Abstract

Garlic was fried continually with vacuum frying equipment using temperature 85C and ratio of garlic to oil of 1/10 (w/v) for 15 hours. Frying time was 75 minutes for each with final yield of garlic chips was 0.35, final moisture content of 4.2%, and final oil content of 32.6%. Physical and chemical characteristics for oil and garlic chip deterioration based on alysin content showed that the alysin content of garlic chips was 1.99-2.65 times fresh garlic with decrease constant was 0.04 hour-1.  Free fatty acids formation was 0.0184% hour-1 with free fatty acids range 0.029-0.058%.  It was below standard value of free fatty acid i.e. 0.5%. Peroxide value formation was -0.11mek kg-1 hour-1 with peroxide value ranged 9.5514-10.6642 meq kg-1. It was also below standard value of 50 meq kg-1.  Carotene deterioration was 0.0184% hour-1 with its content ranged 0.029-0.058%, that still below standard value 0.5%.  Fatty acids formation was 0.0184 % hour-1 with carotene range between 6.05-11.44% per 100 gram. Frying oil lightness value ranged 46.6-48.5, redness value ranged 16.7-18.8, and yellowness value ranged 20.0-24.6. Lightness decreased with decreasing rate constant of 0.036 hour-1, redness 0.013 hour-1, and yellowness 0.17 hour-1. Garlic chip lightness value ranged 56.0-58.1, redness value ranged 20.9-27.5. and yellowness value ranged 29.9-32.1. Lightness of garlic chip decreased with rate constant of 0.017x2 + 0.218x, redness of 0.023x2 - 0.331x, yellowness of -0.083x2 + 1.2x. Correlation between peroxide deterioration of oil to garlic chips was 0.65, correlation between free fatty acid deterioration of oil to garlic chip was -0.78, correlation between lightness of oil to garlic chip was -0.75, correlation between redness of oil to garlic chip was -0.89, and correlation between yellowness of oil to garlic chip was -0.68. This result showed that oil life cycle was 150 hours.Keywords: vacuum frying, garlic chip, deterioration rate, carotene, alysin, correlation

Abstract

The watering of seedings can be done automatically by leveraging the development and advancement of technology, one of which is by utilizing a microcontroller that can be programmed to do watering according to the preferred time. This research aims to design and implement a scheduled fog irrigation system using the Arduino UNO microcontroller and utilizing the RTC (real-time clock) component in the mustard green seeding. In this research, the fog irrigation system is applied to green cabbage by optimizing the Arduino Uno microcontroller, which is used to design electronic circuits to automate the control of watering fog irrigation. Through this system, it is expected that plant watering can be done on time and the plant's water needs can be fulfilled. This research uses the experimental method or experiments with direct observation in the field through several stages, including preparing, designing, and making irrigation installations, constructing a series of scheduled fog irrigation systems, making scheduled irrigation program languages, calibrating RTCs, and working on scheduled fog irrigation systems. The research parameters include water use efficiency and the operation of the scheduled fog irrigation system. The observation parameters were water discharge (mL/min), water use efficiency (%), plant height (cm), number of leaves (strands), and performance of the scheduled fog irrigation system. Three treatments were applied in this study: first-time watering, second times watering, and third times watering. The scheduled fog irrigation system ran well during the research and aligned with the plan. In testing, the fog irrigation system has a water use efficiency of 75.86%, and in the treatment of fog irrigation, three times a day has the highest value of height and number of leaves with an average height of 3.72 cm and an average number of leaves 2.77 strands.
