Abstract

This study aimed to analyze the performance of drip irrigation systems, determine performance of tomato treated under the irrigation systems.Field research was conducted at the Laboratory of Land and Water Resources Engineering; and at the Laboratory ofintegrated field, Faculty of Agriculture, University of Lampung in August 2013 to December 2013.Irrigation systems consisted of main componens: water supplies, Polythilene lateral tube, and emitters. Emitter on every pot, were made of Polythilene (PE) fabric.Pot experiment consisted of 32 pots, divided into two groups, a group of 16 pots was treated with surface drip irrigation system and the other half was treated with subsurface drip irrigation system.  Variables observed to the irrigation systems wereflowrate, coefficient variance (CV), emition uniformity (EU).  Variables observed to the plant were evapotranspiration (ETc), Kc, Soil moisture, water consumption, plant growth, and yield.  The results showed that the surface drip irrigation system had flowrate of 0.96 liter/hour, CV of 0.41 and EU of 54.85%, while the subsurface drip irrigation system had flowrate of 1.08 liter/hour, CV of 0.41 and EU of 56.43%.  Plants performance treated with surface drip irrigation system showed total crop evapotranspiration (ETc) of 490,8 mm,  while subsurface drip irrigation system showed total crop evapotranspiration (ETc) of 580,9 mm.Higher crop evapotranspiration of subsurface drip irrigation system was due to better plant growth in the subsurface drip irrigation system.  This was also shown by higher crop coefficience (Kc) of subsurface drip irrigation system.Keywords : drip irrigation, tommato, evapotranspiration, surface, sub-surface

Abstract

PT Pos Indonesia is one of the state-owned companies in Indonesia engaged in postal and logistics services. Pos Indonesia launched a new innovation by creating the PosAja application which aims to facilitate customers in sending packages and letters. However, there are features of PosAja that need to be improved based on the results of reviews from users, including a lack of understanding of the features of the PosAja application, users find it difficult to track the position of goods and the delivery flow is not clear or the position of the goods is not mentioned. Therefore, it is necessary to evaluate the PosAja application so that it can be even better in its future services.  This research uses the UX Honeycomb method to improve user experience in a digital product or service. The system design uses the Unified Modeling Language and is implemented using the PHP programming language and MySQL database. The results of the user experience evaluation of the PosAja application with the UX Honeycomb method show that the average value of variables that can be accessed is 3.57, can be found by 3.93, can be used by 3.76, useful by 4.05, valuable by 3.95, desirable by 4.19, and credible. by 3.82 which means that the value is included in the good category. Desirable, useful and valuable variables have a high average value which indicates that this application is needed by users and the variable accessed has the lowest average which indicates that this application needs improvement and improvement in terms of access speed. The results of the above research can provide recommendations to PT. POS to increase access speed so that users find it easier to use the application even though it is through cellphone media with insufficient signal due to geographical factors of users.
