Abstract

Padang city is the capital of West Sumatera province which is developing in various fields, one of them is banking field. The amount of ATM distribution makes people difficult to memorize and know where the ATM location. Likewise with gas stations, many of the community, immigrants and tourists who do not know the location of the city Padang SPBU in the city of Padang. Through the design and development of location-based mobile data collection applications android this can facilitate the community, immigrants and tourists in finding information on the location of banks, ATMs and gas stations in the city of Padang. The method used is the method of data collection and survey analysis, while the design method using SDLC method with waterfall model. This application uses haversine formula as a calculation method that is considered suitable for nearest location search because in the calculation process to take into account the curvature of the earth so it can produce more accurate results. With this application android phone users can find out the location of banks, ATMs and gas stations that are closest to where they are located.

Abstract

Nursery is the activities in order to the plants grow uniformly. One of the factors affecting cacao nursery is watering. It aims to fulfill the water needs of plants. Water is important because it is a major component in the cells as compiler of plant tissue. So, the objective of this study was to determine the best volume of water on the growth of cacao seedlings. The research was conducted on September 2019 until January 2020 located in the greenhouse of 3rd Campus Andalas University, Dharmasraya, West Sumatra. The research method was a Completely Randomized Design (CRD) by 4 treatments and 5 replications so obtained 20 experimental units, each of it consisted of 2 cacao seedlings so that 40 plant samples were obtained. Several treatment levels were 150 ml water volume / polybag (V1), 300 ml water volume / polybag (V2), 450 ml water volume / polybag (V3), and 600 ml water volume / polybag (V4). The observation variables were plant height, leaf width, stem diameter, number of leaves, root length and plant dry weight. Regression analysis was performed to know the relationship among observed variables. The results showed that the application of 450 ml water / polybag (V3) generate the best results for plant height, leaf width, stem diameter, number of leaves, plant dry weight, and root length of 1-4 months cacao seedlings. The result of regression analysis showed that there was a close relationship among the plant dry weight of cocoa seedlings with the plant height, stem diameter and number of leaves.
