Abstract

Test efforts to find alternatives to increase the even distribution of irrigation water on service land. The results of previous research conducted by researchers show that drip irrigation which is designed in stages with a water source from a drip irrigation tank using two types of emitters in a multi-stage drip irrigation system provides different irrigation water distribution results, so it is necessary to find a solution. so that irrigation can occur evenly. To get an alternative that might be tested is to use several types of emitters in the PVC pipe drip point holes, because these tools already exist on the market. This research aims to determine the effect of using two types of emitters, namely 2 lt/min and 4 lt/min emitters on distribution of irrigation water in a 4-tiered drip irrigation network. The test data analyzed includes irrigation distribution data, flow discharge data and irrigation uniformity (Cu), and the results of the analysis are presented in the form of tables and graphs and discussed before conclusions are drawn. The analysis results show that the average Cu for the two types of emitters is above 97%, which is very good and the two emitters have a very even distribution. The difference in distribution volume for each emitter, for a 2ml/min emitter is around 1ml -2 ml and for a 4 ml/min emitter it is 1ml -2 ml, with an irrigation network flow rate of around 84ml/min – 99.7 ml/min.

Abstract

Multilevel drip irrigation with PVC pipes is an efficient irrigation method that has the potential to be applied in urban settlements. Even though the land used is not very large, farming can be done effectively because it uses polybag land. This study aims to determine the effect of variations in PVC pipe drip irrigation networks with amiter on irrigation distribution, irrigation uniformity, and soil moisture levels with variations in irrigation duration. The test was carried out on four variations of tower water level and four variations of PVC drip irrigation networks in a multi-level system, with four variations of irrigation duration t1=5 minutes, t2=10 minutes, t3=15 minutes and t4=20 minutes. The test data analyzed includes irrigation distribution data and irrigation uniformity (Cu) and soil moisture recharge (Wt). The analysis results show that the best distribution of drip irrigation is obtained in network variation 3 with an average of 69 ml. The average uniformity obtained for Cu is above 97%, which is considered very good. Soil moisture Wt in variation 3 drip irrigation networks for a depth of 20 cm ranges from 0.69% - 21.65% at L1, at L2 around 2.16% - 21.65%, at L3 is 2.19% -21.68 % and at L4 it is 10.41% - 28.66%, so the higher the level position, the greater the soil moisture addition provided by irrigation.

Abstract

Mandalika Special Economic Zone is tourism area that is expected to improve the economy in West Nusa Tenggara Province. To support these activities, an allocation of domestic water needs of 200 liters second -1 is needed. The potential availability of water in the Pengga Reservoir is planned to be a source of domestic water needs in the Mandalika Special Economic Zone. Pengga Reservoir has an effective storage volume of 17.26 MCM. Potential water resources in Pengga Reservoir are obtained from reservoir outflow upstream and lateral inflow from several tributaries. The study was carried out to determine the reservoir storage capacity to meet domestic water needs and irrigation water needs covering an area 3189 ha. The cropping pattern used in the Pengga irrigation area is Paddy – Paddy/Secondary Crops – Paddy/Secondary Crops. To optimize the potential of water resources in the Pengga Reservoir, a linear programming optimization method is used. Indicators of the success of optimization calculations are indicated by the value of cropping intensity, k factor and reliability that have met the minimum limit value. The k factor value for irrigation water needs is 0.70 and domestic water needs is 0.85. Based on the optimization results, it is known the largest annual cropping intensity value occurs in the November I planting season. This conclusion can be seen from the comparison of annual cropping intensity values for the November I and November II planting schedules for the dry year inflow discharge scenario of 99.98% and 97.22% respectively. The cropping intensity value in the November I planting season is greater than November II, namely 100% and 97.25%, for the normal year discharge inflow scenario. This study provides an information for policy makers can use the November I planting schedule to obtain values for maximum cropping intensity and domestic water requirements.

Abstract

The use of multistage drip irrigation needs to be supported by adequate planting media so that irrigation water can be provided optimally. The planting medium used is practically soil mixed with compost and put in a polybag. Therefore, by adding compost with a certain composition to the soil, it is hoped that a good planting medium will be obtained. This test aims to determine the effect of using cocopeat compost and cow compost as well as soil as a planting medium in polybags on providing multistage drip irrigation. Flow characteristics on the distribution of irrigation water, its absorption capacity, absorption rate and irrigation uniformity achieved. The test was carried out on a ½” PVC drip irrigation network with a 2 lt/hour emitter consisting of 4 network levels on land measuring 2m x 4m, water source from a tower with a height of around 2.5m and a tank capacity of 150 liters. Test data for analysis consists of irrigation volume and distribution, drip system flow rate, irrigation uniformity (Cu), infiltration rate and irrigation depth. The analysis results show that the average irrigation distribution on floors 1 to 4 is 3028ml, 2937ml, 2848.25ml and 2793 ml, with flow rates on floors 1 to 4 of 40ml/s, 39 ml/s, 38 ml/s and 37 ml/sec. The amount of drip discharge (qt) on the 1st floor was 6.7ml/sec, on the 2nd floor the amount was 6.5 ml/sec, on the third floor it was 6.3 ml/sec and 6.2ml/sec on the 4th floor. Irrigation uniformity was obtained by 96% is considered very good, with an average infiltration rate hc in V2 of 0.04 cm/s, in V3 the hc was 0.03cm/s and in V4 the hc was 0.027cm/s. So the irrigation infiltration rate when using cocopeat tends to decrease if the portion of the planting medium increases, so its use needs to be limited.

Abstract

Soil moisture is the most important part of irrigation activities, because it is the result achieved by providing irrigation on a particular land. Likewise, with the application of drip irrigation, soil moisture is also the purpose of irrigation in the planting medium. In multilevel drip irrigation sistems, the potential for soil moisture produced by the irrigation sistem is very important to pay attention to, because the size of the moisture that can be provided will affect the scheduling of the drip irrigation provided. And therefore the ability of an irrigation sistem to provide optimum soil moisture in a particular medium deserves attention, before the sistem is applied to farming activities. For this reason, this test aims to determine the ability to provide soil moisture in a drip irrigation sistem that uses a 4 liter/hour emitter in a 4-tiered drip irrigation network, a polybag planting medium and an irrigation duration of 5 minutes to 20 minutes. The test data analyzed is irrigation and soil moisture distribution data, then the results of the analysis are presented in tabular form and discussed and conclusions are drawn. The test results show that the distribution of drip irrigation water occurs evenly with the optimal application of 41% moisture, and with the application of additional soil moisture of around 6% -7% for an irrigation duration of 20 minutes. The daily decrease in soil moisture that occurred during the three days of testing was found to be around 2% as a result of evaporation
