SPATIAL PROJECTION OF LAND USE AND ITS CONNECTION WITH URBAN ECOLOGY SPATIAL PLANNING IN THE COASTAL CITY, CASE STUDY IN MAKASSAR CITY, INDONESIA
No full textThe arrangement of coastal ecological space in the coastal city area aims to ensure the sustainability of the system, the availability of local natural resources, environmental health and the presence of the coastal ecosystems. The lack of discipline in the supervision and implementation of spatial regulations resulted in inconsistencies between urban spatial planning and land use facts. This study aims to see the inconsistency between spatial planning of the city with the real conditions in the field so it can be used as an evaluation material to optimize the planning of the urban space in the future. This study used satellite image interpretation, spatial analysis, and projection analysis using markov cellular automata, as well as consistency evaluation for spatial planning policy. The results show that there has been a significant increase of open spaces during 2001-2015 and physical development was relatively spreading irregularly and indicated the urban sprawl phenomenon. There has been an open area deficits for the green open space in 2015-2031, such as integrated maritime, ports, and warehousing zones. Several islands in Makassar City are predicted to have their built-up areas decreased, especially in Lanjukang Island, Langkai Island, Kodingareng Lompo Island, Bone Tambung Island, Kodingareng Keke Island and Samalona Island. Meanwhile, the increase of the built up area is predicted to occur in Lumu Island, Barrang Caddi Island, Barrang Lompo Island, Lae-lae Island, and Kayangan Island. The land cover is caused by the human activities. Many land conversions do not comply with the provision of percentage of green open space allocation in the integrated strategic areas, established in the spatial plan. Thus, have the potential of conflict in the spatial plan of marine and small islands in Makassar City.Hlm. 95-11

ANALISIS ALIRAN FLUIDA PADA DESAIN AWAL CHAMBER SENSOR LABORATORIUM TERBANG DENGAN METODE CFD = FLUID FLOW ANALYSIS ON INITIAL DESIGN OF AIRBORNE LABORATORY SENSOR CHAMBER WITH CFD METHOD
No full textAbstrak Chamber sensor merupakan suatu ruang untuk menempatkan sensor parameter atmosfer yang diletakkan di dalam pod milik LSA. Desain chamber menentukan karakteristik aliran udara yang akan melewati chamber. Diharapkan dari desain tersebut diperoleh properties udara di dalam sama dengan properties udara di luar chamber. Karakteristik aliran udara tersebut dibutuhkan untuk keakuratan pengukuran sensor parameter atmosfer. Untuk itu telah dirancang desain awal dari chamber sensor yang akan digunakan pada pengembangan kegiatan penelitian Laboratorium Terbang. Penelitian ini dilakukan untuk menganalisis aliran fluida pada desain awal dari chamber tersebut. Metode yang digunakan yaitu Computational Fluid Dynamics (CFD) dengan bantuan software ANSYS. Proses analisis dimulai dengan membuat geometri chamber berbentuk airfoil dengan menggunakan CAD. Kemudian melakukan diskritisasi (proses meshing) dan set-up kondisi batas lalu dilanjutkan processing menggunakan ANSYS CFX. Dari hasil analisis didapatkan desain awal chamber belum sempurna, karena masih terjadi pelepasan aliran setelah melewati diffuser. Sementara untuk mengantisipasi pelepasan aliran pada Inlet chamber dapat dilakukan dengan membuat Inlet yang aerodinamis. Abstract Sensor chamber is a room to place the sensor of atmospheric parameters in the LSA's pod. The chamber design determines the characteristics of the airflow that will pass through the chamber. It is expected from the design to obtain the air properties inside as same as the air properties outside the chamber. Such airflow characteristics are required for the accuracy of atmospheric sensor measurement results. For that purpose has been designed the initial design of chamber sensors that will be used in the development of Airborne Laboratory. This study was conducted to analyze the fluid flow in the initial design of the chamber. We used Computational Fluid Dynamics (CFD) method with ANSYS software. The analytical process begins with creating an airfoil-shaped chamber geometry using CAD. Then we do the meshing process and set-up the boundary conditions then proceed using ANSYS CFX. From the analysis results obtained the initial design of chamber has been not perfect, because there was still release of flow after passing diffuser. Meanwhile, to anticipate the release of flow in the Inlet chamber can be done by making the aerodynamic Inlet.Hlm. 39-46:Il.; 9,7 Cm
