Abstract

Fruit chips are the result of the processing of horticultural produce that does not use high temperatures. The abundance of agricultural products in Indonesia and still not many agricultural product processing technology make the fruit frying business a good prospect. On the one hand, processing fruit chips with hight water content characteristics require a special frying technology called low temperature and pressure. On the other hand, this equipment is still not widely developed or even owned by small and medium enterprises. Therefore, this study aims to design and test a vacuum fryer for salacca. The vacuum method used is to use a vacuum pump recycled from the vacuum part of the cooling unit. The parameters observed were the effective capacity of the equipment, water content, and organoleptic test. The research results showed that the equipment's effective capacity was 0.26 kg/hr with 1.63% (w.b.) water content.

Abstract

Discharge rating curve is a curve that shows the relationship between water level and river flow so that it can be used to predict the amount of discharge in the river. The purpose of this research was to find the equation of the discharge rating curve in the Deli watershed. This research was carried out by analyzing river water discharge and taking water level data using a water level logger with a minimum of twice a week. River water discharge at the study location has a varied value i.e 0,74 – 3,28 m3/sec with an average of 1,06 m3/sec. The determination of the equation of the discharge rating curve uses several methods namely linear, polynomial, power function, logarithmic, and exponential. The results of the study show that the equation with the second order polynomial method has the best level of correlation (r) and RMSE with value r 0.986 and RMSE 0.011. The rating curve equation obtained was Q = 18,97 (h)2 – 1,372(h) + 0.190.
