ABSTRACT: Modification of threshold exemption from import duties was tested whether changing consumer preferences in shopping from abroad. This study uses a paired test with the initial hypothesis that there is no difference in the daily average value of imports before and after the policy is applied. The research data is only from the Customs offices which have services for shipment items (32 offices) on October 1, 2019, to March 2, 2020. Descriptive statistical results show that the average was USD135,065, then dropped to USD127,430. Based on the results, both the Paired Sample T Test and The Wilcoxon Signed Rank Test obtained a p-value of 0,000, meaning that the initial hypothesis was rejected. The adoption of this policy has changed the preferences of consumers shopping from abroad. The Government's aim to reduce the trade balance deficit and protect domestic businesses appears to be successful, however, if there are no substitute goods available in the country, the import will only move from importing consignment goods to general imports. The novelty is the variable of import duty on shopping preferences is not widely used. The limitation of this study only measures changes in spending preferences, do not in state revenue.Keywords: shopping preference, consignment, tax exemption, difference test ABSTRAK:Perubahan kebijakan batas pembebasan terhadap bea masuk dan pajak atas impor barang kiriman diuji apakah merubah preferensi konsumen dalam berbelanja barang yang dikirim langsung dari luar negeri melalui mekanisme impor barang kiriman. Penelitian ini menggunakan metode kuantitatif melalui uji berpasangan dengan hipotesis awal tidak adanya perbedaan nilai rerata impor harian baik sebelum maupun setelah kebijakan berlaku. Data penelitian hanya kantor-kantor Bea Cukai yang memiliki pelayanan atas barang kiriman (32 kantor) pada 1 Oktober 2019 sampai dengan 2 Maret 2020. Hasil statistik deskriptif menunjukkan bahwa rerata harian impor sebelum kebijakan tersebut berlaku sebesar USD135.065, kemudian turun menjadi USD127.430. Berdasarkan pengujian, baik pada Paired Sampel T Test maupun pada Wilcoxon Signed Rank Test diperoleh nilai p sebesar 0.000 (hipotesis awal ditolak). Hal ini berarti penerapan kebijakan tersebut telah merubah preferensi belanja dari luar negeri melalui impor barang kiriman. Tujuan Pemerintah untuk mengurangi defisit neraca perdagangan dan melindungi usaha dalam negeri tampaknya berhasil, namun apabila belum tersedia barang subtitusi di dalam negeri, importasi tersebut hanya akan berpindah dari impor barang kiriman menjadi impor umum. Keterbaruan pada penelitian ini adalah variabel bea masuk pada preferensi belanja belum banyak digunakan. Keterbatasan penelitian ini hanya mengukur perubahan preferensi belanja, tidak mengukur perubahan penerimaan negara.Kata Kunci: preferensi belanja, impor barang kiriman, pembebasan pajak, uji beda

Introduction: Generally, core stability exercise as a training program is needed in almost kind of sport including paddle, analysis of movement in any kind of paddle sport such as kayak, canoe, or even rowing have been showed that the activity of core stability muscles are really needed. Purpose: purpose of this research is to know the effectivity of core stability exercise replenishment to increase sculling speed in paddle training program. Methods: This research is experimental with treatment by subject design project, involving 15 paddle athletes which divided into two groups and consists of II periods which are, Period I and Period II. In the 1st period, the athletes were given extra core stability exercise along with their normal paddling routine mean while in the 2nd period, the athletes only doing their normal paddling routine. Each period do the trial in 6 weeks, so this reseach took 12 weeks. In 1st period, the subjects were given extra core stability training 3 times a week along with their normal paddling routine where as subjects in period II only do their normal paddling routine. Results: The used of parametric paired t test is to know the difference of sculling speed before and after the trials were given. To period I pre test value is 3.80 ± 0.26 meters/second while the post test value is 4.06 ± 0.41 meters/second and the value 0.001 (p<0.05)mean while the 2nd period use Wilcoxon signed rank test to know the difference of sculling speed between before and after the trial were given resulting pre test value 3.80 ± 0.22 meters/second and post test value 3.91 ± 0.27 meters/second while the p value is 0.004 (p<0.05). After 12 weeks of sculling speed test between both period using Wilcoxon signed rank test and resulting obvions with period I value 0.26 ± 0.20 meters/second and period II value is 0.11 ± 0.12 meters/second along with p value 0.001 (p<0.05). Conclusion: Therefore, based on the result of my research test, we can concluded that the addition of core stability exercise in paddle training program is more effective to increase sculling speed.

AbstractThe evaluation of geoscience data is a far-reaching topic which cannot be systematically covered. The purpose of inferential statistics is to harness useful information from data for making decisions. This paper conducts in-depth statistical study for the Bursa-Wolf and Molodensky Badekas models of the three-dimensional transformation parameters. We also considered the combined and observation equations scenarios of these methods for the comparative study. Four key indicators are conducted to evaluate the performance of the two transformation models according to the residual results. These include root mean square error (RMSE), paired t-test, Wilcoxon signed-rank test and the Cohen’s d effect size measure. RMSE evaluation is based on the mean difference between model estimates and observed values. The correlations in the model results is investigated based on paired t-test. Wilcoxon signed-rank test assesses the statistical significance of the model’s paired differences. To estimate the effect size of the performance differences, Cohen’s d measures are computed. Further, the residuals of the estimated parameters are plotted according to their respective control points. The inference results of these tests generally show that Badekas transformation approach is more precise than Bursa-Wolf. Specifically, Badekas combined case is the most precise, followed by its observation case, then Bursa-Wolf combined and finally its observation case is the least performing model. The application of various data analysis and statistical verifications make the task of data interpretation and best model selection easier.

Abstract Background The gastrointestinal microbiota in chicken ( Gallus gallus domesticus ) has a central role in health and performance. The ceca are a vital site of functional activity, but assessing cecal microbiota in longitudinal studies remains a challenge. The cecal communities are broadly similar to large intestine samples. Cloacal sampling, due to their proximity to the large intestine, is an alternative, non-invasive method used for assaying and monitoring disease-causing agents, and maybe a viable option for longitudinal studies. Results We collected paired cecal content, and cloacal swab samples from twenty randomly selected commercial broilers raised on two dietary treatments. The microbiota of each sample was assessed using 16S rRNA V4 hypervariable region sequencing on an Illumina MiSeq platform and analyzed using the MOTHUR pipeline. Analysis of fourteen paired samples resulted in 1603 OTU’s assigned to 82 Families. Eleven families were shared between the cecal and cloacal samples, with seven and eleven families unique to cecal content and cloacal swabs, respectively. Paired t-test and Wilcoxon Signed-Rank test showed significant differences in the Chao1 index between the cecal content and cloacal swabs (p-value = 0.000845 and p-value = 0.001397, respectively). However, the Inverse Simpson species diversity estimator was not different using the Wilcoxon Signed-Rank test (p-value = 0.3258) and a paired t-test (p-value = 0.3864). β-diversity between the cloacal swabs and cecal microbiota also showed significant differences based on PERMANOVA (p-value = <0.001), HOMOVA (p-value <0.001), and Weighted Unifrac (WSig = <0.001) testing. Conclusions Cloacal swabs do not approximate either the α or β diversity of cecal samples, based on a paired sample analysis. The high variability of cloacal microbiota has been reported previously, and this study provides additional evidence of the randomness of cloacal microbiota in contrast to cecal microbiota. Our findings indicate that cloacal samples are not suitable for longitudinal studies of gut microbiota patterns. High inter-individual variation of cloacal swab data warrants further assessment of their reliability as a targeted diagnostic method.

This research aims to study the effect of inquiry learning by critical thinking practice followed by a conceptual change efforts to reduce misconceptions on acid-base learn. The research design using one-group pretest-posttest design with students of SMAN 2 Ngawi as sample research. The student conception  status finding by knowing concept (TK), not knowing concept (TTK), and misconception (MK), whereas intensity of misconception be analized by CRI. Results and analysis of research data found that there is a shift in conception after inquiry learning p rocess. Based on Wilcoxon’s signed rank test, the T value of test TK, TTK, and MK is less than T table at α = 0.05 , so it was concluded that inquiry learning increase TK and decrease TTK and MK. The influence of inquiry learning for understanding the influence was strengthened by the results of the t test tests before and after understanding the concept of inquiry learning that indicate a significant difference.  t-test results on tests of critical thinking before and after the inquiry learning also showed a significant difference. Inquiry learning can not reduce all of misconceptions. Reduction step again is with conceptual change. Based on Wilcoxon’s signed rank test was concluded that conceptual change learning can reduce misconception significantlyPenelitian ini bertujuan mempelajari pengaruh pembelajaran inkuiri terbuka disertai latihan berpikir kritis yang dilanjutkan dengan conceptual change sebagai upaya mereduksi miskonsepsi pada materi asam basa. Penelitian eksperimen semu ini menggunakan metode one group pretest-postest design dengan subyek penelitian  siswa kelas XI SMA Negeri 2 Ngawi. Profil konsepsi siswa dinyatakan dengan status tahu konsep (TK), tidak tahu konsep (TTK), dan miskonsepsi (MK), sedangkan intensitas miskonsepsi diperoleh dari hasil analisis CRI jawaban siswa.  Hasil dan analisis hasil tes pemahaman konsep menemukan bahwa terjadi pergeseran konsepsi setelah proses pembelajaran inkuiri terbuka. Berdasarkan wilcoxon’s signed rank test diperoleh T hitung untuk semua status TK, TTK, dan MK kurang dari nilai T tabel pada α = 0,05 dan n = 25, sehingga   disimpulkan bahwa pembelajaran inkuiri meningkatkan jumlah TK dan menurunkan TTK dan MK.  Pengaruh pembelajaran inkuiri terhadap pemahaman konsep serta kemampuan berpikir kritis diketahui dari uji t hasil tes pemahaman konsep serta tes berpikir kritis sebelum dan setelah pembelajaran. Hasil uji t pada α = 0,05 menunjukkan adanya perbedaan signifikan pemahaman konsep serta kemampuan berpikir kritis antara sebelum dan setelah pembelajaran inkuiri. Miskonsepsi yang masih tersisa setelah pembelajaran inkuiri direduksi kembali dengan strategi   conceptual change. Berdasarkan wilcoxon’s signed rangk test disimpulkan bahwa pembelajaran conceptual change dapat mereduksi miskonsepsi secara signifikan.
