Abstract

The purpose of this study was to determine the effect of thawing time on the quality of frozen semen of Limousin cattle. This study used an experimental method with a completely randomized design (CRD) with 4 treatments, namely thawing time of 0 seconds, 30 seconds, 60 seconds and 90 seconds at 38oC and 4 replications. The material in this study was frozen semen of 16 straws of Limousin cattle with the same stud code. This research was conducted at the Laboratory of Animal Biotechnology, Andalas University, Padang. From the results of the study, it can be seen that the thawing time of 0 seconds, 30 seconds, 60 seconds and 90 seconds gave a very significant difference (P<0.01) for the percentage of life, percentage of motility and percentage of abnormalities that were thawed at 38oC. It was concludedthat the effect of thawing time of 0 seconds was high on the percentage of motility, percentage of survival and percentage of abnormalities for thawing that could cause spermatozoa (cold shock) or damage.

Abstract

Pemeliharaan prediktif biasanya menggunakan alat untuk mendeteksi sebelum kerusakan suatumesin itu bertambah parah, hal ini dengan cara pengamatan (monitoring) baik secara berkala(off-line) maupun secara langsung (on-line). Pada penelitian ini dilakukan merupakan suatu studikasus di suatu perusahaan dimana mesin blower untuk flue gas dilakukan pengamatan awaldengan metode LDR kemudian dilanjutkan dengan pengambilan data getaran / vibrasi pada nilairms, jika nilai yang diambil diluar batas kewajaran / mengkhawatirkan sesuai standard ISO makadilanjutkan dengan alat vibration analyzer untuk mengetahui kondisi abnormal tersebut. Hasilpemeriksaan pada NDE bearing posisi horizontal memiliki nilai 7,74 mm/s dan timbul spektrum1X unballance sehingga dilakukan re-balance pada impeller sehingga berhasil menurunkan nilaimenjadi 2,1 mm/s. Proses balancing ulang berhasil sesuai hukum yang ada walaupun secaraaktual nilai FFT bergerak dan kadang tidak stabil karena unsur lain semisal pondasi yang sudahtidak normal, bearing yang bermasalah atau kurang pelumasan, resonansi dari mesin sekitarnyadan lain sebagainya.

Abstract

Mesin berputar di Industri akan menimbulkan getaran yang dihasilkan oleh mesin tersebut. Pengukuran getaran merupakan bagian dari pemeliharaan prediktif. Penelitian ini membuat mesin sederhana berupa modul getaran rotor dengan cara menganalisis spektrum FFT getaran yang ditimbulkan pada journal bearing dengan variasi kecepatan putar 1500-2500 Rpm dengan kenaikan putar sebesar 200 Rpm dan variasi viskositas oli menggunakan SAE 30 dan SAE 40. Hasil pengukuran getaran berupa spektrum FFT menunjukan adanya kondisi unbalance karena timbulnya 1x Rpm, disamping penggunaan jenis kekentalan oli dan kecepatan putaran poros yang bervariasi sangat mempengaruhi amplitudo getaran, nilai getaran tertinggi sebesar 0.5 mm/s untuk kondisi oli SAE 30 dan 0.4 mm/s untuk kondisi oli SAE 40 pada kecepatan poros 2300 Rpm serta mengalami penurunan nilai amplitudo getaran pada kecepatan putaran 2500 Rpm dengan nilai amplitudo 0.3 mm/s untuk kondisi oli SAE 30 dan 0.2 mm/s untuk kondisi oli SAE 40.

Abstract

This research aims to evaluate the effectiveness of using Educandy media towards students’ vocabulary of eighth-grade students at SMPN 10 Serang. A quantitative approach with a quasi-experimental design was utilized to systematically analyze the impact of Educandy on students' vocabulary acquisition. Participants were divided into two classes, selected through purposive sampling. The main data collection tool was a test, consisting of a pre-test and a post-test. The pre-test, administered at the study's outset, established a baseline of students' vocabulary knowledge, while the post-test, given at the study's conclusion, assessed any vocabulary improvements due to the Educandy intervention. Data were analyzed using a T-test to compare the performance of the two classes. Results indicated significant differences in vocabulary acquisition between the experimental group, which used Educandy, and the control group, which did not. The significance value (2-tailed) was below 0.05, indicating a statistically significant improvement in the vocabulary of students who used Educandy media. Consequently, the alternative hypothesis (Ha) was accepted, and the null hypothesis (H0) was rejected. These findings suggest that Educandy media is an effective tool for enhancing vocabulary among eighth-grade students. Thus, it can be concluded that Educandy media effectively improves the vocabulary of eighth-grade students at SMPN 10 Serang.

Abstract

Penelitian ini dilakukan untuk menganalisis faktor-faktor yang mempengaruhi konsumen dalam menabung di perbankan syariah karena perilaku konsumen merupakan pertimbangan yang cukup penting untuk diperhatikan dengan memahami preferensi masyarakat terhadap bank syariah maka bank tersebut dapat menyusun strategi marketnya demi meraih pangsa pasar dan menciptakan kepuasan pelanggan, serta memberikan informasi yang benar dan terpercaya kepada masyarakat luas sehingga masyarakat memiliki keinginan besar untuk memanfaatkan jasa perbankan syariah. Dari hasil pengujian sebelunya terlihat bahwa nilai korelasi (r) antara produk dengan perilaku konsumen adalah 0.474. Nilai ini adalah yang positif, artinya ada hubungan yang searah antara Produk dengan perilaku konsumen, atau dengan kata lain jika produk-porduk yang ditawarkan perbankan meningkat maka perilaku konsumen untuk menabung di Bank Mandiri Syariah pun juga meningkat, demikian pula selanjutnya jika produk-produk yang ditawarkan perbankan syriah buruk atau rendah maka perilaku konsumen untuk menabung di Bank Mandiri Syariah pun rendah.

Abstract

Tax avoidance is based on agency theory, where this theory explains that a company is a form of contract between the owner of the company (principal) and the manager (agent) of the company who takes care of use and control within the company. This study aims to determine the effect of inventory intensity, leverage and financial performance on tax avoidance in LQ-45 index companies for the 2017-2021 period. This type of research is quantitative using secondary data obtained from the Indonesia Stock Exchange (IDX) and the website of each company and the analysis technique used in this study uses multiple linear regression with the help of E-views version 10 software. This research was conducted at companies LQ-45 index. The data sampling technique uses purposive sampling, which are used as research samples are 21 companies with security for 5 years 2017-2021. The results showed that partially leverage and financial performance had no effect on tax evasion while inventory intensity had an effect on tax evasion. While simultaneously inventory intensity, leverage and financial performance have an influence on tax avoidance.

Abstract

Tuberculosis (TB) remains Indonesia's leading infectious disease. Hepatotoxicity is the most common side effect of TB first-line medication therapy in TB patients. GSTM1 and GSTT1 are glutathione S-transferase (GST) genes involved in the detoxification of various toxic compounds such as drugs. The development of fast and simple methods for null genotyping of GSTM1/GSTT1 could facilitate large pharmacogenetic studies and the clinical application of personalized drug dose adjustment according to the patient's genetic profile. The aim of this research was to develop a multiple PCR method for simultaneous amplification of GSTM1/GSTT1 genes for molecular analysis. A total of 25 samples of TB patients were used to validate the method consisting of TB patients with hepatotoxicity and without hepatotoxicity. Our result showed the genotype frequency of the GSTM1 null genotype was 90% in TB patients with hepatotoxicity and 100% in TB patients without hepatotoxicity. The frequency of the GSTT1 null genotype in TB patients with hepatotoxicity was 90%, whereas in TB patients without hepatotoxicity was 80%. The sequencing results on the positive samples showed a similarity of 99% to the GenBank NCBI. Our study was successful in detecting GSTM1 and GSTT1 null genotypes using the multiplex PCR method in TB patients. Further study needs to be done with larger sample of TB patients.
