Applied Water Science (2020) 10:165 https://doi.org/10.1007/s13201-020-01185-4 ORIGINAL ARTICLE Development of an erosion model for Langat River Basin, Malaysia, adapting GIS and RS in RUSLE Md. Rabiul Islam1 · Wan Zurina Wan Jaafar2 · Lai Sai Hin2 · Normaniza Osman3 · Md. Razaul Karim2 Received: 4 April 2018 / Accepted: 30 March 2020 / Published online: 16 June 2020 © The Author(s) 2020 Abstract This study is aimed to predict potential soil erosion in the Langat River Basin, Malaysia by integrating Remote Sensing (RS) and Geographical Information System (GIS) with the Revised Universal Soil Loss Equation (RUSLE) model. In RUSLE model, parameters such as rainfall erosivity factor (R), soil erodibility factor (K), slope length and steepness factor (LS), vegetation cover and management factor (C) and support practice factor (P) are determined based on the input data followed by the spatial analysis process in the GIS platform. Rainfall data from 2008-2015 are collected from the 29 rain gauge stations located within the study area. From the analysis, the magnitude of RUSLE model obtained corresponding to the parameter R, K, LS, C and P factors is varied between 800 to 3000 MJ mm ha − 1 h− 1 yr− 1, 0.035–0.5 Mg h MJ− 1 mm− 1, 0–73.00, 0.075–0.77 and 0.2–1.00, respectively. Findings of this study indicates that based on the calculated RUSLE parameter values, about 95% of the Langat River Basin area have been classifed as a very low to a low erosion vulnerability. Findings of this study would greatly benefts a decision maker in proposing a suitable soil management and conservation practices for the river basin. -

Three sets of topographical maps for three different years (1969, 1976 and 1993) were digitized and rectified and type of changes for the non-stable reaches were defined by superimposing the digital maps of all dates. The results indicate that, middle stream is the most unstable reach followed by upstream which has a few unstable sub-reaches while the downstream shows no changes during the study period. Type of most of the lateral changes for upland reach was meander progression and for middle stream meander progression and avulsion construct most of changes. The middle stream of the channel was identified as the most unstable reach with an average 11.81% change in its sinuosity index. Meanwhile, the upland and downstream of the channel were behaving as more stable reaches with an average 6.92% and 8.47% changes in their sinuosity, respectively. -

PLANNING MALAYSIA: Journal of the Malaysian Institute of Planners VOLUME 18 ISSUE 3 (2020), Page 241 – 250 EVALUATION OF LEVEL OF SERVICE (LOS) ON ROUTES OF SMART BUS IN KAJANG, SELANGOR Nur Shazreena Mat Shukri1, Zakiah Ponrahono2, Yakin Nur Sunoto3, & Wan Noratikah Wahidah Wan Ghazali4 1,2,3,4 Department of Environment Faculty of Forestry and Environment UNIVERSITI PUTRA MALAYSIA Abstract Level of service (LOS) is a method used for the development of transportation infrastructure designations based on a specific analysis. The concept of LOS lies on the importance of an assessment of roadway operational performance services for the improvement of bus service delivery. A high performance of bus service delivery could relatively influence the satisfaction level of its users. This study assesses the LOS of three main designated routes of SMART buses in Kajang Selangor (KJ01, KJ02, and KJ03). The SMART buses are free buses provided under a free transit programme which aims to encourage people to use public transportation. An on-board survey and inventory observation were employed to collect the data. Findings indicate that KJ01, KJ02, and KJ03 fall under the category of LOS D considering the attributes of service frequency, service hours, passenger load/thresholds, and speed of bus. The discovery may serve as a useful guidance for the development of a comprehensive plan for LOS to be coordinated in improving the service quality of bus transportation.

The Perception of Planning Stakeholders in the Implementation of Kajang Municipal Council Local Plan 2020 with Reference to Public Facilities Sector
THE PERCEPTION OF PLANNING STAKEHOLDERS IN THE IMPLEMENTATION OF KAJANG MUNICIPAL COUNCIL LOCAL PLAN 2020 WITH REFERENCE TO PUBLIC FACILITIES SECTOR BY NUR AULIA BT ROSNI A thesis submitted in fulfilment of the requirement for the degree of Master of Science (Built Environment) Kulliyyah of Architecture and Environmental Design International Islamic University Malaysia JULY 2015 ABSTRACT The study examines the implementation of the Kajang Municipal Council Local Plan 2020 with reference to public facilities sector. Local plan is the document containing policies that guide the way of development planning and Local governance. It is the lowest tier of administrative authority as required by the Town and Country Planning Act 1976 (Act 172) and Local Government Act 1976 (Act 171). It forms the basis of the development plan of a locality in Malaysia. However, the efficiency of its implementation is questioned by those who have an interest in the planning practice, namely the stakeholders. The public facilities sector was chosen as the research subject, because it has been regarded by the Federal Department of Town and Country Planning Peninsular Malaysia as one of the most important indicators of sustainable development. The planning principles for public facilities provision has been categorized into four scopes, namely (i) Availability, (ii) Quantity, (iii) Location, and (iv) Condition. Data collection was conducted in three main settlement areas within Mukim Kajang - Kajang Town, Bangi Town and Bandar Baru Bangi. The research methods comprised of field survey, observation and document analysis, wherein all the data were analysed using SPSS software. The key findings of this study include (i) Lack of Stakeholders Involvement in Decision Making Process, (ii) Lack of Awareness among the Local Community, (iii) Issues in Public Facilities Monitoring and Maintenance, and (iv) Inability to implement the Public Facilities. -

In order to support restoration and rehabilitation works of Sungai Langat, sufficient information on physical river characteristics are needed. The use of Geographical Information System (GIS) to map active channels and to categorised the reach according to sinuosity indices over time is encouraging. Total channel length in year 1996 reduced by about 16% from 1973. Avulsion and cut-off were observed at least at six stretches along the river. The sinuosity index (SINDX) varies from 0.61 to 2.31 in 1973 and 0.04 to 2.31 in 1996. At downstream, the channel tends to be more stable and straighter with SINDX < 2.5. This trend of river channel changes can be used as basis for evaluating river restoration works. Keywords: Restoration; Geographic Information System; Channel Changes; Sinuosity Index.

Waste Management in the City of Shah Alam, Malaysia
Waste Management and the Environment IV 605 Waste management in the city of Shah Alam, Malaysia D. B. Omar Faculty of Architecture, Planning and Surveying, Universiti Teknologi MARA 40450 Shah Alam, Malaysia Nazrul Hisham bin Osman City Council of Shah Alam 40000 Malaysia Abstract Malaysia has been undergoing rather rapid urbanisation since the beginning of the 20th century. The level of urbanisation increased from 55.1 per cent in 1995 to 61.8 per cent in 2000, 63 per cent in 2005 and is expected to increase to 63.8 by 2010. The total population of Malaysia was 26.75 million in 2005 and is expected to increase to 28.96 million by 2010. This increase leads to more solid waste. The Klang Valley is the most urbanised region with 45 per cent of Malaysian urban centres being located here. The city of Shah Alam is one of the major centres in the Klang Valley and is a developing new town. Solid waste management is a major problem in the city of Shah Alam and new strategies are needed which aim at involving all citizens and achieving a sustainable environment. The City Council of Shah Alam requires waste compositional information at the local level to plan, implement and monitor waste management schemes that will enable them to meet their contribution to the national targets. This paper will discuss the current situation in the city of Shah Alam and the National Strategic Plan for Solid Waste Management. Keywords: urbanisation, population, solid waste management, citizens, sustainable environment. 1 Introduction Malaysia is now at the mid-point of its journey towards becoming a developed country by 2020. -

Map Asia 2003 Water Resources GIS Application in Evaluating Land Use-Land Cover change and its Impact on Hydrological Regime in Langat River Basin, Malaysia* Noorazuan M. H School of Social, Development & Environment, UKM Bangi (now on study leave at School of Geography, University of Manchester, UK) Ruslan Rainis Geoinformatic Unit, Geography Section, School of Humanities Universiti Sains Malaysia, 11800 Penang. E-mail: [email protected] Hafizan Juahir, Sharifuddin, M.Zain Department of Chemistry, Universiti Malaya, KL Nazari Jaafar Department of Geography, Universiti Malaya, KL Abstract GIS-based multi-temporal land use data provides a historical vehicle for determining and evaluating long term changes of land use due to urbanization. Along with the concurrent daily streamflow and precipitation records, the impact of land use change on the rainfall-runoff relationships has been explored in Langat River Basin. The basin is located at southern of the heart of Malaysia i.e. Kuala Lumpur, mentioned to be the most rapid semi-urban basin that experienced land use and land cover changes due to the onslaught of development. This article will highlights the evaluation of land use change result and how this outcome could affects the rainfall-runoff relationships. The study revealed that the landscape diversity of Langat significantly change after 1980s and as the result, the changes also altered the Langat’s streamflow response. Surface runoff has increased from 20.35% in 1983-88 to about 31.4% of the 1988-94 events. Evidence from this research suggests that urbanisation and changes in urban-related landuse- landcover (LULC) could affect the streamflow behaviour or characteristics. -
