Abstract

Densely urbanized area required solution to control rainwater run-off in the form of water recharge techniques which was efficient and effective. One of the most conducive water recharge techniques in densely urbanized was recharge well. In general the well design could be compared to pursuant to its wall construction, which might vary in porosity. Based on determination of those methods of recharge well dimension, it was found that Sunjoto method use dynamic approach and yields well dimension which was relatively small. There were three types of suggested recharge wells. The selection of the recharge well types was in accordance to the condition of local area. Each typical well had advantages and disadvantages. At limited backyard area, it was suggested to apply recharge well design (Type II), which some part of the well wall was impervious and the other part was pervious. In road area, it was suggested to use recharge well (Type I), with permeable bottom and all wall was made from brick. In the relatively wide backyard, it was suggested to use recharge well (Type III), where the entire wall was porous.

Abstract

Bentuk sistem penyaluran lindi pada sanitary landfill pada umumnya digunakan sistem sisir. Posisi pipa primer pada sistem ini berada di sepanjang tepi sel. Bentuk sistem penyaluran lindi lainnya adalah sistem tulang ikan, yaitu pipa primer berada di tengah sel. Kedua bentuk tersebut akan dibandingkan keefektifannya dalam menyalurkan lindi. Digunakan variasi curah hujan untuk mengukur volume lindi persatuan waktu yang keluar pada outlet masing-masing sistem. Pada variasi penghujanan dengan PUH 10 tahun dan 25 tahun didapatkan selisih total volume kumulatif lindi yang keluar dari outlet sistem tulang ikan lebih banyak dibandingkan dengan sistem sisir, yaitu sebesar 1,98% dan 6,1%. Hasil penelitian menunjukkan sistem tulang ikan lebih efektif dalam menyalurkan lindi dibandingkan dengan sistem sisir. Berdasarkan analisa statistik “One way ANOVA”, variasi sistem penyaluran lindi dapat memberikan pengaruh yang signifikan, yaitu pengukuran volume lindi di outlet masing-masing sistem pada waktu pengamatan yang sama. Pada variasi penghujanan dengan PUH 10 tahun dan 25 tahun didapatkan P-Value sebesar 0 dan 0,027.

Abstract

The toxicity level of oil waste has not been identified as compared to the toxicity of lubricant oil. Therefore, the toxicity of oil waste was determined by using Gold fish (Cyprinus carpio) in a lab-scale ecotoxicity. The acute toxicity test was used as a method during the experiment which proceeded by the range finding tests to determine LC50 for 96 hours exposure. The concentration of 52,5 – 62,5% was applied for acute toxicity of oil waste and 61,0-68,5% was for lubricant oil. The result of experiment showed that LC50 for oil waste was (55,92 ± 1,04) mg/l and for lubricant oil was (64,80 ± 1,03) mg/l, hence it could be concluded that oil waste was more toxic than lubricant oil. Further, histopathology test showed that both samples, oil waste and lubricant oil, caused structural damage to the fish, which was shown by histopathological change of fish gills in the form of hyperplasia lamella.

Abstract

Masalah tinja menjadi persoalan tersendiri, terutama berkaitan dengan kandungan jasad hidup berbentuk bakteri, fungi dan jamur yang bersifat patogen dan penghasil racun. Dalam 125-300 g tinja manusia terkandung sekitar 300 milyar bakteri coli form. Kehadiran bakteri coli dalam bahan makanan dan minuman, sangat tidak diharapkan karena bisa menyebabkan penyakit. Di sisi lain, kandungan nutrien yang tinggi dalam tinja merupakan sumber pupuk organik yang paling lengkap dan baik untuk segala jenis tanaman. Dalam penelitian ini lumpur tinja distabilisasi dengan digester aerobik sistem kontinyu. Variasi yang dilakukan pada reaktor digester aerobik adalah solid retention time-SRT (umur lumpur) sebesar 10, 20, 30, 40, dan 50 hari. Parameter yang diteliti adalah TSS, VSS, kadar air, rasio C/N, bakteri coliform, pH, dan suhu. Hasil penelitian menunjukkan adanya pengaruh dari variasi SRT terhadap penyisihan parameter VSS. Reduksi kandungan organik (VSS) terbesar dicapai pada SRT 50 hari yakni 27,55%. Prosentase penyisihan terbesar untuk parameter bakteri coliform tercapai pada SRT 20 hari, yakni 99,79% namun masih belum bisa diaplikasikan ke tanah. Nilai C/N lumpur tinja pada SRT 50 hari adalah 6,12.

Abstract

Mangrove ecosystem is very sensitive to environmental changes. As feeding, nursery and spawning grounds and ultrafiltrator, mangrove ecosystem supports the fishery activities. Milkfish (Channos-channos) is a fish species, which is widely cultured in Indonesia. Three locations of milkfish aquaculture with different levels of mangrove density in Kejawan Putih was chosen for determining its influence to milkfish growth and productivity. The values of pH, dissolved oxygen, BOD, and total dissolved solids of the fishpond water and the water source were analysed twice per month for 3 consecutive months. Sizes of the harvested milkfish were measured according to its length, width, and weight. Results of this research showed that aquaculture with ± 10% of mangroves provided 80 % of milkfish life expectancy, with average length of 32 cm, and average weight of 300 gr. Aquaculture with no mangrove gave less than 60% milkfish life expectancy, with average length of 29,5 cm, and average weight of 150 gr.
