Abstract

On the northeast coast of Sidoarjo Regency, East Java, most people carry out smoking business activities and have become a superior product for Sidoarjo Regency. The delicacy of smoked milkfish from the area which is the gateway to East Java Province is produced only from freshly caught fish. Fish are cultivated by paying attention to good water circulation so that they do not smell like the soil. Not only that, to produce savory smoked fish, fish must be processed traditionally, only with natural ingredients. The smoked fish craftsmen have fully memorized these conditions and guarded them for the continuity of their business. Smoked fish business centers in Sidoarjo are scattered in Sedati and Tanggulangin Districts. However, the largest is in Penatarsewu Village, Tanggulangin District. Processed fish is not limited to milkfish, but almost all types of fish caught in the sea and cultivated, such as tilapia, catfish and tuna. Different from the character of the village in general, almost every resident's house in Penatarsewu has a burning chimney. Some of the chimneys were made of iron, but others were constructed of red bricks mixed with sand and cement.

Abstract

Lemon peel is a waste containing essential oils which can be used as an aroma enhancer in food and drinks as well as aromatherapy. This study aims to determine the effect of microwave pretreatment power and time on the extraction of lemon peel essential oil. The research phase began with microwave pretreatment, namely lemon peel was put into the microwave with pretreatment times of 2 minutes, 4 minutes, 6 minutes, 8 minutes, and 10 minutes with microwave power of 100 W, 200 W, and 300 W followed by water-steam distillation 150 g of lemon peel. Furthermore, the distillate is put in a separatory funnel for ± 12 hours to separate the essential oil and water. The top layer is essential oil added ± 5 g of sodium sulfate (Na2SO4) to adsorb water. The best conditions for the extraction process of lemon peel essential oil was at 300 W microwave power and 2 minutes of pretreatment which produces clear yellowish lemon peel essential oil with a distinctive lemon smell with a yield of 4.88%, limonene content of 27.501%, and refractive index of 1.48.
