Abstract

This research aims to determine the CTDI value on a CT Scan aircraft using Dose Profiler and to determine the comparison of the CTDI (Computed Tomography Dose Index) value on the surface of each measurement position. The measurement method was carried out by measuring the CT Scan radiation dose with the CTDI value on the phantom using a RaySafe multimeter at a voltage of 130 kV, using a thickness of 10 mm, a time current accuracy of 100 mAs, 200 mAs and 300 mAs. The research results show the dose received on the surface of each type of phantom position with different time current accuracy respectively for a time current of 100 mAs at the center (9.139 mGy), type 1 (9.606 mGy), type 2 (9.170) type 3 (9.221) , and type 4 (9,210). A time current of 200 mAs is found at the center (9,110 mGy), edge 1 (9,578 mGy), edge 2 (9,546 mGy), edge 3 (9,224 mGy), and edge 4 (9,200 mGy). A time current of 300 mAs is found at the center position (18.39 mGy), edge 1 (19.33 mGy), edge 2 (19.18 mGy), edge 3 (18.48 mGy), and 4 (18.51 mGy) . Time-current variations affect the radiation dose that can be received by the phantom and have a linear influence on the CTDIvol value.

Abstract

The process of analysing the quality of radiographic images produced by X-rays with 48 kV and 50 kV tube voltages in Covid-19 patients using ImageJ software has been carried out. The images analysed are the results of thoracic radiographic examinations using the same electric current strength in Covid-19 patients with 48 kV and 50 kV voltage variations. The image results come from converting the analogue format to digital format for further processing. The analysis method uses the FFT (Fast Fourier Transform) method and histogram analysis. Image quality was assessed based on pixel distribution, contrast and SNR (Signal to Noise Ratio) parameters. Visualisation of the distribution can be seen based on histogram analysis. In the histogram, the prominent intensity shows the pixel intensity and the peak width shows the contrast range in the image. If the histogram graph is distributed in the minimum area, the image tends to be dark and vice versa, if the histogram graph is more in the maximum area, the image tends to be bright. The results show that the 48 kV voltage has a more even distribution but has low contrast and SNR values compared to the 50 kV voltage. The results of this study provide an overview of the selection of kinetic parameters in patients and optimisation of X-ray technical parameters to obtain maximum image quality in radiographic diagnosis.

Abstract

This study aims to determine the absorption spectrum of the functional groups of snakehead fish scale collagen before irradiation and the effect of the dose of Cesium-137 irradiation on the functional groups in snakehead fish scale collagen. The extraction method used is acid extraction. Measurement of the absorption spectrum of collagen samples from snakehead fish scales using an FTIR spectrophotometer. Samples were irradiated using doses of 10 mGy, 30 mGy and 50 mGy. The results of the functional group values before irradiation produce amide A, amide I, amide II and amide III which fill the absorption area of the functional group. The results of the functional group values produced after irradiation for a dose of 10 mGy produced amide I, amide II and amide III which filled the absorption area. Amide A and amide B do not fill the absorption region at a dose of 10 mGy. Doses of 30 mGy and 50 mGy produced amide A, amide I, amide II and amide III which filled the absorption area. Amide B did not fill the absorption area at doses of 30 mGy and 50 mGy. Amide groups that are not detected or do not meet standard collagen functional group standards can be caused by the chemical composition of the fish scale extraction process.

Abstract

This study aims to examine the mechanical characteristics of briquettes made from a mixture of coconut shells, corn cobs, and cow dung with tapioca adhesive. Briquettes were tested based on their mechanical properties for density using a vernier caliper and for compressive strength and hardness using a Universal Testing Machine (UTM). Samples were made in different mixture compositions with particle sizes of 60 mesh and 100 mesh. The results showed that variations in particle size and material composition significantly affected the quality of biobriquettes. Biobriquettes with a particle size of 100 mesh have higher density, compressive strength, and hardness than 60 mesh particles. The material composition with a ratio of 44:44:12 produced the best characteristics with a density value of 0.94 g/cm³, compressive strength of 9.32 kg/cm², and hardness of 41.10 HB. This study proved that biobriquettes meet the criteria as an environmentally friendly alternative fuel and have the potential to reduce biomass waste while providing efficient renewable energy.

Abstract

Isodosis contour analysis using surfer type 21 software has been conducted in the radiology installation of Labuang Baji Hospital Makassar to determine the safest distance for radiology medical personnel while in the X-ray aircraft area. Measurements were carried out before and during exposure to a water phantom using an X-ray aircraft with a surveymeter. Radiation exposure rates were measured at 8 track locations in the X-ray aircraft room, consisting of 16 points located on the track (A, B, C, D, E, F, G, H) at 1 m and 1.5 m heights. The processed data showed that the highest radiation exposure dose was in the E-1 track (in front of the X-ray plane), which was 0.001791 mSv with a radiation dose exposure rate of 43.320 mSv/hour for a height of 1 m and 0.001228 mSv in the A-1 track for a height of 1.5 m with a radiation dose exposure rate of 29.7997 mSv/hour. The isodose contours also show variations in the number of passes and different colors for each radiation exposure dose value. The findings of this study indicate that the radiation exposure dose is 0 mSv at a distance of more than 2 m from the X-ray plane, so the radiologist is within safe limits to perform radiodiagnostic procedures.

Data yang dibutuhkan pada kegiatan ini ada 2 yaitu data geologi dan data geofisika.  Data geologi diperoleh dari hasil pengamatan struktur batuan di atas permukaan dan data kedalaman sumur warga di sekitar lokasi kegiatan. Sedangkan data geofisika, diperoleh menggunakan alat resistivitimeter. Analisis data yang dilakukan yaitu menggunakan Software Microsoft Excel, Notepad, QGis, IPI2WIN, dan Res2DInv untuk mendapatkan model bawah permukaan. Model ini diinterpretasi menggunakan tabel resistivitas batuan untuk memetakan air tanah di Kaki Gunung Latimojong Kabupaten Enrekang. Setelah dilakukan interpretasi maka dilakukan penentuan titik bor air tanah. Lapisan air tanah ditemukan pada 2 titik pengukuran dengan kondisi yang tipis. Hal ini disebabkan oleh formasi batuan di Kaki Gunung Latimojong didominasi batuan beku yang berasal dari formasi latimojong. Titik pengeboran air tanah pada Kaki Gunung Latimojong terdapat pada koordinat 03°25’00.00” S dan 119°59’24.53” E ketinggian 1479 mdpl serta pada 03°25’09.94” S dan 119°59’18.74” E ketinggian 1463 mdpl. Kata Kunci: Air Tanah, Metode Geolistrik, Kaki Gunung Latimojong    Abstract The focus of this activity is to help the community find out the potential of groundwater and determine groundwater drilling points using the geoelectric resistivity method as a solution to the water crisis at the foot of Mount Latimojong, Enrekang Regency. The location of the activity is at the foot of Mount Latimojong, Enrekang Regency with a total of 3 Schlumberger configurations. Data collection involves the government and local residents. There are 2 data needed for this activity, namely geological data and geophysical data.  Geological data was obtained from observations of rock structures above the surface and data on the depth of residents' wells around the activity location. Meanwhile, geophysical data was obtained using a resistivity meter. Data analysis was carried out using Microsoft Excel, Notepad, QGis, and IPI2WIN software to obtain a subsurface model. This model is interpreted using rock resistivity tables to map groundwater at the foot of Mount Latimojong, Enrekang Regency. After the interpretation is carried out, the groundwater drilling point is determined. The groundwater layer was found at 2 measurement points in a thin condition. This is because the rock formations at the foot of Mount Latimojong are dominated by igneous rocks originating from the Latimojong formation. The groundwater drilling point at the foot of Mount Latimojong is located at coordinates 03°25’00.00” S and 119°59’24.53” E at an altitude of 1479 mdpl and at 03°25’09.94” S and 119°59’18.74” E at an altitude of 1463 mdpl Keywords: Groundwater, Geoelectrical Method, Foot of Latimojong Mount

Abstract

Vaksinasi COVID-19 merupakan salah satu kegiatan yang dilakukan untuk melindungi tubuh  dengan menciptakan respons antibodi (sistem kekebalan) dengan tujuan meminimalkan penularan virus. Penelitian ini bertujuan untuk mengetahui faktor yang berhubungan dengan penerimaan orang tua murid terhadap vaksin COVID-19 pada anak Sekolah Dasar usia (6-11 tahun). Penelitian ini menggunakan pendekatan deskriptif non eksperimental. Populasi dalam penelitian adalah seluruh orang tua murid yang memiliki anak usia sekolah (6-11 tahun) di Kota Makassar yang dikategorikan layak mendapatkan vaksinasi, yaitu sekitar 264.000 orang dan besar sampel sebanyak 1.073 orang tua murid. Teknik pengambilan sampel yang digunakan, yaitu snowball sampling. Hasil penelitian menunjukkan bahwa sebagian besar orang tua menerima vaksin anak 83,8% dibandingkan dengan yang menolak 12,6%. Ada lima alasan mengapa responden menerima vaksin. Alasan yang paling banyak, yaitu “Keinginan sendiri Karena sadar akan manfaat vaksin anak” sebesar (75,1%) atau sebanyak 675 orang, sedangkan alasan yang paling sedikit, yaitu “ikut-ikutan dengan orang tua murid yang lain” sebesar (0,1%) atau sebanyak satu orang dan terdapat enam alasan mengapa responden menolak vaksin. Alasan yang paling banyak, yaitu “Takut terhadap efek samping vaksin” sebesar (8%) atau sebanyak 86 orang, sedangkan alasan yang paling sedikit, yaitu “Karena dari lahir anak saya tidak pernah di vaksin” sebesar (0,3%) atau sebanyak 3 orang. Disarankan kepada seluruh pihak terkait agar saling bersinergi dalam melakukan sosialisasi terkait pentingnya vaksin COVID-19 pada anak sebagai salah satu upaya dalam mencegah dan menanggulangi penyebaran virus COVID-19.
