Abstract

ABSTRAKFiltrasi bantaran sungai digunakan untuk memperbaiki kualitas air sungai sebagai sumber air bersih. Penelitian ini bertujuan untuk menganalisis karakteristik geologi dan hidrogeologi tapak filtrasi tebing sungai, mengukur penurunan muka air tanah sumur akibat pemompaan pada bantaran sungai, memperkirakan jari-jari pengaruh sumur sebagai parameter utama dalam perencanaan sumur produksi dengan filtrasi tebing sungai. Lokasi uji pemompaan yang terletak di bantaran sungai Cihideung sesuai untuk pembangunan sumur filtrasi tebing sungai dengan memiliki nilai konduktivitas hidraulik berkisar 2,5 – 4,32 m/hari. Jari-jari pengaruh sumur sekitar 45 m. Metode Thiem dan aplikasi Akuifer Test Versi 4.2 memberikan hasil yang baik dalam menduga nilai konduktivitas hidraulik pada lokasi penelitian. Nilai jari-jari pengaruh sumur paling tepat diperoleh dengan menggunakan metode ketakseimbangan dan MLU 2.5.Kata kunci: filtrasi bantaran sungai, uji pemompaan, konduktivitas hidraulik, jari-jari pengaruh sumurABSTRACTRiverbank filtration is used to improve river water quality as drinking water source. This study aims to analyze geological, and hydrogeological characteristic of riverbank filtration site, measuring drawdown characteristic of pumping well on the riverbank, determine well radius of influence as the key parameter on the design of production well with riverbank filtration. Pumping site located at the riverbank of Cihideung river is suitable as riverbank filtration site with hidraulic condutivity 2.5 – 4.32 m/day. Well radius of influence is around 45 m. Thiem method and Akuifer test 4.2 are giving satisfied result on estimating value of hidraulic conductivity. Best value of well radius of influence given by MLU 2.5 and non equilibrium method.Keywords: riverbank filtration, pumping test, hydraulic conductivity, radius of influence

Abstract

Environment quality has been worsening year by year; and building’s sector contributes 66% of fossil fuels pollution’s sources. The technique in building constructions needs to changing in order to increase environmental friendly manner. Indigenous people, such as the Inner Baduy community, from longstanding experience have developed systems as their local wisdoms adapting to its environment and houses in a sustainable manner. The objective of this study is to emphasize the importance of traditional knowledge in terms of providing low input energy buildings and settlement. A reconstruction of the Inner Baduy house has been drawn as a documentation of an Indonesian traditional house building in a tropical humid climate. The reconstruction is presented in a form of a technical drawings such as plan, view and section  drawing by using SkecthUp computer program. Baduy local wisdom of community is significant  in houseing structure development process. Indications by all the structure materials is taken from local sources such as rumbia roof and bamboo’s wall are taken from leuweung lembur and bantaran sungai. Development system’s local wisdom also very economic and efficient using pre-fabrication system. Key  words:  ecological design, environmental friendly, traditional building, sustainable construction
