Abstract

Penelitian bertujuan untuk mempelajari pengaruh kondisi sosial ekonomi keluarga (X1) dan motivasi belajar (X2) terhadap hasil belajar siswa (Y) pada mata pelajaran Dasar-Dasar Kejuruan di SMKS Bina Satria Medan, khususnya siswa kelas X MP. Latar belakang penelitian menunjukkan bahwa hasil belajar siswa pada mata pelajaran dasar-dasar kejuruan masih rendah, dengan hanya 41,93% siswa yang mencapai Kriteria Ketuntasan Minimal (KKM) berdasarkan data ujian tengah semester ganjil tahun 2024/2025. Penelitian bertujuan untukmengetahui pengaruh kondisi sosial ekonomi keluarga (X1) dan motivasi belajar (X2) terhadap hasil belajar siswa (Y). Pendekatan yang digunakan adalah kuantitatif dengan metode ex-post facto. Populasi penelitian terdiri dari 83 siswa kelas X MP, dengan teknik pengambilan sampel total sampling. Hasil menunjukkan bahwa, variabel kondisi sosial ekonomi keluarga (X1) berpengaruh positif dan signifikan terhadap hasil belajar siswa, dengan nilai t hitung 2,380 dan signifikansi 0,020 (<0,05). Semakin baik kondisi sosial ekonomi keluarga, semakin tinggi hasil belajar siswa. Variabel motivasi belajar juga berpengaruh positif dan signifikan terhadap hasil belajar siswa, dengan nilai t-hitung 2,064 dan signifikansi 0,042 (<0,05). Motivasi belajar (X2) yang tinggi berkorelasi dengan hasil belajar yang lebih baik. Secara bersamaan, kondisi sosial ekonomi keluarga dan motivasi belajar berpengaruh signifikan terhadap hasil belajar siswa, dengan nilai F sebesar 18,488 dan signifikansi 0,000 (<0,05), yang berarti hipotesis diterima.

Abstract

Operational inefficiency is often caused by uneven workload distribution and unplanned job sequencing. Both factors lead to bottlenecks, prolonged waiting times, and ineffective resource utilization. This study investigates how workload optimization and sequencing decisions contribute to improving operating system efficiency. Using a descriptive literature study approach based on secondary data from sources on organizational behavior and operations management, the findings indicate that workload imbalance causes bottlenecks and declining workforce performance, while unstructured sequencing prolongs makespan and increases idle time. Priority rules such as Shortest Processing Time and Earliest Due Date can demonstrably shorten total completion time while improving resource utilization, whereas workload equalization has been shown to reduce operational disruptions. This study finds that addressing both variables simultaneously produces greater efficiency gains than handling them separately. Practitioners are advised to periodically assess workload distribution and apply sequencing methods suited to their respective production characteristics.

Abstract

Shallot trading businesses face persistent challenges in supply chain coordination, particularly regarding unstable agricultural yields, pest infestations, and volatile commodity prices, which demand a more structured information management system. This study aims to examine how the Enterprise Resource Planning (ERP) framework can strengthen supply chain operations at Gudang Bawang Jonpiter Silaen in Medan City. A qualitative case study design was adopted, with in-depth interviews conducted with the business owner as the primary data source, supplemented by academic literature. Findings reveal that the business operates through interconnected stages sourcing shallots from farmers, warehouse storage, product grading, and distribution to market traders where existing documentation practices already mirror the core logic of ERP. The study concludes that transitioning toward a fully integrated ERP-based platform holds significant potential for improving operational productivity, reducing data inconsistencies, and sustaining a well-coordinated distribution network. It is recommended that the business gradually adopt a digital recording system that integrates procurement, inventory control, and sales transactions into a unified platform.

Abstract

The Just-In-Time (JIT) system has long been a foundation of production efficiency in the global automotive manufacturing industry. However, the semiconductor crisis that struck the world in 2020 to 2023 presented a serious test of the resilience of this zero-buffer inventory-based production system. This study aims to analyze the resilience of the JIT system at PT Toyota Motor Manufacturing Indonesia (TMMIN) in facing supply chain disruptions caused by the global semiconductor shortage. Using a qualitative descriptive approach based on a single case study, this research utilizes secondary data from TMMIN Sustainability Reports 2022 and 2023, GAIKINDO production statistics, global industry reports, and verified academic literature. The results show that despite the semiconductor crisis impacting TMMIN production capacity, the company maintained operational continuity through three main adaptation strategies: production model prioritization, component stock optimization, and strengthened industry ecosystem coordination. These findings support the argument that JIT does not need to be abandoned, but rather evolved into an Adaptive-JIT model that integrates resilience mechanisms without sacrificing long-term Lean efficiency principles.

Abstract

Indonesia ranks second in global instant noodle consumption, reaching 14.26 billion servings in 2022, making product quality control a central concern for industry players. This study examines how Total Quality Management (TQM) principles are applied within Indonesia’s instant noodle industry and their relation to maintaining competitive advantage. A literature review method was used with a qualitative descriptive approach and content analysis of relevant academic sources. The study found that applying seven TQM elements, namely top management commitment, customer orientation, continuous improvement, employee involvement, production process control, supplier relationship management, and data-based decision making, contributes meaningfully to production efficiency, defect reduction, consumer trust, and global market competitiveness. This study offers a conceptual framework linking TQM, Quality Control, and Competitiveness specifically within the Indonesian instant noodle industry context, an area that has received relatively limited academic attention. Keywords: Total Quality Management (TQM), Quality Control, Industrial Competitiveness

Abstract

Penelitian ini bertujuan untuk menganalisis dampak kebijakan harga minyak goreng terhadap manajemen persediaan pada perusahaan produsen pangan, khususnya pada PT Indofood Sukses Makmur Tbk. Kasus kelangkaan minyak goreng yang terjadi di Indonesia pada tahun 2022 menjadi fenomena penting yang menunjukkan adanya ketidakseimbangan antara kebijakan harga, biaya produksi, serta sistem distribusi produk. Penelitian ini menggunakan pendekatan kualitatif dengan metode studi kasus melalui analisis literatur yang bersumber dari buku manajemen operasi, jurnal ilmiah, laporan penelitian, serta artikel berita yang relevan. Hasil analisis menunjukkan bahwa kebijakan harga eceran tertinggi (HET) minyak goreng memberikan pengaruh terhadap sistem pengendalian persediaan dan distribusi produk pada perusahaan produsen. Dalam kondisi tersebut, perusahaan perlu menyesuaikan strategi produksi, distribusi, serta tingkat persediaan agar tetap mampu menjaga kelancaran operasional dan memenuhi permintaan pasar. Selain itu, pengelolaan persediaan yang efektif, termasuk penerapan safety stock dan integrasi rantai pasok, menjadi faktor penting dalam menjaga stabilitas pasokan produk di pasar. Oleh karena itu, manajemen persediaan yang adaptif sangat diperlukan agar perusahaan mampu menghadapi perubahan kebijakan ekonomi serta dinamika pasar.
