Logistics costs have become a concern for the Indonesian government, and in 2024, they accounted for 14% of the Gross Domestic Product (GDP). Transportation costs are one of the elements of logistics costs. This condition has compelled leaders and teams in the apparel industry to allocate resources efficiently, effectively, and productively, with minimal waste. Based on this reason, the organization sought to identify the root causes of waste and implement improvements in transportation. These wastes of road transportation were identified and reduced by DMAIC (Define, Measure, Analyze, Improve, Control) method and lean tools, including Value Stream Map (VSM), Lean Metrics, Five Whys (5Ws), Transportation Overall Vehicle Effectiveness (TOVE) – Overall Equipment Effectiveness (OEE), transport software, and SmartSheet. Data collection and observations were conducted in 2024 and 2025, resulting in improvements across various aspects, including a 75.75% reduction in parking time, a 4.67% decrease in distance traveled, an 82.66% decrease in vehicle utilization, and a 16.66% reduction in transportation costs. The Lean concept remains an effective tool for reducing waste.

The manufacturing industry in Nigeria has been the so-called cornerstone of economic development since the sector has continuously played a major role in providing jobs and industrial capital. However, there remain issues that impede its progress, including inefficient resource use, unstable regulatory systems, and the need to comply with international market requirements. Specifically, it examined the effect of employee engagement, process efficiency, and resource allocation on Nigeria’s manufacturing sector. A survey research design was adopted, with a total population of 117 employees across five manufacturing firms. A total of 91 participants were administered a structured questionnaire. Data collected was analyzed using PLS-SEM. Findings revealed that employee engagement has the strongest effect on sustainable production (β = 0.412, t = 6.250, p < 0.000), followed by resource allocation (β = 0.237, t = 3.610, p < 0.000), and process efficiency (β = 0.174, t = 2.877, p = 0.004). It concluded that continuous improvement is significantly vital for sustainable production in the five sugar manufacturing firms studied in Nigeria. It is therefore recommended that management of these selected firms focus on developing unique resource allocation strategies, employee engagement, and process efficiency to ensure sustained workforce improvement, thereby achieving sustainable production outcomes.

Az utóbbi években egyre gyakoribbá vált a nagyszilárdságú acélok alkalmazása felrakóhegesztési eljárások során. Ennek egyik tipikus ipari példája az épületbontási munkálatokban használt hidraulikus ollók esete, ahol az alkatrészek nemcsak jelentős koptatóhatásnak, hanem intenzív dinamikus igénybevételnek is ki vannak téve. Az S690QL jelű, nemesített nagyszilárdságú acél alkalmazása e területen különösen elterjedt, elsősorban a felrakott réteg alapanyagaként, a bontóollók legnagyobb terhelésnek kitett zónáiban. A nemesített, nagy szilárdságú acélok azonban rendkívül érzékenyek a hegesztési hőciklus hatásaira, ami elsősorban a hőhatásövezet szövetszerkezetében és mechanikai tulajdonságaiban bekövetkező kedvezőtlen változások formájában jelentkezik. A felrakóhegesztés során érvényesülő hőciklusok jellegükben és lefolyásukban eltérnek a kötőhegesztésre jellemző paraméterektől, következésképpen a kialakuló hőhatásövezet szerkezeti és mechanikai tulajdonságai is különbözhetnek. Emellett a felrakott réteg beolvadási mélysége is változó lehet, amely lényegesen módosíthatja a nagyszilárdságú acél teherviselő keresztmetszetét, és ezáltal az alkatrész üzemi viselkedését. A kísérleti munka során S690QL alapanyagon végeztünk felrakóhegesztéseket különböző hőbevitel mellett, ezzel eltérő beolvadási mélységeket kialakítva. A vizsgálatok célja az volt, hogy meghatározzuk a beolvadási mélység hatását a felrakott alkatrész dinamikus igénybevétellel szembeni ellenállására. A méréseket +20 °C és -40 °C hőmérsékleteken is elvégeztük. Az eredmények egyértelműen igazolták, hogy a nagyobb beolvadási mélységgel rendelkező minták csökkent szívósságot mutatnak mindkét vizsgált hőmérsékleten. 

The purpose of this study is to investigate the factors that contribute to the success and resilience of construction projects in Ethiopia’s construction industry. A major gap exists in the current literature regarding the empirical validation of the relationships between resilience and success in the Ethiopian construction industry. Data collection was conducted via an online survey between March 8^th and May 13^th, 2024. PLS-SEM analysis was performed on the survey responses. Results indicate that resilience significantly impacts a project's success. The following are resilience-enabling factors that increase a project's resilience and enhance overall project performance. These are: resilient leadership (taking risks; learning from subordinates; being flexible during decision making); organisational structures (having few direct reports; narrow span of control; job rotation); and project team culture (assign right people for right jobs; recognition or rewarding the team members; team passions for contribution for project success; team trusts); external environment factors (mitigating high inflation effect; managing unstable economy; using appropriate legal enforcement); and risk management practices (communicating frequently; understanding/knowing how to implement risk management practices; integrating risk management practices into routine activities; having enough budget/finance). Success indicators for construction projects include quality, cost, time, safety and customer satisfaction. Therefore, developing resilience-enhancing strategies could greatly increase the effectiveness of construction project performance. The contribution of this study includes empirical evidence from the Ethiopian context, as well as practical recommendations for policymakers and project managers to create customised resilience strategies. The limitations of this study include reliance on self-reported data and convenience sampling in collecting survey responses. Overall, the study emphasizes the importance of resilience in overcoming the challenges of the construction industry in Ethiopia.

This study is expected to make a significant contribution to the advancement of the field.

The construction supervision consultant is an appointed party responsible for overseeing the implementation of construction projects from start to finish. The satisfaction level of project owners with the consultant’s performance is a key indicator of project success. This study aims to determine the level of satisfaction and key factors influencing it in public building projects. A quantitative method was employed by distributing questionnaires to respondents from the Public Works Office, particularly within the Cipta Karya Division in Tapin Regency, which serves as the case study location. Data were analyzed using the Customer Satisfaction Index (CSI) and Importance Performance Analysis (IPA) methods. The results showed that overall, the consultant’s performance was rated as very satisfactory, with the highest CSI score on the communication indicator (86.64%) and the ability to ensure and improve work quality (85.33%). The lowest CSI score was found in the documentation/administration indicator (80.11%). Although the CSI score indicates a high level of satisfaction, there is still room for improvement, particularly in administrative aspects and understanding of technical regulations. The IPA analysis also shows that several indicators fall under top priority, such as documentation/administration, supervision, internal human resources, communication, and the ability to ensure and enhance work quality. The improvement strategies proposed include training, high discipline, and effective communication.
