Abstract

Gadingrejo District is one of the sub-districts that often experience of flooding. Based on the Central Statistics Agency in 2020, Gadingrejo Sub-district is the only sub-district that floods 7 times in one year. One thing that can be done is the construction or repair of channels/rivers to dispose of floods by taking into account the design fof lood discharge. This study aims to determine the intensity and maximum design flood discharge at the 2, 5, 10, 25, and 50 year return periods in the Way Tebu watershed, Gadingrejo District, determine and the channel capacity of the Way Tebu river, and determine whether the capacity of the Way Tebu river in Gadingrejo District can accommodate design flooding at 2, 5, 10, 25, and 50 year return periods. This research method uses the rational method to determine the design flood discharge and the continuity equation to dbydischarge capacity. The results of the analysis show that theof value of the flow coefficient in 2011 was 0.233 while in 2019 it was 0.257. From these results, it is known that there are land function experts with an increase in the flow coefficient of 0.024. Rain intensity and maximum design flood discharge in the Way Tebu watershed in the 2-year return period is 4,403 mm/hour with a discharge of 39,577 m³/s, the 5-year return period is 5,914 mm/hour with a discharge of 53,164 m³/s, and the 10-year return period is 6,489 mm/hour with a discharge of 58,333 m/s, a 25-year return period of 6.918 mm/hour with a discharge of 62,185 m/s, and a 50-year return period of 7,102 mm/hour with a discharge of 63,837 m³/s. These results are in accordance with the literature which states that the design flood discharge is directly proportional to the intensity of the rain, where if the intensity of the rain that occurs is low, the resulting discharge will be small. Vice versa, if the intensity is high, the resulting discharge will be high. The discharge capacity of the Way Tebu canal/river in Gadingrejo District is 43,146 m³/sec. The capacity of the Way Tebu river can only accommodate design flood discharges during the 2-year return period. However, at the 5 to 50 year return period the capacity of the Way Tebu canal/river can no longer accommodate the design flood discharge. To prevent and reduce the flood discharge, it is necessary to hold river normalization and water conservation programs as often as possible, such as river deepening or sediment cleaning/dredging.

Abstract

This study aims to determine the effect of aggregate hydroponic growing media and EC (Electrical Conductivity) nutrient solution on the growth and production of melon (Cucumis melo L.). This study used a Factorial Completely Randomized Design (RALF) consisting of 2 factors, namely the type of planting medium (cocopeat and husk charcoal) and the EC value (1, 2, 3, 4, 5) mS/cm, each replicated as much as 3 times to obtain 30 experimental units. The results showed that cocopeat was a planting medium that gave the best response to the parameters of fruit weight and sweetness level with an average fruit weight of 2.46 kg, in addition the use of EC 2 mS/cm and EC 3 mS/cm gave the best response to parameters of fruit weight and sweetness level with an average fruit weight of 2.04 kg and 2.05 kg. Based on these results, the use of EC 2 ms/cm was chosen as the best treatment, because it gives maximum results by spending less resources when compared to EC 3 mS/cm.

Abstract

Palas District is one of the districts with the largest rice field area in South Lampung which has 5.589 hectares of rice fields. With such a large rice field area, Palas District in 2020 recorded a rice production figure of around 53,458 tons with a productivity of 58.84 quintals/hectare. This number could increase if there were no rice fields that failed to harvest due to the flood disaster. In 2017 around 345 ha of rice plantations in six villages, Palas sub-district experienced flooding. The flood event was repeated again in 2019, where 200 hectares of paddy fields were flooded. In the latest incident in February 2021, as many as 298 hectares of rice plantations spread across 7 villages, Palas District, experienced a loss due to flooding. In terms of mitigation, mapping of disaster vulnerability and disaster risk can utilize remote sensing and geography information system (GIS) technology. This study uses overlay and scoring methods with six flood variables, namely rainfall, soil type, land use, land slope, land elevation, river density. The mapping carried out will be validated with actual field conditions. The results showed that 77% (3840.45 Ha) of paddy fields were in the "Very vulnerable" category, 22% (1117.14 Ha) were in the "Vulnerable" category, the "Quite vulnerable" category was 0.068% (3.63 Ha), and the “Not Vulnerable” is 0.0002% (0.0012 Ha).

Abstract

The impact of drought can affect various aspects of life. One that is threatened by the effects of drought is agricultural land and rice fields, which are threatened with failure due to reduced water supply. South Lampung Regency is one of the largest rice producing districts in Lampung Province, with rice fields covering an area of 38,688 ha, South Lampung Regency is capable of producing 321,822 tons of rice. While Candipuro District is the largest producing district in South Lampung Regency with a total rice production of 55,192 tons of rice. From the magnitude of the potential Candipuro District has drought constraints in utilizing the potential of paddy fields optimally. One of the efforts that can be done to anticipate drought is by mapping the rice fields in Candipuro district which is prone to drought. One of the technologies that can be used in mapping is application-shaped technology called GIS (Geographic Information System) Application. The purpose of research on the level of drought based on Geographic Information System in Candipuro District is (1) to obtain a map of the distribution of drought-prone rice fields in Candipuro District, (2) to determine the level of drought-prone rice fields in Candipuro District, (3) to analyze the dominant factors that affect the level of drought-prone rice fields in Candipuro District. The method used in this study is the method of overlap (overlay) and scoring (scoring) with GIS analysts. Overlay and scoring methods were performed on 5 drought parameters, namely rice field irrigation, slope slope, soil texture, soil solum and rainfall. The results of research on rice field drought in Candipuro district obtained two levels of drought prone, namely, medium and high. Paddy land with a classification of medium vulnerability level has an area of 4,050.43 or comparable to 61.8% of the total area of paddy land in Candipuro district, while the classification of high vulnerability level has an area of 2,503. 3 ha or comparable to 38.2% of the total area of paddy land in Candipuro District. Keywords: Drought, Paddy Field, Candipuro District, Geographic Information System

Abstract

Making sweet chicken eggs using a sugar solution takes 5 days. This study aims to study the effect of the concentration of the sugar solution and the immersion temperature level on the sugar content in broiler eggs after soaking. This study was designed using a Factorial Completely Randomized Design (CRD) consisting of 2 factors, namely the concentration of sugar solution (15%, 20%, and 25%) and temperature (40 oC, 50 oC, 60 oC, and 70 oC) respectively. Based on this research, each treatment was soaked for 120 hours and repeated three times. The results of this study indicate that the concentration and temperature of immersion affect the sugar content and organoleptic content of sweet chicken eggs. The higher the concentration given, the higher the total sugar content produced in sweet chicken eggs and the higher the immersion temperature, the faster the diffusion of sugar into the eggs. Keywods: diffusion, sugar concentration, Sweet egg, temperature.
