Abstract

Demands for environmental protection, especially water resources and in development planning, have shown an increase in recent years. However, the reference for protection of water resources has always been based on the level of pollution or changes in water quality. This paper discusses groundwater balance as an approach for housing development planning. This approach assumes that all water needs for residents in a settlement area and their activities are met from groundwater, and the used groundwater must be replaced by water absorption into the soil in the area. For this reason, comprehensive rainwater management is needed. The potential for rainwater in residential areas requires greater management efforts; in addition to controlling the runoff that occurs, the use of clean water is also necessary. The results of runoff analysis for housing in downstream and upstream areas showed a potential for runoff of approximately 105-115% from before the construction of housing until after it has been inhabited. Rainwater management by using infiltration wells as large as 0.82 m3/m2 and water balance of 13.3% is less effective in downstream areas with shallow groundwater levels, but more effective in reservoirs and for seepage of runoff water using a catchment pool of 28.26% or 1.74 m3/m2.Meanwhile, for housing in upstream areas with a low permeability coefficient, the infiltration pond is less effective for water infiltration into the soil by 0.032 m3/m2 or 0.0054%, with a higher level of groundwater than in the downstream housing areas, which can use more effective infiltration wells. Overall, the management of rainwater for clean water and drinking water has sufficient discharge and the quality of the pH of rainwater from the roofs of houses is still feasible, between 6.6 and 7.8. The perspective of people on the use of rainwater as clean water and drinking water is quite positive, at approximately 59-61%.Keywords: Groundwater balance, rainwater harvest, sustainable settlement

Abstract

Natural resource management is one of the primary needs of all living things, both for consumption and supporting other activities. Batu City, East Java Province, is a tourist area and a water catchment area that has the potential to be a source of ground water. However, the development of infrastructure as a espoused of tourist areas need serious undermining of the sustainability of the land water source. In 2001 the environmental carrying capacity ratio was 1.75 with a conditional safe status. In 2011 and 2015 the status of environmental carrying capacity has been exceeded with a ratio of 0.85 and 0.62. In 2017 there is a conditional safe status with an environmental carrying capacity ratio of 1.24.Keywords: Demand Water Resources, Ratio of carrying capacity, Supply water resources,

Abstract

Saat ini proporsi ruang terbuka hijau (RTH) semakin berkurang seiring peningkatan populasi dan kepadatan. Dalam pemenuhan pembangunan kawasan-kawasan pendukung sebagai akibat jumlah penduduk yang terus meningkat, alih fungsi lahan di Kota Malang tidak dapat dihindari. Undang-undang Nomor 26 Tahun 2007 Tentang Penataan Ruang menyebutkan bahwa proporsi RTH  minimal 30% dari luas kota.  Namun proporsi kebutuhan RTH suatu kota berbeda dengan kota lainnya. Tujuan penelitian ini adalah mengidentifikasi perubahan luasan RTH tahun 2000 hingga 2015 serta menghitung dan memodelkan luas RTH  yang dibutuhkan Kota Malang kedepannya secara dinamis untuk dapat mencukupi kebutuhan berdasarkan standar beraktivitas dan kebutuhan oksigen. Metode analisis yang digunakan untuk mengetahui perubahan RTH menggunakan peta hasil interpretasi citra satelit yang di overlay sehingga diketahui perubahan luasan RTH dan pengembangan model proyeksi kebutuhan RTH dilakukan dengan menggunakan pendekatan sistem dinamik. Temuan dari pembahasan menunjukan bahwa luas RTH Kota Malang dari tahun 2000 hingga 2015 terus mengalami penurunan  hingga 30% dan kebutuhan akan RTH terus meningkat setiap tahunnya berbanding lurus dengan penambahan jumlah penduduk sedangkan ketersediaan RTH terus berkurang. Skenario untuk memenuhi kebutuhan RTH Kota Malang dengan menekan laju imigrasi, menekan tingkat kelahiran, menekan pertumbuhan kawasan terbangun, pengurangan jumlah sepeda motor dan mobil, penambahan RTH privat dan publikKata Kunci: Kebutuhan Oksigen, Ruang Terbuka Hijau (RTH), Standar Beraktivitas
