Abstract

Ginger is a horticultural plant that can be used as a spice or medicine. Slicing is the process of reducing the size by using a knife to get the length of the pieces that are smaller and thinner in a transverse, oblique or parallel direction to the material to be cut. The traditional slicing process is still relatively time consuming so it is not practical and cannot meet the needs. This study aims to design and performance test slicing machine type horizontal for red ginger and elephant ginger. The design is carried out on the hopper component and slicing system. The slicing performance test was carried out at rotational speeds of 46.67 rpm, 56 rpm and 65.33 rpm using 2 and 4 slicing blades with three replications. The results of the design show that the hopper using a clamping system can accommodate 13 kg of ginger. The testing results of the slicing system got the largest machine performance efficiency of 87.4% at rotational speed of 56 rpm with 2 blades with a slicing of 262 kg/hour. This slicing is very large compared to traditional slicing (3 kg/hour) and greater than previous studies with a slicing machine that uses a pressing mechanism (128 kg/hour).

Abstract

The performance of the irrigation network can be seen from several aspects such as the condition of the door and the suitability of the discharge coming out of the measuring instrument or door opening that is operated. This is used as information and input in the management of irrigation networks so that the distribution of water can be precise and even as well as a benchmark in evaluating water distribution. The performance of the tertiary irrigation network is measured based on six parameters. This parameter will determine whether or not there is an error in the management of the irrigation network. Good irrigation network performance will produce water discharge in accordance with irrigation water needs in each tertiary plot. The performance of the tertiary irrigation network on the Crump De Gruyter type has a very good performance. The level of efficiency of water use in the downstream area is higher than in the middle and upstream areas. Water distribution was 1.07 l/sec/ha during treatment, 0.82 l/sec/ha during plant growth and 0.4 l/sec/ha plant ripening.

Abstract

Hydroton is a clay-based growing medium used in hydroponic systems with variations in size 1-2.5 cm. In Indonesia, most hydrotons are still imported from other countries. The main purpose of this study was to observe the root growth and production of tomato plants grown on hydroponic systems, static aerated technique (SAT) with variations in hydroton size. This study was designed using a complete random design (CRD) with 4 hydroton size treatments (commercial hydroton as control (H0) and 3 experimental treatment with differences in hydroton size made from a mixture of clay and charcoal husk burn (H1, H2 and H3) and 6 replications in each size treatment so that there are 24 experimental units. On the observation of plant productivity showed different results on the treatment applied, while on the growth of roots did not show different results but the growth of roots on artificial hydroton better than commercial hydroton as a control based on physical roots and trend data. The amount of fruit harvested per plant obtained the best results of 25 fruits in the H3 treatment and the total weight of fruit per plant obtained the best results of 1.055,5 grams in the H3 treatment. The longest root in this study measured 96.6 cm in H0 treatment and the weight of the heaviest root in the net pot is 71,5 grams in H1 treatment while the weight of the heaviest root outside the net pot is 276,6 grams in H2 treatment. Based on the results of this study, the increase in the size of the hydroton is able to increase the production value of tomato plants compared to commercial hydroton and hydroton which are smaller in size.

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

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

Climate change is a change that occurs in the pattern of climate elements that are different from previous conditions. Climate change that occurs can lead to negative impacts on agriculture, namely the delay in starting planting time due to changeable weather not in accordance with forecasts until the problem of crop failure. East Lampung Regency is a regency that has the second largest agricultural land area in Lampung Province. Climate classification is the identification that is carried out to look for differences and determine the climate that occurs in a region. Climate identification can be done by monitoring changes in weather elements in a period of at least 10 years and at most 30 years. Oldeman's climate classification is to make climate types based on the number of wet months and dry months. The wet month category is the month that has rainfall >200mm and the dry month is with rainfall <100 mm. The purpose of this study was to determine the type of climate in East Lampung Regency based on oldeman climate classification, determine the right planting pattern for rice crops based on Oldeman climate classification, and determine the suitability of production and suitability of land for rice cultivation based on Oldeman climate classification. The method used in this study is the analysis of secondary data, namely rainfall for 10 years which is then interpolated with Geographic Information System applications. Based on the analysis results of East Lampung Regency has 6 types of climate, namely C1, C2, C3, D2, D3, and E3 with planting patterns applied in accordance with the oldeman climate classification. Suitability of land based on the type of climate obtained the results of 2 kinds of land types are very appropriate and marginal appropriate. While the suitability of rice production with climate classification East Lampung Regency has 13 districts that are appropriate and 4 districts are not appropriate. Sub-districts that are not suitable can be sought to have increased production results.
