Abstract

Bilimbi or cucumber tree often be used from almost all parts of the plant as a traditional medicine. In addition, people often use the leaves as a material for insects, especially to make flies away from food. The information of local knowledge that bilimbi leaves contains insect control. The purpose of this study was to control of subterranean termites attack using extract of bilimbi (Averrhoa bilimbi L) leaves.  The powder of the plant leaves was extracted using ethanol solution. The extracts were then prepared in different concentrations, namely 2%, 4%, and 6%. Paper discs with 25 mm diameter were immersed in the each of the concentration. The other treated paper discs used chlorpyrifos as positive treatment. Untreated paper discs were also prepared as control. In this study, only one of tests were applied, which were contact poison. The effectiveness of the extract was determined based on the termite mortality and weight loss of the paper discs. Results showed that treatment has a very significant effect on the value of mortality. Treatment of various concentrations of bilimbi leaf extract significantly different from the control and termiticide. Treatment of bilimbi leaf extract concentration and termitisida show 100% mortality whereas control only amounted to 23.64%. Keywords: Averrhoa bilimbi L, control, termite, extract, effectiveness

Abstract

Swiftlet bird (Collocalia fuciphaga) is a non-timber forest product that has high economic value. Swiftlet cultivation is ideally done in the lowlands and away from human settlements. Currently, a lot of swiftlet cultivation has been carried out in residential areas. As is the case in Wonomulyo District, Polewali Mandar Regency, West Sulawesi Province. The existence of this cultivation activity has a lot of impact on the socio-economic community. This study aims to determine public perceptions of swiftlet cultivation activities in Wonomulyo District, Polewali Mandar Regency, West Sulawesi Province. The research was conducted by interviewing 100 respondents who were around the swiftlet cultivation site. Data were analyzed descriptively quantitatively. The results showed an average attitude of 78% in the category of intercepting 75%–100%, which means that people feel very disturbed by Swiftlet bird cultivation.

Abstract

Coffee is one of the leading commodities in Mamasa Regency, West Sulawesi Province. Increasing coffee harvests have an impact on the amount of coffee husk waste produced. Coffee husk waste is usually only used as animal feed, fertilizer, and sometimes directly discarded, which has the potential to cause environmental pollution. This study aims to utilize coffee husk waste into products that have economic value by diversifying the processing, namely cascara tea with the addition of sappanwood extract. Cascara tea is a beverage product made from coffee husks (read cherry) as the basic ingredient that has a color and taste similar to tea. This study used a quantitative approach with experimental tests. Phytochemical analysis used the Analysis of Variance (ANOVA) method and continued with the Duncan Multiple Range Test (DMRT). The results showed that cascara tea is made by sorting and cleaning the coffee husk, drying, reducing the size, adding sappanwood powder, brewing and filtering to produce cascara tea. The results of the physicochemical tests to determine the quality of cascara tea products for each parameter were: moisture content of 10.8-11.7%, ash content of 6.9-7.3%, and pH value of 4.3-4.4. The organoleptic test results showed that sample P3 (ratio of 3 g coffee skin + 0.39 g sappan wood) was preferred by the panelists because it had a distinctive aromatic color, aroma and taste
