Abstract

Kegiatan produksi dapat berjalan lancar diperlukan keputusan yang tepat. Banyak tujuan yang ingin dicapai sehingga diperlukan data-data yang lengkap. Dukungan data yang tidak pasti dan samar membuat keputusan perencanaan produksi tidak tepat. UKM furniture berusaha untuk mengoptimalkan sumberdaya yang ada supaya dapat tercapai tujuan secara maksimal. Supaya pengambilan keputusan dapat optimal maka menggunakan metode pendekatan model fuzzy goal programming (FGP). Kegiatan produksi menghasilkan lemari, bufet dan dipan. Jenis produksi lemari adalah lemari pintu 1, pintu 2, dan pintu 3, sedangkan jenis produksi bufet adalah lebar 1,0 meter, 1,50 meter serta 2,0 meter, serta jenis produksi dipan adalah ukuran 1,2 meter dan 1,6 meter, sehingga keseluruhan ada 8 variabel. Tujuan yang ingin dicapai adalah memaksimalkan pendapatan dengan memiminimalkan biaya tenaga kerja, biaya bahan baku dan waktu produksi. Berdasarkan analisis data untuk mencapai tujuan perencanaan produksi yang optimal, dengan pembatasan kemampuan sumber daya UKM furniture, maka persediaan kayu yang harus disiapkan setiap bulan sebesar 25,3 m3. Sedangkan hasil nilai fuzzy 0,98 mempunyai arti peluang keuntungan optimal akan dicapai sebesar Rp. 90.620.000,  merupakan keuntungan yang diterima oleh UKM furniture.

Abstract

Since its first operation in 2010, Bhakti Dharma Husada Regional Public Hospital (RSUD) has experienced an increase in patient demand for health services. Some services now require additional space. Moreover, there is a growing need for executive and VIP services. To address these needs, Bhakti Dharma Husada Regional Public Hospital is planning to enhance its services by constructing a new building. Based on the results of investment analysis obtained Net Present Value (NPV) of Rp. 1,373,606,103,022, Payback Period (PP) for 6.89 years, Internal Rate of Return (IRR) value of 17.39% is greater than the Minimum Attractive Rate of Return (MARR) value of 9.21% (IRR> MARR), Benefit Cost Ration (BCR) of 1.28, then the investment is declared feasible. In addition, based on the results of the sensitivity analysis, the investment feasibility limit is obtained, namely the development of the hospital becomes unfeasible if the service tariff is reduced by 15% or the operating costs are increased by 15% or the interest rate is increased by 13%.

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%.
