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.

University campuses generate large amount of various types and components of solid wastes. Among the types are municipal solid waste like, laboratory waste, and e-waste. Unfortunately, not many universities have considered the solid wastes as resources. The unseen recovery and recycling potentials of the campus solid wastes has made them to be disposed of without significant reduction efforts. This paper discusses a concept on building-up a sustainable integrated solid waste management in university campus, which covers policy-plan-do-check-action-continual improvement stages. Examples of successful implementation of integrated solid waste management in some universities are also discussed.

Water hyacinth (Eicchornia crassipes) has high cellulose and hemicellulose contents and low lignin content. Therefore, water hyacinth biomass is very potential to be used as raw material for bioenergy production. This water weed is commonly found in eutrophied rivers and water channels, or harvested from waste water treatpent lagoons. This research is aimed to collect data and information on water hyacinth potential in producing bioenergy in the forms of biogas. This research is also aimed to determine the optimum condition for biogas productions, particularly the pretreatment methods and water hyacinth slurry and biostarter ratios. Research on biogas production was initiated by testing two types of biostarters. The intestine of terestrial snail and cow faeces were applied in different anaerobic reactors, which contained water hyacinth slurry. The best biostarter was selected for biogas production in anaerobic reactors at different water hyacinth slurry and biostarter ratios of 75/25, 50/50, and 25/75. Control reactors, which contained water hyacinth slurry, and other control reactors, which contained biostarter solution, also prepared. Optimum condition which can be recommended for biogas production from water hyacinth is as follows: water hyacinth slurry with COD value of 5000-6000 mg/L is mixed with cow faeces at water hyacinth slurry and biostarter ratio of 75/25, and retention time of 20 days.

EVALUASI KELAYAKAN ASH VALLEY PLTU SURALAYA SEBAGAI SECURE LANDFILL Yulinah Trihadiningrum

Pembangkit Listrik Tenaga Uap (PLTU) Suralaya, Jawa Barat menggunakan batu bara sebagai bahan bakar. Sisa dari proses pembakaran batubara berupa abu terbang (75%) dan abu dasar (20%). Uji TCLP dilakukan terhadap abu terbang yang berasal dari Bukit Asam dan Kalimantan, abu dasar dan abu campuran pada landfill, dengan tiga parameter pengujian, yaitu Pb, Zn dan Cu. Semua hasil nilai uji masih berada di bawah baku mutu TCLP, sehingga limbah abu batubara dinyatakan bukan B3. Hasil pengujian kualitas lindi pada settling pond menunjukkan bahwa settling pond kedua mengandung Total Dissolved Solid (TDS) tertinggi, yaitu sebesar 1120 mg/l dan telah melampaui baku mutu limbah cair untuk kegiatan industri yang tertera pada KEP-51/MENLH/10/1995.

Penetapan jalur alternatif sistem transportasi sampah diperlukan agar dapat mendukung sistem pengangkutan sampah ke Tempat Pembuangan Akhir (TPA). Hasil pengolahan data yang diperoleh berdasarkan analisis hirarki (Analytical Hie-rarchy Process), terhadap masing-masing kriteria tersebut adalah sebagai berikut, yaitu : kriteria ekonomis (0,528), kri-teria teknis (0,333), dan kriteria fisik (0,140). Masing-masing hasil pembobotan dari ketiga kriteria tersebut diberi pem-bobotan prioritas terhadap subkriteria-subkriteria dari 2 zona wilayah yang merupakan jalur alternatif pengangkutan sampah ke lokasi TPA. Dari hasil pembobotan tersebut, diperoleh bobot prioritas terbesar pada zona I (Kecamatan Wo-lio) senilai 0,640.

This research was aimed to determine the level of Surabaya river pollution according gills degradation of tawes (Puntius javanicus, BlKr.) and nila (Oreochromis niloticus) as well as melanophora pattern of fish scales. Weekly observations of some physicochemical parameter were pH, temperature, DO, COD, SS and biological parameter (respiration rate and melanophora pattern). The Prati Index the pollution level of Surabaya river in Bambe station was higher (polluted, class IV) than Cangkir station and Karangpilang station (good, class II). Results of gills observation showed that the pollution level in Bambe was higher (gills degradation level 4) than in Cangkir station and Karangpilang station (gills degradation level 3)
