as much preliminary data as possible about humans,
circumstances or other symptoms. The point is pri-
marily to reinforce the hypotheses, in order to be able
to help strengthen old theories or within the frame-
work of composing new theories.

Coal mining business activities”
3.1.1 Regulations and Policies on the Existence
of Mines and Minerals in Indonesia
Article 33 of the 1945 Constitution mandates that the
earth, water and natural resources contained therein
be controlled by the state and utilized as much as pos-
sible for the prosperity of the people. The mandate
of the 1945 Constitution is the foundation of min-
ing and energy development to utilize the potential
wealth of mineral and energy resources that are op-
timally owned in supporting sustainable national de-
velopment. The mines, minerals and coal contained
in the Indonesian legal jurisdiction are non-renewable
natural wealth as the gift of God Almighty which has
an important role in fulfilling the lives of many peo-
ple. Therefore, the management must be controlled
by the State to provide real added value to the na-
tional economy in an effort to achieve prosperity and
equitable welfare of the people. Mining is an activity
of extracting precious and economically valuable de-
posits of deposits from the skin of the earth, both me-
chanically and manually on the surface of the earth,
beneath the surface of the earth’s water. The Govern-
ment of the Republic of Indonesia through Govern-
ment Regulation No. 27 of 1980 divides the excavated
material into 3 groups, namely:
1. Strategic excavation material called group A ex-
cavation consists of: petroleum, liquid bitumen,
frozen wax, natural gas, solid bitumen, asphalt,
anthracite, young coal, uranium radium, thorium
other radioactive minerals, nickel, cobalt, tin.
2. Vital excavation is also referred to as class B ex-
cavation consisting of iron, molybden, chromium,
tungsten, vanidium, titan, bauxite, copper, lead,
zinc, gold, platinum, silver, mercury, arsenic, an-
timony, bismuth, ytrium , rhutenium, cerium, and
other rare metals, beryllium, corundum, zircon,
power crystals, cryolite, fluorspar, barite, iodine,
bromine, clhor, sulfur.
3. Non-strategic and non-vital excavation materi-
als, also referred to as group C excavations.
These consist of: nitral, nitrite, phosphate, rock
salt (halite), asbestos, talc, mica, graphite, mag-
nesite, yarocyte, leucite, alum (alum ), ocher,
gemstones, semi-gemstone, quartz sand, kaolin,
feldspar, gypsum, bentonite, diatomaceous earth,
absorbent soil (fuller earth), pumice, trass, obsid-
ian, marble, slate, limestone, dolomite, calcite ,
granite, andesite, basalt, trachite, clay, sand, as
long as they do not contain group A or group B
mineral elements on a scale that is significant in
terms of mining economics.
The classification of the above excavation is insepa-
rable from the 1967 Basic Mining Law which con-
firms that the classification of minerals is based on
different roles for the nation and state. Group A is a
mineral that is very important for the country’s econ-
omy because it brings in relatively large foreign ex-
change. Group B is a mineral that concerns the liveli-
hood of many people, while group C is a mineral that
is needed for industrial or building materials.
Meanwhile, based on the criteria of mineral min-
ing commodities that can be increased, the added
value can be classified into 3 (three) groups, namely
metal minerals, nonmetallic minerals and rocks. The
description of each type of mineral mining commod-
ity is as follows:
1. The group of metal minerals is a type of metal
mineral mining commodity which includes ore:
copper, gold, silver, tin, lead and zinc, chromium,
molybdenum, platinum group metals, bauxite,
ore, iron sand, nickel, cobalt, manganese and an-
timony.
2. Nonmetallic mineral groups consist of various
types of non-metallic mineral mining commodi-
ties which include: calcite (limestone / lime-
stone), feldspar, kaolin, bentonite, zeolite, silica,
zircon and diamond.
3. The rock group is a type of rock mining com-
modity, among others: Toseki, Marble, Onik, Per-
lite, Slate (slate), Granite, Granodiorite, Gabro,
Peridotite, Basalt, Opal, Chalcedony, Chert (ri-
jang), Jasper, Chrysoprase , Garnet, Jade, Agat
and Topas.
In welcoming the ban on the export of raw mate-
rials for mining and minerals in January 2014, there
were 15 (fifteen) companies that stated readiness for
