This study was concentrated in three districts including Dhaka, Jashore, and Jhenaidah of Bangladesh where Imitation Jewelry has mostly clustered after the independence of the country. The sector was initiated in the period of Pakistan with a meager investment. The study was carried out with the view to achieving six objectives encompassing different issues of the sub-sector (environmental & technical, revenue-generating activities, non-revenue generating physical activities, environmental issues, certification, ecolabeling, branding, value chain development, etc.) and to assess the potential interventions for the Imitation Jewelry subsector of Bangladesh. The study deployed several tools and techniques for the collection of data.
The total population of the study was around 4500 in three districts who are members of the beneficiaries of PKSF through its partner NGOs like SUS, SNF, etc., and engaged in entrepreneurship and working in the subsector of Imitation Jewelry. The total number of entrepreneur surveys was 357 (27 from Jashore, 178 from Jhenaidah, and 151 from Dhaka) The sample of the study was fixed by the stratified sampling techniques assuming the population is normally distributed. For this study, the research matrix was prepared according to the objectives. Questionnaires were prepared to collect information from the primary research (by field survey/ household survey). On the other hand, Key Informants Information (KII) from the different Design Experts, Experts from Environmental Sciences, Marketing and Branding Experts, Entrepreneurs, Key people from the certification authority. Some of the questions were common to the key experts with the specialized issues of entrepreneurship, environmental, certifications, ecolabeling premium marketing, and branding issue to the respective key informants. Focus group discussions (FGD) were conducted for the collection of collective information from the respondents about their product quality, types, their problems, design and dices issues, and their suggestions for the development of the sector.
The questionnaire for the field survey information about academic qualifications, knowledge about environmental pollution, existing environmental conditions, the importance of modern technology for the production of befitting jewelry, training for better production, promotion of design, SWOT analysis of the sector, and required interventions to improve the overall condition of the sector was collected by the research team. After data collection, analysis was conducted by using the SPSS (IBM 22) software and the outputs of the analysis are in the respective chapter where pie charts, bar diagrams, cross-tabulations, correlations between different variables have been shown. In the Key Informant Interview (KIIs) the qualitative part of the study, five experts from each specialization like Fashion/Entrepreneurs, Environment /Climate Change, Branding /Marketing, and two key persons.Final Research Report on ‘Common Services activities, Technical & Environmen...

The study was designed to evaluate the antibacterial potential of three plants which are Andrographis paniculata, Durio zibethinus and Psidium guajava. Andrographis paniculata leaves (30mg/ml) and roots (30 mg/ml), Durio zibethinus wood bark (10mg/ml), and Psidium guajava leaves (15mg/ml) extract was obtained through the process called maceration, filtration, evaporation and the paste form was freshly reconstitute in dimethyl sulfoxide (DMSO) and tested against Staphylococcus aureus for Andrographis paniculata, Psidium guajava. Streptococcus agalactiae for Durio zibethinus and Psidium guajava and Escherichia coli for Durio zibethinus using Kirby Baur technique and the plates were incubated at 37 ºC. The zone of inhibition was measured after 24 hours and recorded in millimeters. The combination study was conducted using extract in combination with Penicillin G (6.25 µg/ ml) and erythromycin (15 µg/ ml; Andrographis paniculata) with the propotion of 1:1 in homogenous condition and incubated at 37 ºC for 24 hours. The zone of inhibition was measured and recorded. Mean and standard deviation was calculated. Andrographis paniculata do possesses some antibacterial activity against Staphylococcus aureus. Leaves (17.33 mm), roots (10.67 mm), erythromycin (24.00 mm), leaves and erythromycin (20.67 mm), roots and erythromycin (21.67 mm), leaves and roots (17.33 mm). Wood bark against Streptococcus agalactiae (14.67 mm), Penicillin G (14.00 mm), and combination (16.67 mm). Durio zibethinus showed antibacterial activity against Escherichia coli (11.00mm) and Penicillin G (13.33 mm). Psidium guajava leaves extract were having slightly higher activity than Penicillin G and in combination activity, leaves were having a slightly higher activity than Penicillin G.
