Abstract

Taman atap merupakan salah satu teknologi tiruan dari kondisi penerapan Ruang Terbuka Hijau (RTH) dalam pengendalian sumber daya untuk mengurangi volume limpasan air hujan. Taman atap sebagai penyeimbang ekosistem kota dapat meningkatkan ketersediaan ruang terbuka hijau sebagai daerah resapan air, ditengah berkurangnya daerah resapan pada hunian perkotaan. Taman atap menangkap air hujan secara langsung yang berakibat pengurangan volume air limpasan hujan yang akan mengalir ke sungai dan laut. Tujuan dari penelitian ini adalah untuk mengetahui berapa jumlah limpasan yang dihasilkan setelah melalui taman atap sebagai area resapan tiruan. Diharapkan dari penelitian ini akan menghasilkan pembuktian bahwa instalasi taman atap dapat mengurangi volume limpasan air hujan.Penelitian direncanakan secara experimental pada atap hunian perkotaan dengan kemiringan atap 30-35°. Pembuatan instalasi taman hijau dimodifikasi dan disesuaikan dengan struktur atap yang ada, dengan pertimbangan penggunaan material yang ringan dan aman bagi atap. Dilakukan pengukuran berapa jumlah volume limpasan yang dihasilkan secara aktual. Dari analisa didapatkan bahwa sejumlah sekitar 68,42% dari total volume limpasan hujan yang dapat terinfiltrasi bila keseluruhan atap di daerah penelitian tertutup seluruhnya oleh taman hijau. Perhitungan berat dari 1 buah instalasi box planter adalah 42,73 N/mm2 (MPa), sehingga untuk maksimum instalasi box planter yang dapat diaplikasikan berjumlah 13 buah.

Abstract

Cikapundung River Restoration lies in a river border with a steep sloping slope and waves to the west - eastwhich is formed from the flow of the river cikapundung. Generally, the soil structure of the CikapundungRiver Basin slope is residual ground, corrosion stone and colluvial deposition,which caused vulnerable tolandslides. It was also separate and able to keep water. Therefore, shear strength is weak, especially if wateris saturated. In this case landslides always occur when it rains. In general, this is due to high rainfall with acertain duration, thus causing the stability of the slope is disrupted. Another cause is the non-functioningdrainage system because it is covered by some material from the slopes submitted by water. Therefore, thewater rubs the slope.

Abstract

The imbalance between supply and demand of water needed to do assessment of water availability and needs good water for balance. Development of the region in certain areas led to increased water demand due to population growth. Watershed Development seeks to manage the relationship hydrology to optimize use of natural resources for conservation, productivity, and poverty reduction. To achieve this requires a coordinated management of the various resources in the watershed, including forests, farms, agricultural land, surface and underground water through the hydrologic processes (Kerr, 2007). Cisadane River is the largest contributor to the water source for the residents of Tangerang City and surrounding areas. With the increasing development of all aspects of life, as the impact of population growth and development in an area, it also increases the needs and demands of water services that require water allocation management. Planning for Watershed Management Cisadane divided into three parts, the first watershed upstream side based on the functions of conservation managed to maintain the environmental conditions of the watershed that is not degraded, which among other things can be indicated on the condition of vegetation cover land watersheds, water quality, the ability to store water (discharge), and rainfall. Both DAS middle part is based on the function of the utilization of river water that managed to provide benefits to the social and economic interests, which among other things can be indicated from water quantity, water quality, the ability to deliver water, and the height of the ground water level, as well as related to the maintenance of water infrastructure such as management of rivers, reservoirs and lakes. The third watershed downstream part is based on the function of the utilization of river water that managed to provide benefits to the social and economic interests, as indicated by the quantity and quality of water, the ability to deliver water, height of rainfall, and related to the needs of agriculture, clean water, and water management wast

Abstract

The population growth rate coupled with increased urbanization process cause increase in fulfillment ofthe Housing and Building Social supported. Due to water runoff the accretion of these buildings led toincrease in the water many translucent layers not caused and reduced the amount of open land/green space.This causes the rain water not translucent / radio infiltrated into the ground but directly runoff into drainagechannels, river or sea. Under these circumstances it is necessary to develop methods of managing rain water,rain harvesting and rain water utilizing. To cope with rain runoff that caused by rain water. One way is toapply the concept of Zero Runoff technology in general and the residential area facilities. Zero Runoff is amust to each of the building may not cause an increase of rain water discharge into a drainage channelsystem or river systems flow. Some of the concepts concept technology of Zero Runoff are Rain Water Tank,Rain and Infiltration Wells, Rain water Infiltration Pond.

Abstract

Perubahan iklim yang terjadi saat ini sebagai dampak ketidakeimbangan tingkat CO2 di atmosfer sebagai emisi dari penggunaan energi berbahan baku karbon serta prediksi kebutuhan akan energi dimasa depan, serta meningkatnya biaya pemenuhan kebutuhan listrik berbahan fosil terkait dua alasan yang melatarbelakangi Program Kemitraan Masyarakat ( PKM) ini dilakukan. PKM ini dilakukan dengan memberikan sosialisasi kepada masyarakat tentang pemanfaatan sel surya sebagai sumber energi alternatif yang sangat dekat dengan kehidupan kita setiap harinya, serta latar belakang perlunya kita mempergunakan energi alternatif tersebut di harapkan mampu membuka wawasan sekaligus memberikan motivasi kepada pihak Mitra untuk melakukan pengembangan pemanfaatannya sebagai bentuk kepedulian kita terhadap masa depan bumi yang akan datang. Dengan sampainya informasi pemutakhiran serta penerapannya kepada masyarakat, hal tersebut dapat memotivasi Mitra untuk mengembangkan pemanfaatan panel surya di SMPN 462 dengan lebih baik sehingga dapat menjadi sekolah yang mandiri dalam memenuhi kebutuhan energi listrik di sekolah tersebut. Optimalisasi tujuan PKM memerlukan keseriusan serta kepedulian dari berbagai lapisan elemen masyarakat seperti tim pelaksana, institusi tim pelaksana, serta pihak Mitra guna meningkatkan kesejahteraan kehidupan bermasyarakat serta turut menjaga kelestarian lingkungan hidup menuju Indonesia Bebas Emisi. Kata Kunci : panel surya, sel surya, energi alternatif, energi terbarukan, penyelamatan lingkungan hidup
