Abstract

The objective of this article is to review and represent about automation irrigations that have been gained in irrigation system performance evaluation for cultivation System of Rice Intensification (SRI) combined with Jajarlegowo System. This paper is based on the literature that is concerned with concepts, techniques, and methodologies applied to the automation irrigation and their performance in Indonesia. The development of automation irrigation for paddy field in Indonesia was presented and it was discussed. Several studies of automatic irrigation systems have been conducted in Indonesia. The results showed that the use of irrigation automation system combined with a system of rice intensification (SRI) and combined with jajarlegowo can increase rice productivity. This method is effective because the rice plants are watered according to their needs so that the growth becomes good. The method of irrigation automation is carried out using a water level control system adapted to the age of the rice plant. Water level sensors, irrigation actuators, and drainage actuators are installed in paddy fields to support the irrigation automation. In the application directly in the paddy fields owned by Indonesian farmers, this has not been done thoroughly. The main obstacle from the observation result of the research shows that automatic irrigation system technology has not shown any real difference compared to conventional irrigation. In addition, this automatic irrigation system should also be accompanied by human resources trained in its use and maintenance.

Abstract

Food processing with cooking needs a special way to keep the content of the nutrition of the food. This research aimed to test the temperature Frying of sweet potato chips in vacuum frying (vacuum pump type). Therefore, research had been conducted using factorial randomized block design with one factor, i.e., frying temperature (75 °C, 85 °C, and 95 °C). Parameters observed were loss of oil, water content, and organoleptic values. The results showed that temperature significantly affected the loss of oil, water content, and organoleptic value. The best result was found in the frying temperature of 95 °C.

Abstract

The incompatibility of construction of urban or residential drainage channels with design criteria is often found due to difficulties in designing drainage channels. designers often make design mistakes when designing drainage channels. This study aims to evaluate the drainage system and designs a drainage channel that can collect runoff discharge on Residential Area. The results of flood discharge obtained using the Gumbel method for the 10 and 25 year return periods are 298.78 mm and 370.38 mm. From the calculation of the channel capacity in the field and the discharge plan most of the existing channel capacity cannot accommodate the current planned discharge of 2.261 m3s-1 for the primary channel and 1.824 m3s-1 for the secondary channel. The current channel cannot accept runoff discharge during rain, so the channel rehabilitation plan is carried out by expanding and extracting the dimensions of the drainage channel.
