"Kota Metro merupakan salah satu kota dengan tingkat pelayanan air perpipaan yang rendah (5,05%), sehingga sebagian besar masyrakatnya menggunakan air tanah dengan sistem self-supply. Akan tetapi, keamanan sistem sumber self supply saat ini menjadi isu di masyarakat. Metode continuous monitoring dari April – Oktober 2021 melalui telepon setiap bulan dilakukan untuk membantu penilaian tingkat layanan air minum. Tujuan dari penelitian ini adalah menganalisis variabilitas sumber air bersih dan air minum, menganalisis variabilitas tingkat pelayanan air minum yang dipersepsikan aman, menganalisis variabilitas biaya operasional dan pengelolaan layanan sumber air minum di rumah tangga, dan menganalisis intervensi pengolahan air minum di rumah tangga untuk meningkatkan kualitas air minum. Analisis dilakukan dengan analisis statistik deskriptif dan software SPSS 24 untuk uji Regresi Logistik Biner. Hasil menunjukkan 97% sumber air masyarakat Kota Metro adalah sumber air self-supply, yang didominasi oleh sumur gali tak terlindungi milik pribadi (45% sumber air bersih dan 30% sumber air minum). Berdasarkan persepsi rumah tangga (keamanan, rasa, penampilan, bau, keandalan, dan ketersediaan air minum), air isi ulang dan air kemasan memiliki tingkat keamanan paling konsisten selama 6 bulan survei (100%). Sistem non-self-supply diketahui lebih aman dari sistem self-supply dengan persentase 98% dan 95%. Variabel kejadian banjir diketahui signifikan terhadap penilaian tingkat pelayanan sumber air minum yang dipersepsikan aman dengan peluang 0,059 kali dalam mempengaruhinya. Rata-rata biaya yang dibutuhkan untuk maintenance mesin pompa adalah Rp 683.750,00 dan untuk maintenance lainnya (pipa, kran air, dll) sekitar Rp 85.833,00 per rumah tangga. Sedangkan biaya yang dihabiskan oleh 1 rumah tangga dalam 1 minggu untuk air isi ulang adalah sekitar Rp 19.751,00, sedangkan untuk air kemasan sekitar Rp 40.986,00. Variabel yang mempengaruhi biaya air minum adalah pengolahan air dengan perebusan yang berpeluang 0,029 kali. Berdasarkan persepsi rumah tangga, masalah sumber air minum yang paling banyak terjadi pada sumber air baku adalah penampilan (29,4%) dan bau (28,3%), serta kadar E.coli (72%) pada air minum. Dengan demikian, dibutuhkan intervensi strategi pengolahan air minum untuk mengatasi permasalahan yang ada dan meningkatkan kualitas air minum. Adapun intervensi pengolahan air minum yang direkomendasikan untuk menyelesaikan masalah tersebut adalah Slow Sand Filter (SSF) dengan media tambahan berupa Granular Activated Carbon (GAC) serta unit disinfeksi sinar UV.

Metro City is one of the cities with a low level of piped water service (5,05%), so that most of the people use groundwater with a self-supply system. However, the safety of the self-supply source system is currently an issue in society. A continuous monitoring method from April – October 2021 by telephone every month was carried out to help assess the level of drinking water services. The purpose of this study are to analyze the variability of clean water and drinking water sources, to analyze the variability of the level of drinking water services that are perceived as safe, to analyze the variability of operational and maintenances costs of drinking water facility in households, and to analyze the intervention of drinking water treatment in households to improve the quality of drinking water. The analysis was carried out using descriptive statistical analysis and SPSS 24 software for the Binary Logistics Regression test. The results show that 97% of Metro City's water sources are self-supply water sources, which are dominated by private unprotected dug wells (45% for clean water sources and 30% for drinking water sources). Based on household perceptions (safety, taste, appearance, smell, reliability, and availability of drinking water), refill and bottled water had the most consistent level of safety during the 6 months of the survey (100%). Non-self-supply systems are known to be safer than self-supply systems with a percentage of 98% and 95%, respectively. The flood incident variable is known to be significant to the assessment of the service level of drinking water sources that are perceived as safe with a 0,059 times chance of influencing it. The average cost required for pump engine maintenance is Rp 683.750,00 and for other maintenance (pipes, water faucets, etc.) it is around Rp 85.833,00 per household. Meanwhile, the cost spent by 1 household in 1 week for refill water is around Rp 19.751,00, while for bottled water it is around Rp 40.986,00. The variable that affects the cost of drinking water is water treatment by boiling which has a chance of 0.029 times. Based on household perceptions, the most common drinking water source problems that occur in raw water sources are appearance (29,4%) and smell (28,3%) and E.coli (72%) in drinking water. Thus, intervention strategies for drinking water treatment are needed to overcome existing problems and improve drinking water quality. The recommended drinking water treatment intervention to solve this problem is the Slow Sand Filter (SSF) with additional media in the form of Granular Activated Carbon (GAC) and UV disinfection unit."

"Keberadaan Antimicrobial Resistance (AMR) di lingkungan mengalami peningkatan seiring berjalannya waktu. AMR mulai ditemukan terkandung pada air tanah sebagai salah satu pencemar mikrobiologis. Kota Metro sebagai mayoritas pengguna air tanah dari sumur bor dan gali, yakni mencapai 90% perlu waspada terhadap keberadaan AMR. Penelitian ini bertujuan untuk menganalisis konsentrasi E. coli dan E. coli resistan terhadap cefotaxime serta rasio perbandingannya, menganalisis pengaruh faktor curah hujan, suhu, kelembaban, pH, total padatan terlarut, dan kekeruhan terhadap kadar konsentrasi, serta memberikan rekomendasi tindakan pengelolaan air tanah berdasarkan prevalensi bakteri E. coli dan E. coli resistan di Kota Metro. Penelitian ini dilakukan di 11 lokasi selama bulan November – Februari menggunakan IDEXX Colilert-18 dan Quanti-Tray/2000 untuk mendeteksi konsentrasi E. coli dan E. coli resistan melalui penggunaan antibiotik cefotaxime. Hasil penelitian menunjukkan sebanyak 67% air tanah mengandung E. coli dan sebanyak 27% di antaranya bersifat resistan terhadap cefotaxime. Persentase keberadaan (1) E. coli dan (2) E. coli resistan dengan kategori risiko sangat tinggi (>100 MPN/100 ml) mencapai (1) 24% dan (2) 0%; risiko tinggi (>10 – 100 MPN/100 ml) (1) 13% dan (2) 2%; risiko menengah (1 – 10 MPN/100 ml) (1) 31% dan (2) 16%; dan risiko rendah (<1 MPN/100 ml) (1) 33% dan (2) 82%. Peningkatan konsentrasi E. coli berkorelasi dengan faktor curah hujan, suhu, dan kekeruhan sedangkan peningkatan konsentrasi E. coli resistan berkorelasi dengan faktor curah hujan. Hubungan korelasi didapatkan melalui uji peringkat Spearman berdasarkan signifikansi (p-value) < 0,05. Berdasarkan hasil prevalensi, masyarakat dapat meminimalisasi konsentrasi dengan cara memodifikasi kondisi fisik sumur agar sesuai dengan standar yang telah ditetapkan oleh Kementerian PUPR dan SNI. Masyarakat juga dapat menggunakan filter sederhana, misalnya filter granular untuk memfiltrasi air sebelum digunakan. Walaupun langkah tersebut dilakukan, perlu diingat bahwa terdapat faktor pengaruh lain yang dapat memengaruhi konsentrasi E. coli dan E. coli resistan, salah satunya adalah kontaminan di sekitar sumur, seperti feses manusia, feses hewan ternak, dan sisa air buangan rumah tangga. Maka, peran pemerintah dalam penyediaan layanan fasilitas air bersih menjadi salah satu langkah untuk mengurangi penggunaan air tanah yang terkontaminasi.

The prevalence of Antimicrobial Resistance (AMR) in the environment has been increasing over time. AMR has been detected in groundwater as one of the microbiological pollutants. Metro City, where the majority relies on groundwater from boreholes and wells, accounting for 90%, must be vigilant against AMR. This study aims to analyze the concentration of E. coli and cefotaxime-resistant E. coli, along with their ratio, to analyze the influence of rainfall, temperature, humidity, pH, total dissolved solids, and turbidity on concentration levels, and to provide recommendations for groundwater management based on the prevalence of E. coli and cefotaxime-resistant E. coli in Metro City. The research was conducted at 11 locations from November to February using the IDEXX Colilert-18 and Quanti-Tray/2000 to detect the concentration of E. coli and cefotaxime-resistant E. coli through the use of antibiotics. The results showed that 67% of the groundwater contained E. coli, with 27% being resistant to cefotaxime. The percentage of presence of (1) E. coli and (2) cefotaxime-resistant E. coli with very high-risk categories (>100 MPN/100 ml) reached (1) 24% and (2) 0%; high risk (>10 – 100 MPN/100 ml) (1) 13% and (2) 2%; moderate risk (1 – 10 MPN/100 ml) (1) 31% and (2) 16%; and low risk (<1 MPN/100 ml) (1) 33% and (2) 82%. The increase in E. coli concentration correlated with rainfall, temperature, and turbidity, while the increase in cefotaxime-resistant E. coli concentration correlated with rainfall. Correlation relationships were determined through Spearman rank tests based on significance (p- value) < 0.05. Based on the prevalence, the community can minimize concentrations by modifying the physical conditions of wells to meet the standards set by the Ministry of Public Works and SNI. The community can also use simple filters, such as granular filters, to filter water before use. Despite these measures, it should be noted that there are other influencing factors that can affect the concentration of E. coli and cefotaxime-resistant E. coli, such as contaminants around the well, such as human feces, livestock feces and household wastewater. Therefore, the government's role in providing clean water facilities becomes one of the steps to reduce the use of contaminated groundwater."

"Pelayanan air perpipaan di Indonesia yang masih kurang mendorong masyarakat untuk menggunakan sumber air nonperpipaan seperti air tanah dan air isi ulang. Namun berdasarkan beberapa penelitian, air nonperpipaan diketahui memiliki risiko akibat kontaminasi bakteri dan patogen. Studi ini dilakukan sebagai upaya peningkatan kualitas air minum dengan mengetahui persebaran kontaminasi E. coli, faktor yang mempengaruhinya, serta membandingkan risiko kesehatan air minum nonperpipaan di Kota Bekasi dan Metro. Penelitian dilakukan dengan metode Most Probable Number (MPN) untuk mengetahui konsentrasi bakteri dan metode Quantitative Microbial Risk Assessment (QMRA) dengan indikator bakteri E. coli dan patogen indeks Salmonella. Pengujian kualitas air minum menunjukkan bahwa terjadi kontaminasi E. coli sekitar 26,7% dari total 202 sampel di Kota Bekasi dengan rata-rata 18,7 MPN/100 mL. Sedangkan di Kota Metro 30,0% dari 190 sampel terkontaminasi E. coli dengan rata-rata 77,3 MPN/100 mL. Berdasarkan uji korelasi Spearman¸ faktor seperti sumber air, pewadahan, dan pengolahan air tidak menunjukkan adanya korelasi terhadap konsentrasi E. coli, kecuali untuk faktor pewadahan di Kota Metro yang berhubungan signifikan dengan E. coli ≥100 MPN/100 mL. Kemudian hasil penelitian mengenai rasio patogen indeks Salmonella dengan sampel air tanah di kota Bekasi (n=7) diperoleh nilai rasio sebesar 0,03. Hasil perhitungan analisis QMRA dengan simulasi Monte-Carlo di Kota Bekasi menunjukkan bahwa air tanah memiliki nilai median beban penyakit sebesar 0,01 ± 0,03 DALY/orang/tahun dan air isi ulang dengan nilai sebesar 0,003 ± 0,02 DALY/orang/tahun. Sedangkan, untuk Kota Metro diperoleh sebesar 0,04 ± 0,04 DALY/orang/tahun untuk air tanah dan air isi ulang sebesar 0,03 ± 0,04 DALY/orang/tahun. Seluruh nilai yang diperoleh melebihi batas nilai maksimum menurut WHO yaitu sebesar 10-4 DALY/orang/tahun. Oleh karena itu, intervensi yang tepat perlu dilakukan oleh pemerintah untuk mengedukasi masyarakat tentang konsumsi air minum yang aman dan layak

Piped water services in Indonesia are still relatively low. This condition encourages people to use non-piped water sources such as groundwater and refilled water. However, based on several studies, non-piped water is known to have risks due to bacterial and pathogen contamination. This study was conducted as an effort to improve drinking water quality by knowing the distribution of E. coli contamination, the factors that influence it, and comparing the health risks of non-piped drinking water in Bekasi City and Metro. The research was conducted using the Most Probable Number (MPN) method to determine the concentration of bacteria and the Quantitative Microbial Risk Assessment (QMRA) method with E. coli as indicators and Salmonella as reference pathogen. The drinking water quality testing showed that there was around 26.73% E. coli contamination from a total of 202 drinking water samples in Bekasi City with an average of 18.74 MPN/100 mL. Whereas in Metro City 30% of 190 samples were contaminated with E. coli with an average of 77.31 MPN/100 mL. Based on the Spearman correlation test¸ risk factors such as water sources, containers, and water treatment did not show a correlation with E. coli concentrations, except for the container factor in Metro City which is significantly related to E. coli ≥100 MPN/100 mL. Then to find out the reference pathogen ratio, a Salmonella concentration test was carried out for groundwater in the city of Bekasi (n=7) and a ratio value of 0.03 was obtained. The results of QMRA analysis calculations using Monte-Carlo simulations in Bekasi City show that groundwater has a median disease burden value of 0.01 ± 0.03 DALY/person/year and refill water with a value of 0.003 ± 0.02 DALY/person/year year. Whereas for Metro City, the median disease burden of groundwater was 0.04 ± 0.04 DALY/person/year and for refill water it was 0.03 ± 0.04 DALY/person/year. All values ​​obtained exceeded the maximum value limit according to WHO, namely 10-4 DALY/person/year, therefore proper intervention from the government is needed to educate the public about consumption of safe drinking water."

"A big potential of Bank Syariah market (Research in Potential and Community preference toward Bank Syari'ah in 2006) and basic concept of Bank Syari'ah have fulfilled the needs of community, so, Indonesian Bank in 2002 issued the regulations of Indonesia Bank No. 4/1/PBI/2002 dated march, 21st, 2002 about the extension of Bank activities in conventional become public Bank which is based on syari'ah principles, and opening Bank office is based on Public Conventional Bank.Bank Syari'ah could be developed in the future if it will not only promote moral values and focus on the aspect of religious emotion, but it should be focused on the reality of economy to complete conventional Bank and it is supported by correctly comprehension from social either deal with principles, product or any kinds of services which are offered and other things that reflect to Bank Syariah. Therefore, any good products, and good services offered will not touch community if their comprehension is still ambiguity about Banks Syari'ah.The correct comprehension of Bank Syariah is not only coming from Moslem, but also from non Moslem, mainly non Moslem who come from low economy will become a potential market for customer of Bank Syari'ah, one of customers is from Tionghoa community. The comprehension of Bank Syari?ah by Tionghoa community will be shown from their perception and attitude to the Bank Syariah itself.The perception of customers to the product will be influenced by their attitude and automatically to their action. Perception has an impact to marketer strategies, because the customers will decide which product should be felt by them than reality objectively. Meanwhile, attitude is one of crucial concepts, which is used by marketer to understand the customers by comprehending customers' attitude. Marketer can decide the properly action which is related to their product. Besides, customers' attitude is essential factor and it will impact to customer decision to buy or not the product and services offered. There are three market segments; they are conventional, floating mass and Shariah loyalist. The customers of Bank Syariah is categorized into three groups namely; groups which dealt with emotional and loyalist, rational customer, and the unity between rational and emotion.Perception is the process through which individuals are exposed to information, attend to that information, and comprehend. Perception they are exposure model, attention model and coprehension model.The sample in this research used 100 people. And data analysis method is proposed to recognize Tionghoa's community perceptions against syariah banking which is conducted by using descriptive analysis. To analyzed Tionghoa community attitude towards syariah banking by using Fisbein Multi Attribute Model.Based on the result of research analyses which have been conducted, it is shown, the majority of Tionghoa community who lived in Pekanbaru city assume that Bank Syariah is not the same as conventional Bank. Sharing profit as the bank applied is not equal to interest system in conventional bank. Tionghoa's community has a positive attitude to Bank Syariah, which has that community is taking well of syariah banking principle and product. The factor that most influence Tionghoa community in choosing Bank is safety from the Bank itself.Based on the research analyses in this study, it could be suggested to Bank Syariah as in the following:- It takes much more vigorous efforts for syariah bank and on its way own to distribute and introducing syariah banking to Tionghoa society in Pakanbaru city, through even promotion, advertising or other marketing activity. Such as, disposing an image that syariah bank is only performing their services for most moslem or any islamic terms applications that equipped and enriched with a most common and popular in society ect.- A systematic and strategic paces of syariah banking part, would be needed so that Tionghoa society could be directed and so forth, embraced them to be their partner or business counterpart to syariah bank. For instance, firstly, through rewarding to non-moslem customer or even their own business counterpart. Secondly, to bring forward profesionalism aspect of syariah bank dan their customer services.- Everything that emerge convenience and secure of possibility of lost either as customer or business counterpart should be done directly or non directly thorugh financial independent or third party of management."

"Indonesia rentan terhadap perubahan iklim dan kualitas air tanah. Di Kota Metro, air tanah sebagai sumber air utama rentan tercemar oleh bakteri E. coli dari fasilitas sanitasi seperti cubluk dan tangki septik, terutama saat hujan.

Indonesia is vulnerable to climate change and groundwater quality issues. In Metro City, groundwater, the primary water source, is prone to contamination by E. coli bacteria from sanitation facilities such as pit latrines and septic tanks, especially during rain. This study was conducted to analyze the influence of rain intensity, horizontal distance, and groundwater table on E. coli contamination in groundwater around sanitation facilities in Yosodadi Village, Metro City. Seventeen monitoring wells or piezometers were installed at horizontal distances of 2 meters and 5 meters from septic tanks in three households. A total of 130 E. coli tests were conducted in January-February 2024 using IDEXX Colilert-18. Based on the analysis conducted on three households, the groundwater contamination risk around sanitation facilities 24 hours after rain was 46% in the very high category, 17% in the high category, 18% in the medium category, and 18% in the low category. Statistical tests indicated that rain intensity, distance, and groundwater table have a significant relationship with E. coli contamination around septic tanks, with a p- value <0.05. E. coli contamination exceeding 1000 MPN/100 mL in groundwater around sanitation facilities is 3.74 times more likely to occur after heavy rain (>20 mm/hour) compared to light rain (<20 mm/hour). E. coli concentrations at a 2-meter distance between the piezometer and septic tank were higher than at a 5-meter distance. The groundwater table height correlates with E. coli contamination in groundwater, with higher concentrations when the groundwater table is high. The findings of this study suggest that rainfall can increase E. coli contamination in groundwater, so cooperation between the government and the Metro City community is needed to improve septic tank construction, implement household- scale groundwater treatment programs, promote safe sanitation practices, and switch from groundwater to PDAM water services."
