Abstract

The agroforest region is bestowed with diverse agro-climatic zones, whichmakes itself a rich storehouse of different types of Flora and Fauna.Besides, this conditions help in introduction, acclimatization, andcultivation of a number of aromatic plants with minimum efforts. Thereare a few commercial crops, which can be cultivated without disturbingthe existing flora and have the potential to establish as cash crops inthis region.Patchouli (Pogostemon cablin) has been identified as one such essentialoil bearing aromatic plant with immense export potential. Patchouli oilproduction could be a rural based, labour intensive, low cost agro-basecottage industry, which will give large-scale employment in rural and hillyareas. Patchouli, being a shade loving plant can easily be grown as anintercrop amidst fruit trees, arecanut, and coconut plantation etc. It canalso be easily cultivated in flood free fallow or wastelands. This will providesome extra income for the farmers. Following figures clearly indicatesthat Patchouli cultivation can be a good option besides the traditionalcrops.

Abstract

ABSTRACTThe problem for big cities in implementing the MSW disposal method is the  land availability. Hierarchically, a suitable method for solving this condition is not to dispose the MSW into the landfill but to treat it in the thermal processing, such as incineration. The bonus of this incineration is the heat dissipation that can be utilized to generate electricity. Burning MSW through incinerator that converts into energy is often called a Waste to Energy (WtE) or PLTSa.  Beside the benefit of the high temperature flue gas that can produce electricity, PLTSa also emits major pollutants in the flue gas such as particulates, SO2, NOx, CO, HCl, dioxins and furans. In order to meet the emission standards, the PLTSa design has to be equipped with APCD’s such as cyclone, semi-dry scrubber and bag filter. ID fan withdraws the flue gas into the chimney before discharging it into the ambient air through the top exit of chimney. The main parameters in the design of the ID fan and chimney are the quantity, quality and temperature of the flue gas as well as the environmental parameters, such as air temperature, atmospheric stability, wind speed and direction. The design of the chimney was carried out with a technical calculation approach, simulation of Gaussian dispersion model and the compliance of related regulations from the MoEF. In the design of PLTSa with a waste capacity of 350 tons/day, specification of the stack is 2.02 m diameter and the 70 m height whereas ID fan is 70,000 cfm flue gas flowrate, 400 BHP power, 80% mechanical efficiency and  25 inch H2O pressure pump.Keywords: Waste-to-energy, flue gas, ID fan, chimneyABSTRAKSalah satu masalah bagi kota-kota besar dalam menerapkan metode pengolahan sampah adalah ketersediaan lahan. Secara hierarkis metode yang mampu memenuhi kondisi ini adalah pengolahan dengan metode termal sekaligus memanfaatkan buangan panas yang ada untuk membangkitkan energi listrik. Pembakaran sampah dengan insinerator yang merubah sampah menjadi energi ini sering juga disebut   Pembangkit Listrik Tenaga Sampah (PLTSa). Salah satu hasil samping PLTSa adalah flue gas yang temperaturnya tinggi serta mengandung polutan utama seperti partikulat, SO2, NOx dan CO.  Agar memenuhi baku mutu emisi,  rancangan PLTSa dalam studi ini dilengkapi dengan unit cyclone, semi dry scrubber, bag filter dan ID fan serta cerobong sebagai unit pembuangan akhir flue gas. Sebagai unit akhir pembuang flue gas ke lingkungan, peran cerobong sangat penting sehingga perlu beberapa pendekatan dalam perancangan. Parameter desain utama dalam perancangan cerobong adalah kuantitas, kualitas dan suhu dari flue gas serta parameter meterologis lingkungan seperti suhu udara, stabilitas atmosfer, kecepatan dan arah angin. Dalam perancangan cerobong pada studi ini dilakukan dengan pendekatan perhtiungan teknis, simulasi model dispersi Gaussian serta peraturan terkait dari Kementerian Lingkungan Hidup dan Kehutanan. Dalam rancangan PLTSa  dengan kapasitas olah sampah 350 ton/hari ditetapkan diameter cerobong 2,05 m dengan tinggi 70 m, serta diperlukan ID fan sebagai pendorong flue gas dengan spesifikasi Q = 70.000 cfm, BHP = 400, mechanical efficiency 80% dan static pressure pompa = 25 inch H2O.Kata kunci: Sampah menjadi energi, gas buang, ID fan, cerobong

Abstract

Indonesia, a nation with more than 230 million population, is the world’s largest archipelagic state located between Asia and Australia continents. In 2000, the production of municipal solid waste (MSW) or refuse in 384 Indonesian cities was about 80,235 tons or 320,940 m3 per day. Refuse generation is predicted to increase five times by 2020. Waste composition is influenced by external factors, such as geographical location, the population’s standard of living, energy source, and weather. Generally, ahigh percentage of organic matter of refuse is between 61 and 72 per cent by weight. The presence of paper, plastic, glass, and metal ranges from 0.4 to 13 per cent. The current handling of refuse in Indonesia is mostly used the disposal land of unhealthy landfill in the form of open dumping. Around 450 units of open dumping have been in operation in Indonesian big cities. These open dumping landfills cause some problems ranging from odor to health problems. Center of Environmental Technology, BPPT has been preparing to carry out landfill mining both for its compost and gas. The gassampling must be done first before it is pumped for energy use. The gas is suggested to be utilized for generating energy, for example for electricity. Initial test indicated that the composition of methane gas (CH4) is around 50%, which is a good enough for energy generation. If the percentage of burnable gas is too low to be used for generating electric energy, it might be mixed with high content of heating value of natural gas (dual fuel system). This paper will present the conditions of open dumping of landfill inIndonesia, and the status and the distribution of its containing gas. From this knowledge of the amount and distribution of landfill gas, it will be analyzed for suggestion how the mined gas will be suitably utilized by the people.

Abstract

ABSTRACTSerang District is one of the flood-prone areas, that about 20 subdistricts were affected by the flood in Serang District. Problems of clean water necessity occurred in the flood area, especially water quality in both of surface water and groundwater. To know the condition of clean water in Serang District, it is necessary to study the quality of water both surface water and groundwater in the flood-prone areas. The study was conducted by water sampling and in-situ water quality measurements at 28 open-pit points used by communities and river bodies in the potential flood in 2012-2015. In-situ physical water quality measurements are performed during sampling of well water and river water using multiparameter quality checker equipment. Water quality parameters that were measured in-situ are total dissolved solids (TDS) and turbidity. Laboratory tests of water samples were performed for suspended solids (TSS), Ammonium (NH3-N), Iron (Fe), Manganese (Mn) and total hardness parameters. The standard method of water quality analysis of these parameters is carried out using Indonesian National Standard SNI 06-6989.3-2004 water and wastewater. Turbidity tends to increase towards the downstream of the river indicating additional sediment material is transported downstream. The high total suspended solids in the river, especially in Kragilan, is caused by the waste from high domestic, commercial, and industrial activities in the area. Generally, groundwater and surface water in the flood areas at the study sites still largely indicate that quality is still feasible for consumption by the community, except for high Fe and Mn content and NH3-N in some wells due to the influence of surface water entering groundwater.Keywords: Serang district, water quality, flood areas, water supply ABSTRAKKabupaten Serang termasuk wilayah yang rawan banjir, dari 29 kecamatan yang ada sekitar 20 kecamatan pernah terkena dampak banjir. Permasalahan kebutuhan air bersih terjadi pada kawasan banjir tersebut, terutama kualitas air baik air permukaan maupun airtanah. Untuk mengetahui secara rinci kondisi air bersih di kabupaten Serang, maka perlu dilakukan kajian kualitas air baik air permukaan maupun airtanah pada kawasan rawan banjir tersebut. Kajian dilakukan dengan pengambilan sampel air dan pengukuran in-situ kualitas air pada 28 titik sumur terbuka yang digunakan oleh masyarakat dan badan air sungai pada wilayah potensial genangan banjir tahun 2012-2015. Pengukuran kualitas air fisik secara in-situ dilakukan pada saat pengambilan sampel air sumur dan air sungai dengan menggunakan peralatan multiparameter quality checker, adalah: zat padat terlarut (total dissolved solids/TDS) dan turbiditas/kekeruhan. Sedangkan pemeriksaan laboratorium terhadap sampel air dilakukan untuk parameter zat padat tersuspensi (total suspended solid/TSS), Amonia bebas NH3-N), Besi (Fe), Mangan (Mn) dan kesadahan total. Metode standard analisis kualitas air terhadap parameter-parameter tersebut dilaksanakan menggunakan Standard Nasional Indonesia SNI 06-6989.3-2004 air dan air limbah. Kekeruhan cenderung meningkat ke arah hilir sungai menunjukkan adanya tambahan material sedimen tertransport pada bagian hilir. Tingginya zat padat tersuspensi pada sungai khususnya di Kragilan akibat dampak limbah dari aktivitas domestik, komersial dan industri yang tinggi di daerah tersebut. Secara umum airtanah dan air permukaan pada daerah banjir di lokasi penelitian sebagian besar masih menunjukkan kualitas yang masih layak untuk dikonsumsi oleh masyarakat, kecuali kandungan Fe dan Mn yang tinggi serta NH3-N pada beberapa sumur penduduk akibat pengaruh air permukaan termasuk air banjir masuk ke dalam airtanah.Kata kunci: Kabupaten Serang, kualitas air, kawasan banjir, penyediaan air bersih

Abstract

Ekosistem padang lamun mempunyai fungsi yang sangat penting sebagai stabilitas dan penahan sedimen, mengembangkan sedimentasi, mengurangi dan memperlambat pergerakan gelombang, sebagai daerah feeding, nursery, dan spawning ground. Namun pemanfaatannya ternyata telah menimbulkan permasalahan pencemaran dan mengakibatkan kerusakan. Untuk mengantisipasi permasalahan tersebut digunakanlah fitoplankton sebagai bioindikator, karena beberapa organisme fitoplankton bersifat toleran dan mempunyai respon yang berbeda terhadap perubahan kualitas perairan. Tujuan dari penelitian ini adalah menentukan tingkat kesuburan dan pencemaran air pada ekosistem lamun di perairan Pulau Karimunjawa. Penelitian dilakukan pada 4 stasiun yaitu Ujung Gelam, Legon Lele, Menjangan Besar, dan Cikmas. Berdasarkan hasil penelitian Tingkat kesuburan pada ekosistem lamun di perairan Pulau Karimunjawa berdasarkan bioindikator fitoplankton termasuk dalam kondisi sedang, dengan tingkat pencemaran ringan. Adanya jenis fitoplankton dominan Nitzschia sp dari kelas Bacillariophyceae perlu diantisipasi keberadaannya supaya tidak menimbulkan dampak negatif bagi organisme di dalamnya. Karena fitoplankton jenis ini terbukti menjadi sumber asam domoic (DA) yang beracun dan sangat berbahaya bagi manusia, mamalia laut, dan burung laut.Kata Kunci : bioindikator, fitoplankton, padang lamun
