Abstract

Harga cabai yang turun saat panen melimpah tentu sangat merugikan petani. Hal tersebut perlu segera ditangani dengan cara memperlama masa simpan cabai menggunakan tekonologi tepat guna melalui program pengabdian kepada mayarakat. Tujuan program tersebut adalah memperkenalkan teknik pengeringan cabai menggunakan alat pengering cabai. Metode pelaksanaan pengabdian menggunakan metode ceramah interaksif dan praktek tentang teknologi pengolahan produk cabai mentah hingga menjadi cabai kering menggunakan alat pengering cabai. Hasil yang diperoleh adalah terciptanya alat pengering cabai sederhana berbahan bakar gas. Alat tersebut dibangun menggunakan kombinasi bahan logam (90%) dan kayu (10%) berukuran 80 x 50 x 120 cm3, dengan daya tampung hingga ± 7 kg cabai rawit mentah. Cabai rawit merah dan cabai rawit hijau mengalami penyusutan berat masing-masing sekitar 80% dan 90% dengan warna produk sangat kontas. Proses pengeringan dengan alat pengering lebih cepat (6 jam) dibandingkan dengan cara konvensional (7-10 hari). Berdasarkan hasil kuisioner, tingkat keberhasilan pelaksanaan program pengabdian tersebut di atas 90%.

Abstract

Radioterapi kanker serviks pada pesawat Linac menggunakan berkas photon energi 6 MV dengan teknik 3 Dimension Conformal Radiotherapy (3DCRT) dan Intensity Modulation Radiation Therapy (IMRT). Perencanaan radioterapi pada tehnik 3DCRT dan IMRT  kemudian dibandingkan dengan menganalisis distribusi dosis atau planning target volume (PTV) coverage melalui Conformity Index (CI) dan Homogeneity Index (HI) serta Organ At Risk (OAR) dimana organ beresiko yang diperhatikan adalah rektum. Pada penelitian ini menggunakan 30 data pasien kanker servik di Instalasi Radioterapi RSUP Sanglah Denpasar dengan perencanaan menggunakan box system  pada teknik 3DCRT dan teknik IMRT dengan sudut rotasi 00, 900, 1800, dan 2700 dan dosis radiasi 5000 cGy. Perbandingan kedua teknik ini dilakukan dengan menganalisis kurva Dose Volume Histogram (DVH) pada PTV coverage yang terdapat pada komputer Treatment Planning System (TPS). Hasil penelitian ini menunjukan nilai rata-rata CI pada tehnik 3DCRT adalah 1,017542 sedangkan pada tehnik IMRT sebesar 1,019668, dengan uji mann whitney (Asymp.Sig =0,492). Demikian juga dengan nilai HI, dimana pada tehnik 3DCRT rata-ratanya adalah 0,089494 sedangkan pada tehnik IMRT sebesar 0,093126 denga uji mann whitney (Asymp.Sig = 0,487), kedua nilai CI dan HI tidak signifikan. Sedangkan persentase dosis rata-rata organ rektum pada kedua teknik penyinaran 3DCRT dan IMRT berturut-turut yaitu 96% dan 87% dengan hasil uji statistik diperoleh nilai Asimp.Sig = 0.000 yang berarti signifikan. Radioterapi kanker serviks dengan menggunakan teknik IMRT dapat meminimalisir dosis serap pada OAR (rektum).

Abstract

A study has been carried out on the estimation of X-ray dose on hereditary effects on conventional radiography. The research was conducted at the Bali Academy of Radiodiagnostic and Radiotherapy Engineering using a Raysafe X-Ray Multimeter. Secondary data was obtained in the form of results of checking the output voltage (kV), exposure time (ms) and exposure (mGy). The data obtained are then grouped according to the voltage used. The data is used to calculate the Entrance Surface Dose (ESD) value, which is then used to find the value of the Hereditary effect on the examination of each organ. In this study, the lowest ESD value was found at the use of a voltage of 40 kV, namely 0.3737 mGy, while the highest ESD value was at the use of a voltage of 80 kV, which was 0.7328 mGy. Based on the calculation of hereditary effects for generation I has the highest probability compared to generation II, this is very dependent on the ability of cells after exposure to radiation. Cells in general can make natural repairs. The longer the time after exposure to radiation, the more cells have the opportunity to repair the effects of radiation. So the probability of the risk of hereditary effects in generation II will be smaller.

Abstract

It has been investigated the effect of field of view (FOV) on image quality produced by a CT Scan using the noise uniformity method with a phantom head. The FOV variations used are 180, 200, 220, 240 and 260 mm. The exposure time current and tube voltage used are 220 mAs and 130 kV, while the scan length and slice thickness used were 40 mm and 3 mm. Analysis of the effect of FOV variation on noise uniformity is determined by the standard deviation value obtained when performing ROI. Based on the standard deviation value, which shows that FOV variation affects the noise uniformity value, where the large increase in FOV, the noise uniformity is getting smaller and the resulting image quality is getting better

Abstract

The study aims to determine the effective dose to critical organs in head CT scans at RSUD Bali Mandara and analyse the difference in effective dose between male and female patients and compare it with BAPETEN's normal threshold. Secondary data including current, voltage, CTDIvol, and DLP were collected and grouped by gender. The effective dose was calculated by multiplying DLP by the conversion factor K and CTDIvol by the organ weight factor (WT). The mean effective dose of male patients was 4.35 ± 0.68 mGy, while that of female patients was 4.00 ± 0.53 mGy. The effective dose of critical organs for males was 0.642 mGy and for females 0.613 mGy, with higher doses for males. Statistical analysis using t-test shows the value of tcount < ttable, which indicates that the effective dose in head CT scan examination at RSUD Bali Mandara is still within normal limits according to the BAPETEN DRL standard Number: 1211/K/V/2021.

Abstract

Research has been carried out on radiation dose rate analysis in the CT-SCAN area of the radiology room at RSU Mandara Bali. The data used in this research is quantitative data observed from the radiation rate from the CT-SCAN aircraft. This study aims to determine the radiation dose rate in the radiology area and its rationalization based on regulations regarding radiation NBD (dose limit values) that apply to occupational safety and health. The research data is the actual radiation dose rate determined from the dose rate and calibration factors. The results of data calculations show that the highest dose rates are respectively at T2, 30 cm, 50 cm and 100 cm (door) with values of 1.95, 0.94 and 0.05 μSv/year, while the lowest dose rates are respectively at T4, 30 cm, 50 cm and 100 cm (waiting room) with values of 0.08, 0.06 and 0.05 μSv/year. The research results show that the dose rate at each measurement point is still considered safe for radiation workers where the NBD received is still below 20 μSv/year, while the dose rate is classified as safe for the general public at measuring distances of 50 cm and 100 cm, where the NBD received is below 1 μSv/year assuming the community concerned acts as a patient or patient's family with an interest in the radiology room area.

Abstract

Coronavirus Desease 2019 (Covid-19) merupakan penyakit menular yang disebabkan oleh virus Sars-Cov-2. Gejala yang ditimbulkan antara lain demam, batuk kering, dan sesak napas. Berbagai upaya penanganan dan pencegahan dilakukan oleh tenaga medis di Indonesia. Salah satu rumah sakit yang ikut andil menangani hal tersebut adalah RSUP Prof. Dr. I. G. N. G Ngoerah yang ada di Provinsi Bali menggunakan pemeriksaan thorax dengan pesawat sinar-X (rontgen). Penelitian ini dilakukan dengan menggunakan data sekunder yaitu 30 data pasien non-Covid-19 dan 30 data pasien Covid-19 di RSUP Prof. Dr. I. G. N. G Ngoerah pada tahun 2020 sampai dengan tahun 2022 dengan membandingkan hasil citra pasien secara kualitatif dari pembacaan dokter radiolog dan secara kuantitatif dilihat dari nilaia Efekti Dose (ED) dan Indeks Exsposure (IE). Dari hasil citra, pasien covid-19 menunjukkan adanya bercak-bercak putih pada bagian paru-paru dan dari hasil pembacaan dokter rata-rata pasien covid-19 mengalami pneumonia atau peradangan pada paru-paru sedangkan pada pasien non-covid-19 tidak mengalami pneumonia. Secara kuantitatif rata-rata nilai ED pada pasien non-covid-19 lebih besar dibandingkan pada pasien covid-19. Secara berturut-turut yaitu 0,1267±0,00653 mSv dengan nilai minimum 0,0694 serta nilai maximum 0,214 dan 0.0914±0,0311 mSv minimum 0,0096 serta maximum 0,706.  namun nilai IE pada pasien covid-19 lebih besar dibandingkan dengan pasien non-covid-19, yaitu 267,3±9,059 mSv dengan nilai minimum 202 mSv dan maximum 396,1 mSv. Sedangkan pasien non-Covid-19 besar nilai minimum 129 mSv dan maximum 172,9 mSv dengan rata-rata 146,467±2,45 mSv, dengan persentase perbandingan yaitu 35%:65%. Untuk menunjang terhadap perbedaan yang terjadi maka dilakukan uji statistik menggunakan T-test statistik nonparametric. Syarat signifikansi Asimp.Sig<0,05 menunjukkan perbedaan yang signifikan antara IE pasien non-Covid-19 dengan IE pasien Covid-19. Sehingga hasil statistik juga mendukung terhadap hasil pembacaan IE pada citra radiografi bahwa terjadi perbedaan yang signifikan antara nilai IE pada citra radiografi pasien non-Covid-19 dengan pasien Covid-19.
