Abstract

Background: Coconut shell waste in rural agricultural communities represents a largely underutilised resource due to limited processing knowledge, lack of organised entrepreneurship, and absent institutional support. Adabai Village, East Seram Regency, Maluku Province, produces significant quantities of coconut shells that are routinely discarded or burned, despite their high economic potential as raw material for charcoal production. Purpose of the Study: This community service activity aimed to increase farmers’ knowledge of the economic value of coconut shell waste, build the capacity of business groups in entrepreneurship and financial management, and collect qualitative data as a foundation for a sustainable coconut shell charcoal enterprise. Methods: A qualitative case study approach was employed, integrating Participatory Rural Appraisal (PRA), Experiential Learning, and Project-Based Learning. A total of 16 respondents participated, selected through purposive sampling. Data were collected via structured interview guides and field observations, and analysed using thematic analysis. Results: The programme produced a three-fold increase in economic value per sack of coconut shells (from Rp 15,000–22,500 to Rp 65,400–65,574), and 87.5% of participants expressed readiness to join a collective business group. Five key qualitative findings were identified: a shift in waste perception, collective entrepreneurial readiness, identification of technology and capital needs, strong village government support (including potential BUMDes integration), and significant export and domestic market potential for charcoal products.

Abstract

PT Rivercape Indonesia has been failing to meet its annual production target of 23,000 units on Final Assembly Line F1, with actual output reaching only 20,667 units and an estimated revenue gap of USD 7,821,288.71. This study aims to identify the root cause of this shortfall, formulate improvement alternatives, and select the most appropriate alternative using an Assembly Line Balancing (ALB) approach supported by a Current Reality Tree (CRT) and the Analytic Hierarchy Process (AHP). The research method combined direct observation, focus group discussions, and internal company data collected from January to February 2026. The existing-condition analysis shows that the line operates with 26 workstations and a cycle time of 335 seconds, resulting in a Line Efficiency of only 74.39% and a Balance Delay of 25.61% (categorized as bad according to Yin, 2016). CRT analysis confirmed the root cause as the absence of a mechanism to optimize workstation utilization. Three improvement alternatives were evaluated against a target cycle time of 301 seconds: Alternative 1 (TSALBP Type 2) achieved a Line Efficiency of 82.79%; Alternative 2 (TSALBP Type 1) achieved the most substantial improvement, with a Line Efficiency of 93.90% across 23 workstations; and Alternative 3 (UALBP) achieved a Line Efficiency of 93.59% with a U-shaped layout. Using AHP with a Consistency Ratio of 0.011, Alternative 2 was selected as the most preferred strategy with the highest composite score of 0.500. Implementation of the selected alternative is projected to recover approximately USD 6.42 million of the existing revenue gap through a four-phase, nine-month implementation plan.

Abstract

Background: Project delays remain a major challenge in the construction industry due to their impact on project performance, revenue recognition, and contractual risks. This issue occurred in PT Ubinkayu Indonesia’s Project PRJ-155 in Surabaya, where actual progress reached only 44.24% compared with the planned 100%, resulting in a 55.76% schedule deviation. Objective: This study aims to identify the root causes of project delays, determine improvement priorities, and develop an integrated Project Control Framework to enhance project performance. Methods: A mixed-method case study was conducted using the Define–Measure–Analyze (DMA) approach from Lean Six Sigma, combined with Lean Construction principles. Quantitative analysis evaluated project performance indicators, including labor productivity, planning reliability, workflow stability, corrective activities, rework rate, and workforce utilization. Qualitative data were collected through observations, interviews, document reviews, and focus group discussions. A Current Reality Tree (CRT) was applied to analyze causal relationships, while the Analytic Hierarchy Process (AHP) was used to prioritize improvement alternatives. Results: The study identified the absence of a structured project control mechanism as the main cause of delays, leading to unstable workflows, shifting priorities, excessive workforce movement, corrective activities, and rework. Three improvement initiatives were proposed: Progress-Based Productivity Management, Installation Readiness Gate with Constraint Heatmap Planning, and Progressive Installation Inspection. AHP results showed that Installation Readiness Gate with Constraint Heatmap Planning was the highest-priority initiative. Conclusion: The proposed framework can improve planning reliability, labor productivity, workflow stability, and project completion efficiency while reducing corrective activities, rework, and financial risks associated with delays.
