Abstract

Penelitian ini bertujuan untuk mengetahui perkembangan ovarium tikus putih (Rattus norvegicus) galur Wistar yang dipapar radiasi sinar X, meliputi bobot dan gambaran histologisnya.  Penelitian menggunakan 20 ekor tikus betina usia 1,5 bulan dengan bobot badan rata-rata 150±13 gram.  Tikus  dikelompokkan ke dalam 4 perlakuan yaitu  perlakuan dosis radiasi sinar X sebesar 50, 100 dan 150 mGray serta satu kelompok kontrol. Variabel yang diukur meliputi bobot ovarium utuh dan gambaran histologis ovarium. Radiasi dilakukan dengan cara penyinaran satu kali tembakan pada setiap tikus per hari selama 5 hari.  Analisis data bobot ovarium dilakukan dengan dengan anova satu arah dilanjutkan dengan uji LSD pada taraf signifikansi 5%, sedangkan untuk data kualitatif gambaran histologis ovarium dianalisis secara deskriptif. Hasil analisis statistik memperlihatkan bahwa perlakuan dosis radiasi 50, 100 dan 150 mGray berpengaruh nyata terhadap bobot ovarium, yakni cenderung menurun dibanding kelompok kontrol. Pengamatan terhadap gambaran histologis ovarium memperlihatkan kerusakan ovarium mulai terjadi pada dosis 100 dan 150 mGray. Penelitian ini menyimpulkan bahwa paparan radiasi sinar X menyebabkan penurunan bobot ovarium dan pada dosis 100 mGray telah menimbulkan tanda kerusakan pada struktur histologi ovarium tikus putih galur Wistar.This study aims to determine ovarian development of rats (Rattus norvegicus) after exposure X-ray radiation, especially weights and ovarian histology. The study used 12 female rats of 1.5 months and average body weight of 150 ± 13 grams. Female rats were devided into four groups: control, and variations in dose of 50 mGray (T1), 100 mGray (T2) and 150 mGray (T3). This study used a complete randomized block design.  Radiation is done by irradiating one shot on each rat per day for 5 days. Statistical analysis for ovarian weight was performed by one way Anova and LSD Test, while qualitative data of ovarian histological were analyzed descriptively. The results showed that the variations in dose of  X-ray radiation significantly (P ≤ 5 %) of the ovarian weight. LSD test results further demonstrate that treatment of radiation doses 50, 100 and 150 mGray significant effect on ovarian weight, which decreases compared to the control group. This study concluded that exposure to X-ray radiation causes a decrease in ovarian weight and radiation dose of 100 mGray has caused damage to the structure of the ovarian histology Wistar rats.

Abstract

The aim of this study is to design a batik coloring machine using the Quality Function Deployment (QFD) method in order to increase the value of fading and stains on fabrics. It can be concluded that the results of the design of batik coloring machines according to the application of QFD have 3 rollers/cylinders and propulsion about 0.190 HP with the working concept of a sheet of cloth wrapped around the cylinder with rotation of 72.5 rpm. There are significant differences between variables in the design before and after the experiment on the batik value quality analysis of soap washing and desecration of unbleached plain cloth of Primisima type, Gamelan stamp. The average difference between before and after the experiment is 0.060 or increase to 6%, while for the analysis of batik quality test, the value of rubbing dry and wet cloth has a mean difference between before and after the experiment of 0.100 or an increase of 10%. Standard time generated from the measurement process using a machine dipping carried out by 20 batik makers has a value of 0.2701 hours/ unit with total output of 4 units/ hour, while standard time for coloring activities that uses a bucket dip is 0.5346 hours / unit with total output of 2 units/ hour.
