The Patembo Bridge is the longest bridge in North Sumatra, which is 860 meters long and and 6 meters wide, the bridge was built in 1995 and the completion was completed in 2008. Research method is survey method that is by direct observation and structured interview, with qualitative data analysis that is t- Paired test.Patembo Bridge development caused changes to the social and economic of coastal communities, especially the former pompong drivers, the coast in general bridge construction has a positive impact but for the former driver of pompong bridge has a negative impact. The construction of the bridge has a positive impact on the general public because with the bridges the traffic access becomes smooth and reducing the expenses, especially the cost of crossing the river, so it is very helpful to the community, inversely with the former people of the pompong driver. The bridge construction has a negative impact because after the bridge construction they have to switch livelihood which resulted in lower revenue. In essence, bridge development causes social change for pompong driver’s society that is negative change, such as attitude change, habits and behavior change, education, and economic change that is change of livelihood, decreasing income change.Keywords: Patembo Bridge Building, Social Change, Economic Change, Former Pompong Driver Community.

Abstract

Periphyton is a group of microorganisms that grow in some natural subsrates such as rock, wood, plants and aquatic animals. A research aims to understand the type and abundance of periphyton at smooth surface glass and rough surface glass in the Parit Belanda River has been carried out in March-April 2016. There are three station namely station 1 up stream, station 2 in the middle of stream, and station 3 at down stream. Sampling once/week for a 4 weeks period. The periphyton samples were brushed from the surface of glass substrate (8 cm x 3 cm). Type of periphyton was identified based on Bigg and Killroy (2000), Yunfang (1995) and Prescot (1974). Result shown that there are 36 types of phytoperiphyton are belonged to 4 classes, namely Bacillariophyceae (17 species), Chlorophyceae (10 species), Cyanophyceae (8 species) Rhodophyceae (1 spesies), whereas zooperiphyton are belonged to 5 classes, namely Monogononta (9 spesies), Euglenophyceae (3 spesies), Crustacea (1 spesies), Adenophprea (1 spesies) and Insecta (1 species). The abundance of phytoperiphyton attached in the smooth surfaced glass was 18,790-25,230 cells/cm2 and the zooperiphyton was 1,400-2,540 organisms/cm2. While the rough surfaced glass, it was 20,780-30,450 cell/cm2 and the zooperiphyton was 1,280-1,470 organisms/cm2. Based on the composition of periphyton, it can be concluded that the Parit Belanda River can be categorized as eutrophic.Keywords: Parit Belanda River, Periphyton, Glass Substrates
