Abstract

Surfactant is generally synthetic chemical, which is effective and reliable. However, the chemicals usually did not degraded easily in the environment and could cause damage to the environment. The other possible alternative to produce surfactant is using genetic engineering in order to produce peptide based surfactant. In this research, peptide surfactant was produced using a gene construct which was created using overlapped polymerase chain reaction method (OE-PCR). PAGE analysis shows that single surfactant peptide construction can be expressed by induction of IPTG 1 mM and after at least twice sonication. This research proves that both two constructions have been successfully expressed by producing peptide in expected size (approximately 15 kDa).

Abstract

The effleurage technique can increase blood circulation to the area being massaged. Increasing blood flow to the uterus and lower abdominal area can help in postpartum recovery and reduce the pain of uterine involution. This study aimed to determine the effect of effleurage massage techniques on reducing the scale of uterine involution pain in postpartum mothers on day 1 in the Cikadu Health Center Working Area, Cianjur Regency, Indonesia. This research is an experimental study with a one-group pretest-posttest design approach. It uses primary data obtained using an assessment instrument, the numeric rating scale (NRS), to determine the level of back pain in pregnant women. A total of 30 research subjects participated in this study. This study shows that effleurage massage intervention effectively reduces the intensity of uterine involution pain in postpartum mothers. There was a decrease in pain intensity after massage effleurage, and it was stated to be statistically different, p<0.05. In conclusion, there is an effect of the effleurage massage technique on reducing the scale of uterine involution pain in postpartum mothers on day 1 in the Cikadu Health Center Working Area, Cianjur Regency, Indonesia

Abstract

Petrochemical processes begin with relatively few basic raw materials, expand into a complex network of chemicals and converge into materials that serve specific functions as consumer products. Then raw material base for the petrochemical industry primarily depends upon the type of intermediates and final products required by industry and consumer. Almost all petrochemicals are derived from three sources: synthesis gas, olefin and aromatic. Production of those three petrochemical sources and the derivative chemicals are described briefly

Abstract

Gas bumi adalah suatu campuran gas hidrokarbon yang dipakai baik sebagai bahan bakar gasmaupun dapat dikonversi menjadi produk petrokimia, bahan bakar minyak sintetik dan bahan dasarpelumas sintetik. Pemakaian gas bumi untuk bahan bakar gas, bahan baku untuk industri petrokimia,bahan bakar minyak sintetik dan bahan dasar pelumas disajikan pada makalah ini.
