Pengembangan Model Evaluasi Kinerja Karyawan Terintegrasi Menggunakan Metode Analytical Hierarchy Process (AHP) Pada Industri Manufaktur Baja

2026-04-27T11:10:24SE Asia Daylight Time

In a rapidly expanding and increasingly competitive steel industry, organizations are required to implement integrated performance management systems that can effectively align human resources, operational processes, and strategic objectives. PT. Surya Mas Megah Steel Surabaya, as a steel manufacturing company with a complex production line, faces significant challenges in conducting objective evaluations of both employee and operational performance. The absence of a structured and measurable framework often leads to assessments that are not fully aligned with organizational goals.This study proposes the design of an integrated performance management system based on the Analytical Hierarchy Process (AHP), which functions as a multi-criteria decision-making tool to identify and prioritize Key Performance Indicators (KPIs). The pairwise comparison analysis reveals that work productivity (0.47) is the most dominant criterion, followed by work quality (0.28), work discipline (0.16), and team collaboration (0.10). The low Consistency Ratio value (CR = 0,021) indicates that the model is reliable, enabling it to provide a transparent and systematic evaluation tool for PT. Surya Mas Megah Steel to enhance performance assessment, improve efficiency, and sustain competitiveness in the steel industry.

Development And Performance Evaluation Of An Automated Spiral Potato Chip Processing Machine With A Capacity Of 12 Kg/H For Small-Scale Applications

2026-04-27T11:10:26SE Asia Daylight Time

This study aims to design, develop, and evaluate the performance of an automated spiral potato chip machine with a capacity of 12 kg/h for small-scale industrial applications. The developed system integrates a spiral cutting mechanism, a pulley–belt transmission system, and a structural frame to ensure stable and efficient operation. The research methodology includes CAD-based design, mechanical analysis, fabrication, and performance testing under rotational speed variations of 100–300 rpm. The experimental results indicate that the machine operates optimally within the range of 200–300 rpm, achieving a production capacity close to 12 kg/h while producing relatively uniform spiral cuts. Mechanical analysis shows that the transmission system and shaft are capable of effectively transmitting power without failure. In addition, finite element method (FEM) analysis demonstrates that the maximum stress and deformation in both the machine body and transmission system remain below the material safety limits, although some critical regions exhibit safety factors below the recommended value. Overall, the developed machine improves production efficiency and product consistency compared to conventional methods. This study highlights that the integration of mechanical design, experimental evaluation, and numerical analysis can produce a reliable system for small-scale food processing applications.

Development Of An Automated Sweet Martabak Machine For Small-Scale Food Production: Design And Performance Analysis

2026-04-27T11:10:27SE Asia Daylight Time

This study aims to design and develop an automated sweet martabak processing system with a production capacity of 25 kg/h. The proposed system integrates a mixing mechanism, heating unit, and electric motor into a single unit to improve production efficiency. The research methodology includes system design, mechanical analysis, fabrication, and performance testing. The results indicate that the system exhibits good mechanical performance, where the primary load is dominated by the dough with a moment of inertia of 0.27 kg·m², while the motor power of 362.9 W is sufficient to ensure stable operation. Performance evaluation shows that the system achieves a mixing efficiency of 85% and thermal uniformity of 80%. Compared to the conventional method, the automated system reduces processing time by approximately 50%, decreases labor requirements, and improves product consistency up to 90%. These findings demonstrate that the integration of mechanical and thermal processes significantly enhances production efficiency and product quality. The developed system has strong potential as an appropriate technology solution for small-scale food industries.

Penerapan Metode Seven Tools Dalam Menganalisis Kinerja Aktivitas Bongkar Muat Petikemas di PT XYZ

2026-04-27T11:10:29SE Asia Daylight Time

PT. XYZ mengalami masalah menurunya kinerja waktu kegiatan bongkar muat petikemas, yang dapat berdampak pada kualitas jasa layanan dan kepuasan pelanggan. PT. XYZ merupakan perusahaan yang bergerak dibidang logistik dengan kegiatan bongkar muat petikemas dan curah kering. Penelitian ini bertujuan untuk mengidentifikasi faktor-faktor penyebab turunnya kinerja aktivitas bongkar muat petikemas dan memberikan rekomendasi perbaikan untuk meningkatkan kinerja kegiatan bongkar muat petikemas menggunakan metode Seven Tools. Pendekatan pada penelitian ini berupa kuantitatif dengan observasi, wawancara dan dokumentasi. Hasil penelitian ditunjukkan pada diagram check sheet, histogram dan pareto bahwa faktor penyebab turunnya kinerja bongkar muat petikemas terdapat pada kejadian trouble sarana CC Ringan sebesar 69% dari semua kejadian. faktor lain ditunjukkan pada diagram fishbone yaitu pada kategori material, measurement, personnel, environment dan methods. Pada control chart juga terdapat beberapa sampel data yang berada pada luar batas kendala sehingga perlu dilakukan investigasi mendalam untuk melakukan perbaikan. Ditemukan korelasi negatif ada pada diagram scatter plot bahwa menurunnya jumlah throughput petikemas disebabkan oleh tingginya jumlah trouble. Beberapa rekomendasi perbaikan untuk meningkatkan kinerja aktivitas bongkar muat meliputi pemeriksaan rutin sebelum operasional, pemeliharaan, perbaikan fasilitas, revisi SOP dan pelatihan berkala untuk operator peralatan dan mekanik.

Implementasi Internet of Things (IoT) pada Sistem Otomasi Pencatatan dan Pengendalian Distribusi Air di PDAM Surabaya

2026-04-27T11:10:32SE Asia Daylight Time

Sistem pencatatan distribusi air pelanggan industri di PDAM Surabaya masih dilakukan secara manual sehingga berpotensi menimbulkan kesalahan, ketidakakuratan, dan kurangnya transparansi. Penelitian ini bertujuan merancang dan mengimplementasikan sistem otomasi berbasis Internet of Things (IoT) untuk meningkatkan akurasi, efisiensi, dan transparansi distribusi air. Sistem terdiri dari perangkat keras dan perangkat lunak. Perangkat keras menggunakan mikrokontroler ESP32 yang terintegrasi dengan RFID RC-522, keypad 4x4, sensor aliran YF-S201, dan solenoid valve. Data transaksi dikirim secara real-time ke server melalui WiFi. Perangkat lunak berupa website berbasis PHP dan MySQL yang menyediakan dashboard untuk admin dan pelanggan. Hasil pengujian menunjukkan seluruh komponen berfungsi dengan baik sesuai rancangan. Uji akurasi menunjukkan deviasi rata-rata ±10–50 mL pada kondisi aliran stabil hingga 1500 mL, masih dalam batas toleransi. Sistem ini mampu mengotomasi pencatatan, mengurangi kesalahan manual, serta meningkatkan transparansi dan pengelolaan data secara terpusat.
