“…The morphology of the root system may also justify differences in AMF communities among plants [40]. In the case of Canna spp., they have a variable root length (18-20 cm) consisting of a large root area and biomass [41], unlike Watsonia spp. that are characterized by having basal-rooting corms with associated dormancy, where corm tunics consist of the thickened fibrous remains of cataphylls and lower leaf bases [41,42].…”

However, for the latter plants, very little information is available concerning radicular system development and association with wetland cosmos.…”

Constructed wetlands (CWs) are biological wastewater treatment systems that comprise several components where plants and associated organisms play an important role in water depuration. Microbial studies emphasize bacterial dynamics, whereas studies of arbuscular mycorrhizal fungi (AMF) are scarce and the functional role of AMF in aquatic and wetland plants is poorly understood. The aim of this study was to analyze the AMF communities colonizing the roots of Canna indica, Canna flaccida, and Watsonia borbonica inhabiting a CW treating wastewater of a tourism unit. The dynamics of the AMF communities were evaluated by Denaturing Gradient Gel Electrophoresis (DGGE) of 18S rRNA gene amplification products along cold (C) and hot (H) seasons for three consecutive years. DGGE profiles allowed the estimation of AMF species richness (S), and Shannon-Wienner (H) and Pielou (J) indexes, for the different plant species, showing differences between species and along the years. Excised bands from DGGE were analyzed and identified through sequencing for arbuscular mycorrhiza, revealing the presence of AMF strains closely related to Glomus sp., Rhizophagus sp. and Acaulospora sp. genera. Concomitant water quality analyses showed that the system was effective in organic and nutrient removal during the sampling period. Findings from this study suggest that AMF diversity found in the CW is influenced by the water constituents, season, and plant species.

“…Air limbah grey water salah satunya berasal dari sisa air mandi dan cuci yang biasanya dibuang ke saluran drainase [1]. Berdasarkan penelitian yang dilakukan [2], sebanyak 33,3% limbah cair domestik umumnya berasal dari toilet, 33,3% dari aktivitas mandi, dan sisanya berasal dari aktivitas mencuci pakaian dan aktivitas di dapur. Air limbah domestik yang berasal dari 60-80% air bersih dapat menjadi polutan terbesar yang masuk ke perairan dan dibuang ke lingkungan dalam bentuk limbah [3].…”

Evaluasi Kinerja IPAL Individual SANFAB ST 600 dengan Penambahan Anaerobic Granule Bacteria terhadap Outlet IPAL Domestik di Dusun Karangmojo, Boyolali

ABSTRAK. Kabupaten Boyolali memiliki jumlah penduduk tertinggi kedua di eks-Karesidenan Surakarta sehingga limbah cair domestik yang dihasilkan juga tinggi. Hal ini mendorong upaya pengelolaan limbah domestik menggunakan SANFAB ST 600. Penelitian ini bertujuan untuk mengetahui efektivitas kinerja IPAL Individual SANFAB ST 600 setelah diberi perlakuan dengan Anaerobic Granule Bacteria. SANFAB ST 600 memiliki volume 600 L dan berkapasitas 1-4 orang. Air limbah rumah tangga yang dialirkan ke inlet ST akan menuju ke settler, selanjutnya mengalir secara upstream dalam unit Anaerobic Filter dan terjadi penguraian zat pencemar oleh bakteri anaerobik. Pengambilan sampel dilakukan pada dua rumah di Dusun Karangmojo, Kabupaten Boyolali. Sampel diuji di BLKK Yogyakarta untuk parameter TSS, COD, BOD, konsentrasi Amonia, pH, dan ORP. Pada minggu ketiga di Rumah Bapak Wahyudi, karakteristik outlet ST memiliki nilai TSS 25,5 mg/L, Amonia 0,255 mg/L, BOD 25,01 mg/L, dan COD 47,92 mg/L sehingga sudah sesuai baku mutu. Dari hasil uji dilakukan perhitungan efektivitas pengolahan TSS, BOD, dan COD dengan cara menghitung selisih konstanta inlet dan outlet dibagi dengan konstanta inlet serta perhitungan rasio BOD/COD dengan membagi kadar COD dan BOD setiap sampel. Dari sumber limbah WC dan kamar mandi (Rumah Bapak Wahyudi) bakteri bekerja lebih efektif dibanding sumber limbah WC (Rumah Bapak Somowirejo) dengan efisiensi lebih dari 80% pada minggu ketiga penambahan bakteri. Kata kunci:anaerobic granule bacteria, efisiensi, limbah domestik, IPAL ST 600 ABSTRACT. Boyolali Regency has the second highest population in the residence of Surakarta so the domestic wastewater generation is also high. This led to the management of domestic wastewater using Individual WWTP SANFAB ST 600. This study aims to determine the effectiveness of Individual WWTP SANFAB ST 600 after being treated with Anaerobic Granule Bacteria. The SANFAB ST 600 has a volume of 600 L and a capacity of 1-4 people. Domestic wastewater that flows into the ST inlet will go to the settler, then flows upstream into the Anaerobic Filter unit and decomposed by anaerobic bacteria. Sampling was carried out at two houses in Karangmojo, Boyolali Regency. Samples were tested at BLKK Yogyakarta for parameters of TSS, COD, BOD, Ammonia concentration, pH, and ORP. In the third week at Wahyudi's house, the characteristics of the ST outlet had a value of TSS 25.5 mg/L, Ammonia 0.255 mg/L, BOD 25.01 mg/L, and COD 47.92 mg/L so it already suitable with the standard. From the test results, the effectiveness of TSS, BOD, and COD reduction is calculated by the difference between the inlet and outlet constants divided by the inlet constant and also calculating the BOD/COD ratio by dividing the COD and BOD levels of each sample. From the source of WC and bathroom waste (Mr. Wahyudi's House) the bacteria worked more effectively than the WC source (Mr. Somowirejo's House) with an efficiency of more than 80% in the third week after bacteria addition.Keywords:anaerobic granule bacteria, efficiency, domestic wastewater, IPAL ST 600

“…The main air pollutants are smoke and dust, particulate matter (PM2.5), sulphur dioxide (SO2), and nitrogen dioxide (NO2) [34,35]. Water pollution includes chemical oxygen demand (COD), ammonia nitrogen, nitrogen, phosphorus, petroleum, volatile phenol, plumbum, mercury, hexavalent chromium, chromium, and arsenic [36]. There are different types of solid wastes, such as metallurgical solid waste residue [37].…”

With the rapid development of urbanization and industrialization in China, environmental issues have become an urgent problem, especially issues related to air, water, and solid-waste pollution. These pollutants pose threats to the health of the population and to that of communities and have a vicious influence on the healthcare system. Additionally, pollution also exhibits spill-over effects, which means that pollution in the local region could affect the healthcare services in a neighboring region. Therefore, it is necessary to explore the relationship between pollution and healthcare. A spatial autocorrelation analysis was conducted and spatial panel econometric models were constructed to explore the characteristics of pollution and healthcare services in China and the relationship between them using data on all 31 provinces over 12 consecutive years (2006–2017). The results showed that the utilization of healthcare services and environmental pollution were not randomly distributed; unsurprisingly, air pollution and solid-waste pollution were mainly found in parts of northern China, while water pollution was highest in southern and coastal China. In addition, environmental pollution exhibited spill-over effects on healthcare services. For example, a 1% increase in solid waste in one specific geographical unit was estimated to increase the inpatient visits per capita in adjacent counties by 0.559%. Specifically, pollution showed different degrees of influence on healthcare services, which means that the impact of environmental pollution on the number of outpatient visits is greater than on the number of inpatient visits. Our results provide the government with evidence for effectively formulating and promulgating policies, especially policies aimed at tackling spill-over effects among different regions.
