Taman Budaya GWK dibangun di kaki pulau Bali di atas bukit kapur di desa Ungasan dengan jarak kurang lebih 6 km dari Bandara Internasional I Gusti Ngurah Rai. Taman Terdiri atas sebuah Patung yang berada di atas bangunan Pedestal pada ketinggian 144,64 m. Patung ini dikitari atraksi budaya sebagai pendukung obyek wisata dengan kegiatan bisnis. Apakah proyek ini layak secara financial ? Analisis finansial didukung data yang sebagian besar menggunakan metode Estimasi yang berkaitan dengan aspek pembiayaan, menggunakan program analisis risiko @Risk. Sedangkan metode ramalan yaitu dengan metode dekomposisi, regresi linier dipergunakan dalam hal peramalan akan kedatangan wisatawan. Hasil penelitian ini adalah: Secara financial proyek tersebut di atas, NPV, IRR dan BCR dinyatakan layak dengan probalilitas antara 50 % hingga 55 %. NPV rata-rata adalah Rp. Rp. 116.162.424.523,10, dengan probabilitas 20 % dan sensitivitas yang paling kuat pengaruhnya adalah bangunan pedestal dan patung yaitu - 80 %. Distribusi nilai IRR berada dalam kisaran 16 % hingga 27 % dengan nilai rata-rata 20 %. Korelasi sebesar 10 % dari kedatangan wisatawan. Nilai BCR terdistribusi antara 0,79 hingga 1,73 dengan rata-rata 1,20. Probabilitasnya hanya 30 % dengan korelasi yang paling besar pengaruhnya adalah bangunan pedestal dan patung sebesar - 82 %.

Evaluation of building design consultant performance is needed, becausemost of strategic decisions and project costs depend on the consultant performancethat is implemented in project design documents. The Analytical Hierarchy Process(AHP) method can be used as a reference for assessing the consultant performancein more detail and measurable. The hierarchy of assessment criterions was obtained from the interview in whichthe respondents were building design experts and it was combined with relevantliteratures. The analysis using the AHP method was conducted to compare theimportance level of criterion using pair-comparison matrixes. The weight ofcriterion and sub criterion were calculated by using eigen vector.The result of this study indicates that Quality of Design Document is the mostimportant criterion (41,8%), followed by Relevancy with Term Of Reference(26%), Time Schedule ( 17,7%), and Design Cost (14,5%), which presented atlevel 2. At level 3, Consistency of Design Document is the most important criterion(13,9%), followed by Constructability of Design Document (11,3%), Accuracy ofDesign Document (10,6%), and so on. The last criterion, which has the smallestassessment weight, is the Goal Achievement of the Preparation Phase (4,6%). Atlevel 4, Consistency among Engineering Drawing Document, Specification andCost Estimate is the most important sub-criterion (6,9%), followed by RationalTime Schedule (5,8%), Equivalency of Remuneration with Project Requirement(5,7%) and so on. The last criterion is positioned by Explanation of ConstructionMaterial, which has the smallest assessment weight (0,7%). Based on theassessment hierarchy, which has been completed with global weight of allcriterions, hence the tables of assessment system for building design consultantperformance can be made. Accordingly, the consultants can be classified accordingto their performance levels.

Setelah krisis moneter, perkembangan di bidang konstruksi khususnya di Indonesia telah mengalami kemajuan. Para penyedia jasa kontruksi bersaing untuk mendapatkan kepercayaan dari pengguna jasa konstruksi. Diantaranya dengan menggunakan ready mix concrete (beton siap pakai) untuk mempercepat penyelesaian proyek dan untuk menjamin agar mutu yang dihasilkan sesuai dengan rencana. Kondisi ini menyebabkan kebutuhan akan beton siap pakai terus meningkat sehingga diperlukan perencanaan persediaan material yang ekonomis yang dapat menjamin kelancaran proses produksi. Penelitian ini membahas perencanaan persediaan material yan ekonomis pada industri beton siap pakai di PT. Sarana Beton Perkasa. Untuk peramalan permintaan selama dua tahun terhadap mutu beton K-225, K-250, K-275, K-300, dan K-350, perencanaan kebutuhan total bahan baku, serta analisis biaya. Metode riset operasi digunakan untuk mendapatkan harga bahan baku yang lebih ekonomis dari sekian banyak sumber pembelian bahan baku. Selain itu, metode Economic Order Quantity (EOQ) digunakan untuk mendapatkan biaya total yang ekonomis dalam proses produksi ready mix concrete. Hasil analisis menunjukkan bahwa perkiraan permintaan beton siap pakai dalam dua tahun peramalan (2014 dan 2015) adalah 4.745 m3 untuk mutu beton K-225, 14.284 m3 untuk K-250, 803 m3 untuk K-275, 53.200 m3 untuk K-300, dan 27.244 m3 untuk mutu K-350. Sementara itu, diperlukan 36.510 ton semen, 69.438 m3 pasir, 45.404 m3 koral, 77.276 liter retarder, serta 18.015.548 liter air untuk memproduksi ready mix concrete. Sehingga, total biaya yang harus dikeluarkan untuk memproduksi ready mix concrete selama dua tahun adalah sebesar Rp. 157.488.069,00.

Pengelolaan finansial seringkali kurang dicermati oleh kontraktor, namun kontraktor cenderung berusaha untuk mendapatkan keuntungan yang sebanyak-banyaknya. Modal kerja dari realisasi penerimaan sangat ditentukan oleh cara pembayaran yang telah ditetapkan dalam kontrak konstruksi. Penentuan sistem pembayaran yang tepat dapat mengurangi resiko kekurangan modal kerja. Tujuan penelitian ini adalah mencari alternatif sistem pembayaran yang paling menguntungkan bagi kontraktor. Penelitian dilakukan pada Proyek Peningkatan Struktur Jalan Cekik-Batas Kota Negara. Time Schedule proyek diasumsikan sebagai kondisi penjadwalan EST dan kondisi penjadwalan LST didapatkan dari pengolahan data dengan membuat uraian dan urutan setiap kegiatan dalam aktivitas proyek sehingga dapat ditentukan durasi waktu tenggang untuk setiap aktivitas dengan metode PDM menggunakan bantuan software Microsoft Project. Kemudian dibuat analisis cash flow untuk beberapa alternatif yaitu sistem pembayaran bulanan dan termin progress 25% dengan masing-masing uang muka sebesar 0%, 10%, 15%, dan 20% dalam kondisi penjadwalan EST dan LST. Dari ke enam belas alternatif sistem pembayaran yang ditinjau akan dicari besarnya keuntungan yang akan diperoleh. Hasil analisis data menunjukan bahwa sistem pembayaran yang paling menguntungkan adalah sistem pembayaran bulanan dengan uang muka 20% pada kondisi penjadwalan EST yang menghasilkan nilai penutupan akhir sebesar Rp. 3.062.755.359,01 dan persentase keuntungan 9,80%.

In construction businesses, it is important to understand the differences between standard costs and the actual costs. Comparing or to find the differences between actual and standard cost in the term of accounting is known as variance analysis. Real cost is the cost of material and labour that actually paid by the company. Standard cost is the cost that calculated based on the quantity of work items multiplied by coefficient of BOW and furthes analysis multiplied again by standard price from city government of public labour 2004. The material price variance is calculated is caused by comparing real material price with the standard ones. The difference happened because by the reality that the company bought material higher or lower price than the standard material price. The total bought of material price variance can be calculated by multiplying (unit) item per item material price variance with the actual quantity. Material quantity or use variance is the differences that happened because the company uses the material more or less quantity than standard quantity in the production process. The total amount of material quantity or use variance can be calculated by multiplying the material quantity variance with the standard material price per item. The calculation of variance from material price revenled that 0.38%, material quantity variance 19.04% and the total amount of material price variance is 18.60% in relation to standard material cost. Labour cost variance is about 62.01% againsts standard labour cost. The total variance of cost and labour price is 36.03% againsts standard cost and labour price. If the calculation considered the indirect cost, the total variance will be 18.90%. Also if taxes is added in the calculation the total variance will be 13.82% of the standard cost.
