IndexError & AttributError-CodePudding

can someone help me fixing this error? im new in python and im using keggle.

import numpy as np
import pandas as pd
import matplotlib.pyplot as plt
import sklearn

dataset = pd.read_csv('../input/datacoba2/Data Penjualan1.csv', sep=",")
x = dataset.iloc[:, :-1:].values
y = dataset.iloc[:, 1].values

in this situation i get error message "IndexError: single positional indexer is out-of-bounds"

dataku = pd.DataFrame(dataset)
plt.scatter(dataku.BiayaProduksi,dataku.NilaiPenjualan)
plt.xlabel("Biaya Produksi")
plt.ylabel("Nilai Penjualan")
plt.title("Grafik Biaya Produksi VS Nilai Penjualan")
plt.show()

and in this situation i get error message "AttributeError: 'DataFrame' object has no attribute 'BiayaProduksi' "

my csv file look like this
