Kesehatan dan Keselamatan Kerja (K3) penting untuk diperhatikan oleh setiap perusahaan. Pencegahan kecelakaan kerja dapat dilakukan dengan mengetahui risiko yang ada, salah satunya melalui metode Hazard Identification, Risk Assesment, and Risk Control (HIRARC). PT Cahaya Murni Andalas Permai (CMAP) merupakan perusahaan yang bergerak di bidang furniture dengan trademark Bigland Springbed. Analisis risiko dilaksanakan pada area produksi PT CMAP yang memiliki catatan 16 kecelakaan kerja pada tahun 2011–2014. Responden penelitian berjumlah sebanyak 45 orang pekerja area produksi dari 9 sub divisi dengan umur 20–45 tahun. Pengumpulan data dilakukan dengan penelusuran data sekunder, observasi, wawancara kepala produksi, dan kuesioner tenaga kerja. Data penelitian diuji validitasnya menggunakan Korelasi Pearson Product moment dan juga reliabilitasnya dengan Cronbach’s Alpha. Pada hasil penelitian didapatkan sebanyak 7 sub divisi berada pada level risiko low (78%) sedangkan 2 sub divisi lain yaitu pemotongan busa dan tahap finishing berada pada level risiko moderate (22%). Terdapat 4 faktor penyebab kecelakaan kerja yang dianalisis yaitu: sikap pekerja, material & peralatan, lingkungan kerja, dan tata cara kerja. Pengendalian risiko yang dapat dilakukan adalah dengan rekayasa/engineering, pengendalian administratif, dan penggunaan alat pelindung diri. Kata Kunci: Analisis risiko, kecelakaan kerja, HIRARC

This research aims to analyze the effect of seawater intrusion with measurement of TDS dug well water in Padang Utara Subdistrict. The measurements of TDS carried out in three villages in Padang Utara Subdistrict, namely the Village are Air Tawar Barat, Ulak Karang Selatan, and Ulak Karang Utara with twice sampling frequency: on November 2015 and February 2016. TDS concentration in November 2015 is in the range of 20 to 9000.8 mg / L, while the measurement of TDS concentration in February 2016 is in the range of 160.8 to 735.2 mg / L. Measurement of TDS in November 2015 showed that there were three wells that indicated to seawater intrusion, i.e. the ULS 8 (1101.6 mg / L), ULS 9 (9000.8 mg / L), and ULU 6 (1926.4 mg / L). Correlation between TDS concentration with coastline distance have a value r amounted to 0,118-.095. The results showed that there are some wells that indicated to seawater intrusion along the coast in Padang Utara Subdistrict.Keywords : distance, dug wells Padang Utara Subdistrict, , seawater intrusion, TDSAbstrak-Penelitian ini bertujuan untuk menganalisis pengaruh intrusi air laut dengan pengukuran TDS pada air sumur gali di Kecamatan Padang Utara. Pengukuran TDS dilakukan di tiga kelurahan di Kecamatan Padang Utara yaitu Kelurahan Air Tawar Barat, Ulak Karang Selatan, dan Ulak Karang Utara dengan frekuensi pengambilan sampel sebanyak dua kali yaitu pada bulan November 2015 dan Februari 2016. Konsentrasi TDS pada November 2015 berada dalam rentang 20-9000,8 mg/L, sedangkan pengukuran konsentrasi TDS pada Februari 2016 berada dalam rentang 160,8-735,2 mg/L. Pengukuran TDS pada ovember 2015 menunjukkan bahwa terdapat tiga sumur yang yang terindikasi mengalami intrusi air laut, yaitu ULS 8 (1101,6 mg/L), ULS 9 (9000,8 mg/L), dan ULU 6 (1926,4 mg/L). Hubungan antara jarak sumur dari bibir pantai terhadap nilai TDS memiliki koefisien korelasi sebesar 0,118 0,095, hal ini menunjukkan tidak adanya pengaruh antara jarak dengan nilai TDS. Hasil penelitian menunjukkan bahwa terdapat beberapa sumur yang terindikasi mengalami intrusi air laut di sepanjang pesisir di Kecamatan Padang Utara.Kata kunci : intrusi air laut, jarak, Kecamatan Padang Utara, sumur gali, TDS

This study aimed to analyze the effect of transportation on lead (Pb) concentration in fried street foods of Padang school area and to analyze hygiene and sanitation handling against processed fried street foods ingredients. Samplings for the analysis of Pb concentration in fried street foods of school was conducted at the school area that located on the primary arterial road and the local secondary road in Simpang Haru District. Fried street food sampling and vehicle volume counting were conducted for 7 consecutive school days. In addition, the distribution of questionnaires to students and also to all traders of street food. The average Pb content of fried street food on primary arterial roads in the range of 0.249 -0.288 ppm and on local secondary roads ranging from 0.155 -0.218 ppm. The content of Pb in the primary arterial road passes the quality standard set by National Agency of Drug and Food Control Indonesia (0.25 ppm) and SNI (0.2 ppm). While the Pb content of the schools in the local secondary road only passed the SNI quality standard. The levels of Pb in food and volume of vehicles passing through the primary arterial road has a correlation value of 0.714, while on local secondary roads was 0.143. Pb in foods was not only caused by motor vehicle pollutants but also treatment when handling. This can be seen from the number of street vendors who do a positive treatment on hygiene and food sanitation to fried street food only about 30 -70 %.

The purpose of this research was to analyze the effect of noise on the level of work-fatigue in the production area of three crumb rubber plants at Padang City, Indonesia. It also examines the impact of age, period work, marital status, and education level on work-fatigue. Occupational noise in the working area was measured using a Sound Level Meter, while work-fatigue was measured using the Indonesian fatigue measurement questionnaire (KAPUK2). The respondents of this study were workers in these plants, 213 people in the wet-area, and 135 people in the dry-area. Results showed that the average noise of the production area had exceeded the threshold value, which was 90.98 dB. There were 26.19% experienced mild-fatigue, 71.43% moderate-fatigue, and 2.38% heavy-fatigue. Noise, age, and working experience were a related and significant influence on work-fatigue, where the probability value was respectively 0.046, 0.001, and 0.000 (p≤ 0.05). The results of multiple regressions showed that occupational noise was the most influential factor in the occurrence of work-fatigue with an odds ratio of 3.92.
