Abstract

Banjir tanggal 11 Februari 2002 mengejutkan banyak pihak karenadatangnya 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 GubernurDKI yang mengatur tentang sumur resapan, pelaksanaan dilapangan masihsulit 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.

Abstract

Anaerobic digestion of organic waste has some advantages, namelythe recovery of biogas as alternative energy source and the conversionof waste products to soil fertilizer. Compared to mesophilic digestion,thermophilic digestion offers advantages regarding the processperformance and the hygienic aspect. Unfortunately, the process hasgenerally not enjoyed a good reputation because of its poor record withrespect to process stability. Two-stage anaerobic reactor systemconsisting of a hydrolysis reactor and a methane reactor is often usedto overcome such instability problems. In this study, the two-stageanaerobic reactor system is compared to the one-stage anaerobic reactorsystem. This study shows that the two-stage anaerobic reactor systemhas more process stability, can be operated at much more higher organicloading rate, and need much shorter recovery time after a processfailure.

Abstract

Dalam upaya mengurangi ketergantungan terhadap bahan bakar fosil terutama bahan bakar minyak (BBM), Pemerintah Indonesia menargetkan penggunan bahan bakar nabati (BBN) seperti bioetanol dan biodiesel sebanyak 5% pada tahun 2025. Kendala utama dalam hal pengembangan BBN ini adalahadanya kompetisi bahan baku BBN dengan penyediaan bahan pangan, keterbatasan dalam hal sarana dan prasarana serta kendala non teknis lainnya misalnya berupa fluktuasi harga minyak mentah dunia. Bila kondisi harga minyak mentah dunia naik, maka kondisi ini akan mendorong upayadiversifikasi energi, demikian pula sebaliknya. Pada penelitian ini, dilakukan perhitungan produktifitas BBN biodiesel mikroalga dengan membandingkan harga produksinya dengan harga minyak mentah dunia. Mengacu pada hasil perbandingan biaya produksi mikroalga dengan harga minyak mentah jugadianalisis upaya peningkatan nilai profitabilitas biodiesel mikroalga dengan meningkatkan efisiensi produktivitas melalui pemanfaatan limbah sebagai input produksi dan meningkatkan produk tambahan, serta penambahan inovasi produksi dengan pemanfaatan limbah dan penganekaragaman produk. Hasilperhitungan menyatakan bahwa pada kondisi harga minyak mentah sebesar 70 US$/barel maka biaya produksi bahan baku minyak alga tidak boleh lebih dari Rp. 6.180,-/liter. Penambahan inovasi produksi dengan pemanfaatan limbah dan penganekaragaman produk dapat meningkatkan profitabilitas sebesar 14,2% dan 30,5% atau menurunkan biaya produksi biodiesel dari Rp. 9.025,-/liter menjadi Rp.6.270,/liter.

Abstract

The renewable energy generally can support or trigger the economic growth in household utilization, and give rise to the opportunity for people (men or women) in rural areas to run small scale home industry. The introduction of renewable energy in rural areas will significantly transform the social, cultural and economic structure from traditional style to modern (western) one. The structural transformation will force all people to be drawn in. Many benefits can be gained if women participate in the transformation.This paper describes the impacts which will take place during the structural transformation in rural areas, in general, and women participation in particular. This will greatly determine the accomplishment in the policy and implementation of technology adaptation in renewable energy field.

Abstract

ABSTRACTPademawu Sub-District consist of salt ponds reached 740.96 Ha that is the second largest area in Pamekasan. Land-use overlapping problems between salt ponds and settlement influence the environmental degradation enhancement. The presence of salt ponds is indicated as the cause of increased salinity in well-water around the settlement so that the well-water is salty. To determine the influence of salt pond on groundwater pollution, the information regarding surface characteristics as well as the profile beneath the surface is essential. The method consisted of a hydro-geology survey, hydrochemistry, and geophysics (Geo-Electricity method). The type of groundwater is predominated by chloride (Na-Cl) and carbonate (Na-HCO3, Ca-HCO3). Based on groundwater chemistry element calculation, it is observed that there is an influence of salt pond infiltration on groundwater aquifer. The conductivity of groundwater ranged from 15,000–50,000 µS/cm (categorized into salty water). The specific resistance value of rocks beneath the surface varied between 0.1–300 that is usual in either coastal or alluvial area. The low value of specific resistance associated with alluvial lithology consisted of either brackish water or salt water expected the result of salt pond filtration. The depth of surface saltwater contaminating the aquifer layer ranged from 5 up to 30 meters. The presence of salt ponds influences the level of contamination of Cl- pollutant in shallow groundwater in Pademawu Sub-District, Madura, so it is necessary to re-arrange the land-use system in the coastal area.Keyword: groundwater pollution, salt pond, Pademawu Sub-District, Specific resistance Geo-ElectricityABSTRAK Kecamatan Pademawu terdiri atas kawasan tambak garam seluas 740,96 Ha yang merupakan wilayah terluas kedua di Pamekasan. Pemasalahan tumpang tindih jenis pemanfaatan lahan tambak garam dengan lahan pemukiman berpengaruh terhadap peningkatan degradasi lingkungan. Keberadaan tambak garam diindikasikan sebagai penyebab meningkatnya kadar salinitas pada air sumur di sekitar pemukiman sehingga air sumur terasa asin. Untuk mengetahui pengaruh keberadaan tambak garam terhadap pencemaran air tanah, dibutuhkan informasi mengenai karakteristik permukaan maupun profil bawah permukaan. Metode penelitian yang dipakai terdiri atas survei hidrogeologi, hidrokimia dan geofisika (metode geolistrik). Tipe air tanah didominasi oleh tipe klorida (Na-Cl) dan karbonat (Na-HCO3,Ca-HCO3), hasil perhitungan rasio unsur kimia air tanah menunjukkan adanya pengaruh infiltrasi air tambak garam kedalam akuifer air tanah. Nilai DHL air tanah daerah penelitian didominasi nilai dengan kisaran 15.000–50.000 µS/cm dan masuk dalam sifat air asin. Nilai tahanan jenis batuan bawah permukaan bervariasi antara 0,1–300 Ωm yang umum dimiliki pada kawasan pesisir atau alluvial. Nilai tahanan jenis rendah berasosiasi dengan litologi alluvial yang terdiri atas air payau atau air asin yang diduga hasil infiltrasi dari air tambak garam. Kedalaman muka air asin yang mencemari lapisan akuifer berada pada kisaran kedalaman 5 hingga 30 m. Keberadaan tambak garam memberi pengaruh terhadap tingkat pencemaran polutan Cl- pada air tanah dangkal yang ada di Kecamatan Pademawu, Madura, sehingga dibutuhkan penataan ulang sistem tata guna lahan di kawasan pesisir tersebut.Kata kunci: pencemaran air tanah, tambak garam, Kecamatan Pademawu, Geolistrik tahanan jenis
