This study aims to (1) Designing wake automatic watering equipment on dry land, (2) Determine the effective and efficient manner, (3) Knowing more specific performance in the use of electrical power. The benefits of this research (1) automated tool that can help overcome the shortage of water in the dry season in dry land, (2) helping farmers in overcoming problems crop irrigation in the dry season / dry, (3) scientific knowledge in automation watering drip irrigation system with pump solar energy as renewable energy. The research was conducted in the village of Batu Layar Sandik District of West Lombok in April 2011 to October 2011. This study uses an experimental method with the following steps: (a) Stage Design, (b) the assembly stage and followed by (c) Phase characterization automatic watering tool. At the stage of design executed by: measuring the ambient temperature (0C), measure wind speed (km / h), determine to what size of pump power (watts); followed by stages of assembly. Then proceed with step kerakterisasi automatic watering tool in the characterization of applying completely randomized design (CRD) factorial design composed 8 treatment. The first factor is the rotation of the motor pump with 4 variations of rotation, namely (1600, 1800, 2200 and 2400 rpm). Each treatment each repeated 3 times. While the provision of irrigation water treatment drops on each network is divided into blocks, namely (I, II, III and IV blocks) are taken based on the treatment of the above factors. Each treatment was observed parameters-parameters of chilli crop water requirements. The parameters characterizing automatic sprinklers include: efficiency of crop water requirements and water use efficiency in total. Results showed (1) automatic watering device can regulate the amount and uniformity of discharge of water droplets in every hole in the use of water for plants drip irrigation system with an average of (± 0.5632 liters /crop), the one-time watering at each plants with 2400 rpm motor pump. (2) System drip irrigation watering holes aimed directly at the plant, the amount of water used is very small. So that the area can be watered plants covering an area of ​​1.74 mx 2.09 m = 3.6366 m2 / plot. With a total land area is tested for this type of tomato plant and a land area of ​​39.78 ± m2 for the type of chilli plants, bringing the total land area of ​​± 68.21 m2 on the pump discharge position of  ±72.50578 liters/minute, and then flowed through 6 Fruit of the pipeline with the average number ±12.084297 liters perpipe on each plot. While in the pipeline, there are 16 pieces of water drain holes are directed at each plant to remove water in the respective holes per hole ± 0.755268542 liters/minute. (3) The electric power is used to drive the pump motor in this study is similar to the output ±0.336796 HP the uotput equal to ±0.336796 HP x 0.7457 kWatt = 251.25 watts, where as the unused power of ± 1.333333 watts with efisiensin power to the pump motor power calculation is divided power is used together with efficiency = 251.25 watts/1.333333 watts x 100% = 18843.75%.

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

AbstractControl of soil moisture can save water supply for crops. The soil moisture sensor integrated with the Arduino microcontroller board can be programmed as the control system. Addition of RTC module and SD module tools also make the system as the data logger. The purpose of this research was to developed the irrigation automation system with the control of soil moisture. This system has been integrated with the automation system using the power source of solar energy. Soil texture is sandy clay loam, which is dominated by the sand content of 59.67%. Rainfall during the study was 58.5 mm. The control system with Arduino board, set to keep soil moisture between 0.23 cm3cm-3 - 0.30 cm3cm-3. The soil moisture in that range was able to be controlled with this system. Land without agricultural cultivation activities when water resources are limited, can be empowered with the application of irrigation automation systems.AbstrakPengendalian kelembaban tanah dapat menghemat pasokan air untuk tanaman.
