Abstract

Proton-neutron interaction that makes up deuteron is a mixture state of ????13 dan ????13, which are each associated with a state ????=0, ????=1 and ????=2, ????=1. In the proton-neutron interaction, there are particle exchanges of medium range (1 fm≤????≤2 fm) i.e. scalar meson exchange and the long range (????>2 fm) i.e. one pion exchange. The electromagnetic properties of non-relativistic deuteron in the ground state can be found from the coupled differential equation, such as magnetic dipole moment, 〈????D〉=0.856521???????? and electrical quadrupole moment, 〈????D〉=0.00291396 b.

Abstract

Tujuan dari penelitian ini adalah untuk mengetahui struktur bawah permukaan jalur Sesar Opak berdasarkan model suseptibilitas dan SVD dengan metode geomagnet. Pengambilan data dilakukan menggunakan Proton Precession Magnetometer Geometric tipe G-856 dengan 77 titik pengukuran dan jarak antar titik pengukuran +2 km. Pengolahan data dilakukan melalui koreksi variasi harian, koreksi IGRF, SVD, dan reduksi ke kutub. Pemodelan dilakukan dengan menganalisis anomali medan magnet yang telah direduksi ke kutub. Hasil pemodelan solid model menunjukkan bahwa Formasi Semilir dengan nilai suseptibilitas (0 – 100) ×10-3, Formasi Merapi Muda dengan nilai suseptibilitas (0 – 2) ×10-3, dan Formasi Nglanggran dengan nilai suseptibilitas (0,6 – 70) ×10-3. Hasil pemodelan SVD dan solid model menunjukkan keberadaan Sesar Opak.

Abstract

Heat transfer in turbulent flows is one of the essential topics in power plants and thermal-based engineering. This study aims to analyze the effects of density changes due to heat transfer in a turbulent environment—which is usually neglected because it can cause instability in a simulation. We simulate an available experimental case of turbulent heat transfer of air with OpenFOAM: one with an incompressible approach (no density change) and another with a compressible treatment. The simulation geometry is a 0.75 × 0.75 m2 square cavity, where its left and right walls are kept at a temperature difference of 40 K. We compare and analyze the temperature, velocity, and turbulence kinetic energy profiles of both simulation results against the experimental data. We found that from all qualitative and quantitative comparisons, the change in density plays a vital role in turbulent heat transfer. The compressible treatment gives better results than the incompressible: the neglection of density change causes a significant difference with the experimental data. Thus, we strongly recommended incorporating compressibility in simulating heat transfer in turbulent flows.

Abstract

This research was aimed to determine the distribution pattern of magnetic field anomaly and to identify the lithology of underground structure in Bribin Karst using geomagnetic method. Research location was Semanu Sub-district, Gunungkidul Regency at UTM coordinate of 464061 mT-464929 mT and 9111097 mU-9111970 mU. The data were taken using G-5 Proton Precession Magnetometer (PPM) by looping method. The result showed that the distribution pattern of the magnetic field anomaly in Karst Bribin has value of 330 nT - 530 nT and anomaly values reflecting the system of Bribin River has value of 400 nT-460 nT. The lithology of underground structure in Karst Bribin has susceptibility value of -0.069 (in SI) - 0.0661 (in SI) with depth 200 m associated with limestone, tuff, gypsum, rock salt, and minerals calcite and anhydrite and the lithology associated with the system of Bribin River has susceptibility value -0.069 (in SI) associated with gypsum, rock salt, and minerals anhydrite.
