Analisis Risiko Hydrogen Recovery Unit (Hru) dan Prioritas Risiko Kegagalan Komponen Pipa Gas Hidrogen di PT Petrokimia

ABSTRACTHydrogen Recovery Unit (HRU) is a unit which serves to purify hydrogen gas and an advanced process of Pure Gas Recovery Unit (PGRU) which serves to separate of ammonia gas from the other gaseous in the process. HRU is a high potential of firesdue to the characteristics of hydrogen which is a highlyflammablegas. In 2006, there was an explosion onpipelinein AmmoniaPlantofPT PetrokimiaGresik.Thereforeweneedare-analysisoftheunitasapreventive measurementtoavoidsimilaraccidentsinthefuture.TheobjectiveofthisstudywastoanalyzetherisklevelofHRU in AmmoniaPlantarea.Thisresearchwasadescriptivestudywithanobservationalmethod.Datawereobtainedfrom interviews and observations.

The objective of this research was to study the growth and development pattern of under two year age children of mother with maternal goiter. The research design was retrospective cohort. The Study was conducted in Banyu Arang village, Ngoro Sub distric, Jombang Distric, because this village was categorized as severe endemic goiter area. The observed variables were iodine status of children, the growth parameters such as body weight gain, nutritional status, head circumference, chest circumference; the development parameters such as motor miles stone, and score of pre screening questionnaire for development (KPSP).The result of the study indicated that prevalence of maternal goiter was 48.21%, prevalence of iodine deficiency among under two years children was 8.93%. Median of urinary iodine excretion amongchildren of mother with maternal goiter was 404 μg/L and 506 μg/L for children of mother without maternal goiter. Mean of birth weight among children of mother with maternal goiter was 3.02 kg and 2.96 kg for children of mother without maternal goiter. The growth rate of children of mother with maternal goiter was 278.33 gram and 264.16 gram for children of mother without maternal goiter. The head circumference among children of mother with maternal goiter was 46.35 cm compared with 46.05 cm for children of mother without maternal goiter. Ratio of head circumference and chest circumference were 0.96 and 0.97 respectively, and indicated that no asymetric growth retardation among two groups. Despite no significant diference of total score of KPSP between children of mother with maternal goiter and without maternal goite, but there were 2 (two) children that detected under developed children because total score of KPSP less than 7, and they were found from mother with maternal goiter.It was concluded that there was no significant difference of growth pattern between children of mother with maternal goiter and without maternal goiter. It found that generally development of children of mother without goiter better than children of mother with maternal goiter.Key words: growth, development, IDD, maternal goite
