Abstract

Penelitian dilakukan pada sungai Kahayan, khususnya daerah Kuala Kurun, Kabupaten Gunung Mas, Provinsi Kalimantan Tengah. Penelitian ini bertujuan untuk mengetahui kualitas air Sungai Kahayan berdasarkan data mutu air Sungai Kahayan oleh Dinas Lingkungan Hidup Provinsi Kalimantan Tengah. Analisis menggunakan metode Indeks Pencemaran, didapatkan data mutu air selama 5 tahun terakhir dan tren menujukan penurunan dari tahun 2018 – 2021, namun mengalami kenaikan pada tahun 2022. Dinas Lingkungan Hidup dalam penyelenggaraan perlindungan dan pengelolaan mutu air sungai Kahayan sudah melaksanakan upaya pemantauan, dan pengelolaan mutu air dengan cukup baik. Persepsi masyarakat terkait penggunaan air sungai Kahayan berdasarkan status mutu air menunjukan bahwa masyarakat daerah pesisir sungai Kahayan sudah beralih fungsi dalam penggunaan air sungai Kahayan menjadi lebih bijak. Dengan didapat hasil 0% untuk penggunaan air minum, dan masing-masing 5% untuk penggunaan mencuci baju, piring dan memasak. Namun masih menggunakan air sungai sebagai budidaya ikan air tawar dan peternakan sebesar 39% serta transportasi air sebesar 52%.

Abstract

Activities of coal mining at PT Mitra Barito Lumbung Energi's use a long-shift work system. Thus, can lead to a very high levels of risk exhaustion. Purpose of this study was to determine the effect of longshift on the work fatigue of HD Sany SKT80S operators by using the Work Fatigue Measurement Tool Questionnaire (KAUPK2). This study uses the relationship parameter between age and body mass index. The method used in this study is a statistical test method, namely the Chi-Square Test (Fisher's Exact Test), with data analysis using bivariate. The sampling technique used was judgment sampling with 14 respondents. The results showed that 8 out of 14 HD Sany SKT80S operators felt a relationship between work fatigue and the age factor, with symptoms of a sore right or left shoulder. The perception of fatigue is already above 50% that concluded that there are fatigue experienced by HD Sany SKT80S operators. Then, of the 20 dependent factors tested with two independent factors, the result is that the body mass index has no relationship with symptoms of work fatigue, but the age factor has a relationship with symptoms of work fatigue in its tested operators. Keywords : Longshift, the Work Fatigue Measurement Tool Questionnaire (KAUPK2), fatique
