Abstract

Used clothing is an item that is worn by humans to cover their bodies but has been worn previously by other people and is a potential source of skin disease due to the growth of yeast or mold. This research aims to determine the number of yeast molds on used clothes sold in the city of Mataram. This research is descriptive exploratory in nature, while the used clothing in the study consisted of 11 samples which came from used clothing sold at Bertais market and Karang Sukun market. Based on the research results, it was found that the number of yeast mold colonies on used clothes from the Bertais market in sample 1 was 624,175 cfu/ml, in sample 2 colonies was 6,583,460 cfu/ml, in sample 3 colonies it was found to be 5,413,860 cfu/ml, in sample 4 it was obtained the number of colonies was 776,450 cfu/ml, and in sample 5 the number of colonies was 7,336,260 cfu/ml. Contamination of the number of yeast mold colonies found in used clothing at the Bertais market was less than the yeast mold contamination of clothing at the Karang Sukung market with the number of colonies in sample 1 being 27,244,700 cfu/ml, the colony in sample 2 was 4,688,888 cfu/ml, the number of colonies in sample 1 was 27,244,700 cfu/ml, the colony in sample 2 was 4,688,888 cfu/ml, sample 3 obtained as much as 5,989,880 cfu/ml, colony sample 4 obtained as much as 8,807,140 cfu/ml, colony sample 5 obtained as much as 1,634,333 cfu/ml, and colony sample 6 obtained as much as 5,545,640 cfu/ml.

Abstract

The vegetation profile is a vertical and horizontal description as well as the structure and species composition of a vegetation which includes the dominance of canopy cover, species diversity, species dominance, species frequency, species density and undergrowth. This research aims to obtain an overview of the composition, vertical and horizontal structure of vegetation so as to provide information about tree dynamics and ecological conditions as well as to view tree architectural models. The method for collecting community profile data is carried out in each sample plot measuring 20x20 m with data requirements such as: trunk diameter at DBH height, tree height, tree height, canopy limit, and tree canopy projection. Based on data on tree height and diameter, it was concluded that the trees in the research plot area were trees of the past because they had a total height of between 20-54 meters with a trunk diameter of ±1.63 meters. the results of drawing architectural profiles of tree canopy projections horizontally and vertically so that we can see models of canopy closure and competition for sunlight in homogeneous forest tree communities consisting of the Agathis loranthifolia species. The results of the horizontal and vertical projection of the architectural profile of the tree canopy can be seen so that the model of canopy closure and competition for sunlight in a homogeneous forest tree community consisting of the Agathis loranthifolia species can be seen. The ecological function of the Agathis loranthifolia type is very good in maintaining the environment, related to groundwater storage which can reduce the impact of soil erosion rates. Certain tree architectural models influence the transformation of rainwater into stem flow rate, water through the canopy, infiltration and surface flow rate in an area which is related to the role of vegetation as disaster mitigation.
