Abstract

Weir is one of the water buildings built across the river. Weirs are needed to elevate the river water level so that it meets the elevation of irrigation needs. In very diverse watershed conditions, it is very possible that a dam was built in a river channel that is not ideal because the river channel turns so that the building becomes less safe. To be able to know the safety of the weir from erosion that can cause the weir to collapse and break or overturn, it is necessary to conduct an experimental laboratory research on the position of the weir in the downstream of a river bend. Research related to its effect on sediment transport, especially in the formation of basic configurations needs to be known, because erosion at the bottom is the initial process of weakening the weir security. This research was conducted in the Hydraulics and Coastal Laboratory of FT. The irram in a river flume with a length of 8 m and a width of 50 cm. Weir test is carried out with 4 variations of discharge and 3 variations of the position of the weir downstream of the channel bends. Sedimentation data were analyzed by the methods of Mayer, Peter, Muler (M.P.M), Einstein and Shinohara-Tsubaki and topographic data analysis using the Surfer program. The results showed that in general the largest sediment transport occurred in the position of weir I at a distance of ½ channel width downstream of the center of the channel bends for all tests, with the magnitude of sediment transport occurring from the MPM method Qs = 1x10-4 m3 / dt / m, Einstein Qs = 6,371x10-6 m3 / sec / m, and Shinohara-Tsubaki Qs = 1,7951x10-4 m3 / sec / m. More dominant scouring occurs at the foot of the weir downstream, with the basic configuration formed in the form of antidunes and standing waves, and based on the Froude (Fr) flow rate including subcritical flow (Lower Flow Regime) with the basic configuration form of ripples and dunes

Abstract

      Many efforts have been made by various parties in overcoming the problem of waste and flooding, in residential areas that are starting to develop, one of which is by utilizing organic waste as a biopore filler to improve soil absorption and produce compost. The biopore infiltration hole technology can utilize organic waste to fill biopore media, which is used as a food source by biota in the soil layer. This study aims to determine the rate of biopore infiltration in the use of several types of organic waste such as (1) straw, (2) leaves and (3) household waste. Biopori is made from pipapvc 4 ”and 1 m in length with installation into the ground 80 cm and the rest above the soil surface 20 cm for testing purposes with a total of 12 test points and tested after 7 days to 21 days. For biopore holes without filler, the highest absorption rate was 85 cm / hour and the lowest was 42,167 cm / hour. The type of straw waste obtained infiltration rate of 179.34 cm / hour and the lowest infiltration rate of 86,770 cm / hour, with an average of 113.56 cm / hour. In the filler with leaf litter, the highest infiltration rate was 100,111 cm / hour and the lowest was 59,743 cm / hour, with an average value of 84.69 cm / hour. Whereas for household waste, the lowest absorption rate was 38 cm / hour and the highest was 100,111 cm / hour, and the average was 52,979 cm / hour. At the age of 7 days the waste has the highest absorption rate and after the waste is 21 days old it should be replaced with a new one.

Abstract

Climate and rain parameters are important factors that affect the availability of water resources on the earth's surface. The phenomenon of climate change that occurs today has an impact on the depth and distribution of rain and climatological parameters. The existence of rain and climate on Lombok Island changes very significantly every year. These changes affect various sectors, especially the irrigation sector. Thus, various adjustments must be made, such as adjusting the time of planting, cropping patterns and the types of plants being cultivated. In this case, knowledge about the characteristics of rain and climate that occurs on the island of Lombok is very important to know the pattern and magnitude of the incident as well as the time of the incident. This study was conducted to determine the condition of each climate variable in the Lombok island region by calculating the monthly average for 25 years. The smoothing uses the Theissen polygon method by utilizing 19 scattered rain station data and 4 climatological stations. Based on the analysis carried out, the results showed that the average monthly temperature ranged from 26.17-27.09°C, humidity 87.70-89.83%, sunlight 39.79-69.44%, and wind speed 53 ,73-110,21knot. The highest rainfall occurred in January of 235.33 mm, while the lowest occurred in August of 18.12 mm.

Abstract

This study aims to determine the effect of the use of 12 mm Netafim (NTF) pipe and ” pvc on a multilevel drip irrigation network, on the ability of irrigation uniformity and irrigation distribution on polybag land. The test was carried out on variations in tower water heights of 220 cm, 120 cm and 30 cm on the lateral drip pipe, data analysis was carried out on irrigation uniformity (CU), and the distribution of irrigation water volume at each network level. The research was conducted on a land area of 1.5 m x 4 m x 2 m, the distance between the irrigation level is 1 m and the tower height is 2.5 m. Based on the results of the analysis, irrigation uniformity was obtained about 95%, with a difference in irrigation volume between levels of about 2 ml – 3 ml in the combination of PVC and NTF, whereas if the drip pipe with NTF alone there was a difference in volume of about 20 ml. With the use of PVC with dripers on the 2nd and 3rd floors, and the use of NTF pipes on the 1st floor, it can improve the shortcomings of the multilevel irrigation system

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

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
