| 81 | Penurunan Kadar Krom (Cr) Dengan Menggunakan Biomasa Ampas Tebu Secara Bio-Adsorbsi | Chrome is a substance belong to high toxicity heavy metal group which can cause both acute and chronic poisoning. One of the methods that can be used to reduce its concentration is biosorbtion with bagasse biomass. The objectives of the study were to understand the chrome concentration before and after absorbed, as well as to understand the amount of the most effective biomass. The study was an experimental with three treatments of which consisted of eight repetitions. The sample was synthetic liquid waste and the treatment absorbent was bagasse biomass which was processed as activated carbon of 10, 15, and 20 grams weight. The chrome concentration were measured by using AAS method. The results showed that the chrome concentration before treated was 10,196 mg/l, and the average of the reduction from the three absorbents weight were: 0.174 mg/l, 0,099 mg/l, and 0,011 mg/l respectively. It can be concluded that there were reduction differences amongst the three treatments, and 20 gr absorbent was the most effective one (99.88 % reduction). It is advised for further study to apply the bagasse for processing liquid waste from industrial activities. | Bagasse biomass, Chrome | Yasril, Heru Subaris Kasjono, dan Sri Puji Ganefati | |
| 82 | Pengaruh Bahan Pengkondisi Tanah Terhadap Iklim Mikro Pada Lahan Berpasir | Usahatani pada lahan berpasir akan dijumpai banyak kendala yang berhubungan dengan kondisi fisik tanah, hidrologi tanah dan iklim, lebih khusus lagi kondisi iklim mikro yang kadang kurang kondusif untuk pertumbuhan tanaman. Oleh karena itu perlu adanya terobosan guna melakukan rekayasa lingkungan, agar supaya keadaan yang kurang menguntungan tersebut dapat dimanfaatkan secara optimal oleh petani, yaitu melalui masukan teknologi alternatif berupa penambahan bahan pengkondisi tanah (pupuk kompos, pupuk kandang, biomikro), pembuatan jaringan irigasi dan pembuatan pelindung/naungan yang pada hakekatnya berfungsi untuk mengurangi fluktuasi suhu harian pada tanah (intensitas matahari), penurunan penguapan dan kehilangan air (evaporasi). | Bahan Pengkondisi Tanah, Iklim Mikro, Intensitas Matahari | Sudaryono | |
| 83 | Pengaruh Logam Dan Konsentrasi Substrat Terhadap Pertumbuhan Dan Aktivitas Bakteri Proteolitik ? | Dalam penelitian ini telah dilakukan penelitian untuk mengetahui pengaruh penambahan ion-ion logam di dalam media padat terhadap pertumbuhan bakteri 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. | Bakteri protease, aktivitas proteolitik, isolat cangkang udang, ion logam, substrat protein | Joko Prayitno Susanto dan Nida Sopiah | |

| 86 | Pemanfaatan Limbah Tanaman Pisang Untuk Memproduksi Gula Melalui Proses sakarifikasi | Banana is a major cash crop of the tropical region generating vast agriculture waste after harvest. The agrowaste including dried leaves and pseudostem after harvest was used as substrate for the release of sugars. Saccharification of banana agrowaste by cellulases of Trichoderma lignorum was investigated. The steam treated agro-waste yielded 1,34 mg/ml of reducing sugars after 24 hours fermented. The size of substrate affected saccharification where the smaller size (< 120 micron) yield more sugars. Maximum sugars were released at pH 6,0 whereas 40 0C was the optimum temperature. Thus, under these conditions the agrowaste left behind for natural degradation can be utilized affectively to yield fermentable sugars which can be coverted into other substances like alcohol. | Banana agrowaste, Trichoderma lignorum, cellulases, sacc | Donowati Tjokrokusumo | |
| 87 | Penanggulangan Banjir Dengan Jaring Pengaman Sosial Sumur Resapan Di Jakarta Dan Sekitarnya | Banjir tanggal 11 Februari 2002 mengejutkan banyak pihak karena datangnya tiba-tiba dan tidak terduga besarnya, sehingga hampir 30% wilayah Jakarta tergenang air , transportasi lumpuh , dan memakan korban jiwa akibat tanah lingsor, tenggelam, hanyut dan tersengat aliran listrik. Total aliran air permukaan diperkirakan mencapai 70 juta meter kubik, dimana jumlah tersebut tidak dapat tertampung oleh badan-badan sungai yang ada dan meluap menggenangi daerah dataran banjir sungai (floodplain area) yang saat ini banyak ditempati oleh pemukiman penduduk. Berdasarkan hasil studi yang dilakukan oleh Kelompok Pengkajian Sitem Pengelolaan Air (BPPT) dalam Studi Studi Model Optimisasi Pengelolaan Air Tanah Jakarta, maka besarnya imbuhan buatan yang harus dimasukkan kembali kedalam akuifer dangkal untuk daerah seluas 25 km2 berkisar antara 1.082.419- 54.120.960 m3/tahun atau antara 1,08 - 54,12 m3/tahun/m2. Lokasi imbuhan buatan dapat dilihat pada Peta Lokasi Imbuhan Buatan Berdasarkan Hasil Optimisasi Pengelolaan Air Tanah. Jika diasumsikan 1 (satu) sumur resapan dengan diameter 0,8 meter, lebar bidang resapan 1 meter pada tanah dengan permeabilitas rendah (0,00105 m/hari), maka kapasitas sumur resapan adalah 0,592 m3/tahun/unit. Dengan demikian untuk daerah Jakarta dan sekitarnya dibutuhkan kurang lebih 2 juta sumur resapan. Pelestarian lingkungan merupakan tanggung jawab pemerintah dan masyarakat. Walaupun sudah ada Surat Keputusan Gubernur DKI yang mengatur tentang sumur resapan, pelaksanaan dilapangan masih sulit pengawasannya. Dalam kondisi krismon ini perlu langkah terobosan untuk membuat sumur resapan dengan program jaring pengaman sosial, dengan demikian pemerintah membuka lapangan pekerjaan bersamaan dengan perbaikan lingkungan. | Banjir, air tanah, sumur resapan | R.

| 88 | Penghilangan Bau Secara Biologi Dengan Biofilter Sintetik | Biofilter as one of method processing of waste have been introduced since early 20, but in its application have time to be left by effect of newer technological appearance like trickling filter, rotating biological contactor, activated sludge, and fluidized bed reactor. Biofilter very effective in deodorizing, especially dangerous aromas of organic volatile compound, and poisonous air from industry with efficiency 90 - 99,9%. Biofiltrasion become more economic compared to carbon adsorption or oxidation when its organic content under 3000 ppm. Most biofilter operate on organic concentration around 1000 ppm or lower. There are some matter to influence market of biofilter, for example : 1). the increasing of regulation about oxide nitrogen emission coming from hot process. Biofilter do not yield nitrogen oxide addition, 2). The increasing of sigh of society about contamination of aroma of facility processing of waste, processing of solid waste and others, 3). preventive methodologies implementation of pollution using condensation and air emission concentration, 4). Pressure to industry to use processes with discard as small as possible, 5). The increasing of attention to emission of hit and organic air materials, and also low cost water treatment technology | Bau, Odour, Biofilter, Biofilm, Limbah tahu dan tempe, wastewater treatment | Arie Herlambang | |
| 89 | Analisis Vegetasi Pada Habitat Rusa Bawean (Axis Kuhlii Mull. Et. Schleg) Di Pulau Bawean | Bawean Island is a remote and tiny island, located approximately 150 km north of Surabaya. In this island it is known to habituate an endemic deer called Bawean deer (Axis kuhlii Mull. Et. Schleg). The animal is protected both nationally and internationally. Understanding the forest as the habitat for this deer is an important step toward the management and the development of the whole habitat. This study was conducted on September 2001 in three locations, known to be the habitat for Bawean deer, that was the Kumalasa, Patarselamat and Pudakit Barat villages. The forest type at study sites was lowland secondary forest. There were 114 species from 90 genus and 56 families. Number of species and trees density at Audacity Barat villages are bigger than Patarselamat or Kumalasa villages. In all study sites, Syzygium lepidocarpa, Irvingia malayana, Garcinia dioica, and Microcos tomentosa are common species.Trees height in three location were under 25 m tall, and stem diameter class were highest among 10-20 cm. Species richness (Ss) ranged from 22,7 to 55,7%.

| 90 | Produksi dan Formulasi Bioinsektida dan Propagul Aktif Jamur Beauveriabassiana | Tondano is a natural and biggest lake in North Sulawesi which some strategic functions i.e for irrigation, source of drinking water, hydropower, freshwater culture, tourisms, overflow control. Wide of Tondano Lake is about 46 ? 51 km2. There are 35 streams as inlet and one outlet only is Tondano Stream. Tondano Lake has some problems caused by many activities both in downstream area or around of the lake. People?s activities such as land clearing for plantation in downstream area, freshwater culture and daily people?s activities around of the lake had been organic material contribution in the lake waters. It has caused of water hyacinth booming (Eichornia crassipes (Malt) (Soms), erosion and sedimentation. Nowadays water hyacinth has been covered about 20% of Tondano Lake?s wide. Besides reduce of waters quality, water hyacinth booming has been made problems for hydropower and traffic in lake waters to the outlet. Because of that problems, Tondano Lake needs concern for intensif management. | Beauveria bassiana, bionsecticide, production technology, formulation | Untung Suwahyono dan Priyo Wahyudi | |
| 91 | Beban Pencemaran Limbah Industri dan Status Kualitas Air Sungai Citarum. | Sungai Citarum beserta tiga waduk besar yaitu Saguling Cirata dan Juanda (Jatiluhur) memiliki fungsi ekonomi ekologi dan sosial yang sangat penting bagi masyarakat Jawa Barat dan DKI Jakarta. Potensi yang demikian pentingnya tersebut terancam oleh penurunan kualitas air sungai karena beban pencemaran yang terus meningkat telah melampaui daya tampung sumber air tersebut. Beban pencemaran terbesar berasal dari limbah penduduk dan industri sehingga memerlukan prioritas penanganan utama dalam upaya pengendalian pencemaran air. Meskipun PROKASIH telah berhasil menurunkan beban pencemaran limbah industri,namun kualitas air Sungai Citarum sejak PROKASIH tahun 1989 sampai saat ini belum menunjukkan perbaikan, bahkan cenderung memburuk. Status kualitas air Sungai Citarum sejak tahun 1989 sampai saat ini tidak pernah memenuhi Baku Mutu Air yang telah ditetapkan Pemerintah Daerah sepanjang tahun.Berdasarkan hasil simulasi model kualitas air pada sub. DPS Citarum Hulu, untuk memulihkan kualitas air sungai Citarum Hulu sampai mjemenuhi Baku Mutu Air yang ditetapkan sepanjang tahun, diperlukan pengurangan beban pencemaran organik (BOD) sebesar 85%. Oleh karena itu pengolahan limbah industri saja tidak cukup, sehingga pengolahan limbah domestik dari pemukiman harus dilakukan secara bersamaan. Selain itu diperlukan upaya peningkatan daya tampung sungai melalui upaya konservari daerah tangkapan air pada DPS Citarum. Berdasarkan hasil penelitian terdahulu, pembangunan sistem Pengumpulan dan Pengolahan Limbah Industri Terpusat (SPPLIT) pada sejumlah zona-zona (cluster) industri pada DPS Citarum merupakan kebijaksanaan strategis untuk menurunkan beban pencemaran limbah industri. Disamping itu upaya pemulihan kualitas air Sungai Citarum perlu ditunjang dengan upaya penegakan hukum yang konsekwen, serta komitmen semua pihak yang berkepentingan untuk melaksanakan upaya pengendalian pencemaran air yang telah direncanakan secara nyata dan konsisten. | Beban Pencemaran, Pencemaran Air, Model Kualitas Air | Nana Terangna Bukit dan Iskandar A.

| 92 | Pendekatan Ekonomi Dlm Pengembangan Suatu Metodologi Utk Perkebunan Energi Pd Lahan Kritis | As a result of population pressure, deforestation in Java has increased considerably that causes an increase on critical land. The situation is worsened by increasing of kerosene and diesel prices that causes to an increase on fuelwood utilization that would lead to increase of illegal cutting. The increase of critical land could lead to increase of soil erosion, landslide, and flood as a result of a reduction in water absorption and soil retention. The Department of Forestry has initiated a reforestation program to ameliorate the situation. However, as the limited budget, the economics of the program needs to be examined further. Based on benefit-cost ratios, economic contributions of the fuelwood component indicated that the reforestation program or energy plantation was economically unfeasible. However, by including benefits of soil erosion control the program was economically attractive on some sites. A methodology was developed to prioritize which critical land to reforest. This was applied by identifying market price of fuelwood at minimum yield that would justify an energy plantation investment. The method indicated that subject to budget availability, critical lands should be reforested in descending order of productive potential until the site of minimum yields is reached. | benefit-cost ratio, biomasa, perkebunan energi, lahan kritis | Endang Suarna | |
| 93 | Asas Kota Berkelanjutan Dan Penerapannya Di Indonesia | Cities percieved having strategic role for implementing global program on sustainable development as established through Earth Summit at Rio de Janeiro by 1992. It is realized that cities are fundamental for economic opportunities and social interaction, as well as cultural and spiritual enrichment. However, cities also damage the natural environment and exploit natural resources in an unsustainable manner, which can jeopardize long-term prosperity and social wellbeing. This is of global concern, as more than half of the world?s population lives in cities and trends indicate that this will increase. Based on this understanding by 1994 European cities declared Aalborg principles and by 2002 several cities of the world declared Melbourne principles on sustainable cities. The principles are intended to guide thinking and provide a strategic framework for action and allow cities to develop sustainable solutions that are relevant to their particular circumstances. Despite there were Indonesian cities participate in Melbourne conference, sustainable cities is still aliens for most of city governance. Therefor there was initiative to formulate sustainable cities principles that assumed more relevance and appropriate to Indonesian situation. | berkelanjutan, kota, asas, kota berkelanjutan | Tjuk Kuswartojo | |
| 94 | Aplikasi Bio-Ball Untuk Media Biofilter Studi Kasus Pengolahan Air Limbah Pencucian Jean | The textile industry is one of the most popular industries in Indonesia. Although it?s giving a positive value towards economic value, it also contributes a bed effect towards environmental quality. One of those industries is small-scale laundry industry located in Kelurahan Sukabumi Selatan, West of Jakarta. The lack of land and money, most of the jeans laundry industry throws away their wastewater straight to the river system without any process. The present study describes the application plastic media called bio-ball as a biofilter supporting media for treating of jeans laundry industry wastewater using combined anaerobic and aerobic process. The type of reactor that is used in this research is a continuous flow biological reactor which has total volume 195 litter and divided into 5 zones, i.e. presedimentation , 2 anoxic zone, aerobic zone and post sedimentation zone. Reactor effluent is recirculated into presedimentation zone with hydraulic recycle ratio (HRR) 1:1. Seeding is done in a natural way by directly flowing the domestic wastewater into reactor with retention time 72 hours, until a biofilm layer is formed on the surface of bio-ball media. Acclimatization is done gradually by replacing domestic with laundry jeans wastewater in 72 hours retention time, until domestic wastewater was 100 % replaced, The main research were conducting by continuous operation under condition 72 hours, 48 hours and 24 hours retention time. The result of experiment shows that within the combined anaerobic and aerobic process using bio-ball plastic media under conditions 1 - 3 days retention time, the removal efficiency of COD 78 ? 91 %, BOD 85 ? 92 %, Total Suspended Solids (TSS) 80 ? 93 %, and Colour 48 ? 57 % respectively. The longer retention time has resulted in higher removal efficiency. | Bio-ball, biofilter, pencucian jean, anaerob-aerob. | Nusa Idaman Said | |

However, some of people in Indonesia have not been realized that uneconomic values and unnutritious of agro materials could be converted into high value of food and feed, and also usefull material for soil conditioner which is improved soil health. In addition, spent mushroom substrate as a waste of mushroom production can be used for a stater material to remediate contaminated soil as one of the strong capability material for bioremediation technology for polluted environment. Therefore, this review would like to create some hopes for pheasant to covert some agricultural waste materials into useful materials toward poverty alleviation and sustainable community development as mentioned by millennium development goals. Through this application of bioconversion and bioremediation technology of agricultural waste which is ubicuitous in tropical countries like Indonesia, we do much more for environmental care and social welfare | bioconversion technology, agricultural waste, healthy food, soil conditioner | Sabaruddin Wagiman Tjokrokusumo | |
| 96 | Studi Efek Penggunaan Biodisel Terhadap Emisi ada Sektor Transportasi di Jakarta | Biodiesel has been proven by world wide numerous studies as an environmental friendly alternative diesel fuel. Biodiesel is essentially sulfur free. Engines fueled by biodiesel emit significantly fewer particulates, hydrocarbons and less carbon monoxide than that operating conventional diesel fuel. The maximum utilization of biodiesel in Indonesia could improve the air quality level in major cities especially in Jakarta. The objective of this study is to assess the effect of biodiesel utilization in transportation sector to the air pollution level in Jakarta. The targeted emission in the study are carbon monoxide (CO), nitrogen oxides (NOx), hydrocarbons (HC), sulfur oxides (SOx) and particulate matter (PM) from vehicle sources. The scenarios used in this study are the utilization of B10 in 2010 and increased to B20 in 2015, B30 in 2020 and B50 in 2025 as an automotive diesel fuel substitution in Jakarta. The result showed that the utilization of biodiesel could improve the air quality level in Jakarta, especially on SO2 and PM emission. By using B10 in 2010, the emission of SO2 and PM will decrease 7,95% (2.070 ton) and 15,62% (1.680 ton) respectively compared to utilizing of pure fossil automotive diesel oil. The highest emission improvement was shown on B50 in 2025 scenario. The reduction of SO2 and PM was reached 35,69% (16.660 ton) and 23,21% (4.360 ton) respectively. | biodiesel, emission, air quality | Soni S. Wirawan1, Armansyah H.
