Hubungan Hujan dan Limpasan Pada Sub DAS Kecil Penggunaan Lahan Hutan, Sawah, Kebun Campuran di DAS Kreo

Tendency of land use conversion is followed by maximum discharge of Kreo River, but unknown land use type what which can race improvement of runoff. Purpose of the research is study the relation of rainfall runoff at forest, rice field, and mixed garden. Research about rainfall runoff study is including research type of experiment for purpose of descriptive, through observation of rain data and water level at small watershed with one land use types that is forest, rice field, and mixed garden. Instrument of rain and water level attached at small watershed during the rains 2007.Data analysis comprises analysis of stream hydrograph, rain analysis, stream coefficient, and statistic analysis as well. Big the so small runoff value is more determined by rainfall amounts happened non land use type. Number of big rains at one land use will yield big runoff also, while the same rainfall amounts at some land use types will yield varying runoff follows land use type and condition of soil At small watershed (less than 200 ha), the relation of rainfall (P) with direct runoff (DRO) has very strong correlation (R2 bigger than 0.7). Relation between rain intensity (I) with DRO; I with peak discharge (Qp); duration of rain (DR) with DRO; DR with Qp indicated weak reaction (R2 less than 0.3). It indicated there were many factors (more than 70%) which influenced the above mentioned relations. Runoff coefficient value at forest was 0,3566, mix forest was 0,4227, rice field was 0,6661, and mixed garden was 0,4227. Land ability to permeate in the forest (65%) is bigger than mixed garden (57%) and rice field (33%)

IKLIM MIKRO DAN KEBUTUHAN RUANG TERBUKA HIJAU DI KOTA SEMARANG (The Micro Climate and The Need of Green Open Space for The City of Semarang)

ABSTRAK Salah satu darnpak perkembangan jumlah penduduk kota adalah terjadinya konversi lahan. Konversi ruang terbuka hijau (RTH) menjadi fasilitas bangunan menyebabkan terjadi pencemaran di kota. Berkurangnya RTH mengakibatkan terjadinya kenaikan temperatur lokal dalam kota. Keberadaan RTH memiliki manfaat cukup besar dalam peningkatan kualitas lingkungan hidup kota, seperti sebagai pengendali iklim mikro. Sebaran vegetasi perindang termasuk kategori jarang, terutama komposisi vegetasi rendah dan kerapatan pohon sangat jarang. Kondisi Iklim mikro secara keseluruhan termasuk kategori sebagian tidak nyaman, khususnya pada siang hari. Kondisi tersebut dipengaruhi oleh kurangnya vegetasi perindang di sepanjang jalan, sehingga kondisi iklim mikro menjadi panas dan kering. Keberadaan RTH di Semarang Tengah yang hanya seluas 6,77% perlu ditambah RTH seluas 14,02%. Diharapkan luas RTH sebesar 20,79% dari total luas wilayah, sehingga akan dapat memperbaiki iklim mikro di kawasan perkotaan. ABSTRACT One of the impact of people growth in town is land conversion. Green open space conversion become building facilities cause contamination in the city. Decreasing of green open space result local temperature increase in the city. Existence of green open space have big enough benefit of the quality of city environment, for example by controller of micro climate. The leafy vegetation spread include categories seldom, especially composition of low vegetation and closeness of tree very rare. Condition of micro climate as categorized 'a part unpleasant', specially in the day time. The condition influenced by decrease of  vegetation in alongside street, so that cause situation of micro climate hot and dry. Existence of green open space in Middle Semarang which only for the width of 6.77% require to be added green open space by 14.02%. So that expectedly wide of green open space equal to 20,79% from wide of total region, will be able to improvement of micro climate in urban area
