Material handling is a term for transportation or transport activities carried out by industrial companies, which involve moving raw materials, semi-finished goods or finished goods from one location to another predetermined location. Apart from that, material handling is also important in quality control, where 3-5% of damaged goods are caused by material handling. The aim of this research is to identify and redesign the layout conditions of concrete production facilities at PT. XYZ. The method of this research is the Activity Relationship Chart (ARC), Activity Relationship Daigram (ARD) and Total Closeness Rating (TCR) methods. In the current layout conditions, the sand warehouse and crushed stone warehouse work stations should be close to the two hoppers, namely the batching plant hopper and the asphalt mixing plant hopper, but in the actual conditions these two work stations are not close to each other. In the new facility layout there are changes and relocation of work stations based on the degree of proximity. Future research is expected to consider the amount of time generated during the material handling process and also consider cost aspects during the process of designing changes to the facility layout.

This project is motivated by the high risk of work accidents in the concrete production process, especially at night when there is poor lighting. Based on observations, there were various significant work incidents, such as injuries from sharp objects and being caught in heavy equipment, which indicate the need for increased risk control. This study aims to design personal protective equipment in the form of an innovative safety helmet using the Job Safety Analysis (JSA) method to improve occupational safety and health (K3) at PT Adhi Persada Beton Batching Plant Kebonarum. The methodology used includes hazard identification, risk analysis, and solution development in the form of designing a safety helmet that is adjusted to the ergonomic needs of workers. This study also includes analysis of work accident data, identification of potential hazards, and evaluation of the effectiveness of existing personal protective equipment. The results of the study indicate that the application of the JSA method can identify risks in a more structured manner, as well as produce recommendations for safety helmet innovations that can improve worker protection against potential hazards.

Produktivitas Batching Plant merupakan faktor kunci dalam menentukan efisiensi dan keberhasilan proyek konstruksi. Penelitian ini dilakukan untuk menganalisis produktivitas Batching Plant di PT. Merak Jaya Beton, dengan fokus pada Batching Plant KarangPilang, selama bulan September dan Oktober 2023. Metode penelitian melibatkan pengumpulan data primer melalui observasi dan wawancara langsung di lapangan, serta pengumpulan data sekunder dari informasi perusahaan. Produktivitas Batching Plant diukur dengan menggunakan rumus produktivitas berdasarkan volume beton yang diproduksi dalam suatu periode waktu. Hasil analisis menunjukkan bahwa produktivitas Batching Plant KarangPilang mencapai rata-rata sekitar 26 m³/jam selama kedua bulan tersebut. Meskipun berada di bawah batas maksimum harian yang dapat dicapai, yaitu 60 m³/jam, produktivitas tersebut masih mencapai sekitar 44,08% dan 43,53% dari batas maksimum pada bulan September dan Oktober, berturut-turut. Faktor-faktor yang memengaruhi fluktuasi nilai produktivitas harian melibatkan penyesuaian jadwal pengiriman berdasarkan permintaan dari pihak proyek. Penelitian ini memberikan wawasan bagi PT. Merak Jaya Beton untuk meningkatkan efisiensi dan kinerja operasional Batching Plant KarangPilang dalam upaya menjaga kompetitivitasnya di pasar konstruksi.
