Over the last few decades more and more natural wastewater treatment systems have been built in Hungary. The present study is the first step in creating a broad database on the water quality parameters and on the pollutant removal efficiency of these systems. The investigation included 78 plants out of which we analysed 16 systems in detail. Four types of natural methods are evaluated: wetlands, ponds, bio-mechanical combined oxidation (BMKO) systems, and poplar plantations. Pond systems are efficient in ammonium-nitrogen (NH4-N) removal, reducing it with 83% (41-88%). Their chemical oxygen demand (CODCr) removal capacity is only 55% (37-81%). The only BMKO system that could be evaluated performs high CODCr (77%) and total suspended solid (TSS) (89%) removal. Removal of NH4-N and total nitrogen (TN) declines during the years of operation giving an average value of 39% and 49%, respectively. The system is not efficient in phosphorus removal (13%). In wetlands the 71% CODCr (53-96%), and 57% TSS (33-91%) removal provides satisfactory effluent quality most of the time. Wetlands performed low nutrient removal, i.e., 17% (-21-46%) for TN and 26% (-20-92%) for phosphorus. Poplar plantations are very effective in pollutant removal. Even the average removal of each nutrient type is above 75%. Several problems have occurred in the operation of natural treatment systems. However, if carefully planned and constructed, and the required maintenance work is done properly, they can be possible alternatives for wastewater treatment.

Berbagai jenis ikan, dengan bobot total lebih dari 650 kg ditemukan mati di pesisir Pantai Ancol tanggal 30 November 2015, diantaranya yang dominan adalah gulamah (Scianidae). Kematian ikan yang sering terjadi akan menyebabkan kerugian ekonomi yang signifikan. Identifikasi faktor penyebab terjadinya peristiwa ini sangat penting untuk diketahui dalam rangka pengelolaan populasi ikan dan penyusunan tindakan pencegahan sehingga bisa mengurangi frekuensi dan besarnya tingkat kematian ikan. Penelitian ini bertujuan untuk mengetahui sebaran spasial beberapa parameter kualitas airguna mengidentifikasi faktor penyebab kematian masal ikan di Teluk Jakarta yang terjadi pada tanggal 30 November 2015. Pengamatan dilakukan pada tanggal 1-3 Desember 2015 di 14 stasiun penelitian mencakup14 parameter fisika, kimia dan biologi perairan. Sebaran spasial beberapa parameter perairan dipetakan dengan menggunakan software ArcGIS 9.3. Parameter perairan (kedalaman, kecerahan, suhu air, pH, oksigen terlarut dan ORP (Oxidation Reduction Potential)) diukur secara insitu dan contoh air permukaan diambil untuk pengamatan plankton serta parameter kimia air di laboratorium (nitrat, fosfat, ammonia, biochemical oxygen demand, total suspended solid, sulfide dan bahan organik terlarut). Berdasarkan analisa dari 14 parameter fisika, kimia dan biologi perairan diketahui faktor penyebab kematian masal ikan di Teluk Jakarta pada 30 November 2015 disebabkan karena rendahnya kandungan oksigen terlarut(0,07mg/l pada lokasi pusat kematian ikan),kadar nutrien yang berlebihan(nitrat,0,003-0,389 mg/l dan fosfat 0,811-1,653 mg/l,)dan tingginya konsentrasi ammonia yang merupakan gas beracun dan berbau (0,227-1,944 mg/l). On November 30th, 2015, more than 650 kg fishes found dead in the coast of Ancol. The identification of its causes is very vital to develop mitigation for managing fish population and preventing economic loss. This study aims to examine several waters parameters to identify the factors causing mass deaths of fish. The study was conducted on 1-3 December 2015 in Jakarta Bay by analyzing 14 parameters of physical, chemical and biological aspect. Spatial distribution of water parameters mapped using ArcGIS 9.3 software. Some water parameters were measured in situ (depth, brightness, water temperature,pH, dissolved oxygen and ORP (oxidation reduction potential) while surface water samples were taken and analyzed in the laboratory (Nitrate, phosphate, ammonia, biochemical oxygen demand. The result showed that a mass fish kills in Jakarta Bay on 30 November 2015 due to low dissolved oxygen content, release of toxic gas into the water, excessive nutrient and high ammonia.

BACKGROUND: Domestic wastewater can cause health problems and pollute groundwater sources. Such pollution not only has a negative impact on health and the environment, but also on the cost in providing clean water. AIM: The outcome of domestic wastewater treatment through a proper technique is expected to meet the clean water quality standard for sanitation purposes. MATERIALS AND METHODS: The experiment was conducted to determine the effect of Hydraulic Retention Time (HRT) on the levels of Biochemical Oxygen Demand (BOD) and Total Suspended Solid (TSS) of domestic wastewater. The experiment was carried out with 6 variations of HRT, namely 1 hour, 2 hours, 4 hours, 6 hours and 8 hours with 4 repetitions. The media running process was carried out for 14 days until the reactor condition was in steady state. RESULTS: The results showed that the removal values ​​for COD, Oil and Fat, Ammonia and Total Coliform parameters were 68.03%, 46.51%, 69.64% and 68.99%, respectively. Based on the variation of HRT of 1 hour, 2 hours, 4 hours, 6 hours and 8 hours on the BOD parameter, the removal values ​​obtained were 11.7%, 21.3%, 34.7%, 49.0% and 64.1%, respectively. Furthermore, for the TSS parameter, the values obtained were 17.3%, 25.4%, 30.6%, 42.3% and 50.4%, respectively. CONCLUSION: HRT was proven to have a significant effect on the levels of BOD and TSS of domestic wastewater with a p-value of <0.05 at the 95% confidence level
