Abstract

Indonesia contains about one-third of the world’s total mangroves areas,but experts say more than half of the country’s mangrove forest havebeen destroyed since the 1940s. The main sustainable alternatives tocoastal aquaculture pond development within or associated withmangrove are silvofisheries and mariculture. Silvofishery is a form ofintegrated mangrove tree culture with brackish water aquaculture. Thisintegrated approach to conservation and utilization of the mangroveresource allows for maintaining a relatively high level of integrity in themangrove area while capitalizing on the economic benefits of brackishwater aquaculture. Traditional models of silvofishery is the Empang Paritmodel, which is sometimes reffered to as Tambak Tumpangsari, wasdeveloped in Indonesia, tracing its roots back perhaps over a thousandyears. The modern version of Empang Parit is today being promoted bythe Indonesian Ministry of Foretry and the Directorate General ofFisheries. Silvofisheries have been successfully developed in Indonesiasuch as in Sinjai (Sulawesi), Cikeong (West Java), Pemalang (CentralJava), and Bali.

Abstract

Air, baik air tanah maupun air permukaan merupakan sumber kehidupan yang tidak dapat tergantikan oleh apa pun dan tanpa air, manusia, hewan dan tanaman tidak akan dapat hidup terutama sebagai air minum. Tetapi dalam pemanfaatannya, masih banyak yang tidak sesuai dengan peruntukannya ataupun mempergunakan sampai diluar batas, sehingga disatu sisi banyak yang terbuang dengan sia-sia tetapi dilain sisi banyak yang membutuhkan. Penggunaan air selama dasa warsa terakhir ini meningkat disebabkan oleh beberapa faktor, antara lain oleh kegiatan manusia yang semakin bervariasi, pertambahan jumlah penduduk yang meningkat, maka jumlah air untuk kebutuhan manusia juga meningkat dan hal ini berpengaruh terhadap kualitas air. Selain itu juga berpengaruh terhadap keterbatasan air dan kondisi alam. Untuk itu diperlukan suatu system pengelolaan air yang sangat baik dengan memperhatikan akan kondisi alam dan ketersediaan akan air sehingga tercapai suatu pengelolaan yang sesuai dengan tata kelola air. Kata kunci : air, pengelolaan air, lingkungan AbstractWater, both ground water and surface water is the source of life that can not be replaced by anything and without water, people, animals and plants will not be able to live.But in its utilization, there are still many who are not as intended or use to beyond the limit, so that on one hand many are wasted in vain, but on the other side of the many in need. Use of water during the last decade has increased due to several factors, among others,by human activities increasingly varied, the number of population increases, the amount of water for human needs has also increased and this contributes to water quality. It also affects the limitations of water and natural conditions. It required a water management system is very good with attention to natural condition sand the availability of water in order to reach an appropriate management of the water governance and the availability of clean wateris needed.  Keywords: water, water management, environment

Abstract

Pencemaran sungai akibat akumulasi limbah domestik dan industri merupakan tantangan yang serius bagi kelestarian hidup biota perairan. Limbah domestik/rumah tangga yang sering dibuang ke perairan dapat mengganggu ekosistem yang ada di perairan tersebut. Sejauh ini berbagai upaya sudah mulai dilakukan industri dengan pembuatan instalasi limbah terpadu, namun upaya tersebut masih belum maksimal karena rendahnya kesadaran masyarakat dan lemahnya pengawasan dari instansi terkait. Salah satu upaya untuk mengurangi limbah domestik adalah dengan membuat biology irigation dengan memanfaatkan tanaman talas Colocasiaesculenta. Studi pemanfaatan tanaman air untuk pengolahan air limbah domestik dalam sistem biology irigation ini dilakukanuntuk mengetahui efisiensi penyerapan unsur hara oleh C. esculenta. Metode penelitian yang diterapkan adalah menumbuhkan C. esculenta dalam suatu wadah percobaan race ways yang dialiri air limbah domestic dengan sistem subsurface flow (SSF). Hasilpenelitian menunjukkanbahwa secara fisik C.Esculenta dapat tumbuh lebih baik pada substrat yang mengandung air sungai Cikapundung dibandingkan dengan C.Esculenta yang ditumbuhkan pada substrat yang ditambahkan air sumur. Hal tersebut ditunjukkan oleh perbedaan pertumbuhan panjang dan berat tanaman tersebut. Hasil analisis parameter karbon organik (C-organik), nitrogen (N-kejdahl) dan fosfat (P) pada jaringan tanaman talas (bagian daun dan akar) menunjukkan adanya peningkatan konsentrasi bahan organic dalam jaringan tanaman tersebut yang berbanding lurus dengan pertumbuhan tanaman talas (tinggi dan berat tanaman talas), sebagaimana ditunjukkan oleh konsentrasi penyerapan C sebesar 2000 mg dan N 100 mg selama 63 hari. Kata kunci : Colocasia esculenta, limbah domestik, fitoremediasi.  AbstractPollution of rivers due to the accumulation of domestic and industrial wasteis aserious challenge to the survival ofaquatic biota. Domestic waste/ household is often thrown into the water can interfere waters ecosystems. So far, many efforts have been done such as installation integrated waste treatment, but these efforts are not yet fulfill the requirement due to low awareness and lack of oversight agencies. One of the efforts to reduce domestic wasteis by making use of plant biology irrigation with Colocasia esculenta. Study ofutilization of aquatic plants for domestic wastewater treatment systems biology irrigation was conducted to determine the efficiency of nutrient uptake by C.esculenta. The research method was applied by growing C.esculenta in an experimental container -carrying raceways domestic wastewater system with subsurface flow (SSF). The results showed that physical C.Esculenta may grow well on substrates containing water Cikapundung river compared to C.Esculentagrown ona substrateis added waterwells. This is shown by the differences in growth and weight of the plants. The results of the Laboratory analysis of organic carbon (C-organic), nitrogen (N-kejdahl) and phosphate (P) on the taro plant (the leaves and roots) showed an increase nutrient in plant tissues which is directly proportional to the growth of taro plants (taro plant height and weight), as shown by a concentration of 2000 mg C sequestration and N100 mg for 63 days.  Keywords: Colocasia esculenta, domestic waste, phytoremediation.

Abstract

Fotobioreaktor adalah suatu alat yang dipergunakan dalam memproduksi mikroalga yang dapat dipegunakan untuk menyerap CO2. Kultur mikroalga pada fotobioreaktor adalah salah satu upaya untuk mengurangi emisi CO2 di atmosfer, yang merupakan bagian dari teknologi CCS (Carbon Capture and Storage). Fotobioreaktor dijalankan dengan sistem batch dalam waktu 1 siklus hidup mikroalga (10 – 12 hari). Pada tahun 2008, PTL-BPPT telah mengembangkan fotobioreaktor skala batch dengan volume 50 L untuk mengurangi emisi CO2. Dalam perancangan ini perlu dilakukan pula ujikebocoran sistem fotobioreaktor agar hasil yang dicapi benar-benar optimal. Tetapi karena kurangnya jenis mikroalga yang diujikan serta keterbatasan isolat murni adalah beberapa kendala yang dihadapi pada kegiatan perancangan ini. Dari hasil perancangan ini diharapkan didapat informasi perancangan fotobioreaktor dalam skala besar dan jenis mikroalga yang dapat menyerap emisi CO2.Kata kunci : Mikroalga, fotobioreaktor, emisi CO2

Abstract

Waste to energy now become one of the technology solution that is in many developed  countries, in an effort to reduce greenhouse gas emissions from waste. Urban organic waste is a potential source of greenhouse gases. Methane gas is an energy source that can be used as fuel. It is difficult to find land for Landfill alocation in the major cities and often becomes a difficult social problem. Structured Landfill Cell is used to treat the waste at the landfill, with the aim to use land more scalable, easier waste management and control, better sanitation, better water control leachate and gas produced can bemanaged optimally and compost can be utilized with the production and quality control.This new system was first used in Indonesia by PT Navigats Organics Energy Indonesia in landfill Suwung, Denpasar, Bali. There are 5 cells already built in Suwung and two of cells have been filled with garbage. Each cell contains 12,000 m3 soliswaste. Observations carried out on gas productivity of two cells that have been filled, with a dry treatment on cell 1 (dry cell) and a wet treatment in cell 2 (wet cell). The observed gas is CH4, CO2,and O2 as the main parameters, with the addition parameters are CO and H2S. The instrument used is the GA 2000 Plus. Observations of two cells made for 4 months, with the content of CH4 around 40 to 50% in the first month and gradually decreased to reach 18 to 25% in the fourth month. Carbondioxyde going up and down following condition of CH4 and its value ranges between 16 and 28%. Oxygen consentration around 2 to 14%.For keeping engine performance the consentration of methane should more than 28%and O2 content lower than 6%. Cell with watering will temporarily reduce CH4 and CO2 and O2 increase, but it is slowly rising again. Carbonmonoside values tend to increase with age garbage (10 sd 350 ppm), whereas irregular H2S values ranging 0 up to 24 ppm, allegedly associated with the low protein content in the trash. Sewage treatment system is proven to increase CH4 gas, yet still needed modifications of structure and the gas collector pipe system so that productivity can be improved.Key Words : Solidwaste, Metana, Cell System
