assay performed using the mobile phase of n-hexane: ethyl acetate (1 : 3). The results of the study revealed significant antibacterial activity of coffee peel extract against E. coli and B. subtilis with an inhibition zone of 10.15 mm and 10.96 mm, respectively. Furthermore, results of the TLC-Bioautography revealed that the compounds at Rf 0.76 inhibit the growth of E. coli and the compounds at Rf 0.27 inhibit the growth of B. subtilis bacteria. These active spots were suspected to be flavonoid and phenolic compounds, respectively but further confirmation detail study is required in the future.

Malocclusion is an occlusion that deviates from the normal state, so it needs to be treated using an orthodontic device. The formation of new alveolar bone after obtaining an orthodontic force will be surrounded by osteoid bones are not stable enough (relapse). Robusta coffee (Coffea robusta) has flavonoids which can increase lymphocyte proliferation. The purpose of this study was to analyze the effect of robusta coffee on the number of lymphocyte cells in the tension area of marmot’s (Cavia cobaya) periodontal ligament which induced by mechanical orthodontic forces. This type of research is laboratory experimental with the Post Test Only Control Group Design. The average number of lymphocyte cells in group A = 0.75, B = 1.45, C = 1.26, D = 1.54. One-way Anova test results showed that the number of lymphocyte cells in all groups showed a significant difference (p <0.05). The results of the post hoc LSD test showed that group A had significant differences with group B and group D (p <0.05). While group C did not have a significant difference with group A (p> 0.05). The conclusion obtained is that the provision of robusta coffee brew for 2 weeks can increase the number of lymphocyte cells in the tension area of marmot’s (Cavia cobaya) periodontal ligament which induced by orthodontic mechanical forces compared to without robusta coffee brew.

Agroforestry systems, with products in the form of robusta coffee, can increase income and environmental sustainability. The research objective is to find out the robusta coffee marketing channel. Retrieval of data through interviews with actors or institutions involved, observation, and documentation studies. The data obtained were analyzed descriptively qualitatively about the structure, behavior, and market channels. The results of the study indicate that there are several marketing institutions, namely: farmers, collectors, wholesalers, retailers, and cooperatives. In addition, there are three channels of robusta coffee marketing, namely: (1) farmers to collectors, then wholesalers and retailers, (2) farmers to cooperatives, then retailers, and (3) farmers to cooperatives. The most efficient channel is the third channel, but most farmers choose to sell their coffee to the first channel. This is because of the closer distance to the collecting traders, the lending of money given to farmers by collecting traders, and the absence of special treatment for coffee sold. The market structure formed in coffee marketing is the oligopsonist market, where the price of coffee is determined by large traders. The capacity of cooperatives should be improved by the government in order to compete with collectors, wholesalers, and retailers.

Explaining patterns of diversity, and abundance across sites is a central aim of community ecology. Avian communities have been the focus of many studies on species diversity. To be able to explain patterns of waterbirds in wetlands of eastern Uganda, we conducted a rapid assessment in 48 wetlands (38 swamps, two rice paddies and eight lakes) using total counts. We examined waterbird assemblages in these wetlands in relation to wetland area, wetland type, water depth, water pH and the time of year/season. Statistical analysis were conducted using Genstat Version 8.1 (VSN Intl.2003, in which General Linear Mixed Models were used to examine the variations. In total, 9,410 birds from 64 species and 17 families were recorded. Species diversity and overall abundance varied significantly among wetland types and between seasons. Rice paddies were both more species-diverse than lakes and swamps. Wetland area had significant independent and positive effects on the waterbird community. In addition to explaining differences among wetland types in waterbird numbers, water depth had a positive effect on some aspects of the waterbird community with no significant effect of pH. These results imply that an interplay of factors is responsible for the pattern and structure of waterbird communities on wetlands in eastern Uganda.
