Tujuan Program Pengabdian kepada Masyarakat Multi 2-1 adalah perbaikan kondisi lingkungan di wilayah Kelurahan Krendang, Kecamatan Tambora, Jakarta Barat. Mitra dari kegiatan ini adalah pengelola non profit RPTRA (Ruang Publik Terpadu Ramah Anak) Krendang. Permasalahan yang dihadapi RPTRA Krendang dengan banyaknya pengunjung adalah tingginya konsumsi air yang berkorelasi dengan tingginya tagihan/rekening PDAM. Saat ini RPTRA menggunakan air dari saluran drainase sekunder untuk menyiram kebun/tanaman sebagai upaya dalam mengurangi pemakaian air PDAM, namun masuknya pencemaran air limbah domestik maupun non domestik ke saluran drainase menyebabkan penggunaan air dari saluran drainase berpotensi untuk menyebarkan logam berat dan bakteri pathogen ke dalam tanah. Metode pelaksanaan pengabdian ini yaitu (i) survey melalui wawancara untuk mengetahui kebutuhan pengelola RPTRA, (ii) pendampingan pada pengelola RPTRA agar dapat merencanakan dan membangun konstruksi sederhana guna memanfaatkan air bekas pakai (reuse) untuk menyiram tanaman, dan (iii) memberikan materi edukasi hemat air yang ditujukan pada warga/pengunjung RPTRA. Adanya pemanfaatan air bekas pakai sebagai air penyiram tanaman melalui implementasi konstruksi sarana dalam pemanfaatan air bekas pakai, yaitu tangki penampung dan pengalihan saluran air, pemasangan pembatas aliran yang dapat mengurangi konsumsi air di kran hingga 40%, serta pemasangan poster di RPTRA Krendang yang dapat memberikan edukasi kepada masyarakat agar berperilaku hemat air, terbukti hal-hal tersebut dapat memperbaiki kondisi lingkungan di RPTRA Kelurahan Krendang, Kecamatan Tambora, Jakarta Barat

Industrial waste that contains heavy metal can cause environmental problem because of its toxicity, persistency and accumulation level in the environment. Biosorption process is highly influenced by temperature, pH, light, contact time, and ratio of surface area. Microalgae which possess two functional groups that are able to react on metal ion in a solution can be exploited to overcome environmental pollution due to heavy metal compound. Closed cultivation system in a photobioreactor is utilized to overcome contamination and evaporation problems on open pond system. Heavy metal analysis is conducted by utilizing Atomic Absorption Spectroscopy (AAS), Fourier Transform Infra-Red (FTIR), and Scanning Electron Microscope (SEM). This article provides information on biosorption as alternative technology to overcome heavy metal in water areas with no side effects on the environment with advantages of the absence of secondary pollutants, high level of efficiency, and relatively economic compared to physic-chemical method heavy metal removal methods

Apartment planning includes reservoir size planning and pumping systems for reservoirs and their distribution systems. In determining the optimal size for the reservoir, comparative data is needed from other apartments with relatively the same specifications. The data is processed to determine the maximum and minimum average water usage in a certain period of time. The optimum reservoir size can be determined based on the results of the data processing. So the method of calculating fluctuations in water use is needed to determine this, but not every apartment has the same pumping system. This research is intended for data collection in apartments that do not have definite pumping hours. The result of study shows that this method can be applied to apartments without solid timing for pumping water.
