Abstract

Delays in project implementation are caused by a lack of good control so that it affects the cost and completion time. The purpose of the study is to determine or predict how much a project will cost at the time of implementation and to determine the effectiveness of project control using the Earned Value Method. Aspects of project implementation time in weeks 2,4,5,9,11,13,16,17, 18,20,21,24 are slower than the planned schedule, this is indicated from the Schedule Variant (SV) indicator. While the performance of the project implementation time in week 3,6,7,8,10,12,14,15,19,22 is faster than the plan schedule, this is indicated by the Schedule Variant (SV) is positive. While the cost performance aspects of project implementation from week 6,9,11,13,17,19,22,23 incurred costs greater than the plan cost, this is indicated from the Cost Variant (CV) indicator is negative. Whereas in weeks 7,8,10,12,14,15,16,18,20,21, 24 incurred costs less than the plan cost, this is indicated by a positive Cost Variance (CV) indicator. The calculation results obtained from the effectiveness value of 1.603 for controlling the cost and time of the project using the Earned Value Method. In other words, the results of the effectiveness value greater than 1 (one) can be said to control the construction project of the Situbondo Regency bagor bridge very effectively using the Earned Value method.

Abstract

This study aims to analyze the suitability between the type of road damage and the budget costs incurred on provincial roads in the Madura region. The research method used road condition survey and questionnaire distribution to contractors, consultants, budget users, and local communities. Data analysis was done descriptively qualitatively, including the type, volume, and location of road damage. The results showed that the three most common types of road damage were cracks, potholes and raveling. The total area of damage identified was 261.95 m², with a repair cost of Rp 57,586,900. This research emphasizes the importance of detailed road defect analysis and appropriate budget allocation to improve repair efficiency and support the region's economic activity. The findings conclude that detailed road defect analysis and budget efficiency can improve road quality and support mobility and economy in the Madura region. The results provide a basis for local governments to plan road infrastructure improvements more effectively and efficiently.

Abstract

The aim of this research is to analyze the feasibility of investing in North Surabaya Hospital, Bulak District, Surabaya City with the parameters Net Present Value, Internal Rate of Return, Benefit Cost Ratio (BCR) and Payback Period. This research focuses on the North Surabaya Hospital which was built by the Surabaya City Government Health Service with a budget for 2026. The research instruments used were interview guidelines and observation sheets, with data collection procedures via location with related parties in the construction of the hospital, site observation, as well as documentation that includes primary and secondary data. Based on investment analysis of North Surabaya Hospital and evaluation of sensitivity to operational costs and potential income, the conclusion obtained is: Alternative 1 is feasible because it produces an NPV value of Rp. 211,014,227,005, IRR of 9.85%, BCR of 1.23 and PP of 7.69 years, but will be sensitive to the point that it is not feasible if there is an increase in hospital operational costs above 2.05% or a decrease in hospital service levy rates above 1.39% . Alternative 2 is not feasible because it produces an NPV value of Rp. 28,416,192,984, IRR of 6.57%, BCR of 1.14 and PP of 8.34 years, but it will be sensitive and feasible if there is a decrease in hospital operational costs above 7.73% or an increase in hospital service levy rates above 5.59%. Alternative 3 is not feasible because it produces an NPV value of Rp. 66,444,241,124, IRR of 7.30%, BCR of 1.16 and PP of 8.20 years, but it will be sensitive and feasible if there is a decrease in hospital operational costs above 5.7% or an increase in hospital service levy rates above 4.08%. Alternative 4 is feasible because it produces an NPV value of Rp. 166,294,504,181, IRR of 9.26%, BCR of 1.20 and PP of 7.70 years, but it will be sensitive to the point of being unfeasible if there is an increase in hospital operational costs above 0.15% or a decrease in hospital service levy rates above 0.10%.

Abstract

Air merupakan sumber daya alam yang sangat vital dan diperlukan untuk menentukan keberlanjutan kehidupan seluruh makhluk hidup di muka bumi ini. Masalah yang dihadapi adalah sistem air bersih ke daerah tempat tinggal penduduk tidak lancer. Dibutuhkan jaringan distribusi, pengelolaan sistem air bersih yang baik serta mampu melayani kebutuhan air bersih bagi penduduk. Demi mewujudkan hal tersebut maka dibutuhkan investasi yang cukup besar berupa penambahan kapasitas sistem penyediaan air baku. Berdasarkan latar belakang yang disebutkan, maka judul dari penelitian ini adalah Analisis Kelayakan Investasi Sistem Air Bersih Perumda Air Minum Wae Mbeliling, Kecamatan Lembor. Metode penyelesaian dalam perhitungan ini untuk Analisis Investasi Kelayakan dengan menggunakan metode Nett Present Value (NPV), dan metode Internal Rate of Return (IRR). Dari hasil analisis di peroleh Diperoleh nilai NPV sebesar Rp. 678.904.405.208 (NPV > 0).  Jadi investasi pengembangan kapasitas produksi dan jaringan air bersih Perumda Air Minum Wae Mbeliling, Kecamatan Lembor, layak untuk diteruskan. Nilai NPV yang positif atau lebih besar dari (> 0) menunjukkan bahwa penerimaan lebih besar dibandingkan dengan nilai yang diinvestasikan. Diperoleh nilai IRR 15,61 % > 10 % (tingkat bunga minimal yang diharapkan), maka investasi pengembangan kapasitas produksi dan jaringan air bersih Perumda Air Minum Wae Mbeliling layak untuk dijalankan.
