Farming with drip irrigation systems on sloping dry land is very rarely found at the field level, so that many dry lands are rarely used by the community. To be able to support the application of drip irrigation on sloping land, it is necessary to test the effect of slope variations on the flow characteristics of the drip irrigation system. This study aims to determine the effect of variations in the slope of the transmission pipe, which describes the slope of the land, on the Reynolds number (Re) and the pipe friction coefficient (f) generated in the drip irrigation network. The test drip irrigation network was made of 4 PVC pipes with a distance of 80 cm between the pipes, the drip hole distance of 60 cm and a diameter of 0.5 mm. The test variations are the slope of the transmission pipe 10 °, 20 °, 30 °, 40 ° and the water depth above the outlet tower h1 = 20cm, h2 = 30cm and h3 = 40cm with various head heights. Research using a water source from a tower with a capacity of ± 200 liters with a height of 3.3 m, a transmission line of PVC pipe Ø1 / 2 inches long 3.35 m.The results showed that the Re value will be greater from drip pipe 1 to drip pipe 4. The range of Re values from 1 to pipe 4 is 195 to 992 which is classified as laminar. The amount of friction coefficient f obtained decreases from drip pipe 1 to drip pipe 4, with a value of 0.327 to 0.064.

Tomato farming in the dry land of Salut Village, North Lombok is very often done by farmers, because the plants are short-lived and the selling price of the harvest is quite stable. However, the development of tomato plants in this region is still constrained by the high demand for plant water (KAT), because there are not many references. For this reason, this study aims to determine the amount of water needed for tomato planting and other parameters for each growth phase (f). The study is conducted on a land measuring 7m x 28 m, the size of the beds around 0.75 m x 28 m, the source of water from a tank with a capacity of 1600m3 and drip irrigation for crop irrigation. KBT analysis used a formula (Caoli, 1967), with analysis data from field data when planting tomatoes, so the results of the study are expected to be more realistic to address these obstacles in the development of tomato plants in the district of North Lombok. KAT analysis results with the Caolli formula show, for once irrigation in the initial phase (f1) around 0.738 m3, the active vegetative phase (f2) around 1.667 m3 and the fertilization phase until maturation of the initial fruit (f3) around 3.087 m3. The amount of soil moisture (w) additional irrigation in each phase is for f1 around 4% -5%, f2 around 6.5% -12% and f3 around 12% -17%. The duration of drip irrigation by 40 minutes needs to be shortened in phase f1, for phase f2 the duration is sufficient, and in phase f3 the duration needs to be added by more than 40 minutes or the irrigation schedule is shortened to less than 4.

Peak discharge flood analysis is very crucial in waterworks design. The proper design flood discharge will produce effective construction dimensions as project requirement. Therefore, flood design calculations must be analyzed using appropriate methods. The problem in estimating design flood discharge is usually found in ungauged watersheds which do not have any water discharge measuring equipment.This study wants to test the flood design method using rain data input to be applied to the Babak River, so the result can be used as a guide in the selection of flood discharge calculation techniques in other ungauged watersheds.The accuracy test is carried out by comparing the results of these methods with the flood design resulted from a frequency analysis of the Annual Maximum Series. Based on the results of the calculation, the peak flood of the Harpers method has the smallest RE and RMSEP values are 8.960% and 88.546 respectively. Thus, it can be concluded that the calculation of the design of the flood peak Haspers method has the best accuracy of the analysis results when compared with the Melchior and Weduwen methods for Babak River.

Determining the rain pattern distribution is believed to affect the design flood. Providing hourly rainfall observations can be obtained, and the distribution patterns can be determined. However, in areas that do not have one, flood discharge calculations are carried out by distributing daily rainfall using empirical methods. This study distributes daily rainfall into hourly rainfall in the Jangkok watershed using ABM and Mononobe methods and calculates the flood hydrograph using the Nakayasu model. The synthetic unit hydrograph obtained from the actual rain distribution is then compared with the unit hydrograph generated from the empirical distribution, then the deviation is measured. The results showed that the Mononobe and ABM rain distribution gave the same hydrograph shape as the observation one, only for 2 hours of rain duration. As long as the rain lasts 3-6 hours, the peak flood discharge (Qp) tends to be lower, 7-20% for Mononobe and 2-7% for ABM. Then the Qp becomes overestimated (5-12%) for a rain duration of >6 hours. Mononobe gives the same flood peak time (Tp) as observation rain for 1-5 hours rain duration and becomes 1 hour earlier for >6 hours. In contrast, ABM produces peak times 1 hour longer than hydrographs with observation rain. Generally, the two methods provide a more significant hydrograph deviation for a longer duration of rain.

A phenomenon that often occurs in Indonesia which is also an annual disaster that hit several areas is drought. Drought is a condition in which an area, land, or community experiences a shortage of water so that it cannot meet their needs. Drought can be caused because an area does not experience rain or is dry for a long period of time or the rainfall is below normal, so that the water content in the soil is reduced or even non-existent. The areas to be analyzed are the Hidirasa watershed, the Rontu watershed, and the Jangka watershed in Bima Regency, West Nusa Tenggara. The analysis drought aims to determine the deficit, drought duration, drought criteria based on deficits and surpluses that occur by analogy to Oldeman's criteria, hydrological drought index analysis, and hydrological drought distribution maps. In this study, data were used for the Tawali watershed in the Hidirasa watershed, the Sari watershed for the Jangka and the Kumbe water for the Rontu watershed to determine the Q50 and Q80 thresholds using the method Flow Duration Curve (FDC) to obtain hydrological drought characteristics. In the analysis of hydrological drought in several watersheds in Bima Regency, the results show that the maximum deficit in the Hidirasa, Term and Rontu watersheds was 1.09 m³/s, 0.14 m³/s, 0.49 m³/s which occurred in 2001, 1995, and 2001. From the deficit, it was found that the average drought period occurred 8-9 months from May to December and even some until January which indicated that the drought criteria were in zone 2 according to Oldeman. The largest hydrological drought index is the Hidirasa watershed, the Jangka Watershed and the Rontu watershed, respectively, -0.45, -1.00, -1.00, with a very strong drought category.

Sumbawa Island is one of the largest islands in West Nusa Tenggara (NTB) Province with an area of 15,414.5 km². Climatic conditions greatly influence the economy of the people of Sumbawa Island because most of the population earns their living as farmers, planters and livestock breeders. Extreme climate changes often occur. This results in natural disasters such as floods, landslides and drought. Sumbawa Island itself often experiences floods in the rainy season and droughts in the dry season. Knowledge of climate characteristics will really help the people there, in overcoming and avoiding the impacts of extreme climate change now and in the future. This research functions to provide information regarding the climate characteristics of Sumbawa Island.The method used to analyze the climate characteristics of Sumbawa Island is the Thornthwaite and Schmidth-Fergusson climate classification methods. The data used is secondary data for 14 years (2005-2018). This data was obtained from the NT I River Basin Center and generation data using the Thomas-Fiering model for the next 10 years (2019-2028).The results of the analysis showed that according to Thornthwaite, Sumbawa Island in the 2005-2018 and 2019-2028 periods had the same climate type, namely a dry climate (E) based on an average PE index value < 16 and a tropical climate (A) based on an average TE index value. ≥ 128. According to Schmidth-Fergusson in the 2005-2018 and 2019-2028 periods, Sumbawa Island has the same 3 types of climate, namely a moderate climate (D) with a value of 0.6 ≤ Q < 1, a slightly dry climate (E) with a value of 1 ≤ Q < 1.67 and dry climate (F) with a value of 1.67 ≤ Q < 3.

Drought is a disaster frequently experienced in Pujut District, Central Lombok Regency. Almost every year, this area suffers from prolonged drought. This study was conducted to understand the characteristics of the droughts that occur, using a widely recognized drought assessment method as an effort to mitigate drought disasters in this region. The drought assessment used in this study is the Run method. This method was chosen due to its simplicity and the fact that it only requires rainfall data for its analysis. The results of the calculations for the depth and duration of the drought period are then compared with past droughts in the region and the natural phenomena that influenced them. The analysis using the Run method shows that the most severe and longest drought occurred at Pujut District from July 1997 to May 1998 (11 months) with a deficit of 800 mm from the average normal rainfall, and from 2014 to 2015 with a deficit of 553.54 mm. Both extreme droughts in 1997 and 2015 occurred in various regions of Indonesia and were related to the strong El Niño phenomenon occurred at that time

The aim of this study is to determine the discharge of rainwater runoff from different durations of rain, to determine the magnitude of the differences in the discharge of rainwater runoff produced, and to determine the differences in channel dimensions resulting from differences in the duration of rain used. This study uses 6 years of daily rainfall data recorded at Bengel Station, to calculate the planned flood discharge as an alternative for controlling rain runoff in the Green Asia Housing area with a land area of ±6 hectares, a test time was used with rain times selected as 24 hours and 5 hours. Flood discharge is calculated using the Rational formula with a rain return period of 2 years according to the design area. The results of data analysis will be presented in the form of tables, discussed and concluded descriptively.The results of the study show that there is indeed a quite large difference in flood discharge, where the use of a 24-hour rain period produces a planned discharge that is around 32% lower than the use of a 5-hour rain period. The dimensions of the channel produced for a discharge with a rain duration of 24 hours are also smaller than the dimensions produced by a flow discharge with a rain duration of 5 hours. The fact is that rain events with a duration of shorter than 24 hours are more common than rain events lasting a full day.
