Abstract

Water resources are important factors in food production. Those are very vital and strategic to meet food needs and food security. As water is scarce both in terms of volume and distribution throughout the year, reliable water management is needed. To support this water management, the accurate data is needed. However, the complete tabular data is not enough. It is because the existing tabular data does not provide the various activities and events based on time and place spatially and detail enough for planning purposes at the sub-district level. The researchers use high-resolution satellite imagery data that have been pre-processed with the geometric and radiometric corrections. They are used as one of the layers in the working map, so it is easier to provide the depiction of irrigation network objects, to find out the location of rice fields that have not been irrigated and the location of damaged irrigation networks. The depiction of the working map can also be used to map irrigation networks and their network conditions. Through this work, it has been shown that the researchers can map irrigation networks in detail for operational planning at a sub-district level with the help of technology, in particular for developing countries that is difficult or even impossible to do in the past.

Abstract

The evolution of information technology affects many organizations in Indonesia, especially telco companies. Indosat Ooredoo Hutchison or more commonly known as PT Indosat, Tbk. or Indosat, a telco company in Indonesia has implemented a mobile application called Simpel for use by the salespeople to sell products. Currently, the app has been used by 60% of the users for less than 10 transactions in a month which resulted in only 9% of total revenue generated by the retailer app. This occurrence gave a challenge for Indosat to manage and increase the transaction count in the aforesaid app. This study aimed to analyze the factors influencing a salesperson’s decision to more frequently use Simpel to sell products. Every telco company can learn from this research to enhance app features better. The analysis is based on human behavior in information systems environment. The combination of UTAUT and other variables was used in this study. The total sample was obtained from 467 respondents who registered and used the app. Analysis were conducted using the structural equation models to learn the impact that performance expectancies, effort expectancies, social influence, facilitation conditions, and quality of sales applications have towards behavioral intention to use mobile app; and to learn the impact of behavioral intention, social influence, and facilitating conditions towards improving the sales app usage behavior.
