Abstract

Telah dilakukan penelitian air tanah di sekitar tempat pembuangan akhir (TPA) sampah Bantar Gebang Bekasi menggunakan metode isotop alam (18O, 2H dan 3H) dan dilengkapi data hidrokimia. Penelitian ini dilakukan dengan mengambil sejumlah sampel air lindi, air permukaan dan air tanah di sekitar TPA dengan tujuan untuk melihat sejauh mana pengaruh sanitary landfill terhadap air tanah di sekitarya. Hasil analisis isotop alam menunjukkan bahwa sebagian besar air tanah dangkal telah mengalami kontaminasi oleh zat pencemar yang berasal dari TPA yang sebarannya telah mencapai kira-kira 1 km dari lokasi TPA. Hasil ini didukung dengan data hidrokimia khususnya nitrat yang memperlihatkan kecenderungan yang hampir sama. Sedangkan air tanah akuifer dalam (>40 meter) tidak memperlihatkan adanya pengaruh dari zat pencemar yang berasal dari area TPA.

Abstract

The pipelined water supply services in rural areas of East Java Province in 2004 were 5.5%. This achievement must be improved to reach the Millennium Development Goals (MDGs) target. The target of the MDGs by 2015, is to reduce the proportion of people without sustainable access to safe water supply by 50%. In order to achieve the target, it is necessary to evaluate the constraints which may block the service achievement. This study was conducted in the Brantas River Basin, involving 360 rural water supply systems. Data obtained showed that the water services level in pipeline system in rural areas was only 8.60% in 2005. The achievement of services must be improved up to 40% in 2015, to meet the MDGs target. This target will be achieved if the construction of water supply facilities consider the constraints of poverty and lack of participations. If two constraints above are not controlled, the water supply services achievement will be only 26.2% in 2015.

Abstract

Bio-ethanol is one of fuel alternatives which has several advantages when compared to gasoline. Bio-ethanol has recently been used for blended fuel because of the impact to the emission and engine performance (fuel consumption). It has low emission due to oxygenated fuel as well as high octane number, heat value, and volatility. In this study Bio-ethanol from sugar cane was used in the experiments. For this study, cars with Carburetor and Fuel Injection systems were tested using a chassis dynamometer and run according to the Euro 2 standard which has two cycles, urban cycles and extra urban cycles. Each car was tested three times using different type of blended fuels which were BE 0 (0% of bio-ethanol), BE 5 (5% bio-ethanol) and BE 10 (10% bio-ethanol). The results of the experiments show that emission concentration at Urban Cycle higher than Extra Urban Cycle. Blended fuel with bio-ethanol could reduce emission of Particulate, CO and CO2. Using blended fuel (bio-ethanol-gasoline) also could reduce fuel consumption for both types of cars. The emission reduction can be observed clearly for vehicle with carburetor technology.

Abstract

The municipal solid waste (MSW) generation rate in Kediri was 697,768 m3 per day. The operation period of Kediri’s final disposal site (FDS) is 3-4 years. This condition provides an idea to excavate the FDS as an effort of rehabilitation, and to evaluate the fine material quality as compost. Four sampling sites were selected in the study area: site I (1 m, 3 years old), site II (2 m, 3 years old), site III (1 m, 1 year old), and site IV (2 m, 1 year old). Each sample was separated, air dried, and sieved. The highest fine material component (66,5%) was found in sampling site II. The colour of this fine material was brownish black and the odor was like soil. Characteristics of compost from all sampling sites met the compost quality standard according to SNI 19-7030-2004. Some parameters; however, exceeded the standards. These parameters werer volatile solid (> 80%), carbon (45-47%), C/N ratio (33 – 40), and faecal coli (>1000 MPN/gr). Therefore, the fine material from Kediri’s FDS could not be used as compost. The compost quality was best in FDS age of more than 3 year old and excavated from a depth of more than 2 m.

Abstract

Telah disintesis plastik ramah lingkungan antara polikaprolakton (PCL) dan pati tapioka dengan menggunakan pemlastis alami dari minyak kelapa sawit. Penelitian ini bertujuan untuk mengetahui pengaruh penambahan minyak kelapa sawit, komposisi PCL dan pati tapioka terhadap karakteristik poliblend yang dihasilkan. Untuk mencapai sasaran tersebut, PCL disintesis dari -kaprolakton dan 2,2-dimetil-1,3-propanadiol dengan perbandingan mol 30/1. PCL hasil sintesis dan pati tapioka pada berbagai komposisi diblending secara fisik dan ditambahkan minyak kelapa sawit. Hasil penelitian menunjukkan bahwa PCL dapat disintesis dan struktur molekulnya ditentukan dengan NMR-1H, NMR-13C, dan FTIR. Berdasarkan ilustrasi difraktogram XRD, minyak kelapa sawit dapat menurunkan kristalinitas poliblend pada komposisi tertentu. Viskositas poliblend yang dihasilkan semakin menurun seiring dengan meningkatnya kandungan pati dalam campuran tersebut.

Abstract

Penemuan energi alternatif hangat dibicarakan oleh masyarakat luas karena semakin menipisnya cadangan bahan bakar fosil. Di lain pihak permasalahan sampah kota tak bisa terelakkan. Sampah Kota Surabaya mengandung 72,4% (1560 ton/hari) sampah organik yang mengandung lignoselulosa dan sampah plastik sebesar 10,9% (265,52 ton/hari). Penelitian ini bertujuan untuk menetapkan komposisi dan karakterisasi eko-briket dari sampah plastik campuran dan lignoselulosa. Penelitian ini menggunakan 3 variabel, meliputi sampah plastik campuran, jenis sampah lignoselulosa (serbuk gergaji, sekam padi dan tempurung kelapa) serta ukuran lignoselulosa (40 dan 60 mesh). Parameter uji karakteristik mutu briket meliputi kadar air, kadar Volatile Solid (VS), kadar fixed carbon (FC), kadar abu, dan bulk density, nilai kalor, dan titik nyala. Pengujian parameter tersebut dilakukan di Laboratorium Jurusan Teknik Lingkungan, Teknik Mesin, Teknik Sipil dan Teknik Fisika. Hasil uji menunjukkan bahwa sampah plastik dan lignoselulosa dapat dibuat menjadi ekobriket dengan penambahan lem polyvinyl acetate (PVAc). Produk ekobriket terbaik adalah komposisi 20% plastik campuran dan 80% lignoselulosa tempurung kelapa (M20T40). Karakteristik mutu briket tersebut adalah: kadar air 12,79%, volatile solid 85,14%, fixed carbon 1,56%, kadar abu 0,64%, nilai kalori 8801,04 kalori/gram, bulk density 0,13 gram/cm3, dan titik nyala 131,8oC. Hasil tersebut sesuai dengan baku mutu Permen ESDM No. 47 tahun 2006 dan mampu dijadikan salah satu alternatif pemenuhan keterbatasan energi Indonesia.

Abstract

The aim of this research was to model the flood discharge estimation caused by landuse change by using Geographical Information System (GIS). The research was conducted from May to August 2006 in Lesti Hulu watershed. The methods included three steps, comprising data (spatial and attribute) gathering in year 2000 and 2004, data processing, and validity test. The validity test was conducted using SIMODAS-ITB software. The biggest change was settlement areas that increase 9.21 %. The flood peaks n the same rainfall condition of 92.22 mm were 202.54 m3/sec in year 2000 and 208.66 m3/sec in year 2004. The model used in this research had a high accuracy. This statement was espoused by a simulated hydrograph, which was almost similar to observed hydrograph; with R2 values of 86.22% and 72.02% in years 2000 and 2004 respectively. The rational test showed that the ratio between direct v value of 2.402.775 m3 and modeled v value of 2.385.081,6 m3 was 0.993. This meant that the mathematical model for determining flood discharge using SIMODAS-ITB software was valid, and provided an accurate output.

Abstract

Life Cycle Management (LCM) is a framework of concepts, techniques and procedures concerned to an environmental management of products and organizations in achieving continuous environmental improvement viewed from life cycle perspective. One tool in LCM approach is Life Cycle Assessment (LCA) which consists of a method to quantify environmental impacts associated to products or activities throughout their life cycle, begins with extraction of raw materials, proceeds through production and use, ends to waste treatment (from cradle to grave). This research deals with analysis of LCA for products of Fluorescent Lamp of 20 Watt. The research question exposed is how to evaluate the best alternative to improve environmental performance among many strategies designed on LCA results. Due to in the real system, environmental consideration is not the only one criteria used for decision making, this research proposes to takes into account for multi criteria evaluation in selection of the best strategy such as criteria of investment cost, corporate image etc, to do so the method of AHP (Analytical Hierarchy Process) is proposed to apply. In order to evaluate the environmental impact associated the process throughout the life cycle the product, existing database built in SimaPro-5 software. This research concludes that the strategy of “product take back” principle is the best solution in order to achieve the optimal environmental performance.

Abstract

The generation of plastic wastes in Bandung’s society is about 86300.37 kg/day. The reduced amount of it is only a few. The aim of this research is to determine the recycling infrastructure capacity in Bandung City. This research used interview and observation methods. Capture rate of plastic waste in Bandung is 41,55% from all plastic waste that generated by Bandung’s City, it means recycling activity of plastic waste has not yet reached its full potential because the sources don’t do separation. The capacity of infrastructures that are built for each location wilayah (Bandung Barat, Bandung Tengah and Bandung Timur), by making an assumption that it is 100% optimized, are 150,25 m3/day, 321,35 m3/day, and 141.49 m3/day. While by making assumptions, for 50% optimized and 60% optimized, the capacity of infrastructure in West Bandung and East Bandung are 0 m3/day and 0 m3/day, because the available infrastructure is enough. For Central Bandung are 14589,61 m3/day (50% optimized) and 24083,77 m3/day (60% optimized).

Abstract

Kabupaten Jember terletak pada ketinggian kurang lebih 89 meter dari permukaan air laut dengan luas area 9.897,83 Ha (BPS Jember, 2005). Jumlah penduduk di Kabupaten Jember adalah 2141467 jiwa, dengan pertumbuhan penduduk + 0,71% per tahun. Kepadatan penduduk di wilayah perkotaan cukup tinggi yaitu rata-rata 3767 jiwa/km2. Sebagian peduduk di perkotaan Jember bertempat tinggal di kawasan permukiman padat yang cenderung memiliki lingkungan yang kurang terpelihara dan penyediaan prasarana dasar yang terbatas. Penelitian ini memaparkan isu ketersediaan prasarana air bersih dan sanitasi serta memaparkan model pengelolaannya. Pemecahan masalah ketersediaan prasarana dasar permukiman perkotaan yang padat adalah meningkatkan partisipasi masyarakat, sehingga tumbuh kesadaran akan pentingnya kesehatan dan kualitas lingkungan. Upaya penyediaan prasarana air bersih dan sanitasi yang sesuai kebutuhan merupakan hal yang sangat penting untuk mencegah pencemaran lingkungan. Untuk itu, strategi dan langkah yang tepat sebaiknya bertumpu pada masyarakat guna peningkatan pelayanan air bersih dan sanitasi.
