Abstract

Peningkatan jumlah kendaraan bermotor berpotensi meningkatkan pencemaran udara terutama di jalan-jalan protokol. Untuk mengurangi semakin tingginya bahan pencemar yang dihasilkan kendaraan bermotor, perlu adanya pohon-pohon yang berfungsi sebagai penyerap dan penjerap bahan pencemar dan debu di udara yang dihasilkan kendaraan bermotor. Tujuan penelitain ini adalah mengetahui peranan tanaman di jalan-jalan protokol Kota Semarang dilihat dari kualitas dan kuantitasnya. Data mengenai jenis tanaman peneduh yang ada di jalan protokol Kota Semarang dihitung dengan metode line intercept. Hasil penelitian menunjukkan bahwa kualitas udara di Kota Semarang sudah cukup mengkhawatirkan, hal ini dipandang dari kadar CO yang relatif tinggi. Hasil penelitian terhadap jenis tanaman yang ada di jalan protokol Kota Semarang, dapat diketahui jenis tanaman yang ditanam di 5 jalan protokol Kota Semarang berjumlah 29 jenis. Jenis maupun jumlah tanaman yang ada pada masing-masing stasiun penelitian tidak berpengaruh positif terhadap kadar bahan pencemar udara yang ada. Simpulan dari penelitian ini ialah kualitas maupun kuantitas tanaman yang ada pada jalan-jalan protokol lokasi penelitian tidak berpengaruh positif terhadap kadar bahan pencemar udara yang ada. Hal ini dikarenakan jenis dan jumlah tanaman pada masing-masing jalan protokol tidak sesuai dengan tanaman peneduh yang mempunyai fungsi sebagai penjerap dan penyerap polutan udara.The increasing number of motor vehicles might potentially increase the air pollution in main roads. To reduce the increasing concentration of pollutants generated by motor vehicles, the trees are planted to absorb the pollutants and the dust in the air. The objective of the research was to understand the role of the plants along the main roads in Semarang City, from point of view of quality and quantity. Data on the kind and density of shedding plants along the main roads of Semarang City was collected using line intercept method. Result showed that the air quality of Semarang City has been worrying in terms of the high concentration of CO. There were 29 kinds of trees planted along 5 main roads in Semarang City. The kind and the number of plants in each station did not influence positively to the concentration of the air pollutants. It was concluded that the quality and the quantity of the plants along the study sites did not positively influence the concentration of the air pollutants. It was presumed that the kind and the number of plants along each ain road in Semarang was not appropriately functioning as the absorbants of the air pollutants.

Abstract

The coastal region is a dynamic area as a transition between the land and the sea. The ecological function of the coastal area is affected mainly by the structure and composition of vegetation factors. This study aims to analyze the vegetation stratification of terrestrial to marine ecosystems in the coastal area of Semarang City, Central Java Indonesia as an effort to manage a sustainable ecosystem. A striped path combined with nested plots were applied in this research. The plots were placed by systematic purposive sampling based on the homogeneity of vegetation found along with the topographic conditions of the research location. Analysis of qualitative data used by way of inventorying plants and identifying plants based on morphological characteristics that can be observed. Data analysis was performed based on the results of an inventory of the structure and composition of vegetation obtained including the index of diversity, evenness, and species richness. The results of plant identification found in the three locations recorded 51 plant species consisting of 29 families. The different types of vegetation in Taman Lele, Tapak, and Tirang Beach affect the diversity, richness, and evenness index of vegetation in all three locations. Therefore, it can be concluded that different environmental factors contribute to the vegetation stratification from the land to the sea. This is the first report on the Semarang coastal area vegetation stratification. The results can have a positive impact on the coastal area conservation strategy for sustainable management, as well as to be a media for environmental education purpose.
