Kertas kerja ini membincangkan kajian literatur mengenai proses awal yang perlu dititikberatkan dalam pembangunan suatu GIS (Geographical Information System). Dalam pembangunan sistem maklumat geografi (GIS), proses penukaran data (data conversion) merupakan proses awal yang perlu dilalui untuk mencapai kepada tahap pangkalan data geografi yang bermutu tinggi. Proses ini juga biasanya merupakan sebahagian terbesar daripada keseluruhan projek GIS dan secara tidak langsung kos untuk proses tersebut juga adalah yang paling tinggi iaitu dalam lingkungan 60%. Dari segi terminologi pula, terdapat dua aspek proses penukaran dan di dalam kertas kerja ini salah satu aspek yang akan dibincangkan iaitu dari segi persediaan awal berkaitan dengan spesifikasi projek penukaran, spesifikasi data dan spesifikasi pentadbiran harus dilaksanakan sebelum proses penukaran (conversion) dapat dijalankan dengan lancar. Setiap sistem AM/FM pula, memerlukan kepada satu dasar tanah yang tepat, terkini dan selaras dengan tempat data fasiliti dirujuk secara geografik. Dengan lain perkataan, tanpa dasar tanah, sesuatu sistem pemetaan tidak boleh dikatakan sebagai satu GIS. Beberapa teknik perolehan dasar tanah dibincangkan dengan serba ringkas untuk membolehkan perhatian ditumpukan kepada masalah penyediaan dan pembersihan data fasiliti yang akan dirujuk terhadap dasar tanah ini kelak. Pembersihan data fasiliti adalah amat perlu supaya data yang dimasukkan semasa proses penukaran berada dalam keadaan baik dan tidak mendatangkan masalah semasa penggunaan kelak. Ini juga dapat menjimatkan kos pengguna dalam jangka masa panjang. Mutu maklumat yang akan ditukar juga perlu diambilkira.

In the development of a GIS, data conversion is the initial process that one has to undergoe in order to achieve a geographic of high quality. This process often constitutes to more than half of the total of a GIS project and indirectly the cost for this process is usually around 60%. In terms of terminology there are two aspects of data conversion in a GIS namely, conversion of analogue/manual geographic data to digital form which involves manual sources such as paper maps, drawings, digital form etc. and conversion from one GIS system to another GIS system of different format. In this paper only the first aspect will be discussed in depth regarding early preparations to be considered in the data conversion and this pertains to project specifications, data specification and administrative specifications. Every GIS requires a current, uniformly accurate landbase to which the facilities data can be geographically referenced. In other words, a computerised mapping system is nota a true GIS if it is not referenced to land base. Techniques on land base acquisition is disscussed in brief to allow the author to express in detail problems concerning the importance of data preparation and purification before the final conversion takes place. Data preparation and purification is viable so as not to input 'garbage' and 'output' garbage as well. Quality control on data to be converted should also be taken into consideration.

Abstrak --- Akselerasi pada jaringan kerja proyek yang sederhana biasanya dilakukan dengan prosedur manual yaitu dengan Critical Path Method (CPM) atau Project Evaluation and Review Technique (PERT). Pada dasarnya metode tersebut menggunakan pendekatan trial and error yang berguna untuk memperagakan logika akselerasi. Namun dalam persoalan jaringan kerja proyek yang lebih rumit dan membutuhkan kecepatan pengolahan data yang tinggi, analisis CPM/PERT akan mengalami kesulitan dan bahkan tidak memungkinkan lagi dilakukan dikarenakan ketergantungan kegiatan yang satu dengan yang lainnya serta perbedaan biaya dari kegiatan tersebut. Oleh karena itu, diperlukan suatu metode analisis yang dapat menentukan kombinasi nilai percepatan yang tepat untuk setiap kegiatan proyek. Seiring perkembangan zaman dan teknologi telah banyak program komputer yang dibuat khusus untuk memproses pengolahan data proyek, salah satu diantaranya adalah program aplikasi LINDO (Linier Interactive Discrete Optimizer). Berdasarkan perhitungan aplikasi metode program linier LINDO pada kasus proyek rehabilitasi SDN 16 Pinrang Sulawesi Selatan diperoleh biaya total minimum sebesar Rp 45.349.571,65.- untuk akselerasi dari 120 hari menjadi 70 hari serta didapatkan besarnya waktu percepatan yang tepat untuk masing-masing aktivitas.

Lack of project scheduling planning and ineffective control make the activity of a project less efficient. This will have an impact on the success of the project. This situation will result in delays and a decrease in the quality of work due to time constraints. Scheduling is important for determining the required activities and arranging a sequence and time frame to complete project activities on time. This study aims to optimize the scheduling of a moderate light rehabilitation project in the Badas Community Health Center building, Kediri Regency, where project start-ups are experiencing delays. The method used is Critical Path Method-Project Evaluation and Review Technique (CPM-PERT), which is a method to determine the duration of a project that can be completed and the percentage of its success. The analysis carried out includes calculation the duration desired acceleration and cost slope. Analysis results using CPM-PERT obtained critical path in: preparation activities (A), earthworks (B), structural work (D), 1st floor work (E), 2nd floor work (F), 3rd floor work (G), roof, ceiling and plank work (H), iron work (I), electrical work (L), floor and wall covering work (M) and finishing work (N). The normal duration of project completion is 140 days and costs Rp. 1,818,182,709, whereas with the CPM-PERT method the duration can be accelerated to 128 days (probability 99.99%) and required additional fee 8.1% or worth Rp. 146,719,664. Implementers can use it in optimizing scheduling and financing on the badas public health center building construction project.

Critical Path Method

Critical Path Method (CPM) dan Project Evaluation Review Technic (PERT) adalah metode yang banyak digunakan untuk membuat penjadwalan proyek. Salah satu kelebihan dari gabungan dua metode ini adalah untuk mengevaluasi waktu penyelesian proyek atau keterlambatan karena faktor–faktor yang tidak diperhitungkan sebelumnya. Sehingga alternatif mempercepat pelaksanaan waktu proyek (crashing project) menjadi salah satu alternatif yang dapat diandalkan seorang kontraktor. Untuk mengevaluasi proyek pemasangan saluran rumah berdasarkan analisis CPM diperoleh estimasi waktu penyelesaian selama 180 minggu dengan lintasan kritis proyek meliputi aktivitas A-B-C-E-F. Dari lamanya waktu penyelesaian, upaya percepatan dengan informasi estimasi tiga waktu utama yaitu to (waktu optimis), tp (waktu pesimis), dan tm (waktu yang memungkinkan) dan informasi waktu crashing setiap aktivitas dan besar biaya crashing, maka diperoleh waktu percepatan pemasangan SR menjadi 160 hari dengan mempercepat penyelesaian aktivitas B-C, dan C-E dengan total biaya crashing sebesar Rp. 2.350.000,-Kata kunci: crashing project, CPM-PERT, perumahan, penjadwalan

Presented method is applied to Project Management by using PERT-CPM critical paths to manage project risk. DMAIC framework applies stochastic techniques. Stochastic optimisation determines the critical paths. Every critical path is simulated and associated risks are calculated. Six Sigma process metrics are calculated against specified targets. Simulation results are analysed and sensitivity analysis is used to identify and quantify the main contributors to the variability of the project duration time. The critical paths are ranked and prioritised for management's attention based on their associated risk factors. The project was not implemented, so there no data for analysis. However, assuming that the project was implemented, a generic Project Control phase is applied.
