PT Cinta Flora is a firm specializing in developing Bonsai. The firm has three choices regarding when they will harvest and able to sell the Bonsai in the next 5 years, 10 years or 15 years. The firm started its Bonsai's development on January 1, 2020. The firm has 1-hectare area for its Bonsai. The firm's marketing department has surveyed the Bonsai's market price and estimate the following expected selling price:

Bonsai quality	Price per bonsai
Diamond	IDR 20.000.000
Gold	IDR 5.000.000
Standard	IDR 1.000.000

The Bonsai's price increases below the inflation rate. According to the local government statistical data, the inflation rate is expected to be 5 percent per year. An actuary believes that 2 percent per year is an appropriate growth rate below the inflation rate. PT Cinta Flora executives are considering when to harvest the Bonsai. They have possible scenarios below:

Time to Harvest	Harvest unit of bonsai	Diamond	Bonsai quality gold	standard
1 Jan 2025	800	10%	20%	70%
1 jan 2030	900	10%	40%	50%
1 jan 2035	900	15%	35%	50%

The firm's operational manager expects that there would be 10 percent losses of every Bonsai at every quality due to incidental damage. The entire cost of harvesting is expected to be Rp 80.000,- per Bonsai. Sales and administrative expenses (fully paid in cash) are expected to be Rp 60.000,- per Bonsai. Regrettably, the 10 percent losses of harvested Bonsai still incur operational expenses because the damaged Bonsai shall be carefully and properly cleared. The firm's executives budget the operational costs to increase at the inflation rate. The operational costs are as follows:

Operational	Cost per 1000 square meter
Razing	IDR 20.000.000
Watering	IDR 25.000.000
Monitoring	IDR 60.000.000
Fertilizer	IDR 10.000.000

All cash flows are assumed to occur during the harvest year. The firm's executives estimate that the nominal required return rate is 12 percent, and the tax rate of 25 percent.
