Abstract

Sensitive magnetic field sensor based on compensated double pick up coil has been developed. In order to confirm sensitifity of modified design, experiment carried out in two steps. Firstly, sensitify of conventional design is clarified. Here pick up coil as an active sensor and solenoid as an exitation coil is separately made. Secondly, modified sensor of integrated configuration is developed. Here for both active flux gate sensor and the exitation coil is made in same one core magnetic. Ferrite and standar foil soft magnetic is utilized in this experiment. In attention, frequency of 50 Hz is used for the whole experimens. A result showed that sensitvity of the integrated configuration sensor is much larger than conventional one. Then, power consume of the integrated flux gate sensor is much lower than conventional. Finally, a range measurement of the integrated configuration sensor can be realized less than 20 T which potential may perhaps sense a change of natural local magnetic field.

Abstract

Computational simulations of proton therapy with a pencil beam collimator for craniopharyngioma have been done using MCNP6. A pencil beam was radiated towards cube shaped tumor cells in size 1.2 cm, located at a 5.4 cm depth from the surface of the scalp. A 0.1 cm pencil beam was radiated from the left 19.6 cm from the scalp. The cube of tumor cell is divided into the front layer, middle layer, and back layer. Each layer of the tumor cell is divided into 9 cubicles, thus there are 27 cubicles. Using various energy from 108 MeV to 115 MeV and various intensity of energy for each irradiation, it produces the dose for each cubicle in unit MeV/gram per proton. The best isodoses occurred in 5 variations of energy which is 108.2; 111.2; 113.4; 114.7 and 115 MeV. The healthy organ that received the largest dose of the proton is the brain, it is (7.38±0.01)×10-2 MeV/gram per proton, or only 0.412% compared to the tumor cell dose.

Abstract

Proton therapy modeling for treating craniopharyngioma tumors was conducted using a pencil beam collimator, and variations in beam directions were performed using MCNP6 software. The simulation was carried out on a head and neck phantom with the tumor cells modeled within a cubic irradiation area geometry with a 1.2 cm side length, divided into 27 small cubic voxels with a small voxel side length of 0.4 cm. The radiation source from the irradiation area's right, left, and top directions, with a diameter of 0.4 cm, was directed at each cubic voxel. Variation in radiation source directions indicated that irradiation from the right direction of the irradiation area is the most recommended approach, with a dose uniformity level of 83.47%. Healthy organs surrounding the irradiation area received lower doses than those obtained by tumor cells, and the majority remained below the Organ At Risk (OAR) threshold. Healthy organs received the highest dose, particularly in the brain region, at a relative 0.46% compared to the total dose received by tumor cells.

Abstract

ABSTRACT: The Rekso Pustoko Mangkunegaran Library has various types of historical manuscripts, covering history from ancient to modern periods. The existence of these collections is certainly very useful for writing history, especially the history of Java. Unfortunately, there are still many historical researchers in Indonesia who use colonial archival sources such as Besluit, Algemeen Verslag, Memorie van Overgave and documents such as Staatsblad, Rijksblad and Regeering Almanac instead of using existing historical manuscripts. This is due to the difficulties experienced by historical researchers in reading manuscripts which in terms of material are written by hand and use Javanese language and letters. To overcome this problem, it is necessary to catalog the manuscripts. The catalog of historical manuscripts in addition to containing the manuscript code number also contains a synopsis of the contents of the manuscript. This, in addition to making it easier for researchers to find manuscripts, also helps in understanding the contents of historical manuscripts from the Rekso Pustoko Mangkunegaran collection. The purpose of this service is to catalog the historical manuscripts of the Rekso Pustoko Mangkunegaran collection. ABSTRAK: Perpustakaan Rekso Pustoko Mangkunegaran mempunyai berbagai jenis manuskrip sejarah, meliputi sejarah dari periode kuno hingga modern. Keberadaan koleksi-koleksi ini tentu sangat bermanfaat bagi penulisan sejarah terutama sejarah Jawa. Sayangnya, masih banyak peneliti sejarah di Indonesia yang lebih banyak menggunakan sumber arsip kolonial seperti Besluit, Algemeen Verslag, Memorie van Overgave maupun dokumen seperti Staatsblad, Rijksblad dan Regeering Almanak dibandingkan memanfaatkan manuskrip sejarah yang ada. Hal ini dikarenakan kesulitan yang dialami peneliti sejarah dalam membaca manuskrip yang dari segi material ditulis dengan tangan serta menggunakan bahasa dan huruf Jawa. Untuk mengatasi masalah ini diperlukan upaya katalogisasi manuskrip. Katalogisasi manuskrip sejarah selain berisi nomor kode manuskrip juga berisi sinopsis dari isi manuskrip. Hal ini selain mempermudah peneliti dalam menemukan manuskrip juga sekaligus membantu dalam memahami isi manuskrip sejarah koleksi Rekso Pustoko Mangkunegaran. Tujuan dilakukannya pengabdian ini adalah untuk membuat katalog manuskrip sejarah koleksi Rekso Pustoko Mangkunegaran.

Abstract

The alpha therapy modeling was performed for the treatment of glioblastoma brain cancer using MCNP6 software. The simulation used a head and neck phantom geometry, with a spherical shape of the radiation direction of the cancer cells with a radius of one cm divided into 27 targets. One radiation source is directed to each target center of the cancer cells with five energy variations, namely (430, 425, 415, 410, and 400) MeV. The simulation results are in the form of a distribution of absorbed doses in all targets and healthy cells around them. The simulation results show an average dose distribution of (1.2902 ± 0.0024) 10-11 Gy/alpha with an isodose level of 69.75%. The healthy organ that receives the largest dose and secondary particle distribution after cancer cells is the brain, with an accumulative dose of (1.7446 ± 0.0033) 10-15 Gy/alpha. The dose distribution on cancer cells shows that the irradiation time to kill glioblastoma cancer cells is (1456±0.14) seconds with an alpha current of 1 nA.

Abstract

Pneumonia has been detected using Machine learning. The stages in this study began with preprocessing in 4 stages: resizing, cropping, filtering using a high pass filter, and Adaptive Histogram Equalization. The feature extraction process continued with 22 Gray Level Co-occurrence Matrix (GLCM) features and classification using K-Nearest Neighbor (KNN). The image used was 150 data sets for training on the classification of 3 classes with a ratio of 50:50:50 while training on two classes was 50 bacterial pneumonia and 50 viral pneumonia. The most optimal training data accuracy results were obtained using the angle direction on the GLCM, namely 135o with the KNN classification (k = 3). For the classification of two classes Using 40 data sets, an accuracy of 91% was obtained, while testing for three classes with 60 data sets was 83.3%.

Abstract

This research was conducted to identify wood filaments and ASA as potential organ phantoms based on material density, CT number, electron density, effective atomic number, and radiation dose parameters. The thickness and density of the samples were varied to determine the effect on each parameter. The sample image was obtained from a CTScan radiology test with the same exposure factor. The potential of samples as organ phantoms varies for each parameter. In wood filament samples, a thickness of 1 cm to 2 cm with a density of 20% can potentially be a lung organ phantom. Meanwhile, at a thickness of 5 cm with a density of 100%, it can potentially act as a phantom for bone, liver and muscle organs. In ASA filament samples with a thickness of 1 cm to 5 cm with a low density of 20%, it has the potential to be a lung organ phantom and at a density of 100% it has the potential to be an adipose tissue phantom.
