Abstract

Evaluation of information system performance is needed to get an overview of the ease of end-users in utilizing a new technology. This study aims to evaluate the performance of information systems in a state-owned company (PT PLN Madya Langsa) based on an end-user perspective that is separated into two categories: employees and managers. The level of employee satisfaction (primary user) is measured using EUCS (aspect of: content, accuracy, format, ease of use, timeliness, and satisfaction). The manager's satisfaction level (secondary user) is measured by using IT BSC (aspect of: company contribution, user, operational excellence, and future orientation). The evaluation on the primary user showed that it was low at 25.6%, moderate at 56.64% and high at 18%. The percentage of user satisfaction with the information systems is 72.9% of the results expected by users. Meanwhile, evaluation on the secondary user obtained the following results: low at 10.5%, moderate 84.2% and high at 5.3%. The percentage of user satisfaction with the information system was 92.8% of the results that is expected by users. This study also discusses why there are differences in the percentage of primary user satisfaction compare to the secondary user and provides suggestions how to improve the level of satisfaction of the end users in the future.

Abstract

Water environmental factors that greatly affect the survival and growth of catfish include temperature and water pH with pH range of 6.5-8 and temperature of 250C-300C. The monitoring and measurement are still done manually by catfish farmers to get the temperature and pH parameter values without knowing the exact value of these measurements. According to those problems, this final project provides an information system on monitoring the water quality of catfish pond to facilitate monitoring, namely by using a device that is remotely controlled in real-time, and contains sensors needed for measurement so that it can measure the parameters from a different place. Each node in each pond contains a measurement system using a DS18B20 temperature sensor and a SEN0161 pH sensor that can measure temperature and pH. The system is using a method with several stages, namely the stages of design, implementation and testing. The measurement results from the temperature sensor and pH sensor are displayed on the web page in the form of graphs and tables.

Abstract

The Ledug Block is one of the areas in TAHURA R Soerjo which is experiencing fire. The fire causes the existing land cover to change or decrease, with the reduced land cover, the land will be easily exposed to surface runoff. This study aims to calculate the erosion rate in the TAHURA R Soerjo Ledug Block using the USLE equation, visual presentation of erosion using the Goegraphic Information System (GIS). This research was conducted in December 2018 in the rehabilitation area of Tahura R Soerjo Priug Ledug Block, Pasuruan. The method used is the Geographic Information System (GIS) whose data is sourced from calculations with the USLE method. The results of the study are the rain erosivity index (R) obtained from the month rainfall in 2018. The soil at the study site in each SUL is dusty clay. The vegetation in the research location in each SUL is in the form of bushes and added to SUL 3 there are several trees. The average erosion rate is 0.034 tons / ha / year. Erosion hazard classes that occur at the research location are included in class I (very mild). Enriching the land cover by planting trees with tree stands needs to be done so that the land is tightly closed and better withstand surface runoff.
