Abstract

ABSTRACT: A Based on the Regulation of the State Minister for the Environment No. 12 of 2009, it is explained that rainwater is a source of water that can be used as a filler for groundwater and or used directly to overcome water shortages during the dry season and floods during the rainy season. The construction of a new building for the Rectorate of the University of Bangka Belitung resulted in a change in land use, which previously was a forest that was still overgrown with plants into a building to support lecture activities. This will have an impact on decreasing the quantity of water that seeps into the ground and increasing runoff. One of the water conservation technologies that can be used to utilize rainwater is rainwater harvesting. The existence of management and utilization of rainwater can reduce surface runoff discharge and continuous use of groundwater. Therefore, rainwater harvesting is carried out as an appropriate water conservation technology to be applied at the Rectorate Building of the University of Bangka Belitung which is expected to save groundwater use and reduce surface runoff discharge. The method used is the method of collecting and processing data. In the analysis of Rainwater Harvesting (RH), the calculation of RH capacity is calculated based on the Minister of Public Works Regulation concerning Implementation of Non-Pipeline Road Network SPAM Development No. 01/PRT/M2009. From the research results, it was found that the raw water requirement for the Rector Building at the University of Bangka Belitung was 2.275 m3/day with a PAH tank capacity of 76 m3 and the total cost of building a rainwater reservoir for the Rector Building at the University of Bangka Belitung was Rp. 147,453,000.00.. Keywords: Rainwater, Raw Water, Rainwater StorageABSTRAK: Berdasarkan Peraturan Menteri Negara Lingkungan Hidup No 12 tahun 2009, dijelaskan bahwa air hujan merupakan sumber air yang dapat dimanfaatkan sebagai pengisi air tanah dan atau dimanfaatkan secara langsung untuk mengatasi kekurangan air pada musim kemarau dan banjir pada musim penghujan. Adanya pembangunanan gedung baru Rektorat Universitas Bangka Belitung mengakibatkan berubahnya tata guna lahan, yang sebelumnya kawasan tersebut adalah hutan yang masih ditumbuhi tanaman menjadi gedung untuk menunjang aktivitas perkuliahan. Hal ini akan berdampak pada menurunnya kuantitas air yang meresap ke dalam tanah dan meningkatnya aliran permukaan. Salah satu teknologi konservasi air yang dapat dilakukan untuk memanfaatkan air hujan adalah pemanenan air hujan. Adanya penggelolaan dan pemanfaatan air hujan dapat menggurangi debit aliran permukaan dan penggunaan air tanah secara terus menerus. Oleh karena itu dilakukannya pemanenan air hujan sebagai teknologi konservasi air yang tepat guna untuk diaplikasikan di Gedung Rektorat Universitas Bangka Belitung yang diharapkan dapat menghemat penggunaan air tanah dan mengurangi debit limpasan aliran permukaan. Metode yang digunakan yaitu metode pengumpulan dan pengolahan data. Dalam analisis kapasitas Pemanenan Air Hujan (PAH), perhitungan kapasitas PAH dihitung berdasarkan Permen PU tentang Penyelenggaraan Pengembangan SPAM Bukan Jaringan Jalan Perpipaan No. 01/PRT/M2009. Dari hasil penelitian, didapatkan kebutuhan air baku pada Gedung Rektorat Universitas Bangka Belitung sebesar 2,275 m3/hari dengan kapasitas tangki PAH sebesar 76 m3serta total biaya pembangunan penampung air hujan Gedung Rektorat Universitas Bangka Belitung sebesar Rp 147.453.000,00.Kata kunci: Air Hujan, Air Baku, Penampungan Air Hujan

Abstract

Clay soil is a type of soil that has problems because it has high plasticity, a low carrying capacity, and is prone to settlement. This soil condition can be found in the Hanging Tramble, Pangkalpinang City. This study aims to determine the effect of FGD waste gypsum on clay soils, the maximum value of soil shear strength, and the minimum value of soil consolidation settlement. The stabilizing agent used in this study was Flue Gas Desulfurization ( FGD) waste gypsum with a mixture of 10%, 15%, and 20% FGD waste gypsum from the dry weight of the soil., for a total of 39 samples of the test object. Testing in this research uses Indonesian National Standards (SNI).The test results obtained the maximum value of the shear strength of the soil in the FGD waste variations of gypsum at 15%, which is 115.243 kN/m2, and in the 20% FGD gypsum waste mixture, the value of the shear strength of the soil decreased by 79.634 kN/m2. The minimum value for consolidation settlement was obtained from FGD waste variations (gypsum 20%), which is 0.683 cm. The minimum value obtained for consolidation settlement is influenced by the calcium content in the FGD waste gypsum, which can bind soil minerals so as to increase soil strength. It can be concluded that the maximum soil shear strength value occurs in the 15% FGD waste mixed sample variation gypsum, while the minimum soil consolidation settlement value is in the 20% mixed FGD waste mixture gypsum.
