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)

SLAUGHTER HOUSE SOLID WASTE MANAGEMENT IN INDONESIA Rhenny Ratnawati; Yulinah Trihadiningrum

he solid slaughter house waste (SSW) in Indonesia is generally disposed of into open dumped landfill. This type of solid waste can cause odor and atmospheric pollution if discharged directly into the environment. Additionally, it may spread disease due to the nesting vectors, and the resulting leachate can lead to groundwater contamination. This paper reviews the characterization of slaughter house (SH) types and SSW generation potential and to review the development of treatment technology of SSW and its application. The SH in Indonesia is divided into 3 classes, namely: 1) SH for large and small ruminants; 2) SH for poultry; 3) SH for pigs. Application technologies in Indonesia include compost and biogas technologies, and the use of rumen content for animal feed. Problem in biogas technology is generally caused by the high nitrogen content in the SSW. The most suitable raw material for biogas production is herbivore waste. The main advantages of using SSW for compost production are: the appropriate characteristics for composting process, free of hazardous contaminant, and appropriate composting technologies are available to reduce environmental problems caused by SSW. In addition, rumen content is considered to be a potential alternative for animal feed because have high content of amino acids (approximately 73.4% of the total protein) and rich in vitamin B complex. Among the disadvantages, the composting process of SSW requires long time period and generate air pollutants, such as ammonia and hydrogen sulphide.

Phanerochaete chrysosporium was known as white rot mold which could biodegrade persistent organic pollutants. In this research the ability of the mold in biodegrading textile dye direct orange S and rhemazol yellow, which contained naphtol functional group, was studied. This research included characterization of the waste water and determination of optimum concentration of the waste water for biodegradation. The optimum concentration for biodegradation was determined by measuring the radial growth of the mold in agar medium containing various concentrations of textile dye. The final stage was the application of the mold for biodegrading the textile dye in aerobic batch reactor using the selected concentration. This research showed that P. chrysosporium could grow satisfactorily in minimum medium containing synthetic textile wastewater in various concentrations. The highest colour removal efficiency of 93% was achieved in 3 days in the waste water with highest color intensity (absorbance value l520 = 4.00), and 48% in the waste water with absorbance value l520 = 1.22. COD removal efficiency of 87% was achieved within 12 days in the wastewater of 30% concentration, and 83% in the waste water of 100% concentration. The pH values decreased to 3.23 in the waste water with lower dye concentration and to 3.42 in the higher color intensity, from the initial values of 5.0-6.0. This research concluded that P. chrysosporium was capable to biodegrade naphtol textile dye with reasonably high efficiency.

Pemerintah Kabupaten Sidoarjo membangun TPST Lingkar Timur yang beroperasi sejak 12 Desember 2015. TPST tersebut melayani sebagian besar sampah di Kecamatan Sidoarjo, Candi, dan Buduran dengan total 6.510 KK. Kondisi yang ada di TPST ini masih belum sesuai dengan Permen PU nomor 03/PRT/M/2013, karena belum memiliki zona penyangga, sistem pengendalian pencemaran lingkungan, dan instalasi pengolahan. Selain itu, belum ada tempat untuk menyimpan sampah terpilah. Penelitian ini bertujuan untuk mengukur kuantitas dan komposisi sampah yang diolah di TPST, mengevaluasi kondisi eksisting pengelolaan sampah di TPST Lingkar Timur, dan merencanakan ulang desain dan optimasi pengelolaan sampah di TPST, meliputi dari aspek teknis dan finansial. Perencanaan diawali dengan kegiatan survei dan sampling untuk mendapatkan data berupa kuantitas sampah yang ditangani, data komposisi sampah, densitas sampah, potensi daur ulang sampah, juga kondisi sarana serta prasarana yang ada. Hasil penelitian menunjukkan komposisi sampah terdiri dari sisa makanan dan kebun (44,6%), plastik (30,92%), kardus/karton (9,82%), kain (1,90%), kaca (1,16%), logam (0,60%),karet/kulit 0,44%, B3 rumah tangga (0,2%) dan lain-lain (10,37%). Selain itu terdapat fasilitas lain yang tidak tercatat pada Permen PU nomor 03/PRT/M/2013 yaitu fasilitas berupa kamar tidur, dapur, dan warung. Optimasi pengelolaan sampah dilakukan dengan hanya mengolah jenis sampah kering (plastik, kaca, logam, karet/kulit). Pemilahan dilakukan dengan kecepatan 80 kg/jam/orang agar mencapai nilai reduksi hingga 35,82%, dan memenuhi target pengurangan sampah Jakstrada Kabupaten Sidoarjo tahun 2025. Luas lahan optimasi yang dibutuhkan yaitu 2.931,4 m2 dengan tenaga kerja berjumlah 50 orang. Lahan yang ada, dapat melayani sampah hingga 6.825 KK dan 36 fasilitas umum. Biaya investasi yang dibutuhkan yaitu Rp 1.157.344.970 dan biaya operasional Rp 2.287.316.928/tahun. Potensi pemasukan dari penjualan dan retribusi yaitu Rp 306.152.422/bulan. Dengan metode NPV proyek redesain ini dianggap layak secara finansial.

The electroplating industry produces wastewater containing heavy metals. The high surface area of bacteria has the potency to reduce heavy metals content in wastewater since it has ability to absorb the metals. This study aims to find out the bacterial DNA profile after Cd bioremoval process using Bacillus cereus 9632 and Pseudomonas aeruginosa WT. Bacterial culture is applied in synthetic electroplating wastewater. Some Cd concentrations are used to perform Range Finding Test by bacterial culture. The study was conducted in a batch system for three days. The viability test was done by measuring the value of Optical Density and Total Plate Count, while bacterial DNA profile was analyzed by using electrophoresis. The cell viability of B.cereus ATCC 9632 and P.aeruginosa WT had the same pattern which is the higher concentration of Cd metals on cell bacteria surface, the lower cell bacteria viability. The DNA of the control bacteria has the difference between the size and number of bands.

Artisanal and small-scale gold is known to be sources of mercury pollution. This mercury contamination occurs when gold is isolated by the amalgamation method, contamination occurs. Mercury pollution in small-scale artisanal gold mining in the Kulon Progo area of Yogyakarta, the lowest tailing content was 164.49 mg kg-1, and the highest was 383.21 mg kg-1. This value exceeded the quality standard stipulated by Indonesian Government Regulation 22 of 2021 of 75 mg kg-1. The technology that can control pollution is stabilization/solidification (S/S). This research aimed to determine the optimum composition of the tailings mixture with tras soil. Variations in the design of tras soil with tailings were 100:0, 90:10, 80:20, 70:30, 60:40, 50:50, 40:60, 30:70, 20:80, and 10:90. The results showed that the optimum tras: tailings soil composition was 90:10, with a compressive test of 31 t m-2. Toxicity Characteristic Leaching Procedure (TCLP) was 0.0033 mg L-1 according to the quality standard of Indonesian Government Regulation no. 22, 2021, with a value of 0.05 mg L-1. The compressive strength results follow the quality of the US EPA of 35 t m-2.
