Abstract

Kualitas hasil kerja dapat dipengaruhi oleh kondisi tempat kerja, metode kerja, dan kemampuan operator yang melaksanakan kerja tersebut. Penelitian ini dilakukan di sepuluh usaha percetakan yang berlokasi di Kota Medan. Penelitian bersifat deskriptif, observasi dilakukan terhadap aktivitas kerja pencetakan, kondisi kerja, jumlah produk cacat, penelusuran penyebab terjadinya cacat dan upaya untuk mereduksi jumlah cacat. Hasil penelitian menunjukkan sejumlah kriteria produk cacat pada kegiatan pencetakan dokumen, buku, koran, garment, sablon, dan undangan. Aktivitas kognitif yang utama pada operator pencetakan adalah eksekusi dan merupakan kegagalan fungsi kognitif yang memiliki persentase terbesar. Sebagian besar operator bekerja berdasarkan pengalaman, tanpa pelatihan yang memadai sehingga menimbulkan dampak terjadinya produk cacat. Upaya penanganan produk cacat yang direkomendasikan untuk masing-masing jenis produk dituangkan ke dalam 3 bagian prosedur yaitu pra operasi, saat operasi, dan pasca operasi. Tindakan penanganan produk cacat memerlukan kemampuan, ketelitian, dan kesiagaan operator dalam menjalankan tugasnya

Abstract

Excessive noise exposure during the manufacturing process is a widespread issue. This research aimed to analyze noise exposure in the kernel recovery station in the manufacturing process of palm oil. We conduct some measurements and calculations for noise exposure analysis to get the Equivalent Noise Level (Leq) value during the daytime for each measurement point. The noise measurement was conducted on four machines, including a depericarper and polishing drum machine, ripple mill machine, silo dryer machine, and clay bath machine. In addition, this research showed noise contour mapping to define the noise distribution.  The results of this research are that only the clay bath machine had Ls below the threshold. The clay bath machine workstation has good noise levels. The Depericarper, Polishing Drum, Ripple Mill, and Silo Dryer Machine must be quieter. Thus, this research used the Hierarchy of Control Approach to reduce and control hazardous noise exposure. The stage of HOC includes elimination, substitution, engineering, administrative control, and Personal Protective Equipment (PPE).

Abstract

The packaging station is one of the stations needed to produce the product. The workers in this station are still doing the process manually. The packaging station has several processes, namely the weighing process, the sewing process, and the moving process of the finished product by manually lofting the sack from the sewing machine to the pallet. The moving process has three activities holding, lifting, and moving. Workers who work manually often complain of pain felt while working, so they are at risk of experiencing musculoskeletal disorders. Accordingly, it is important to analyse the work posture to determine whether improvements must be made. The Rapid Entire Body Map (REBA) analyses the work position. Analysis of work posture is moving the product. The REBA method's posture assessment results are 8 for holding, 9 for lifting, and 10 for moving. From the results, it can be categorized as a high-risk level, and immediate improvements are needed. The improvements were made by designing a conveyor from the sewing machine to the pallet using the Anthropometric method with dimensions of 100cm, width of 65cm, and height of 113cm.
