Community engagement is needed in the people approach of development. Information sharing and public consultation are not enough.
A case study among the riverside communities living in Yogyakarta city indicated that these communities need to move out of poverty and destitution through coaching and mentoring by various experts, and at the same time they would assure the ecosystem functioning of urban rivers. ABSTRACT Restorasi sungai-sungai perkotaan telah bergeser dari peningkatan fisik dan ekologis menjadi lebih berorientasi pada sosial dan ekonomi. Keterlibatan masyarakat dibutuhkan dalam pendekatan manusiawi pembangunan. Pemberian informasi dan konsultasi public tidak cukup studi kasus pada komunitas-komunitas yang hidup di pinggir sungai di kota Yogyakarta menunjukkan bahwa komunitas tersebut perlu mengentaskan diri dari kemiskinan dan keterbelaknagn dengan bantuan ahli, dan pada saat yang sama menjaga fungsi ekosistem sungai-sungai perkotaan. Arnellya Fitri 2015-09-01 Full Text Available Daerah Aliran Sungai (DAS Belik merupakan salah satu Daerah Tampungan Air (DTA yang berada di daerah perkotaan Kabupaten Sleman.
Akibat alih fungsi lahan pertanian menjadi lahan pemukiman yang padat menyebabkan semakin berkurangnya area resapan air hujan. Kurangnya area resapan air hujan menyebabkan kapasitas saluran drainase Sub Daerah Aliran Sungai (DAS Belik pada saat hujan tidak mampu menampung air sehingga banjir di sekitar saluran drainase terjadi. Tujuan penelitian ini untuk memberikan solusi dengan menggunakan konsep zero run-off dalam upaya mencegah genangan banjir di perkotaan yang kurang memiliki ruang terbuka hijau dan area resapan air hujan. Kajian debit banjir yang dilakukan pada sungai Belik menggunakan metode rasional dan metode SCS CN yaitu metode yang digunakan dalam penentuan debit puncak pada satu kejadian hujan. Perhitungan debit diperlukan untuk mengetahui besar limpasan maksimum pada drainase saluran DAS Belik. Metode hidrograf SCS CN menggunakan parameter tekstur tanah, tebal hujan, CN wilayah, retensi potensial maksimum air oleh tanah, dan kedalaman hujan efektif. Sedangkan metode rasional menggunakan parameter koefesien aliran, intensitas hujan, dan luas daerah pengaliran dalam menghitung debit limpasan.
Keseluruhan hasil perhitungan kedua metode melebihi besar debit pengukuran langsung menggunakan Metode Slope Area, artinya keseluruhan hasil menunjukkan banjir atau limpasan permukaan yang melebihi kapasitas drainase.Kata kunci. Limpasan permukaan, metode SCS CN, metode rasional, zero run-off Belik Watershed is one of the Water Catchment Areas located in urban areas of Sleman District. Land conversion from agricultural to residential area cause the descending of rain water catchment area. Lack of rain water catchment area can cause drainage channel capacity of Belik sub zone cannot hold rain water, so that flooding occurred around the drainage channel.

Budi Prayitno 2013-07-01 Full Text Available ABSTRAK Permukiman tepian sungai di Banjarmasin secara alami merupakan permukiman berbasis pada alam dan budaya huni sungai, saat ini mengalami degradasi kualitas kehidupan dan alamnya. Hal ini diakibatkan oleh bencana kebakaran, banjir dan tinggi resiko terjadinya urban heat island. Secara konfigurasi keruangan tidak terjadi hubungan dan keterpaduan antara ruang arsitektur dan infrastruktur kawasan yang berbasis daratan dan perairan. Fenomena yang terjadi adalah kepadatan, hubungan kawasan darat dan sungai yang lemah serta degradasi kualitas lingkungan.
Selain itu kenyamanan termal kawasan pun sangat rendah, yaitu: aliran angin yang tidak lancar, kelembaban cukup tinggi dan suhu yang tidak nyaman. Penelitian ini mencoba melakukan eksperimen melalui pendekatan simulasi permibilitas ruang dan kenyamanan termal dengan menggunakan metode analisis ruang dengan program Space Syntax dan metode analisis kenyamanan termal dengan program Envimet.
Penelitian ini membandingkan kondisi eksisiting dan usulan model arsitektur permukiman kampung beringkat yang berbasis arsitektur permukiman vernakular tepi sungai Banjarmasin. Kesimpulan dari penelitian ini adalah melalui pendekatan permibilitas keruangan yang mensimbiosiskan konfigurasi antara ruang darat dan air serta arsitektur kawasan dapat ditingkatkan kinerja kejelasan keruangannya tetapi secara kenyamanan termal tidak menunjukkan peningkatan kinerja secara signifikan karena morfologi kawasan yang relatif datar dan dengan proporsi ketinggian rata-rata bangunan yang rendah sehingga tidak terbentuk jalur pergerakan angin sebagai sarana ventilasi dan kenyamanan termal kawasan.

Hasmadi, I.M.; Pakhriazad, H.Z.; Norlida, K. 2011-01-01 The Sungai Pulai Mangrove Forest Reserve (SPMFR) is the largest reverin mangrove system in Johore.
In 2003 about 9,126 ha of the Sungai Pulai mangrove was designated as a RAMSAR site. RAMSAR sites are wetland areas that are deemed to have international importance and are included in the List of Wetlands of International Importance. The SPMFR plays a significant socio-economic role to the adjacent 38 villages. Satellite remote sensing is a useful source of information where it provides timely and complete coverage for vegetation mapping especially in mangroves where the accessibility is difficult. This study was carried out to identify and map land cover types using SPOT-4 imagery at the Sungai Pulai-RAMSAR site and its surrounding areas. Through unsupervised classification technique a total of seven classes of land cover type were mapped, where about 90% mapping accuracy was gained from the accuracy assessment. Later, vegetation densities were classified into five levels namely very high, high, medium, low and very low based on crown density scale using vegetation indices model such as NDVI, AVI and OSAVI.
Results from NDVI and OSAVI model were almost similar but AVI model detected more on medium vegetation which did not show the real ground condition. The study concludes that SPOT-4 imagery was able to discriminate mangrove area clearly from other land covers type. Vegetation indices model can be used as a tool for mapping vegetation density level in the SPMFR and its surrounding area.
Therefore VIs models from remote sensing are useful to monitor and manage the mangrove forest for sustainable management and preserve the SPMFR as a RAMSAR site in Peninsular Malaysia. (author).

Generally 65% of total fatty alcohols determined were short chain compounds (C 12 - C 20 ) derived from marine organisms, 14% were long chained compounds (C 21 - C 24 ) input of terrestrial plants and the rest were branched compounds from bacterial activity. C 16 compound dominated all the sampling stations with concentrations ranged from 29.69 to 164.35 μgg -1 dry weight which constitute 32% of total fatty alcohols. Short chain/long chain fatty alcohols ratio Σ(C 12 - C 20 )/ Σ(C 21 - C 22 ) of each sampling stations had the value 1; indicating high content of short chain compounds from marine sources. Meanwhile, Alcohol Source Index (ASI) calculated using C 22 / C 14 and C 22 / C 16 ratios. C 22 / C 14 ratio showed that stations Kp1, Kp2, Kp5 and Kp6 had a value 1 indicating the amount of C 22 was higher than C 14. Ratio of C 22 / C 16 showed that all the sampling stations dominated by C 16 compared to C 22.
The estuary of Sungai Kapar, Selangor was dominated by short chain fatty alcohols (C 12 - C 20 ) especially C 16 compound rather than long chain fatty alcohol (C 21 - C 24 ). (author). Samuel, Y. M.; Saad, R.; Muztaza, N. M.; Saidin, M. M.; Muhammad, S.
2018-04-01 Magnetic and geotechnical methods were used for shallow subsurface soil characterization at Sungai Batu, Kedah, (Malaysia). Ground magnetic data were collected along a survey line of length 160 m long at 2 m constant station spacing, while soil drilling using hand auger was conducted at 21 m on the survey line using 0.2 m sampling interval drilled to a depth of 5 m. Result from the processed magnetic profile data shows distribution of magnetic residuals in the range of -4.55 to 1.61 nT, with magnetic low (-4.55 nT to -0.058 nT) and were identified at distances 4 m, 10 to 16 m, 20 to 26 m, 58 m, 82 m, 104 to 106 m, 118 m, and 124 to 140 m. The magnetic lows are attributes of sediments. The result from the soil drilling shows sticky samples with variable sizes, greyish to brownish / reddish in colour, and some of the samples show the presence of shiny and black spots.
The characteristics of the samples suggest the soil as a by-product of completely weathered rock; weak with high water content and classified as Grade V soil. The study concludes; integration of geophysical and geotechnical methods aided in characterizing the subsurface soil at Sungai Batu. The result was correlated with previous studies and confirms the importance of integrated approach in minimising ambiguity in interpretation.

Zal U'yun Wan Mahmood; Mei Wo Yii 2013-01-01 The purpose of this study was to estimate the sedimentation rate in the Sungai Linggi estuary using the constant initial concentration of unsupported or excess 210 Pb model and verified with 137 Cs method. Five sediment cores were collected on 25 January 2011 using gravity corer with the inner tube of 50 cm length and 7.5 cm diameter.
The total 210 Pb activities in the sediment cores profile at all sampling stations were varied and upper than those obtained for supported 210 Pb i.e. 226 Ra, indicated disequilibrium among 210 Pb and its grandparents in the 238 U decay series. Meanwhile, the lower 137 Cs activities were observed at all sampling stations due to no significant sources of 137 Cs releases were transferred into Malaysian marine. The estimation of sedimentation rate indicated the agreement of 210 Pb and 137 Cs method with a general presence of deep mixing in the Sungai Linggi estuary. Therefore, the apparent sedimentation rates calculated from 210 Pb profiles generally reflect the true value with the range from 0.70 to 1.97 cmyr -1.
High sedimentation rate was observed at some sampling stations which are located in river channel, estuary and closer to mainland. This suggested that land-use development, agriculture activities, channelization etc.

In February 2009, Hospital Tengku Ampuan Rahimah (HTAR) reported a cluster of typhoid fever among four children in the pediatric ward. We investigated the source of the outbreak, risk factors for the infection to propose control measures. We conducted a case-control study to identify the risk factors for the outbreak. A case was defined as a person with S.
Typhi isolated from blood, urine or stool and had visited Sungai Congkak recreational park on 27th January 2010. Controls were healthy household members of cases who have similar exposure but no isolation of S. Typhi in blood, urine or stool.
Cases were identified from routine surveillance system, medical record searching from the nearest clinic and contact tracing other than family members including food handlers and construction workers in the recreational park. Immediate control measures were initiated and followed up. Twelve (12) cases were identified from routine surveillance with 75 household controls. The Case-control study showed cases were 17 times more likely to be 12 years or younger (95% CI: 2.10, 137.86) and 13 times more likely to have ingested river water accidentally during swimming (95% CI: 3.07, 58.71). River water was found contaminated with sewage disposal from two public toilets which effluent grew salmonella spp. The typhoid outbreak in Sungai Congkak recreational park resulted from contaminated river water due to poor sanitation.
Children who accidentally ingested river water were highly susceptible. Immediate closure and upgrading of public toilet has stopped the outbreak.

As a conversation area, this catchment has an important role in maintaining the water availability of Ciliwung basin and for flood control in downstream area. Based on the collected flood data recorded from 1993 to 1996, 14.6% of flood events in downstream of Ciliwung basin were caused by delivery flood from upstream area. Evaluation of land use conversion in upstream of Ciliwung basin was carried out by comparing land use in 1989 and in 1998. Land use optimization was done using linear optimization to minimize the value of composite runoff coefficient. Technical approach of engineering treatment was used to. Nisar Ahmad 2015-07-01 Full Text Available The radon activity concentration and toxic elements have been assessed in drinking and irrigated water samples collected from different locations of Sungai Petani, Kedah, Malaysia. The water samples were collected from wells, streams and taps.
A calibrated alpha spectrometer RAD-7 (Model 2890 and Atomic Absorption Spectrometers (Perkin–Elmer, Model AAnalyst 200, Shimadzu, Model AA-700 were used to estimate radon activity concentration and toxic elements, respectively. Maximum average value of radon concentration among the various types of water sources was found 14.7 ± 1.44 Bq/l in well water used for drinking and irrigation and minimum was found 5.37 ± 0.58 Bq/l in tap water used for drinking. Contribution of radon in drinking water to indoor air and age dependent associated annual effective doses were calculated from the measured radon concentration and were found less than lower limit of recommended action level. The activity concentrations of Ni Pb Cd As Cr were found higher for streams water as compared to wells and tap water.
Values of radon concentration in well water were found higher than EPA recommended level and lower than WHO action level while the annual effective doses and level of toxic elements in water reported in this study were found lower than recommended level.

One of disease whisch is often transmitted through water is diarrhea. The quality of water consumed by the community must be fillfull for health. So, It becomes the important thing in preventing the incidence of diarrhea. The aim of this research was to determine the relationship between the quality of well water and the incidence of diarrhea on the community living along the riverside area of Bengawan Solo.
Method: This was an observational research using cross sectional design. The subjects of this research were 66 persons staying for each upstream and downstream of Bengawan Solo.The quality of well water was assessed based on the parameters for temperature, pH, Biochemical Oxygen Demand (BOD, total dissolved solid (TDS, and E. The occurrence of diarrhea was determined by interviewing. Data would be analyzed using chi-square test at 0,05 level of significance. Result: The result of this research showed that variables which had relationship (p-value. Pipin Supenah 2015-05-01 Full Text Available The aims of this study were to assess the water quality of the River Condong and Condong River Quality Statebased on physical, chemical and biological parameters. Sampling was carried out in seven stations with 3 repetitions at intervals of one month.
Water quality were analyzed descriptively by reference raw Water Quality Standard. Determination of the stateof water quality using methods Storet. Results of laboratory tests showed that the water quality of the River Condong exceed the Water Quality Standard Group II based on Government Regulation No. 82 of 2001 and in particular textile waste quality standard TSS, DO, BOD5, COD, NH3, sulfide, Cr (VI, phenols, oils and fats, Biological parameters using makrobentos diversity index (H ' obtained a low value that is from 0 to 1.7077. Quality state based Storet method, the value of -31. It can be concluded that the condition of physical, chemical and biological parameters, Condong River water showed waters not appropriate the Quality Standard for agricultural irrigation, freshwater fish breeding and infrastructure or water recreation facilities before and after the discharge of liquid waste of batik. Condong River quality state before and after the liquid waste of batik is heavily polluted.
Syamsidar HS 2017-06-01 Full Text Available This study aims to determine the optimum weight of chitin that used as biocoagulant of river water. The water sample is taken from Kajenjeng river and the chitin used for research are isolated from green mussels (Perna viridis shell powder through three steps such as deproteination by NaOH 3%, demineralization by HCl 1,25 N and depigmentation by NaOCl 4%.
Then, the obtained chitin are contacted into water with variation of 0,25 gram; 0,5 gram; 0,75 gram and 1 gram in an hour. The result showed that optimum weight of chitin for COD determination, total hardness, calcium and turbidity is 0,75 gram, while optimum weight of chitin for magnesium determination is 0,5 gram. Widayati Indarsih 2016-10-01 ABSTRACT Bedog River that flows along Wijirejo Village, Pandak, in Bantul has been indicated to be polluted by varieties of liquid waste including batik industry. The objectives of this research are: to determine the quality of batik liquid waste; the quality of Bedog River water from physical aspects (temperature, TDS, TSS; chemical aspects (pH, COD, BOD, Cu, Cr+6; and biological aspect (plankton; to measure participation of stakeholder and also to develop a management strategy to manage batik liquid waste so that it does not pollute the environment.This research use survey method, data collected by purposive sampling. Water sample is directly taken from batik liquid waste and from the Bedog River with six observation station: S1 is the location before the waste disposal point, located around Pedak Bridge; S2 (+ 350 m next to S1, S3 (+ 750 m next to S2, located at Pijenan Bridge, S4 (+ 400 m next to S3 and S5 (+ 250 m next to S4 is location that has been polluted by batik liquid waste, and S6 (+ 400 m next to S5 is an area that is no longer able to contain more additonal batik waste.
Chemical, physical and biological data is carried on in direct measurement in the field and at laboratory. Participation data of stakeholder data is carried on interview method using questionare.
Result analysis used in this research is qualitative descriptive.The result of this research shows that the quality of batik liquid waste has surpassed from the quality standard. The water quality at location S4 has been polluted shown by the COD point 28 mg/L (quality standard 25 mg/L and BOD point 4,8 mg/L (quality standard 3 mg/L. S4 is the location of which has highest density of batik industry. Both organic and inorganic materials inside batik liquid waste have increased COD and BOD of Bedog River. According to the plankton diversity index, the water of Bedog River has been polluted at S2, S3, S4 and S5 locations. S1 and S6 locations are not classified into the polluted area.
Batik liquid waste gives accumulatively effects to chemical and physical river ecosystem character, thus it decreases plankton diversity index which live in it. The grade of local government stakeholder participation generally (57,14% at middle category. The environment management strategy can be done by: improving participation of batik crafter both individually (by applying clean production and minimalizing waste and collectively (by building IPAL in cluster; improving participation of stakeholder; and choosing properly technology of waste water treatment (IPAL.
