Abstract

A slow and inefficient inbound process is a major challenge in the warehouse operations of PT DE, a company in the FMCG sector. This study aims to optimize the inbound process through the implementation of Lean Logistics. The method used is a quantitative approach by combining Lean Six Sigma through the DMAIC cycle and Kaizen principles through the PDCA cycle. Observations show that most inbound activities fall under Necessary Non-Value Added (NNVA), such as manual inspections, data entry, and documentation, accounting for up to 93% of the total process duration. Root cause analysis was carried out using Value Stream Mapping and Fishbone Diagram. Improvement solutions include implementing barcode/RFID technology, automated conveyors, employee training, and standardized procedures. After implementation, there was a significant increase in the speed and accuracy of goods receipt. Control was maintained through regular audits and a digital monitoring system. The application of Lean Logistics proved effective in reducing waste, increasing efficiency, and supporting continuous improvement in the FMCG warehouse environment

Abstract

This study aims to analyze the implementation of administrative theories in the management of education at SDN 4 Depok. The study responds to the challenges of applying educational administration practices in elementary schools that are often still traditional and formalistic, and have not fully adapted to modern administrative theories. Using a qualitative approach with a single case study method, the research explores planning, organizing, executing, and supervising activities in the school’s management, as well as supporting and inhibiting factors. The findings indicate that SDN 4 Depok has begun integrating modern administrative principles, such as participatory planning and initial use of technology, though the practices are still dominated by classical bureaucratic approaches with weaknesses in data-based evaluation, equitable task distribution, and systematic feedback. The study confirms that the school is in transition toward modern, collaborative, and data-oriented management. These findings are expected to contribute theoretically to the development of educational administration literature and practically as recommendations for improving the managerial capacity of elementary schools. Keywords: educational administration, classical theory, modern theory, school management, case study

Abstract

This study aims to determine the effect of implementing the Problem-Based Learning (PBL) model on student learning outcomes in the Ignition System competency at SMKN 1 Katapang. The background of this study stems from the low understanding of students regarding the ignition system material due to the dominant use of the Teacher-Centered Learning (TCL) model, which tends to make students passive and only memorize concepts without understanding the overall working process. PBL is considered more relevant because it emphasizes real problem-solving, critical thinking, collaboration, and analysis according to constructivist theory. The method used is a quasi-experiment with a Nonequivalent Control Group Design. The research subjects consist of two classes of 11th-grade Light Vehicle Engineering students: an experimental group using the PBL model and a control group using TCL, with a total population of 70 students. Data collection was done through pretests and posttests using a validated multiple-choice objective test instrument. Data analysis includes comparing the learning outcome improvements of both groups to determine the effectiveness of PBL. The results show a more significant improvement in learning outcomes in the class using the PBL model compared to the TCL class. This proves that the implementation of PBL is effective in improving analysis skills and diagnostic skills in the ignition system. Therefore, PBL is recommended as a more suitable teaching model for practice-based subjects in vocational schools, especially in automotive electrical competencies.

Abstract

Penelitian ini bertujuan untuk menganalisis postur kerja ergonomis serta keluhan musculoskeletal disorders (MSDs) pada mahasiswa dalam kegiatan praktikum di bengkel otomotif. Penelitian ini menggunakan metode kuantitatif dengan pendekatan deskriptif untuk memberikan gambaran objektif mengenai tingkat risiko ergonomi. Subjek penelitian adalah mahasiswa Pendidikan Teknik Otomotif yang aktif mengikuti kegiatan praktikum. Pengumpulan data dilakukan melalui observasi langsung menggunakan metode Rapid Upper Limb Assessment (RULA) dan Rapid Entire Body Assessment (REBA), serta penyebaran kuesioner Nordic Musculoskeletal Questionnaire (NMQ). Hasil penelitian menunjukkan bahwa sebagian besar aktivitas praktikum dilakukan dengan postur kerja yang tidak ergonomis, seperti membungkuk, menjangkau di luar jangkauan ideal, serta bekerja dalam posisi jongkok atau di bawah kendaraan. Analisis RULA menunjukkan bahwa 65% aktivitas berada pada kategori risiko tinggi hingga sangat tinggi, sedangkan hasil REBA menunjukkan 50% aktivitas berada pada tingkat risiko sedang hingga tinggi. Selain itu, hasil NMQ menunjukkan bahwa keluhan paling dominan terjadi pada punggung bawah (70%), leher (60%), dan bahu (55%). Temuan ini menunjukkan adanya hubungan antara postur kerja yang tidak ergonomis dengan munculnya keluhan MSDs. Oleh karena itu, diperlukan upaya perbaikan melalui edukasi ergonomi, perancangan ulang fasilitas praktikum, serta pengaturan aktivitas kerja yang lebih baik. Penelitian ini menegaskan pentingnya penerapan ergonomi sejak lingkungan pendidikan untuk mencegah risiko kesehatan jangka panjang dan meningkatkan efektivitas pembelajaran.

Abstract

Motorcycles are one of the main modes of transportation widely used by the Indonesian people due to their practicality, efficiency, and ability to support daily mobility. However, many motorcycle users complain about the suboptimal engine power, especially when the vehicle is used on extreme terrains outside urban areas, such as uphill roads, rocky paths, or long distances. This situation has driven the development of various innovations in the automotive field to improve engine performance. One widely applied method is the oversize technique on the piston and piston block, which aims to increase the combustion chamber capacity, thereby maximizing the power output. This study aims to analyze the significant comparison of engine performance after the application of the oversize method on the KVY engine type, as well as to examine the factors influencing the optimization of engine performance based on the philosophy and needs of the vehicle owner. The testing method used a dynamometer to measure the increase in torque and engine power. The test results showed that the daily oversize application resulted in a torque increase of 1.19 Nm and a power increase of 0.85 Hp compared to the standard condition. Meanwhile, the oversize for competition needs showed more significant improvements, with a torque increase of 7.97 Nm and a power increase of 8.12 Hp. These findings demonstrate that the oversize method can significantly enhance engine performance according to its intended use.
