Abstract: Lacking in centralized wastewater treatment plant exist in all Indonesian cities. Drainage and river suffer from domestic wastewater contaminants. It also increases cost of water treatment plant operation if river used as water source. Using of greywater treatment system is believed as new solution. This paper will review application of greywater treatment in Indonesia. Some projects exist but most of them need supports from third party and their initial costs are high. Thus, low cost and reuse system in small community or household are important. Researches showed that constructed wetland is quite promising because the reduction of BOD concentration can reach 60-94%. However, land requirement and greywater generation could be the limitation and Anaerobic Baffled Reactor can be used as an alternative. Key words: domestic wastewater, greywater, reuse, decentralized wastewater treatment system, low cost treatment system, constructed wetlands

Kegagalan utama produksi udang dari budidaya tambak umumnya disebabkan oleh serangan penyakit dan kualitas air yang buruk akibat pencemaran. Suatu tindakan penyiapan lahan yang benar serta upaya menjaga mutu air pasokan akan sangat membantu dalam meningkatkan kembali produktivitas tambak. Suatu ujicoba aplikasi mikroba probiotik hasil isolasi dari wilayah pantura Jawa dikombinasi dengan sistem aerasi serta biofiltrasi dalan air tandon dilakukan pada tambak udang di Desa Limbangan, Kabupaten Pemalang, Jawa Tengah. Hasil yang didapat memperlihatkan terjadinya penurunan paramater-parameter kunci seperti Nitrat (NO3), Nitrit (NO2), Sulfat (SO4), Sulfida (H2S), Amonia (NH3) dan Phospat (PO4) secara signifikan. Selain itu pH dan DO air juga cenderung stabil.

Kehadiran telur cacing parasit di lingkungan menjadi perhatian sejak badan kesehatan dunia (WHO) mempublikasikan versi baru dari Pedoman untuk Penggunaan Kembali Air Limbah, Materi Fekal, dan Greywater untuk Pertanian dan Perairan tahun 2006 yang menjadikan telur cacing parasit sebagai polutan yang perlu mendapat perhatian. Batas ekuivalen telur cacing dalam lumpur adalah kurang dari 1 telur/gram total solid (TS). Telur cacing parasit, khususnya nematode Ascaris spp., menjadi ancaman dalam pemanfaatan air limbah dan lumpur sebagai produk sampingan Instalasi Pengolahan Air Limbah Domestik (IPALD) karena sifatnya yang resisten menyebabkan waktu ketahanan telur cacing lebih panjang dibandingkan mikroorganisme lain. Penelitian ini bertujuan untuk mengetahui jumlah telur cacing Ascaris spp. pada air limbah dan lumpur IPALD. Sampel air limbah dan lumpur diambil dari kolam anaerobic, fakultatif, dan maturasi IPAL Bojongsoang, Bandung. Metode deteksi dan kuantifikasi menggunakan prinsip pencucian, flotasi dan sedimentasi. Hasil penelitian ini adalah ditemukan telur cacing Ascaris spp. baik bentuk fertile maupun infertile di semua sampel dengan jumlah telur fertile lebih banyak dibandingkan bentuk infertile. Pada lumpur kolam anaerobic, fakultatif, dan maturasi jumlah telur Ascaris spp. fertile berturut-turut adalah 202, 40, dan 39 telur/gram sedangkan telur Ascaris spp. infertile adalah 82, 22, dan 27 telur/gram. Pada air inlet, kolam anaerobic, fakultatif, dan maturasi jumlah telur Ascaris spp. fertile berturut-turut adalah 3662, 1187, 613, dan 342 telur/liter sedangkan telur Ascaris spp. infertile adalah 1227, 333, 240, dan 280 telur/liter. Jumlah ini menunjukkan resiko tinggi pencemaran badan air dan daerah pertanian serta ancaman bagi kesehatan masyarakat di sekitar IPAL.

The high prevalence of helminth infection in Indonesia had encouraged the government to issue the Regulation of the Minister of Health concerning the Prevention of Soil-transmitted Helminths in 2017. Researches on the presence of helminth eggs in the environment, in soil and water as a media for transmitting the disease, are very few. Aim: The aim was conducted to investigate the potential presence of helminth eggs causing STH infections in two urban agricultural areas in northern and southern part of Bandung City. Methodology and results: Samples of water from the inlet and plantation area, as well as soil and water spinach produced by both regions, were collected and analyzed for the presence of helminth eggs using modified Bailinger methods. The number of helminth eggs of 1–119 eggs/L in water, soil, and vegetable samples. Conclusion, significance, and impact study: The results confirmed that the irrigation water used in both areas has been contaminated by feces. The average number of fecal coli exceeds the allowable value for the irrigation water source based on the Grade 4 of water quality criteria in Indonesia. Variations in the number of helminth eggs found in the samples can be caused by environmental conditions such as temperature, humidity, and soil types. The presence of helminth eggs in irrigation water and land samples exceeds the value recommended by WHO (2006) in the guidelines for the safe use of wastewater for agriculture. It can lead to an increased risk of helminth infection to consumers, agricultural workers, as well as residents around the farmland.

Introduction: Ascaris spp. eggs threaten sludge reuse because they are usually more environmentally resistant than other microorganisms. Consequently, the WHO recommended an acceptable limit of <1 helminth egg per gram of total solid as a health-based target for treated feces and fecal sludge and aimed to ascertain the effectiveness and reduction rate of Ascaris spp. eggs in sludge at various lime doses, ammonia concentrations, and temperature values. Methods: Eggs were detected and enumerated using the flotation and sedimentation principle. The reduction process was performed in batches with quick lime doses of 30% and 50% w/w, ammonia concentrations of 1,000 and 5,000 mg/L, and temperatures of 30°C and 50°C. Results and Discussion: The number of eggs of Ascaris spp. fertile in the ponds was 1.38 ± 1.38 eggs/gram to 42.98 ± 13.09 eggs/gram, and the infertile amount was 0.46 ± 0.80 eggs/gram to 17.82 ± 6.55 eggs/gram. Using a temperature of 40°C, 50% CaO, and 5,000 ppm ammonia resulted in the highest percentage of reduction, 97.98 - 98.09% but 1.12 eggs/gram was remaining. Conclusion: Higher pH and ammonia levels primarily affect egg decrease in Ascaris spp. To reduce 99% of Ascaris spp. eggs until it reaches <1 egg/g, a dose of 50% CaO is required, with 5,000 ppm ammonia at a temperature of 40°C for 2.7 hours.
