Abstract

Aktivitas pengangkatan manual merupakan salah satu faktor yang berpotensi menimbulkan risiko ergonomis pada pekerja industri manufaktur, terutama jika dilakukan secara berulang dengan postur kerja yang tidak ergonomis. Penelitian ini bertujuan untuk menganalisis tingkat risiko ergonomis pada aktivitas pengangkatan Cable Box 800G di PT XYZ dengan menggunakan metode Nordic Body Map (NBM), Recommended Weight Limit (RWL), dan Lifting Index (LI). Pengumpulan data dilakukan melalui observasi, wawancara, serta pengukuran langsung terhadap dua operator yang melakukan pengangkatan tiga kardus Cable Box 800G dengan berat berbeda, yaitu 11,685 Kg dan 9,165 Kg. Hasil perhitungan menunjukkan bahwa aktivitas pengangkatan dengan berat 11,685 Kg memiliki nilai LI sebesar 3,748, yang berarti berisiko tinggi terhadap cedera muskuloskeletal. Sebaliknya, aktivitas dengan berat 9,165 Kg menghasilkan nilai LI 0,99, yang masih berada dalam batas aman. Hasil kuesioner NBM memperlihatkan bahwa keluhan paling dominan dialami pada bagian punggung bawah dan bahu, akibat posisi kerja membungkuk dan gerakan pengangkatan berulang. Kesimpulan dari penelitian ini adalah bahwa risiko ergonomis pada pekerja tidak hanya dipengaruhi oleh berat beban, tetapi juga oleh postur tubuh, frekuensi, dan cara kerja. Diperlukan penerapan prinsip ergonomi seperti perbaikan posisi kerja, modifikasi desain beban, dan penggunaan alat bantu angkat untuk menurunkan risiko cedera serta meningkatkan kenyamanan dan produktivitas pekerja.

Abstract

This research used blood cockle shells (Anadara granosa) originating from consumption waste in the Batam City area. Cockle shell samples were taken and prepared for analysis of mineral content using the FTIR method, including CaCO3 and other minerals. The blood cockle shells were applied to ultisol soil in Batam City to improve its fertility. The shells were crushed into a fine powder, then mixed with ultisol soil with several treatments, including 0 grams (control), 10 grams, 20 grams, and 30 grams with a soil mass composition of 220 grams for each treatment. The mixture of soil and shell powder was stirred until homogeneous before being applied to mustard greens plants. Based on the research results, the addition of shell powder had an effect on the level of plant fertility. The experimental results carried out showed an effect on each treatment given. This is in line with statistical testing with analysis of variance, obtaining a sig. value of 0.037 < α = 5% (0.05), indicating a significant difference in treatment for each treatment.

Abstract

The utilization of shell waste is often suboptimal, despite its potential as a composite filler material. This study aims to develop an environmentally friendly composite material based on gonggong shell powder combined with polypropylene. The research method involved the preparation of composite samples by mixing gonggong shell powder and polypropylene at various concentrations, followed by specimen fabrication using the hot press molding method. The resulting specimens were mechanically characterized through tensile testing based on the ASTM D638 standard, and the data were statistically analyzed using ANOVA to determine the significance of differences among composition variations. The research stages included observation, shell waste collection, cleaning, sterilization using NaOH solution, drying, grinding, and sieving to obtain fine powder. XRF analysis showed that gonggong shells are predominantly composed of calcium oxide (65.108%), indicating a high calcium carbonate content and strong potential as a composite filler. Tensile test results for specimens with polypropylene variations of 2.5%, 5%, 7.5%, and 10% revealed statistically significant differences (p < 0.05), with the optimal tensile strength of 35.03 MPa achieved at 5% concentration. These findings demonstrate that the developed composite material based on gonggong shell powder and polypropylene has strong potential as an environmentally friendly filler material with competitive mechanical properties.
