Sanitasi merupakan salah satu faktor bagian yang terpenting dalam kehidupan dan juga merupakan suatu kebutuhan dasar dalam kehidupan sehari-hari bagi manusia. Aturan-aturan yang telah dibuat oleh pemerintah tidak pernah diperhatikan lagi sehingga kualitas lingkungan tidak terjaga dan menyebabkan lingkungan kita tercemar dengan limbah. Air limbah dapat berasal dari rumah tangga (domestik) yaitu buangan kakus (black water) berpotensi mengandung mikroba pathogen dan air bekas cucian dapur, mesin cuci dan kamar mandi (grey water). Melihat kondisi tesebut, limbah rumah tangga sampai saat ini dibuang langsung ke saluran-saluran drainase yang ada melalui parit-parit dan sungai. Buangan air limbah tersebut di tampung melalui bak Instalasi Pengolahan Limbah (IPAL) yang bersifat komunal, off site sanitation atau individual dan selanjutnya lumpur tinja dari bak IPAL tersebut di olah ke Instalasi Pengolahan Lumpur Tinja (IPLT) dengan menggunakan mobil tinja atau motor tinja. Dengan melihat cakupan layanan IPLT yang baru mencapai 5,2%, dapat diduga bahwa 39,06% pengolahan air limbah sistem setempat masih belum efektif. Penelitian ini menggunakan metode deskriptif yaitu prosedur pemecahan masalah yang diselidiki dengan menggambarkan keadaan subjek atau objek dalam penelitian pada saat sekarang berdasarkan fakta-fakta yang tampak atau apa adanya. Penelitian ini difokuskan pada kondisi dilapangan melalui wawancara dan obesrvasi sampai dengan pengolahan. Prakiraan timbulan limbah cair pada 20 tahun kemudian diproyeksikan timbulan/buangan air limbah di Kota Pontianak akan mencapai 79.515 M3/hari dengan debit air limbah mencapai 920 liter/detik, maka diproyeksikan kebutuhan Instalasi Pengolahan Air Limbah Komunal ini di Kota Pontianak mencapai 269 unit dengan layanan kepada sekitar 138.793 penduduk. Sistem penyaluran air limbah cair rumah tangga tersebut ke penampungan dan seterusnya diolah di IPLT yang telah tersedia. Dalam penanganan lumpur tinja di Kota Pontianak dilakukan pengangkutan/penyedotan lumpur tinja, pengolahan lumpur tinja dan penanganan lumpur keringKata-kata kunci: sanitasi, proyeksi, limbah rumah tangga, instalasi pengolahan air limbah komunal, instalasi pengolahan lumpur tinja

Wastewater management appeared about 3000 BC in South Asia, and spread on the whole subcontinent with the development of urbanization during its early history. Domestic grey water and black water were canalized through street-side drains, and cesspits was implemented at house outlet level, or at drain crossing, in order to avoid the clogging of the system. Nothing seems to be known about the ultimate place where the drains canalized wastewater. In South India, wastewater was managed previously to the 1st century AD, at the very same period as the presence of Mediterranean population on the subcontinent. But, we cannot confirm a Mediterranean influence on wastewater management, because of the previous development of several techniques in the region. In today rural Puducherry area, traditional techniques are used to manage wastewater, quite similar to the method used to treat wastewater of Puducherry urban zone.

Lemuru fish is one of fishery commodity that has high economical value and one of fish that most catched by fisherman in Bali Strait. Lemuru fish had been caught in Bali Strait was fluctuating every month and every years. This condition was related with food source of Lemuru fish such as phytoplankton and zooplankton. So this research was conducted to explained the relationship phytoplankton and zooplankton abundance with Lemuru fish catched  in Bali strait. This study focus in Bali strait during March until May 2017. Determination of sampling point used area sampling method while water sampling occured in surface water with pouring method. Total of phytoplankton and zooplankton abundance in Bali strait in March until May had formed the sinusoidal model with their abundance ranged 301 ind/L – 604 ind/L and 7 ind/L – 12 ind/L. Plankton abundance in Bali strait in March until May (transisonal season 1) was categorized low abundance if compared with plankton abundance in another season. The low value of phytoplankton abundance caused by non upwelling phenomenon and grazing process and the low abundance of zooplankton caused by low rate of zooplankton and predation by Lemuru fish. Phytoplankton and zooplankton abundance had  strong relationship with Lemuru fish catched with correlation coefficient value 0.76 and 0.69. This condition caused by phytoplankton and zooplankton are source of Lemuru fish food.

Current interest in the fate of agrochemicals applied to turf is encouraging many turf scientists to contemplate renovation of existing field plots for soil-water monitoring studies. Ceramic cup samplers are used for these studies and result in little soil profile disturbance. However, a limitation to using this tool is frequent sampler failure caused by frequent system air leaks. Also, conventional installation and sampling require that samplers be accessible from above the soil line. This imposes a constraint on turf maintenance and increases traffic and wear to turf plots. Herein, an inexpensive offsite soil-water sampling method using permanently installed ceramic cup samplers that allows for routine turf maintenance without system failure is described. Thirty-six separately irrigated 4 m2 plots each with an installed sampler provided daily data over 1988-1989, from which the effects of a range of irrigation, N, K, and propoxur treatments on soil-water concentrations were evaluated. These data, plus calculated percolation provided an estimate of groundwater loading.
