Puskesmas menghasilkan limbah pada setiap aktivitasnya. Limbah yang dihasilkan berbentuk cair dan padat. Limbah yang tidak tertangani dengan baik akan mencemari lingkungan disekitar Puskesmas. Maka, penelitian ini untuk mengetahui bagaimana proses penanganan pengelolaan limbah cair dan padat di Puskesmas Surabaya Utara apakah sesuai Peraturan Gubernur Jawa Timur No.72 Tahun 2013 tentang Baku Mutu Limbah Cair Untuk Kegiatan Rumah Sakit. Penelitian ini mengunakan pendekatan kualitatif dengan studi kasus deskriptif. Pengumpulan data dilakukan dengan wawancara, observasi, pendataan komposisi limbah cair, berat limbah padat,dan cara pengolahannya. Hal ini dilakukan dengan menggunakan kuesioner yang telah dibuat oleh peneliti dan dibacakan pertanyaan kepada pihak puskesmas. Pengelolaan limbah cair dan padat Pusat kesahatan masyarakat di Surabaya Utara tidak terlalu baik. Beberapa Puskesmas memiliki Instalasi Pengolahan Air Limbah (IPAL). Kuantitas limbah cair Puskesmas sebesar 1,47 m3/hari - 2,57 m3/hari , pada kualitas limbah cair beberapa parameter belum memenuhi baku mutu untuk TSS, NH3-N Bebas, PO4, dan Total Colifrom. Rekomendasi untuk Puskesmas yang telah memiliki IPAL adalah pengecekan proses aerasi, pembersihan media secara teratur dan penambahan dosis klor. Puskesmas yang tidak memiliki IPAL disarankan membangun IPAL jenis Biofilter dengan proses yang lebih baik dari sebelumnya. Limbah padat di golongkan menjadi 3 jenis yaitu limbah padat medis, basah dan kering. Berat rata – rata sampah basah mencapai 5625 gr, sampah kering 9439 gr, 2190 gr untuk sampah medis. Rekomendasi limbah padat adalah tempat sampah sesuai dengan jumlah volume sampah, dilengkapi dengan pelabelan, dan warna kantong plastik yang mengacu pada KepMenKes R.I. No.1428/MENKES/SK/XII/2006

Water is the natural resources have the function of very importance for human life and also as authorized capital in development. Water will influence by the other component. Exploiting of water to support all human life must done with wise action to management so that not result damage at water resource. As place relocation of water hence river have the selected capacities that able to change because natural activity and antropogenik. This research was conducted in nine major rivers in East Java. The objectives of this study were: 1) Identifying the characteristics and concestration range of water quality parameter, 2) Comparison the level of pollution in rivers in East Java. The results of this study indicated that the characteristic of water quality parameter of rivers in East Java were generally physical, chemical and biological. The comparison result of water quality parameter basically showed that in general the pH was still under threshold that had been determined, that was pH from 6 to 9. In general, DO concentration ranged from 0.5 mg/l to 7 mg/l, BOD concentration ranged from 3 mg/l to 11 mg/l and the COD concentration ranged between 0.5 mg/liter to 35 mg/l.

Salah satu cara untuk mengidentifikasi arah penyebaran polutan di sungai dan mendapatkan hasil penelitian yang mendekati sebenarnya dengan menggunakan model matematik. Kajian dari model tersebut diselesaikan dengan menerapkan metode beda hingga, yang dalam hal ini menggunakan metode beda hingga eksplisit Leap frog. Hal ini dikarenakan metode tersebut relatif mudah untuk ditangani. Untuk membuat struktur model matematik selain metode beda hingga diperlukan juga hukum dasar hidrodinamika aliran di sungai yaitu persamaan kontinyuitas dan persamaan gerak atau momentum. Tanpa kedua persamaan tersebut pembaganan Leap frog tidak dapat dibuat. Sebagai solusi numerik, untuk mencapai keberhasilan model matematik aliran air di sungai dengan menggunakan metode beda hingga eksplisit Leap Frog tersebut, tergantung pada rasio dari pembaganan waktu dan ruang. Dalam hal ini berarti kajian stabilitas numerik dari model harus dipenuhi persyaratannya.

To lengthen the life of solid waste final disposal site (TPA) the mass flow of solid should reduced by reduction, recycling and solid waste processings. The mass flow can be determined by surveys of the waste mass at source, at temporary disposal site (TPS) and TPA. The survey was done at markets, commercial, housing areas of high, medium and low income groups. Recycling rate of solid waste in Surabaya City was 16%, 13% at TPA and 3% at TPS. The solid waste generation was 5.655 ton/day and those which enter the was 3.118 ton/day. Solid waste that was deposited at TPA was 2.896 ton/day.

This research used constructed wetland system. Flow rate variation used 7,5 l/day, 11,25 l/ day and 15 l/ day with 2 controls. The measurement was done to the concentration of BOD5, N-total, P-total, K-total, coliform and percentage of the rice leaves which were infected. Liquid wastewater from septic tank was used for reactor influent. The results showed decreases BOD5 concentration 91,04% at flow rate 11,25 l/day (Hydraulic Loading Rate = 62,5 l/hari.m2) and the wastewater nutrient concentration for N 55,91% at flow rate 11,25 l/day, P 99,61% at flow rate 15 l/day, K 12,59% at flow rate 11,25 l/day and decreases coliform concentration 98,51% at flow rate 7,5 l/day.

the Regional Government is the fulfillment of basic needs of daily drinking water. However, the service by PDAM is still not optimal. It can be seen from the PDAM's performance that was “unhealthy from year to year according to BPPSPAM data. Some of the research methods used in analyzing PDAM performance are problem identification, identification of variables and conceptual models, dynamic model simulations, analysis and interpretation as well as drawing conclusions and suggestions. From the simulation result of dynamic models using Vensim PLE plus software, alternative scenarios were obtained, that will increase domestic water consumption and customer connections by 12.5% per year, increasing the repair and replacement of distribution piping systems and customer meters by 20% per year, and increasing rate to 15% per year.
