Masalah yang sering muncul dalam hal pengelolaan limbah rumah sakit khususnya untuk rumah sakit tipe kecil dan menengah adalah terbatasnya dana yang ada untuk membangun fasilitas pengolahan limbah serta biaya operasionalnya. Untuk mengatasi hal tersebut maka perlu dikembangkan teknologi pengolahan air limbah rumah sakit yang murah, operasionalnya mudah serta hemat energi. Salah satu cara pengolahan air limbah rumah sakit yang murah, sederhana dan hemat energi adalah proses pengolahan dengan proses biofilter anaerob-aerob tercelup menggunakan media sarang tawon. Tujuan penelitian ini adalah melakukan uji performance pengolahan air limbah rumah sakit dengan proses kombinasi biofilter tercelup anaerob dan aerob menggunakan media plastik tipe sarang tawon. Pengolahan limbah rumah sakit dengan proses biofilter tercelup menggunakan media sarang tawon cukup tahan terhadap fluktuasi debit dan konsentrasi, terlihatdari tetap tingginya angka penyisihan COD, BOD, TSS, ammonia, dan deterjen. Total efisiensi penghilangan beberapa parameter polutan selama percobaan yakni untuk COD 87,0 – 98,6 %; BOD5 93,4 – 99,3 %; Total padatan tersuspensi (TSS) 80,0 – 97,8 %; Ammonia 93,75 – 98,2 % ; dan Deterjen (MBAS) 95,8 – 99,7%.

Organotin compounds have attracted to focusing study due to theirbioaccumulative potential and deleterious effects to the aquatic organisms. These compounds are ubiquitous contaminants in the environment and have been used commercially for many years and in a variety of diverse applications as polyvinyl chloride (PVC) stabilizers, industrial catalysts, wood preservatives and biocides. Direct exposure to organotin into aquatic environments generally through the usage of TBT in antifouling paints applied for boat, marine infrastructures and aquaculture net. Due to its persistency and biological effects at various organisms, many developed countries have banned and restricted the TBT usage for boating and aquaculture purposes. In this paper the aquatic ecotoxicology of organotin based on a multidisciplinary approach is reviewed.

Natuna Island will be developed as main center of LNG mining and refineryactivities which will be located in South Cina Sea. As consequences, manyindustries will grow fast in this island, and water consumption will increasedrastically. Therefore, it is important to identify aquifer potentiality. There is manymetode of identificaton. This paper show the application of resistivity combine with Archie’s equation to identify vertical depth and horizontal profile of aquifer. From resistivity we got value of every rock formation whereas use Archie’s equation we interpreted resistivity value of good aquifer.

PEMODELAN STATISTIK HUBUNGAN DEBIT DAN KANDUNGAN SEDIMEN SUNGAI Contoh Kasus di Das Citarum â€“ Nanjung Mardi Wibowo

Kandungan sedimen menunjukkan konsentrasi zat padat yang tersuspensi dalam air. Untuk mengukur kandungan sedimen diperlukan peralatan khusus, relatif sulit, lama dan perlu biaya, sedangkan data debit sungai jauh lebih mudah diukur dan merupakan data yang selalu tersedia di tiap aliran sungai. Oleh karena itulah perlu dicari hubungan antara debit air sungai dengan kandungan sedimen dalam air sungai. Sehingga dengan adanya data pengukuran debit sungai tanpa ada pengukuran kandungan sedimen dapat diperkirakan kandungan sedimen dalam air sungai tersebut dengan cepat dan murah.Hubungan antara debit dengan kandungan sedimen untuk data DAS Citarum - Nanjung pada bulan Maret 1998 adalah : dengan analisis regresi eksponensial : Y = 0.7379 e0.0332 X dengan : koefisien korelasi (R) = 0.978 dan kesalahan baku perkiraan (SEY) = + 1.25 juta m3/hari; dengan analisis regresi berpangkat : Y = 6.7655.10-4 X2.2644 dengan : koefisien korelasi (R) = 0.985 dan kesalahan baku perkiraan (SEY) = + 1.20 juta m3/hari.Berdasarkan nilai koefisien korelasi dan nilai kesalahan baku perkiraan, maka analisis regresi berpangkat lebih sesuai dibandingkan dengan analisis regresi eksponensial untuk data kasus hubungan debit dan kandungan sedimen di DAS Citarum - Nanjung, Maret 1998.

IPAL Yogyakarta mud contains high concentration of phosphate that can polute groundwater. To study phosphate migration with matematical model needs the data of soil properties and phosphate migration characterization in that soil. The phosphate migration characterization is determine in laboratorium scale using soil colomn nethod. The soil that are used in this research are soil at IPAL location (IPAL soil) and soil at soil at Physics Engineering Department GMU (PE soil). The tracer that is used is 32P radioisotop dan the detector is Geiger Muller detector. For IPAL soil the soil mass is 20 g, soil length is 2,1 cm, water height is 20 cm, and the flow rate of water 0,0038 cm3/s. For PE soil the soil mass is 25 g, soil length is 2,2cm, water height is 20 cm, and the flow rate of water are 0,0275 cm3/s and 0,0071 cm3/s.The result shows that IPAL soil is clay class soil and PE soil is sand class soil. The IPAL soil porosity is 0,2997 and PE soil is 0,303. IPAL soil permeability is 5,6984x10-5 cm/s and the average velosity is 1,79x10-4 cm/s. On PE soil for the flow rate of 0,0275 cm3/s the soil permeability is 4,338x10-4 cm/s, average velocity is 1,2818x10-2 cm/s, distribution coefficien is 0,88 ml/g, dispertion coefficien is 8,0971x10-3 cm2/s, phosphate migration velocity is 3,6429x10-3 cm/s, and the retardation factor is 3,5186. For the flow rate of 0,0071 cm3/s the soil permeability is 1,110x10-4 cm/s, average velocity is 3,322x10-3 cm/s, distribution coefficien is 1,345 ml/g, dispertion coefficien is 2,5339x10-3 cm2/s, phosphate migration velocity is 9,8888x10-4 cm/s, and the retardation factor is 3,3594. For the higher of flow rate the migration is higher. IPAL soil has capability to hold polutans.

High concentration of ammonia in shrimps pond sediment due to the accumulation of feed excessive will become negative impact to the shrimp culture. Therefore, increasing the indigenous microbial abilities in minimizing toxicity effect of ammonia through biotransformation of ammonia into nitrite and nitrate is very important for shrimp growth and health.Isolation and identification of nitrifying microbes has been done. The number of microbes isolated form shrimps pond are six namely 2p, 2k, 3p, 1p, 3k, and 2. The number of isolated microbes in aquaculturing pond (T-bd) is five and in post harvest pond (T-pp) is three.In T-bd samples, autotroph nitrifying microbes are 2(k), 2(p) and 3(p), but 1(p) and 3(k) as heterotroph nitrifying microbes. And in T-pp samples, autotroph nitrifying microbe is 3(p), except 2 and 3(k) as heterotroph nitrifying microbes. The rank of effectivness In nitrifying activity is 2k, 3p and 2p respectively.

Paper waste is one type of municipal solid wastes that is not properly manage yet. It contributes about ten percent of MSW. Indonesia paper waste generation is about 1.6 million ton per year which 70 percent of them was recovered byscavengers and sold to the recycling paper industries. To optimize the paperwaste management, it is needed cooperation between community, private sectors and government in the MSW management. In this article, the author talks about paper waste generation and its potency, prospect and route of its market, and strategy of paper waste management.

Dalam rangka alih teknologi khususnya dalam perancangan sistem pemantauan lingkungan perairan yang murah, handal dan mandiri, maka pada tahun 2000 dimulai perancangan buoy dan sensor yang ditujukan baik bagi pemantauan perairan darat (waduk dan sungai) maupun laut. Sistem ini pada dasarnya terdiri atas seperangkat buoy pengukur serta pusat pengolahan data yang saling terhubungkan dengan telemetri radio (VHF/HF).Beberapa parameter yang dapat diukur dengan sistem sensor antara lainparameter bawah air dan permukaan air seperti tekanan udara, kecepatan dan arah angin, konduktivitas, Kelarutan Oksigen, arah kecepatan arus, tinggi gelombang kekeruhan perairan. Rekayasa dan pengembangan diarahkan pada aspek fungsi dan kinerja dasar sistem buoy yang real time. Beberapa perangkat keras dari sistem buoy antara lain ; transducer, on-board computer, conditioning signal, converter, data acquitition controller, storage media dan instrument komunikasi data.
