ANALISIS BEBAN KERJA FISIK DAN MENTAL MENGGUNAKAN METODE CARDIOVASCULAR LOAD (%CVL) DAN KONSUMSI ENERGI, SERTA NASA-TASK LOAD INDEX (TLX) (STUDI KASUS: PT BIMUDA KARYA TEKNIK)

Abstract

Abstrak

Penelitian ini dilakukan di PT Bimuda Karya Teknik (BKT), sebuah perusahaan manufaktur di bidang otomotif dan alat-alat berat. Studi ini menggunakan pendekatan multi-metode, yaitu pengukuran lingkungan fisik dengan 4 in 1 environment meter dan evaluasi beban kerja fisik dan mental melalui metode Cardiovascular Load (%CVL), analisis konsumsi energi, serta NASA-Task Load Index (NASA TLX). Pengukuran lingkungan fisik dilakukan pada tanggal 15 dan 16 Januari 2024 di lima mesin. (A3, A5, B1, B2, B4), dengan indikator kebisingan, pencahayaan, suhu, dan kelembapan. Hasil menunjukkan bahwa rata-rata kebisingan mencapai 91,243 dB, pencahayaan umum 130,284 lux, suhu lingkungan 33,849°C, dan kelembapan 63,091%, yang semuanya berada di luar nilai ambang batas (NAB) yang ditetapkan oleh Peraturan Menteri Tenaga Kerja Nomor 5 Tahun 2018. Beban kerja fisik dianalisis dengan %CVL, menunjukkan bahwa beberapa operator mengalami beban kerja fisik tinggi dengan CVL >30%. Konsumsi energi rata-rata operator melebihi 2,5 Kkal/menit, kecuali dua operator yang berada di antara 2 dan 2,5 Kkal/menit. Evaluasi beban kerja mental menggunakan NASA-TLX menunjukkan skor rata-rata 82,630, mengindikasikan beban kerja mental yang sangat tinggi. Berdasarkan hasil ini, direkomendasikan perbaikan kondisi kerja, termasuk peningkatan penerangan, pengaturan suhu dan ventilasi, serta pelatihan intensif bagi operator. Hasil penelitian ini memberikan rekomendasi perbaikan yang diharapkan dapat menjadi referensi bagi perusahaan dalam upaya meningkatkan produktivitas dan kesejahteraan karyawan.

Kata Kunci: beban kerja fisik, beban kerja mental, %CVL, lingkungan kerja, NASA-TLX.

Abstract

[Tittle: Analysis of Physical and Mental Workload Using Cardiovascular Load (%CVL) and Energy Consumption, as well as the NASA Task Load Index (TLX) (Case Study: PT Bimuda Karya Teknik)] This research was conducted at PT Bimuda Karya Teknik (BKT), a manufacturing company in the automotive and heavy equipment sectors. The study employs a multi-method approach, including the measurement of the physical environment using a 4 in 1 environment meter and the evaluation of physical and mental workloads through the Cardiovascular Load (%CVL) method, energy consumption analysis, and NASA-Task Load Index (NASA-TLX). The measurement of the physical environment was carried out on January 15 and 16, 2024, at five machines (A3, A5, B1, B2, B4), focusing on indicators such as noise, lighting, temperature, and humidity. Results show that the average noise level reached 91.243 dB, general lighting 130.284 lux, environmental temperature 33.849°C, and humidity 63.091%, all of which exceed the threshold values (NAB) set by the Minister of Manpower Regulation Number 5 of 2018. The physical workload was analyzed through %CVL, indicating that several operators experienced high physical workload with CVL >30%. The average energy consumption of operators exceeded 2.5 Kcal/min, except for two operators whose consumption ranged between 2 and 2.5 Kcal/min. The evaluation of mental workload using NASA-TLX showed an average score of 82.630, indicating a very high mental workload. Based on these results, recommendations for improving working conditions include enhancing lighting, regulating temperature and ventilation, and providing intensive training for operators. By implementing effective workload management strategies and improving the working environment, the company can enhance employee well-being and overall performance. The results of this study are expected to serve as a reference for other companies in efforts to improve productivity and employee well-being.
