Phosphate Content in Cikaniki RiverThe Cikaniki River is one of the tributaries of Cisadane, which crosses the provinces of West Java and Banten. This river has a very high function and value for human life and water ecosystem. Phosphates formed naturally in formed of rock and undergo a weathering process, rocks gradually break down into phosphate ions dissolved in water. Phosphates in orthophosphates are produced by nature and are found in waste, whereas polyphosphates are often used in detergents, but in water the form of poly will turn into an ortho form. The analysis to find out the phosphate content in Cikaniki River. Phosphate analysis of river water refers to SNI 06-6989.31-2005, using the uv-vis spectrophotometric method in ascorbic acid. The results showed that the phosphate content in Cikaniki River still fulfilled the Standard Quality of PP no. 82 of 2001, is <0.2 mg / L except in Kampung Babakan Liud area. Phosphate contamination in river water can be derived from natural processes as well as from the addition of contamination due to human activities in the form of agriculture, industry, and household activities and the presence of excessive phosphate can lead to explosive growth of algae in the waters.Keywords: River, Phosphate, ascorbic acid, wasteABSTRAKSungai Cikaniki adalah salah satu anak sungai Cisadane, yang melintasi Provinsi Jawa Barat dan Banten. Sungai ini memiliki fungsi dan nilai yang sangat tinggi bagi kehidupan manusia dan ekosistem air. Fosfat terjadi secara alami dalam bentuk batuan dan mengalami proses pelapukan, batuan secara bertahap mengurai menjadi ion fosfat yang larut dalam air. Fosfat dalam bentuk ortofosfat diproduksi oleh alam dan ditemukan di limbah, sedangkan polifosfat sering digunakan dalam detergen, tetapi di dalam air bentuk poli akan berubah menjadi bentuk orto. analisis untuk mengetahui kandungan fosfat di Sungai Cikaniki. Analisis fosfat pada air sungai mengacu kepada SNI 06-6989.31-2005, menggunakan metode spektrofotometri uv-vis secara asam askorbat. Hasil penelitian menunjukkan kadar Fosfat di Sungai Cikaniki masih memenuhi Baku Mutu PP No. 82 Tahun 2001, yaitu  < 0,2 mg/L kecuali pada daerah  Kampung Babakan Liud. Pencemaran Fosfat di air sungai dapat berasal dari proses alamiah  maupun berasal dari penambahan cemaran akibat aktifitas manusia yang berupa pertanian, perindustrian, maupun kegiatan rumah tangga dan keberadaan fosfat yang berlebihan dapat menyebabkan terjadinya ledakan pertumbuhan alga di perairan.Kata Kunci: Sungai, Fosfat, asam askorbat, limbah

ABSTRAKSungai Kupang adalah salah satu sungai yang mengalir di Kota Pekalongan yang menerima limbah, baik dari industri, pertanian maupun domestik, Perkembangan industri dan pemukiman di sepanjang aliran sungai Kupang telah mempengaruhi kualitas air sungai. Penurunan kualitas air ditandai dengan perubahan warna air dan bau padahal sebahagian masyarakat di pinggiran sungai masih memanfaatkan air Sungai Kupang untuk kebutuhan sehari-hari. Penelitian ini bertujuan untuk menganalisis kualitas air sungai Kupang berdasarkan baku mutu kualitas air sungai menurut PP Nomor 82 Tahun 2001, menghitung beban pencemar Sungai Kupang dan menentukan Status Mutu Air serta merekomendasi upaya pengelolaan kualitas air Sungai Kupang Pekalongan. Pengukuran kualitas air dilakukan pada 6 titik pengambilan sampel. Parameter yang diukur dan diamati adalah parameter Temperatur, TSS, pH, DO, BOD, COD, Kromium dan Phosphat. Untuk analisis Status mutu air Sungai Kupang dengan menggunakan metode indeks pencemaran dan daya tampung beban pencemaran dengan menggunakan metode Qual2Kw. Hasil penelitian pada kualitas air Sungai Kupang menunjukkan parameter  COD di beberapa titik telah melebihi baku mutu. Sedangkan untuk parameter BOD di semua titik telah melebihi baku mutu yang dipersyaratkan. Nilai konsentrasi BOD terendah adalah sebesar 5,75 mg/l, sedangkan nilai BOD tertinggi sebesar 27 mg/l. Kandungan BOD meningkat diduga karena sepanjang aliran sungai yang di mulai dari hulu hingga hilir banyak menerima limbah buangan, sementara berdasarkan status mutu air menunjukkan penurunan kualitas air dari hulu sampai ke hilir sungai, dimana pada bagian hilir telah tercemar ringan. Dan untuk hasil perhitungan beban pencemaran Sungai Kupang dari hulu ke hilir mengalami peningkatan, untuk beban pencemaran konsentrasi TSS adalah sebesar 20.670,334 kg/hari, sedangkan konsentrasi COD adalah sebesar 16.517,777 kg/hari, dan konsentrasi BOD yaitu sebesar 6.618,643 kg/hari.Kata kunci: Water Quality, Pollution Load, Kupang River ABSTRACTSungai Kupang is one of the rivers that flow in Pekalongan city that receives the waste, both from industrial, agricultural and domestic, industrial and residential development along the river Kupang have affected the quality of river water. Water quality degradation characterized by changes in water color and odor when sebahagian riverside communities still use river water Kupang for everyday needs. This study aimed to analyze the water quality of the river Kupang based on river water quality standards in accordance with Regulation No. 82 of 2001, calculating the pollutant load Sungai Kupang and determine Air Quality Status and recommend management measures Pekalongan Kupang River water quality. Water quality measurements performed at 6 sampling points. Parameters measured and observed are the parameters of temperature, TSS, pH, DO, BOD, COD, chromium and Phosphate. For the analysis of the water quality of Sungai Kupang status using the pollution index and pollution load capacity using Qual2Kw.The results of research on water quality of Sungai Kupang shows COD parameter at some point has exceeded the standard quality. As for the parameters BOD at all points have exceeded the quality standards required. BOD value is the lowest concentration of 5.75 mg / l, while the highest value of BOD of 27 mg / l. The content of BOD increased presumably because the watershed is in from upstream to downstream received many waste dumps, while based on the status of water quality showed a decrease in water quality from upstream to downstream, which in part has been lightly polluted downstream. And also for the calculation of pollution loads Kupang River from upstream to downstream has increased, to the pollution load of TSS concentration amounted 20670.334 kg / day, while the COD concentration is equal to 16517.777 kg / day, and the BOD concentration is equal to 6618.643 kg /day.Keywords:  Water Quality, Pollution Load, Kupang RiverCara sitasi: Pohan, D.

Neuro-ethics is probably fastest growing part of applied ethics. The main thesis is that certain natural processes in brain and nerves produce certain moral, and immoral, behaviors. All these processes can be explained causally, and (if this is so) neuro-ethics might be the final result of neuroscience. There are some metaphysical and ethical pitfalls to be considered, however, like the (incorrect) conflation of causal explanation and rational justification in definingvalues, not only non-moral values but moral values as well. Certainly, the knowledge of how neurological processes function could help to enhance the quality of human life, not only in coping with defects but also in improving the so-called ?normal life?. This implies that neuroethics is instrumental, dealing with values which are instrumental as well. However, neuroethics, it seems, aspires to go further than that: to explain how goals come into existence and what their articulation should look like. All of this should be causally explained, or at least explainable; and the main focus of the paper is an analysis of this aspiration. The analysis refers to some important distinctions like the distinction between causes and reasons, explanation and justification, or the one between means and ends. At the end of the paper there is a section about applications, where some of the benefits and risks are summarily indicated, with a conclusion that neuroethics surely might help in advancing the overall quality of human life, individual and social.

The scientific problem of economics “Managing the quality of human life” is formulated on the basis of artificial intelligence, algebra of logic and logical-probabilistic calculus. Managing the quality of human life is represented by managing the processes of his treatment, training and decision making. Events in these processes and the corresponding logical variables relate to the behavior of a person, other persons and infrastructure. The processes of the quality of human life are modeled, analyzed and managed with the participation of the person himself. Scenarios and structural, logical and probabilistic models of managing the quality of human life are given. Special software for quality management is described. The relationship of human quality of life and the digital economy is examined. We consider the role of public opinion in the management of the “bottom” based on the synthesis of many studies on the management of the economics and the state. The bottom management is also feedback from the top management.

Subject. The article considers functioning and development of process flows of transportation and logistics system of a smart city. Objectives. The study identifies factors and dependencies of the quality of human life on the organization and management of stream processes. Methods. I perform a comparative analysis of previous studies, taking into account the uniquely designed results, and the econometric analysis. Results. The study builds multiple regression models that are associated with stream processes, highlights interdependent indicators of temporary traffic and pollution that affect the indicator of life quality. However, the identified congestion indicator enables to predict the time spent in traffic jams per year for all participants of stream processes. Conclusions. The introduction of modern intelligent transportation systems as a component of the transportation and logistics system of a smart city does not fully solve the problems of congestion in cities at the current rate of urbanization and motorization. A viable solution is to develop cooperative and autonomous intelligent transportation systems based on the logistics approach. This will ensure control over congestion, the reduction of which will contribute to improving the life quality of people in urban areas.

Service at the “Kelurahan” is a very important part in determining the success of development, especially in public service. The problem faced is the lack of skill level of the “Kelurahan” apparatus with the more dynamic demands of the community and the archive management system is still conventional and manual that is writing the identity of the archive into the book agenda, expedition, control card, and borrowed archive card, so it takes a more practical electronic system, effective and efficient so required to develop themselves in order to improve public services. Conventional administration and archive management must be transformed into cloud-based computing (digital), for which archiving managers should always be responsive and follow these developments and wherever possible in order to utilize for archival activities, with greater access expected archives are evidence at once able to talk about historical facts and events and be able to give meaning and benefit to human life, so archives that were only visible and readable at archival centers can now be accessed online, and even their services have led to automated service systems. Using Microsoft Access which its main function is to handle the process of data manipulation and manufacture of a system, this system is built so that the bias runs on Cloud which means Cloud itself is a paradigm in which information is permanently stored on servers on the internet and stored. The purpose of this program is the implementation of administrative management that has been based cloud computing (digital) and is expected to be a solution in managing the archive so that if it has been designed and programmed, it can be stored in the computer and benefi- cial to the “Kelurahan” apparatus and add in the field of management archives in the form of improving the quality of service to the community, can facilitate and scientific publications.

The assessment of groundwater is essential for the estimation of suitability of water for safe use. An attempt has been made to study the groundwater of selected areas of Punjab (Sheikhupura &amp; Sahiwal) and Sindh (Sindh, Jawar Dharki and Dharki), Pakistan. The results indicate that pH, color and odor were all within limits of WHO that is pH ranges 6.5–8.5, colorless and odorless, respectively. The high values of suspended solids were observed in the Sindh-1 and Dharki samples. Microbiologically only Sahiwal and Jawar Dharki were found fit for drinking purpose. Trace metals analysis of Sheikhupura-1 and Sindh-1 showed that values do not fall within limits of WHO for Iron. The ionic concentration analysis showed that high bicarbonate (HCO3-), ions are present in the samples of Sahiwal and Dharki; Sindh-1 and Jawar Dharki samples showed very high concentration for chloride ions, all samples were satisfactory level for sulphate (SO42-), sodium, magnesium and phosphate ions except samples of Sindh-1 and Jawar Dharki. High concentration of calcium and potassium ions was observed in samples of Sindh-1, while all other samples were found fit for drinking purposes in respect of nitrate, nitrite and ammonium ions. The high concentration of Fluoride was found only in Sheikhupura-2 samples.

Background: Dementia after stroke, particularly subacute period is often overlooked. Today the quality of human life is increasingly high, finding scales that have high value for detection of dementia in patients with stroke is increasingly interested. MoCA test is high sensitivity with mild dementia and identify more abnormalities of awareness caused by vascular, but MoCA have not been studied much in Vietnam. Objective: Assessing MoCA test in subacute stroke patients and compare MoCA versus MMSE in these patients. Subjects: 90 patients with subacute stroke period, these people are being treated at Department of cardiovascular internal medicine at Hue Central Hospital, from 7/2014 - 7/2015. Methods: cross-sectional description and analysis. Results: The mean age is 65.57 ± 13.38, accounting for 54.4% male and 45.6% female. Age, duration of illness has weak correlation with MoCA. The risk factors: hypertension, stroke ischemic transient, alcoholism, smoking, heart disease, diabetes, dyslipidemia related no statistical significance with MoCA. The proportion of dementia in subacute stroke according MoCA is 82.2%. The concordance between MoCA and MMSE was good (kappa = 0.684). Using DSM-IV criteria as the gold standard we found MoCA more valuable in the dementia diagnosis than MMSE (AUC 0.864 versus 0.774, p <0.05). Conclusion: The rate of dementia in stroke subacute period according MoCA is quite high. MoCA is valuable than MMSE in detecting dementia in patients with stroke subacute period, this scale is short, easy to implement so should put into using widely in clinical practice. Key words: MoCA test, subacute stroke, dementia
