Humans need drinking water in life and up to 70% of the human body is water. Consuming enough mineral water for the body can help the process to facilitate digestion, regulate metabolism, regulate food substances in the body and regulate body balance. 46.1% of adolescents from 1200 respondents studied when feeling thirsty prefer instant drinks compared to consuming mineral water, this causes mild dehydration with symptoms: dry lips up to the throat, body weakness. This study aimed to analyze the levels of biological and chemical parameters in alkaline water of various brands in Surabaya which were coded KW, M, P and T. This study was experimental with a post-test only control group design. The research data were statistically tested using one-way ANOVA with the aim of analyzing the levels of biological (E.Coli and MPN Coliform) and chemical (arsenic, fluoride and total chromium) parameters in alkaline water (KW, M, P, T). E.coli parameters in 4 types of alkaline water which were coded KW, M, P and T met the standard requirements, namely 0 colonies/100 ml. Chemical parameters namely arsenic met the requirements of 0-0.1 ppm, fluoride met the requirements of 0.01-1.5 ppm and total chromium met the requirements of 0.01-0.05 ppm. In accordance with the results of the examination, it is revealed that the process of making and producing alkaline water of various brands in the market under study are following the Good Food Production Methods (CPPB), thus there is no E. Coli and MPN Coliform content. Suggestions can be given to future researchers and the community; future researchers need to conduct further research on other brands of alkaline water in various areas with a wider range while the community needs to be more selective and smart in choosing alkaline water to be consumed to maintain a healthy body so they can benefit it at an affordable price.

harus dilakukan pengolahan sebelum dibuang ke lingkungan. Penurunan COD dan Amonia dilakukan dengan adsorpsi karbon aktif. Tujuan penelitian ini untuk mengetahui efektifitas karbon aktif ampas tebu dalam menurunkan kadar COD dan Amonia. Metode penelitian ini yaitu One Group Pre-Post Test Design pada perbedaan variasi dosis 2,3, dan 4 gram. Karbon aktif dibuat dengan karbonisasi suhu 320oC selama 30 menit, ayakan 100 mesh, aktivasi dengan HCl 0,1 M selama 24 jam, pembilasan dengan aquades hingga pH 7 dan pengeringan suhu 150 oC selama 2 jam, pengolahan limbah cair dengan karbon aktif ampas tebu sistem batch. Hasil penelitian yaitu karbon aktif dengan dosis 2 gram menurunkan kadar COD sebesar 44,87% dan penurunan kadar Amonia sebesar 51,8%. Dosis 3 gram menurunkan kadar COD sebesar 69,86% dan Amonia sebesar 71%. Dosis 4 gram menurunkan kadar COD dan Amonia sebesar 540,97 mg/L atau 84,72% dan pada parameter Amonia sebesar 84,6%. Hal ini terjadi karena dosis atau Jumlah adsorben yang makin banyak akan memberikan luas permukaan yang makin besar bagi adsorbat untuk terdesorpsi. Dari penelitian ini dapat disimpulkan bahwa dosis yang mampu menurunkan kadar COD dan Amonia paling besar hingga memenuhi persyaratan baku mutu adalah 4 gram. Saran bagi penelitian selanjutnya agar melakukan penambahan dosis untuk menemukan dosis optimum.Kunci: Ampas Tebu, COD, Amonia

Community health centers are releasing infectious wastewater that must be treated using a Wastewater Treatment Plant (WWTP). The performance of WWTP will affect the quality of effluent wastewater, while the quality has been determined by the Governor of East Java Regulation No. 72 of 2013, so as not to pollute the environment. This research purposed to evaluate the management of WWTP incommunity health center in Surabaya, which covers the north, south, east and west. This research analyzed the installation of 5 wastewater treatment plants, consisting of 2 WWTP Non-Inpatient Health Centers with the highest population category, and 3 Inpatient Health Centers with the highest number of beds. Data collection was obtained from observations, interviews and laboratory tests. Wastewater samplings were carried out at the inlet, after filtration and outlet. Data were analyzed descriptively and compared with East Java Governor Regulation No. 72 of 2013 and WWTP Technical Guidelines. The results of the research showed that the effluent quality of the Surabaya City Health Center wastewater treatment plant has met the quality standards. The discharge of wastewater community health centersnot exceed the maximum discharge of wastewater, but the Tanah Kalikedinding and the Jagir Health Center produced wastewater exceeding the discharge capacity of WWTP, so that the performances becomes less efficient. In terms of management, only Dr. Soetomo health center had sufficient grades, while others got excellent grades.

Delta Fishing is a fishing ponds and family recreation areas located in Sidoarjo Regency. Activities at Delta Fishing generate untreated fish wastes and food leftovers, leading to problems such as odor around the site. The purpose of this study was to utilize fish wastes and leftovers* for fish feed pellets in Delta Fishing of Sidoarjo Regency. This study was a pre-experiment using the posttest-only design. Objects were subjected to several treatments and pretests by utilizing the fish wastes and leftovers as raw materials for the manufacture of fish feed pellets for gouramis of 5-15 cm in size. Each sample treatment was replicated 5 times and subjected to laboratory tests to determine the contents of protein in the fish pellets. Results showed that the fish pellets made from fish wastes had an average protein content of 59.2% and those made from leftovers had 32%. There was a difference in the average protein content of pellets made from fish wastes and those made from leftovers with a p-value of (0.000 <0.05). Conclusion of this study, fish pellets with good protein contents derived from leftovers with a protein content of 32%, in contrast to those made from fish wastes with a protein content of 59.2%. The management of Delta Fishing is recommended to use the findings of the present study to evaluate and solve waste generation that may lead to the inconvenience of visitors and residents around Delta Fishing.   Keywords :  Fish wastes and leftovers, fish pellets.

Ekowisata atau Wisata Alam adalah kegiatan pariwisata yang bertanggung jawab atas kawasan / kawasan yang masih alami yang dikelola sesuai kaidah alam, dengan tujuan menikmati keindahan alam yang melibatkan unsur edukasi, pemahaman dan dukungan bagi upaya pelestarian alam serta peningkatan pendapatan dan kesejahteraan. Komunitas lokal. Pengembangan ekowisata / desa wisata berkelanjutan berbasis pemberdayaan masyarakat merupakan upaya memasukkan peran masyarakat dalam kegiatan desa / kelurahan wisata yang dikenal dengan istilah “Community Based Development”. Tujuan dari program Pengabdian kepada Masyarakat adalah untuk meningkatkan kesehatan lingkungan dan wawasan dalam bidang kesehatan lingkungan serta meningkatkan kualitas hidup masyarakat khususnya masyarakat Desa Wonorejo Kecamatan Rungkut Kota Surabaya.Kegiatan pengabdian masyarakat yang dilakukan dalam Ekowisata Mangrove yaitu pelestarian lingkungan berupa reboisasi / penghijauan dengan penanaman pohon dan mangrove. Penanaman 3000 avicennia marinaa tanaman mangrove di laut, pemberian bibit tanaman dan penanaman 3000 avicennia marinaa tanaman mangrove melibatkan Dinas Perkebunan dan Pertamanan. Pada tanggal 26 dan 27 Oktober 2016 telah ditanam 300 tanaman mangrove avicennia marinaa, dan setelah dilakukan evaluasi hingga 10 November 2016 telah ditanam 3000 tanaman mangrove avicennia marinaa. Rekomendasi yang dapat diberikan kepada peneliti lain adalah melakukan uji konsentrasi Pb, lahan dan berbagai jenis tumbuhan guna mengembangkan ilmu pengetahuan dan teknologi untuk menentukan fitoremediasi menggunakan tumbuhan. Rekomendasi yang dapat diberikan adalah perlunya evaluasi secara berkala terhadap fungsi mangrove jenis avicennia marinaa yang telah ditanam di Ekowisata Mangrove.
