“…The IKA-INA method is a modified method of the NSF-WQI used by the US National Foundation (Ratnaningsih et al, 2020). The NSF-WQI is widely used as a reference in the procedure for compiling a water quality index in various countries, and has been widely used for assessing water quality in various countries, including Indonesia.…”

The Cikapundung River which crosses the city of Bandung is widely used for various purposes including as a drainage, tourist attraction and raw material for drinking water. In fact, the Cikapundung River is inseparable from environmental pollution, both from domestic waste around the river flow and industrial waste which ultimately has an impact on decreasing water quality. This research aims to to get an overview of the water quality condi-tions of the Cikapundung river which were assessed using Index IKA-INA method. To see how big the impact is on water quality in the Cikapundung River, a water quality index is used, which is a method for assessing the condition of a body of water based on selected parameters. Sampling was carried out at 3 sites during the dry and rainy seasons. Then the water quality criteria are determined using the National Sanitation's Foundation (NSF-WQI) method which has been modified to become the IKA-INA method and Pollution Index (IP) based on Minister of Environment Regulation No. 115 of 2003 concerning guidelines for determining water quality status. The results of the analysis using the IKA-INA method, the water quality of the Cikapundung River is generally in the "moderate" category, only one site is included in the "good enough" category, while the determination of water quality status using the Pollution Index method is included in the "fair" category. Moderately Polluted” for all sites both during the dry and rainy seasons with IP values ranging from 1.36 to 4.38.

“…Indeks Kualitas Air modifikasi Indonesia (IKA-INA) merupakan hasil pengembangan penyusunan indeks kualitas air berbasis pada formulasi NSF-WQI yang telah disesuaikan dengan kondisi di Indonesia melalui pengambilan keputusan secara metode Delphi (Ratnaningsih et al, 2019). Formulasi IKA-INA mempunyai dua komponen utama untuk dapat digunakan dalam penilaian kualitas air yaitu faktor pembobot parameter dan kurva subindeks (Ratnaningsih et al, 2020). Faktor bobot parameter adalah menetapkan urutan tingkat kepentingan masing masing parameter tersebut dalam kontribusinya terhadap kualitas air.…”

“…Data primer dalam penyusunan faktor pembobot untuk 10 parameter IKA-INA dikoreksi sehingga diperoleh bobot baru berdasarkan masing-masing parameter yang hilang. Nilai sub-indeks diperoleh dengan plotting atau memasukkan hasil analisis kualitas air masing-masing parameter IKA-INA ke dalam persamaan matematika untuk kurva sub-indeks IKA-INA (Ratnaningsih et al, 2020). Selain dilakukan koreksi terhadap faktor bobot dari data primer yang merupakan data awal, cara lain untuk penanganan data yang hilang adalah dengan melakukan pembagian hasil IKA yang diperoleh dengan total bobot parameter yang tersedia.…”

Kualitas air di suatu wilayah yang merupakan salah satu indikator lingkungan dapat dievaluasi menggunakan parameter fisika, kimia, dan biologi. Indeks Kualitas Air Indonesia (IKA-INA) dapat digunakan untuk menilai kondisi kualitas air secara menyeluruh pada lokasi dan waktu tertentu. IKA-INA dihitung dengan menggunakan sepuluh (10) parameter yaitu pH, Total Dissolved Solid (TDS), Total Suspended Solid (TSS), Dissolved Oxygen (DO), Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), NO3, NH3, Total Phosphate (TP) dan fecal coliform. IKA-INA tersebut merupakan indeks kualitas air yang dapat memberikan informasi secara sederhana. Dalam pemanfaatannya, tidak semua data parameter dalam IKA-INA tersebut dapat terpenuhi karena adanya data tidak valid atau data yang hilang. Kajian ini bertujuan untuk memberi alternatif rumusan IKA-INA dengan parameter yang tidak lengkap atau jika tidak semua data dalam parameters tersebut tersedia. Metode yang digunakan dalam menyusun rumusan adalah dengan melakukan koreksi faktor bobot parameter IKA-INA terhadap parameter yang hilang dan nilai Q (nilai sub-indeks). Setelah itu dilakukan uji coba pada nilai baku mutu air dalam Peraturan Pemerintah No. 22/2021 Lampiran VI serta pada data kualitas air sungai yang mewakili kualitas baik dan buruk. Hasil uji coba menunjukkan bahwa bobot parameter terkoreksi dapat digunakan untuk penanganan parameter yang hilang dalam penilaian kualitas air dengan metode IKA-INA. Hasil IKA-INA dengan parameter hilang yang menggunakan bobot terkoreksi dan hasil IKA-INA dengan parameter lengkap mayoritas memberikan status IKA yang tidak berbeda, kecuali untuk parameter fecal coli dan parameter yang mempunyai kadar jauh berbeda terhadap kondisi air secara keseluruhan.

Objective: This study aims to determine the characteristics of eco enzymes in the form of aroma, color, pH eco enzymes and identify the diversity of bacteria that play a role during the fermentation process. Method/design/approach: The research was carried out from August to December 2022, the first stage of making eco enzymes fermentation 3 months of organic waste three variants of Citrus sinensis Osb peel, Ananas comosus peel, and Citrullus lanatus peel, combined with 2 variants of vegetable residue of fern plants; Stenochlaena palutris and Diplazium esculentum. Eco enzyme yields were organoleptic tested and measured bacterial diversity with the Oxford Nanopore Technology (ONT) technique. Results and conclusion: Eco enzyme harvest organoleptic test results: pH 3.74, ethanol content 2.41%, color 1502 Pt.Co and the characteristic smell of fermentation. Bacterial diversity Test of bacterial diversity that plays a role during the eco enzyme fermentation process was carried out using the Oxford Nanopore Technology (ONT) technique, identified the diversity of lactic acid bacteria (BAL) at the taxon level, Phylum 7, Order 19, Familia 37, Genus 98 and species 269 lactic acid batteries (BAL). Eco enzyme 1 liter in 1000-1 liter of mineral groundwater fish pond can inhibit E-coli 36.1% of the original population. Research implications: This research contributes to the body of knowledge on eco enzymes, bacterial diversity in fermentation processes, and their potential applications in waste management and antibacterial activities. The implications of this study can pave the way for further research, innovations, and practical implementations in the field of eco-friendly technologies and sustainable waste management practices Originality/Value: The originality of this research lies in its focus on eco enzymes and bacterial diversity, while the value lies in its contribution to waste management practices, antibacterial applications, and advancements in environmentally friendly technology.
