Abstract

Batu bara adalah sumber energi untuk pembangkit listrik dan berfungsi sebagai bahan bakar (Sukandarrumidi, 1995). Stock opname batu bara merupakan kegiatan survei yang dilakukan di area coal yard untuk menghitung volume stockpile dan tonase batu bara setelah dikalikan dengan nilai densitas. Perkembangan teknologi pada bidang survei dan pemetaan atau pemodelan saat ini sudah sangat pesat. Salah satu alatnya pada saat ini adalah Terrestrial laser Scanner (Simbolon, 2017). Terrestial Laser Scanner mampu merekam sudut horizontal, sudut vertikal, dan jarak antara objek dengan alat yang kemudian ditransformasikan kedalam koordinat kartesian 3 dimensi. Penelitian ini akan dibuat visualisasi dari pemodelan 3 dimensi stock opname batu bara dari hasil pengukuran terrestrial laser scanner dengan berbagai representasi dari metode triangular mesh. Output yang dihasilkan merupakan pemodelan 3 dimensi dari objek batu bara dari berbagai macam mode, seperti wireframe mode, shaded mode, dan textured mode. Pada perhitungan volume menggunakan metode Prismoidal didapatkan hasil sebesar 257911.843 m3. Pada metode Grid, didapatkan hasil volume batu bara sebesar 264026.111 m3. Pada metode Kontur didapatkan hasil volume batu bara sebesar 239984.425 m3. Pada metode TIN didapatkan hasil volume batu bara sebesar 262171.925 m3. Dari presentase perubahan volume yang didapatkan, metode yang masuk dalam toleransi terhadap metode prismoidal adalah metode TIN dan grid dengan selisih volume sebesar -2%. Jika dibandingkan dari ketiga model visualisasi tersebut antara shaded mode dan textured mode tidak memiliki perbedaan yang signifikan, namun texture mode menunjukkan hasil yang paling mendekati dengan kondisi di lapangan

Coal is a source of energy for power generation and functions as fuel (Sukandarrumidi, 1995). Coal stock taking is a survey activity carried out in the coal yard area to calculate the stockpile volume and coal tonnage after multiplying by the density value. Technological developments in surveying and mapping or modeling are currently very rapid. One of the tools at this time is the Terrestrial Laser Scanner (Simbolon, 2017). The Terrestrial Laser Scanner is capable of recording horizontal angles, vertical angles, and distances between objects and tools which are then transformed into 3-dimensional Cartesian coordinates. This research will be made visualization of 3-dimensional modeling of coal stock taking from the measurement results of terrestrial laser scanners with various representations using the triangular mesh method. The object of this research is coal stock taking. The resulting output is a 3-dimensional modeling of coal objects from various modes, such as wireframe mode, shaded mode, and textured mode. The results of volume using Prismoidal method is 257911.843 m3. In the Grid method, the resulting coal volume is 264026.111 m3. In the Contour method, the volume of coal is 239984.425 m3. In the TIN method, the volume of coal is 262171.925 m3. From the percentage change in volume obtained, the method that is included in the tolerance of the prismoidal method is the TIN and grid method with a volume difference of -2%. When compared to the three visualization models, there is no significant difference between the shaded mode and the textured mode, but the texture mode shows the results that are closest to the conditions in the field
