Abstract

Small-scale residential construction projects often experience delays due to weak schedule control and unstructured scheduling. This study aims to apply the Critical Path Method (CPM) to schedule the construction project of a Type 36 residential house at Grand Permata Hijau Housing, Samarinda City, to identify the critical path and determine the optimal completion duration. This research used a quantitative descriptive approach with a case study method. Project data, including the Cost Budget Plan (RAB) and initial schedule, were analyzed by constructing an Activity on Node (AON) network diagram, followed by forward pass and backward pass calculations. The CPM result indicates a potential reduction in project duration compared with the initial 120-calendar-day target. The resulting critical path consists of nine activities, including Preparation Work (A), Foundation Work (C), Concrete Work (D), Wall Masonry Work (E), Roofing Work (H), Ceiling Work (I), Wood & Frame Work (J), Painting Work (L), and Handover (O). This study proves that the CPM method is effective in optimizing scheduling time and can serve as a reference for time control in small-scale residential construction projects at the local level

Abstract

This study evaluates the feasibility of Yaka Photo & Studio in Tenggarong Seberang District from market, technical, and financial perspectives. The research is important due to the rising demand for photography services in non-urban areas, where many businesses operate without proper feasibility assessments, creating risks of financial loss and missed opportunities. A descriptive mixed-method approach is applied. Market analysis identifies target consumers and potential demand; technical analysis reviews location, facilities, and operational readiness; and financial analysis uses Net Present Value (NPV), Internal Rate of Return (IRR), payback period, and break-even indicators. The results show a strong market outlook with high demand and low competition. Technically, the business benefits from a strategic location, adequate equipment, and experienced staff that support smooth operations. Financially, the business is feasible, evidenced by a positive NPV of IDR 141,464, an IRR of 10% exceeding the 8% discount rate, a 2.3-year payback period, and a BEP of 61%, which remains below the general feasibility threshold of around 70%. These findings enrich the literature on non-urban creative industries and highlight the relevance of digital marketing. Practically, the results offer guidance for local entrepreneurs in improving digital promotion and assessing financial feasibility for sustainable development

Abstract

This study analyzes the business feasibility of a car rental company in Samarinda from financial and marketing perspectives. The increasing mobility needs of the people in Samarinda have driven the growth of the transportation service industry, including car rentals, making this analysis timely and relevant. A mixed methods approach was applied, combining qualitative interviews and quantitative financial data. Financial feasibility was evaluated using Net Present Value (NPV), Internal Rate of Return (IRR), Payback Period (PP), and Net Benefit-Cost Ratio (Net B/C) indicators, supported by a sensitivity analysis to assess the business’s resilience to changes in the discount rate. The results indicate that PT Mitra Trans Bersaudara is financially feasible, with a positive NPV of IDR 142,498,446, an IRR of 13.87% exceeding the 10–12% discount rate, a Net B/C ratio of 1.069, and a Payback Period of 2.33 years. Marketing analysis through STP (Segmentation, Targeting, and Positioning) and the 7Ps Marketing Mix revealed key segments, including companies, government institutions, and upper-middle-class families, with a strong positioning as a trusted and professional service provider. This research contributes as a reference for future studies, a benchmark for car rental businesses, and a consideration for government policies in supporting the local transportation sector.
