Abstract

Unpredictable weather changes often complicate the process of drying clothes, especially when sudden rainfall occurs. To address this issue, an automatic clothes drying system was designed based on the Arduino Uno microcontroller, utilizing a Light Dependent Resistor (LDR) sensor and a rain sensor. The LDR sensor detects sunlight intensity, while the rain sensor identifies the presence of rain. When sufficient sunlight is detected and no rain is present, the system activates a DC motor to automatically extend the clothesline. Conversely, if rain is detected or sunlight intensity decreases, the DC motor retracts the clothesline into a sheltered area. The objectives of this research are to (1) Protect clothes from getting wet due to sudden rainfall; (2) Optimize the drying process by utilizing sunlight intensity; (3) Reduce manual intervention in the drying process, providing convenience for users who are frequently away from home. System testing demonstrated that the device effectively responds to weather changes, thereby protecting clothes from rain and maximizing drying during sunny conditions. This system offers a practical solution for users concerned about the state of their laundry when they are not at home.

Abstract

Proses pembuatan totebag souvenir melibatkan beberapa tahapan yang menuntut efisiensi dan kenyamanan kerja operator. Dalam aktivitas menjahit, pekerja membutuhkan fasilitas kerja yang ergonomis seperti meja mesin jahit yang dirancang agar operator tidak perlu berpindah tempat berulang kali. Tujuannya adalah meningkatkan kecepatan, kenyamanan, serta menjaga kesehatan pekerja selama proses produksi. Penelitian ini menggabungkan metode Nordic Body Map (NBM) dan Rapid Upper Limb Assessment (RULA) untuk menganalisis keluhan otot dan postur kerja awal. Hasil survei NBM menunjukkan bahwa seluruh responden (100%) merasakan nyeri atau pegal di bahu kiri dan punggung, sementara 87% mengeluh pada lengan bawah kiri dan pergelangan tangan kiri. Berdasarkan analisis RULA, aktivitas menjahit dinilai memiliki tingkat risiko sedang dan memerlukan tindakan perbaikan dalam waktu dekat. Melalui metode Ergonomic Function Deployment (EFD) dan data antropometri, dilakukan perancangan ulang meja menjahit dengan prioritas utama mengurangi rasa pegal (skor 2,28), menambah kenyamanan (skor 2,19), serta mencegah cedera (skor 1,86). Hasil akhirnya berupa meja mesin jahit ergonomis berukuran 150 × 92 × 74 cm, dengan panjang mengikuti rentang tangan, lebar berdasarkan jangkauan tangan, serta tinggi disesuaikan dengan tinggi siku dan popliteal duduk.

Abstract

The digital transformation of academic administration services represents a critical requirement for enhancing the effectiveness and efficiency of higher education management. A primary challenge confronting the Industrial Engineering Study Program is the underutilization of the Work Practice (KP) and Final Project (TA) websites, compounded by the absence of standardized formats for administrative submissions, which continue to be processed via email. Such conditions contribute to processing delays, administrative errors, and an escalating workload for administrative staff. This community service initiative aims to advance the digital transformation of administrative services through the socialization of the KP and TA website and the standardization of administrative submission formats. The implementation employed an educational and participatory approach encompassing needs identification, material development, website socialization, and technical assistance, as well as monitoring and evaluation. The findings demonstrate a significant improvement in students’ and lecturers’ understanding of the KP and TA website, greater uniformity in administrative submission formats, and an enhanced potential for service efficiency. This initiative contributes to the optimal utilization of information systems and the cultivation of a digital literacy culture within the industrial engineering study program.

Abstract

Distribution is a critical component of logistics systems, especially in the food industry where perishable products such as frozen chicken require strict temperature control and timely delivery. CV XYZ, a frozen chicken distributor in Batam, encounters several operational challenges, including high transportation costs, limited cold chain infrastructure, and inefficient allocation of distribution routes. These issues not only increase operational expenses but also pose risks to product quality and delivery reliability. Therefore, an effective distribution strategy is required to ensure cost efficiency and service performance. This study aims to identify the most efficient transportation method to minimize distribution costs by applying three initial solution approaches: North West Corner Rule (NWCR), Least Cost (LC), and Vogel’s Approximation Method (VAM). The solutions obtained from each method were further evaluated using the Stepping Stone method to test their optimality. This research adopts a quantitative approach using a mathematical transportation model, with data collected through interviews and direct field observations. The results show that the VAM method produces the lowest initial distribution cost of Rp57,062,000, compared to Rp60,022,000 for the LC method and Rp63,916,000 for the NWCR method. After optimality testing, only the VAM solution remained unchanged, indicating that it had already reached optimality. Thus, VAM is recommended as the most effective method for optimizing frozen chicken distribution costs at CV XYZ Batam.

Abstract

This study presents the design and development of an optimized automatic flour dosing machine to improve dosing accuracy, operational usability, and repeatability for small and medium-sized bakery enterprises (SMEs). The research integrates product design and development principles with mechanical flow optimization to address the limitations of conventional manual and semi-automated dosing systems. A six-stage Engineering Design Process (EDP) was employed, encompassing user needs identification, quality function deployment (QFD)-based specification development, concept generation and selection using a Pugh matrix, prototype fabrication, and experimental validation. The proposed system integrates an HX711-coupled load cell sensor, an HC-SR04 ultrasonic proximity sensor, an Arduino Uno microcontroller, and an optimized funnel–gate dispensing mechanism to regulate powder flow. Performance was evaluated using a multi-setpoint approach (10 g, 30 g, and 50 g) with 30 independent trials per setpoint. Results demonstrate that the system achieved a mean absolute percentage error (MAPE) of 1.54%, 1.32%, and 1.83% at 10 g, 30 g, and 50 g setpoints, respectively, all below the 2% threshold and well within the 5% design specification. The coefficient of variation (CV) remained below 2.3% across all conditions, confirming stable repeatability. The modular, DfA-compliant architecture enhances manufacturability and maintainability while preserving cost-effectiveness for SME adoption. These findings indicate that dosing performance in SME-scale food production systems is influenced not only by electronic control accuracy but also by the optimization of mechanical flow behavior. The study contributes theoretically by demonstrating the role of mechanical dispensing design as a complementary determinant of dosing precision, while providing SME practitioners with a low-cost and maintainable automation framework suitable for resource-constrained production environments.
