Tanaw

Tanaw is a farm management app for Mangima Estate, a pineapple farm. It shows the team what to do in each field this week, and whether there will be enough fruit for their customers’ orders. Client work, shown from the working prototype.

The problem

The farm is divided into fields. Each week the team decides which fields to treat so their plants flower at the same time, which sets when the fruit will be ready. They also need to know if there will be enough fruit for every order.

The idea

Every field on a satellite map, with the harvest, the orders, the work crews and the weather alongside it. The app opens on what needs deciding today.

What I did

The design, and a working prototype of every screen.

Today’s decisions come first

The left side lists this week’s jobs: treat two fields tonight, harvest one and check on another. Open a job and the right side explains why, including how much fruit is at stake. New jobs appear when the weather or the plant checks change.

Enough fruit for every order?

The harvest plan compares the fruit expected each week with what customers have ordered. Weeks that fall short turn red, along with the fields that could make up the gap.

Each buyer with its weekly volume, and the weeks that fall short — Orders

One buyer’s order: its weekly volume, its short weeks and the next three shipments — One customer

Every field on a satellite map

The map colours every field by how far along its plants are. It also shows how big the plants are, how healthy they look and how wet the soil is.

Blocks: the map with blocks coloured by stage, growing, fruit forming, harvesting and fallow, and a table of every block below with stage, area, plant weight, vigour, soil water, harvest and the next job — Fig. 3

Down to single plants

Inside a field, each dot is one plant the team has weighed. Red dots are plants still too small to treat, so the team can see where they are before anyone sprays.

Block B-14 up close on the satellite map: white dots for plants weighed at 2.5 kg or more, red dots and a hatched north end for those under, the plant weight panel on the left, the week 11 forcing panel on the right and a plant weight chart — Fig. 4

Force tonight: the week it lands, the fruit it adds, and why now: plant weight, the short week, cool nights and the rain forecast — Treat tonight

Plant weight on 18 September: 34 plants at 2.5 kg or more, 5 under, the north end 1.6 ha, B-16 the same night, B-18 harvesting, and Log sample — Plant checks

Work crews and weather in one week

Work crews, the sprayer, the people who check the fields and the trucks are all planned on one weekly view. Spraying happens at night and needs a few dry hours after, so the forecast is shown hour by hour.
