Abstract

Carbon dioxide (CO2 )gases that dominated by anthropogenic activities causevarious negative impacts on the environment and surroundings due to increasing itsconcentrations in the atmosphere. There are some techniques to mitigate againstthe increase of CO2 which one is the utilization of phytoplankton cultured in a photobioreactor (FBR) as an natural absorber. In this study, the influence of input gas CO2flowrate on Chlorella sp at multiple tubular air lift photobioractor (FBR) was measuredin milk factory field. The CO2 flowrate continuesly was controled by 2 l/min and 1.5 l/mduring experiment. Result showed that Chlorella sp. have a good adapted ability of CO210-15% vol industrial emition. The experiment result stated that reactor capability atFBR-1 was lower than FBR-2. The reactor capability at FBR-1 and FBR 2 were 0,78 ±0,25 and 0,92 ± 0,36 g/l. media/day.

Abstract

Dalam penelitian ini, dikembangkan suatu metode analisa Cu dengan menggunakan peralatan pemekatan yang telah dikembangkan sebelumnya(1). Dengan ini dimungkinkan dapat dilakukan analisa Cu dengan konsentrasi yang sangat rendah. Ion Cu pada kadar rendah (trace concentration) dalam sampel cair direaksikan dengan Diethyldithio Carbamate (DDTC) untuk menghasilkan senyawa komplek Cu- DDTC. Larutan yang mengandung senyawa kompleks tersebut selanjutnyadipekatkan kedalam Micro Membrane Filter (MMF) menggunakan alat yang telah dikembangkan(1) dan MMF yang telah mengandung senyawa komplek tersebut kemudian secara langsung dimasukkan ke dalam Graphite Furnace Atomic Absortion Spectrophotometric (GF-AAS) untuk meanalisa konsentrasi Cu secara langsung. Dengan metode ini, sensitivitas (3 x σ larutan blanko) Cu(II) adalah 0,03 ppb dan relative standard deviation (n=6) adalah 2,5 %. Metoda ini telah diterapkan untuk menganalisa kandungan ion Cu dalam sampel air sungai dengan hasil yang sangat memuaskan.

Abstract

Salah satu hasil proses biodegradasi sampah di TPA adalah lindi yang merupakan polutan organik yang berbahaya bagi lingkungan karena berpotensi mencemari tanah dan air tanah. Penelitian ini bertujuan untuk mengetahui kuantitas dan kualitas lindi dari sampah di TPA Kaliwlingi Brebes melalui uji lisimeter. Kuantitas lindi penting untuk memperkirakan spesifikasi disain unit pengolahan termasuk metode pengolahannya. Sedangkan karakteristik lindi penting untuk menentukan efisiensi pengolahan atau target kadar polutan yang diinginkan agar sesuai standard baku mutu. Dari pengamatan diperoleh kuantitas lindi per massa sampah rata-rata mencapai 1.060 liter/kg, sedangkan nilai pH lindi rata-rata 7,6 atau cenderung alkaline. Dari data pengamatan, semakin tinggi kadar air akan semakin besar kuantitas lindi yang dihasilkan. Karakterisasi lindi terhadap parameter BOD5, COD, NH3-N dan TKN menghasilkan nilai yang bervariasi. Nilai rata-rata serta rentang minimal-maksimal yang didapat; BOD5 90,7 mg/l (65 mg/l-130 mg/l), COD 9.679,7 mg/l (6.300 mg/l-12.200 mg/l), NH3-N 134,4 mg/l (80 mg/l-190 mg/l) dan TKN 672,5 mg/l (540 mg/l-890 mg/l). Rasio BOD5/COD sebesar 0,01 menunjukkan tingkat low biodegradability dalam materi organiknya, hal ini disebabkan waktu pengamatan yang relatif singkat dan proses degradasi biologis masih berlangsung.Nilai rasio BOD5/COD yang diperoleh belum menunjukkan nilai yang representatif untuk sampah di TPA Kaliwlingi. Hasil dari karakterisasi lindi untuk beberapa parameter  menunjukkan bahwa biomassa atau sampah yang diteliti tergolong usia muda dan masih dalam proses dekomposisi.Kata kunci : karakterisasi, produksi, organik, lindi, TPA sampah

Abstract

Principally, solid waste management is all activities of solid waste handling, from thepoint sources until the final disposal. Up to know solid waste management in urban areais still a complex problem, either from social, management, and technology aspects.The other problem of solid waste management is due to the people behaviour, whichis mostly still unaware. Social capacity is another word social capital means a socialcondition that a lot of citizens participate the process of decision making or policymaking and cooperation with government. The role of community in this system is onlyin paying the monthly fee. So that people still fully gave the solid waste managementsystem in to the government. There is no indication of solid waste sparation by thepeople them selves.

Abstract

Proses produksi crude palm oil (CPO) dan biodiesel kelapa sawit menghasilkan limbah padat sebanyak 35-40% dari total tandan buah segar (TBS) yang diolah, dalam bentuk tandan buah kosong, serat, cangkang buah dan abu bakar. Keberadaan limbah yang melimpah ini berpotensi mencemari lingkungan bila tidak tertangani dengan baik. Penelitian ini bertujuan untuk membahas dan menghitung potensi limbah padat sawit menjadi energi terbarukan dan pengaruhnya terhadap peningkatan nilai net energy ratio (NER) dan net energy balance (NEB). Dalam penelitian ini digunakan metode life cycle assessment (LCA) untuk menghitung neraca limbah padat yang hasilnya akan dikonversikan ke dalam nilai faktor energi dari sumber pustaka yang terpercaya. Hasil neraca massa limbah sawit menunjukkan bahwa total limbah padat serat dan cangkang yang dihasilkan setiap pengolahan 1 ton TBS adalah 130 kg dan 65 kg. Limbah ini bila digunakan sebagai bahan bakar boiler akan berpotensi menghasilkan energi sebesar 10.118 MJ/ton biodiesel. Tambahan energi terbarukan ini akan meningkatkan nilai NER dan NEB secara signifikan. Nilai NEB naik 27.199 MJ menjadi sekitar 37.317 MJ (37,2%) dan nilai NER naik dari 3,19 menjadi 4,01 atau meningkat 25,5%.Kata kunci : CPO, biodiesel, kelapa sawit, limbah padat sawit, NER, NEB, LCA

Abstract

Dalam penelitian ini telah dilakukan penelitian untuk mengetahui pengaruhpenambahan ion-ion logam di dalam media padat terhadap pertumbuhanbakteri protease, serta pengujian pengaruh konsentrasi substrat protein dalam media cair terhadap aktivitas proteolitik bakteri. Penambahan ion logam Mn, Co, Cu dan Zn ke dalam media padat telah mampu meningkatkan pertumbuhan bakteri protease yang ditunjukkan melalui peningkatan jumlah produksi enzim ekstraseluler disekitar tempat tumbuh isolat. Diantara ion-ion logam yang digunakan, ion Mn memberikan hasil yang sangat baik dibanding dengan ion-ion lainnya. Penambahan konsentrasi substrat protein pada media cair sebanyak 24%~40% telah mampu meningkatkan aktivitas protease bakteri, sedangkan penambahan 8%~16% substrat ini justru menghambat aktivitas bakter. Hasil penelitian ini diharapkan dapat menjadi dasar untuk mengoptimalkan proses pembuatan chitin dengan bahan baku limbah cangkang rajungan secara biologis, yang dipandang sebagai proses yang lebih ramah lingkungan dibandingkan dengan proses secara kimiawi.
