Abstract

Limbah cair pabrik kelapa sawit mempunyai nilai COD yang tinggi. Penurunan COD yang tinggi dapat dilakukan dengan melakukan pengolahan secara anaerob yang akan dihasilkan biogas. Tujuan penelitian ini adalah untuk mengetahui seberapa besar degradasi COD dari limbah cair pabrik kelapa sawit dalam proses anaerob untuk menghasilkan metana. Penelitian ini dilakukan dengan digester 19 liter. limbah sebelum dimasukkan kedalam digester terlebih dahulu dilakukan pembenihan kemudian dimasukkan limbah cair kelapa sawit sebanyak 14 liter kedalam digester dan dilakukan analisis nilai COD, pH dan volume gas yang dihasilkan digester pada waktu 0, 6, 12, 18 dan 24 hari. Hasil penelitian menunjukkan penurunan COD pada hari ke 6, 12, 18 dan 24 berturut-turut sebesar 5090; 4099; 8015; 762 dan 1086mg/L yang diikuti dengan peningkatan akumulasi volume biogas sebesar 0.004, 0.009, 0.011 dan 0.012L, proses anaerob berlangsung selama 24 hari dengan nilai pH 4 – 6 sehingga disimpulkan bahwa nilai pH 6 pada digester mampu menghasilkan metana.

Abstract

Office work is one of the most common jobs in Indonesia. There are various health risks, especially if it is not in accordance with the worker's body position with tables and chairs. This study aims to evaluate the ergonomics of the office work environment that affect health. This research method by conducting field observations and interviews. Field observations by directly observing the object under study, while interviews were conducted by conducting direct questions and answers with workers. This study resulted in the comfort of chairs and work desks not being directly proportional to health. The highest health complaints occurred in the neck with a contribution of 22.73% followed by the back and hips with a contribution of 18.18% and 15.91%, respectively. In addition, as many as 50% of workers feel that their work performance has decreased due to available tables and chairs.
