Abstract

As business competition intensifies, an organization needs to streamline operations and improve plant performance, focusing on minimizing waste. At Company XYZ, inefficient processes have led to persistent waste in crude palm oil (CPO) production, particularly in the forms of motion, waiting, and transportation. The objective of this study is to identify waste in the CPO production, analyze its root causes, and propose actionable improvements. A lean manufacturing approach was employed using Value Stream Mapping (VSM), Waste Assessment Model (WAM), Waste Assessment Questionnaire (WAQ), Value Stream Mapping Tools (VALSAT), and Cause-and-Effect Diagram methodologies. The VSM analysis revealed motion, waiting, and transportation as the primary waste categories. Waste identification using WAM ranked motion as the most significant waste (19.39%), followed by waiting (14.91%), transportation (14.57%), overproduction (14.23%), defects (14.21%), inventory (14.17%), and overprocessing (8.52%). Process Activity Mapping (PAM) identified 34 activities, with 50% being value-added, 9% non-value-added, and 41% necessary but non-value-added. This research improves operational performance and productivity in CPO production using lean tools. These interventions are expected to reduce waste and enhance operational performance significantly.

Abstract

Disasters may make people having to evacuate. When evacuating, evacuee may bring items required in evacuation place. The items must be ready previously in a bag, called a disaster preparedness bag. In case a disaster occurs, evacuee just grabs it and go for evacuation. Many bags used are not dedicated for disaster situation. Many types of items stored together and mixed causing of difficulty in retrieval. In addition, use of inappropriate bag will interfere with evacuee movement and slow down the evacuee while the evacuation time is too short. This research aims to design ergonomics disaster preparedness bag that can accommodate needs for 3x24 hours. Design process was started with planning phase to find out disaster preparedness bag development opportunity. The second phase is concept development. People who have evacuation experience are asked report their complaints regarding the bag used during previous evacuation and their needs for a disaster preparedness bag. Based on the needs, target specification is determined then concept alternatives are generated and selected. Then, main parts of the bag are identified. Continued with detailed design process, the dimensions of the proposed bag are determined using anthropometric data and dimension of required item in the first 72 hours of evacuation time. The design of proposed bag is such a backpack with multi compartments adjusted to item stored. The shoulder straps are designed like a vest then the load is not focused only on the shoulder but distributed to other part of body such as abdominal and chest muscle.

Abstract

Occupational safety is a critical concern in automotive workshop environments due to the high-risk nature of tasks such as engine repair, welding, and electrical diagnostics. This study investigates automotive workshop risks at the Mitsubishi DIPO Workshop in Bukittinggi by identifying hazards, assessing risk levels, and formulating workplace accident prevention strategies. The HIRARC (Hazard Identification, Risk Assessment, and Risk Control) method was applied to evaluate 28 potential hazards, two of which were classified as extreme risks. Further analysis of these risks was conducted using the Fishbone Diagram to identify root causes across six contributing factors: human, machine, material, method, environment, and management. Based on these findings, targeted risk control measures were developed following the hierarchy of control, including engineering interventions, administrative policies, and personal protective equipment. This research demonstrates how integrated methods such as HIRARC and Fishbone Diagram can support comprehensive occupational safety planning and risk mitigation in automotive workshops.

Abstract

Small and medium-scale food industries, despite their crucial role in regional economic development, face significant challenges related to hygiene, inefficiency, and process waste. This study, based on three case studies from IKM Kerupuk Janek Arsyila, IKM Kerupuk Buk Ita, and UMKM Kue Bawang Medan “Rizka” in West Sumatra, identifies key issues such as inefficient layouts, weather dependency, lack of standardized procedures, and low adherence to cleanliness standards. The study integrates Good Manufacturing Practices (GMP) for hygiene evaluation and Lean Manufacturing tools—such as Waste Assessment Model (WAM), Value Stream Mapping (VSM), VALSAT, and fishbone diagrams—to identify and reduce waste. Additionally, Information Technology (IT) is introduced as an enabler to strengthen monitoring, data collection, and documentation. Simple digital tools such as production dashboards, mobile-based hygiene checklists, and IoT-assisted sensors can facilitate real-time supervision and improve GMP compliance. Findings reveal that dominant wastes include transportation, motion, defects, and waiting, with initial Process Cycle Efficiency (PCE) ranging from 41% to 65%. After improvements involving layout redesign, drying machines, digital recordkeeping, and the 5S principles, PCE increased to 81%–95%. This study demonstrates that the integration of Lean–GMP and digital tools can significantly enhance production efficiency, hygiene standards, and sustainability in Indonesian food SMEs.

Abstract

Small and Medium Enterprises (SMEs) are the backbone of Indonesia's economy, contributing over 60% to the national GDP and employing more than 97% of the workforce. In Payakumbuh, culinary SMEs have significant potential due to the abundance of local raw materials and high demand for traditional foods such as rendang. Rendang Gadih is one such SME focusing on rendang production for both local and regional markets. However, inefficiencies in production, inconsistent quality, and manual management processes limit its competitiveness. This community service activity introduced the concept of Lean Manufacturing to improve efficiency and reduce waste. The main tools socialized were Value Stream Mapping (VSM), Process Activity Mapping (PAM), and identification of the eight types of waste, along with the application of Kaizen principles for continuous improvement. Implementation was carried out through preparation, socialization, and evaluation stages. The results of this activity are expected to help Randang Gadih enhance production efficiency, minimize waste, and strengthen competitiveness, serving as a model for other culinary SMEs in West Sumatra.

Abstract

XYZ SME is a small and medium enterprise (SME) based in Padang, West Sumatra, specializing in traditional skin crackers (locally known as kerupuk jangek a traditional cowhide-based cracker). The company faces critical challenges related to hygiene and production inefficiencies, particularly delays during drying and frying stages, as well as inefficient material flow due to a suboptimal facility layout. This study employs Lean Manufacturing tools to identify and reduce production waste. The methodology incorporates the Waste Assessment Model (WAM) to quantify waste types, Value Stream Mapping (VSM) to visualize the production process, and Value Stream Analysis Tools (VALSAT) to prioritize improvement strategies. WAM analysis identified transportation (21.277%), inventory (17.021%), and waiting time (14.894%) as the most significant waste categories. The initial Process Cycle Efficiency (PCE) was measured at 41.82%. Improvement proposals included enhanced GMP practices through training, supervision, and infrastructure upgrades, as well as production efficiency measures such as layout redesign, improved worker discipline, and the use of cost-effective machinery. These interventions led to a projected PCE of 95.24%, indicating substantial improvements in workflow efficiency.
