Published: June 2020

© 2019 CSIRO. The number of New Zealand's freshwater fish listed as threatened has increased since 1992 when the first New Zealand threat classification system list was compiled. In this study, temporal and land cover-related trends were analysed for data on freshwater fish distribution, comprising more than 20 000 records for the 47 years from January 1970 to January 2017 from the New Zealand Freshwater Fish Database. The analysis included individual species abundance and distribution trends, as well as an index of fish community integrity, namely the Index of Biotic Integrity (IBI). Of the 25 fish species that met the requirements for analysis to determine changes in the proportion of sites they occupied over time, 76% had negative trends (indicating declining occurrence). Of the 20 native species analysed for the proportion of sites occupied over time, 75% had negative trends; 65% of these were significant declines and more species were in decline at pasture sites than natural cover sites. The average IBI score also declined over the time period and, when analysed separately, the major land cover types revealed that the IBI declined at pasture catchment sites but not at sites with natural vegetation catchments.

Published: June 2020

Background

The spread of antimicrobial resistance (AMR) is of worldwide concern. Public health policymakers and pharmaceutical companies pursuing antibiotic development require accurate predictions about the future spread of AMR.

Aim

We aimed to identify and model temporal and geographical patterns of AMR spread and to predict future trends based on a slow, intermediate or rapid rise in resistance.

Methods

We obtained data from five antibiotic resistance surveillance projects spanning the years 1997 to 2015. We aggregated the isolate-level or country-level data by country and year to produce country–bacterium–antibiotic class triads. We fitted both linear and sigmoid models to these triads and chose the one with the better fit. For triads that conformed to a sigmoid model, we classified AMR progression into one of three characterising paces: slow, intermediate or fast, based on the sigmoid slope. Within each pace category, average sigmoid models were calculated and validated.

Results

We constructed a database with 51,670 country–year–bacterium–antibiotic observations, grouped into 7,440 country–bacterium–antibiotic triads. A total of 1,037 triads (14%) met the inclusion criteria. Of these, 326 (31.4%) followed a sigmoid (logistic) pattern over time. Among 107 triads for which both sigmoid and linear models could be fit, the sigmoid model was a better fit in 84%. The sigmoid model deviated from observed data by a median of 6.5%; the degree of deviation was related to the pace of spread.

Conclusion

We present a novel method of describing and predicting the spread of antibiotic-resistant organisms.

Published: June 2020

An outbreak of coronavirus disease (COVID-19) occurred on the Diamond Princess cruise ship making an international journey, which led to quarantine of the ship at Yokohama Port, Japan. A suspected COVID-19 case was defined as a passenger or crew member who developed a fever or respiratory symptoms, and a confirmed COVID-19 case had laboratory-confirmation of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Between 3 and 9 February 2020, 490 individuals were tested for SARS-CoV-2 and 172 were positive (152 passengers (median age: 70 years; interquartile range (IQR): 64–75; males: 45%) and 20 crew (median age: 40 years; IQR: 35–48.5; males: 80%). Other than the Hong Kong-related index case, symptom onset for the earliest confirmed case was 22 January, 2 days after the cruise ship left port. Attack rates among passengers were similar across the decks, while beverage (3.3%, 2/61) and food service staff (5.7%, 14/245) were most affected. Attack rates tended to increase with age. A comprehensive outbreak response was implemented, including surveillance, provision of essential medical care, food and medicine delivery, isolation, infection prevention and control, sampling and disembarkation.

Published: June 2020

Soft corals (Alcyoniidae) can obtain the nutrients through the algae symbiont (zooxanthellae) and/or captures the prey with their tentacles. Increased mean sea surface temperatures cause damage to coral reef ecosystems, one of those mechanisms is reducing the feeding capacity in soft corals. Thus, this study aims to examine the feeding rates of soft corals Sinularia sp. and Sarcophyton sp. at different temperatures, to determine the effect of increasing temperature, feeding time and interaction between those factors on feeding rates of soft corals Sarcophyton sp. and Sinularia sp. samples of Soft corals were obtained from the cultured of PT. Dinar Darum Lestari in Sumberkima Bay Waters, Buleleng Regency. before the experiment, coral fragments were acclimatized for 2 weeks and fed twice a week at 26 ° C (control temperature). The Experiment started by increasing the water temperature in the aquarium 1°C every hour to reach 31°C (stress temperature). Once the temperature reached, it held for 5 days. Each aquarium (26 and 31°C) was fed by Artemia salina on the second and fourth days with density 100 animals/fragments in the morning for 3 hours. The remained prey was taken by Pasteur pipette and counted manually. The results showed that there was no significant difference of feeding rates in Sarcophyton sp. dan Sinularia sp. at both control and stress temperatures because both types of soft coral fragments have relatively the same temperature tolerance. The increased temperature significantly affected the feeding rate in both soft corals (P <0,000). However, feeding time and interaction between temperature and feeding time did not have a significant effect on the feeding rate. It is assumed that the increased temperature reduces the feeding rate in these soft corals. Moreover, these soft coral seems stress due to continuously incubate in high temperature (31°C) caused no significant difference in the feeding rates at all feeding times.  keywords: soft coral, Sarcophyton sp., Sinularia sp., increased temperature., feeding rate, feeding time

Published: June 2020

The findings from review of extant literature indicated that the actual impact of ERP is generally seen and felt by an organizations during its post implementation stage. It is in this stage that the organizations commence on their journey of using the ERP systems, and start relating to its utility for the activities and processes being carried out by the employees. It is therefore, essential for the organizations to effectively manage the performance of the ERP system in the post implementation stage to deliver expected benefits to the business. Accordingly, it is important to study and understand various influences prevailing upon the ERP system during the post implementations stage and use the knowledge to ensure better managing the deliverables of ERP systems, therein.  Evidence from the past studies suggest that the different business settings have varied notable influences on the ERP implementation across phases. The Higher Education Sector in India is growing at a pace, seen never before, and the need to respond to competition pressures, student acquisition, renewed needs of students, and other stake holders, regulatory impositions by the government, globalization. These are few of the many reasons prompting the Higher Education Institutions (HEIs) to consider and implement solutions to help them respond to these changing needs so as to better deliver stakeholder’s expectations and satisfaction. Productivity of users in the ERP post implementation stage plays an important role in ensuring performance and success of the ERP systems. Guided by the above observations, this paper, through an empirical study, investigates the influence of gender and the period of ERP operations post its implementation, on the productivity of users, across higher education institutions, in an Indian context.

METODA PENGHILANGAN ZAT BESI DAN MANGAN DI DALAM PENYEDIAAN AIR MINUM DOMESTIK
Authors: Said Nusa Idaman
Published: June 2020

Small amounts of iron and manganese are quite common in domestic water supply because of the presence of iron and manganese in the soil and rock formations through which the water passes in reaching the point of use. Iron and manganese is characterized by red-brown staining of bathroom fixtures and laundry, and cause taste and odor problems. Iron and manganese are brought into solution by biological reactions under anaerobic reducing conditions. When the water is exposed to air or oxygen, oxidation of iron and manganese occurs slowly, forming objectionable colloidal precipitates. The deposition of these precipitates will stain plumbing fixtures, interfere with laundering, and cause difficulties in water distribution systems by supporting growth of microorganisms such as clonotrix and crenotrix that can clog pipelines and cause taste and odor problems. Processes in which oxidation is followed by removal of suspended solids can effectively remove soluble iron and manganese from water. Three common processes for removing iron and manganese are: aeration-filtration, chlorination filtration, and potassium permanganate-manganese greensand filtration. This article describes these processes and present result from pilot’s studies of iron and manganese removal from water. Kata kunci : zat besi, mangan, aerasi, kkhlorinasi, filtrasi, mangan zeolit.

REMOVAL OF COMMERCIAL ANIONIC DETERGENT IN WATER USING CONTINUOUS PROCESS OF BIOLOGICAL REACTOR WITH ADDING OF PAC
Authors: Said Nusa Idaman
Published: June 2020

Synthetic detergents, mostly anionic detergents have been widely used in Indonesia  over past two decades, similar to its use in other developing countries, and residuals from such use have entered the country's riverine and estuarine systems. Detergent problems have become more serious especially in urban areas where the spread of sewerage systems are still low, even in drinking water treatment process. According to this reason, it is important to develop low-cost technology to solve this problem such as developing biological treatment for removing detergents.Effects OF continuous adding of powdeR activated carbon (PAC) on biological removal of anionic detergent in continuous reactor was assessed. Results of these experiments showed that introduction of PAC into biological treatment of anionic detergent (ABS or LAS), has indicated significant effect on removal efficiency. Conducting continuous feeding of PAC into bench scale of continuous process system for removal of detergent has resulted better stability of MBAS removal efficiency, even when MLSS concentration in aeration tank dropped or MBAS concentration in influent water rose rapidly. With continuous addition of PAC, the MBAS removal efficiency was relatively constant even when the water temperature dropped rapidly.  In other words, continuous feeding of PAC can improve the stability for shock loads or temperatures changes. At lower temperatures, micro organisms that were used for detergent removal in bench scale of continuous process system, need longer adaptation or acclimation periods compared with higher temperatures. Key Words: Commercial anionic detergent, biodegradation, biological reactor, powdered activated carbon (PAC).

The Jakarta groundwater is one of the water resources in which people rely on it in great deal. With the limitation of the Water Supply Company to serve its user, groundwater becomes very valuable and dependable resource. The magnitude of extraction reaches out above it’s save yield. In the year of 2002 about 1230 to 1590 millions cubic meters water were accumulated from precipitation. Approximately of 1027 million cubic meters each year about to be consumed by the people of Jakarta. The groundwater consumption tend to increase while the land capability to absorb groundwater decreasing as the land development expanding. Hidrologically the hydraulic conductivity of the Jakarta groundwater aquifer system is very low, so that the groundwater flowrate from the south region of Jakarta basin is also low. With the magnitude of extraction’s very havily, the cone of depression incident has been occurring in the north Jakarta region. Along with this incident, a land subsidence was also occurring in the neighboring area. To overcome these problems, the assessment of the artificial recharge to the Jakarta aquifer particularly at the critical locations has been done. Schemes of the artificial recharges were simulated. Locations and magnitudes of these schemes were recommended to prevent further depression and saltwater intrusions. Key words : groundwater, aquifer, basin Jakarta, simulation, artificial recharge.

Published: June 2020

The hydrological character of the rivers in Java has changed. The trend flow of upstream rivers in Java declined. Significance level of the trend decline in the upstream was large enough. This indicates that the basic flow (base flow) from these rivers has been reduced. The cause of the trend decline in river flow is strongly influenced by a combination of the effects of global climate change and the influence of anthropogenic. The influence of climate change is marked by decreasing annual rainfall. While anthropogenic influences include changes in land use, reduced water catchment area, increasing population pressures and settlements. To identify which factors are most influential between the two factors are very difficult to do because of limited data on land use change. Keywords: discharge, trend, climate change, landuse, anthropogenic

KEMAMPUAN ADSORPSI LOGAM BERAT Cu DENGAN MENGGUNAKAN ADSORBEN KULIT JAGUNG (Zea Mays)
Authors: Anggriawan Agus , Atwanda M. Yanggi , Lubis Nurhazizah , Fathoni Rif'an
Published: June 2020

Secara umum adsorpsi merupakan suatu proses pemisahan bahan dari campuran gas maupun cairan, bahan yang harus dipisahkan ditarik oleh permukaan adsorben padat lalu diikat oleh gaya-gaya yang berkerja pada permukaan tersebut. Karbon aktif merupakan salah satu adsorben yang paling sering digunakan untuk menjerap zat-zat tertentu pada suatu larutan seperti kandungan logam. Salah satu bahan alami yang dapat digunakan sebagai adsorben adalah kulit jagung. Kulit jagung memiliki kandungan selulosa yang cukup tinggi, sehingga dapat digunakan sebagai adsorben guna menyerap kandungan ion logam yang terkandung di dalam suatu larutan. Penelitian ini menggunakan NaOH dan H2O2 sebagai aktivator karbon kulit jagung terhadap adsorpsi kadar logam dalam larutan CuSO4. Dimana diketahui kadar awal kedua larutan CuSo4 sebesar 15 mg/L. Lalu dilakukan adsorpsi dengan adsorben karbon dari kulit jagung tanpa diaktivasi diperoleh penurunan, kadar CuSo4 sebesar 80%. Selanjutnya dilakukan adsorbsi dengan adsorben karbon aktif dari kulit jagung diperoleh hasil kadar CuSo4 sebesar 0,00 mg/L dengan penurunan sebesar 100%. Hal ini disebabkan karena didalam kulit jagung memiliki kandungan selulosa yang dapat dengan baik menyerap kandungan logam.Kata Kunci : Adsorpsi, Adsorben, Kulit Jagung, Aktivator

Smart Camera Traffic for Congestion using Fuzzy Methods Based on Serious Game
Authors: Kurniawan Fachrul , Sofiarani Ade
Published: June 2020

Penumpukan kendaraan bermotor sehingga menyebabkan kemacetan hampir terjadi di wilayah yang dinamakan kota. Penambahan kendaraan bermotor tidak sebanding dengan penambahan volume luas jalan yang dilalui. Kemacetan tidak hanya terjadi di jalanan tetapi juga terjadi pada titik-titik pertemuan jalan  (pertigaan ataupun perempatan). Permasalahan kemacetan di titik pertemuan kadangkala disebabkan waktu lampu lalulintas yang tidak bagus. Ketepatan dan optimalnya fungsi lampu lalulintas menjadi kunci akan terurainya kemacetan setiap kali ada pertemuan. Konektivitas lampu lalulintas dengan kamera CCTV yang didalamnya diberi metode fuzzy akan menjadi solusi dari permasalahan diatas. Dan hal ini bisa dibuktikan pada sebuah simulasi berbasis serious game. Smart camera dan lampu lalulintas menjadi solusi pada kota yang telah menerapkan sistem smart city. Hal ini terlihat jelas pada percobaan pada aplikasi berbasis serious game dimana hasilnya menunjukkan bisa menyelesaikan kemacetan yang terjadi pada simpul pertemua jalan yang terpasang lampu lalulintas.
