Abstract
RINGKASAN
Indonesia merupakan negara yang kaya akan potensi sumberdaya alam yang
dimiliki. Ada banyak potensi yang masih belum tereksplorasi yang bisa
dimanfaatkan demi kepentingan orang banyak. Seiring dengan perkembangan
jaman maka pembangunan secara fisik seperti pembangunan insdustri dan
perumahan pun meningkat pesat. Salah satu potensi bahan galian mineral batuan
(UU No.4 Tahun 2009 tentang pertambangan mineral dan batubara) pada wilayah
penelitian adalah batupasir dan breksi. Penelitian ini dilakukan untuk menghitung
besaran sumberdaya pada wilayah penelitian PT. Tbek Engineering yang berada di
Desa Limpung, Kecamatan Gringsing, Kabupaten Batang, Provinsi Jawa Tengah.
Luas wilayah penelitian sebesar 250.349 m2
.
Metode penelitian yang dilakukan dengan cara melakukan studi pustaka,
pengamatan pada penyebaran batupasir, pengumpulan data sampai dengan
kesimpulan dan saran. Hasil perhitungan dengan metode cross section sebesar
13.068.222 m3
sedangkan dengan metode contour sebesar 14.599.983 m3
. Hasil
estimasi dengan metode cross section lebih kecil dibanding dengan metode
contour, ini dikarenakan metode cross section jarak antar sayatan sebessar 50 m
dengan asumsi permukaan dianggap sama atau linier, sedangkan metode contour
jarak antar penampang kontur sebesar 1 m sehingga menjadikan lebih akurat dan
hasilnyapun semakin besar. Untuk selisih kedua metode sebesar 1.531.761 m3
.
ABSTRACT
Indonesia is a country that is rich in natural resource potential. There are many
unexplored potentials that can be exploited for the benefit of many people. Along
with the changing times, physical development such as industrial and housing
developments also increased rapidly. One of the potential mineral rock minerals
(Law No.4 of 2009 concerning mineral and coal mining) in the research area is
sandstones. This research was conducted to calculate the amount of resources in
the research area of PT. Tbek Engineering located in Limpung Village, Gringsing
District, Batang Regency, Central Java Province. With a research area of
250,349 m2
.
The research method is carried out by conducting literature studies,
observing the distribution of sandstones, collecting data to conclusions and
suggestions.The results of the calculation using the cross section method are
13.068.222 m3 while the contour method is 14.599.983 m3
. The estimation results
with the cross section method are smaller than the contour method, this is because
the cross section method the distance between the incisions is 50 m with the
assumption that the surface is considered the same or linear, while the contour
method the distance between contour cross sections is 1 m so that it makes it
more accurate and the results are increasingly big. For the difference between the
two methods is 1.531.761 m3
